Patagonia, the outdoor gear company, is passing along the $10 million it saved from tax cuts to non-profit environmental groups.

The Ventura, California-based company's CEO Rose Marcario said on Wednesday that the donation is in addition to the 1 per cent of sales it gives to environmental groups every year.

Corporations received a windfall from the GOP's sweeping overhaul of the U.S. tax code last year, which slashed corporate rates to 21 per cent, from 35 per cent.

Marcario called the tax cut 'irresponsible' in a statement, adding: 'Taxes protect the most vulnerable in our society, our public lands and other life-giving resources. In spite of this, the Trump administration initiated a corporate tax cut, threatening these services at the expense of our planet.'

'Far too many have suffered the consequences of global warming in recent months, and the political response has so far been woefully inadequate—and the denial is just evil,' Marcario wrote.

The donation is being made on the heels of the recent National Climate Assessment, which Patagonia cited in its announcement.

'Our government continues to ignore the seriousness and causes of the climate crisis. It is pure evil,' said Yvon Chouinard, Patagonia's founder.

'We need to double down on renewable energy solutions. We need an agriculture system that supports small family farms and ranches, not one that rewards chemical companies intent on destroying our planet and poisoning our food. And we need to protect our public lands and waters because they are all we have left.'

The report warned that natural disasters are worsening in the U.S. because of global warming.

It said violent weather and floods have led to costs of nearly $400 billion since 2015 and the potential for annual losses hundreds of billions of dollars.

Though economists agree with the general financial conclusions related to climate change, President Donald Trump has rejected the report's assessment regarding the potential economic impact.

Patagonia has joined a flurry of lawsuits challenging Trump's decision to chop up two large national monuments in Utah.

It also endorsed Democratic Sens.-elect Jon Tester of Montana and Jacky Rosen of Nevada, both who won against GOP incumbents.

The company described them as champions of public lands and the outdoor industry.
