U-Mich researcher’s first-principles analysis challenges conventional carbon accounting for biofuels; implications for climate policy

Green Car Congress

For biofuels, because biogenic carbon is automatically credited within a product lifecycle, the boundary effectively excludes vehicle end-use CO 2 emissions. In a paper that could have a significant impact on climate policies for transportation fuels, Dr. John M. System boundaries (red line) schematic for liquid fuel carbon balance.

Perspective: Regional Greenhouse Gas Cap-and-Trade Programs May be the Solution

Green Car Congress

A limit was imposed on emissions from the power plants, and utilities were allowed to buy and sell permits to comply. These reductions in power plant emissions of sulfur dioxide (SO 2 ) and nitrogen oxides (NO x ) were achieved at a significantly lower cost than originally assumed. greenhouse gas emissions.
