Cap-and-Trade India

Context: A recent study published in The Quarterly Journal of Economics confirmed that Surat’s Emissions Trading Scheme (ETS), the world’s first market for particulate emissions — reduced pollution by 20–30% and lowered compliance costs by 11%.

What is Cap-and-Trade?

Cap-and-Trade is a market-driven environmental policy where the government sets a maximum limit (cap) on the total level of pollution that can be emitted by industries.

• Under this system, companies are issued pollution permits that allow them to emit a specific number of pollutants.

• If a firm emits less than its permitted share, it can sell its unused permits to other firms struggling to meet their limits.

• This creates a financial incentive for industries to reduce pollution efficiently and invest in cleaner technologies, as doing so can turn into a profit opportunity.

How Does Cap-and-Trade Work?

• Regulatory Cap Setting: The government or regulatory authority sets a total emissions ceiling across all participating firms, based on environmental goals (e.g., air quality improvement, climate targets).

• The government or regulatory authority sets a total emissions ceiling across all participating firms, based on environmental goals (e.g., air quality improvement, climate targets).

• Permit Distribution: Pollution permits are then allocated: Free allocation to firms based on past emissions (grandfathering method). Auctioning a portion of permits, allowing the market to determine their price. Trading System Among Firms:

• Trading System Among Firms:

• Companies that can cut emissions cheaply will do so and sell their surplus permits. Companies facing higher abatement costs can buy permits to remain compliant rather than investing heavily in immediate technology upgrades.

• Companies that can cut emissions cheaply will do so and sell their surplus permits.

• Companies facing higher abatement costs can buy permits to remain compliant rather than investing heavily in immediate technology upgrades.

• Penalties for Non-Compliance:

• Firms failing to hold sufficient permits for their actual emissions face strict financial penalties. Penalties ensure that it remains cheaper to comply by reducing pollution or buying permits rather than paying fines.

Challenges to Cap-and-Trade Model:

• Monitoring gaps: Effective cap-and-trade relies on precise, real-time emissions data, which demands continuous oversight and maintenance of monitoring systems.

E.g. Surat’s success was linked to CEMS installation.

• High initial setup cost: Setting up infrastructure like Continuous Emissions Monitoring Systems (CEMS) can be financially burdensome, especially for small industries.

E.g. CEMS installation was mandatory for 317 industries.

• Market manipulation risk: Industries could collude to hoard permits, manipulate prices, and undermine the true spirit of emissions trading unless strict controls are enforced.

E.g. Weekly auctions were introduced to avoid hoarding.

• Sectoral variations: Pollution abatement costs differ across industries, creating uneven advantages where some firms may find it easier to profit from permit trading.

E.g. Cost of abatement varies greatly across sectors.

• Policy instability: Frequent and unpredictable changes in cap levels or trading rules can discourage long-term industrial investments in clean technologies.

E.g. Surat ETS cap was adjusted after pilot phase data review.

Way Ahead:

• Expand ETS to other cities: Scaling cap-and-trade to other polluted urban-industrial centers can maximize its impact and build a nationwide pollution control framework.

E.g. Delhi, Ahmedabad and others planning new pilots.

• Include more pollutants: Broaden the ETS to cover gases like sulfur dioxide (SO₂) and nitrogen oxides (NOx) to comprehensively tackle industrial pollution.

E.g. Gujarat considering sulfur dioxide cap-and-trade next.

• Invest in CEMS technology: Boosting investments in reliable, tamper-proof CEMS technology will ensure greater transparency and regulatory efficiency.

E.g. CEMS critical for Surat’s verifiable data success.

• Set dynamic emission caps: Emission caps must be adaptable to account for seasonal pollution variations and industrial production cycles for better effectiveness.

E.g. Surat’s cap revised from 280 to 170 tonnes/month.

• Enhance stakeholder engagement: Active participation of industries, local bodies, and citizens through awareness campaigns can ensure broader acceptance and success.

E.g. Surat industries collaborated with GPCB during roll-out.

Conclusion:

Surat’s Emissions Trading Scheme proves that market-based solutions can effectively balance economic growth with environmental protection. Scaling such initiatives nationwide could be vital for achieving India’s clean air targets while fostering industrial efficiency.
