UN Endorses First Article 6.4 Carbon Credit Methodology

Published by Todd Bush on November 4, 2025

The United Nations (UN) has recently approved the first methodology under Article 6.4 of the Paris Agreement, representing an advancement in the realm of global carbon markets.

This initiative marks the beginning of a new phase in international carbon trading, allowing countries and companies to offset emissions under a unified global standard, reported Carbon Credits.

Key Features of Article 6.4

Global Market Creation: Article 6.4, also known as the Paris Agreement Crediting Mechanism (PACM), establishes a platform where countries can trade verified emission reductions. This mechanism aims to ensure that carbon credits are derived from real and measurable emission cuts, enhancing the credibility of carbon trading.

Replacement of the CDM: The new methodology replaces the Clean Development Mechanism (CDM) from the Kyoto Protocol, which registered over 7,800 projects from 2006 to 2020. This transition aims to improve the quality and transparency of carbon credits in the marketplace.

Support for Renewable Energy: The first approved method specifically supports renewable energy projects, focusing on small wind and solar developments in developing countries. These projects are pivotal in reducing greenhouse gas emissions and expanding access to clean energy.

Financial Implications

Climate Finance Goals: At COP29 in Baku, world governments committed to increasing climate finance for developing countries to at least $1.3 trillion annually by 2035. This funding will come from both public and private sources, with developed nations pledging to mobilize $300 billion each year.

Impact on Emissions: The World Bank estimates that cooperation under NDCs could potentially reduce emissions by up to 5 billion tonnes annually by 2030, providing a clear pathway for countries to meet their climate targets.

Market Growth Potential: Experts predict that global demand for carbon credits could reach 2 billion tonnes by 2030 and surge to as much as 13 billion tonnes by 2050, signaling robust growth in carbon trading markets.

Integrity and Transparency

Article 6.4 aims to address previous criticisms of carbon markets, particularly concerning weak integrity and unclear reporting standards. Key measures include:

Independent Audits: All projects must pass rigorous checks by independent auditors before earning credits, ensuring that only verified emission cuts are recognized.

Digital Tracking: Each carbon credit will come with a digital record, allowing buyers to trace its origin and impact, thereby enhancing accountability and transparency.

Strict Monitoring Framework: The Article 6.4 Supervisory Body will set clear baselines for emissions, measure reductions over time, and monitor performance using standardized tools.

Business and Market Response

The approval of the first methodology is expected to attract significant interest from the energy and finance sectors:

Market Value Growth: The voluntary carbon market was valued at about $2 billion in 2023 and is projected to grow to over $100 billion by 2030 as Article 6.4 trading gains momentum.

Pressure on Companies: The new system will encourage companies to purchase only verified and transparent credits, reducing the risk of "greenwashing" and enhancing corporate social responsibility.

Regional Exchanges Preparation: Carbon exchanges in Asia, Europe, and Latin America are preparing to include Article 6.4 credits in their offerings, which will help stabilize global carbon prices.

Social and Environmental Impact

The new UN system aligns with Environmental, Social, and Governance (ESG) goals and promotes sustainable development:

Job Creation: Renewable energy projects, such as solar and wind farms in Africa and Asia, are expected to create millions of jobs while improving air quality and energy access.

Alignment with SDGs: The initiatives support the UN Sustainable Development Goals (SDGs) for clean energy and climate action, emphasizing the interconnectedness of environmental and social benefits.

Future Outlook

While the approval of the methodology is a significant milestone, challenges remain before the system can reach its full potential:

Additional Methodologies: The Supervisory Body will need to approve more methodologies for complex sectors like forestry, agriculture, and industry, ensuring accurate representation of emission reductions.

Negotiations and Concerns: Ongoing negotiations between countries will address concerns about potential delays in domestic emission cuts due to reliance on carbon trading. However, proponents argue that this system will open new funding avenues for clean energy and climate adaptation projects.

Funding Needs: Developing countries are estimated to require about $4.3 trillion annually by 2030 to meet their climate and energy goals, highlighting the critical role that Article 6.4 could play in bridging this funding gap.

As the Supervisory Body prepares for its next meeting before COP30 in Belém, Brazil, the focus will be on expanding the system and ensuring it delivers real benefits for people and the planet.
