Carbon emissions trading involves the trading of permits to emit carbon dioxide (and other greenhouse gases, calculated in tonnes of carbon dioxide equivalent, tCO2e). It is one of the ways countries can meet their obligations under the Kyoto Protocol to reduce emissions and thereby mitigate global warming.

107 million metric tonnes of carbon dioxide equivalent (tCO2e) have been exchanged through projects in 2004, a 38% increase relative to 2003 (78 mtCO2e).*

Operation

A country (or group of countries) caps its carbon emissions at a certain level (this is known as cap and trade) and then issue permits to firms and industries that grant the firm the right to emit a stated amount of carbon dioxide over a time period. Firms are then free to trade these credits in a free market. Firms whose emissions exceed the amount of credits they possess will be heavily penalised. The idea behind carbon trading is that firms that can reduce their emissions at a low cost will do so and then sell their credits on to firms that are unable to easily reduce emissions. A shortage of credits will drive up the price of credits and make it more profitable for firms to engage in carbon reduction. In this way the desired carbon reductions are met at the lowest cost possible to society.

Business opinion

With the creation of a market for trading carbon dioxide emissions within the Kyoto Protocol, it is likely that London financial markets will be the centre for this potentially highly lucrative business; the New York and Chicago stock markets would like a share (which is unlikely as long as the US rejects Kyoto).The European Union's [http://europa.eu.int/comm/environment/climat/emission.htm European Union Greenhouse Gas Emission Trading Scheme (EU ETS) began operations on 1 January 2005.

23 multinational corporations have come together in the G8 Climate Change Roundtable, a business group formed at the January 2005 World Economic Forum. The group includes Ford, Toyota, British Airways and BP. On 9 June 2005 the Group published a statement stating that there was a need to act on climate change and stressing the importance of market-based solutions. It called on governments to establish "clear, transparent, and consistent price signals" through "creation of a long-term policy framework" that would include all major producers of greenhouse gases.

Controversy

There are critics of the schemes, mainly environmental justice NGOs and movements who see carbon trading as a proliferation of the free market into public spaces and environmental policy-making. They point to failures in accounting, dubious science and destructive impacts of projects upon local peoples and environments as reasons why trading pollution rights should be avoided. Instead they advocate making reductions at the source of pollution and energy policies that are justice-based and community-driven.
