Allocating the REDD+ national baseline to local projects: A case study of Cambodia

This study aimed to propose a set of decision support tools to allocate Cambodia's REDD+ national baseline or initial forest reference level (FRL) to local REDD+ projects, based on their forest cover and forest carbon stocks, and the historical deforestation trends in their reference regions. Our samples included 77 hypothetical REDD+ projects and five actual REDD+ projects. To identify reference regions for our samples, a cluster analysis of 127 districts in Cambodia was conducted using the Partitioning Around Medoids (PAM) algorithm (or k-medoids method). To calculate the baseline amount to be allocated to projects, four allocation methods were proposed. Two methods used ‘snapshot’ variables (i.e., [1] existing forest area or [2] forest carbon stock) and two used ‘change’ variables (i.e., [3] historical forest area change or [4] historical forest carbon stock change from 2006 to 2014). We weighted the baseline by the deforestation risk in 2014. We found that ‘snapshot’ methods tended to allocate more baseline if the project had more forest cover or forest carbon stocks. In contrast, ‘change’ methods tended to allocate more baseline if the project has more forest area loss or forest carbon stock loss between 2006 and 2014 in its reference region. These differences suggest that the ‘snapshot’ methods do not consider the inequity in the amount of baseline allocated to the projects. This inequity stems from the different degree of effort made by project stakeholders to protect their forests. The degree of effort varies depending on the historical deforestation trend in a project's reference region. However, the ‘change’ methods explicitly incorporate the trend into their calculations of baseline allocations. Technically, the ‘change’ method [4] seems to be the desired choice for allocating FRL to local projects; this is because it fits best with the idea of counter-factual thinking using a ‘reference period’ that a national baseline must have under the United Nations Framework Convention on Climate Change (UNFCCC). The ‘change’ methods are less likely to stimulate further deforestation, in a jurisdiction with high forest cover or forest carbon stocks that does not have a REDD+ project, compared with the ‘snapshot’ methods. However, the ‘change’ methods are more likely to face the challenge of political adjustment to balance the reduced emissions from some jurisdictions/projects with increased emissions from the other jurisdictions/projects, compared with the ‘snapshot’ methods. The findings are applicable not only in Cambodia but also in other REDD+ countries that include deforestation as one of the five REDD+ activities, within the scope of their national baseline submission to the UNFCCC. The study's outcomes will facilitate stakeholder dialogue on the proportions of national baseline allocated to sub-national programs/projects by showing the technical and political implications of the proposed allocation methods.

Power, the Pacific Islands, and the Prestige Press: A Case Study of How Climate Reporting is Influenced by UN Framework Convention on Climate Change Summits

While studies have investigated UN Framework Convention on Climate Change (UNFCCC) meetings as drivers of climate change reporting as well as the geopolitical role of Pacific Islands in these international forums, little research examines the intersection: how media coverage of Pacific Islands and climate change (PICC) may be influenced by, or may influence, UNFCCC meetings. We analyze two decades of reporting on PICC in American, British, and Australian newspapers—looking at both volume and content of coverage—and expand the quantitative results with semi-structured interviews with journalists and Pacific stakeholders. Issue attention on PICC increases and the content changes significantly in the periods around UNFCCC meetings, with shifts from language about vulnerability outside of UNFCCC periods to language about agency and solutions. We explore the implications of these differences in coverage for both agenda setting and the amplification of emotional appeals in UNFCCC contexts.

Assessing the Greenhouse Gas Impact of a Renewable Energy Feed-in Tariff Policy in Mozambique: Towards NDC Ambition and Recommendations to Effectively Measure, Report, and Verify Its Implementation

