“Cap & Trade”– An introduction market-based approaches to pollution reduction

Inside Obama’s Green Budget – Forbes.com

Some say that Global Warming may be the greatest market failure of all. This podcast was originally broadcast in January of 2007 while George Bush was still in office. The commentator claims that global warming is “nothing but one giant market failure”, arguing that the United States therefore must get serious about tackling the problem.

The allocation of resources towards carbon emitting industries has almost undoubtedly contributed to the warming of the planet over the last half century. Only recently have governments begun taking active measures to reduce the impact of industry on the environment through greater regulation of polluting industries, employing corrective taxes in some instances and market-based approaches to pollution reduction in others.

US President Barack Obama, unlike his predecessor, appears to be serious about correcting the “market failure” represented by global warming:

Obama’s budget, announced Thursday, looks to fund a host of new energy programs, from carbon sequestration to electric transmission upgrades. It would also provide the EPA with a $10.5 billion budget for 2010, a 34% increase over the likely 2009 budget. Nineteen million dollars of that would be used to upgrade greenhouse gas reporting measures.

The Interior Department would get $12 billion for 2010. The agency would use part of the money to asses the availability of alternative energy resources throughout the country.

Funding comes from elaborate carbon “cap and trade” program, which puts a price on emitting pollution and is the core of Obama’s plans. Starting in 2012, the government would sell permits giving businesses the right to emit pollution, generating $646 billion in revenue through 2019.

During those years, the number of available permits would gradually decline, forcing businesses to buy the increasingly scarce, and costly, rights to pollute on an open market. Obama hopes that the rising cost of permits will encourage businesses to invest in clean technologies as a cheaper alternative to meeting pollution mandates, helping to cut greenhouse gas production to 14% below 2005 levels by 2020.

Below is a diagram that illustrates precisely how the Obama cap and trade plan is meant to work. Notice that between 2012 and 2020 the cost to firms of emitting pollution will increase dramatically, while at the same time the total amount of carbon emissions in the US economy will fall due to regular reductions in the number of permits issued to industry.

The Obama cap and trade scheme is not the first experiment with such a market based approach to externality reduction:

Europe established such a market in 2005. But some E.U. governments allocated too many credits at the outset, causing the value of some permits to fall by half and making it relatively easy for large polluters to simply buy credits rather than cut emissions. Overall emissions grew in 2005 and 2006. In 2008, E.U. emissions dropped 3%; 40% of that drop was attributed to the carbon trading scheme.

Europe’s cap and trade program took a few years before it began having any noticeable impact on the emission of carbon by European industry. While unpopular among the firms who are forced to pay to pollute, the fall in emissions in Europe shows that a market for carbon may be effective in forcing firms “internalize” the costs of carbon emissions, which until now have been born by society and the environment in the form of the negative effects of global warming.

Discussion Questions:

  1. Why do you think tradeable pollution permits are more politically viable than a direct tax on firms’ carbon emissions?
  2. Why did Europe’s carbon emission permit market fail to reduce emissions over its first couple of years of implementation?
  3. Is making firms pay to pollute a good idea in the middle of a recession? Do you think that we should even be worrying about the environment when millions of people are losing their jobs and entire industries are struggling to survive?
