The Paris Agreement presents a historical landmark in the global response to climate change and sets out the objective of limiting global warming to well below 2 °C and pursuing efforts to limit the temperature increase to 1.5 °C above pre-industrial levels. However, the national climate change efforts to which Parties to the United Nations Framework Convention on Climate Change (UNFCCC) have committed themselves in the form of Nationally Determined Contributions (NDCs) are largely insufficient, and only cover one third of the greenhouse gas emissions reductions necessary to reach this temperature goal (UNEP 2017). There is still a significant gap between 2030 emission levels and a least-cost 2 °C pathway amounting to 11 GtCO2e or even as much as 13.5 GtCO2e, taking only unconditional NDCs into account (UNEP 2017). Global greenhouse gas emissions continue to rise, albeit at a slower rate, and even though the Parties must increase the goals of their NDCs over time, it is unlikely that the emissions reductions thus achieved will be sufficient (UNEP 2017).

Energy-related activities are a major contributor of greenhouse gas (GHG) emissions. A growing body of knowledge clearly depicts the links between human activities and climate change. Over the last century the burning of fossil fuels such as coal and oil and other human activities has released carbon dioxide (CO2) emissions and other heat-trapping GHG emissions into the atmosphere and thus increased the concentration of atmospheric CO2 emissions. The main human activities that emit CO2 emissions are (1) the combustion of fossil fuels to generate electricity, accounting for about 37% of total U.S. CO2 emissions and 31% of total U.S. GHG emissions in 2013, (2) the combustion of fossil fuels such as gasoline and diesel to transport people and goods, accounting for about 31% of total U.S. CO2 emissions and 26% of total U.S. GHG emissions in 2013, and (3) industrial processes such as the production and consumption of minerals and chemicals, accounting for about 15% of total U.S. CO2 emissions and 12% of total ...

Scaling up climate ambition post-2030: a long-term GHG mitigation analysis for Thailand

Thailand commits to achieving Carbon Neutrality by 2050 and net-zero GHG emissions by 2065. Its Nationally Determined Contributions (NDC) also aims to reduce greenhouse gas (GHG) emissions by 30% by 2030 through domestic efforts, termed “Unconditional NDC,” and up to 40% with international support, termed “Conditional NDC,” compared to its 2030 Business-as-Usual (BAU) of 555 MtCO2eq. This study explores the potential for reducing GHG emissions in Thailand's energy sector through international cooperation such as the Joint Credit Mechanism (JCM), in accordance with of the Paris Agreement (PA). It is essential that the results of international transfers are accurately accounted for and reported in the NDC tracking under Article 13 by both Parties to prevent double counting. The investigation utilizes the AIM/EndUse model, created by the National Institute for Environmental Studies in Japan. The results show that under the international cooperation framework, Thailand needs to reduce GHG emissions beyond the target specified in the conditional NDC. Finally, to enable the transfer of Internationally Transferred Mitigation Outcomes (ITMOs) under Article 6.2 of PA, Thailand's share of carbon credits should reasonably be capped at no more than 20%, with an additional emission reduction of 12.34 MtCO2 beyond the conditional Nationally Determined Contribution (NDC) target of 49.34 MtCO2.

Nationally Determined Contributions (NDCs), submitted by Parties to the United Nations Framework Convention on Climate Change before and after the 21st Conference of Parties, summarize domestic objectives for greenhouse gas (GHG) emissions reductions for the 2025–2030 time horizon. In the absence, for now, of detailed guidelines for the format of NDCs, ancillary data are needed to interpret some NDCs and project GHG emissions in 2030. Here, we provide an analysis of uncertainty sources and their impacts on 2030 global GHG emissions based on the sole and full achievement of the NDCs. We estimate that NDCs project into 56.8–66.5 Gt CO2eq yr−1 emissions in 2030 (90% confidence interval), which is higher than previous estimates, and with a larger uncertainty range. Despite these uncertainties, NDCs robustly shift GHG emissions towards emerging and developing countries and reduce international inequalities in per capita GHG emissions. Finally, we stress that current NDCs imply larger emissions reduction rates after 2030 than during the 2010–2030 period if long-term temperature goals are to be fulfilled. Our results highlight four requirements for the forthcoming ‘climate regime’: a clearer framework regarding future NDCs’ design, an increasing participation of emerging and developing countries in the global mitigation effort, an ambitious update mechanism in order to avoid hardly feasible decarbonization rates after 2030 and an anticipation of steep decreases in global emissions after 2030.

