Find standards and methods for climate accounting, crediting, disclosure and responsible supply chains.
The largest voluntary greenhouse-gas crediting programme and registry, whose Verified Carbon Standard methodologies cover forest conservation, agriculture, wetland restoration and more.
Well corroborated
A high-integrity crediting standard for carbon and SDG impact, widely used for cookstove, energy and nature projects.
Well corroborated
A carbon crediting programme operating in compliance and voluntary markets, with methodologies spanning forestry, agriculture and industrial sources.
Well corroborated
The crediting standard for jurisdictional, national-scale REDD+ emission reductions, central to forest-country carbon finance.
Well corroborated
The UN carbon crediting mechanism under Article 6.4 of the Paris Agreement, supervised by a 12-member Supervisory Body, with a share of proceeds going to adaptation. Activities moving over from the Clean Development Mechanism now file through its information system, and an interim registry holds Article 6.4 emission reductions (A6.4ERs) while the full registry is built, making it the emerging compliance-grade counterpart to the voluntary standards.
Well corroborated
A North-America-focused offset registry and standards body with protocols across forestry, agriculture and industrial gases.
Corroborated
The integrity threshold for the voluntary carbon market: the Core Carbon Principles that assess whether credits meet a high-quality bar.
Well corroborated
A Claims Code setting the benchmark for how companies can credibly use carbon credits in their climate strategies.
Well corroborated
A certification body and public registry for carbon removal, capture and storage, now also certifying materials, industrial emissions and energy, with each certificate tracked from issuance to retirement.
Corroborated
A certification system for community-led climate and nature projects, with its PV Climate and PV Nature standards and a PV Climate registry.
Well corroborated
A free tool from EDF, Oeko-Institut and WWF-US that scores types of carbon credits against seven quality objectives.
Well corroborated
Four principles for credible net-zero-aligned offsetting, revised in 2024: cut emissions and use credits of real integrity, move to carbon removals for residual emissions, shift to removals with durable storage, and support innovative, integrated approaches to net zero.
Corroborated
The corporate carbon-accounting standard (Scopes 1, 2 and 3), used by 97 percent of S&P 500 companies disclosing to CDP in 2023.
Well corroborated
The body that validates corporate and financial-institution emission-reduction targets against a 1.5°C pathway.
Well corroborated
The global environmental disclosure system through which thousands of companies and cities report climate, water and forest data.
Well corroborated
The global baseline for sustainability and climate-related financial disclosure (IFRS S1 and S2), building on the TCFD recommendations.
Well corroborated
International standards for quantifying and reporting greenhouse-gas emissions and removals (ISO 14064, whose organisation-level Part 1 of 2018 is now under revision) and for carbon neutrality claims (ISO 14068).
Corroborated
Government-backed due diligence recommendations for every company in mineral supply chains from conflict-affected and high-risk areas, adopted in 2011 and written into regulations in Europe, Central Africa, the Middle East and the Americas.
Well corroborated
The global standard for transparency in oil, gas and mineral revenues, implemented across resource-rich developing countries.
Well corroborated
A multi-stakeholder standard and independent third-party audit system for environmentally and socially responsible mine sites.
Corroborated
The EU’s price on the embedded carbon of imported cement, iron and steel, aluminium, fertilisers, electricity and hydrogen, in its definitive phase since 1 January 2026 and reshaping trade for carbon-intensive exporters.
Well corroborated
EU rules making batteries sustainable across their life cycle, from the sourcing of materials to collection and recycling, with targets for recovering critical and strategic raw materials.
Well corroborated
The disclosure framework helping organisations report and act on nature-related dependencies, impacts, risks and opportunities.
