SURAT EMISSIONS TRADING SCHEME:
ENVIRONMENT
NEWS: World’s first market
for particulate emissions trading in Gujarat, how it worked
WHAT’S IN THE NEWS?
The Surat Emissions Trading Scheme
(ETS), the world’s first market targeting particulate matter, reduced pollution
by up to 30% while lowering abatement costs through a cap-and-trade mechanism.
Despite its success, challenges like regulatory capacity, compliance equity,
and systemic rigidity remain barriers to wider adoption.
Context: Experimental Evidence from Surat ETS
- The
world’s first particulate matter emissions trading market,
implemented in Surat, Gujarat, has shown a 20–30% reduction in
particulate pollution among participating industries.
- The
pilot has also demonstrated lower abatement costs, making it a cost-effective
alternative to traditional environmental regulation.
Emissions Trading Scheme (ETS): Overview
- ETS is
a market-based regulatory approach aimed at reducing emissions by
offering economic incentives to polluters who stay within set limits.
- It is
commonly known as a “cap-and-trade” system.
- Unlike
the traditional command-and-control model, ETS uses tradeable
permits to provide flexibility and financial motivation for cleaner
production.
How ETS Works: Key Mechanisms
- Cap
Setting: Regulators fix a total emission limit (cap) that
industries must not exceed. This is based on environmental goals,
pollution load, and industry capacity.
- Permit
Allocation: Industries are allocated or buy emission permits
(each representing a fixed quantity of allowable pollution).
- Trading:
- Industries
that reduce emissions below their limit can sell excess permits.
- Those
unable to reduce emissions immediately can buy additional
permits, ensuring compliance while transitioning to cleaner
technologies.
- A floor
price and ceiling price are used to stabilize the market and make
trading predictable.
- At
the end of a trading cycle, firms submit emission data verified through
monitoring systems.
- Non-compliance
results in penalties, often calculated per unit of excess
pollution.
- Over
time, regulators tighten the cap to drive progressive reductions
in emissions.
Surat Emissions Trading Scheme: Features and Implementation
- Launch:
Initiated in 2019, Surat’s ETS is the first global program
specifically targeting particulate matter (PM) pollution.
- Key
Collaborators: Gujarat Pollution Control Board (GPCB), J-PAL,
EPIC-India, and Yale University.
- Objective:
Transition from rigid regulatory frameworks to market-based
environmental governance in India.
Working Model of Surat ETS
- Started
with 280 tons/month of Suspended Particulate Matter (SPM).
- Based
on real-time data from Continuous Emission Monitoring Systems
(CEMS), this cap was revised to 170 tons/month.
- 1
permit = 1 kg of PM emissions.
- Permits
valid only for one compliance cycle (4–6 weeks).
- 80%
of permits were allocated for free, based on historical emissions and capacity.
- 20%
of permits were auctioned using a uniform price discovery
system.
- Buyers
and sellers bid within a fixed price range:
- Floor
Price: ₹5 per kg
- Ceiling
Price: ₹100 per kg
- A single
clearing price is determined for all participants at the start of
each cycle.
- Each
firm deposited a compliance bond called the Environmental
Damage Compensation Deposit.
- Firms
exceeding their permit quota were fined double the ceiling price
(i.e., ₹200 per kg of excess emissions).
- Fines
were deducted from the deposit to ensure prompt enforcement
without litigation.
Significance and Outcomes of Surat ETS
- Participating
industries saw a 20–30% drop in particulate emissions.
- Firms
found it more economical to either reduce emissions or trade permits,
lowering overall compliance and abatement costs.
- Represented
a scalable, flexible, and market-aligned model for pollution
control.
- Can
serve as a template for expanding emissions trading to other
Indian cities and pollution types (e.g., SO₂, NOx).
Systemic Limitations and Challenges of ETS
- Thousands
of small and medium polluting units exist, but regulatory manpower is
limited.
- Monitoring
and enforcement lag due to shortage of skilled personnel and technology
deployment.
- Uniform
Compliance Burden:
- All
industries are treated equally in terms of compliance expectations,
regardless of their technological sophistication or financial strength.
- This disadvantages
smaller enterprises, which may lack the resources to adopt cleaner
technologies immediately.
- Traditional
command-and-control systems still dominate outside the ETS framework,
offering little scope for flexibility.
- Rule-based
enforcement often involves high administrative and transaction costs,
and lacks incentives for innovation or overperformance.
Conclusion and Future Prospects
- The
Surat ETS demonstrates that market-based solutions can achieve
environmental goals more efficiently than blanket regulations.
- With proper
monitoring, technological support, and stakeholder training, ETS can
be expanded to other Indian industrial clusters.
- However,
to ensure inclusive and effective implementation, future schemes
must address regulatory capacity, equity for smaller firms, and
localized adaptability.
