What do you actually want “our government and other governments” to DO? Please be specific.
Well raising a huge amount of money through various new and increased taxes would be a start. Raising corporation tax, fuel surcharges, aviation taxes increasing hugely, etc.
To pay for the creation of fully integrated, sustainable public transport systems in and between all major towns and villages.
Money could also be put into removing older petrol / diesel cars from the road, subsidising their replacement with other forms of transport.
Change planning laws to prevent the development of any new build housing unless it is easily linked to said public transport system. Needless to say, the construction of individual detached houses based on individual car transport would cease immediately: resource-efficient, high density easily-accessed housing only.
Basically, to put the climate change impact of every decision at the top of the list of priorities- above any economic and social benefits.
These are off the top of my head, not carefully worked out plans. The actual steps that need to be taken are probably even more extreme. Sound like real vote-winners, yes?
The government has the power to do many things, make laws, raise taxes etc: if they put it in their manifesto, win an election and thus have a mandate to implement it. But the nature of our political system means they won’t / can’t do anything that threatens or reduces the quality of life of their voters as they won’t win any elections that way. We - the voters - might have an inkling that “the house is on fire” but really it doesn’t currently impact on our lives that much. We hear the fire alarm, somewhere over there, but we’re really comfy here in our lives and we’re not really sure that there is actually a fire (though there are some people making a noise in the street about it) and we’ve just made our tea and sat down to watch Eastenders... we like driving our own cars, we like living in detached houses, we like going on holiday abroad, we like eating food and drinking wine and having hobbies etc. And we aren’t going to vote for any party that proposes to curtail those choices.
