The European Commission has approved an investment package of €222 million (£195m) for low carbon projects.
A total of 139 new projects in 20 Member States will share funding for environment and climate action.
Projects include testing an Italian prototype that could cost-effectively convert petrol cars into hybrid vehicles, creating bio-based products from wastewater sludge in the Netherlands and climate change adaption and mitigation.
Commissioner for Climate Action and Energy, Miguel Arias Cañete said: “The historic Paris Agreement on climate change has added wind to the sails of already accelerating climate-smart investments.
“With these projects, we use limited public finance in a catalytic way: we unlock private finance to protect the environment, fight climate change and provide cleaner energy to our citizens. These kinds of investments are of critical importance if we are to move from aspirations to action.”
