A campaign to introduce a tax on disposable plastic bags in England has been launched by various pressure groups, including The Campaign to Protect Rural England (CPRE), Keep Britain Tidy, the Marine Conservation Society and Surfers Against Sewage. Plastic bags, they maintain, litter streets and the countryside and pollute the seas, where they cause considerable damage to marine life.
They propose a tax of 5p per bag, which would be passed on to consumers. Such a levy has already been introduced in Wales in October 2011. As a result, plastic bag use in Wales has dropped dramatically (see also the full report from the Welsh Government). The Scottish Government and the Northern Ireland Assembly are also planning introducing similar charges.
Many other governments have introduced taxes, charges or bans on plastic bags and many more are considering introducing such measures. Ireland introduced a 15 euro cent charge on single-use plastic bags as far back as 2002 and saw a 94% reduction in plastic bag use (328 per person per year to 21). The charge was raised to 22 euro cents in 2007 after bag use rose to 30 per person.
Other countries have banned plastic bags altogether: some, such as Rwanda and Somalia have banned all plastic bags; others, such as China and South Africa have banned very thin bags; others, such as Italy, have banned non-biodegradable ones.
In the USA, various states or districts have introduced levies and in the EU, where more than four billion bags are thrown away each year, the European Commission will soon publish proposals for limiting the use of plastic bags.
So what are the arguments for limiting the use of plastic bags? Why is it not enough to leave things simply to the market? And if the use of plastic bags is to be reduced, what’s the most efficient way of doing so? Are there any problems with alternatives to plastic bags? The following articles and reports consider these questions?

Questions
- Draw a diagram demonstrating the externalities involved in the use of plastic bags. Show the marginal private and social costs and benefits and the socially efficient level of consumption.
- How would you set about establishing the amount of consumer surplus from the use of plastic bags at a zero price?
- Compare the relative social efficiency of a tax on plastic bags with a ban on plastic bags.
- Would education be an effective alternative to taxing plastic bags?
- Why might it be difficult to get supermarkets and other retailers to agree to a voluntary ban on giving out free plastic bags?
- Why might it be extremely difficult in practice to establish the socially efficient price for plastic bags?
UK Parliament’s Environmental Audit Committee has concluded that the European Emissions Trading Scheme (ETS) is not working as it should. Thanks to a total emissions cap that is too low in a time of recession, the carbon price has fallen. The result is that there is no longer sufficient of an incentive for firms to invest in green technology. As the Financial Times article (below) reports:
The committee has urged the government to consider other measures, such as a floor price for carbon dioxide emissions, which would provide industries with greater certainty over the price of carbon and help to ensure the system of pricing was effective.
The MPs said a price of €100 per tonne of CO2 could be necessary to encourage investment, compared with current prices of about €13.
So is the committee correct? Or is a low price of carbon merely temporary, with firms realising that the price will rise as the European economy recovers? The following articles examine the issues.

Questions
- Explain how the ETS works.
- What determines the price of carbon in the ETS? Why has it fallen in recent months?
- Compare the alternative policy approaches for encouraging green investment.
- What are the advantages and disadvantages of setting a floor price for carbon permits? What would be the effect on the balance of demand for and supply of premits?
- Discuss whether the total number of permits allocated should be reduced (i.e. the cap tightened).
- Compare the relative merits of giving the allocation of permits away with auctioning them.
- Compare the relative merits of a cap-and-trade system with green taxes.
In the second of the linked articles below, Andy Atkins, from Friends of the Earth, argues that the European Emissions Trading Scheme (ETS) has failed to make any substantial cuts is emissions and is creating the opportunity for carbon traders to become very rich in increasingly complex financial products based on carbon. “This risks the development of sub-prime carbon and financial crisis – with a double whammy this time of environmental catastrophe to match.” He thus argues for alternative methods of reducing carbon, such as green taxes, tough regulation and government investment in green technology
But is the ETS a failure? In the third article, Alexandra Galin, from the Carbon Markets & Investors Association, argues that the second phase of ETS (2008–12) is much more successful than the first (2005–7) and that substantial carbon reductions have been achieved. Her argument is that a carbon trading scheme’s success in cutting carbon emissions does not depend on the trading system, but on the tightness of the cap. In other words, in a ‘cap-and-trade’ system, it is the cap that reduces emissions; the trading simply achieves the reductions in the most efficient way.

Questions
- Explain how the European Emissions Trading Scheme works.
- What are the advantages and disadvantages of the ETS as a means of reducing carbon emissions?
- Compare theses advantages and disadvantages with those of green taxes.
- How does the market price of carbon traded within the scheme reflect the toughness of the policy? What else might the price reflect?
- What is likely to happen to the carbon price in the coming months? Explain.
In a surprise move, the Tories have announced plans to tax air travel as part of their environmental policy. It was no surprise to hear the airlines criticise this, but disquiet about this policy has been expressed in traditional Tory circles and it amounts to a significant departure from the past for the party. Are they just flying a kite, or is this a serious policy initiative?

Questions
| 1. |
Why might a free market in air travel not result in an optimal number of flights. |
| 2. |
Discuss the likely effectiveness of the tax on flying for reducing the demand for air travel. (You should consider the likely value of the price elasticity of demand in your answer.) |
| 3. |
With the use of appropriate diagrams, assess the likely impact of the tax on flying on the equilibrium level of price and output in the market for air travel. |
