Introducing the Resources and Energy Analysis Programme (REAP)

The Resources and Energy Analysis Programme (REAP) is a software tool developed by the Stockholm Environment Institute (SEI) that uses an environmentally extended input-output model to track greenhouse gas emissions, air pollutants, and ecological footprints based on consumption rather than just production. By distinguishing between domestic and imported goods across 178 sectors, REAP allows users to create quantifiable scenarios based on the IPAT formula (Population, Affluence, and Technology) to test policy interventions. The tool has been applied to various UK sectors, including the NHS and tourism, and used in regional planning, such as housing scenarios in the Tees Valley. SEI is expanding the tool's application to EU-27 members, Sweden, and the Basque Country.

• The consumption-based accounting approach reveals that UK consumer emissions are higher than producer emissions; for example, in 2004, UK consumer emissions were approximately 730Mt CO2, which was 20 per cent higher than producer emissions.
• REAP utilizes an environmentally extended input-output model that tracks the flow of goods and services between the UK and the 'rest of the world' across 178 individual sectors, calculating the impact per pound (£) spent for 356 product groups and over 50 consumption categories.
• The REAP scenario editor is based on the IPAT equation, allowing users to alter over 200 variables across three determinants: Population (size and number of households), Affluence (per-capita expenditure and consumption baskets), and Technology (energy mix and industrial energy demand).
• SEI has developed a 'family' of models based on REAP's methodology to target specific sectors, including tools for the UK education sector and the National Health Service (NHS). For the NHS, 60 per cent of emissions are linked to the manufacture and transportation of purchased goods and services.
• In a case study of the Tees Valley, a 'Business as Usual' scenario predicted a 1.8 per cent increase in CO2 emissions from household fuel and electricity over 20 years, which equates to a 5.5 per cent increase per person due to projected population decline.
• The Tees Valley workshop demonstrated that combining measures to increase renewable energy, improving energy efficiency in existing homes, and raising energy performance requirements for new homes could reduce the housing carbon footprint by at least 10 per cent over 20 years.
