So what if China produces goods in a dirty manner? How is this the UK's problem? This is a classic case of moving the goalposts. The UK has achieved carbon emission reductions without negatively impacting the standard of living, but of course that is not sufficient for the climate activists, is it, as it is the modern standard of living that they truly have an issue with.
Perhaps the climate activitists don't realize is that most of the population doesn't want to live "one with nature", and we are extremely loath to give up the creature comforts of modern urban living. Much of climate moralizing nowadays reminds me of the Temperance League at the turn of the century.
