The website launched by French President Emmanuel Macron Macron trolls Trump with ‘Make our Planet Great Again’ website Initiative encourages scientists and entrepreneurs to move to France to work on climate change.

PARIS — Take that, Donald.

French President Emmanuel Macron launched a website Thursday encouraging anyone concerned about climate change to emigrate to France.

Its address — www.MakeOurPlanetGreatAgain.fr — uses the same riff on Donald Trump's campaign slogan that Macron unveiled the day the U.S. president announced his decision to withdraw from the Paris climate deal.

The site invites researchers, entrepreneurs and NGO workers from around the world (although an aide chose to feature a researcher from California during a demonstration for reporters) to state their interest in climate change and their specialist field, then apply for positions and immigration documents to come to France. A team of 10 people in the administration is charged with reviewing expressions of interest and replying to them.

"This is a signal sent to the rest of the world," an adviser to Macron said, briefing reporters on condition of anonymity? "France wants to lead the fight against climate change and we want to attract people who share that aspiration."

At the unveiling, journalists questioned the site's purpose beyond offering a portal for links to French universities or the opportunity to speak to a member of Business France, a state-run business development program.

France has yet to devote new funds to positions in climate-related research. Jobs in academia tend to be less well-paid than in the United States and access to top research programs is extremely tight.

"This is a first step," said another aide, who said the presidency was studying the possibility of allocating funds for the outreach program.

The site, which cost €22,000 to build, is part of a public relations drive by Macron — who took office less than a month ago — to capitalize on Trump's decision to withdraw from the climate change deal, and underscores his presidency's exceptionally active approach to communications.

The slogan and accompanying graphics were ready to go last week when Trump made his announcement. A "Make Our Planet Great Again" tweet from Macron's account was retweeted more than 230,000 times — the most for any tweet in France, according to presidential advisers.

Coming after Macron's white-knuckled handshake with Trump and his publication of an "unofficial" photo from the G7 summit from which Trump was absent, the site launch is another gesture by the French president to distinguish himself from his U.S. counterpart.

Macron is in the midst of a parliamentary election campaign and French media have hailed his show of strength with Trump as proof of a vigorous presidency.
