The EU's Proposed Overhaul of Its Carbon Market: What You Need to Know

By Kate Abnett

Key Changes in the EU Emissions Trading System Proposal

BRUSSELS, July 17 (Reuters) - The European Commission proposed sweeping changes on Friday to the EU's emissions trading system, Europe's biggest climate policy, allowing industries to emit ​CO2 longer while offering more financial support to invest in clean technologies.

Here's what you need to know.

Speed of CO2 Cuts

How the ETS Works

The European Union's ETS forces power plants and heavy industries to buy a permit for every metric ton of CO2 they emit, and caps the number of permits released each year to make sure emissions gradually decrease.

Proposed Changes to Emissions Cap

The Commission proposed slowing the rate at which this cap declines, lowering the "linear reduction factor" to 3.7% in 2031 and 1.7% in 2036 from 4.3% today, effectively slowing the rate at which companies will have to cut emissions.

Market Stability Reserve Adjustments

The proposals would also halve to 12%, from 24% today, the rate at which a "market stability reserve" adds or removes permits from the ETS if supply fluctuates dramatically. 

Both changes mean more CO2 permits will remain available in future years for industries to buy, giving them leeway to emit more.

The EU will also buy international carbon offset credits to cover 2% of the emissions reductions required by ETS sectors, softening the efforts required by domestic industries.

While the changes will slow down the ETS, the Commission said they were designed to make sure the system still meets the EU's 2040 climate goal to cut net emissions by 90%. The ETS covers around 40% of EU emissions.

Free Permits

Extension and Conditions for Free Permits

The Commission proposed giving heavy industries free CO2 permits until 2038, rather than ending them ​in 2034, for sectors including steel and cement production.

The free permits are no free lunch, though. The Commission wants to attach conditions to them, granting 80% upfront to ‌companies that have plans to invest in decarbonisation in Europe. Companies would get the remaining 20% only after those investments are made.

Incentives for Efficient Firms

As a reward to firms investing in cutting CO2, the 10% most efficient industrial installations won't face these conditions.

Benchmark Adjustments and Extra Free Permits

The EU proposed giving industries more free permits overall than currently planned, by reducing the "benchmark" rate which cuts these handouts each year to 2% from 2030 from 2.5% today. 

A separate, fast-tracked proposal will also soften these benchmarks for 2026 to 2030, handing industries extra free permits worth €6 billion ($6.86 billion), the Commission said.

Funding

Allocation of ETS Revenues

The ETS has generated €260 billion in revenue since 2013. Of this, 80% went back to the national budgets of governments, which the EU estimates invested only 5% in industries.

Proposed Investment Requirements

The Commission proposed that governments will have to spend at least 50% of their future ETS revenues on domestic industries, a move likely to face resistance from finance ministries who use the proceeds to plug national budget gaps.

Booster Fund and Continued Support

The EU will also set aside 400 million carbon permits — worth around €30 billion — until 2030 as an investment "booster" fund to help industries invest in clean tech.

An existing fund which spends ETS revenues on clean energy investments in the EU's poorest member countries will also be continued past 2030, with 280 million CO2 permits earmarked for this.

Planes, Ships

Expansion to Aviation

The Commission proposed expanding the ⁠ETS to ​cover emissions from flights departing Europe for destinations up to 5,000 km (3,107 miles) ​away — a move that would capture trips to Dubai and Istanbul, but not the U.S. or China.

Currently, the ETS only applies to flights within Europe.

Expansion to Shipping and Waste

The EU also proposed adding emissions from ships as small as 400 gross tonnage to the ETS, down from 5,000 today.

Emissions from waste incineration will also be added to the ETS gradually, from 2031 to 2034. Countries can dodge this until 2035 if they meet conditions including having a national carbon tax, or being on track to meet EU recycling targets.

Next Steps

Legislative Process

EU countries and the European Parliament will propose their own amendments, and negotiate the final rules. That process can take a year.

Key Takeaways

  • Linear reduction factor for the annual emissions cap would be slowed to 3.7 % in 2031 and 1.7 % in 2036, down from 4.3 % today, weakening the speed of CO₂ cuts while still aiming for 90 % emissions reduction by 2040 (europarl.europa.eu).
  • Market Stability Reserve intake rate would halve to 12 % (from 24 %) to smooth supply fluctuations, and the EU would buy international carbon offsets to cover 2 % of required reductions (europarl.europa.eu).
  • Free CO₂ permits for heavy industry are extended to 2038 (instead of ending in 2034), with 80 % conditional on decarbonisation investment, and the 10 % most‑efficient installations exempt from conditions; benchmarks would decline at 2 % annually from 2030 (down from 2.5 %) plus a fast‑tracked €6 billion permit boost for 2026‑30 (europarl.europa.eu).
  • Member states would need to spend at least 50 % of their future ETS auction revenue on domestic industry (versus ~5 % currently), and the Commission would reserve 400 million permits (~€30 billion) for a clean‑tech investment “booster,” plus 280 million for poorer member states (europarl.europa.eu).
  • ETS scope would expand to cover flights departing for destinations up to 5,000 km (e.g., Dubai and Istanbul), but not long‑haul routes to the U.S. or China (europarl.europa.eu).

Frequently Asked Questions

What changes are proposed for the EU Emissions Trading System (ETS)?
The EU proposes slowing the cap decline on CO2 permits, increasing support for clean tech investments, and expanding ETS coverage to more industries and transport sectors.
Will heavy industries continue getting free CO2 permits?
Yes, free CO2 permits will continue until 2038 with new conditions requiring investments in decarbonisation and a reduction in the benchmark rate for permit handouts.
How will the new plan impact ETS revenue spending?
At least 50% of future ETS revenues must be spent on domestic industries, with significant funds set aside to support clean tech and investments in poorer EU states.
Which new sectors will be included in the EU ETS?
The ETS will expand to cover more flights and shipping emissions, plus waste incineration, with gradual implementation and certain exemptions for compliant countries.
What are the next steps for the EU's carbon market reforms?
EU countries and the European Parliament will debate and negotiate final ETS rules, a process expected to take about a year.
