Our Sustainable Website

At Climate Tech Partners, we recognise we have a responsibility to protect the environment. That’s why we’ve teamed up with Wild Tree Digital to build a low-carbon site.

For each homepage view, our website uses 0.36g of carbon, compared to 0.8g of carbon for a standard website. That means for every 1000 views we’re saving the equivalent of keeping a light bulb on for 12 hours!

But that’s not all! Our website is also hosted on a server powered by renewable energy, further reducing our environmental impact.
