This presentation, plus workshop, was shared at the Cleanweb UK Meetup on February 22, 2016 at the Impact Hub Westminster in London. It's a walkthrough the IYWTo platform we are building to map and promote digital projects to act on climate change. And an explanation of why we believe web innovation has a fundamental role to play in driving behavioural changes to tackle climate change. The IYWTo is illustrated by a series of examples. Two exercises close the presentation. We worked as a group to address the issue of speeding up the cleanweb mapping process and of engaging people with the cleanweb on the emotional level.
