Each tool includes step‑by‑step guidance and emission factors to support accurate GHG inventory development in line with the Protocol’s standards

This guide interprets the Greenhouse Gas Protocol Corporate Standard for U.S. public sector organisations. It provides standardised methods for accounting and reporting greenhouse gas emissions, supports inventory quality, and addresses public sector-specific scenarios such as leased assets, joint operations, and regulatory compliance.

This report outlines a neutral framework for estimating and reporting the greenhouse gas impacts of products, both positive and negative. It advocates the use of consequential methods for decision-making, highlights methodological challenges in attributional approaches, and recommends transparency and completeness in emissions assessments and corporate reporting.

This report outlines standards and procedures for quantifying and reporting greenhouse gas (GHG) reductions from mitigation projects. It provides a framework to estimate baseline emissions, assess additionality, and apply consistent accounting principles. The guide supports transparency, credibility, and harmonisation across project-based GHG initiatives.

This working paper presents a methodology for fossil fuel companies to estimate and disclose potential greenhouse gas emissions from their reserves. It outlines seven steps for calculating emissions, addressing combustion, leakage, and storage factors, with the aim of improving transparency and enabling comparison across companies and alignment with climate targets.

The GHG protocol agricultural guidance provides a framework for agricultural companies to develop greenhouse gas (GHG) inventories aligned with the Corporate Standard. It offers sector-specific methodologies to account for direct and indirect emissions, carbon stock changes, and unique agricultural factors such as land use change and biological processes. The guidance enhances consistency, transparency, and usability of agricultural GHG data for decision-making and reporting.

The report explores how board directors perceive and advance climate action. While most recognise its importance and opportunity, competing priorities and knowledge gaps hinder progress. Local Chapters of the Climate Governance Initiative are shown to support action through resources, training, and peer networks across varied global contexts.
