Tucson Electric Power Co. has become a founding reporting member of The Climate Registry, joining 57 other companies, governments and organizations that have volunteered to share information about greenhouse-gas emissions.

The Climate Registry is a non-profit organization set up to measure and publicly report greenhouse-gas emissions in a "common, accurate and transparent manner consistent across industry sectors and borders," TEP said. Thirty-nine American states, five Canadian provinces, three American Indian tribes, two Mexican states and the District of Columbia founded the organization.

TEP has joined the registry along with Arizona Public Service Co. and the Salt River Project, said Gina McCarthy, chairwoman of The Climate Registry and a Connecticut environmental regulator.

The protocol is based on the internationally recognized measurement standards of the World Resources Institute and World Business Council on Sustainability, TEP said.
