opportunities to get much more out of nature. The brown alternative of business-as-usual is literally a waste of money. It is also ugly and often nasty, as beauty is translated into lifeless monoculture fields and bleak housing estates. The sounds and sights of nature are diminished, replaced by ever-more noise and vistas of the man-made. The scale of the destruction of nature coming down the track if we do nothing should terrify everyone.
Part two is the practical part. It is all about how to secure the prize, what can be achieved, and why it is sensible economics to do so. Pragmatically, it involves five key areas of the natural environment: the river catchments (chapter 3); the agricultural land (chapter 4); the uplands (chapter 5); the coasts (chapter 6); and towns and cities (chapter 7). For each you are asked to imagine what an enhanced nature might look, sound and feel like. For each a practical framework to achieve the greener outcomes is provided, and why we will be more prosperous as a result is explained. To whet your appetite, and to move from the wonders of the imagination to reality, in every one of these areas a few practical examples of initiatives and projects already under way, and potential new ones, are identified.
It is all about river catchment system operators and ensuring the polluter and not the polluted pays; about a new agricultural policy based on public money for public goods, not perverse subsidies for owning land; protecting and enhancing the uplands for their beauty, health and leisure, and the biodiversity, and again not damaging them through perverse subsidies; opening up the coasts and coastal fringes for their full public potential, and stopping destructive fishing practices, most importantly in Marine Protected Areas; and greening towns and cities with trees, parks and Green Belts to improve air quality, childhood experiences, and health and leisure. What is not to like about this, not just from a conservationist’s perspective, but also for the economic prosperity of Britain?
Part three turns to the money – how to pay for it all. Chapter 8 considers public goods, why they matter, why the market won’t deliver them, and how they should be paid for. Chapter 9 looks at the polluter-pays principle, compensation and net environmental gain, and perverse subsidies. The place to start is with the sheer inefficiencies of current policies. An efficient economy is one that internalises all the costs and benefits of economic activities into prices and decision-making. In an efficient economy pollution is charged: it is inefficient not to charge for pollution, resulting in a lower level of economic prosperity. This is both 101 economics, and rarely followed. Not even carbon has a proper price yet. Making polluters pay is the single most radical and effective policy that could be adopted, for economic prosperity and for the environment. The British countryside would be radically different, and radically less polluted, were this simple economic principle adopted. It would not cost anything to the economy in aggregate, and at the same time it would yield lots of revenue, some of which could go to repairing past damage and enhancing our natural environment.
Instead of demanding more public expenditure, conservationists would be better advised to home in on this fundamental economic principle. Why should it be any more acceptable to pollute than to steal? Both take something from others that they do not pay for. Polluters steal people’s health and they force the polluted to pay for what has been done to them. Expecting more public expenditure is something that might motivate protests and campaigns, but most conservationists know that if they wait for the Treasury to open its coffers they will be disappointed. While money is needed, getting to a more efficient baseline is an urgent necessity, making us all better off.
The converse of making polluters pay is to get rid of perverse subsidies. More than £3 billion is spent annually on subsidising Britain’s farmers, £2 billion of which goes on paying them to own land. This absurd policy has been perverse not only for the natural environment but for the farmers themselves, inflating land prices. It came about as a result of trying to get away from the even more absurd consequences of subsidising the prices of agricultural products, resulting in the infamous European wine lakes and butter mountains, and the intensive sheep grazing that has done so much damage to the uplands. Getting rid of perverse subsidies would save a lot of money. It could be better spent. But even if it were just withdrawn, Britain would be greener.
Next comes the fraught subject of compensation for damage to the environment. While there are conservationists who believe that there should be no damage at all, the reality is that there will be. Faced with a population increasing by around 10 million by mid-century, and with more than 200,000 new houses per year for over a decade, more land will be concreted over. Add in the new roads, railways, and energy generation and networks to service all these extra people and the wider growing economy, and damage is inevitable.
Can this damage be squared with enhancing the natural environment? Only if there is compensation over and above the damage to the natural environment elsewhere. This is the net environmental gain principle: any damage must result in not just offsetting it, but by a positive margin. The positive margin is the precautionary principle in action.
Nowhere is it more important to apply these three principles than to climate change and net zero. But to meet the climate imperatives, and at the same time be mindful of the natural capital dimensions, requires us to integrate all of these into the wider environmental context. Net zero might be an environmental disaster if it means planting the wrong sorts of trees in the wrong places. Chapter 10 shows how the smart use of natural carbon sequestration and the creation of natural capital markets can bring the net zero agenda into this broader creation of a green and prosperous land. Markets help to ensure that polluters do in fact pay, public goods are efficiently provided, and that compensation is paid. Money is currently spent in silos, notably the agricultural subsidies. Winning the prize, and making sure we hang on to it, requires cementing the money into a comprehensive and integrated framework. Chapter 11 sets out how to do this within a Nature Fund. This acts a bit like sovereign wealth funds do for oil- and gas-producing countries. It should include the economic rents from these non-renewable activities like North Sea oil and gas production, mirroring other sovereign wealth funds, but it can also bring together the monies from pollution taxes and charges, from subsidies directed towards public goods and the net gain payments. Crucially it would be for nature, not general public spending.
The net gain principle set alongside the polluter-pays principle together ensure that there is enough money to pay for an enhanced natural environment. Add the money previously spent on perverse subsidies, instead going to environmental public goods, and the numbers stack up. We can have a greener and more prosperous Britain, without extra public expenditure.
A Nature Fund would need to be protected from the host of vested interests and from political opportunism. These interests are not just those opposed to the conservation of nature. They include nature organisations, which are notoriously fragmented and quarrelsome. With a pot of money, the Nature Fund will become a target for each and every interest to look after its own, whether specific species or specific habitats and locations. Its constitution matters, as do the rules of engagement. A Nature Fund should encourage cooperation and coordination for the prize as a whole.
The way to do this is to bring the opportunities together into an agreed practical plan to make it happen – a plan of how to integrate the myriad opportunities into coherent actions, and the necessary institutions to deliver this wonderful opportunity. It is about the full delivery, in spirit and letter, of the 25 Year Environment Plan published in 2018.[7] Some will say that this is too radical, but the real radicalism is in doing nothing, in allowing the business-as-usual to continue. This radically worsens the opportunities of the next generation, who will not only be deprived of swallows and flycatchers but, in the process of the continued destruction of nature, find the basic necessities of their lives increasingly compromised.
The 25 Year Environment Plan needs to integrate the principles behind it into the fabric of the economy and government. These are the two aims of the earlier 2011 White paper, ‘The Natural Choice’:[8] putting the environment at the core of the economy; and leaving the natural environment in a better state for the next generation. Although much may be achieved immediately and a number of reforms will help us along this path, to stand the test