Greenhouse gas (GHG) emissions reduction in the electricity sector: Implications of increasing renewable energy penetration in Ghana's electricity generation mix

Major US electric utility climate pledges have the potential to collectively reduce power sector emissions by one-third

Urban water cycle systems(UWCS), including water treatment facilities, distribution facilities, sewers, and wastewater treatment facilities, are energy intensive and significant source of greenhouse gas (GHG) emissions, making the reduction of GHG emissions and the transition to eco-friendly energy essential. This study identifies specific GHG emission sources at each stage of the UWCS and proposes detailed methods to achieve a 40% reduction in GHG emissions, implement RE100, and attain Net Zero by employing insets and offsets. This study develops scenarios for insets and offsets based on the baseline process of the UWCS, and investigates potential pathways to reduce GHG emissions by quantifying emissions from each process. Internal insets, which are self-implemented and technical measures, are prioritized, while external offsets are applied to compensate for the remaining emissions. Internal insets include the application of anaerobic digesters and combined heat and power(CHP), improvements in energy efficiency of equipment, reduction in water pipe leakage, implementation of water footprint labeling, and installation of on-site photovoltaic system. External offsets comprise renewable energy certificates(REC), power purchase agreements(PPA), green hydrogen fuel for vehicles, natural sequestration improvement, and emission trading system. GHG emissions at each stage within the UWCS are quantified using modeling software. Based on these results, the effectiveness of insets and offsets in achieving a 40% GHG emissions reduction, Net Zero, and RE100 goal is analyzed. The baseline total GHG emissions for the UWCS are estimated at 4,732.8 tCO2eq/yr, of which 56.8% is identified as targets for internal insets, and the remaining 43.2% is reduced through external offsets. A 40% GHG reduction can be achieved through internal insets, and Net Zero can be attained by incorporating additionally applying external offsets. The total power demand of UWCS facilities and equipment is calculated as 572.8 kW. Renewable energy is generated through anaerobic digesters and CHP(116.1kW) as well as on-site PV(395.0 kW), while RE100 compliance is achieved by securing an aditional 61.7 kW through REC/PPA. Achieving Net Zero and RE100 requires prioritizing strategies for insets, offsets and efficient resource allocation. For this, the technical feasibility and self-implementation potential of reduction efforts and the external conditions for offsets, should be carefully reviewed to optimize implementation strategies. GHG reduction and renewable energy utilization in the UWCS are key priorities for addressing the climate crisis and achieving sustainable water resource management, requiring technological innovation and institutional support. The comprehensive and systematic application of GHG insets and offsets is the optimal approach to achieving these goals. Furthermore, modeling software serves as a key tool for quantifying GHG emissions and formulating concrete, viable GHG reduction strategies. In addition to the technical and institutional approaches proposed in this study, achieving Net Zero and implementing RE100 requires the integrated consideration of economic factors in the future.

GHG Mitigation in Power Sector: Analyzes of Renewable Energy Potential for Thailand’s NDC Roadmap in 2030

