Al Gore’s contribution to the global climate change debate is not in question and he has, along with the IPCC, been awarded the 2007 Nobel Peace Prize for his work in raising awareness. If you haven’t seen his film “An inconvenient truth” then do get hold of the DVD – it may just be the most interesting PowerPoint presentation you will ever see! However, does he really understand the nature of the debate? The article below suggests that he has not yet taken account of the most fundamental trade-off in dealing with climate change – the trade-off between our own quality of life and that of our descendants in the future.

Save the earth in six hard questions MSN Slate (22/10/07)

Questions

1. Explain what is mean by a trade-off “between the quality of our own lives and the quality of our descendants’ [lives]”.
2. What is meant by the term ‘risk-averse’ and how is this relevant in the climate change debate?
3. Consider the questions raised by the article. Discuss how relevant the conclusion reached is in the light of these questions.

In its first report on the impact of bio-fuels, the United Nations (UN) has warned that such fuels may increase poverty in developing countries and have a wider environmental impact than has in the past been suggested. With oil prices at a record high and with climate change pressures, much of the developed world has adopted targets for bio-fuels, but environmentalists have warned that the rush to grow the raw materials for bio-fuels may be more damaging to the environment than the fossil fuels they will replace.

Questions
1. What are the external costs and external benefits resulting from the use of bio-fuels as opposed to fossil fuels?
2. Using diagrams as appropriate, show the impact of increased use of bio-fuels on the social equilibrium in the market for fuel.
3. Assess policies that European governments could put in place to ensure that the move towards increased use of bio-fuels has a positive environmental impact.

You do perhaps need to check the date for this story, but once you have established that it wasn’t written on April 1st, you can start to take it a little more seriously. An alliance of an American oil company and food producer is to turn pig fat into diesel fuel. The fuel will apparently have the same chemical properties as diesel but a lower carbon dioxide content and zero sulphur, so should be beneficial for the environment the companies argue.

Questions

1. Using diagrams as appropriate, compare and contrast the environmental impact of conventional diesel and the new pig fat bio-diesel.
2. Discuss the extent to which the new pig fat diesel will be better for the environment than conventional diesel.
3. Evaluate two policies that the government could implement to encourage the use of alternative fuels like the new pig fat bio-diesel.

In what is being heralded as a historic deal, the EU has reached agreement with the USA on what is termed an ‘open skies’ deal. This will allow EU-based airlines to fly from anywhere in Europe to anywhere in the USA and US carriers can operate to any European destination. So what will this deal mean for travellers, the environment and the airlines. The articles below look at the issues and also at the detail of the agreement, which still maintains many of the previous limitations on airlines and their ownership.

Questions

1. What criteria should be used to assess the success of the ‘open skies’ deal?
2. Assess the extent to which the ‘open skies’ deal will increase the level of competition in the transatlantic market for air travel.
3. Discuss the options available to the EU to increase competition further in the market for air travel.

March 2007 has seen a lot of activity in government circles relating to the environment and environmental legislation. The EU has agreed a renewable energy target for all members while the UK government has released its own climate change bill. The Carbon Trust has then released a one-year pilot of a carbon labelling scheme, with Walkers Crisps being the first brand to bear the carbon labels. The aim is to increase consumers’ awareness of the carbon footprint of the goods they are buying. The articles linked below look at all these issues.

Questions

1. Explain the difference between private costs and external costs. Identify five external costs that arise from the generation of electricity by conventional means.
2. Using diagrams as appropriate, show the impact on the market for energy of increased use of energy generated from renewable sources.
3. Evaluate the likely effectiveness of the carbon labelling scheme introduced by the Carbon Trust.
