Scenario Modelling Tool

The Scenario Modelling Tool can be used to support decision making and policy drivers in pursuit of emission reduction targets.

It will allow you to investigate impacts of different abatement measures, policy scenarios, emissions of ammonia, oxides of nitrogen, particulate matter (PM2.5), Sulphur Dioxide, volatile organic compounds and greenhouse gases. The tool will also enable its users to evaluate the efficacy of emission reduction strategies, tactics and plans. Under a range of defined or user developed scenarios, on outcomes over a variety of spatial scales and user-defined time frames.

The Scenario Modelling Tool (SMT) baseline emissions are based on the UK projections compiled as part of the National Atmospheric Emission Inventory (NAEI). The NAEI projections are compiled in line with the latest EMEP/EEA guidebook. They take, as their starting point, the latest available estimates of historical emissions and extrapolate into the future, taking into account forecasts of energy consumption (by DESNZ), road traffic (from DfT), and other activity data, as well as assumptions about the impact of environmental policies and measures on emissions.
