Rivian released a short film today in which the company’s CEO RJ Scaringe issues a call to action on climate change, arguing the time is now to replace fossil fuels with renewable energy solutions.

The scale of the challenge means we need to be making these changes now, and we need to begin working toward every increasing renewable content on our grid. We need to replace the roughly one-and-a-half billion combustion powered vehicles on our planet with electric vehicles, but also know that on the path to the end state, we’re going to have solutions that are imperfect, but we need to start.
