Arizona, British Columbia, California, Manitoba, Montana, New Mexico, Ontario, Oregon, Quebec, Utah, and Washington are the partner-members of the Western Climate Initiative – an intergovernmental organization that aims to reduce greenhouse gas emissions in the region. The WCI aims to establish an emissions cap-and-trade system. The first phase of the cap-and-trade scheme is set to start in January 2012.
The WCI mandates operators of combustion units using mixed fuels (with both biomass and fossil inputs) or waste-derived fuels to use ASTM D6866 to measure the biogenic fraction of their emissions on a quarterly basis. Knowing the biogenic fraction of their greenhouse gas emissions is important as carbon-neutral CO2 is deductible from greenhouse gas inventories.
The WCI members are set to start mandatory reporting in 2011 for gases emitted in 2010.
