The global green treaty movement to outlaw climate change is the most egregious folly to seize the world’s imagination since the Kellog-Briand Pact outlawed war in the late 1920s. The idea that the nations of the earth could agree on an enforceable treaty mandating deep cuts in their output of all greenhouse gasses is absurd. A global treaty to meet Mr. Gore’s policy goals isn’t a treaty: the changes such a treaty requires are so broad and so sweeping that a GGCT is less a treaty than a constitution for global government. Worse, it is a constitution for a global welfare state with trillions of dollars ultimately sent by the taxpayers of rich countries to governments (however feckless, inept, corrupt or tyrannical) in poor ones.

For this treaty to work, China, India, Nigeria and Brazil and scores of other developing countries must in effect accept limits on their economic growth. The United States must commit through treaty to policies that cannot get simple majorities in Congress — like sending billions of dollars in climate aid to countries like Iran, North Korea, Syria and Pakistan, even as we adopt intrusive and expensive energy controls here at home.

The green plan is a plan for a global constitution because the treaty will regulate economic production in every country on earth. This is a deeply intrusive concept; China, Nigeria, Myanmar, Iran and Vietnam will have to monitor and report on every factory, every farm, every truck and car, every generator and power plant in their territory. Many states do not now have and possibly never will have the ability to do this in a transparent and effective way. Many others will cheat, either for economic advantage or for reasons of national security. Many states do not want their own citizens to have this knowledge, much less the officials of hostile foreign powers.
