Emission Control Catalysts Market Report 2026

The emission control catalysts market size has grown rapidly in recent years. It will grow from $29.48 billion in 2025 to $32.89 billion in 2026 at a compound annual growth rate (CAGR) of 11.6%. The growth in the historic period can be attributed to stricter environmental emission regulations, expansion of automotive production volumes, growth in industrial combustion equipment, rising adoption of diesel emission controls, improvements in catalyst coating technologies.

The emission control catalysts market size is expected to see rapid growth in the next few years. It will grow to $49.94 billion in 2030 at a compound annual growth rate (CAGR) of 11%. The growth in the forecast period can be attributed to increasing tightening of emission norms worldwide, rising adoption of low-emission industrial processes, expansion of electric and hybrid vehicle platforms, growing investments in catalyst recycling, increasing focus on cost-effective emission reduction. Major trends in the forecast period include increasing adoption of advanced catalyst formulations, rising use of precious metal optimization techniques, growing demand for industrial emission control, expansion of stationary emission applications, enhanced catalyst durability and efficiency.

Stringent regulations aimed at controlling air pollution are significantly driving the growth of the emission control catalysts market. Air pollution is primarily a result of rapid industrialization and urbanization, which contribute to increased emissions in the environment. Governments are increasingly concerned about the negative impacts of air pollution on public health and the environment, leading to the implementation of regulations designed to mitigate air pollution. This has heightened the demand for emission control catalysts in the exhaust systems of industrial machinery and vehicles. For example, in September 2023, the United Nations Environment Programme (UNEP), a US-based government entity, reported that air pollution is the greatest environmental threat to global public health, responsible for over 8 million premature deaths annually. Consequently, the stringent regulations for controlling air pollution are expected to further propel the growth of the emission control catalysts market in the future.

Major companies in the emission control catalysts market are concentrating on developing innovative solutions, such as automotive emissions control technologies, to reduce harmful pollutants like nitrogen oxides (NOx), carbon monoxide (CO), and hydrocarbons (HC). Automotive emissions control solutions encompass technologies and systems specifically designed to diminish or eliminate harmful pollutants emitted by vehicles. For example, in August 2024, Boff Catalyst India Mountain Ltd., an India-based chemical manufacturing firm, announced the inauguration of a new Research, Development, and Application (RD&A) laboratory aimed at advancing automotive emissions control solutions. This state-of-the-art facility is intended to develop novel catalyst technologies that comply with stringent emission standards, including Euro 7 and Bharat Stage VI (BS6). Equipped with advanced testing capabilities, the lab will conduct comprehensive validation procedures for various catalysts used in both gasoline and diesel engines.

In September 2024, TPG Capital, a US-based private equity firm, acquired Miratech for an undisclosed sum. This acquisition is intended to bolster TPG's emissions reduction solutions to address the growing power demands from data centers, which are increasingly influenced by AI and cloud migration. It also aligns with TPG's commitment to negative emissions technologies and its efforts to meet regulatory pressures for cleaner energy solutions. Miratech is a US-based company specializing in industrial emissions reduction technologies.
