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.

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 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 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.

The Global Protocol for Community-Scale Greenhouse Gas Inventories (Version 1.1) provides a standardised framework for cities to measure and report greenhouse gas emissions. It enables consistent, transparent accounting across six sectors, including energy, transport, and waste, supporting emissions tracking, target setting, and aggregation with national inventories.

The Greenhouse Gas Protocol Corporate Standard provides a framework for businesses to quantify and report greenhouse gas emissions. It establishes standardised accounting principles, categorises emissions by scope, and offers guidance for setting organisational and operational boundaries. The Standard promotes transparency, consistency, and comparability in corporate GHG inventories.

This report outlines RIAA’s policy platform to strengthen sustainable finance in Aotearoa New Zealand. It recommends a national strategy, clearer ESG disclosures, taxonomy alignment with global standards, anti-greenwashing measures, Māori inclusion, human rights protections, and alignment with biodiversity and the Sustainable Development Goals.

The Corporate Value Chain (Scope 3) Accounting and Reporting Standard provides a consistent framework for measuring and reporting indirect greenhouse gas (GHG) emissions across a company’s value chain. It outlines 15 categories of Scope 3 emissions, offers guidance on boundary setting, data collection, and reporting, and aims to improve transparency, enable emissions reduction, and support strategic decision-making.

This report assesses cost-effective methods to reduce methane emissions from enteric fermentation, manure management, and rice cultivation. It outlines region-specific strategies and underscores the need for research, regulatory frameworks, and cross-sector collaboration to support implementation and scale-up of mitigation solutions.