Parties to the Paris Agreement (PA) have agreed on the goal of limiting the increase in global average temperature to well below 2 °C and are pursuing efforts to limit warming to 1.5 °C. Countries’ nationally determined contributions (NDCs) comprise the main framework used to achieve this. In this context, Mozambique′s NDC includes, amongst other actions, increased renewable energy (RE) generation. This article presents the results of the assessment of greenhouse gas (GHG) impacts of the Renewable Energy Feed-in Tariff (REFIT), using the Long-range Energy Alternatives Planning (LEAP) system model, in order to determine its potential contribution to Mozambique′s NDC’s goals and RE targets. Results from this study show that the REFIT regulation can be expected to contribute to reducing 0.34 MtCO2eq (0.6% of the NDC target for the electricity sector) by 2030, compared to a business-as-usual (BAU) scenario. However, the NDC ambition could be enhanced through the REFIT and contribute to reducing 2.54 MtCO2eq (4.3% of the NDC target for the electricity sector) by 2030. The article further discusses the requirements for a robust measuring, reporting, and verification (MRV) system for climate policies, using REFIT as a case study, to facilitate effective tracking of NDC progress and achievement and transparent reporting to the United Nations Framework Convention on Climate Change (UNFCCC).

Grand Challenges to Support the Freshwater Biodiversity Emergency Recovery Plan

The year 2021 offers a critical opportunity for concerted action to influence the future of freshwater biodiversity, ecosystem services and human well-being. The United Nations Decade on Biodiversity 2011–2020 has ended, and governments around the world are reviewing major international agreements relevant to biodiversity conservation, including the Convention on Biological Diversity (CBD)1, the Sustainable Development Goals (SDGs)2, and the UN Framework Convention on Climate Change (UNFCCC)3. A Post-2020 Global Biodiversity Framework4 is under development, with the grand mission to “Halt the loss of species, ecosystems and genetic diversity by 2030; restore and recover biodiversity to ensure a world of people “living in harmony with nature' by 2050”. Freshwater ecologists have acted quickly to draw attention to the global dimensions of the freshwater biodiversity crisis and address the lack of a comprehensive framework to guide policy responses (Bunn, 2016; Darwall et al., 2018). An Emergency Recovery Plan for freshwater biodiversity, published by 25 authors from 14 organizations (Tickner et al., 2020), sets out six major priorities for global action and policy development to “bend the curve of freshwater biodiversity loss.” It has been submitted to the working committees of the Post-2020 Global Biodiversity Framework, and further promoted as a dramatic OUPblog “Bring living waters back to our planet5” Comprehensive reviews have since enumerated many research questions, actions and policy refinements needed to “bend the curve” and protect the world's freshwater ecosystems (van Rees et al., 2020; Buxton et al., 2021; Harper et al., 2021; Maasri et al., 2021). Each review cuts across important scientific, societal, management and policy issues. The purpose of this brief challenge paper is, likewise, to strengthen and support the Emergency Recovery Plan, but in a different way, by advocating a broader package of strategic activities that too often operate in silos, with patchy coverage of the world's freshwater ecosystem types and biogeographic diversity. This package presents traditional areas of scientific and societal activity that require more strategic, integrated and collaborative global effort to deliver evidence-based freshwater conservation outcomes, conjoined with terrestrial and estuarine/marine conservation, depending on context: (i) inventory, evaluation and research; (ii) restoration and rehabilitation; (iii) protected area design and management; and (iv) socio-ecological science and governance. The paper is intended to motivate greater interest, commitment and collaboration of all stakeholders in the most urgent and ambitious conservation enterprise of the next decade—to protect and sustain freshwater biodiversity in the socio-ecological systems of the Anthropocene.

Scripting climate futures: The geographical assumptions of climate planning

Since 1992, the United Nations Framework Convention on Climate Change (UNFCCC), the global governing apparatus of climate planning, has privileged the sovereignty of territorial states. Contemporary political geographical scholarship has since called into question the coherency of the state as a unitary entity and as the sole legitimate arbiter of international politics. This article extends these contributions to planetary climate change adaptation. Through discourse analysis and the multi-scalar institutional and political history of climate planning, this article examines how normative discursive parameters enact prevailing political dynamics that script material futures. Drawing on recent climate planning reports of Palestine and Israel, this article investigates how state discourses operate within an asymmetric geopolitical context where issues of territoriality, sovereignty, and statecraft remain fractured and contested. Climate planning in Israel/Palestine exposes two key institutional constraints of climate governance. First, technical-managerial principles prescribe ahistorical adaptation measures that inadequately address inherently political constraints. Second, the elision of political-economic and historical-cultural contingencies in favor of a universalizing geophysical representation of climate change elides the systemic production of differentiated vulnerability. Consequential of an anachronistic politics of recognition within the UNFCCC, the conditions of climate governance may ultimately embolden the asymmetric status quo. I conclude by highlighting the spatial manifestations (both material and symbolic) of Israeli sovereign violence and the chronic indeterminacy of Palestinian territoriality produced by discursive climate futures.

