Executive Vice-President for the European Green Deal Frans Timmermans has said the EU stands firmly behind the Paris Agreement and the transition to a climate neutral future.
Speaking in the European Parliament in Strasbourg this evening, he said the commission believes in a Green Deal for Europe.
He said the COP25 summit in Madrid did not deliver what it was supposed to on carbon markets and other issues.
However, he said the EU wants action and a plan for the climate and he said they could not support rules that would undermine the integrity of global climate action.
Mr Timmermans said Europe will build on a global consensus to increase climate ambitions worldwide.
The UN Climate Summit ended on Sunday with just a modest agreement on the key question of increasing the global response to curbing carbon.
The final agreement highlighted the ''urgent need'' to cut greenhouse gases in line with the goals of the landmark 2015 Paris climate change Agreement.
However, divisions over other issues including carbon markets - were delayed until COP26 in Glasgow in Scotland next year.
Officials from almost 200 countries had extended their stay in Madrid as they struggled to resolve outstanding issues under the 2015 Paris Agreement..
Mr Timmermans told the Parliament that by COP26 long term strategies need to be submitted in line with the Paris Agreement objectives.
He also said the most vulnerable must be helped in their climate efforts so they have the capacity to deal with the changes.
Mr Timmermans said Europe remains committed to boosting climate finance and support developing countries.
He said the Commission and the Parliament know that young people want a concrete climate plan.
He said the Green Deal was a start for Europe to reinvent itself and he said it was a once in a lifetime opportunity to develop a greener and a cleaner future.
Speaking in the Parliament this evening, Irish MEP Mick Wallace who is part of United European Left group, described COP25 as a letdown.
He said right wing countries like Canada, the USA and Brazil were preventing the EU from reiterating the Paris Agreement requirements in the COP conclusions.
Mr Wallace said the idea that climate diplomacy was an affect tool is a "myth".
Meanwhile, Irish MEP Billy Kelleher, who is a member of the Renew Europe Group, said he welcomed the commission's Green Deal.
He said it was important that the EU shows leadership in a global context and he criticized countries like Brazil and the US who he said do not accept the climate crisis.
He said COP25 highlights the fact that there are still a number of countries that will jeopardise the climate for economic gain.
Mr Kelleher said diplomatic efforts needed to be enhanced to encourage countries to bring forward tangible proposals to transition to a carbon neutral world.
MEP Sean Kelly, who is a member of the European People's Party, said he was pleased that COP25 was being labelled a failure.
He said this gave the commission a new opportunity to use the next 12 months to put pressure on big carbon emitters to live up to their environment commitments.
