Select Committee on Environmental Audit Minutes of Evidence


Memorandum submitted by the Environment Agency

SUMMARY

  HM Treasury plays a critical role in delivering the government's environmental and sustainable development objectives.

    —  The Pre-Budget Report (PBR) itself announced little new environmental policy, but HM Treasury's contribution to environmental objectives needs to be assessed across the range of its levers on policy—including the Budget, Spending Reviews and appraisal methodologies (see section 2).

    —  We believe that HMT could be more ambitious in the use of economic instruments and should aggressively pursue "resource efficiency" both as environmental policy and as a part of its wider productivity agenda (section 3).

    —  The Environment Agency strongly supports better regulation and has championed modern "risk-based" regulation. The announcement of a review of "gold-plating" is potentially valuable, but only if it takes a discriminating approach to regulation, which can often be the lowest cost and most effective away to meet objectives. There may be good reasons for domestic regulation to go beyond that negotiated in the European Union or to adopt the broadest interpretation of directives (section 4).

    —  The related announcement of the response to the Barker review on housing has important and as yet unresolved consequences for flood risk, environmental impact and infrastructure demands. It is important that these issues are given substantial emphasis in the review on infrastructure needs announced as part of the PBR; further development of planning guidance in flood risk areas; and the consultation on the Planning Gain Supplement (section 5).

    —  The Committee has asked for views on economic aspects of climate change, particularly in the context of the Stern review. We have great concern about any highly reductionist or mechanistic approach to climate policy. However, it is the proper role of economists to define the utility, weaknesses and limits of techniques such as discounting and monetarisation. The Stern review is likely to consider such issues in some detail. Economics is an important discipline informing the response to climate change, but the principles of sustainable development provide a broader framework in which economic analysis should be embedded (section 6).

1.  INTRODUCTION

  The Environment Agency has a statutory duty to protect and enhance the environment and to make an appropriate contribution towards achieving sustainable development.

  Parliament has also given the Environment Agency a general duty to assist in the delivery of environmental priorities by advising on the development of environmental policy and to promote an understanding of methods for environmental protection and management. This memorandum is provided as part of our efforts to perform these functions.

2.  THE ENVIRONMENTAL ASPECTS OF THE PBR

  The PBR (Chapter 7) contains several new or recent measures. We comment briefly on these below:


PBR measure
Environment Agency comment


Support for alternative sources of energy including further consultation on carbon capture and storage, collaboration with Norway on this technology, and additional funding for Carbon Abatement Technology demonstration;
Carbon Capture and Storage is a potentially important component of the national and global response to climate change. A December 2005 report by the Intergovernmental Panel on Climate Change gave a cautiously optimistic assessment of the potential for the technology. However, it has not yet been proven on a large scale in power generation.


Further measures to improve energy efficiency, through the proposed Green Landlord Scheme and £35 million for the Carbon Trusts, to provide interest free loans for the introduction of energy-saving measures in the business and public sectors;
It is important to address energy use in the public and business sectors. However, the Carbon Trust had proposed a more ambitious approach based on an economic instrument. We hope that the Climate Change Programme Review and Energy Review will develop a more aggressive approach to energy efficiency.


Continuation of the freeze in main fuel duty rates and the duty rates for road fuel gases, due to continued oil market volatility;
We accept the argument that rising market prices can have some of the environmental impact of escalating taxes. However, the important objective is to send long-term signals that motorists and other transport users should expect rising costs reflecting environmental impacts and imperatives to meet challenging climate change objectives. This is important to stimulate long-term changes in the pattern of use and design of vehicles. It is not clear that this signal can be separated from the noise of price volatility at present, and the introduction of congestion pricing should not signal a weakening of environmental objectives.


