CA Registry’s Online Tool to Serve as Foundation for Global Greenhouse Gas Register

MILAN, ITALY - The California Climate Action Registry (CA Registry) is building the online greenhouse gas (GHG) reporting application for the World Economic Forum’s Global GHG Register. Announced today at the COP-9 conference on global warming in Milan, Italy, the GHG Register is a global initiative for tracking world-wide corporate GHG emissions. The Global GHG Register will improve the transparency and consistency of international GHG reporting – a critical step in efforts to measure and reduce GHG emissions.

The CA Registry, assisted by CH2M Hill, is developing the technical infrastructure for the GHG Register’s online database and reporting application. The CA Registry’s existing web-based reporting tool, CARROT (Climate Action Registry Reporting Online Tool) serves as the basis for the Global GHG Register. Multi-national corporations will be able to use the Global GHG Register to publicly report world-wide GHG emissions in a consistent format.

“The CA Registry’s CARROT is the ideal foundation for our GHG Register – a clear, usable, dynamic platform,” commented Rick Samans, Director of Global Issues at the World Economic Forum. “It’s a solid registry application already used successfully by major businesses to track and report their GHG emissions.”

Through its work with the Global GHG Register and others, the CA Registry is working to promulgate its tools and high quality GHG accounting standards to provide a comprehensive infrastructure for various GHG management policies. The CA Registry can help governments or other NGOs develop GHG registries for entity-wide emissions tracking. These registries complement Kyoto-type tracking registries by ensuring consistent, transparent and complete reporting of corporate emissions data.

“Inventory registries are key tools for effective GHG management policies and are a analytical tool that can support various types of trading regimes,” says Diane Wittenberg, President of the CA Climate Action Registry. “We are committed to sharing our tools and standards with other organizations engaged in GHG disclosure and reporting.”

The CA Registry will continue to upgrade and expand its GHG reporting tools and standards to support international consistency as well as meaningful participation by all industry sectors.


The California Climate Action Registry (CA Registry) is a voluntary GHG registry that accepts California and U.S. annual entity-wide emissions and emissions reductions. The CA Registry’s 40+ members include major corporations, government agencies and NGOs. The State of California commits to use its best efforts to ensure that organizations that register emissions results with the CA Registry receive appropriate consideration under any future regulatory scheme.