Emerging reporting and verification needs under the Paris Agreement: How can the research community effectively contribute?

Greenhouse gas (GHG) emission inventories represent the link between national and international political actions on climate change, and climate and environmental sciences. Inventory agencies need to include, in national GHG inventories, emission and removal estimates based on scientific data following specific reporting guidance under the United Nation Framework Convention on Climate Change (UNFCCC) and the Paris Agreement, using the methodologies defined in the Intergovernmental Panel on Climate Change (IPCC) Guidelines. Often however, research communities and inventory agencies have approached the problem of climate change from different angles and by using terminologies, metrics, rules and approaches that do not always match. This is particularly true dealing with “Land Use, Land-Use Change and Forestry” (LULUCF), the most challenging among the inventory sectors to deal with, mainly because of high level of complexity of its carbon dynamics and the difficulties in disaggregating the fluxes between those caused by natural and anthropogenic processes.In this paper, we facilitate the understanding by research communities of the current (UNFCCC) and future (under the Paris Agreement) reporting requirements, and we identify the main issues and topics that should be considered when targeting improvement of the GHG inventory.In relation to these topics, we describe where and how the research community can contribute to producing useful inputs, data, methods and solutions for inventory agencies and policy makers, on the basis of available literature. However, a greater effort by both communities is desirable for closer cooperation and collaboration, for data sharing and the understanding of respective and common aims.

녹색기후기금의 개도국 기후기술 인큐베이터 및 액셀러레이터 프로그램 설계 요소 도출을 위한 사례 분석 연구

Under a new climate regime ushered in by adoption of the Paris Agreement, the importance of technological innovation efforts has been highlighted. Under the United Nations Framework Convention on Climate Change (UNFCCC), methods to support developing countries in terms of innovation, particularly, research, development, and demonstration (RD&D), have been explored by the Technology Mechanism and the Financial Mechanism. One such method is an incubator & accelerator program. This program is intended to help (technology) entrepreneurs or start-up companies in the process of leading novel technology commercialization. The Technology Mechanism has focused on the possible roles of this program, and the Green Climate Fund (GCF) of the Financial Mechanism under the UNFCCC has been preparing for the set-up of an incubator and accelerator program, called the Climate Innovation Facility (CIF), as a separate financial track to support developing countries’ climate technology start-ups and to trigger climate technology innovation. In this context, the design factors considered in the formation of a ‘climate technology’-targeted incubator & accelerator program of the GCF must be identified. This paper proposed an analytical framework with five key factors for design of successful incubator/accelerator programs on the basis of literature review. Three cases of successful ‘climate technology’ incubator & accelerator programs are selected for study: i) Climate-KIC, ii) Climate Knowledge and Innovation Community, and iii) Global Cleantech Innovation Programme. The afore-mentioned analytical framework is applied to all three cases. The analytical results indicated essential points to be considered in the design of a ‘climate technology’ incubator & accelerator program of the GCF. This paper concludes with policy and scholarly implications, weak points, and future research.

IMPLEMENTING EUROPEAN ENVIRONMENTAL POLICY IN THE EUROPEAN UNION AND TURKEY: THE COST AND EXPENDITURES OF THE POLICY COMPLIANCE

