So just what is a cap and trade system and how does it work? MSNBC has a Frequently Asked Questions page that answers this question. While President Obama signaled his desires in his budget, congress is required to pass the legislation and the details. Many experts are suggesting legislation is unlikely this, however “Powerful Democrats such as House Energy and Commerce Committee Chairman Henry Waxman, D-Calif., have said they would work hard to get legislation passed by this summer.”

Citing lower forecasts in 2009 output along with an increase in the number of firms announcing temporary shutdowns, analysts are scaling back their forecasts for carbon emissions and the price for allowances for those emissions. Societe Generale has cut their forecast for EUAs a third to 17 euros a ton. They went on to say prices could rise to 20 euros by 2012, sharply down from estimates earlier this year that prices would reach 37 euros during this timeframe.

Deutsche Bank believes EU emissions in 2009 could be 10% below 2007 levels. This would push emissions below allowances for 2009. The excess allowances for 2009 can be “banked” for use through 2012 and the forecasted emissions for 2009-2012 remain slightly above the EU carbon allowances. As a result of reduced emissions and smaller shortfall, UN-approved Certified Emission Reductions (CERs) which EU industry can import from developing nations to meet compliance, may be able to meet the entire shortfall. Price estimates for EUAs and CERs clearly indicate analysts believe CERs will set the pricing for EUAs for the next few years.

The good news is EU will be able to meet the allowances under phase 2 with a small “carbon price” in this recessionary period. This is also the bad news, as the lower price reduces the investment per ton of CO₂ available for carbon abatement projects. The net is by 2012, the European Union will have done less and perhaps much less to lower the Green House Gases (GHG) they produce per unit of energy they consume than anticipated when the allowance allocations were set.

With allowances exceeding current emission’s forecast the first auction of allowances in a mandatory US system brought little new information. Keith Johnson at Environmental Capital put it this way:
“But don’t get too excited. The Regional Greenhouse Gas Initiative, or ”RGGI,“ is more likely to start with a whimper than a bang. Prices for the carbon permits are likely to be low, and that will probably undermine the scheme’s plan to force utilities to generate cleaner power.”
