What We Do
Over the past 8 years, SEI has become a leader in the analysis of the environmental pressures associated with consumption patterns. Modelling is a natural componant of our work which has led to the development of software tools which are used across national, regional and local government. Find out more about our recent work in this area in the environmental accounting and tools and models links.
REAP includes a scenario editor which can be used to answer 'what if' questions about changes in household consumption and the resulting environmental consequences. Since its launch in 2006 REAP has been used in every english region, Scotland, Northern Ireland and Wales by government organisations and consultancies. Our approach to policy assessment and building capacity for evidence based decision making is summarised in the policy assessment and REAP workshops links.
Finally, our expertise in GIS (Geographical Information Systems) combined with developments in footprint methodology enable us to carry out spatial analysis at the small area level. Follow this link to find out more.
REAP Petite has been updated and improved.

SEI have just released a policy brief on Scotland's Footprint.
Our study has shown that Scotland's carbon footprint has grown by 11 per cent since 1992.
The figure includes greenhouse gases released overseas during the production of goods later consumed in Scotland and so is the most accurate gauge of the country's emissions to date.
While emissions generated in Scotland fell by 13 percent between 1995 and 2004, when trade is taken account, greenhouse gases rose by 11 per cent over the same period.
The full policy brief can be found on SEI's website.
An article has also be published in the Sunday Herald and can be found here.
The NHS England successfully launched their Carbon Reduction Strategy ‘Saving Carbon, Improving Health' on 27th January 2009. SEI contributed to the evidence base for the strategy, carrying out a consumption-based carbon footprint of the NHS England, who represents 25% of England's public sector emissions. The first part of the project examined historical emissions and identified the drivers behind a rising carbon footprint. This forms the first report published in 2008. The second phase of the project projects future emissions and models a range of policy options and their carbon reduction potential.

Our phase 1 report for the NHS England carbon analysis project is available online.
This report provides a 2004 baseline for the NHS, a time series and a supply chain analysis of the pharmaceutical and medical equipment sectors (the highest impact procurement sectors of the NHS England).
We are in the process of developing a carbon scenario tool to contribute to the NHS England Carbon Strategy and target setting. The deadline for this is January and another report will be issued. We are also looking into repeating the study for the NHS Scotland, Wales and NI.
