"We're done being in the middle of the herd on this issue-we've chose to use our size and scale to make a difference", Bezos said in a press release.
Bezos said Amazon will meet the goals of the Paris climate accord 10 years ahead of schedule. The 100,000 vehicles will come from a company called Rivian, in which Amazon has already invested $700 million.
The first vans will hit the road in 2021, with the fleet to be fully operational in 2030.
Additionally, more than 1,000 Amazon employees have said they plan to walk out on September 20 as part of the Global Climate Strike, of which Google and Microsoft employees also plan to participate. So to reach the goal, the company is also investing $100 million in a reforestation fund, which will work to plant trees to pull the carbon out of the air.
"The global strike tomorrow is totally understandable", Bezos said. She said she would like to see Amazon include the carbon footprint of the products it sells on its website, which could help drive people to shop for items that are less damaging to the environment. "Everybody in this room should be passionate about this issue".
Amazon has been under pressure from its own employees who asked the company to play a leading role in dealing with climate change.
Bezos was joined by Christiana Figueres, the former United Nations climate chief and founder of the climate activist group Global Optimism.
A proposal that the company report how it plans to deal with climate change received only 29.8% of votes at the shareholder meeting, despite signatures in support from almost 7,700 employees. Amazon Employees for Climate Justice said on Twitter earlier this month that more than 1,000 employees planned to participate. "We are excited to have others join".
Amazon's vehicles will share "key components" with Rivian's R1T pick up and R1S SUV, most significantly the battery and skateboard platform, but the vans will have a unique body, interior and software, Mast said.
This will involve investments in wind and solar energy projects and initiatives to curb carbon emissions at its facilities including the second headquarters, HQ2, just outside the USA capital.
Amazon is "done being in the middle of the herd" when it comes to climate-focused company policies, CEO Jeff Bezos said Thursday.
