Fostering local seasonality: An extended value-belief-norm model to understand sustainable food choices.

As the entire global food system accounts for a significant share of total global greenhouse gas emissions, shifting towards diets that are both environmentally sustainable and healthy has become crucial. By prioritizing local and seasonal foods individuals and communities can help to reduce the environmental impact of their food choices, while also supporting local producers and economies. Psychosocial literature has already shown that Value-Belief-Norm Theory (VBN) is a solid theoretical framework to understand and predict healthy and sustainable food choices. Moreover, other studies have taken into account the additional role of green eating self-efficacy (at home and university) and green self-identity. In light of this, the present study aimed at testing an extended VBN to understand university students’ intention to consume local and seasonal food. 310 university students (age: 18–38; M = 24.18; SD = 3.83; 86.3% females) have completed a self-report questionnaire to assess the variables being studied. Results from a Structural Equation Modeling (SEM) confirmed the majority of proposed hypotheses. More specifically, intention was significantly predicted by green eating self-efficacy at home and moral norms, which, in turn, was directly impacted by ascription of responsibilities, green self-identity and awareness of consequences. Also the causal chain of VBN was confirmed, as well as the direct impact of biospheric values on self-identity. Overall, the abovementioned findings could inform future interventions aimed at promoting more sustainable food choices among university students.

Circular Economy as an Important Lever to Reduce Greenhouse Gas Emissions: Case of an Electricity Distribution Company in Morocco

This article discusses the major challenges related to greenhouse gas (GHG) emissions in the electricity sector and their impact on global climate change. The electricity sector is responsible for about a quarter of total global GHG emissions. To address these challenges, Life Cycle Assessment (LCA) is used to measure the environmental impact of different energy sources and electricity generation and distribution processes. The circular economy is presented as a promising approach to reducing the carbon footprint of the electricity sector. By optimizing the use and value of materials throughout their life cycle, this approach contributes to waste minimization and resource efficiency. Morocco is committed to reducing its GHG emissions and has adopted policies and regulatory frameworks to combat climate change. This study aims to calculate the climate change impacts of electricity distribution phases by applying a life-cycle approach to the case of an electricity distribution company in Morocco. This assessment makes it possible to identify significant contributors from each area. In the context of this company, it is a question of demonstrating how the application of the principles of the circular economy concepts contributes to the reduction of greenhouse gas emissions, in particular, that of scope 3. This study may be useful for other similar companies.

Greenhouse gas emissions trends and drivers insights from the domestic aviation in Thailand

Domestic aviation is a swiftly expanding contributor to global greenhouse gas (GHG) emissions. Presently, economic volatility and the Coronavirus disease (COVID-19) crisis have resulted in the decline of domestic aviation, but domestic aviation is rapidly recovering in many countries. However, from a GHG emissions viewpoint, the domestic aviation sector is largely unenforced even though the International Civil Aviation Organization's (ICAO) Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) provision for international aviation is currently in place. Accordingly, the knowledge base on emissions and their drivers from domestic aviation is weak, especially in developing countries, thus hindering an evidence-based policy debate. In this context, we have estimated and analyzed the pre-COVID-19 GHG emissions and their trends from commercial domestic aviation in Thailand; and provided insights on the role of key drivers that influence GHG emissions that are expected to be useful not only for Thailand but also for other developing countries. Emissions are estimated following Intergovernmental Panel on Climate Change (IPCC) Tier-II. Specifically, activity-based landing/take-off (LTO) cycle and cruise. This is compared to the Tier-I method, and key drivers were analyzed using an index decomposition method. The total annual average GHG emissions for all LTO cycles and cruises of commercial domestic aviation for 2015–2020 was 2254 Th. tonnes of CO2-eq. During the LTO cycle of the aircraft, GHG emissions were at an average of 983 Th. tonnes of CO2-eq. Additionally, during the cruise stage, emissions averaged 1270 Th. tonnes of CO2-eq. The choice of accounting methods (i.e., IPCC Tier II vs. Tier I) seems to have had only nominal implications. Our analysis showed that, in the 2008–2020 period, the aviation activity effect and economic growth were the key decisive factors in this sector's GHG emissions growth. It was followed by the fuel energy intensity levels and the population effect in descending order of impact. These findings have significant ramifications for present and future policies aimed at decreasing GHG emissions, aiding Thailand in achieving its climate targets by 2050, and enhancing energy efficiency as the domestic aviation market adapts.

