Really well written and well argued, many thanks for sharing Tom. I love your point on climate action over climate reporting.

Have you come across other metrics/ways to measure aside energy use, data load or carbon footprint when it comes to digital environmental impact? (Thinking water and land depletion due to cooling of data centres, but doesn’t seem that codified yet?)

Thanks Tom. Like you I have been involved in assessing corporate and personal carbon emissions since before BP/Ogilvy & Mather first coined the "carbon footprint" term - indeed I wrote an online carbon calculator for the National Energy Foundation here in the UK as far back as 1999. However, I'm perhaps less concerned than you are. It's a useful concept, especially for explaining to people that their climate impact extends beyond their immediate use of energy; I suspect that one of BP's motivations originally was to deflect people away from just looking at direct (Scope 1) emissions from using petrol and diesel to the wider impacts (no less self-serving, of course, than to try and shift responsibility!) We need to tackle emissions from both ends - from the demand side (is it OK for me to fly halfway round the world twice a year on holiday?) AND the supply side (should we be building a third runway at Heathrow to increase capacity?)

I wholly agree that there's a need to move on from measurement & reporting to taking action. But I also subscribe to the old adage (sometimes attributed to Lord Kelvin, though he never used the exact words) that if you don't measure something you can't manage it. So on balance I would want to keep the footprint in the toolbox.

Just don't ask me about carbon handprints!