This paper examines the European environmental policy and the tools that the European Union (EU) uses for the aim of protecting the environment. Environmental policy is of crucial importance indeed as it has direct impact on human’s health, on the quality of environment, on the well-being of all living creatures and species and on the preservation of our natural resources around the world. The EU is quite active in environmental protection policy making and the scope of her environmental policy expanded with time, including nowadays many aspects such as air, water and soil pollution, waste management, protection of the environment, industrial pollution, chemicals, climate change and noise pollution. The methodology of the study consists of the review and analysis of primary and secondary sources regarding EU legislation on European environmental policy. The requirements of environmental policy are exposed and evaluated at the European level and other international engagements at the global level such as the United Nations Framework Convention on Climate Change (UNFCC), Kyoto Protocol and Paris Agreement are also evaluated in our paper. European statistics and reports are evaluated to provide a good understanding and assessment of the relation between governments and corporations’ expenditures and the protection of environment in EU member states and in Turkey. Our paper also includes the implementation of the European environmental policy in Turkey, therefore Turkish of􀏐icial policy alignment and compliance is explained with data related to EU funded projects implemented by Turkish institutions. Regarding the relation between expenditures and environment, our 􀏐indings indicate a reverse causality effect; the quality of the environment determines the level of public expenditures indeed, and not vice-versa. As analyzed in our paper, governments and corporations’ investments related to environmental protection are quite low and they are in decline, this share needs to be increased both at the EU level and in Turkey. Key Words: European Union Environmental Policy, Climate Change, Kyoto Protocol, Paris Agreement, Government Expenditures on Environmental Policy.

Overview of Legal and Policy Measures of Carbon Trading and Renewable Energy Certificate (REC) In India

It is scientifically well proven facts that carbon dioxide is the main cause of greenhouse gas emission by burning of fossils fuels. Kyoto Protocol to the United Nations Framework Convention on Climate Change (UNFCCC) empower the parties to curb greenhouse gas emissions from the diverse industries by elaborating the mechanisms of Clean Development Mechanism Joint Implementation, and Emission Trading. This has created an international market for carbon trading. The paper addresses the global and Indian’s national carbon trading system, starting with the UNFCCC, and Kyoto Protocol comprising carbon credit components. The paper also tries to examine the obligation of India under the Kyoto protocol and later discuss the legal and policy framework implemented by India to encourage CDM and carbon trading in India. It traces different policy measures like National Action Plan and State Action Plans on Climate Change, National Mission on Enhanced Energy Efficiency (NMEEE), Climate Change Action Program, 2010, Perform Achieve and Trade (PAT), Renewable Energy Credit Trading System (REC), PILOT ETS in some Indian provinces, the significant arrangements of Energy Conservation Act, 2001 and The Environmental Protection Act, 1986, Air (Prevention and Control of Pollution) Act, 1981 are likewise examined. This paper further discusses the positives and negative aspect of this scheme and also its review, criticisms and problems. It ends by providing an Indian perspective to this scheme. Study of this paper would be especially beneficial for the governments, stakeholders and research scholars to know the whole legal and policy mechanism of carbon trading.

Multi-level climate change planning: An analysis of the Italian case

As recognized by the Paris Climate Agreement of the United Nations Framework Convention on Climate Change (UNFCCC), local and subnational regions are crucial actors to achieve international mitigation and adaptation commitments. Scientific literature and empirical evidence point at multi-level climate governance as a crucial factor to engage subnational levels in the achievement of national and international objectives. This work focuses on the multi-level climate governance arrangements in Italy to investigate how Italian regions/provinces/cities are contributing to the achievement of national commitments. To this purpose, the paper undertakes a review of the climate policies of different tiers of government adopted to date and of the interrelationships among them. The results of the analysis show that the effective coordination between the different government levels should be strengthened to further incentivize and support initiatives at the local level. Results also show the relevant role played by international regional and city climate networks in boosting local and regional climate planning in Italy.

Assessing state compliance with multilateral climate transparency requirements: ‘Transparency Adherence Indices’ and their research and policy implications

