Carbon Border Adjustment Mechanism (CBAM) – EU Tariff, Carbon Leakage, Impact on India

What is CBAM?
- CBAM is a EU tariff on carbon-intensive imports entering the European Union.
- It aims to prevent carbon leakage, i.e., shifting production to low-regulation countries.
- It ensures imported goods face equivalent carbon cost as EU-produced goods.
Objectives
- To assign a fair carbon price on imported goods.
- To encourage cleaner production practices in non-EU countries.
- To protect EU industries from unfair competition.
- To support EU’s climate goals and emission reduction commitments.
Key Features
- Applies to all imports into EU, including online goods and gifts.
- Designed to be WTO compatible, ensuring global trade compliance.
- Ensures carbon cost parity between domestic and imported goods.
- Carbon Certificates Mechanism
- Importers must purchase carbon certificates based on emissions.
- Certificate price linked to EU carbon market prices.
- Number of certificates depends on embedded emissions in goods.
- Importers must annually declare emissions and surrender certificates.
- If carbon price already paid abroad, deduction allowed.
- Countries with equivalent carbon pricing may avoid CBAM cost.
Implementation Timeline
- Transitional phase → 2023–2025 (only reporting obligations).
- Started from 1 October 2023.
- Full implementation from 2026, with financial obligations.
Sectoral Coverage
