The second largest economy in the world, with a record expansion to its current economic status: China. With a phenomenal population, massive migration to the cities and incredible infrastructure development, China has fast become a key economic player, with environmental and pollution problems to match.

The price of China’s economic development may be too high for some people. Increases in incomes, growth and employment may be good news, but is the cost too high? Do economic growth and progress mean poor health and if so, is this a price worth paying

Another big topic within China is the impact on inequality. With growth accelerating in urban areas, population movement from the rural to the urban has been a common feature across China, but this has also created greater inequality. This population movement has separated families and played a role in creating barriers of access to health and education.

The following article from the BBC considers a range of indicators within China and you may also want to review some earlier blog postings on the Sloman News Site which analyse the Chinese economy.

Questions

  1. What are the key drivers of China’s development?
  2. What are the costs and benefits of rural-urban migration?
  3. To what extent do you think there may be a trade-off between quality and quantity when it comes to infrastructure projects? Or is Chinese labour simply more efficient relative to countries such as the UK?
  4. How should we measure economic development? If access to education and health care is limited in the more rural areas, but widely available in the larger cities, does this suggest a country that is developing?
  5. What are the main externalities that China must tackle? Are they domestic issues or global ones? What about the solutions?
  6. If a key driver of Chinese growth and development is government investment in infrastructure projects, is this true and sustainable growth or do you think it might slowly disappear if the government doesn’t continue to invest?
  7. Do you think the relative success of China can be replicated in other emerging nations and in particular in nations within Africa?

The Governor of California, Jerry Brown, has issued an executive order to cut greenhouse gas emissions 40% from 1990 levels by 2030 (a 44% cut on 2012 levels). This matches the target set by the EU. It is tougher than that of the US administration, which has set a target of reducing emissions in the range of 26 to 28 percent below 2005 levels by 2025.

The former Governor of California, Arnold Schwarzenegger, had previously set a target of reducing emissions 80% below 1990 levels by 2050. Brown’s new target can be seen as an interim step toward meeting that longer-term goal.

There are several means by which it is planned to meet the Californian targets. These include:

a focus on zero- and near-zero technologies for moving freight, continued investment in renewables including solar roofs and distributed generation, greater use of low-carbon fuels including electricity and hydrogen, stronger efforts to reduce emissions of short-lived climate pollutants (methane, black carbon and fluorinated gases), and further efforts to create liveable, walkable communities and expansion of mass transit and other alternatives to travelling by car.

Some of these will be achieved through legislation, after consultations with various stakeholders. But a crucial element in driving down emissions is the California’s carbon trading scheme. This is a cap-and-trade system, similar to the EU’s Emissions Trading Scheme.

The cap-and-trade rules came into effect on January 1, 2013 and apply to large electric power plants and large industrial plants. In 2015, they will extend to fuel distributors (including distributors of heating and transportation fuels). At that stage, the program will encompass around 360 businesses throughout California and nearly 85 percent of the state’s total greenhouse gas emissions.

Under a cap-and-trade system, companies must hold enough emission allowances to cover their emissions, and are free to buy and sell allowances on the open market. California held its first auction of greenhouse gas allowances on November 14, 2012. This marked the beginning of the first greenhouse gas cap-and-trade program in the United States since the group of nine Northeastern states in the Regional Greenhouse Gas Initiative (RGGI), a greenhouse gas cap-and-trade program for power plants, held its first auction in 2008.

Since January 2014, the Californian cap-and-trade scheme has been linked to that of Quebec in Canada and discussions are under way to link it with Ontario too. Also California is working with other west-coast states/provinces, Oregon, Washington and British Columbia, to develop a co-ordinated approach to greenhouse gas reductions

To achieve sufficient reductions in emissions, it is not enough merely to have a cap-and-trade system which, through trading, encourages an efficient reduction in emissions. It is important to set the cap tight enough to achieve the targeted reductions and to ensure that the cap is enforced.

In California, emissions allowances are distributed by a mix of free allocation and quarterly auctions. Free allocations account for around 90% of the allocations, but this percentage will decrease over time. The total allowances will decline (i.e. the cap will be tightened) by 3% per year from 2015 to 2020.

At present the system applies to electric power plants, industrial plants and fuel distributors that emit, or are responsible for emissions of, 25,000 metric tons of carbon dioxide equivalent (CO2e) per year or more. The greenhouse gases covered are the six covered by the Kyoto Protocol ((CO2, CH4, N2O, HFCs, PFCs, SF6), plus NF3 and other fluoridated greenhouse gases.