ABSTRACT Transparency is increasingly central to multilateral climate governance. In this article, we undertake one of the first systematic assessments of the nature and extent of compliance with transparency requirements under the United Nations Framework Convention on Climate Change (UNFCCC). Extensive resources are now being devoted to setting up national and international transparency systems that aim to render visible what individual countries are doing with regard to climate change. It is widely assumed that such transparency is vital to securing accountability, trust and thereby also enhanced climate actions from all. Yet, whether transparency lives up to this transformative promise remains largely unexamined. We generate a first systematic overview here of the nature and extent of country engagement with and adherence to UNFCCC transparency requirements. Drawing on extensive primary documents, including national reports and technical expert assessments of these reports, we generate ‘Transparency Adherence Indices’ for developed and developing country Parties to the UNFCCC. Our results reveal wide variations in adherence to mandatory reporting requirements and no clear general pattern of improvement since 2014. Our Indices help to illustrate trends and highlight knowledge gaps around the observed adherence patterns. This is timely since the 2015 Paris Agreement calls for an ‘enhanced transparency framework’ to be implemented by 2024 that builds on existing UNFCCC transparency systems. We conclude with identifying a research and policy agenda to help explain observed patterns of adherence, and emphasize the need for continued scrutiny of assumed links between transparency and climate action. Key policy insights The UNFCCC and its 2015 Paris Agreement call for ever greater climate transparency from all countries. We develop ‘Transparency Adherence Indices’ that reveal frequency of engagement and adherence to reporting requirements of both developed and developing countries. Our findings reveal high engagement in transparency arrangements by developed countries and variable engagement from developing countries. We question what variable adherence to reporting requirements actually signifies, given how such adherence is assessed within UNFCCC technical expert reports. Further research to explain the range of observed adherence patterns is important, in light of the Paris Agreement’s requirements for enhanced transparency from all. The assumed link between enhanced transparency and climate action needs further analysis.

UNFCCC's posture on displacement riskification: Conceptual suggestions

This paper poses the question of whether the discussions within Task Force on Displacement (Task Force) meetings contribute to conceptualisation and riskification of climate-related displacement and slow-onset events. Arguing that the Task Force undertakes displacement riskification, the paper ascertains whether the discussions might be a cue for pinpointing the Task Force's posture on riskification of climate-related displacement. Centring on the Task Force's main mandate, the paper explains displacement riskification through discourse analysis of Task Force's discussions. Discourse analysis of policy statements showed that climate-related displacement and slow-onset events appear to be gaining purchase as part of the FCCC's climate diplomacy strategy because they are explicitly debated at Task Force meetings. The paper finds that the discussions made contributions, but are currently not being incorporated through statements that are reported to the Conference of Parties (COP) – the manager of the United Nations Framework Convention on Climate Change (FCCC). And finds that statements on and framings of displacement riskification may be considered definitive upon approval by the COP. The catch is that most security framings that can be found in the discussions within Task Force meetings has been poorly addressed at the COP mainly because the framings are largely absent in the Task Force reporting to the COP. These contributions/findings underpin the type of political knowledge mostly advanced and thus the likelihood of future directions of riskification politics by the Task Force.

APPLICATION OF THE KOLMOGOROV-SMIRNOV TEST TO COMPARE GREENHOUSE GAS EMISSIONS OVER TIME

The national inventories of greenhouse gas (GHG) emissions, which are periodically prepared by countries that signed the Climate Change Convention, compute emissions from anthropogenic sources among them agricultural activities. The protocols established within the scope of the International Panel on Climate Change (IPCC) make it possible to estimate these emissions. These protocols use standard emission factors that vary according to the characteristics of the monitored activities and only scientific research, published in journals of recognized quality, can establish other local factors. Brazilian researchers carry out experiments to measure GHG emissions from agricultural activities, aiming to calculate specific parameters for the national climatic and management conditions. These field experiments are complex, costly, with a limited number of repetitions and, eventually, high natural variability. Often, these limitations result in the inability of the analysis of variance (ANOVA) to identify differences between treatments. The objective of this work is to present the non-parametric Kolmogorov-Smirnov (KS) test as an alternative to compare the effect of flooded irrigation management on methane (CH4) emission throughout the rice crop cycle. We present a case study in which ANOVA produced non-significant results for the adjustment of the model while the KS identified the emission curves as significantly different. The KS test could be adapted, via the SAS NPAR1WAY routine, to compare events with responses over time, such as methane emissions in flooded rice, resulting in test values and graphs that are easy to understand and interpret.