Commitment to introduce a Renewable Transport Fuel Obligation and enhanced capital allowances for the cleanest biofuels plants, to stimulate the development of alternative fuels;
It is important that the full life-cycle environmental impacts are considered in biofuels policy and different bioenergy sources have markedly different life-cycle impacts. It is important that some quality control accompanies this policy to ensure that it does not make the total environmental impact worse.


In support of the UK's continuing leadership in tackling the international challenge of climate change, progress on taking forward the Gleneagles Plan of Action agreed by the G8 under the UK's Presidency and the Stern Review on the economics of climate change;
We support international action and engagement with major emitters as long as this is additional to and complementary with the Kyoto Protocol process, which these initiatives are.


Progress towards the inclusion of the aviation sector within the EU emissions trading scheme (ETS).
We agree that bringing aviation into the climate change policy arena is both critically important and a challenge. The impact of the inclusion of aviation in the emissions trading system will depend on what allowances are allocated to airlines. If airlines are allocated business-as-usual allowances, it will have little effect. It is the toughness of the cap that determines the environmental outcome, not its inclusion in the ETS per se.



  The measures detailed here and the wider account of environmental policy provided in the report reflect quite cautious policy-making to date. The next 18 months allow for greater ambition in environmental policy-making through:

    —  The Budget 2006 and 2007.

    —  The Comprehensive Spending Review and related processes.

    —  The environmental and infrastructure aspects of the more aggressive post-Barker sustainable communities plan.

    —  The Climate Change Programme Review, Energy Review, and Stern Review of climate change economics.

    —  The forthcoming waste strategy.

    —  The beginning of the implementation of the Water Framework Directive.

    —  Implementation of the government's Sustainable Development Strategy.

3.  THE TREASURY'S ENVIRONMENTAL FISCAL STRATEGY

  The Committee asks "how the Treasury's environmental fiscal strategy could be improved (including the adequacy and effectiveness with which all new budgetary measures are appraised and existing economic instruments are monitored);"

  The government has introduced several important and successful environmental economic instruments. However, we believe this is still an unnecessarily tentative approach. More ambition can be justified and would be consistent with other government economic objectives, such as improving productivity. Opportunities include:

    —  A tougher cap in the second phase of the national allocation plan for the EU ETS, with a better implementation of the polluter-pays principle in the approach to allocation, with auctioning of allocations where appropriate.

    —  Revalorising the climate change levy and making it carbon-based—there is an opportunity to consider this in the Energy Review.

    —  A steeper fuel efficiency gradient for vehicle exercise duty including the introduction of "feebates" if the aim is to sharpen behaviour change incentives whilst maintaining revenue neutrality.

    —  Some form of long-term signal on fuel duty or the cost of motoring, similar in concept to the now-abandoned fuel duty escalator.

    —  Economic instruments that support sustainable consumption and production, notably by incentivising greater activity in the upper strata of the waste hierarchy. At present the economic signals create incentives to divert from landfill to mass burn incineration, but there are few economic signals that incentivise diversion from incineration to recycling, reuse or to reduced waste volumes through more sustainable production and consumption.

    —  Policy packages to address diffuse pollution, which could include taxes or levies on agricultural inputs, with revenues directed to funding reduced pollution in ecologically sensitive areas.

    —  Charges for water abstraction (beyond cost recovery) and compulsory metering in water-stressed areas.

    —  Economic instruments that favour resource-efficient buildings (in terms of water, energy and waste), both encouraging new-build to the highest voluntary standards and incentivising retrofit of the existing stock. There are several options for achieving this.

    —  A new review to identify and phase out residual subsidies to environmentally damaging activities.

  In terms of policy appraisal, there are several approaches that would be helpful:

    —  A proper "invest to save" approach to measures designed to improve resource efficiencies (for example building regulations) that takes full account of life-time social and environmental costs. Paying a higher up-front cost can often create considerable long-term savings in running costs—in financial terms and impacts on the environment. This should be consistent with the "Green Book" policy appraisal methodology, but does not appear to be rigorously applied to policy appraisal in practice.

