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.

LMI provides advanced logistics, supply chain resilience and analytics solutions for U.S. federal agencies. With more than 60 years of public‑sector expertise, LMI delivers applied artificial intelligence, machine learning, modelling and simulation to enable risk‑informed decisions, optimisation of inventory and fleet sustainment, and rapid technology deployment.

ICLEI – Local Governments for Sustainability (ICLEI) is a global network of 2,500+ cities, towns and regions across 125+ countries. It supports local governments with technical assistance, peer exchange and tools to accelerate climate action, sustainable urban development, biodiversity protection and resilient, equitable and circular outcomes.

This supplemental report provides standardised methods for communities to estimate greenhouse gas emissions and carbon removals from forests and trees. It expands the global protocol for community-scale greenhouse gas inventories by offering detailed guidance for accounting Scope 1 emissions and removals, supporting local climate action planning and integration with national inventories.

These guidelines provide a standardised, policy-neutral framework for quantifying greenhouse gas (GHG) reductions from grid-connected electricity projects. They cover both generation and electricity reduction activities, using simplified methods to estimate baseline emissions and avoided emissions. Intended for project developers and programme designers, the guidelines emphasise accuracy, transparency, and conservativeness.

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.

The greenhouse gas protocol’s land sector and removals initiative aims to develop internationally accepted corporate guidance for accounting and reporting emissions and removals from land use, bioenergy, and carbon removal. It seeks to improve transparency, support target-setting, and align with climate goals through a multi-stakeholder, science-based process.

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 outlines how banks can link technology investments to value creation. It presents a framework to improve returns through strategic allocation, outcome-based execution, and transparency. It identifies five tech-enabled themes that align with shareholder value drivers such as revenue growth, fee income, and risk mitigation.

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.

The land use, land-use change, and forestry (LULUCF) guidance for GHG project accounting provides structured methods to quantify and report greenhouse gas (GHG) reductions from reforestation and forest management projects. It supplements the GHG Protocol for Project Accounting, detailing baseline procedures, monitoring, and risk mitigation approaches specific to land-based carbon projects.

The GHG Protocol Product Life Cycle Accounting and Reporting Standard provides a globally consistent framework for companies to quantify and publicly report greenhouse gas emissions and removals associated with individual products across their life cycle. It enables informed emissions reduction strategies and supports performance tracking, supplier engagement, and product differentiation.

The Policy and Action Standard provides a consistent framework for estimating and reporting the greenhouse gas (GHG) impacts of policies and actions. It outlines methods for ex-ante and ex-post assessments, defines principles of GHG accounting, and offers guidance on defining policy boundaries, estimating baseline emissions, and assessing uncertainty to support transparent, accurate decision-making.

This report outlines a standardised framework for governments to design, assess, and report on greenhouse gas mitigation goals. It defines principles, methodologies, and accounting requirements to support consistent and transparent emissions tracking and goal evaluation at national and subnational levels.
