>> World leaders and the biggest names in business arriving by boat for a climate change conference in Paris though no sign of business man turned president Donald Trump. French President Emanuel Macron organized the One Planet Summit back in the summer, just days after Trump announced he was pulling the United States out of the Paris Climate Accord.
Reuter's Richard Locke is in Paris.>> Macron had invested quite a lot of political capital in trying to get Trump and the United States to stay inside that agreement. It didn't work out. And he, Macron came out afterwards saying.>> Make our planet great again.>> Something of a twist, a play on words of Trump's own presidential campaign.
What Macron wants to show here is that the process is still very much alive. Even after Trump announced the US pullout and with it, all those dollars.>> In a pointed piece of timing, Macron used the eve of the summit to award 18 Make Our Planet Great Again grants to foreign climate scientists.
Most of the winners are currently based in the US and will now relocate to France. And they weren't the only Americans in town.>> Interestingly that while the official US delegation is a low level one, it's just sending delegation from the Embassy here in Paris, the govenor of California, the world's sixth biggest economy, is here.
So too is Arnie Schwarzenegger and Leo DiCaprio. So still plenty of money and plenty of big hitting US names behind that Paris Accord of 2015.>> Various pledges were made at the summit, including 200 institutional investors who manage $26 trillion of assets, saying they would increase pressure on the world's biggest corporate greenhouse gas emitters.
Macron will be hoping actions like that are enough to push the Paris Accord ahead, without the United States.
