The Climate Registry

The Climate Registry is a collaborative partnership among states, tribes, and provinces to develop and manage a common greenhouse gas (GHG) emissions reporting system capable of supporting multiple GHG emissions reporting and reduction policies. The Climate Registry will ensure consistency and transparency between climate programs implemented by states, provinces or tribes and establish a high level of environmental integrity in emissions accounting reporting, and verification.

The goals of The Climate Registry are to:

  • Create a common standard for measuring and tracking greenhouse gas emissions. Emitters and policy makers benefit from the standardization of emissions reporting, reduction measurement and the establishment of a common carbon currency.
  • Standardize best practices in greenhouse gas emissions reporting. The WRI/WBCSD GHG Protocol Corporate Standard has already established internationally-recognized standards for greenhouse gas accounting at the entity-level. The Registry operationalizes these standards.
  • Promote full and public disclosure of greenhouse gas emissions. The Registry will ensure that greenhouse gas emissions data is made available to the public through annual reports posted on the Registry's website. The Registry will ensure that sensitive business information remains confidential.
  • Lower policy implementation costs for states, provinces, tribes and Reporters. Highest savings will come from standard measurement and reporting protocols, a common software platform, and centralization of technical expertise and support.
  • Establish a common infrastructure to support current and future mandatory reporting programs. The Registry will develop a greenhouse gas emissions reporting system to help support and link state-mandated greenhouse gas emissions reporting programs.

The Registry is governed by its Members: U.S. and Mexican states, Canadian provinces and Indian tribes. Members have signed the Registry's Statement of Principles and Goals (PDF, 31kb) supporting common greenhouse gas measurement and reporting standards. One Board Member per state, province or tribe serves on the Board of Directors of the Registry. Board Members are appointed by their respective Governors, Premiers, or other governing authority. All U.S. states, Canadian provinces, Mexican states, and Indian tribes are welcome to Become Members of the Registry by signing the Statement of Goals and Principles and submitting it to the Registry. There are currently 40 U. S. states, 9 Canadian Provinces,  6 Mexican states, and 3 native American tribes participating in The Climate Registry. The State of Maine is a founding member of The Climate Registry.
