EU environmental legislation is beginning to cause problems in the UK. As it prohibits coal-fired power plants from generating power, they will be forced to close. This means that the UK will be forced to rely more on imported energy, which could lead to price rises, as energy shortages emerge.

Ofgem, the energy regulator has said that the risk of a gas shortage is likely to be at its highest in about 3 years time, as the amount of spare capacity is expected to fall from its current 14% to just 4%. Energy shortages have been a concern for some time, but the report from Ofgem indicates that the predicted time frame for these energy shortages will now be sooner than expected. Ofgem has said that the probability of a black-out has increased from 1 in 3,300 years now to 1 in 12 years by 2015.

The government, however, has said that its Energy Bill soon to be published will set out plans that will secure power supply for the UK. Part of this will be through investment, leading to new methods of generating energy. The Chief Executive of Ofgem, Alistair Buchanan said:

‘The unprecedented challenges in facing Britain’s energy industry … to attract the investment to deliver secure, sustainable and affordable energy supplies for consumers, still remain.’

One particular area that will see growth is wind-farms: a controversial method of power supply, due to the eye-sore they present (to some eyes, at least) and the noise pollution they generate. But with spare capacity predicted to fall to 4%, they will be a much needed investment.

Perhaps of more concern for the everyday household will be the impact on energy prices. As we know, when anything is scarce, the price begins to rise. As energy shortages become more of a concern, the market mechanism will begin to push up prices. With other bills already at record highs and incomes remaining low, the average household is likely to feel the squeeze. The following articles and the Ofgem report considers this issue.

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?

The Office for Budget Responsibility has said that the UK Treasury will face a shortfall of £13bn in motoring taxes within a decade. Although car usage continues to rise putting increasing pressure on the road infrastructure, the greener and more fuel efficient cars being produced are driving down the tax revenues generated from motoring.

A report by the IFS has put forward the case for replacing the existing system of taxes on cars and fuel by a new road charging system. If no such change occurs, the IFS has forecast that with more electric cars and hence lower revenues raised from fuel and vehicle excise duties, the shortfall facing the Treasury would require an increase in fuel duty of some 50%. Instead of this, the solution could be to charge individuals for every mile of road they use, with the ‘price’ varying depending on the degree of congestion. For example, at peak times the price would be higher, where as for those in the countryside where roads are traditionally much quieter, charges would be lower. The IFS said:

‘Such a move would generate substantial economic efficiency gains from reduced congestion, reduce the tax levied on the majority of miles driven, leave many (particularly rural) motorists better off, and provide a stable long-term footing for motoring taxes without necessarily raising net additional revenue from drivers.’

Government policy across the world has been increasingly focused on climate change, with targets for emissions reductions being somewhat ambitious. However, many car manufactures who were told to reduce emissions significantly are on the way to meeting these targets and this success is a key factor contributing towards this new road ‘crisis’ that could soon be facing the government. The following articles consider the possibility of a road charging scheme.

My son Andrew Sloman (see also) is currently in Goa. My wife Alison and I went to visit him over half term – our first trip to India. Goa is a beautiful state, with wonderful beaches, fantastic food and perfect weather in February. But inland from this tourist haven lies an environmental disaster caused by the open-cast extraction of iron ore.

This tiny state by Indian standards produces more than 60% of India’s iron ore exports. Whilst, along with tourism, the iron ore industry has been one of the largest contributors to the Goan economy, its environmental footprint is massive. Deforestation and water and air pollution are just three of the environmental externalities.

So should a cap be placed on the amount of iron ore that is mined? Should the industry be taxed more heavily? Should tough environmental standards be imposed on the industry? Or should it simply be allowed to continue, given its large contribution to the Goan economy? Or, at the other extreme, should the industry be closed? The linked article looks at some of the issues. Try to identify, as an economist, what information you would require in order to come to a conclusion to these questions.

Greens’ shout for cap on iron ore mining falls on deaf ears Times of India, Paul Fernandes (28/2/12)

The total EU budget in 2010 was €123 billion. Just under half of this (€58 billion) was spent on supporting agriculture. The programme of support – the Common Agricultural Policy (CAP) – has changed over the years. For a start, despite its being a large proportion of the EU budget, this proportion has actually been falling. In 1980, the CAP accounted for 69% of the EU budget; in 1990 it was 60%; in 2000 it was 52%; in 2010 it was 47%.

