Nuclear energy for climate change, trend or real solution?

Chernobyl, 20 years after the nuclear accident.

The COP 25 context.

The 25th Conference of Parties (December 2019) was, thus, the right time for EU to show support to the United Nations. The postponement of the Nuclear shut down is a different debate in every country and it involves many actors at different levels. Together at COP25, UN and EU intend to convince the largest audience possible (from activists to other official bodies, nations, media, businesses or financials) that nuclear energy is a necessity, at least, on the short term.

Nuclear Energy could be a reliable and relevant solution to meet short term CO2 emissions objectives. However, the national nuclear shut down laws and debates are still quite fresh in many people’s mind. Therefore, UN & EU have been portraying the nuclear energy postponement as a step backward that would enable a 100% renewable energies world in the future. On Twitter, they have been over-sharing their position which has led to a massive proportion of pro-nuclear tweets although it doesn’t really reflect the offline reality.