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)

Questions

  1. What negative externalities are involved with the Goan iron ore industry? Are there any positive externalities?
  2. What difficulties are there in measuring the negative externalities?
  3. How would you set about doing a cost–benefit analysis of (a) expanding the Goan iron ore industry; (b) shutting it?
  4. Explain the following: “The net present value of the opportunity cost for 25 years at 12% social discount rate of giving it up is greater than its environmental cost by Rs 14,449 crore, the report states.” (A crore is 10 million and Rs is the symbol for an Indian Rupee, where £1 = approximately 78 rupees.)
  5. What difficulties are there in attempting to take distribution into account when doing a cost–benefit analysis?

Market failure occurs when the free market fails to deliver an efficient allocation of resources. Pollution by cars is a prime example of a negative externality or an external cost. We pay road tax and face high tax rates on petrol, but another form of government intervention is due to come into effect. From the 1st January 2011, nine models of electric car will be eligible for grants of up to £5000 (although only three models will be immediately available). By subsidising certain electric cars, the government is aiming to give people an incentive to switch to these so-called more environmentally friendly cars, as they will now be cheaper.

There are concerns, however, that generating the electricity to charge these cars still emits carbon dioxide. The Transport Secretary, Philip Hammond, said:

There’s no point in switching the car fleet to running on electricity if the electricity emits vast amounts of carbon dioxide.

So is the electric car the car of the future?

Questions

  1. What is the purpose of a subsidy? Using a diagram explain how it will work and what the impact should be.
  2. Why is pollution an example of a market failure? Illustrate this on a diagram.
  3. Why could electric cars also be an example of a market failure? Illustrate this on a diagram.
  4. How will the subsidy aim to encourage more firms to produce electric cars and also more consumers to buy them?
  5. Is there an argument for increased investment in technology to produce electric cars more cheaply and more effectively?
  6. Why is there such a high demand for car usage?

Governments and businesses across the world have been trying to become more environmentally friendly, as everyone becomes more concerned with climate change and emissions. In the UK, incentives had been put in place to encourage large-scale organisations to reduce their consumption of gas and electricity. The Carbon Reduction Commitment Scheme began in April 2010, with companies and public-sector orgainisations required to record their energy consumption. Then in April 2011 it was planned that those consuming over 6000 MWh of electricity per year (about £500,000 worth) would be required to purchase ‘allowances’ of £12 for each tonne of carbon dioxide that is emitted by their use of fuel: electricity, gas, coal and other fuels. This would require the organisations working out their ‘carbon footprint’, using guidance from the Department of Energy and Climate Change. In the case of coal and gas, the emissions would be largely from burning the fuel. In the case of electricity it would be largely from generating it.

The government had intended to use the revenue received from the sale of allowances to pay subsidies to those firms which were the most successful in cutting their emissions.

By raising money from the largest emitters via a levy and giving it back as a ‘refund’ to those who cut their usage the most, the government would not have been able to raise any revenue, but it did tackle the core of the problem – reducing emissions. However, following the Spending Review, this scheme will now actually generate revenue for the government. Paragraph 2.108 on page 62 of the Spending Review states the following:

The CRC Energy Efficiency scheme will be simplified to reduce the burden on businesses,
with the first allowance sales for 2011-12 emissions now taking place in 2012 rather than 2011. Revenues from allowance sales totalling £1 billion a year by 2014-15 will be used to support the public finances, including spending on the environment, rather than recycled to participants. Further decisions on allowance sales are a matter for the Budget process.

Over 5000 firms and other organisations will now find that their hard work in cutting usage and being more environmentally friendly will give them much less reward, as the revenue raised from the levy will remain in the Treasury. All that firms will now gain from cutting emissions is a reduction their levy bill. The extra £1bn or more raised each year from the scheme will undoubtedly be beneficial for tackling the budget deficit, but it will no longer provide subsidies to firms which reduce their emissions. Furthermore, PriceWaterhouseCooper estimates that it will cost businesses with an average gas and electricity bill of £1 million an extra £76,000 in the first year and this may increase to an additional cost of £114,000 per year by 2015.

It’s hardly surprising that businesses are angry, especially when this withdrawal of subsidy, which some have dubbed a ‘stealth tax’, was not mentioned in the Chancellor’s speech, but was left to the small print of the Spending Review announcement. The following articles look at this highly controversial plan.
