Our Philosophy


At HC3, we believe that climate change is the most dire threat actively jeopardizing lives and well-being around the globe.

We believe science & engineering are incredibly powerful tools to help fight climate change.

We acknowledge that technology alone is not the answer; it must be accompanied by political action and long-term cultural shifts. This is why we invest at least 2% of profits into a political action group and encourage our employees to be civically active.

We fight capitalism with capitalism: sustainable products aren't more appealing because they're "green", they're more appealing because they waste less, cost less, are more effective, and keep us healthier.

We fight not for polar bears or ice caps or honey bees, but because we want to preserve our way of life. This is for us: our families, our friends, and our futures.
