The Front National leader used her first conference of the presidential race to say humans likely contribute towards climate change and a debate is “required”.
It is thought that the leader is hoping to broaden her appeal and widen the issues she wants to tackle.
During the debate, Marine Le Pen said: ”Climate change is not a religion, it is useful for there to be a debate about what is harming the climate.
“I am not a climate expert, I think that human activity does contribute to a proportion, which I can’t measure, to this phenomenon.”
However, it marks a change in stance for Ms Le Pen who in 2012 said: “I am no sure that human activity is the principal origin of this phenomenon.”
It also puts her an odds with new US President Donald Trump on the issue who famously said climate change is very “low on the list” of priorities.
He said: “So I am not a believer, and I will – unless somebody can prove something to me – I believe there’s weather. I believe there’s change, and I believe it goes up, and it goes down, and it goes up again.”
Ms Le Pen has normally concentrated her campaign issues on immigrations, globalisation and her bid to leave the euro.
Although Ms Le Pen is expected to win the first round of the election in April, she is expected to lose in May.
The Paris Climate Agreement, which took 20 years, is in danger because of Mr Trump’s stance on the issue.
Last September former French president Nicolas Sarkozy said that humans did not have a big role in global warming.
During Ms Le Pen’s conference, she also talked about her love for France, its landscapes, is language and accents.
