The History of China's Chemical Industry and Environmental Protection

The relationship between China's chemical industry and environmental protection has undergone a fundamental shift from a pattern of "pollute first, clean up later" to a pursuit of "green development." Its historical evolution can be divided into the following key stages:

I. Early Stage (Pre-1970s): Germination of Environmental Awareness

• In the early years of the People's Republic, the chemical industry developed rapidly as a pillar of the national economy, but environmental awareness was weak. The philosophy of "development first, control later" was dominant.
• In 1971, the State Planning Commission established the "Three Wastes" Utilization Leadership Group. Pollution incidents like the Guanting Reservoir contamination in 1972 drew central government attention.
• The first National Environmental Protection Conference, convened by the State Council in 1973, formulated the Provisions on the Protection and Improvement of the Environment, introducing the "Three Simultaneities" system (pollution control facilities must be designed, constructed, and put into operation simultaneously with the main project).

II. Initial Exploration Stage (1976-1985): The Start of Legal Governance

• Environmental management primarily focused on controlling the "three wastes" (wastewater, waste gas, solid waste) and water pollution.
• The enactment of the Environmental Protection Law of the People's Republic of China (for Trial Implementation) in 1979 marked the beginning of placing environmental protection on a legal footing.
• During this period, planning methodologies and management implementation were in an exploratory phase.

III. Comprehensive Advancement Stage (1986-1995): Systematic Development

• National Five-Year Plans for Environmental Protection began to be issued as separate documents, integrating environmental targets into overall socioeconomic decision-making.
• The Second National Environmental Protection Conference in 1983 established environmental protection as a basic national policy.
• The concept of the "environmental protection industry" was first proposed in 1988, and the first national survey of the environmental protection industry was conducted in 1989.
• Planning standards and management implementation systems were gradually improved.

IV. Accelerated Development Stage (1996-2005): Technological Breakthroughs and Structural Adjustment

• A batch of advanced pollution control technologies emerged in the petrochemical sector.
• The "Three Shifts" were proposed in 1993: from end-of-pipe treatment to whole-process control; from concentration control to combined concentration and total load control; from scattered treatment to combined scattered and centralized treatment.
• The 1996 State Council Decision on Several Issues Concerning Environmental Protection mandated the closure of small-scale, heavily polluting "15 types" of enterprises, phasing out backward production capacity.
• The enactment of the Cleaner Production Promotion Law in 2002 signified a shift in pollution control models from end-of-pipe treatment to whole-process control.

V. Transition and Leapfrog Stage (2006-2015): Upgraded Concepts and Source Control

• China experienced rapid economic growth, accelerating the development of heavy and chemical industries, which increased pressure on the ecological environment.
• The petrochemical industry adopted concepts like the circular economy, green economy, and low-carbon economy. Environmental protection shifted from end-of-pipe treatment towards source control.
• The 11th Five-Year Plan (2006-2010) for the first time set binding targets for reducing major pollutant emissions and lowering energy consumption per unit of GDP.
• During the 12th Five-Year Plan period (2011-2015), emissions of major pollutants like chemical oxygen demand (COD), ammonia nitrogen, sulfur dioxide, and nitrogen oxides in the chemical industry continued to decline. Comprehensive treatment of volatile organic compounds (VOCs) achieved significant progress. In 2015, the sector's solid waste comprehensive utilization rate reached 62%, and the hazardous waste treatment and utilization rate reached 97%.

VI. New Era of Green Development (2016-Present): Ecological Civilization Construction

• Guided by the goal of building a Beautiful China, efforts have been made to coordinate ecological and environmental aspects, with greater emphasis placed on green and low-carbon development.
• Since the 18th National Congress of the CPC, the petroleum and chemical industry has achieved "one integration and two priorities": integrating "green" into its development philosophy, and prioritizing quality/efficiency improvement and environmental governance.
• The industry has cultivated 257 green factories, 622 green products, 30 green parks, and 8 green supply chains.
• Energy consumption per unit of crude oil processing (energy factor) decreased from 8 kilograms of standard oil/(ton·factor) to 7.5 kgce/(t·factor). Energy consumption per unit of ethylene production dropped from 640 kilograms of standard coal/ton to 590 kgce/ton.
• The implementation of the Hazardous Chemicals Safety Law in 2026 and the enactment of the EU's new "OSOA" chemical assessment rules continue to tighten environmental and safety requirements for the industry.

Key Transitions and Current State

1. Shift in Governance Philosophy: From point-source control → comprehensive prevention → cleaner production → whole-process control → green and low-carbon development.
2. Improvement of the Policy System: Evolving from single standards to systematic regulations, with innovative systems like the Three-Year Action Plan for Building a Green Industry Technical Standards System in the Petroleum and Chemical Industry being introduced.
3. Evolution of Technological Pathways: From dilution/emission and end-of-pipe treatment to cleaner production, circular economy, and whole-process pollution control.
4. International Integration: Actively fulfilling international conventions like the Minamata Convention on Mercury, driving technological upgrades in the industry.
5. Current Challenges: Still facing issues such as an incomplete technological innovation system, insufficient investment in R&D, and uneven levels of environmental awareness among enterprises.

China's chemical industry is transitioning from growth driven by scale and speed to growth driven by quality and efficiency. Driven by the "Dual Carbon" goals (carbon peak and carbon neutrality), it is accelerating its transformation towards high-end, green, and intelligent development. This history reflects China's conceptual evolution from pursuing economic growth to balancing development and protection, and it constitutes a significant practice in the global chemical industry's pursuit of sustainable development.
