Can a rugged Latin American palm become a major sustainable biofuel source?

June 24, 2016
Bailis, R.

A huge demand has developed for oil for biodiesel and now also for aviation biofuel, but finding a sustainable source has been hard. Oil palm is sturdy and highly productive, but grows best in wet tropical areas, and vast swaths of rainforest have been razed to make way for it. Jatropha also raised hopes, because it can grow in poor soil with minimal inputs, but it turned out not to be as hardy and self-sufficient as initially thought. Now, Acrocomia aculeata, also called macaúba or macaw palm, is gaining attention as a potential sustainable biomass feedstock, particularly for biofuel. A newly published paper says the tree has promise, but also faces significant risks, and more study must be done before attempting commercial cultivation.

Can offsets and biofuels make future international aviation growth ‘carbon-neutral’?

June 8, 2016
Bailis, R. , Broekhoff, D. , Lee, C.M.
An SEI analysis finds significant potential for offsets and, to a lesser extent, alternative jet fuels to reduce emissions, but stresses the importance of high standards and certification to ensure benefits and avoid negative impacts.

Phasing out U.S. federal fossil fuel leases could yield real climate benefits

May 3, 2016
Erickson, P. , Lazarus, M.
U.S. fossil fuel production is at an all-time high, up by 20% in energy terms since 2010. The U.S. now ranks first in the world in oil and gas, and second in coal production. About a quarter of the fuels being extracted, including two-fifths of all coal, come from lands and waters leased to producers by the federal government. A new SEI analysis shows phasing out leases for extraction on federal land could reduce fossil fuel consumption equivalent to more than 100 million tonnes CO2 per year by 2030 – and more in later years.
