At the G7 conference in Bavaria on 7 and 8 June 2015, it was agreed to phase out the use of fossil fuels by the end of the century. But despite this significant objective, there were no short-term measures put in place to start on the process of achieving this goal. Nevertheless, the agreement contained commitments to further developments in carbon markets, elimination of fossil fuel subsidies, incentives for the development of green energy and support for developing countries in reducing hydrofluorocarbons.
The agreement also sent a strong message to the 21st United Nations International Climate Change conference scheduled to meet in Paris from 30 November to 11 December 2015. The G7 communiqué states that binding rules would be required if the target was to be met.
The agreement should enhance transparency and accountability including through binding rules at its core to track progress towards achieving targets, which should promote increased ambition over time. This should enable all countries to follow a low-carbon and resilient development pathway in line with the global goal to hold the increase in global average temperature below 2°C.
But many environmentalists argue that a more fundamental approach is needed. This requires a change in the way the environment is perceived – by both individuals and politicians. The simple 
selfish model of consumption to maximise consumer surplus and production to maximise profit should be rejected. Instead, the environment should be internalised into decision making.
What is more, there should be an integral ecology which brings together a wide range of disciplines, including economics, in analysing the functioning of societies and economies. Rather than being seen merely as a resource to be exploited, respect and care for the environment should be incorporated into our whole decision-making process, along with protecting societies and cultures, and rejecting economic systems that result in a growing divide between rich and poor.
In his latest encyclical, On care for our common home, Pope Francis considers integral ecology, not just in terms of a multidiciplinary approach to the environment but as an approach that integrates the objectives of social justice and care for the environment into an overarching approach to the functioning of societies and economies. And central to his message is the need to change the way human action is perceived at a personal level. Decision making should be focused on care for others and the environment not on the selfish pursuit of individual gain.
With a change in heart towards other people and the environment, what would be seen as externalities in simple economic models based on rational self-interested behaviour become internal costs or benefits. Care and compassion become the drivers for action, rather than crude self interest.
A key question, of course, is how we get here to there; how society can achieve a mass change of heart. For religious leaders, such as the Pope, the approach centres on spiritual guidance. For the secular, the approach would probably centre on education and the encouragement for people to consider others in their decision making. But, of course, there is still a major role for economic instruments, such as taxes and subsidies, rules and regulations, and public investment.

When an industry produces positive externalities, there is an argument for granting subsidies. To achieve the socially efficient output in an otherwise competitive market, the marginal subsidy should be equal to the marginal externality. This is the main argument for subsidising wind power. It helps in the switch to renewable energy away from fossil fuels. There is also the secondary argument that subsidies help encourage the development of technologies that would be too uncertain to fund at market rates.
If subsidies are to be granted, it is important that they are carefully designed. Not only does their rate need to reflect the size of the positive externalities, but also they should not entail any perverse incentive effects. But this is the claim about subsidies given to wind turbines: that they create an undesirable side effect.
Small-scale operators are encouraged to build small turbines by offering them a higher subsidy per kilowatt generated (through higher ‘feed-in’ tariffs). But according to a report by the Institute for Public Policy Research (IPPR), this is encouraging builders and operators of large turbines to ‘derate’ them. This involves operating them below capacity in order to get the higher tariff. As the IPPR overview states:
The scheme is designed to support small-scale providers, but the practice of under-reporting or ‘derating’ turbines’ generating capacity to earn a higher subsidy is costing the taxpayer dearly and undermining the competitiveness of Britain’s clean energy sector.
The loophole sees developers installing ‘derated’ turbines – that is, turbines which are ‘capped’ so that they generate less energy. Turbines are derated in this way so that developers and investors are able to qualify for the more generous subsidy offered to lower-capacity turbines, generating 100–500kW. 
By installing derated turbines, developers are making larger profits off a feature of the scheme that was designed to support small-scale projects. Currently, the rating of a turbine is declared by the manufacturer and installer, resulting in a lack of external scrutiny of the system.
The subsidies are funded by consumers through higher electricity prices. As much as £400 million could be paid in excess subsidies. The lack of scrutiny means that operators could be receiving as much as £100 000 per year per turbine in excess subsidies.
However, as the articles below make clear, the facts are disputed by the wind industry body, RenewableUK. Nevertheless, the report is likely to stimulate debate and hopefully a closing of the loophole.