While the energy sector is the largest global contributor to greenhouse gas (GHG) emissions, the agriculture, forestry, and other land use (AFOLU) sector account for up to 80% of GHG emissions in the least developed countries (LDCs). Despite this, the nationally determined contributions (NDCs) of LDCs, including Nepal, focus primarily on climate mitigation in the energy sector. This paper introduces green growth—a way to foster economic growth while ensuring access to resources and environmental services—as an approach to improving climate policy coherence across sectors. Using Nepal as a case country, this study models the anticipated changes in resource use and GHG emissions between 2015 and 2030, that would result from implementing climate mitigation actions in Nepal's NDC. The model uses four different scenarios. They link NDC and policies across economic sectors and offer policy insights regarding (1) energy losses that could cost up to 10% of gross domestic product (GDP) by 2030, (2) protection of forest resources by reducing the use of biomass fuels from 465 million gigajoules (GJ) in 2015 to 195 million GJ in 2030, and (3) a significant reduction in GHG emissions by 2030 relative to the business‐as‐usual (BAU) case by greater use of electricity from hydropower rather than biomass. These policy insights are significant for Nepal and other LDCs as they seek an energy transition towards using more renewable energy and electricity.

The goal of limiting global temperature rise to “well below” 2 °C has been reaffirmed in the Paris Agreement on climate change at the 21st Conference of the Parties (COP21). Almost all countries submitted their decarbonization targets in their Intended Nationally Determined Contributions (INDC) to the United Nations Framework Convention on Climate Change (UNFCCC) and India did as well. India’s nationally determined contribution (NDC) aims to reduce greenhouse gas (GHG) emissions intensity of national GDP in 2030 by 33–35% compared to 2005. This paper analyzes how India’s NDC commitments compare with emission trajectories consistent with well below 2 °C and 1.5 °C global temperature stabilization goals. A top-down computable general equilibrium model is used for the analysis. Our analysis shows that there are significant emission gaps between NDC and global climate stabilization targets in 2030. The energy system requires significant changes, mostly relying on renewable energy and carbon capture and storage (CCS) technology. The mitigation costs would increase if India delays its abatement efforts and is locked into NDC pathways till 2030. India’s GHG emissions would peak 10 years earlier under 1.5 °C global temperature stabilization compared to the 2 °C goal. The results imply that India would need financial and technological support from developed countries to achieve emissions reductions aligned with the global long-term goal.

CONTENTS I Introduction II Climate Change and Extreme Weather Events III Adaptation in the International Climate Regime IV Insurance and Adaptation in the International Climate Regime V Models for Climate Change Insurance VI Caribbean Catastrophe Risk Insurance Facility VII Climate Change Insurance and the Pacific Island States VIII Viability of Climate Insurance as a Long-Term Adaptation Strategy IX Conclusion I INTRODUCTION Many Small Island Developing States ('SIDS') lie only metres above sea level, making them particularly vulnerable to the impacts of climate change in both the shorter (eg storm surge during large tropical cyclones) and longer (eg sea level rise) terms. (1) The modest ambition for mitigation (ie reduction) (2) of greenhouse gas emissions in the United Nations Framework Convention on Climate Change ('UNFCCC'), (3) Kyoto Protocol (4) and Copenhagen Accord (5) means that the prospect of avoiding an increase in mean surface temperature of less than two degrees is now very low. (6) The latest climate science suggests the Earth is on a path that will lead to a rise in mean surface temperature of between three and six degrees by 2100. (7) Unless there is a significant reduction in greenhouse gas emissions over coming decades, SIDS are likely to experience tropical cyclones of greater severity, disrupted rainfall patterns and sea level rise. (8) Recent extreme weather events in the Asia-Pacific region, such as Typhoon Haiyan (9) and Cyclone Ian, (10) demonstrate the significant impact of these events on SIDS. (11) The lack of success in mitigating greenhouse gas emissions has led to adaptation to climate change impacts gaining greater prominence within the United Nations climate negotiations. Adaptation to climate change has been defined as '[a]djustment in natural or human systems in response to actual or expected climatic stimuli or their effects, which moderates harm or exploits beneficial opportunities'. (12) Adaptation may take many forms, including pre-emptive action to limit damage from climate change-related events (eg implementing more ambitious building codes to make buildings more resilient to storms) and building institutions to aid recovery after a climate-related event (eg improving emergency services capacity to respond in the immediate aftermath of adverse weather events). Domestically, insurance is an established mechanism to spread financial risk of adverse events and build societal resilience. However, at an international level, the issue of climate change-related insurance has only proceeded in fits and starts. Proposals for an insurance mechanism to support the adaptation of SIDS to climate change date back to 1991. At that time, the Alliance of Small Island States ('AOSIS') proposed an international, state-based pool to provide insurance against the impacts of climate change-related sea-level rise. (13) Despite this early call by AOSIS, a climate change-related insurance mechanism was not included in either the UNFCCC or the Kyoto Protocol. In 2007 climate change-related insurance emerged again on the UNFCCC agenda as the Bali Action Plan launched international discussion on enhanced action on adaptation 'including risk sharing and transfer mechanisms such as insurance'. (14) In 2008 AOSIS made a submission under the Bali Action Plan to include an insurance mechanism as part of a broader response to climate-related loss and damage. (15) In a departure from its earlier proposal in 1991, the 2008 AOSIS submission called for insurance cover for climate change-related extreme weather events such as hurricanes, floods and droughts. (16) In 2010 the Cancun Agreements also invited submissions on the development of a climate risk insurance facility, as a part of an enhanced adaptation framework, to address impacts from extreme weather events. (17) The 2012 Conference of the Parties ('COP') 18 meeting in Doha appeared to be a breakthrough in the development of institutions to assist adaptation to climate change. …

