IMO, carbon reductions, etc, will ultimately be enforced (forced) by Nature and reality.
Actually most treaties are upheld fairly well, either because doing so is in the interest of all the signers or because the benefits of cheating are not worth the international tensions that would be created.
In terms of climate negotiations the Montreal Accord on CFC's has been a nearly complete success, partly because it had a long phase in time for lesser technologically advanced nations to adapt as they could instead of having to go cold turkey and invest a large sum up front.
