This policy brief by RMI outlines five strategic areas for action to decarbonize the ammonia fertilizer supply chain in Brazil, aiming to transition the country from a fertilizer importer to a global leader in sustainable production.

This working paper, based on a 2023 study by the Stockholm Environment Institute and others, evaluates four decarbonization scenarios for the gas sectors of Estonia, Latvia, Lithuania, and Finland. The analysis focuses on transitioning from fossil gas to renewable methane and hydrogen to enhance energy security and meet 2050 EU sustainability goals, projecting a regional gas demand reduction from 63 TWh in 2021 to 38 TWh by 2050.

This executive summary, based on a report by Aeby et al. (2023), analyzes four decarbonization pathways for the gas sectors of Estonia, Latvia, Lithuania, and Finland to achieve full decarbonization by 2050. The study evaluates scenarios including Business-as-Usual (BAU), Renewable Methane (REN-Methane), Renewable Hydrogen (REN-Hydrogen), and a Cost-Minimizing (CM) scenario, emphasizing the need for regional coordination to reduce dependence on Russian gas and meet EU sustainability goals.

This report, published by the Stockholm Environment Institute in June 2024, examines pathways for the complete decarbonisation of the gas markets in Estonia, Latvia, Lithuania, and Finland by 2050. Based on a study conducted between 2022 and 2023, it evaluates four scenarios—Business as Usual (BAU), Renewable Methane, Renewable Hydrogen, and Cost-Minimising (CM)—to determine the most sustainable and economically viable transition from fossil fuels to renewable gases like biomethane and hydrogen.

This briefing by Zero Carbon Analytics evaluates the role of biogas and biomethane in the energy transition, arguing that their use should be limited to hard-to-abate sectors. The document highlights that biogas only addresses a minority of agricultural emissions, faces significant economic challenges requiring subsidies, and carries risks related to fugitive emissions and safety.

This policy brief by RMI argues that low-carbon fuels—specifically green hydrogen, biomethane, and synthetic methane—are impractical for heating buildings in New York State. The document contends that these alternatives are energy-inefficient compared to heat pumps, require costly and risky infrastructure upgrades, pose health hazards, and divert critical resources away from energy efficiency and electrification goals mandated by the Climate Leadership and Community Protection Act (CLCPA).

This guidance document from the World Resources Institute provides state policymakers with a framework for evaluating the use of Renewable Natural Gas (RNG)—also referred to as biomethane or upgraded biogas—as a tool for meeting climate, waste management, and sustainability objectives.

This report, produced as part of the "From Waste to Traffic Fuel" (W-Fuel) project, analyzes the potential for biogas production and its use as motor fuel in Harju County, Estonia. It evaluates biomass resources, proposes a pilot biogas plant at the Hinnu pig farm, and compares the environmental and economic impacts of using biogas for combined heat and power (CHP) versus upgrading it to biomethane for transport fuel.

This report, produced as part of the 'From Waste to Traffic Fuel' (W-Fuel) project, evaluates the potential for biogas production and its use as motor fuel in Lääne-Viru County, Estonia. It analyzes biomass resources, proposes a pilot biogas plant in Rakvere, and compares the environmental and economic impacts of using biogas for combined heat and power (CHP) versus upgrading it to biomethane for transport.

This report details the 'From Waste to Traffic Fuel' (W-Fuel) project, which investigated the sustainable production of biogas and its upgrading to biomethane for use as transport fuel in two Estonian counties: Harju and Lääne-Viru. The study compared the environmental and economic impacts of using biogas for combined heat and power (CHP) versus upgrading it to vehicle fuel, while also proposing waste prevention strategies for biowaste and sludge.
