India has declined to accept a European Union proposal to levy higher taxes on its carbon-producing industries, which the 27-nation bloc said it was willing to offset when those products enter its borders, a top official told Reuters.

The latest suggestion was made by an EU delegation led by Gerassimos Thomas, director general for taxation and customs union within the European Commission, who defended the proposed carbon border adjustment mechanism (CBAM) in its meetings with Indian officials.

Ajay Seth, India's economic affairs secretary, told Reuters in an interview: "Their suggestion is not practical. Their team had come and met us ... the solution they are offering doesn't work for a developing economy like India."

New Delhi has conveyed its stance to the EU delegation, labelling the proposed CBAM as unfair and detrimental to domestic market costs, Seth said.

The EU last year approved the world's first plan to impose tariffs on imports of high-carbon goods, including steel, aluminium and cement, aiming to reach net-zero greenhouse emissions by 2050.

Negotiations between the EU and India continue at a "technical level," an EU statement said after the delegation's visit earlier this month.

EU officials are trying to win over countries like China, South Africa and India that have opposed the CBAM.

The European Commission delegation had told India that the carbon tax's primary intent was not to raise revenue but to ensure the supply of greener goods to the EU market.

The EU delegation suggested India could implement its own carbon tax to fund advancements in supply chains and cut carbon emissions, while maintaining its share of the EU market.

HIGHER COSTS

Seth said the greening of the steel industry would entail higher costs for the economy, and "with income levels which are one-twentieth of the income levels in Europe, can we afford a higher price? No, we can't."

Assuming there is no domestic Indian plan to tax high-carbon production - and incentivise a move to lower-carbon methods - the EU plans to collect the carbon tax on each consignment of steel and aluminium from Jan. 1, 2026, potentially imposing tariffs of between 20% and 35%, according to industry estimates.

Analysts warn that the deadlock over carbon emissions could strain bilateral trade and affect discussions on a free trade agreement (FTA).

"As India is negotiating an FTA with the EU, it should be ready for the scenario that Indian products will attract a high 20%-35% CBAM tax in the EU and their products will enter India duty free," said Ajay Srivastava, founder of Global Trade Research Initiative (GTRI), a New Delhi-based think tank.

The EU is India's second-biggest export destination with nearly $100 billion of exports in total in 2023.

Seth said India wants that EU to adhere to the carbon emission rules agreed in the 2015 Paris Agreement, which allowed developing nations like India more flexible emission-cutting targets compared with developed countries.

India, with a carbon intensity of 632 grams per KWh in 2022, according to think tank Ember, is expanding its renewable capacity and has reduced its carbon intensity by 3.5% since 2018. It aims to achieve net zero by 2070.

"We have now about 170 or 180 gigawatt of renewable energy, but that is not available during night time," Seth said, noting the challenges of producing greener exports solely for the EU market.