The types of support have also changed. The main method in the past was effectively to set minimum prices for various foodstuffs and for Intervention Boards to buy up any surpluses that arose from such prices being above the market equilibrium. Massive food ‘mountains’ resulted. Sometimes these surpluses were dumped on the world market; sometimes they were thrown away; sometimes they were simply kept in storage. Export subsidies and import levies (taxes) were also used to reduce surpluses. This, of course, was highly damaging to farmers in many countries outside the EU, especially in various primary exporting developing countries.

Reforms have taken place in recent years. The most important has been to replace high intervention prices with direct payments to farmers unrelated to current output. Whilst such payments still provide a substantial outgoing from the EU budget, being unrelated to current output, they do not encourage farmers to produce more and thus do not generate surpluses. Prices in most cases are allowed to be determined by the market.

The EU has just announced further reforms. These include:

• Capping total CAP spending at current levels until 2020
• Capping the total payment to any one farm to €300,000
• Relating subsidies to acreage rather than previous output
• Making 30% of the direct payments dependent on farmers meeting environmental criteria.

The following videos and articles examine the proposals and assess their likely benefits, their likely drawbacks and their likelihood of being implemented.

It is widely acknowledged that the supply of oil and gas will eventually run out. As these resources are depleted, prices will inevitably rise. However, with heating and energy bills at extremely high levels, a new ‘resource’ in Sweden has been used to heat buildings: Body Heat!

Hundreds of thousands of people pass through Stockholm Central Station every day and rather than letting the body heat these people generate go to waste, a Swedish firm, Jernhusen, is now ‘collecting’ their heat, converting it into hot water and then using this as a new heating resource. Klass Johnasson, one of the creators of the system said:

This is old technology being used in a new way. The only difference here is that we’ve shifted energy between two different buildings.

The Swedish firm has found that the system is not only environmentally friendly, but it is also good business practice, as it has reduced the energy costs of the block by some 25%, which, during a recession and with high energy prices, is no small thing!

The costs and benefits of such a system will inevitably vary from country to country, but in Sweden’s case, it is a viable method of heating, given their high energy prices and low winter temperatures. They are not stealing the heat from anyone, but are simply converting the excess heat that is already there. Obviously, the fact that the firm owns the station, and also the land between the station and their building, is helpful in ‘transferring’ the energy, but the firm argues that even if this wasn’t the case, it’s nothing co-operation wouldn’t solve. Is this the future of low-cost and low-carbon heating?

At the end of two weeks of often acrimonious wrangling between representatives from 193 countries, an agreement – of sorts – was reached at the climate change summit in Copenhagen. What was this agreement? It was an ‘accord’ brokered by the USA, China, India, Brazil and South Africa.

This Copenhagen Accord contains three elements. The first is a recognition of the need to prevent global temperatures rising by more than 2 degrees Celsius above pre-industrial levels. The second is a commitment by developed countries to give $30bn of aid between 2010 and 2012 to developing countries for investment in green technology and to mitigate the effects of climate change. In addition, a goal was set of providing $100bn a year by 2020. The third is for rich countries to give pledges on emissions reductions and for developing countries to give pledges on reducing emissions increases. Developed countries’ pledges will be scrutinised by the UN Framework Convention on Climate Change, while developing countries will merely be required to submit reports on their progress in meeting their pledges.

But this is only an accord. It has no legal status and was merely ‘recognised’ by the countries at the conference. What is more, the target of limiting temperature rises to 2C does not contain a date by which temperature rises should peak. Also, as countries are not required to submit targets for emissions until February 2010, it is not clear how these targets will be kept low enough to meet the temperature target and there is no identification of penalites that would apply to countries not meeting their pledges.

Not surprisingly, reactions around the world have been mixed. The following podcasts and articles look at these reactions and at the economic mechanisms that will be required to meet the 2C limit

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.

The following video and audio podcasts look at resistance by the US oil and coal industries to measures to curb the consumption of oil and coal. Despite the clearly estabilised link between burning fossil fuels and global warming, many in the two industries reject, or at least question, the evidence. After all, it is in their commerical interests to promote the consumption of fossil fuels!

Elsewhere in the USA, interesting scientific developments are taking place to combat global warming. One measure is the production of ‘green oil’ produced from algae. Growing the algae absorbs carbon from the atmosphere.

In few areas are economic arguments so intertwined with political ones. The podcasts look at some of the issues.

The traditional macroeconomic issues are well-known: unemployment, inflation, economic growth and the balance of payments. However, the environment, and specifically climate change, have become increasingly important objectives for the global economy. Over recent months, many countries have announced new policies and measures to tackle climate change.

The costs of not tackling climate change are well-documented, but what about the costs of actually tackling it? Why is a changing climate receiving such attention and what are the economics behind this problem? The articles below consider this important issue.
