Structure of presentation
• The basics of environmental sustainability:– We must start by getting right the basic conception of how
the human economy relates to the natural environment – we need to understand the environment/resource problem
• Decoupling, resource productivity and eco-innovation: policy implications
• Implications for economic growth

Some perceptions and misperceptions• There is no shortage of fossil or renewable energy
– The issue is access to energy that is useful for human purposes, i.e. refined oil products in forecourts or oil tanks, gas in pipelines, electricity in sockets
– Energy prices reflect availability, i.e. supply/demand (im)balances, not absolute existence
– Fossil fuels existed well before the industrial revolution, but were useless because people did not know how to use them; what changed was the knowledge of how to use them, not the existence of the fuels themselves.
– The same is true of renewable energy• There is no shortage of materials
– The issue is access to materials that are useful for human purposes, some of which are relatively scarce in occurrence
– Once useless materials acquire new uses and values• One of the major sources of economic growth is the turning of non-
resources into resources• The process that accomplishes this is innovation

The challenge of environmental sustainability
• Climate science and the Millennium Ecosystem Assessment make clear that without a radical reform of the human-nature relation – in favour of nature – human civilisation is at grave threat
• Specifically, nine billion humans cannot live current Western lifestyles and maintain a habitable planet: the first thing to go will be climate stability, the whole biosphere may then start to unravel. Issue is saving the human, not the planet.
• Any aspiration for a sustainable economy must start from the recognition of the need for the sustainable use of resources and ecosystems, rooted in basic laws of physical science

Criteria for environmental sustainability (1)
• Non-substitutable, irreversible, immoderate cost (Ciracy-Wantrup); Safe minimum standard (Bishop)
• Maintenance of biodiversity • Renewal of renewable resources • Daly
– Limit the human scale (throughput) to the earth’s carrying capacity.
– Efficiency (not throughput) increasing technological progress
– Renewable resource harvest less than regeneration rate; waste emissions less than assimilative capacities
– Non-renewable resource exploitation rate less than the rate of creation of renewable substitutes.

Criteria for environmental sustainability (2)
• Prevention of destabilisation of global environmental features such as climate patterns or the ozone layer
• Maintenance of biodiversity • Renewal of renewable resources • Maintenance of a minimum life-expectancy of non-renewable resources • Ensuring that emissions into air, soil and water do not exceed their
critical load for ecosystems nor lead to adverse effects on human health • Conservation of landscapes of special human or ecological significance • Avoidance of risk of potentially catastrophic events• Issues of pollution and the depletion of renewables are currently more
pressing than issues of non-renewables depletion• The first priority is to reduce emissions of greenhouse gases to keep
global average warming below 2oC

The imperative of decoupling physical from financial growth
• Decoupling: a decline in the ratio of the amount used of a certain resource, or of the environmental impact, to the value generated or otherwise involved in the resource use or environmental impact. The unit of decoupling is therefore a weight per unit of value.
• Relative decoupling: in a growing economy, the ratio of resource use (e.g. energy consumption) or environmental impact (e.g. carbon emissions) to GDP decreases
• Absolute decoupling: in a growing economy, the resource use or environmental impact falls in absolute terms
• If GDP growth continues, climate stabilisation at levels of CO2 concentration that limit global average temperature increases to 2oC will require a degree of absolute decoupling of GDP from carbon emissions that is outside all previous experience
UCL ENERGY INSTITUTEUCL ENERGY INSTITUTE
The necessary improvements in resource and carbon productivity
• To achieve 450ppmv atmospheric concentration of CO2, assuming ongoing economic and population growth (3.1% p.a. real), need to increase carbon productivity by a factor of 10-15 by 2050, or approx. 6% p.a.
• Compare current increase in carbon productivity of 0% p.a. over 2000-2006, i.e. global carbon emissions rose at 3.1% p.a.; also
• Compare 10-fold improvement in labour productivity in US over 1830-1955, must achieve the same factor increase in carbon peoductivity in 42 years
• A similar increase in resource productivity is required• Focusing only on carbon may increase other kinds of resource use• A systematic focus on ALL resource extraction is required: make
transparent and accountable the physical basis of the economy

