EU's Aviation Carbon Market Expansion: Implications for Global Climate Governance and India

The European Union plans to extend its Emissions Trading System (EU ETS) to international flights, potentially raising costs for airlines and reigniting debates on carbon market efficacy and equity for developing nations like India.

Key points

EU Emissions Trading System (EU ETS) expansion aims to include flights departing EU airspace, building on its existing cap-and-trade mechanism for intra-EU flights since 2012.

Carbon markets under EU ETS operate on 'polluter pays' principle, with airlines required to purchase allowances for CO2 emissions, facing a 28% reduction in free permits between 2023-2024.

[GS3-Environment] Aviation contributes 2.5% of global CO2 emissions (IEA 2023), with limited decarbonization options, making carbon pricing a critical policy tool for sectoral emission reductions.

CORSIA, the global alternative administered by ICAO, differs from EU ETS by focusing on carbon offsets through projects like reforestation rather than absolute emission reductions.

EU's move may disproportionately impact developing countries' airlines, echoing past criticisms of EU green policies creating trade disadvantages for Global South nations.

[GS2-International Relations] This conflicts with Paris Agreement's principle of Common But Differentiated Responsibilities (CBDR), as EU unilaterally extends jurisdiction beyond its borders.

Auction prices for EU ETS allowances reached €73.43/tonne in 2023, with projections suggesting €120/tonne needed by 2030 for meaningful decarbonization impact.

EU ETS has reduced sectoral emissions by 50% since 2005, generating €38.8 billion in 2024 auction revenue, demonstrating financial viability of compliance carbon markets.

This connects to GS3-Economy's 'External Sector' by potentially increasing India's aviation operating costs and trade imbalance with EU nations.

Way Forward: India should advocate for equitable global aviation agreements under ICAO, invest in Sustainable Aviation Fuel (SAF) research, and develop bilateral carbon market partnerships to mitigate EU ETS impacts.

Key terms

EU Emissions Trading System (EU ETS)

A cap-and-trade carbon market established in 2005 covering 45% of EU's GHG emissions. It sets a declining cap on total emissions, with regulated entities trading allowances. For UPSC, its significance lies in being the world's first major carbon market, influencing global climate policy architecture and testing extraterritorial application of environmental regulations.

CORSIA

Carbon Offsetting and Reduction Scheme for International Aviation, adopted by ICAO in 2016. Unlike EU ETS, it focuses on carbon-neutral growth through offset projects rather than absolute reductions. Relevant for UPSC as it represents developing countries' preferred approach to aviation emissions, highlighting North-South divides in climate governance.

Cap-and-Trade Principle

Market-based approach where a central authority sets emissions cap, issuing tradable permits. Entities reducing emissions can sell surplus permits. Crucial for UPSC as it underpins India's proposed carbon market under Energy Conservation Act 2022 amendment and demonstrates economic instruments in environmental policy.

Common But Differentiated Responsibilities (CBDR)

Principle in UNFCCC recognizing developed nations' greater historical responsibility in addressing climate change. For UPSC, this is fundamental to India's climate negotiation stance, justifying differentiated timelines and targets between developed and developing countries.
