I liken this to the Paris Agreement that Trump backed us out of. We can't continue to pretend that what the rest of the world does doesn't matter, that's the bottom line of that accord, it all sounds good on paper but all it does is manipulate the US into meeting more regulatory demands that are proving counterproductive if we have to pay other countries to do the same without a guarantee there will be positive results and more than just another promise of financial commitment down the road. The US put one hundred million down to start the process with a guarantee of another three hundred million....but what about the other countries? All those countries obligation was was to agree to try and reduce emissions but they didn't have to guarantee a reduction nor did they put money into it. As a matter of fact China had already surpassed their quota of reduction two years prior...basically when they came away from that accord all it did was give the world an impression that everyone was in agreement that something had to be done about the environment and protecting it but it didn't hold anyone accountable to guarantee's of reductions. There really was no personal responsibility involved.
