Brazil’s advanced biofuel industry lags far behind the production capacity of its first-generation biofuel industry.

Significant greenhouse gas savings are possible by transitioning from first-generation, food-based biofuels to advanced alternative, non-food based fuels.

This briefing paper discusses key terms related to gas in the context of energy policy and climate change mitigation goals in the European Union. It also proposes a method of categorizing gas sources based on their GHG emissions intensity and illustrates how these categories can be used to refer to gas from different sources.

This study presents the production potential for renewable methane in Belgium in 2050. Belgium is developing the domestic energy and gas infrastructure policies necessary to comply with the recast Renewable Energy Directive (RED II) and its Paris Agreement commitments.

This study presents the production potential for renewable methane in the Netherlands in 2050. The Netherlands is in the process of developing the domestic energy and gas infrastructure policies necessary to comply with both the recast Renewable Energy Directive (RED II) and the country’s Paris Agreement commitments.

Alternative jet fuels (AJFs) are among the few available in-sector approaches to reduce aviation sector emissions. Although the aviation sector has not played a prominent role in fuels policy to date, policymakers are increasingly incorporating aviation fuels into long-term strategies as the road sector is electrified.

Aviation is widely seen as the transport sector that is most difficult to decarbonize. One option to dramatically reduce emissions within the aviation sector is through the use of low-carbon alternative fuels.

Renewable methane could conceivably displace natural gas for use in existing vehicle fleets, reducing greenhouse gas (GHG) emissions as well as emissions of air pollutants like NOx. It is important that policy makers assess the realistic potential for renewable methane.

This working paper discusses the potential of zero-emission technologies to reduce emissions from non-road transport, including aviation, maritime, off-road, and rail.

The aviation sector must confront rapidly increasing greenhouse gas (GHG) emissions and ambitious decarbonization targets. Alternative jet fuels (AJFs) could be route to decarbonizing this sector, though these fuels can vary widely in feedstocks used, cost, and environmental performance.
