France’s new environment and energy minister Francois de Rugy Wednesday said the national energy roadmap for the coming decade would be presented by the end of October. In his first interview following his appointment Tuesday, the new minister told France Inter he would “not deviate from the path of ecological transformation.” “We will do what has never been done before,” de Rugy said, referring to the multi-annual energy plans (PPE) but without providing details.

“I will meet everyone and listen to the constraints of reality. But I will not deviate from the path of the ecological transformation,” de Rugy said on his twitter account following the interview.

De Rugy was a member of the Green Party before joining President Emmanuel Macron’s LREM party last year. He has been acting as speaker of the National Assembly, according to S&P Global.

De Rugy replaces Nicolas Hulot, a former environmental activist and the most popular minister in the Macron administration, who abruptly resigned last week in a live radio interview blaming lack of support from the government.

Speaking to France Inter last Tuesday, Hulot said he had failed to persuade the government of the economic and technical “madness” of persisting with nuclear energy, which he said was “useless…economically and technically.” France last year delayed the aim of reducing the share of nuclear energy to 50% of national power production by 2025, which was made law in 2015.
