I wonder whether the agreement has any penalty clauses, or whether it's just another political ploy. In either case, if EU member states actually try to achieve these objectives by making it harder to do business, it would be foolish to imagine that other nations would "give them a break". Whatever additional pollution controls are put in place will need to be done with the cooperation of business.
The larger issue, however, remains whether greenhouse emissions controls are good policy from an environmental point of view. The so-called scientists who are waving the banner of man-made global warming have stepped outside their proper role as scientists and into public advocacy. Their climate models have utterly failed to predict future events, indicating that they do not have a grasp of the complexity of the Earth's climate. Why is this important? Well, let's consider our objectives.
Do we want the global climate to remain about the same as it is now, or do we want it to operate as it did when humans had less impact on the environment? If the objective is the second, then we have to recognize that significant climate swings will continue to happen, as they done in the past. This has included ice ages as well as much warmer periods. This is what Earth's climate does without human intervention. If, however, we want the climate to remain about the same, then we have to *meddle* with natural processes, and how many are confident that we know enough to do that? (I refer again to the predictive climate models that fail to predict climate, as an example.) Presumably, if we are going to meddle with climate, to keep it about the same, then we will want to reduce greenhouse gasses at one point, and increase them at some other point in the future. Are we truly 100% confident that reducing greenhouse gasses is the right thing to do at this point? If we knew the Earth was due to enter another Ice Age, would this choice remain the same? It seems to me that we ought to put the science back into "climate science" before we start messing with it. That's like trying to fix a jet engine without a repair manual, while it's in flight.