Willingness to pay for climate change mitigation measures in households: Bundling up renewable energy, energy efficiency, and renovation

AbstractThrough their consumption behavior, households are responsible for more than 70% of total global greenhouse gas emissions. Therefore, the GHG emission reduction potential due to the household behavior is very high. Energy consumption is the main source of the GHG emission in households. There are two main ways to reduce GHG emissions in households: use of renewable energy, energy efficiency improvement, and energy conservation due to changes in the energy use patterns. The highest energy saving potential in households is linked with building renovation, followed by the use of energy efficient appliances (including lighting). Renewable energy microgeneration technologies in households also provide opportunities for GHG emission reduction. Although there have been many policies developed to reduce GHG emissions from energy consumption in households, they still need to be more effective. This paper aims to assess willingness of Lithuanian households to reduce GHG emissions from energy consumption in households by embarking on energy renovation of buildings, use of energy efficient appliances and use of renewable energy technologies. The willingness to pay for these GHG emission reduction measures allows to compare household preferences with respect to available support measures and assess the adequacy of such measures. The paper also discusses household attitudes toward the main policies and measures for GHG emission reduction. The results show the highest willingness to pay for energy efficient appliances, followed by renewable energy technologies. The willingness to pay for energy renovation is the lowest one and such s measure requires significant state support.

A Comparative Techno-Economic Assessment of Alternative Fuels in SOFC Systems for Cruise Ships