Vulnerability of Temperate Fruit Production to Climate Change: Adaptation and Mitigation Measures: A Review

Climate change refers to a statistically significant variation in either the mean state of the climate or in its variability, persisting for an extended period (typically decades or longer). As per United Nations Framework Convention on Climate Change (UNFCCC), change of climate is attributed directly or indirectly to human activity that alters the composition of global atmosphere and which is in addition to natural climate variability observed over comparable time period. The earth’s climate, although relatively stable over the past 10,000 years or so, has always been changing, mainly due to natural causes such as volcanic activity. However, since the second half of 20th century more rapid change has taken place, which has been attributed mainly due to human activities. Plausible climate change scenarios include higher temperatures, changes in precipitation, and higher atmospheric CO2 concentrations. Temperate region of the country, comprising mainly north-west and north east Himalayan region has witnesses a dramatic change in climate over the past 30 years, where adverse effect of climate change on temperate fruit production has been noticed. The carbon dioxide, methane, nitrous oxide, sulpherdioxide, etc. form greenhouse gas (GHG) pools in the atmosphere. Increase in the concentration of these gases is responsible for global climate change. According to Inter Governmental Panel on climate Change (IPCC), the climate is defined as the average weather, or more rigorously, as the statistical description of the weather in terms of the mean and variability of relevant quantities over periods of several decades (typically three decades as defined by Meteorological Organization). These quantities are most often surface variables such as temperature, precipitation, and wind, but in a wider sense the climate is the description of the state of the climate system. Global climate change and increasing climatic variability are recently considered a huge concern worldwide due to enormous emissions of greenhouse gases to the atmosphere and its more apparent effect on fruit crops because of its perennial nature. The changed climatic parameters affect the crop physiology, biochemistry, floral biology, biotic stresses like disease pest incidence, etc. and ultimately resulted to the reduction of yield and quality of fruit crops. So, it is big challenge to the scientists of the world. Mitigation is the most important measures to reduce the devastating effect of climate change.

COMMITMENT TO REDUCE CONCENTRATION OF GREENHOUSE GASES: INTERNATIONAL RULES AND STATE PRACTICES

The climate change has become a global issue that has been primarily discussed in the last 20 years. In general, climate change occurs due to an increase in the earth's temperature which caused by an increase in the concentration of Greenhouse Gases (GHG) in the earth's atmosphere. This encourages the international community to form international policies related to the commitment of countries to reduce GHG concentrations with the formation of the United Nation Framework Convention on Climate Change (UNFCCC) which will formulate a common framework to tackle the climate change. This article analyzes agreements on climate change and the implementation of countries' commitments to reduce GHG concentrations. The purpose of this article is to find out about the international rules and practices of countries in reducing greenhouse gases.

Global methane budget and trend, 2010–2017: complementarity of inverse analyses using in situ (GLOBALVIEWplus CH<sub>4</sub> ObsPack) and satellite (GOSAT) observations

Abstract. We use satellite (GOSAT) and in situ (GLOBALVIEWplus CH4 ObsPack) observations of atmospheric methane in a joint global inversion of methane sources, sinks, and trends for the 2010–2017 period. The inversion is done by analytical solution to the Bayesian optimization problem, yielding closed-form estimates of information content to assess the consistency and complementarity (or redundancy) of the satellite and in situ data sets. We find that GOSAT and in situ observations are to a large extent complementary, with GOSAT providing a stronger overall constraint on the global methane distributions, but in situ observations being more important for northern midlatitudes and for relaxing global error correlations between methane emissions and the main methane sink (oxidation by OH radicals). The in-situ-only and the GOSAT-only inversions alone achieve 113 and 212 respective independent pieces of information (DOFS) for quantifying mean 2010–2017 anthropogenic emissions on 1009 global model grid elements, and respective DOFS of 67 and 122 for 2010–2017 emission trends. The joint GOSAT+ in situ inversion achieves DOFS of 262 and 161 for mean emissions and trends, respectively. Thus, the in situ data increase the global information content from the GOSAT-only inversion by 20 %–30 %. The in-situ-only and GOSAT-only inversions show consistent corrections to regional methane emissions but are less consistent in optimizing the global methane budget. The joint inversion finds that oil and gas emissions in the US and Canada are underestimated relative to the values reported by these countries to the United Nations Framework Convention on Climate Change (UNFCCC) and used here as prior estimates, whereas coal emissions in China are overestimated. Wetland emissions in North America are much lower than in the mean WetCHARTs inventory used as a prior estimate. Oil and gas emissions in the US increase over the 2010–2017 period but decrease in Canada and Europe. The joint inversion yields a global methane emission of 551 Tg a−1 averaged over 2010–2017 and a methane lifetime of 11.2 years against oxidation by tropospheric OH (86 % of the methane sink).

