RELEASE: ISO and GHG Protocol Announce Strategic Partnership to Deliver Unified Global Standards for Greenhouse Gas Emissions Accounting
- A new era begins in carbon accounting as ISO and GHG Protocol agree to harmonize their existing portfolios of GHG standards and to co-develop new standards for GHG emissions measurement and reporting
- Until now, GHG standards have been developed separately with varying scopes and verification guidance. The new ISO–GHG Protocol partnership, announced today, represents a fundamental shift toward integration and co-development, enabling users to rely on a coherent framework and reducing potential confusion in the market
- The partnership will produce a common global language for emissions accounting, which will accelerate progress towards decarbonization
- The development of combined, credible standards for GHG emissions terminology, measurement, and reporting provides a long-awaited, trusted solution for companies, investors, verifiers, auditors and policymakers, and aligns with recent calls for harmonization by both government and companies.
