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

System boundaries (red line) schematic for liquid fuel carbon balance. For biofuels, because biogenic carbon is automatically credited within a product lifecycle, the boundary effectively excludes vehicle end-use CO 2 emissions. DeCicco 2013. Click to enlarge.

DeCicco: Transportation GHG reduction policy should focus upstream on fuel supply rather than downstream on choice of fuels in vehicles

Green Car Congress

John DeCicco at the University of Michigan argues that to reduce transportation sector greenhouse gas emissions, the proper policy focus should be upstream in sectors that provide the fuel, rather than downstream on the choice of fuels in the automobile. In a new working paper, Prof. A parametric analysis by Barter et al.

Discussion Paper Suggests Mechanisms for Addressing Biofuel GHG Emissions Under Cap-and-Trade Schemes; Avoiding the Renewability Shortcut and Moving Toward Carbon Management for All Transportation Fuels

Green Car Congress

Including biofuels under a cap-and-trade scheme could create a more complete carbon management framework for the transportation fuels sector, according to a new peer-reviewed discussion paper by Dr. John DeCicco. Thus, the carbon accounting system under a fossil-based cap alone is incomplete when it comes to biofuels.”.

Univ. of Michigan researcher recommends shifting the basis of fuel carbon regulation from lifecycle analysis to ABC accounting

Green Car Congress

Instead, DeCicco proposes a method using annual basis carbon (ABC) accounting to track the stocks and flows of carbon and other relevant greenhouse gases (GHGs) throughout fuel supply chains. From the perspective of resource economics, it is not obvious that LCA is the right tool for regulation. under the U.S.

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

Green Car Congress

Markey of Massachusetts, both Democrats, built their climate change bill last year in large measure around it. The three lawmakers plan to introduce legislation next month that would apply different carbon controls to individual sectors of the economy instead of setting a national target.
