"The Terminator" Arnold Schwarzenegger says US President Donald Trump is making a "big mistake" on environmental policy.

Making his annual pilgrimage to the famous ski races in Kitzbuhel, the Austrian muscleman, movie star and former governor of California was in the grandstand to watch the second leg of today's race.

Schwarzenegger, who launched the R20 climate change organization in 2011, said seven million people die every year because of global pollution, a reference to a World Health Organization report released in December.

Schwarzenegger said Trump would one day regret his June 2017 decision to pull the United States out of the Paris Agreement on climate change by 2020.