Mitigation of CO2 emissions from international shipping through national allocation

Neither international treaties nor domestic policies control carbon dioxide (CO2) emissions from international shipping. To enhance mitigation, a new multilateral mechanism could allocate these emissions to national carbon budgets, where different options could be used based on the location of industry actors and ships. We analyze five allocation options, showing that a clear majority of CO2 emissions would be distributed to ten countries under each option; however, the top ten countries vary across allocation options and the amount of CO2 emissions allotted to individual countries could increase their carbon budgets thousand-fold or more. We further examine how the different objectives, principles for decision-making, and geographical coverage of the United Nations Framework Convention on Climate Change (UNFCCC) and the International Maritime Organization influence the design and implementation of an allocation mechanism under each of these two bodies. We find that the allocation mechanism that best meets criteria related to effectiveness and equity would be one in which emissions are assigned to countries of ship owners, and which operates under the UNFCCC.

Model comparison and quantification of nitrous oxide emission and mitigation potential from maize and wheat fields at a global scale

Maize and wheat are major cereals that contribute two-thirds of the food energy intake globally. The two crops consume about 35% of the nitrogen (N) fertilizer used in agriculture and thereby contribute to fertilizer-induced nitrous oxide (N2O) emissions. Thus, estimation of spatially disaggregated N2O emissions from maize and wheat fields on a global scale could be useful for identifying emission and mitigation hotspots. It could also be needed for prioritizing mitigation options consistent with location-specific production and environmental goals. N2O emission from four models (CCAFS-MOT, IPCC Tier-I, IPCC Tier-II and Tropical N2O) using a standard gridded dataset from global maize and wheat fields were compared and their performance evaluated using measured N2O emission data points (777 globally distributed datapoints). The models were used to quantify spatially disaggregated N2O emission and mitigation potential from maize and wheat fields globally and the values were compared. Although the models differed in their performance of capturing the level of measured N2O emissions, they produced similar spatial patterns of annual N2O emissions from maize and wheat fields. Irrespective of the models, predicted N2O emissions per hectare were higher in some countries in East and South Asia, North America, and Western Europe, driven mainly by higher N application rates. The study indicated a substantial N2O abatement potential if application of excess N in the maize and wheat systems is reduced without compromising the yield of the crops through technological and crop management innovations. N2O mitigation potential is higher in those countries and regions where N application rates and current N2O emissions are already high. The estimated mitigation potentials are useful for hotspot countries to target fertilizer and crop management as one of the mitigation options in their Nationally Determined Contributions (NDCs) to the United Nations Framework Convention on Climate Change (UNFCCC).

Explaining elite perceptions of legitimacy in global governance

Elites are central in creating, operating, defending and contesting international organisations (IOs), but little research is available about their attitudes toward these bodies. To address this gap, this article offers the first systematic and comparative analysis of elite perceptions of IO legitimacy. Building on a unique multi-country and multi-sector survey of 860 elites undertaken in 2017–19, we map and explain elite legitimacy beliefs toward three key IOs in different issue-areas: the International Monetary Fund (IMF), the United Nations Framework Convention on Climate Change (UNFCCC) and the United Nations Security Council (UNSC). Integrating public opinion research and international relations theory, the article advances an explanation of elites’ legitimacy beliefs that emphasises their satisfaction with the institutional qualities of IOs. We contrast this argument with three common alternative explanations, which respectively highlight utilitarian calculation, global orientation and domestic cues. The analyses show that elites’ satisfaction with institutional qualities of IOs is most consistently related to legitimacy beliefs: when elites are more satisfied with democracy, effectiveness and fairness in IOs, they also regard these IOs as more legitimate. These findings suggest that the prevailing debate between utilitarian calculation, global orientation and domestic cues approaches neglects the importance of institutional satisfaction as an explanation of attitudes toward IOs.
