An Energy Bill with a Catch

Yesterday, a monumental energy bill was passed in the House. While liberals and conservatives are shouting out praise or disapproval, respectively, few have looked past party lines to gauge the real effects of the bill.

The bill is attempting to achieve one main objective which is a 17% reduction in economy-wide greenhouse gas emissions by 2020. The proposed strategy is a cap-and-trade system with large amounts of domestic and international carbon offsetting opportunities. There are provisions in the bill which will assist and mitigate the primary objective such as renewable energy requirements on utilities, energy efficiency incentives for consumers and businesses, grants for green jobs, and research and development on carbon sequestering technologies.

Though I support a bill to mitigate use of carbon-producing technologies, I cannot say with confidence that this bill will be able to achieve that. A system of cap-and-trade can be effective but is easily sabotaged with offset credits. The theory behind cap-and-trade (in this case) is that the government will set a limit on CO2 emissions that can be released into the air and then issue permits to businesses to pollute in the specified range. This provides economic incentives to businesses to reduce emissions for whom it is inexpensive to adopt cleaner air technologies. These businesses can then sell their permits to businesses that cannot easily adopt clean air technologies. So far so good. But then the offsets begin. This allows a business to pollute above their permit allowance so long as they invest in carbon offsetting activities. These carbon offsetting activities could be planting trees in Brazil to encouraging US farmers to adopt energy saving farming practices. Businesses will then invest in the offsets until the cost of offsetting reaches the cost of buying permits. The problem is that offsets reverse any intention and effect that capping has - i.e. it is the purpose of the cap to reduce emissions but offsets allow firms to pollute past the cap as long as they pay for it.


Economically, this makes sense. Those who pollute must pay. But the goal of the bill clearly specifies a 17% decrease in greenhouse gas emissions by 2020. If the goal is a reduction, then offsets will not help. If the goal instead is to increase the cost of polluting to reduce consumption, then cap-and-trade with offsets is the right system. it might seem that in both cases the reduction in emissions is realized, but in the first system, without offsets, the amount of emissions is set and final, while the with the offsets, the amount of emissions will depend on a multitude of factors such as firm's cost structures, elasticity of demand for that firms products, elasticity of supply of that firm, etc. And this is where it becomes complicated.

Further, though I have not done the research, it seems a bit far fetched to me that planting forests in South America will offset emissions released in the US. On average, maybe this is true, but this isn't statistics where the average rules. This is our air and I want the air I breath in the US to be clean, not clean "on average."