An unprecedented policy challenge
The Stern Review Policy Prescription for climate change
•Carbon pricing: carbon taxes; emission trading•Technology policy: low-carbon energy sources; high-efficiency end-use appliances/buildings; incentivisation of a huge investment programme•Remove other barriers and promote behaviour change: take-up of new technologies and high-efficiency end-use options; low-energy (carbon) behaviours (i.e. less driving/flying/meat-eating/lower building temperatures in winter, higher in summer)•The basic insights from the Stern Review need to be applied to the use of other environmental resources (water, materials, biodiversity [space])•In a market economy, pricing is the key to resource efficiency, investment and behaviour change•Policy is required to bring about a step-change in eco-innovation

Determinants of eco-innovation
• Inputs: financial and human resources, R&D expenditure supporting the technological capabilities of a firm;
• Environmental policy framework (e.g. regulatory stringency, different environmental policy instruments such as technology-based standards, emission taxes or liability for environmental damages);
• Existence of environmental management systems, practices and tools;
• Demand pull hypothesis: expected market demand, profit situation in the past;
• Appropriation problem: competition situation (e.g. number of competitors, concentration of the market), innovation cooperation;
• Influence of stakeholders and motivations for environmental innovation (e.g. public authorities, pressure groups such as industry or trade associations);
• Availability of risk capital;
• Availability of highly-skilled labour force.Source: Kemp & Pearson 2008, p.7

Policies for eco-innovation (1)
• Market/incentive-based (also called economic) instruments
• Regulatory instruments, which seek to define legal standards in relation to technologies
• Voluntary/self-regulation (also called negotiated) agreements between governments and producing organisations
• Information/education-based instruments (e.g. eco-labels), which may be mandatory or voluntary.
• Importance of ‘policy packages’
18
UCL ENERGY INSTITUTEUCL ENERGY INSTITUTE
Policies for eco-innovation (2)
• ‘No general statements can be made about the kind of policy instruments that are best suited to support the development and diffusion of environmental technology.’ Oosterhuis (2006, p.vi)
• Issues for policy makers– Asymmetric information– Commercial confidentiality– Necessary stringency of standards or economic instrument– Importance of context, culture and political factors

• Vehicle fuel efficiency / CO2 emissions– European Union (EUU) / USA / Japan (JPN)
• Energy efficiency of ICT equipment– USA / Japan (JPN) / European Union (EUU)
• Solar photovoltaics– Japan (JPN) / Germany (DEU) / United Kingdom (GBR)
• Substitution of hazardous chemical substances– Sweden (SWE) / Denmark (DNK) / USA / Germany (DEU) 20
UCL ENERGY INSTITUTEUCL ENERGY INSTITUTE
Case study conclusions
• Both market-based and command & control instruments effective in inducing innovation– voluntary approaches have not performed well
• Stringency of the policy intervention (or scale of support provided) is a key factor in its impact on innovation– mandatory public procurement– strong market incentives with significant R&D support– stringent regulation
• Combining ‘technology-push’ and ‘market pull’ interventions is particularly effective– e.g. Japan ICT energy efficiency / solar PV
21
UCL ENERGY INSTITUTEUCL ENERGY INSTITUTE
Conclusions on innovation (1)• Technology is embedded in socio-economic context.
Innovation is driver of change• Radical change is likely to be required to meet current
environmental challenges. This implies complex co-evolving socio-economic transitions
• Environmental policy can certainly influence technological change, but most evidence relates to incremental change
• Indicators of technological change are relatively fast growth of eco-industries and eco-patents, and absolute decoupling of environmental impacts.
• Price-based policies can be effective in driving technological change, but this varies according to context and situation. Sometimes other kinds of policy (e.g. regulation) may be more effective
22
UCL ENERGY INSTITUTEUCL ENERGY INSTITUTE
Conclusions on innovation (2)• There is little evidence of influence over the direction,
as opposed to the rate, of innovation. Influencing the direction may be more important for radical technological change
• Stringency and the point of incidence are as or more important as the type of instrument in influencing technological change
• Need for step change in policy ambition and effectiveness
• Implications for economic growth• Political feasibility

The macro-economic costs of increased carbon and resource productivity
• Pessimists:• Alternative energy sources/other resources are more expensive, are
bound to constrain growth• Cheap, concentrated energy and material sources are fundamental to
industrial development
• Optimists (broadly the Stern Review arguments):• ‘Costs’ are really investments, can contribute to GDP growth• Considerable opportunity for zero-cost or net gain investment in resource
conservation and productivity• A number of low-resource technologies are (nearly) available at low
incremental cost over the huge investments in the energy and other systems that need to be made anyway
• ‘Learning curve’ experience suggests that the costs of new technologies will fall dramatically
• Climate change and other resource productivity policies can spur innovation, new industries, exports and growth

