Webinar recording – How to make your website more sustainable



About the webinar

Did you know that a whopping 3.7% of global greenhouse gas emissions are created by the internet and its supporting network and systems? This is broadly equivalent to the emissions created by the aviation industry. Internet emissions are predicted to double by 2025, as more people come online and digital services increase. We can all do something to address this.

In this one-hour Q+A webinar, website Tech Champion, Andy Leitch, is in conversation with Tom Greenwood – a leading voice in the campaign to make websites and digital activity more sustainable.

You will learn:

  • Why web and digital sustainability matters
  • How to judge if your website is eco-friendly
  • Practical tips on how to make your website greener and reduce your digital carbon footprint
  • To consider sustainability for your ongoing digital activity
