European Union nations, voicing concern over a UN report on global warming, agreed on Tuesday to seek a 35 percent cut in car emissions by 2030, as Germany warned that overly challenging targets risked harming industry and jobs.

Torn between reducing pollution and preserving industry competitiveness, EU environment ministers meeting in Luxembourg talked for more than 13 hours until nearly midnight to reach a compromise over the 2030 carbon dioxide limits to impose on Europe's powerful carmakers.

The final rules will now be hashed out in talks beginning on Wednesday with the EU's two other lawmaking bodies: the European Parliament, which is seeking a more ambitious climate target, and the European Commission, which proposed a lower one.

Climate ambition

Curbs on the transport sector, the only industry in which emissions are still rising, aim to help the bloc meet its goal of reducing greenhouse gases by at least 40 percent below 1990 levels by 2030.

Extreme temperatures across the northern hemisphere this summer have fueled concerns climate change is gathering pace, leading some countries to call for emissions to be cut at a faster rate than planned.

But a call by the EU's climate commissioner and 15 EU nations for the bloc to increase its pledge to cut emissions by 45 percent under the Paris accord has met with resistance.

Ahead of UN climate talks in Poland in December, the bloc's 28 environment ministers renewed their commitment to leading the fight to limit global warming.

They said the EU was ready to "communicate or update" its Nationally Determined Contribution, the efforts by each country to reduce emissions, by 2020.

Raising it would require the approval of all 28 nations.

That may be too hard to achieve before the UN talks, European Commission Vice-President Maros Sefcovic said, but the bloc is likely to exceed its Paris pledge following a reform of its Emission Trading System (ETS) and new targets on renewable energy and energy efficiency.

"We do not need new legislation on this one because everything is already done. We are just going to get better results than expected," Sefcovic told Reuters on Monday.
