You could argue that what we have isnt true capitalism, since our current system doesnt include the environmental cost. If we could do that, then the cost of doing things would greatly increase, thus forcing capitalism to be more environmentally friendly.
I dont want to defend capitalism, but there is a potential version of capitalism that could work. Kinda how we use the replicative aggressive function of viruses for healing.
The fact that in the West, right wings are often insane, doesnt mean much. 95% of new coal power plants are built in China. Are they right wing? I think they are but tankies think China is socialist.
Obviously China has immense demand for power and it is in many ways a developing country. They took some measures to reduce the negative environmental effect. Their cities were covered in smog till recently, they had to do something.
But despite that, they still value the growth/wealth of cheap electric power.
