Bioenergy production would boom and spur steep reductions in greenhouse gas emissions if a global price is slapped on carbon, Massachusetts Institute of Technology researchers say in a report released.
The paper raises several questions that need to be faced while further developing subsidy rules in the World Trade Organization. Its primary focus is on whether the shift in the distribution of agricultural subsidies has changed the relevance of the AoA.
Carbon-based liquid fuels are highly valued for transportation; they are the world's largest form of commercial energy and second largest source of anthropogenic carbon dioxide (CO2) emissions. Strategies to address their CO2 emissions have been shaped by fuel cycle analysis (FCA), a version of lifecycle assessment that examines fuel products and their supply chains. FCA studies have diverse findings and large uncertainties. Disagreements are particularly sharp for biofuels, which are seen as key replacements for petroleum fuels.
This paper shows that any dedicated use of land for growing bioenergy inherently comes at the cost of not using that land for growing food or animal feed, or for storing carbon. It recommends several policy changes to phase out forms of bioenergy that use crops or that otherwise make dedicated use of land.
What is second-generation biofuel technology worth to global society? A dynamic, computable partial equilibrium model (called FABLE) is used to assess changes in global land use for crops, livestock, biofuels, forestry, and environmental services, as well as greenhouse gas emissions, with and without second-generation biofuels technology.

Depletion of fossil fuels at an alarming rate coupled with ever growing challenges due to anthropogenic induced climate change stress has attracted increasing attention to blending bio-fuels worldwide. India's primary energy use is projected to expand massively to deliver a sustained GDP growth rate of 9per cent through 2031-32.
Emissions of gases and particles from the combustion of fossil fuels and biofuels in Africa are expected to increase significantly in the near future due to the rapid growth of African cities and megacities. There is currently no regional emissions inventory that provides estimates of anthropogenic combustion for the African continent. This work provides a quantification of the evolution of African combustion emissions from 2005 to 2030, using a bottom-up method.
