1.8 - CO2 emissions and climate

Version 3


    Global warming has been accelerating since the beginning of the Industrial Revolution. Greenhouse gas (GHG) emissions have been identified as one of the causes. The transport sector’s share of greenhouse gas emissions continues to grow and likewise the global fleet of vehicles.


    To keep the temperature rise to less than 2°C by 2050 compared with 2005, the goal is to lower global emissions by 50 % by the mid century.


    The challenge is to foster the development of mobility without accelerating global warming.

    To achieve this, it is urgent to lower fuel consumption, to move to second and third generation biofuels, to develop electric vehicles while diversifying the primary energy sources. There is also the option of making greater use of more efficient modes of transport.

    Significant investments and funding will be needed to support strong policies and an effective implementation. We have the means to act and to considerably lower CO₂ emissions by 2050, in particular in the field of transport.
