The document outlines the environmental and economic dangers of expanding liquefied natural gas (LNG) infrastructure. It highlights that the LNG process is energy-intensive and prone to methane leaks, with US-sourced LNG potentially having a carbon footprint 28% higher than coal. Financially, the report warns of severe overcapacity in Europe, where import capacity may reach 400 billion m3 by 2030 despite a projected demand of only 150-190 billion m3, leading to a high risk of stranded assets in countries such as France, Germany, and Italy. It concludes that conversion to hydrogen or biomethane is largely technically and economically unfeasible, urging financial actors to cease all support for gas expansion.

The W-Fuel project investigated the feasibility of producing biomethane from locally sourced biodegradable waste, sludge, manure, and energy crops in northern Estonia. The study focused on two pilot sites: the Hinnu pig farm in Harju County and a proposed plant in Rakvere, Lääne-Viru County. Findings indicate that while CHP production may be more commercially profitable due to existing feed-in tariffs, upgrading biogas to biomethane for transport fuel is more socially and environmentally beneficial, particularly when accounting for the EU Emissions Trading Scheme (EU-ETS). The report also provides detailed biomass availability forecasts for 2020 and recommends specific waste prevention measures and governmental support schemes to facilitate the transition to gaseous renewable fuels.

The report outlines a pathway for Lao PDR to reach net zero emissions by 2050, utilizing LEAP and NEMO modelling to compare a Baseline Scenario with a transformative Net Zero Scenario. Key findings highlight the necessity of diversifying the energy mix beyond hydropower, electrifying transport and cooking, and implementing carbon removal technologies. The analysis emphasizes that while hydropower remains dominant, the country must scale up solar, wind, and biomass to ensure resilience against climate-induced droughts. Achieving the target requires significant infrastructure upgrades, including grid modernization and the deployment of direct air capture (DAC) to offset residual industrial and agricultural emissions. The report also addresses critical economic challenges, such as high public debt and currency depreciation, and recommends strengthening regional cooperation through the ASEAN Power Grid and the APAEC framework.

The document examines the use of waste-derived Renewable Natural Gas (RNG) in the United States as a means for businesses, states, and municipalities to utilize waste-derived methane and lower the carbon footprint of vehicle fleets. It specifically explores the conditions necessary for RNG to achieve significant greenhouse gas (GHG) emissions reductions relative to fossil fuels.

The briefing outlines potential U.S.-China collaborations to mitigate methane emissions, highlighting research and development in enteric fermentation and rice cultivation, knowledge sharing on biodigesters and remote sensing, and the application of economic and regulatory incentives. It emphasizes the role of subnational engagement, particularly through California, while noting that trade tensions and intellectual property concerns may impede progress.

The report argues that large-scale US dairies can reach net zero emissions within five years by integrating specific technologies and practices, potentially increasing annual net returns to $1.9 million per dairy. Key strategies include precision agriculture, feed additives to reduce enteric methane, and anaerobic digesters that convert manure and organic substrates into renewable energy and fertilizers. The analysis emphasizes that while technologies exist, achieving these goals requires significant policy shifts, such as expanded water quality trading markets and improved EPA processing of renewable fuel pathways.
