Green tech boom looms but poor nations risk being eclipsed: U.N.

It's hard to see how some of these technologies can really be called green innovation. Blockchain is famously energy intensive but some are even a threat to the environment, like nanotechnology.

Moonraker is correct. Take 5G. Is it green? No. Although faster, is uses more power. Now add in the cost in e-waste of everyone eventually dumping their 4G phone for a 5G one. Each xG transition, like each new generation of iPhone costs the environment - units and batteries. And then there is the greater usage of devices on a network that is supposedly going to allow users to do more.

For developing countries, simply 'developing', and all that it entails, is often a huge hit to the environment.

Their fundamental assertions are wrong.

quote: a patents waiver to promote the transfer of climate change-related technology.

That would be a good thing in terms of fairness, but again, it would encourage things that would have a greater impact on the environment.
