Good metrics are a necessity for reducing carbon dioxide emissions from stationary sources. "Good" means everyone uses an agreed-to baseline year, to which all changes are compared, uniform methods for estimating emissions, and validation by third parties. With good metrics, plans for reduction, regardless of whether they are voluntary or mandatory, will be of higher value. The Climate Registry meets all these prerequisites. That's why the Climate Registry's newly increased scope is important. "Led by California, 31 states representing more than 70% of the U.S. population announced Tuesday that they would measure and jointly track greenhouse gas emissions by major industries…State officials, along with some industrial groups and environmentalists, say the registry is a crucial precursor to both mandatory and market-based regulation of industrial gases that contribute to warming. All agree that the most important part of the new registry is subjecting emissions statistics to third-party verification — unlike a Bush administration program that does not require verification…California registry officials worked closely with New England states to develop the system. The new registry will be based in Washington, D.C., and will have regional offices. It will begin tracking data in January. Two Canadian provinces, British Columbia and Manitoba, also have signed on." Reminds us of the internet. Data flows automatically route around damaged servers. Via Los Angeles Times.
