Answer

Introduction

In face of worsening pollution and revenue pressures, a comprehensive pollution tax could price environmental externalities, raise fiscal resources, and incentivise cleaner production but requires careful design to protect equity, competitiveness and effective use of proceeds for green transitions.

Body

Proposition 

• Internalise Costs:  A pollution tax makes polluters pay, correcting market failure and discouraging harmful emissions economically.
  Eg: India’s Clean Energy Cess (2010) taxed coal to internalise environmental costs. 
• Revenue Mobilisation: Tax yields can provide stable, dedicated funds for pollution control and green investments.
• Behaviour Incentives: Price signals encourage firms and consumers to adopt cleaner technologies and reduce emissions.
  Eg: Global carbon pricing discussions and CBAM debates highlight incentive effects on industry. 
• Trade Resilience: Domestic pollution pricing may protect export competitiveness against foreign carbon border measures.
• Policy Complement: A pollution tax complements regulations, subsidies and market instruments for a comprehensive climate toolkit.

Associated Challenges 

• Equity Concerns: Pollution taxes can be regressive, burdening poor households via higher energy and transport costs.
• Competitiveness Risk: High taxes may raise production costs, harming energy-intensive industries and exports.
• Implementation Complexity: Measuring pollution footprints accurately across sectors and enforcing collection is administratively hard.
• Political Acceptability: Visible price rises provoke public opposition; political costs can block or weaken policy.
• Revenue Use Credibility: Poor earmarking or misuse of proceeds undermines trust and the policy’s environmental purpose.

How to overcome challenges

• Targeted Transfers: Use part of tax revenue for cash or subsidy offsets protecting low-income households from price shocks.
• Phased Rollout: Introduce tax gradually with predictable increases, allowing firms time to transition technologies.
• Industry Differentiation: Provide temporary relief or support for energy-intensive MSMEs, coupled with green upgrade subsidies.
• Transparent Earmarking: Create an independent green fund with audited allocations for pollution control and clean infrastructure.
  Eg: The NCEEF (National Clean Energy and Environment Fund-created with coal cess) illustrates the concept of a dedicated environmental fund. 
• Robust Measurement: Build strong monitoring systems, emissions accounting and digital reporting to ensure reliable tax bases.

Conclusion

A well-designed pollution tax phased, equitable, and transparently earmarked can curb emissions and raise green finance; success depends on credible measurement, revenue recycling to protect the poor, and policy coordination to safeguard competitiveness.