    —  The use of Strategic Environmental Assessment more widely than strictly required by the relevant EU Directive, for example in assessing major programmes such as the sustainable communities.

    —  A new effort to codify the government's five principles of sustainable development into economic appraisal methodologies.

  Data on the effectiveness of existing economic instruments (including those in use in both the UK and overseas) is important in designing future policy. Knowledge of elasticities, revealed prices and preferences, displacement effects and unintended consequences represent valuable insights and should be monitored carefully. The Environment Agency is working as part of a consortium for the European Environment Agency to develop a methodology to evaluate existing instruments, and to pilot learning from existing practice. The results of this study should be used to inform future policy.

4.  BETTER REGULATION

  The Environment Agency has invested in modernising regulation, and has pioneered risk-based regulation and efficient delivery of legislation whether derived from the EU or nationally.

  The Chancellor has announced a review of "gold plating" in the implementation of EU legislation, to be led by Neil Davidson QC. European law is the source of much environmental regulation in the UK. Given that EU legislation is often the product of compromise rather than optimum design, there is a good case for examining where to place the appropriate emphasis in designing implementation. Whilst the government must ensure that it acts legally in complying with EU legislation, there may be some areas where it can undertake a minimal compliance approach and others where it should take the broadest and deepest interpretation of the obligations. The objective should not be to seek out the most minimal approach to compliance in all cases, but to take a more discriminating interpretation based on UK priorities.

  In some areas, there may be a case to go beyond the requirements of EU legislation and to exercise national discretion to take stronger measures. For example, the UK has adopted a climate change objective of cutting carbon dioxide emissions by 20% by 2010, though the UK's negotiated share of the European Union's Kyoto Protocol target [1] is only a 12.5% cut in all greenhouse gases. In tackling "gold-plating", EU legislation should be seen as a floor determined through negotiated compromise, not a ceiling. In areas where the changes caused by regulation are cost-effective and not trade distorting, there is a good case for the UK going further than the minimum required. This could apply to energy efficiency measures and other resource efficiencies. In the case of the Energy Performance of Buildings directive (2002/91/EC), the UK appears to be under-investing in implementation (perhaps "tin-plating" the directive: the opposite of "gold plating") and some of the environmental and economic benefits of improved energy efficiency will be lost as a result.

  There is also a good case for rehabilitating the tarnished reputation of regulatory approaches. In the right circumstances, regulation can reduce transaction costs, avoid free-riders, overcome market failures like information asymmetries, and provide clear signals about the future public policy framework to investors and R&D functions.

5.  SUSTAINABLE COMMUNITIES

  The PBR announcements also addressed the proposed increase in housing investment. The Chancellor announced reviews of the infrastructure needs associated with the increased house-building objective; a review of the planning system to be led by Kate Barker; and a consultation on a proposal for a Planning Gain Supplement. All will be important in ensuring the programme complies with sustainable development principles.

  New development brings cumulative environmental pressures, for example from the individual and combined impacts of flood risk, water quality, water resources, and waste. We know that the trends and patterns of consumption are already significant for the environment. For example, the domestic sector uses 57% of the water put into supply by the water companies. Water demand per person has increased by 11% between 1992 and 2003. This combined demand from new and existing homes needs to be set against the backdrop that parts of the south east are already abstracting 10% too much water in dry years, and that climate change scenarios are pointing to longer dryer summers.

  The impact of the growth will depend on a range of factors. Depending on where they are located and the standards to which they are built, planned new housing has implications for water resources, water quality, and flood risk, as well as waste management and air quality. As our understanding of climate change develops, it is important that homes are not built in places that will be at risk in future or create excessive long-term liabilities for flood defence or other infrastructure. Of particular concern is the location of housing in areas of flood risk and where water quality and water resources are already stressed. Therefore the Regional Spatial Strategies are the opportunity to balance the investment needs with those of the environment.

