Remove them through carbon removal projects

The Intergovernmental Panel on Climate Change concluded in 2018 that billions of tonnes of CO₂ a year may need to be captured and buried. BACKSPACE only uses high impact, certified carbon removal technologies that literally remove CO₂ emissions from the air, backed by people like Stripe, Shopify, Microsoft and more. We do not use cheap (and inneffective) carbon credits or offsets.

Difference between carbon removal and offsets.

Currently, your CO₂ is being removed through Climeworks, who use renewable geothermal energy and waste heat to capture CO₂ directly from the air, concentrate it, and permanently sequester it underground in basaltic rock formations.

And provide insights to help reduce your emissions