Maritime transportation accounts for about 2.9% of global greenhouse gas (GHG) emissions, according to the fourth International Maritime Organization (IMO) GHG study. In the period from 2012 to 2018, shipping emissions have increased by almost 10%. Facing growing political and societal pressure, the IMO has established GHG emissions reduction targets consistent with the Paris Agreement temperature goals, aiming to reduce the total annual GHG emissions by at least 50% by 2050 compared to 2008 levels. In this context, alternative fuels and innovative technologies are needed to allow the maritime industry to comply with forthcoming regulations, as well as to fulfil decarbonisation targets within the European and the global markets.The shipping industry has already started to transition from traditional marine fuels, such as heavy fuel oil and marine diesel oil, to Liquified Natural Gas (LNG) in Internal Combustion Engines (ICEs). However, this can only be regarded as a bridging solution. In recent years, three major research lines can be identified: First, battery-electric propulsion, exploring the potential benefits of shaving peak thruster power and improving the energy efficiency and range of ships. Second, Solid Oxide Fuel Cells (SOFCs), which have a marked advantage of fuel flexibility and offer higher electrical efficiencies than ICEs and other fuel cell technologies, as well as higher-grade waste heat. Third, alternative marine fuels, such as synthetic hydrocarbons, biofuels, ammonia and hydrogen, as a way to significantly reduce or even phase out GHG emissions and other air pollutants.The present study bridges the aforementioned research lines by proposing a novel integrated marine energy system composed of an SOFC-battery hybrid genset that consumes LNG. The objective is to perform a techno-economic assessment of the hybrid genset for LNG and four identified potential alternative fuels (i.e. methanol, diesel, ammonia, and hydrogen). The best solutions will be identified and analysed, and a decision-making framework will be proposed. The comparison will identify the critical conditions for the genset processes being competitive to the state-of-the-art engine-based energy system.The analysis is divided into two main parts. The first part is dedicated to the SOFC module, which is composed of the SOFC stack and the balance of plant equipment. The BOP includes fuel storage, reformer, combustor, heat recovery system, pumps, and blowers. Previous work by the authors has developed the thermodynamic analysis of the genset systems that provide the starting point for the present analysis. The flow-sheet software Cycle Tempo was used in those analyses. The SOFC module has a nominal power production of 100 kWe, which is achieved by combining several stacks of 10 kWe, and produces hot water at 90 °C and saturated steam at 180 °C from waste heat recovery.In the second part, the SOFC-battery hybrid genset is achieved by combining several 100 kWe SOFC modules into power blocks and hybridizing them with batteries. The systems are designed to cover all the electricity and heat demands of the vessel, including propulsion and hotel load. A representative electrical demand of a large cruise ship is selected in the range of 30-60 MWe, of which about 80% is required for propulsion while the remaining is needed for the hotel.Among the main criteria for comparing the hybrid genset running on different fuels are the total annual cost, composed of the annual investment cost and annual operation cost, and the Levelized Costs of Energy, Electricity and Exergy. The latter is especially important because of the joint production of electricity and heat (saturated steam at 180 °C and hot water at 90 °C) that takes place in the genset. The investment cost was estimated using data collected from the literature or provided by manufacturers. The necessary replacement of SOFC stacks is taken into account, given the stack lifetime. Weight and volume requirements associated with the use of different fuels are assessed. The annual operation cost consists of fuel consumption and maintenance costs, as well as the application of an environmental tax for CO2 emissions.Different scenarios are proposed to evaluate the impacts of improvements in key parameters on the overall feasibility of the systems. The robustness of the results is evaluated by sensitivity and uncertainty analyses of the key technical and economic parameters used in the model, including, among other parameters, the fuel purchase price, SOFC and battery investment costs, stack lifetime, and interest rate. This research provides a systematic comparison of the techno-economic feasibility of five alternative fuels for cruise ships. The results will aid decision-makers, including shipyards and policymakers, in designing new energy systems with low emissions for maritime applications.

Environmental Sustainability Analysis Using Moderation of Transport Competitiveness for Industrial-Induced EKC

Combating adversities of climate change and promoting clean energy are two important goals of the Sustainable Development Goals (SDGs). The nations of the World have developed various commitments to reduce global warming. The transportation sector share is above twenty percent in total global Greenhouse Gas emissions which is continuously rising over time. The Intergovernmental Panel on Climate Change (IPCC) in its recent report conducted a scenario analysis and suggested reducing net emissions by 2050. The transport competitiveness index indicates the quality and expansion of transport services. Accordingly, this research study uses the data of 121 countries for which transport competitiveness is documented by the World Economic Forum (WEF). The period of the study is confined to 2008-2018. The sample countries are segregated into four groups on the basis of transport sector emissions. The study uses Panel Quantile Regression (PQR) framework to estimate results and to validate the industrial Environmental Kuznets Curve (EKC). The findings indicate that transport competitiveness mitigates transport sector emissions in the majority of groups/categories. Inverted U shape industrial EKC has been authenticated in group-1 and U shape industrial EKC for the other three groups. The moderation of transportation competitiveness specified the flattening of industrial EKC across all quantile groups. The empirical findings indicate that moderation results in the sustainability of industrial EKC at higher levels of industrial growth. Among other variables, the governing ability of institutions and planned population expansion are observed in mitigating emissions. The policy options are discussed depending on the results of the groups.

