At the two-week long COP 25 climate conference, which kicked off in the Spanish capital on Monday, new EU Commission President Von der Leyen said she will make the EU the world's first climate-neutral continent by 2050 and prepare a law to make it irreversible.
"Only what gets measured, gets done. Therefore, next march we will propose the next ever European climate law to make the transition to climate neutrality irreversible."
Von der Leyen said she wants the bloc to cut carbon emissions by at least 50 percent by 2030, compared to 1990 levels.
It's ten percentage points higher than the current agreed goals of 40 percent by 2030.
She has even hinted at the possibility of raising the target to 55 percent, but some critics say that such an ambitious goal would damage European industry.
The European Commission is also expected to work on a carbon border tax and reform the EU's emissions trading system.
Also at the conference, UN Secretary-General Antonio Guterres said the planet is "close to a point of no return", asking for full engagements by big polluters and saying the green economy is a new opportunity, not a threat.
"Without the full engagements of the big emitters, all our efforts will be undermined. A green economy is not one to be feared, but an opportunity to be embraced and one that can advance our efforts to achieve all the sustainable development goals."
This year, the U.S., China and India, the world's biggest emitters, plan to dispatch high-level officials to the conference on behalf of their leaders.
As well as Washington's formal representatives, U.S. House of Representative Speaker Nancy Pelosi also attended the conference.
