At the start of the Copenhagen Climate Conference ECF president Manfred Neun sent a letter to all the members of European Parliament's delegation attending the conference. In this letter the ECF stated that urban traffic is responsible for 40% of all CO2 emissions.
“Transport is part of the problem. However, cycling is part of the solution. A tripling of cycling (*) in Europe at the expense of individual motorized trips, would save 49.1 million tons of CO2 or 5% of CO2 transport emissions.” (*)
