A dozen draft proposals, which still need to be approved by the bloc's 27 member states and the EU parliament, were announced on Wednesday.
They include plans to tax jet fuel and effectively ban the sale of petrol and diesel powered cars within 20 years.
The proposals, however, are likely to face months of negotiations.
The plans triggered serious infighting at the European Commission, the bloc's administrative arm, as the final tweaks were being made, sources told the AFP news agency.
