"This may not be the right protocol, but if I had warned them they might have talked me out of it yet again", Hulot said. "I don't want to create the illusion that my presence in government means that we're up to standard on these issues, and so I am deciding to quit the government". "I don't want to give the illusion that my presence in government means we're answering these issues properly - and so I have made a decision to leave the government".
The resignation comes a day after the government announced it was relaxing restrictions on hunting.
The French president, who will head to Denmark and Finland for a three-day trip from Tuesday hoping to shore up support for his European Union shake-up, called for redoubled efforts to reform the bloc.
Hulot is a former television presenter and green activist who enjoys a popular following with the younger generation of French voters, many of whom grew up watching his nature program on television in the 1990s. His inclusion helped to sustain a green image France had earned 18 months earlier by brokering the Paris Agreement to combat global greenhouse emissions.
Macron, who met Prime Minister Theresa May for talks on Britain's departure from the European Union during the summer holiday, said he wanted to reach a Brexit deal by the end of the year and showed no signs of breaking ranks with other European Union capitals. "He didn't win all his battles but that's the way it goes for ministers". "It is up to us to guarantee European security, and therefore European sovereignty", Macron told an audience of some 250 diplomats, lawmakers, and worldwide relations experts.
He had also sought a legal ban on the controversial weedkiller glyphosate but was overruled by the agriculture ministry, which preferred negotiating directly with farmers and industry.
"Political and administrative timeframes aren't necessarily as one hopes, coming from activism", an Elysee official said, insisting that Hulot's deep commitment to environmentalism was evidenced by the government's policy track record. "We're taking little steps, and France is doing a lot more than other countries, but are little steps enough?.The answer is no".
PARIS-France's high-profile environment minister was fed up with what he considered insufficient progress by his government on issues like climate change and clean energy.
Hulot's resignation took the government by surprise, but Macron, during a visit to Copenhagen told journalists that he respected Hulot's "freedom". "The response is no", government spokesman Griveaux said.
"I no longer believe", Hulot said.
"I think that in 15 months, this government has done more than any other on the subject in the same period".