The benefits of innovation to increase resource productivity
• Savings to business: £6.4 billion from measures that ‘cost little or nothing’ (DEFRA 2007)
• Innovation: new technology, economic activity, exports
• Increased resource security (reduced vulnerability): food, water, energy, rare materials
• Environmental improvement: reduced GHG emissions, waste to landfill, extraction of virgin materials

Policies for resource productivity (lessons from NISP) (1)
• Importance of prices to drive productivity improvement– Landfill tax in 2013 will drive out landfill
– Carbon price to drive energy from waste, CHP, biogas, recycling
– Green fiscal reform (Green Fiscal Commission) can meet 2020 carbon reduction targets
• Prices not enough: need for regulation, information– Pricing too difficult: land use, planning, biodiversity, Water Framework
Directive, product design/performance (e.g. buildings, vehicles, appliances)
– Prices don’t work: information failure (main NISP innovation)• Culture, habits, institutional structure (attention/job description)• Businesses won’t pay even though very profitable – rationale for public
intervention (Landfill Tax – businesses pay for disposal; NISP – businesses improve resource and economic efficiency; businesses and government better off)
UCL ENERGY INSTITUTEUCL ENERGY INSTITUTE
Policies for resource productivity (lessons from NISP) (2)
• Rising resource prices support technology, knowledge and innovation
• Complementary policy (e.g. through Knowledge Transfer Networks) can magnify resource-price impacts and accelerate innovation– Developing collaborative research– Sophisticated nation-wide information system– Reducing time lag between invention and implementation, accelerating
diffusion– Helping industry identify and overcome current market barriers – Meeting R&D and technology innovation needs of industry– Research found that 75% of all NISP-inspired projects (‘synergies’)
included innovation• 50% involved best available practice • 20% involved new research
• Realistic resource and waste prices are not the whole story, but an essential part of the mix
UCL ENERGY INSTITUTEUCL ENERGY INSTITUTE
Estimating the macro-economic cost of carbon reduction• Models are essential to integrate cost data in a
representation of– The energy system (MARKAL): energy system cost, welfare
cost, GDP cost– The economy : macro-econometric/general equilibrium models– Good models are ‘garbage in – garbage out’; getting the inputs
right• Stern’s conclusion (p.267)
– “Overall, the expected annual cost of achieving emissions reductions, consistent with an emissions trajectory leading to stabilisation at around 500-550 ppm CO2e, is likely to be around 1% GDP by 2050, with a range of +/-3%, reflecting uncertainties over the scale of mitigation required, the pace of technological innovation and the degree of policy flexibility.”

The cost/political feasibility paradox (1)• The technologies for large-scale climate change mitigation and
increased resource productivity in other areas are, or soon will be, available at affordable cost.
• Government funding of R,D&D will need to increase dramatically, but deployment and diffusion can only be driven at scale by markets.
• Developing and deploying the technologies will require huge investments in low-resource technologies right along the innovation chain (research, development, demonstration, diffusion).
• Financing this investment will require a substantial shift from the UK’s consumption-oriented economy of today to an investment economy that builds up low-resource infrastructure and industries.
• [Fundamental accounting identity: GDP = C + I + G + (X-M)]• This shift need not impact negatively on GDP (incomes) and
employment but will require higher savings and lower consumption rates. This may not be politically popular in a consumer society (UK savings rates fell below zero in early 2008).
UCL ENERGY INSTITUTEUCL ENERGY INSTITUTE
The cost/political feasibility paradox (2)• Stimulating the required investment will require high (now) and rising
resource prices over the next half century, to choke off investment in resource-intensive technologies and incentivise low-resource investments.
• These high resource prices will also greatly change lifestyles and consumption patterns. This too may not be politically popular.
Conclusion• It is not technology or cost, that are the constraining factors to increased
resource productivity, but politics – related to people’s attachment to consumption rather than savings/investment, and aspects of high resource-consuming lifestyles.
• Changing this political reality is the necessary condition for the adequate resolution of environmental sustainability problems including climate change, which will alone avoid the potentially enormous, but still very uncertain, costs of adapting to climate and other events and conditions outside all known human experience.
