Climate change

The greenhouse effect is an ancient and vital phenomenon that is accentuated by human activity. However, the increasing greenhouse gas concentration in the atmosphere is responsible for an additional greenhouse effect, which triggers global warming.
This higher concentration is largely due to fossil fuel consumption, which various national and international policies aim to reduce in order to lower carbon emissions. 


About COP23

Two years after the Paris Agreement, the COP23 in Bonn has helped the signatories develop regulations with a view to implement them at the end of 2018. However, this conference also saw a strong engagement on the part of non-state actors (local authorities, businesses, NGOs…), especially from the US, who introduced their work, and demanded that more action should be taken to combat climate change. To date, 169 countries that make up about 90% of the world’s greenhouse gas emissions have ratified the Paris Agreement. The need to act is nevertheless more urgent than ever, as recent studies have highlighted the speed at which climate change is taking place and the difficulties the various countries are experiencing in dealing with the consequences. International coalitions and initiatives should therefore be strengthened, along with projects bringing together public and private expertise. The best practices implemented in France and the work of ADEME within those international coalitions were presented during COP23. They dealt with issues such as low carbon building in tropical areas, the impact of climate change on islands and the introduction of efficient solutions.
