This is just a rough estimation

This estimation is based on a single page visit and some assumptions Learn moreEmissions are calculated through the data transferred during a visit. Since we don't know your sitemap and traffic per page, we only measure the exact URL address you provided and assume 75% new visitors and 25% returning visitors (to account for caching on returning visitors).

BACKSPACE accurately measures every single visit your website has down to the gram of CO2.

If the internet were a country, it'd be the

7th most polluting1

In the past 10 years, websites have become 320% heavier — with the average page weighing 2MB2.

Although ever increasing internet speeds have made it unnoticeable to most visitors, there's a cost to that: the heavier the website, the higher its CO2 emissions.

As builders and lovers of this world wide web, we want to do better.

And give you insights to help you reduce them

Our carbon analytics dashboard provides you with everything: from page insights that show where you have leaks, to strategies you can implement to reduce your emissions.

Optionally, you can remove what you can't reduce

The IPCC concluded that billions of tonnes of CO₂ a year need to be captured and buried for us to achieve our climate goals. 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.

Finally, raise awareness with your users

Your websites are used by hundreds, thousands, maybe millions of people—your choice will not only immediately make a positive change, but influence others to do the same.
