Rio Explores Gujarat Emissions Trading Model for Industrial Pollution
Brazil's Rio de Janeiro is evaluating India's Gujarat emissions trading scheme, following a June 2026 partnership announcement, to curb industrial particulate matter.
Rio de Janeiro Weighs Emissions Trading System
Rio de Janeiro is currently assessing India's Gujarat emissions trading scheme (ETS) as a potential blueprint for controlling industrial pollution. The Brazilian city announced a partnership with Emissions Market Accelerator (EMA) in June 2026.
A memorandum of understanding between EMA and Rio is now undergoing legal review, according to Kaushik Deb, executive director of EPIC India.
Osmar Lima, Rio's secretary for economic development, stated that several variables are under assessment until June next year, including regulated pollutants, covered facilities, the emissions cap, initial permit numbers, governance, trading platform, and monitoring mechanisms.
Gujarat Scheme Shows Pollution Reduction
The Gujarat ETS, a cap-and-trade system focused on particulate matter, has demonstrated significant results. Textile factory Swastik Poly Prints, which joined the Surat ETS in 2019, has since reduced its particulate matter emissions by at least 30%, its owner Binay Agrawal claimed.
The Emissions Market Accelerator (EMA) observed that participating factories in Surat emitted 20-30% less particulate pollution than those operating under conventional regulations.
A pilot involving 342 industrial units showed participating plants cut particulate matter emissions by approximately 24% compared to a control group, with non-compliance rates falling to about 1% among participants.
Market-Based Approach to Industrial Emissions
Surat's scheme marked the world's first emissions trading system specifically targeting particulate matter. It functions as a compliance market, where regulators define participating industries, covered pollutants, and set the emissions cap.
Dheeraj Alshetty, deputy director of EPIC India, noted that Gujarat's initial cap of 280 tonnes of particulate emission was gradually reduced to 170 tonnes over two years. Companies like Swastik Poly Prints found financial benefits from selling surplus permits and achieved improved fuel efficiency, which further reduced operational costs and fuel consumption.
The successful implementation and potential global replication of India's Gujarat emissions trading model highlights a growing interest in market-driven environmental regulations. If adopted, Rio's market would be South America's first.
Kaushik Deb of EPIC India pointed out that while aspects like setting emissions caps and measuring industrial emissions are transferable, differences in local regulations, laws, and institutional capacity could complicate the model's adoption elsewhere.
Asian industrial hubs facing similar pollution challenges may find the Gujarat model an increasingly relevant case study for cost-effective emission reductions, potentially influencing future policy discussions beyond India.
