Global Warming Plan Is Full of Hot Air

IN RECENT YEARS, the U.S. debate on global warming policy has been stymied by the unachievable goals of the Kyoto Protocol. Cutting U.S. emissions by one-quarter in barely a decade, as agreed in 1997 at Kyoto by the Clinton administration, was never politically feasible.

Now the Bush administration, nearly a year after pulling out of the Kyoto Protocol, has finally announced its own plan for global warming. It takes a few important steps forward, but it falls far short of a grand strategy that would set ambitious long-term goals and a serious plan for achieving them. One of the important advances in the new Bush plan is that it offers a better way to measure progress on solving the global warming problem. It sets goals in terms of "greenhouse gas intensity."If the economy grows more rapidly than emissions, then the ratio declines. The administration seeks an 18-percent reduction in intensity over the next decade.

By contrast, the Kyoto approach would require the United States and all other industrialized nations to regulate their total quantity of emissions to exacting targets during brief five-year periods. Thus the Kyoto approach unwittingly pitted advocates of economic growth against those who sought environmental protection, especially in the United States. Emissions soared as the U.S. economy grew rapidly in the 1990s, and it became ever harder to devise an economic plan for meeting the Kyoto limits.

The truth is that policymakers are not able to plan compliance for Kyoto-style targets because they don't really have much control over the short-term volume of emissions. Governments can implement policies such as fuel economy standards or tax credits for carbon-free fuels, but these are most effective only over long-time periods. By putting a spotlight on trends in greenhouse gas intensity over long periods of time, the new approach better matches goals with the real leverage available to policymakers.

The administration's plan would also invest more in scientific research on global warming. And it wisely pumps new money into research on energy technologies, such as fuel cells, that may allow future generations to move beyond fossil fuels.

But the weaknesses in the plan are severe.

First, it is exceedingly modest. The planned cut in greenhouse gas intensity - less than 2 percent per year compounded over the next decade - sounds like a lot. But viewed from the long perspective of economic history, it is trivial. In the 19th century, U.S. greenhouse gas intensity rose as industrialization accelerated the burning of fossil fuels even more rapidly than the economy swelled. Greenhouse gas intensity peaked in 1917 and has been declining ever since.

New economic activities - such as banking and software design - do not require the same level of emissions as old energy-intensive industries such as steel production. The Bush plan does little to accelerate this decoupling of economic growth from greenhouse gas emissions. Even the planned cut in intensity will not stop the growth in total emissions.

A second weakness in the Bush plan is a lack of clear binding schedules that would require companies to control gases they emit, which would give them an incentive to invest in new technologies. Clear signals are necessary because the power plants, cars and factories we build today will constrain our freedom to control emissions in the coming decades. Rather, the plan only encourages firms to implement voluntary reductions in emissions. Firms that make cuts would earn credits honored in the future.

This voluntary system could accelerate development of a binding emission trading system for the United States, which would be a welcome step forward. In the interim, the voluntary approach will create a snake pit of promises and technical problems that will hamper serious future efforts to control emissions. A complicated and intrusive scheme to review every project might offer answers, but it would be costly and bureaucratic.

Third, the new plan fails to solve many of the problems that rightly led the Bush administration to criticize the Kyoto framework. Last spring the president lambasted Kyoto for setting arbitrary short-term targets. His plan is little different - it sets vapid short-term goals, yet is silent on long-term trajectories that matter most. Nor does the plan offer a credible reply to the administration's critique that Kyoto fails to require participation by developing countries. The administration's plan offers some additional funding to entice developing countries, but the sum is much smaller than the schemes that other nations are already developing within the Kyoto framework.

The good news is that the administration has broken its silence on the important problem of global warming and offered a reasonable framework for debating policy goals. The bad news is that it offers little else. The solution is to set more meaningful, long-term goals, binding clear incentives for firms to reduce emissions and serious programs for engaging developing countries.