Since the Global Financial Crisis, and especially since 2010, there has been a significant decline in the volume of commercial freight carried by aircraft. Whilst regional and national economies have been hit by fiscal problems, credit snarl-ups and twitchy consumer demand, increases in the price of crude oil (until recently) have compounded air freight cost increases, leading to substitution towards the main alternatives.
Whilst some multinational businesses have shifted production back ‘on-shore’, there has been unprecedented growth in sea freight. In the latter case there are, of course, both ‘winners’ and ‘losers’. As the world’s seas and oceans become more and more congested, one of the distinct losers is a large species which shares the water with commercial maritime transport: the whale.
A recent ‘Sharing the Planet’ documentary on BBC Radio 4, highlighted the plight of whales in the world’s open waters. Since the imposition of controls upon the whaling industry, whale numbers had stabilised and even increased. However, the past five years has seen the most significant threat coming from the eerily clinical-sounding ‘ship strike’: that is, unintended incidents of ships hitting and either injuring or killing whales. In particular, the Blue Whale and the Right Whale have been most affected – the Right Whale was almost driven to extinction by ship strikes in the North Atlantic region.
International action is driving a regulatory approach which aims to intervene, for example, to impose speed restrictions in known waters where whales congregate. But this isn’t a universal solution. Even where it is applied, enforcement is tricky and there is industry resistance as already slow shipping freight delivery times are further extended, thus challenging producers under pressure to respond rapidly to changing consumer demand in the world of ecommerce.
But where is the link to the movie Frozen? Well, this year’s top-selling range of toys are tie-ins to Disney’s wintery animated blockbuster. Excess demand for some of the tie-in merchandising has led to 
short supply in toy stores and carefully planned production and shipping plans junked. Panicked creation of extra capacity in off-shore production has had to be complemented by the contracting of air freighting options – the lead times are too long to get last-minute products to distributors and retailers in time. Whilst someone has to bear the increased financial cost, the whale might therefore become – at least temporarily – a beneficiary.
But the message is clear: globalised production and distribution involve a complex web of trade-offs. 
Where negative externalities hit those without a global voice, this adds weight to the continued efforts towards sustainability and the full costing of production and exchange. Whales are a ‘flagship species’ in diverse ecological systems. The planet cannot afford to lose them. And so, whilst your gift purchases this festive season may have been made possible by products having been air-freighted rather than being sent by yet another ship, don't rest on your laurels. Consider this variant on a traditional injunction: whales are for life, and not just for Christmas.

Questions
- Why might UK-based businesses be concerned with the plight of whales in the world’s seas and oceans?
- In what ways might shipping firms – and the manufacturers who contract their services – be regarded as ‘good’ businesses?
- Using the concept of externalities, how would you account for the impacts of global commerce upon whales?
- How could you conduct a scientific evaluation of the trade-offs involved?
- Can damage to one species by the actions of business ever be offset by ‘making good’ through corporate action elsewhere?
GDP figures are often a poor measure of a country’s economic well-being. By focusing on production, they may not capture the contribution of a range of social and environmental factors to people’s living standards, including the various negative and positive externalities from production and consumption themselves. A case in point is internet innovation: an issue considered in the first linked article below by the eminent economist, Joseph Stiglitz.
The effects of innovations that directly lead to an increase in output are relatively easy to measure. Many innovations, however, may allow those with power to consolidate that power, resulting in less competition and a possible decline in welfare. If, for example, companies such as Amazon, invest in online retailing and gain a first-mover advantage, they may be able to use this power to drive out competitors. In other words, innovations may not simply lower the cost of production and hence prices: they may even lead to an increase in prices.
Then there are innovations, such as faster broadband, that result in higher quality. While higher quality in one sphere may lead to higher output elsewhere, in many cases it is just improving the experience of consumers without being reflected in a way that can be easily measured.
Some innovations may be judged as socially harmful. Thus improved gaming functionality and realism may encourage people to spend more time online. The social and health implications of this may be considered as undesirable and resulting in a reduction in well-being. Of course, many gamers would disagree!
The point is that technological innovations often result in a change in tastes. These changes in tastes may involve negative externalities, themselves very hard to quantify. Consequently, 
resulting changes to GDP may be a very poor indicator of changes in social well-being.
The articles below consider some of these issues. The Stiglitz article gives an example of innovation in financial services. Although highly profitable for many working in the sector – at least until the crash of 2008/9 – according to the author, these innovations led to both lower GDP growth and a net contribution to social welfare that was negative.

While much of the UK is struggling to recover from recession, the London economy is growing strongly. This is reflected in strong investment, a growth in jobs and rapidly rising house prices.
There are considerable external economies of scale for businesses locating in London. There is a pool of trained labour and complementary companies providing inputs and services are located in close proximity. Firms create positive externalities to the benefit of other firms in the same industry or allied industries.
London is a magnet for entrepreneurs and highly qualified people. Innovative ideas and business opportunities flow from both business dealings and social interactions. As Boris Johnson says in the podcast, “It’s like a cyclotron on bright people… People who meet each other and spark off each other, and that’s when you get the explosion of innovation.”
Then there is a regional multiplier effect. As the London economy grows, so people move to London, thereby increasing consumption and stimulating further production and further employment. Firms may choose to relocate to London to take advantage of its buoyant economy. There is also an accelerator effect as a booming London encourages increased investment in the capital, further stimulating economic growth.
But the movement of labour and capital to London can dampen recovery in other parts of the economy and create a growing divide between London and other parts of the UK, such as the north of England.
The podcast examines ‘agglomeration‘ in London and how company success breeds success of other companies. It also looks at some of the downsides.