Food Waste

This research project explored solutions for food waste reduction and mitigation across Te Whatu Ora / New Zealand Public Hospital systems by looking at the case study of Dunedin Public Hospital. Directly relating and supporting Sustainable Development Goal (SDG) 12.3, to halve global food waste at consumer and retail levels by 2030. This research was done by analysing appropriate literature exploring food and organic waste management strategies in national and international hospital service sectors and systems, further using the Food Recovery Hierarchy as a framework, which ranks the effects of these strategies when looking at them financially, environmentally and socially. Furthermore, this research looks at the barriers and enablers of the suggested organic waste management strategies. A food waste audit was conducted at Dunedin Public Hospital to assess and quantify the current organic waste within the system. The key questions of this study are: How do we prevent organic waste in the first place (preparation strategies)? What can we do with the organic waste produced to prevent it from going to landfills? What items in the food system are the most wasted? How much Greenhouse gas (GHG) is produced by this organic waste going to landfill? Organic waste produces methane, occupies land mass and has the potential for groundwater contamination. Ten per cent of total global GHG Emissions come from food waste, 22% of which is occurring at the consumption level. The key impact of this research is to mitigate organic waste going to landfills to reduce further climate change, thus benefiting environmentally, socially and economically.

Identification of economic incentives for the electrification of river and maritime modes: proposal for the Colombian Case

The transportation sector's significant contribution to greenhouse gas (GHG) emissions, primarily through fossil fuel consumption by motorized vehicles, remains a critical concern. In this industry, maritime transportation independently contributes to 2.89% of total global greenhouse gas emissions, displaying a persistent upward trend even in the face of enhanced efficiency measures implemented in port facilities and vessel operations. In response to this urgent concern, nations and international organizations have been formulating approaches aimed at mitigating greenhouse gas emissions in this transportation sector, encompassing the implementation of economic incentives. This article presents the findings of an exploratory-descriptive research endeavor, which aims to identify incentive policies implemented across various countries to expedite the adoption of electromobility in maritime and river transportation, thereby reducing GHG emissions from vessels. Data was gathered from authorized government websites, various organizations, maritime and river transport companies, and port authorities in each respective nation. Furthermore, this study classifies the incentives according to their methodologies and conducts a comparative analysis with the existing landscape in Colombia regarding the adoption of economic incentives for electrifying river transportation within the country. Through this analysis, some insights and recommendations can be derived to promote sustainable and environmentally-friendly practices in Colombia's river and maritime transportation sectors.

Global oil refining's contribution to greenhouse gas emissions from 2000 to 2021

The refining industry is the third-largest source of global greenhouse gas (GHG) emissions from stationary sources, so it is at the forefront of the energy transition and net zero pathways. The dynamics of contributors in this sector such as crucial countries, leading enterprises, and key emission processes are vital to identifying key GHG emitters and supporting targeted emission reduction, yet they are still poorly understood. Here, we established a global sub-refinery GHG emission dataset in a long time series based on life cycle method. Globally, cumulative GHG emissions from refineries reached approximately 34.1 gigatons (Gt) in the period 2000-2021 with an average annual increasing rate of 0.7%, dominated by the United States, EU27&UK, and China. In 2021, the top 20 countries with the largest GHG emissions of oil refining accounted for 83.9% of global emissions from refineries, compared with 79.5% in 2000. Moreover, over the past two decades, 53.9-57.0% of total GHG emissions came from the top 20 oil refining enterprises with the largest GHG emissions in 12 of these 20 countries. Retiring or installing mitigation technologies in the top 20% of refineries with the largest GHG emissions and refineries with GHG emissions of more than 0.1 Gt will reduce the level of GHG emissions by 38.0%-100.0% in these enterprises. Specifically, low-carbon technologies installed on furnaces and boilers as well as steam methane reforming will enable substantial GHG mitigation of more than 54.0% at the refining unit level. Therefore, our results suggest that policies targeting a relatively small number of super-emission contributors could significantly reduce GHG emissions from global oil refining.

