The union plans to cut emissions from road transport, building heating, farming, light industry and waste management by 40 percent by 2030, compared to their level in 1990.

But not all member states will face the same targets and, with the COP27 climate talks underway in Egypt, officials and lawmakers met late Monday in Brussels to divide the task.

These targets vary depending on a member state's GDP per capita and the cost-effectiveness of the cuts it is proposing.

The lowest goal is a 10 percent reduction in the targeted sectors for Bulgaria, while Denmark, Germany, Finland and Sweden must bring their emissions down by half.

There will also be a system for trading emissions allowances between member states and countries that exceed annual targets and can save unused allowances for later years.

"The new rules for national emission cuts ensure that all member states contribute and that existing loopholes are closed," said MEP Jessica Polfjard.

"This allows us to go to COP27 with a clear signal that the EU is serious about being the global champion for a competitive and efficient climate agenda."

The economic sectors covered by the agreement represented 60 percent of the total EU greenhouse emissions, with the rest subject to the EU carbon market and other regulations.

The EU climate plan aims to slash all emissions, across all sectors, by 55 percent by 2030, compared to 1990.
