The potential for low-carbon renewable methane as a transport fuel in France, Italy, and Spain

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...

Can alternative jet fuels crowd out demand from the road sector?

In the aviation industry’s vision of the future, neatly laid out by the International Civil Aviation Organization, airlines can meet all of their obligations under the Paris Agreement through simple...Proponents of alternative jet fuels often ignore the reality that many other sectors have laid claims to limited bio-resources as part of their own decarbonization strategies

Bioenergy can solve some of our climate problems, but not all of them at once

Bioenergy has become a popular decarbonization strategy—so popular that policy makers and researchers in several sectors are claiming biofuels, bio-electricity, and bio-heat can deliver a large...Bioenergy has become a popular decarbonization strategy to reduce greenhouse gas (GHG) emissions. However, even if bioenergy production is maximized, competition across industry sectors is high.

ICAO’s CORSIA scheme provides a weak nudge for in-sector carbon reductions

The International Civil Aviation Organization (ICAO) has not yet figured out how to decarbonize jet fuels. Under the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA),...ICAO's Carbon Offsetting and Reduction Scheme for International Aviation will probably not provide a meaningful framework to transition to alternative jet fuels.

Is Indonesia finally going in the right direction on palm oil?

For years we have wondered whether Indonesia would continue putting a priority on increasing use of palm-based biodiesel rather than on reducing greenhouse gas emissions and preserving forests and...If the government is really concerned about reducing GHG emissions by increasing use of biofuels, there is still time to make sure it includes sustainability clauses, for the environment and the...
