About Us

Every business, just like every superhero, has an origin story and GoCodeGreen is no different

GoCodeGreen’s journey started whilst collaborating on a new web application. During the process our founder asked the pointed question “shouldn’t we be measuring the impact of this software as we build it?”

There was much nodding and some scratching of heads amongst the team, leading to some investigation and the realisation that we should be and that no-one was measuring its environmental impact. Thus GoCodeGreen was born.

Now 2 years later, we are a 2 times Earthshot prize nominee, partnered with the ITU, the United Nations specialised agency for Information and Communication Technology; and a Certified B Corporation.
