17 Oct Technology and climate change: several solutions to mitigate the effects and to adapt (Executive Summary in English
National Academy of Technologies of France (NATF) 2016
The report takes stock of available or future technologies for mitigating climate change. First conclusion: climate-engineering, in the current state of knowledge, is not an alternative.
It identifies the most favourable conditions, especially in the most contributing sectors, for reducing greenhouse gas (GHG) emissions and promoting preventive adaptation measures, including a carbon emission penalty. The cost of increased energy efficiency must be less than the value of the energy saved and, as the case may be, the worth of CO2 not emitted. The same cost-benefit analysis should apply for any mitigation technology considered. Preventive adaptation measures are possible in agriculture, forestry, energy, urban environment, manufacturing, coastal protection, access to safe water, resources management, etc. Moreover, involving civil society (lifestyles and behaviours) will be important for reducing GHG emissions. And we must not forget technologies in developing countries, which are often more vulnerable to climate change than the richer developed countries.
