The EU executive is expected to present a revision of the Emissions Trading System around July.

BRUSSELS — The European Commission plans to propose a reform of the carbon market reserve before revising the Emissions Trading System (ETS) as a whole this year, the bloc’s climate chief said.

The EU executive is expected to present a revision of the ETS, which obliges factories, power plants, airlines and shipping companies to pay for their planet-warming pollution, around July.

But Climate Commissioner Wopke Hoekstra said Tuesday that a reform of the Market Stability Reserve, which controls the supply of ETS permits, will come beforehand.
