Meeting the world’s energy demand is a major challenge for society over the coming century. To identify the most sustainable energy pathways to meet this demand, analysis of energy systems on which policy is based must move beyond the current primary focus on carbon to include a broad range of ecosystem services on which human well-being depends. Incorporation of a broad set of ecosystem services into the design of energy policy will differentiates between energy technology options to identify policy options that reconcile national and international obligations to address climate change and the loss of biodiversity and ecosystem services. In this paper we consider our current understanding of the implications of energy systems for ecosystem services and identify key elements of an assessment. Analysis must consider the full life cycle of energy systems, the territorial and international footprint, use a consistent ecosystem service framework that incorporates the value of both market and non-market goods, and consider the spatial and temporal dynamics of both the energy and environmental system. While significant methodological challenges exist, the approach we detail can provide the holistic view of energy and ecosystem services interactions required to inform the future of global energy policy.
Our team has produced a report that considers the ways in which industrial energy and material demand reduction can contribute to a low carbon future for the UK.
This report is a synthesis of some of the research conducted by the centre thus far. It highlights key areas of interest and possibilities for further research.

The steel industry is the world’s largest industrial source of CO2 emissions. Recent UK economic policies have led to reduced domestic steel production giving an apparent reduction in national emissions. However, demand for goods made from steel has not reduced. Emissions have thus been transferred not reduced and implementation of UK climate policies may in future expand this ‘carbon leakage.’ This paper explores how future UK demand for goods made from steel might be supplied while satisfying national climate policies, and how this will influence global CO2 emissions. Current flows and stocks of steel are estimated from existing databases. Evidence from other developed economies suggests that per capita stocks are tending towards a saturation level so future demand is forecast from population growth and the expected rate of replacement of a stable stock. The carbon intensities of five different steel-making routes are used to predict the allowed scale of future domestic steel production within the industrial emissions allowances set in four energy pathways defined by the UK Government. The remaining requirement for steel must be sourced offshore and the associated emissions are predicted, to give an estimate of the global emissions arising from final demand in the UK. The results show that current UK climate strategy may have a limited effect in reducing the CO2 emissions of the global steel industry, unless the UK shifts towards producing more of its own steel products with domestic secondary steel-making. This option would also increase the security of UK supply and support an expansion of UK manufacturing.
Researchers in Leeds (Marco Sakai and John Barrett) examined the effectiveness of border carbon adjustments (BCAs), which have figured prominently as policy instruments to address competitiveness concerns in countries subject to a carbon price. The authors estimated the volume of emissions that could be potentially taxed by BCAs, and particularly focus on the effects of trade provisions and country and sectoral coverage. Their findings indicate that trade provisions can significantly reduce the scope and effectiveness of BCAs. The principle of best available technology and exclusion of electricity reduce the tariffs considerably. The authors argue that BCAs are not optimal policy tools to address carbon leakage concerns, and consequently alternative options should be sought.

Researchers (Kate Scott and John Barrett) at Leeds collaborated with researchers at UCL to investigate changes to the UK energy system if emissions embodied in fuels and energy technologies extracted and manufactured overseas to help meet UK final demand for energy are mitigated in the UK’s territorial target. The model outcomes, which favour an increase in nuclear energy due to cost and deployment assumptions in the energy system model, are discussed in the context of technology barriers, and suggest reductions in end-use energy demand could be a more effective way to meet UK climate targets through energy policy.

Material efficiency, reducing the amount of new material inputs per given level of service or output, can improve both the resource efficiency of an economy and reduce demand for energy and GHG emissions intensive materials. It requires a change in the way materials, components and final products are used along the supply chain with associated impacts on employment. Domestic policy support for material efficiency can be hindered by concerns that reducing demand for new materials will impact on employment. A multi-method approach for evaluating the employment impacts of material efficiency strategies across different products and regions is presented. It is applied to two case studies that could reduce demand for new steel in the UK: car clubs and re-using steel sections. Industry interviews supplemented by a literature review reveal how sector labour intensity, product prices and sales volumes might change along the mobility and construction supply chains in the short-term as a consequence of introducing these strategies. A static multi-regional input-output model is used to estimate the immediate direct and indirect supply chain employment impacts of increasing the material efficiency of steel use in the UK. The principal finding of this paper, based on industry expectations of feasible rates of deployment, is that the initial, immediate consequences of these actions would not adversely affect employment prospects in the UK. This is partly because car clubs can stimulate demand for new vehicles and deconstructing rather than demolishing buildings is labour intensive, substituting domestic labour for imported steel. These initial findings should motivate further research on the opportunities for material efficiency.
Many multiregional input–output (MRIO) databases are used to calculate consumption-based accounts. Results feature in climate policy discussion on emissions reduction responsibilities; yet studies show that outcomes produced by each database differ. This paper compares the emissions associated with value chains from Eora, EXIOBASE, GTAP and WIOD. Structural path analysis identifies the largest paths in each database and the differences in common paths are calculated. For the top 100 value chain paths that contain the largest difference, structural path decomposition is used to identify the contribution each part of the value chain makes towards the difference. The results identify and quantify key flows that are the cause of difference in the databases. From these, we can conclude that key MRIO database construction decisions, such as using the residence or territorial principle for emissions allocation and whether energy spends are reallocated based on physical data, are the major causes of differences.
