During the last couple years, the carbon emission trading market experienced a boom :

As you can see, the European Union Emission Trading Scheme (EU ETS) contributes the most to the overall value of transactions. Since 2005, some 10,000 large industrial plants in the EU have been required to buy and sell permits to release carbon dioxide into the atmosphere. An ETS enables companies that exceed individual CO2 emissions targets to buy allowances from ‘greener’ ones to help reach the EU’s targets under the Kyoto Protocol. In other words, the EU ETS is a international trading system for CO2 emissions. In the meantime, the EU improved the system. Firstly, because of over-allocation of allowances, the member states decided to lower the total amount of allowances (for the period starting in mid-2008). Furthermore, thanks to an overall review and evaluation of the system, some changes were approved by the member states in December 2008. Among others, the member states agreed that a higher percentage of allowances will be auctioned by 2013. Also by 2020, the EU will ‘cap’ the total EU industrial emissions at 21% below 2005 levels. With these kind of changes in mind, you could expect the price of carbon credits to rise again in the future.
Let us now turn to the American carbon market. Last week, I saw an interesting article at WallStreet Technology : ‘Is carbon trading the next big thing ?’. I would like to quote some parts of it :
The fledgling U.S. carbon credit market, currently a $100 million-plus business, is poised to skyrocket if The American Clean Energy and Security Act of 2009, which recently was passed by the House, makes it through the Senate. The bill would limit, or “cap,” the amount of carbon emissions that companies can produce each year. Under the bill, sponsored by Representatives Henry Waxman (D-CA) and Edward Markey (D-MA), firms that produce more greenhouse gases than they’re allowed would be able to buy credits from companies that have produced fewer emissions than they’re allotted, creating a large market for carbon credits. President Obama has estimated that more than a half-trillion dollars’ worth of carbon credits will be auctioned in the first seven years after the bill is enacted.
As you can see, the ‘American Clean Energy and Security Act of 2009′ would impose a quite similar cap-and-trade system as currently being employed in Europe. For the moment, only a voluntary carbon credit trading market exists in America.
The European carbon market has been growing quickly; the U.S. market still is in its infancy. Trading activity in the European Emissions Trading Scheme grew by 54 percent in the first quarter of 2009 compared to Q4 2008, reaching $28 billion, according to Carbon Finance. This represented 84 percent of the world’s carbon market in terms of value and 78 percent of its volume. Carbon trading in the U.S., on the other hand, made up only 3.7 percent of the trading volume and 1 percent of the value of the global carbon market.
What can be expected in the future ?
Even as firms build out their carbon credit trading capabilities, the market is expected to reach significant levels fairly quickly. President Obama has predicted that about $646 billion worth of carbon credits will be auctioned in the first seven years of the mandatory cap-and-trade system in the U.S.; others have suggested the number could be two or three times that. Trayport’s Pejman notes that once the legislation is passed, there will be a race to the market. “Whoever is already in production will have a tremendous advantage over those that are scrambling to get ready,” he asserts.
To finish, the price evolution. As an example, I took a graph of the European Climate Exchange. The current spot price of EU permits is around €14…but probably will rise again in the future.

(BTW, the carbon market is also mentioned as one of the next bubbles in a ‘famous’ article about an investment bank. I didn’t feel the need to mention this article again but most of you probably know which one I am referring to.)
