🗞️ Driving the news: The Greenhouse Gas Protocol (GHG Protocol) and the International Organization for Standardization (ISO) are set to combine their corporate carbon accounting standards, marking the largest potential update to global emissions reporting rules in more than a decade
• The collaboration aims to create greater alignment in how companies measure and disclose greenhouse gas emissions across global markets

🔭 The context: Corporate carbon accounting currently relies heavily on the GHG Protocol standards, widely used for measuring Scope 1, 2 and 3 emissions, while ISO provides complementary standards used by companies and regulators worldwide
• The move comes as governments, investors and companies increasingly demand more consistent emissions data for climate reporting, transition planning and regulatory compliance

🌍 Why it matters for the planet: Reliable emissions measurement is a foundation for effective climate action
• More consistent accounting standards can improve the quality of corporate climate disclosures, reduce confusion around emissions claims and help direct investment toward genuine decarbonisation efforts

⏭️ What’s next: Organizations are converging on unified methodologies, with upcoming updates expected to clarify emissions accounting and reporting standards

💬 One quote: “Policy decisions are embedded in carbon accounting.” — Tim Mohin, CEO of the Greenhouse Gas Protocol

📈 One stat: The collaboration represents the first major overhaul of corporate greenhouse gas accounting standards in more than a decade, according to the announcement
