"Believe it if you like".
Is there any legal power robust enough to compel these companies to publish this information? And then prove it?
Because otherwise they'll only tell you what they think you want to hear.
As for the veracity of the current platitudes, they've obviously perfected Nuclear Fusion or harnessed a black hole - everything is up, exponentially in many cases, except the carbon produced.
30 years ago I flew out to Italy to start a new contract. To simplify travel arrangements the company had asked me to meet another couple of contractors at Stansted for the outbound flight. Being young and naive, over a quiet beer in departures I mentioned this was my first proper contract for the company, and had only been in that line of work for 6 weeks. This seemed to throw them off balance - after a brief pause the more talkative one muttered they'd been on the job around 6 months, and the conversation turned to the night shifts they had been on the previous week.
When we landed and met up with another crew (who had been working out there for a couple of months) I discovered my two new colleagues must have been abducted by aliens - for their 6 months experience pre-flight had matured into some 6 years on landing.
I think whoever writes climate PR for Amazon, Google, Microsoft etc must have also been on that flight.
