Standing at the critical juncture of 2026, global climate governance is undergoing a profound transformation from macro-visions to micro-practices: the governance model is accelerating its shift from traditional single-policy regulation to a market-oriented collaborative system involving multiple stakeholders. In this process, carbon credits, as a core market-based allocation tool, have enabled the quantification and trading of greenhouse gas emission reductions through rigorous verification methodologies. This successfully bridges the government’s emission reduction goals, corporate cost-reduction demands, and the public’s low-carbon choices. This article will interpret the core essence of carbon credits, the current global market status, mechanism trends for 2026, and cutting-edge industry dynamics.
I. A Simple Explanation: What are Carbon Credits?
Carbon credits are greenhouse gas emission reduction certificates verified by authoritative institutions, where one unit corresponds to the reduction of one metric ton of carbon dioxide equivalent (tCO2e).
To put it simply: if a factory originally emitted 1,000 tons of carbon per year but later upgraded to energy-saving equipment and now only emits 800 tons, the 200 tons reduced can be verified by a professional third-party agency to obtain 200 carbon credits. Whether it is developing wind power, solar power, planting trees for carbon sequestration, or recovering methane, any activity that achieves “additional emission reductions” can earn this “green certificate.”
It is important to distinguish between two often-confused terms: Carbon Credits ≠ Carbon Allowances. Carbon allowances are mandatory emission caps set by governments for high-emitting enterprises, where exceeding the limit results in penalties. Carbon credits are the verified results of voluntary emission reduction actions, which can be used for compliance offsetting or carbon neutrality commitments, and can also be traded for value, creating a “reduction equals revenue” mechanism. China’s mainstream carbon credit is the China Certified Emission Reduction (CCER), which serves as a core support for corporate low-carbon transformation.
II. Global Status: Which Economies Have Carbon Credit Mechanisms?
Today, carbon credit mechanisms cover major global economies, including China, the 27 EU member states, the UK, the US, Canada, New Zealand, South Korea, Japan, India, Brazil, Mexico, Switzerland, Norway, Chile, Colombia, and Indonesia. These are divided into two major market systems: “Mandatory Compliance” and “Voluntary Emission Reduction.” Like two parallel tracks, they cater to different participants with varying rules and purposes, and are the core focus of major global industry forums:
1. Mandatory Compliance Market (Government-led, Rigid Demand)
This type of market primarily targets high-emission industries such as steel, power, and chemicals. Carbon credits act as a “compliance reserve” for enterprises and serve as the “ballast stone” of the carbon market. The most representative is the EU ETS; as the world’s largest and most mature carbon market, it has begun to include agriculture in its scope and has released a unified agricultural carbon certification methodology. China’s national carbon market, centered on the thermal power industry, is gradually expanding its coverage following the restart of CCER in 2025. Additionally, carbon markets in California (USA), Australia, and Brazil have also integrated carbon credits into compliance rules, allowing companies to offset excess emissions by purchasing credits. Regarding rule alignment and cross-border mutual recognition for these mandatory markets, a seminar titled “Establishing Cross-Border Transaction Supervision Systems to Promote the International Development of Voluntary Carbon Markets” was held in Beijing earlier this year. Hosted by the Chinese Society for Environmental Sciences and organized by the Beijing Green Exchange, it specifically outlined the paths for connecting compliance and voluntary markets, providing a practical reference for global market linkage.
2. Voluntary Emission Reduction Market (Market-driven, Flexible Participation)
CCER is the core product and officially recognized carbon credit of China’s voluntary emission reduction market. CCER stands for China Certified Emission Reduction, generated by domestic projects such as renewable energy, forestry carbon sinks, methane utilization, and energy-saving/carbon reduction. Once registered and verified by national authorities, they can be used for compliance offsetting in the national carbon market, corporate carbon neutrality, and carbon-neutral events. It is the key vehicle connecting the domestic mandatory carbon market with voluntary reduction actions.
Driven by CCER, domestic voluntary reduction scenarios continue to expand. Carbon-inclusive (Tan Puhui) mechanisms have been implemented in Beijing, Shanghai, and Guangdong, converting individual green behaviors and small-business energy-saving efforts into quantifiable, tradable reductions. These complement the CCER system to build a highly credible Chinese voluntary reduction market with wide coverage, clear rules, and traceability, providing standardized and market-based support for corporate transformation and societal participation in carbon neutrality.