The paper analyzes as to how Bangladesh can secure its future demand of electricity and mitigate greenhouse gas emission to meet the targets of Nationally Determined Contributions (NDCs). The overall objective of the study is to assess the possible mitigation of greenhouse gases emission for achieving NDCs from power sector of Bangladesh through solar photovoltaic systems. A quantitative analysis was done to project future power consumptions and greenhouse gas emissions up to 2030. A scenario analysis was also done to see the effects of different primary energy mix in power on the emissions. It is found that the total consumption in different sectors will increase with an increasing population and the GDP. Industrial and residential sectors are the main consumers of power. The scenario result shows that there is relationship between the energy mix and greenhouse gas emissions. The fossil fuels have higher emissions in the scenarios where they are thought to be main contributor to the energy mix. In case of high renewables, the emissions can be mitigated to meet the targets of NDCs. As Bangladesh receives high solar radiation, grid-connected solar photovoltaic systems can be the main source of renewable energy in such case. Therefore, solar photovoltaic technology is essentially required not only for achieving the targets of NDCs but also for the development of a low carbon power sector in Bangladesh for a sustainable future.

Climate change is a global collective action problem, which is primarily caused due to combination of the current Greenhouse Gas (GHG) emissions and the historical cumulative GHG emissions, contributed mainly by the developed countries. Even though India’s per capita GHG emission is minimal, India is committed to addressing the challenge with firm adherence to multilateralism, keeping in mind the national circumstances and based on equity and the principle of Common but Differentiated Responsibilities and Respective Capabilities (CBDR-RC), as enshrined in the United Nations Framework Convention on Climate Change (UNFCCC). Developed countries have to take lead in reducing their GHG emissions and by providing finance, technology and capacity building support to developing countries. The continuous increase in the global mean-surface temperature due to increasing concentrations of greenhouse gases in the atmosphere, and the noticeable adverse impact of global warming across the world, have resulted in high incidences of disasters and vulnerability of human beings. In this context, the manuscript describes India's updated Intended Nationally Determined Contribution (INDC) targets submitted to the United Nations Framework Convention on Climate Change (UNFCCC) in August 2022, and provides a detailed analysis of the progress made so far to reduce global warming and the major concerning issues. It provides an in-depth analysis of the achievements vis-à-vis the more inclusive global Environmental Performance Index (EPI) ranking 2024 from the overall environmental scenario. The way forward has been suggested based on the policy analysis of climate change and personal opinion. It concludes that though India has done remarkably well in achieving its Nationally Determined Contribution (NDC) targets in containing and mitigating the rise of greenhouse gases, it also requires to address the root cause of the problem such as high population along with the other social issues such as lack of awareness, public participation, and environmental responsibility for improvement in global ranking from the overall environmental perspective.
