China to Tax Volatile Organic Compounds in 8 Industries
China will begin collecting an environmental protection tax on volatile organic compounds (VOCs) across eight major industrial sectors starting January 1, 2027, in a landmark expansion of the country’s green tax system. The Ministry of Ecology and Environment, together with the Ministry of Finance and the State Taxation Administration, released the implementation measures on July 24, bringing hundreds of previously untaxed VOCs under the tax net for the first time.
Background and Policy Evolution
VOCs are organic chemicals that readily evaporate at room temperature and serve as key precursors to both fine particulate matter (PM2.5) and ground-level ozone, two of China’s most persistent air quality challenges. Currently, over 300 detectable VOC species exist, emitted from industrial processes, fuel combustion, and solvent use.
When China enacted its Environmental Protection Tax Law in 2016, monitoring and accounting capabilities were limited. Only 18 toxic or malodorous VOCs—such as benzene, toluene, and formaldehyde—were included in the tax scope. The legal foundation for expansion was laid in October 2025, when the Standing Committee of the National People’s Congress amended the law to authorize the State Council to conduct a pilot.
Pilot Details
The pilot targets eight industries that collectively account for more than 70% of total industrial VOC emissions: printing; chemical raw materials and chemical products manufacturing; petroleum, coal and other fuel processing; pharmaceutical manufacturing; iron and steel smelting; general equipment manufacturing; specialized equipment manufacturing; and automobile manufacturing.
The tax rate is set at 8 to 12 yuan per pollution equivalent, with provincial governments empowered to set specific rates within that band based on local environmental capacity and economic conditions. Both organized emissions from stacks and pipes and unorganized emissions from open liquid surfaces and leaking seals are included in the tax base.
According to Xinhua News Agency, the policy follows the principle of “more emissions, more tax; less emissions, less tax; no emissions, no tax.” Enterprises rated A-grade under China’s atmospheric environmental performance classification receive a 50% reduction in their tax liability, while B-grade enterprises receive a 25% reduction.
Expert Perspectives
“China’s air pollution control has entered a deep-water zone, and coordinated control of PM2.5 and ozone has become key,” said Fan Yixia, a researcher at the Chinese Academy of Fiscal Sciences. “VOCs are not only important precursors for PM2.5 formation but also key precursors for ozone generation.”
Li Junhua, a professor at Tsinghua University and director of the National Engineering Research Center for Coordinated Control of Air Pollutants and Greenhouse Gases, described the mechanism as a “positive incentive + reverse pressure” approach that would guide enterprises to implement source substitution, improve production processes, and strengthen collection and treatment, promoting deep, full-chain VOC management.
Lei Yu, director of the Institute of Atmospheric Environment Planning at the Chinese Academy of Environmental Planning, emphasized that the tax would “form comprehensive constraints on enterprise pollution emissions, prompting enterprises to bear the consequences of pollution through higher tax payments, forcing them to intensify full-chain deep treatment and accelerate green transformation and upgrading.”
Calculation and Compliance
Because VOCs are emitted from numerous source items and process stages, the implementation measures assign different calculation methods for different emission source types. For equipment sealing points, monitoring and emission factor methods apply; for raw material usage, material balance calculations are used; for other sources, emission factor methods apply.
The rollout follows a two-step approach: the pilot in these eight industries first, with evaluation and potential expansion to all industrial sectors thereafter. The State Council is required to report to the NPC on pilot results within five years of implementation and propose law amendment recommendations.
Broader Implications
The pilot represents a significant deepening of China’s green tax system, using fiscal instruments to internalize environmental externalities. By targeting sectors responsible for over 70% of industrial VOC emissions, the policy is expected to drive investment in cleaner production technologies, VOC capture systems, and process optimization.
As Xu Wen, another researcher at the Chinese Academy of Fiscal Sciences, noted, the pilot is “an important part of deepening fiscal and tax system reform and improving the green tax system.” It will promote full-chain, full-link, and full-process deep treatment of VOCs and facilitate emission reduction.
What’s Next
The three ministries will closely monitor the pilot’s progress, refine supporting regulations, and expand tax collection systems. Provincial governments will set specific tax rates within the national band, potentially creating regional variation in enforcement and burden. The State Council has until 2032 to evaluate the results and recommend further legislative changes.
For China’s industrial sector, the message is clear: the era of untaxed VOC emissions is coming to an end, and green production is becoming a financial imperative rather than merely an environmental one.
