Loose rules on corporations
Lenient rules of energy-efficiency or carbon taxation on corporations would not have much effect.
Such new norms of energy regulations could be enforced, but their inherent costs would simply passed on to consumers, as it’s often the case. For doing nothing, a slight penalty would see corporations doing nothing, as it’s often the case, as they watch the competition doing not much more.
And governments are afraid that doing more could hurt the economy and especially the poor.