Cementless building materials made from recycled plastic and sand/glass: a review and road map for the future

Plastic and glass can be sorted using machines and recycled into new plastic and glass, as opposed to producing them from raw materials. However, contaminated plastic and glass, as well as certain types of plastic and glass, cannot be recycled using traditional methods and must be disposed of in landfill. Researchers have been looking into this and have tried a variety of solutions to convert this waste into functional products. The development of composite construction materials, based on these two materials was identified as a worthy solution. On the other hand, carbon dioxide is emitted during the cement manufacturing process and the use of that cement in the production of construction materials contributes 7% of total global greenhouse gas emissions. Hence, plastic sand/glass composite is environmentally friendly in two ways. It reduces landfill while also replacing the equivalent concrete product, lowering CO2 emissions. This paper examines the literature on the development of such materials, including technology, challenges, quality, and properties. At the raw material selection stage, the effect of sand grain sizes, gradation, plastic type, plastic mix, impurities, pre-processing, and cleaning was investigated. At the material processing stage, the filler to binder ratio, mixing temperatures, mixing methodology, and compaction were all examined. It was identified plastic type and a mix of plastic, as well as impurities did not affect the density or strength of the composite significantly. Also, the compressive strength of the composite products manufactured in the considered studies is comparable to C20/25 concrete.

Hydrogen Storage in Offshore Salt Caverns for Reducing Ships Carbon Dioxide Footprint

Global shipping activity emits significant amounts of GHG (Greenhouse Gas) emissions, estimated to be around 2-3% of total global GHG emissions. Studies have been made for hydrogen refuelling hubs in the Pacific area, for container ships, that are the worst polluting sources in the oceans. The present paper will show an idea for creating such refuelling hubs using salt cavern for hydrogen storage in Black Sea, and also in other offshore places where the geological formations allow it. The study will allow also the using of hydrogen in military purposes for refuelling the coastal patrol ships or tactical warships like Romanian frigates.

Separation of Azeotropic Refrigerant Mixtures Using Ionic Liquids

Refrigeration and air-conditioning systems are widespread throughout modern society, from the refrigerated cold chain that provides fresh foods and storage of medicines to the air conditioning of homes and buildings. Refrigeration is viewed as one of the most transformative engineering achievements of the 20th century and the demand for cooling will continue to increase as economic conditions improve and the climate continues to warm; however, refrigerants do come with an environmental cost.In 1987, the Montreal Protocol phased out chlorofluorocarbon (CFC) refrigerants because of their high ozone depletion potential (ODP). The replacements, typically mixtures of hydrofluorocarbons (HFCs), are safe for the Earth's ozone layer, but most have high global warming potentials (GWPs). HFCs account for 7.8% of total global greenhouse gas emissions, with 63% of that from “indirect” emissions (i.e., energy for running the system). As a result, 197 countries signed the Kigali agreement in 2016 to phase out high-GWP HFCs, with the goal of reducing emissions by 80% in the next 20 years. Millions of metric tons (mts) of high-GWP refrigerants will need to be reclaimed, but there are no good methods for separating and recycling the individual components, given that many are azeotropic mixtures.Currently, there is no means of separating azeotropic HFC mixtures, and the refrigerants will ultimately have to be incinerated. The commercial HFC mixture R-410A containing 50 wt.% HFC-32 (GWP = 675) and 50 wt.% HFC-125 (GWP = 3500) is a prime example. The HFC-32 can be reused when separated in new low-GWP products such as R-454B (69 wt% HFC-32 and 31 wt% HFO-1234yf) with a 75% lower GWP than R-410A.Ionic liquids are being developed that can separate azeotropic HFC mixtures based on differences in solubility and used as entrainers in extractive distillation. This presentation will provide experimental data on the solubility of HFCs in ionic liquids that have been measured using gravimetric microbalances and modeling using the Peng-Robinson equation of state. ASPEN Plus simulations will show how a pilot process has been designed that can continuously separate azeotropic refrigerant mixtures such as R-410A.

