Summary: This study evaluated the impact of sustainable water and energy management on greenhouse gas emissions and economic benefits at six small-to-medium airports in the Adriatic region. The results showed that the airports are taking positive steps towards sustainability, with a higher share of natural gas in heating fuel and green electricity tariffs. Efforts to achieve zero-emission airports should focus on decarbonizing motor fuels and improving energy efficiency and clean energy for heating and electricity.

Summary: Transportation is vital for a modern economy, but the increasing energy demand and climate impact require urgent action. Life-cycle analysis is a suitable method for evaluating the greenhouse gas performance and decarbonization potential of transportation fuels and vehicle powertrains. This study assessed the well-to-wheels greenhouse gas emissions reductions for light-duty vehicle fuel and powertrain technologies in the EU and the US, finding that waste-to-fuel technologies and biofuels offer the greatest opportunities for reducing emissions.

Summary: The study showed that the IPWL in China fluctuates geographically, with a trend of being higher in the south and lower in the north. Over time, an increase in IPWL led to fewer provinces inhibiting the impact of IPWL on agricultural CO2e emissions per unit sown area, with this effect weakening in seven provinces. Spatially, higher IPWL in most areas in China corresponds to a higher contribution rate of IPWL to agricultural CO2e emissions per unit sown area.

Summary: This study conducted a well-to-wheels analysis of liquified biomethane (LBM) production chains and found that despite increased emissions from liquefaction, LBM has a negative impact on addressing transport emissions and agricultural waste management. The emissions of nitrous oxides (NOx) from biomethane and fossil fuels are similar, with fuel combustion in the vehicle engine being the main source. The most intensive processes contributing to climate change were biomethane upgrading and liquefaction.

Summary: This study uses country-level technology-rich energy-economy and integrated assessment models to present national low-emission scenarios for Australia, Brazil, Canada, China, EU-28, India, Indonesia, Japan, Republic of Korea, Russia, and the USA. The research shows that most economies studied have low-emission pathways consistent with limiting global temperature increase to well-below 2 degrees C, achieved through uptake of renewable energy, energy efficiency improvements, and electrification of energy services. The role of mitigation options like nuclear, carbon capture and storage (CCS), and advanced biofuels varies across countries based on national priorities, specificities, and resource endowments.

Summary: China has announced its climate goal to peak carbon emissions by 2030 and achieve carbon neutrality by 2060. However, the pathway to decarbonization is unclear and there are significant differences in achieving the carbon-neutral goal, particularly regarding non-fossil fuel energy sources. Near-term policies allowing for gradual transition and drastic changes after 2030 can eventually achieve the carbon-neutral goal.

Summary: Cities play critical roles in achieving carbon-neutrality. The pathways and challenges to carbon-neutrality differ among different city types. The industry sector is always the key sector, and optimizing production processes and reducing surplus output are crucial. Some cities can achieve carbon-neutrality by implementing carbon capture and storage technology by 2049 or 2050. Challenges include reducing CO2 emissions from transportation and buildings, as well as promoting electrification and the use of zero-carbon energy.

Summary: China has rich resources of energy crops and marginal land for bioenergy development. Under future carbon-related policies, bioenergy production is projected to increase significantly and can be fully met by current marginal land by the end of the century. High carbon taxes may increase agricultural market prices but will not affect crop residue production. Additionally, efforts on policy designing to support energy crop cultivation and promote BECCS research and deployment should be intensified to reduce carbon emissions.

Summary: This paper examines the impact of real-time pricing and load automation on residential distribution systems. The study finds that implementing real-time pricing can result in an aggregate welfare gain of 39 USD per customer and year. However, it also notes that RTP and load automation may significantly increase peak system load. Introducing a market-based demand management system can further enhance welfare gains and reduce grid investment.

Summary: Household solid fuel use is detrimental to health and the environment. The Indian government's PMUY subsidy has successfully promoted the adoption of LPG by millions of households. However, there is limited understanding of the decision-making process to reduce solid fuel use after transitioning to cleaner fuels. This study found that factors such as household wealth, social status, education level, and the prevalence of LPG use in the village are positively associated with LPG consumption and the discontinuation of solid fuel use. On the other hand, factors such as distance to LPG refill delivery, household size, and the PMUY subsidy are negatively associated with the share of LPG use.

Summary: Economic costs are a major political obstacle to investing in climate change mitigation and adaptation measures. The method of financing plays a crucial role in determining public opposition to government green investments, with debt financing being less opposed than broad-based taxes. This study suggests that credit market tools, such as green bonds and debt for climate swaps, can be politically efficient in increasing support for green financing. Carbon taxes and wealth taxes are found to be the most preferred options.

Summary: This paper investigates China's energy trade stability using a survival analysis approach. It finds that the energy trade linkages between China and 153 other countries are complex and unstable, with short periods of trade with many countries. Geopolitically risky regions, such as the Middle East and Africa, have the lowest trade stability. Climate risks have significant effects on energy trade stability. The paper proposes several policy options to improve energy trade stability in China, with special attention to increasing global climate risks.

Summary: This study estimates the willingness to pay of Indian urban consumers for a continuous supply of electricity using contingent valuation method. The findings show that the amount consumers are willing to pay depends on the duration of power outages, with households preferring shorter outages. Income and environmental attitude also positively influence higher willingness to pay. These insights can inform policymakers in designing more reliable and customer-centric energy generation and distribution models.

This study investigates the impact of REC purchases on stock return and volume in Taiwan between 2017 and 2021. The findings suggest that REC purchases have a positive effect on stock returns of manufacturing firms but not service firms. The frequency of REC purchases is also an important factor in the relationship between REC purchase and firm value. Additionally, the study reveals that public attention to environmental pollution plays a crucial role in positive stock returns and volume, while ESG disclosure is negatively associated with returns and volume.

Summary: This paper addresses the challenges of governing energy procurement from a mix of non-hydropower renewable energy sources supplied by independent producers. Building on political economy analysis and five case studies of independent producer projects from Ethiopia, it seeks to understand the root causes of the protracted delays and limited extent of procurement by independent producers. The key contestations lie in managing long term contracts, risk, uncertainty and in developing the institutional and human capacity to transition.
