As I've said, this is being grabbed enthusiastically bt government because it's a money earner.
You've said that twice and you are plain wrong.
In the first place, it hasn't been grabbed enthusiastically by the Government. It's more like, successive Governments in the UK and the World have had to be dragged over many years, kicking and screaming, to recognise what science has been unambiguously telling us for some decades: That if we don't curb CO2 emissions and address other environmental problems, we are headed for disaster. Even today, various political parties and some Governments across the World continue to deny the overwhelming evidence from science - as it appears you are also doing. And even where Governments - like here in the UK - acknowledge the problem, they seem very reluctant to take sufficient action to address it properly.
And secondly pretty much everyone I know who is involved with politics and is concerned about and trying to combat climate change is doing so because they believe it's the right thing to do. Nothing to do with earning money. In fact, in the short term, on balance it costs rather than earns money because of the investment needed in new technologies etc. (In the long run, there'll be a financial benefit in looking after the environment just from avoiding the disastrous effect that unmitigated global warming will have on most countries' economies).