The Role of CSR for De-Carbonization of Hospitality Sector through Employees: A Leadership Perspective

Tourism and hospitality have been recognized as leading economic sectors globally. Before the outbreak of COVID-19, it was estimated that the tourism and hospitality sector was growing by around 4% each year. Although the economic-efficiency-led hypothesis of the tourism and hospitality sector is strong, there is another perspective related to tourism and hospitality. That is, tourism and hospitality are not as “green” as they were supposed to be. Indeed, this sector is known for its outsized carbon footprint. It is estimated that, if not managed efficiently, the GHG contribution of the tourism sector will grow in the future. Specifically, the hotel business accounts for 1% of total global greenhouse gas emissions (GHG), which is huge. Responding to these significant issues, this study investigates the relationship between the corporate social responsibility (CSR) activities of a hotel enterprise and employees’ pro-environmental behavior (PEB). The mediating role of environmental-specific transformational leadership (ESTFL) and the moderating role of green perceived organizational support (GPOS) were also tested in the above relationship. The data were collected by the employees through a self-administered questionnaire. The hypothesized relations were statistically investigated by using structural equation modeling (SEM). The findings revealed that CSR activities of a hotel not only influence employees’ PEB directly, but the mediating role of ESTFL was also significant. At the same time, the conditional indirect role of GPOS was also confirmed. This study offers different theoretical and practical insights, which have been discussed in detail.

Optimal Configuration of a Negative Carbon Emission Energy System for Green Agriculture

Agriculture has been the second largest emission sources, contributing to 23% of total global greenhouse gas emissions. Direct air capture (DAC) technology can capture CO2 in decentralized carbon emission sources, which is suitable for the development of a negative energy system to compensate for the emissions generated from agriculture. For this reason, this paper presents a DAC-based green agriculture energy system consisting of DAC, wind power, solar power, battery energy storage system and electrical boiler to meet the negative carbon reduction energy supply requirement for agricultural area. Dry reforming methane and microalgae planting technologies are also deployed to fully utilize the captured CO2. To better coordinate the multiple energy generation, conversion, consumption and storage devices within the green agricultural energy system, a capacity configuration optimization method considering the objective of minimizing the total investment and operating costs is proposed. This paper takes a 150 hm2 agricultural area located in Nanjing, China into consideration, which has a carbon emission intensity of 2,007.5 kg/hm2. The case study showed that, the proposed energy system can obtain the most economic equipment capacities while achieving the goal of annual negative carbon emission at the expenses of $1.17 million annual initial investment and $60 thousand operation costs.

Особенности развития возобновляемой энергетики в Республике Бурятия и Монголии

Every year, humanity is increasingly faced with a shortage of electricity on the one hand, and with an increase in greenhouse gas emissions after the generation of electricity at thermal power plants (TPPs), on the other. Energy is the dominant driver of climate change and accounts for about 60 percent of total global greenhouse gas emissions. The article is devoted to the analysis of renewable energy development in the Republic of Buryatia and Mongolia over the past 10 years. The constantly growing demand for electricity and relatively small energy capacities are forcing the Republic of Buryatia (to a greater extent) and Mongolia, which are limited in some types of economic activity, to look for new sources of energy. One of these restrictions is the ban on the construction of hydroelectric power plants on the rivers of the Baikal Lake basin. Therefore, Buryatia and Mongolia have embarked on the path of building environmentally friendly power plants and have succeeded in many ways. In last years, in connection with the UN Sustainable Development Goals on the development of infrastructure for the provision of affordable and clean energy (Goal 7), there has been a need to develop renewable energy sources. One of the priority areas for the development of renewable, including alternative, energy in Buryatia and Mongolia is solar, wind, hydro and geothermal energy. UN Sustainable Development Goal 7 aims to ensure universal access to affordable, reliable, sustainable, and modern energy for all. As part of the implementation of the UN Sustainable Development Goal 7, solar and wind power plants have been actively built in Buryatia and Mongolia over the past 10 years. Despite the high costs of their creation, the contribution to alternative energy is a long-term and profitable investment in infrastructure. At least investors (including foreign ones) investing in a seemingly lowprofit project look far into the future. Smart investors do not run after «quick money», realizing that the constructed power plants will pay off for a long time, since at the moment of development they have a relatively low efficiency. Despite the criticism, they are investing in green energy, modern infrastructure, and a future without emissions (CO2, NO2, SO2 and other Greenhouse gases) from burning coal, fuel oil and firewood. For the qualitative development of the economy, it is necessary, first of all, a balanced development of generating and network capacities, therefore, it is possible to solve the problem of shortage of electricity without a heavy burden on the environment only by developing alternative energy (renewable energy sources).

