This report provides practical guidance for applying the Singapore-Asia Taxonomy (SAT) in green and transition financing. It addresses data gaps, evolving criteria, transition plans, and scenarios where full alignment with SAT is not possible, promoting credible financing practices across Southeast Asia’s key sectors.

This report outlines pathways for mobilising institutional capital towards the Sustainable Development Goals and a Just Transition. It focuses on investment vehicles, emerging markets, and private asset classes, providing practical recommendations, case studies, and frameworks to integrate environmental, social, and community considerations into scalable, impactful financial strategies.

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.

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 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.

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 updates the GHG Protocol Corporate Standard by introducing dual reporting for Scope 2 emissions—requiring both location-based and market-based methods. It defines Scope 2 accounting principles, emission factor hierarchies, and quality criteria for contractual instruments, aiming to improve transparency, accuracy, and comparability across energy markets.

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.

Nuclear energy is gaining momentum as a reliable, low-emissions electricity source. The report outlines growth drivers, investment needs, emerging technologies such as small modular reactors, and policy frameworks required for scale-up. Financing challenges, supply chain risks, and workforce planning are key to realising nuclear’s role in future energy systems.
