China and India will be as impacted by a failure to react as anyone else. Neither are stupid. China is already, by far, the largest producer of electric vehicles in the world.
They will react because they have no choice other than to. When they do it will be very fast and effective. I wish it was happening now, but we cannot as individuals influence that. We can only, via our politicians and the international bodies they participate in, keep up the pressure.
Our position is an opportunity to demonstrate how things can be done and to develop, and export, the technology and methods that achieve it.
Shrugging our shoulders, turning aside and passing the buck to others are the reactions of the selfish and the despondent.
