This week, the Senate will again hear testimony on the state's proposed cap-and-trade legislation, designed to reduce greenhouse gas emissions. In the first round of hearings, there was a great deal made about the potential economic costs and benefits of cap-and-trade. Setting those aside for the moment, there was an assumption that,whatever the cost, cap-and-trade will work to reduce CO2 emissions. In fact, the evidence shows that it is unlikely to do so.
Ecology Director Jay Manning testified twice before the Legislature this year that Europe was likely to meet its CO2 reduction targets using the cap-and-trade system under the Kyoto Protocol. A quick look at the data from Europe shows this is not true. The most recent data, found on the EU Environment Agency’s web page, show that the emissions reductions they have achieved under cap-and-trade are almost nonexistent.
First, while the Kyoto Protocol measures emissions against 1990, the agreement was signed in 1997 and has been in effect since then. Emissions reductions prior to 1997 are due to other factors including the collapse of the communist bloc and the economies of E. Europe in the early 90s and the UK’s switch from coal to natural gas in the early 90s. Thus, cap-and-trade is only responsible for emissions reductions since 1997. From 1998 to 2006 (the most recent year for which data is available), emissions of greenhouse gases have declined only 0.42%. Nearly 90 percent of CO2 emissions in Europe occurred before Kyoto was signed. The note below, which highlights this point, is taken from the EU report.
Second, for Europe to meet the goals it would require a sudden reduction of 5 percent in CO2 emissions during the final five years of the protocol (i.e. from 2007 to 2012). As you can see in the chart below, following existing measures, Europe will fail to meet the targets. Adding “additional” measures gets them close but still fails. Only when Europe aggressively pursues carbon offsets from China and elsewhere do they meet the target. Ironically, the EU recently tightened the rules on offsets, meaning that such offsets are likely to decrease, not increase.
Additionally, as is evident, the 5-year average of emissions, represented by the black line, would leave Europe with emissions only slightly below 1990 levels, missing even the projections for the existing measures. Only a sudden downturn not evident at any time up to this point would leave Europe in compliance. The argument that EU is on track to meet their goals is wishful thinking at best. There is no reason to believe that the WCI cap-and-trade system would be any different.
Finally, as a result of the failure of Kyoto in Europe, countries are facing a large penalty,on the order of $46 billion. This cost will be paid by the economies and taxpayers of Europe.
Put simply, cap-and-trade has not lived up to its promise and alternatives are needed. Whatever you believe about the economic merits or disadvantages of cap-and-trade, if it doesn't work, why would we adopt it?
