Significant reductions in CO2 emissions at major airports in Paris due in large part to geothermal energy.
In a release on its targets for CO2 emissions reductions, Group ADP, which operates the three airports in Paris, Paris-Charles de Gaulle, Paris-Orly and Paris-Le Bourget reported that they have reduced CO2 emissions by up to 63% between 2009 and 2016.
Through Paris Aéroport, the company handles more than 97 million passengers and 2.2 million metric tonnes of freight and mail at Paris-Charles de Gaulle and Paris-Orly, and more than 42 million passengers in airports abroad through its subsidiary Aéroports de Paris Management.
At Paris-Orly two wells were drilled to a depth of 1,800 meters to meet the heat requirements. The water comes up at 74 degrees Celsius. The overall district heating system is about 35 km (22 miles) long and travels through 108 sub-stations.