Regarding the collaborative development of voluntary carbon markets in Asia, the 2nd Global Carbon Credit Market Development Forum was held in Macau at the end of March. Nearly 300 industry representatives gathered to discuss Asian carbon market practices and China-Portugal carbon cooperation. The “Macau Low Carbon Life” digital platform was also launched to further open up regional voluntary reduction trading links.
III. 2026 Innovations: What New Breakthroughs are Emerging in Carbon Credit Mechanisms?
Entering 2026, the global carbon credit market is shifting from being “narrative-driven” to “institution-driven.” Both international rules and domestic markets are seeing key changes, highlighted by four core points which will be further implemented through high-end industry summits:
1. PACM Replaces CDM: The Paris Agreement Crediting Mechanism (PACM) is a UN-backed global system designed to enhance the quality and credibility of the carbon credit market. Established under Article 6.4 of the Paris Agreement, it helps countries achieve climate goals through international cooperation and the trading of emission reduction units (A6.4ERs). Compared to private carbon markets, PACM features stricter supervision and higher public trust. PACM was formally established at COP28 in 2024, replacing the former Clean Development Mechanism (CDM). Addressing controversies regarding CDM’s credit quality and “additionality,” PACM established more rigorous standards to ensure reductions are real, measurable, and verifiable, requiring project pre-registration to improve market integrity. The first approved case was the 2025 Myanmar Stove Project, which provides efficient stoves to reduce traditional fuel use and related emissions. Furthermore, PACM utilizes a “corresponding adjustment” mechanism, requiring selling countries to deduct transferred reductions from their national accounts to avoid double counting. Supported by a unified UN registry, every credit is assigned a unique ID for full tracking and must be permanently canceled after use to prevent reuse, institutionally eliminating the issue of the same reduction being claimed multiple times.
2. Agricultural Carbon Asset Methodologies: Following the approval of the first batch of permanent removal methodologies in early 2026, the EU’s four unified certification methodologies for Carbon Farming—covering carbon sequestration in mineral soils, peatland rewetting, agroforestry, and afforestation—have entered the final adoption stage, with official signing expected in the summer. This move ends the previous chaos of private standards and provides official backing for farm-based carbon credits. With these methodologies established, the liquidity and transparency of agricultural carbon assets have significantly increased, marking the transition of agriculture from a mere emission source to a core carbon sink asset for combating climate change.
3. Continuous Expansion and Improvement of the Domestic Market:
- The CCER market is flourishing, having made the leap from “exploration” to “reshaping.” Starting in 2012 and opening for trading in 2015, it entered a suspension period in 2017 due to institutional imperfections. After six years of refinement, the Ministry of Ecology and Environment released new regulations in 2023, signaling a full restart; in early 2024, the national unified trading market was officially inaugurated in Beijing. As methodologies expanded from the initial four categories (including forestry and wind power) to 18 by 2026, the scope now covers diverse industries such as building energy efficiency, transportation, and methane recovery. CCER is effectively stimulating societal emission reduction vitality through institutionalized and standardized means, becoming a core engine for the “Dual Carbon” goals and building a regulated, highly liquid voluntary reduction system.
- Legalization of Carbon-Inclusive Systems: Meanwhile, as of April 2026, the Carbon Generalized System of Preferences (Carbon GSP) in Beijing, Shanghai, and Guangdong has transitioned from “pilot” to “legalized.” Beijing’s “Management Measures” are officially in effect, with individual carbon accounts covering over 5.6 million people. Shanghai has integrated carbon-inclusive reductions into its mandatory compliance system through deep market reforms, achieving a commercial consumption loop. Guangdong, relying on the PHCER mechanism, took the lead in promoting carbon-neutral models for large-scale events. All three regions have clarified that carbon-inclusive reductions can be used for compliance offsetting. For energy technology and carbon management professionals, monitoring the methodological differences and offset ratios across regions will be key to helping enterprises reduce costs and increase efficiency.
- First Cross-Border Carbon Sink Development: In March 2026, Jinwan, Zhuhai, achieved the nation’s first cross-border mangrove carbon sink development cooperation. Jointly developed by Zhuhai and Macau, the project aims to open a channel for converting ecological resources into international carbon credit assets.