  We also look to the Treasury to support better demand management of natural resources. The demand for water created by new and existing homes could partly be met through improved standards of water efficiency. This would reduce the need for costly infrastructure. If high water efficiency standards are applied to all the one million new homes planned for the South East of England this could save 60 million litres a day—enough to supply water for 500,000 people.

  Finally, accelerated development in the South East of England will stretch the capability of some environmental infrastructure to cope. For example, we have estimated that up to 80 sewage treatment works will need to be upgraded in the South East to service the demand from new and existing housing being discussed on the draft SE Plan. Depending on the levels of municipal waste produced, up to 50 waste treatment facilities may also be required to handle waste by 2030.

  These basic services must be properly integrated into any plans for new housing, so investments are anticipated, co-ordinated and made in advance. This makes the infrastructure review critical to ensure that the necessary environmental investment requirements are identified. However, new investment in infrastructure should not replace greater efficiency which, as noted in the case of water use above, can greatly reduce the pressure on the environment.

6.  ECONOMICS OF CLIMATE CHANGE

  The Committee has asked for views on the following: "in the context of the Stern review, the adequacy of conventional economic analysis (including the role of monetarisation, and the use of discounting) as a means of evaluating the long-term environmental impacts of climate change."

  The Environment Agency has responded to the Stern review and can provide this submission if the Committee would find it useful.

  In summary, we are sceptical about overly rigid and mechanistic economic approaches to a climate change or the environment more generally. For example:

    —  Discounting is used to capture time preferences, but a single discount rate does not adequately capture the subtlety of human preferences. Even at a purely technical level, there is good evidence from behavioural economics that time preferences change depending on the time horizon considered (generally lowering further into the future) and so require the use of "hyperbolic discounting" techniques. These variations in assumed time preferences over the periods relevant to climate change can make a significant difference to any appraisal, but are not always applied in climate change economics.

    —  There are important questions about the validity of applying discounting over long periods such as those applicable to aspects of climate policy. When applying discounting beyond the personal horizon of the person or society making the appraisal, there is the clear danger that today's generation will not give adequate weight to the preferences of the future generations—perhaps for resources that may be irretrievably lost or irreversible environmental changes.

    —  "Monetarisation" allows for environmental services and resources to be included in appraisal techniques such as cost-benefit analysis. As such, it can be a useful analytical and investigative tool. However, great care is needed in use of such methods to make decisions. Valuation methodologies may end up comparing the incomparable when environmental services cannot be substituted for traded market goods or services.

    —  The use of monetary valuations in environmental decision-making also risks accentuating environmental inequalities, as poorer people often have lower revealed or stated preferences for environmental amenity. In some applications of economic appraisal, lower "value of statistical life" estimates have been used for assessing climate change impacts on developing countries. Whilst there is an "efficient" economic rationale for this, it underlines the importance of maintaining distributional objectives in policy-making.

    —  Much of the modelling in climate change economics has ignored uncertainties (or caveats them in the fine print) or makes mechanistic assumptions about the response of the climate to the rise in greenhouse gas concentrations. The problem facing society is of making policy decisions under conditions of very considerable uncertainty, where there are rising probabilities of extreme events or non-linear and fundamental system changes. The principles of sustainable development recognise "environmental limits", which are thresholds beyond which the consequences are unacceptable, and the science-based and precautionary approach. The Environment Agency believes that the principles of sustainable development should provide a context in which economic techniques can be applied more narrowly, for example in defining the most cost-effective mix of mitigation approaches or the optimum adaptation investment.

  It would, however, be wrong to regard economics as of little value in climate change policy. There is a rich literature on environmental economics exploring the usefulness and limits of these techniques, and many economists are well aware of the problems of crude approaches to discounting and monetarisation. We expect that the Stern review will provide a valuable synthesis of the state of knowledge in this area and contribute usefully to the development of climate change policy in the UK and internationally.
