It's interesting to see how Big Tech giants like Google and Amazon handle their climate claims. On the surface, Amazon looks like the winner by meeting their clean energy targets early. But dig deeper, and it's clear they're heavily relying on carbon credits and RECs, which often don't translate to real-world emission cuts. Google's shift away from these and focus on direct solutions seems more genuine. Are these 'net-zero' claims just creative accounting, or are they paving the way for real change?