Carbon Farming: Prospects and Challenges

Carbon farming is a capable strategy for more sustainable production of food and other related products. It seeks to produce a diverse array of natural farming methods and marketable products simultaneously. According to the food and agriculture organization (FAO), agriculture, forestry, and other land-use practices account for 24% of global greenhouse gas (GHG) emissions and total global livestock emissions of 7.1 gigatons of CO2-equivalent per year, representing 14.5% of total anthropogenic GHG emissions. For example, an agroforestry system that deliberately integrates trees and crops with livestock in agricultural production could potentially increase carbon sequestration and decrease GHG emissions from terrestrial ecosystems, thus helping to mitigate global climatic change. Also, agroforestry is capable of generating huge amounts of bio-mass and is believed to be particularly suitable for replenishing soil organic carbon (SOC). SOC is a crucial indicator for soil fertility since the change in SOC can explain whether the land use pattern degrades or improves soil fertility. Moreover, SOC found in soil in the form of soil organic matter (SOM) helps to improve soil health either directly or indirectly. Thus, efforts should be made to convince farmers to increase their resource-use efficiency and soil conserving ability to get maximum benefits from agriculture. Therefore, this review aimed at clarification about carbon farming, modifications in carbon cycle and carbon sequestration during agricultural development, and benefits of agroforestry.

Review and estimation of global halocarbon emissions in the buildings sector

Estimates of the non-CO2 greenhouse gas (GHG) emissions contributed by the buildings sector are necessary to evaluate this sector’s potential for climate change mitigation. As data is lacking on fluorinated gases (F-gases) and hydrofluorocarbon (HFC) emissions from the buildings sector, this study aimed to estimate these emissions. First, the share of total global GHG emissions represented by buildings-sector emissions was estimated. Then, the HFC emissions of the buildings sectors in several countries (USA, EU, Japan, and China) are compiled. Next, based on necessary assumptions, global buildings-sector HFC emissions were estimated. Finally, this paper discusses implications for policy-makers.

Inventory of main greenhouse gas emissions from energy sector in Palestine.

This paper analyzes the building process of the main greenhouse gas (GHG) emissions (CO2, CH4 and N2O) inventory from the energy sector in Palestine. The paper includes determination tools, i.e., emission factors, to estimate the amounts of national GHG emissions from sub-sectors of energy including energy industries, manufacturing industries and construction, transport and other sectors (households, agriculture and commerce and public services). The results show that the total amount of national GHG emissions from the energy sector in 2016 was 4131 thousand metric tons of CO2-equivalent (TtCO2e), which represented 0.011% of the total global GHG emissions. The average value of GHG emissions per capita from the energy sector was 0.86 tCO2e in Palestine, and its gross domestic product was estimated at 3212$/ton of CO2e. The estimated amounts of CO2, CH4 and N2O emission from the energy sector were 4022, 49 and 60 TtCO2e, respectively. The transport and household sub-sectors dominated the national GHG emissions from the entire energy sector by 58 and 32%, respectively. In general, fuels including diesel, gasoline, wood and charcoal and liquefied petroleum gas made most of the total amount of the national GHG emissions from the energy sector at 50, 18, 18 and 12%, respectively. Finally, the mitigation actions included in the first nationally determined contribution of Palestine and recommendations to help lower the national GHG emissions from the Palestinian energy sector are provided.
