The EU Parliament could the first institution in the region to become 100% carbon neutral by 2016.
It set the target just weeks ahead of the COP21 conference in Paris.
It is investing up to €250,000 (£175,000) to reduce its carbon footprint by making better use of energy, water and paper in line with its environmental policy to reduce emissions.
Its plans include the reduction of emissions from MEPs’ flights between their countries of origin and Brussels and Strasbourg.
Vice President Ulrike Lunacek, responsible for the EU Eco-Management and Audit Scheme (EMAS), said: “With this step towards 100% carbon neutrality the European Parliament will play its part in limiting the impacts of climate change.
“Some weeks ahead of COP21 in Paris this is a great signal from inside the European Institutions showing that we are willing to live up to our goals. The EU will have to seriously raise its ambition if it is to play a positive role in making COP21 a success. In this way, Parliament is setting a good example in promoting best practice.”
