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.

Many of the major industries in Australia are oligopolies/oligopsonies. Examples include banking, telecoms, supermarkets, insurance and iron ore. The dominant firms in these markets have been accused of exploiting their market power, both in charging high prices to consumers and driving down the prices paid to suppliers. The result, it is claimed, is that they have been making excessive profits.
But things may be changing. With the rise of online trading, barriers to entry in these markets have been falling. Many of the new entrants are established firms in other countries and hence already have economies of scale.
The first article below examines the challenge to established oligopolists in Australia.

In their manifestos, the parties standing for the UK general election on May 7th state their plans for fiscal policy and, more specifically, for reducing public-sector net borrowing and public-sector net debt. The degree of detail in the plans varies, especially with regards to where cuts will be made, but there are nevertheless some very clear differences between the parties.
The Institute for Fiscal Studies has examined the public finance plans of the Conservatives, Labour, Liberal Democrats and SNP and has published a briefing note (see link below) and an accompanying press release. It accuses all four parties’ plans of being short on detail over specific cuts (especially the Conservatives), and over borrowing requirements (especially Labour):
None of these parties has provided anything like full details of their fiscal plans for each year of the coming parliament, leaving the electorate somewhat in the dark as to both the scale and composition of likely spending cuts and tax increases. In our analysis we have used the information provided in each manifesto, plus in some cases some necessary assumptions, to shed light on the four parties’ plans.
But despite the lack of detail, the IFS claims that there are big differences in the parties’ plans. These are illustrated in the following three charts from the IFS Briefing Note.



According to Carl Emmerson, IFS deputy director:
“There are genuinely big differences between the main parties’ fiscal plans. The electorate has a real choice, although it can at best see only the broad outlines of that choice. Conservative plans involve a significantly larger reduction in borrowing and debt than Labour plans. But they are predicated on substantial and almost entirely unspecified spending cuts and tax increases. While Labour has been considerably less clear about its overall fiscal ambitions its stated position appears to be consistent with little in the way of further spending cuts after this year”.
So what would be the implications of the plans of the various parties for fiscal policy and what, in turn, would be the implications for economic growth and investment? The various videos and articles look at the briefing note and at what is missing from the parties’ plans.

A new group of economies, known as MINT, are seen as strong current and future emerging markets. We’ve had the BRICS (Brazil, Russia, India, China and South Africa) and now we have the MINTs (Mexico, Indonesia, Nigeria and Turkey).
In 2014, Nigeria became Africa’s fastest growing nation. A large part of Nigeria’s success has to do with growth in some of its key industries.
Nigerian’s reliance on the oil and gas industry created an attractive economy for further development and it now has high growth in a diverse range of sectors, including mobile phones, champagne, private jets and ‘Nollywood’. Despite the uncertainty and political unrest caused by Boko Haram, Nigeria is attracting a significant amount of Foreign Direct Investment (FDI) in a range of sectors, indicating its growing diversity and attractiveness to some of the world’s largest multinational companies.
Boko Haram has certainly had a dampening effect on Nigeria’s growth, as has the lower oil price, but this may create opportunities for further diversification. Furthermore there are concerns about how the wealth of the nation is concentrated, given that poverty is still prevalent across the country. However, Nigeria is certainly emerging as a success story of Africa and surely the question that will be asked is will other African nations follow suit?
The following article from BBC News considers the Nigerian economy.
Nigeria’s ‘champagne’ economy bucks Boko Haram effect BBC News, Vishala Sri-Pathma (27/3/15)
Questions
- Is a falling oil price necessarily bad for the Nigerian economy?
- Explain why Boko Haram is likely to have a dampening effect on economic growth in Nigeria.
- Do you think other African nations will be able to replicate the success of Nigeria? Which factors may prevent this?
- If the number of millionaires is increasing significantly, but poverty is persisting, does this tell us anything about what is happening to inequality in Nigeria?
- Is is possible to reduce inequality in Nigeria while maintaining economic growth? Might it even be posible for greater equality to be a driver of economic growth?
- The Nigerian currency is weakening. What has caused this and why may this be a cause for concern?
Scottish voters will be crucial in the upcoming election, with the SNP poised to take many of Labour’s seats north of the border. The future of Scotland will depend on which party comes to power and what decisions are made with regards to its finances.
Nicola Sturgeon wants government spending and taxation powers transferred to the Scottish Parliament, but would this mean spending cuts and tax rises for the Scottish people? Ed Miliband, Labour’s leader has been vocal in pointing out what this might mean, with cuts to pensions or raising taxes. However, given that it is Labour that is facing the biggest threat from the SNP, it is perhaps hardly surprising.
However, as the first video below shows, there would be an estimated £7.6bn deficit in Scotland, according to the IFS if spending and taxing was to be transferred here. This is because the tax revenues raised in Scotland are lower per person and spending per person is higher than across the whole of the UK. Oil prices are extremely low at present and hence this is reducing tax revenues. When the oil price does rise, revenues will increase and so if the split in finances was to occur this would reduce that deficit somewhat, but it would still leave a rather large hole in Scotland’s finances. The following videos and articles consider the SNP’s plans.
