The California Climate Action Registry will play a growing role now that the California Public Utilities Commission has decided to control greenhouse gas emissions from the state\u2019s power industry. However, the non-profit may be melded into state government as the state program is implemented. \u201cPotentially it means a big increase in our membership,\u201d said Joel Levin, registry vice president. Already, Reliant Energy has joined the registry and additional municipal utilities are expected to announce their membership in the coming weeks. However, the governor\u2019s state climate action team is considering whether the registry should become an official part of the state government, acknowledged Levin. \u201cIt\u2019s their perception we\u2019re government, we\u2019re non-government. Regulation should be done by government,\u201d Levin said. He added that a number of bills are expected to be introduced in the Legislature concerning global warming, which could become vehicles for changing the registry\u2019s status. The Legislature created the registry in 2001 to establish an organization that could develop standardized accounting methods for greenhouse gas emissions. By using these standards and registering their emissions with the organization, the companies will be able to take credit for any emissions reductions required by future regulations. To date, the registry has developed standardized protocols for the power, forestry, and cement industries to track greenhouse gas emissions. It is working on protocols for other industries. The state\u2019s three investor owned utilities already belong to the registry, as do many municipal utilities and a growing list of independent generators. Even out-of-state companies have joined the registry. Levin said the registry is coordinating its standards closely with a similar registry in the Northeast and has been working with groups that want to set up registries in the Midwest and West. He said that by the end of the year, the groups may announce a new system under which companies that operate across state lines could file one single standardized emission report that would be accepted in all of these areas for regulatory purposes.
