🔥 Ladies Sizing ONLY: Small, medium, large

🌱 Eco-Friendly Materials: This shirt is organic cotton and recycled fibers—because we're not paying for something that isn’t doing double duty.

😌 Comfort AF: We're not here to be uncomfortable, okay? If this shirt isn’t the softest thing you’ve ever worn, We will be asking to speak to the manager.

🌬 They suck: Each shirt pulls 10 pounds of CO2 out of the air. Yes, you read that right. We're saving the planet and looking fabulous. Where’s my medal?

CO2 Removed by the good folks at these climate-tech companies:

My shirt removes CO2? Huh?

Each shirt removes 10 pounds of CO2. How? Science.

We take a portion of the proceeds from every shirt and use it to buy durable carbon credits from climate technology companies trying to scale Carbon Dioxide Removal (CDR).

Haven't heard of CDR? It's basically Earth’s cleanup crew for all that excess CO2 we've pumped into the sky like it’s free real estate.

But who does the actual removal of CO₂?

So, here’s the deal: a ton of new tech companies are trying to solve the CO2 problem, and no, it's not just one magical company with a giant vacuum cleaner. You've got Climeworks pulling air like it's a Dyson on steroids, Charm Industrial injecting carbon back underground like it's Botox for the Earth, and a bunch more.

At Climate Karen, we don’t play favorites—we buy carbon removal credits from all these heroes because we want to spread the love (and our money) around. Plus, helping all these techs scale means more CO2 gets yanked out faster, and that’s what we need.
