In a major break from the policy of the Bush administration, President Obama has announced that the US government will regulate greenhouse gas emissions. The US Environmental Protection Agency has found that CO2 emissions pose a ‘threat to public health and welfare’. This finding allows regulation to be imposed.
At the end of March the Democrats in the House of Representatives released a draft climate change Bill. Central to this would be a system of tradable permits. ‘Under this program, covered entities must have tradable federal allowances for each ton of pollution emitted into the atmosphere.’ (See 4th article below.)

Questions
- To what extent is the EPA ruling compatible with the bill proposed by the Democrats?
- Is a ‘cap-and-trade’ system (i.e. tradable permits) the best way of dealing with climate change?
- What lessons can the USA draw from the European Emissions Trading Scheme in designing its own tradable permits scheme?
The ‘tragedy of the commons’ refers to the overuse of common land. If people can freely graze their animals on such land and have no responsibility for maintaining it, then the land will be overused and everyone will suffer. The problem is that the benefit of using the land occurs to the individual whereas the cost is collectively incurred.
There are many modern examples of the tragedy of the commons and the articles below look at some of them. Perhaps surprisingly, not all cases of the use of common resources end in tragedy; some common resources are used sustainably. A more thorough analysis must involve deeper questions of human motivation and behaviour.

Questions
- Explain how the tragedy of the commons arises and give some examples other than common grazing land.
- How and why does the tragedy of the commons occur in information technology? Consider the benefits and costs of the ‘fix’ to the problem advocated in the first linked article.
- Does the case of Wikipedia (see the third linked article) disprove the proposition that common resources will be overused?
- To what extent is free access to content (music, newspapers, videos, books, etc.) a tragedy of the commons? Is the only solution to devise an effective charging model that rewards content creators?
The G20 countries meet each year. Normally their meetings are full of fine words resulting in little action. But at a summit in London on 2 April 2009, the fear of a deepening global recession focused minds and a package of measures worth over $1 trillion was agreed to stimulate trade and growth. This included $750 billion for the IMF to help economies in severe difficulties, $250 billion for financing world trade and $100 to multilateral development banks (such as the Asian Development Bank) to provide extra aid to the poorest countries.
The extra money for the IMF would include $500 billion of loans from member countries and £250 billion in new money – a form of international quantitative easing. This new money would be in the form of ‘special drawing rights’. These are denominated in dollars and are created by the IMF to be drawn on by countries in difficulties.
There was also agreement to tighten financial regulation and to resist protectionism. A ‘Financial Stability Board’ would be set up and work with the IMF to design a strengthened regulatory system for banks and other financial institutions and for financial markets and instruments.
The following articles look at the agreement and its likely effects.

Peak oil is an important concept for the oil market. Peak oil is the moment in time at which the maximum extraction rate of oil is reached. From this moment on, production will decline. Basic economics tells us that the oil price will tend to rise from then on (unless demand were to fall faster), but the complexities of the demand and supply for oil dictate that there will not be a simple inverse relationship between the supply of oil and the price. In the articles below George Monbiot interviews Faith Birol, the Chief Economist of the International Energy Agency and the Asia Times article looks at the extent to which world economies rely on oil for energy and other needs. Oil prices may be low at the moment and the market may be awash with excess oil and not enough demand for it, but this is a short term phenomenon; there is little doubt about the long-term direction of the price.

EU leaders at a Brussels summit have agreed a plan to cut emissions. This will involve the 27 EU countries cutting greenhouse gas emissions by 20% by 2020 compared with 1990 levels. The aim is also to try to raise renewable energy sources to 20% of total energy use. The package has become known as the 20/20/20 package, but scientists have already argued that these measures may not be sufficient to prevent serious climate change.
