They say that numbers don’t lie… but what if we are looking at the wrong numbers to begin with?

On today’s episode of Green IO, Gaël is joined by Cathleen Berger who is here to help us decipher why accurate emissions reporting is so crucial, and why Big Tech continues to make big mistakes when it comes to the figures they release.

Because as the former Head of Sustainability at Mozilla, a lecturer at the Friedrich Schiller University and the head of research and policy for the Deputy Chair on the Digital Committee of the German parliament it’s safe to say that Cathleen knows a thing or two about why accurate data matters.

During this conversation, Gaël and Cathleen also talk about:

Why Big Tech might not want to disclose everything
What the numbers say (and what they’re hiding)
Is anyone seriously following the GHG protocol
Present-day issues with emissions disclosures
Techniques used to conceal important info
Who’s doing things right (and who’s not)

And much, much more.
