Community Impact Modelling Tool (CIMT)

Published21st January 2014

The community impact modelling tool estimates the impact community led activities have on waste, energy and carbon reductions, and the associated financial savings of these reductions for local authorities and consumers. The results will be used to justify funding and support for groups both to Local Authorities and other funders.


The model is designed in MS excel and is used alongside an online data portal which collects and formats data ready for transferral into the model. The model contains multiple activity sheets representing all the activities currently known to be organised by community groups. Each activity is assigned measurable outcomes to enable the model outputs to be calculated. The model uses data collected from community groups about these activities along with data from external sources showing how taking a measure can reduce waste, carbon emissions and a number of other outputs. Community groups participating in the modelling project have access to the data portal where they can generate questionnaires to help them collect the required information and also submit the data after an activity. Within the model this data is combined with information from external sources to estimate the impact of an activity. The results will be presented to community groups, Local Authorities and other funding bodies to highlight the contribution that community action is making towards building a low carbon Britain.


The modelling project is currently managed by a full time member of staff. This role involves developing and maintaining the modelling tool and providing support and guidance to all groups accessing the portal and model. As new groups participate in the project new activities are identified and amendments to existing activities are found. With a staff member these changes can be made to ensure the modelling project remains relevant to all participants. Along with the development of the modelling tool, the project aims to create an extended network of community groups nationwide. This will generate an enhanced knowledge of the low carbon activities occurring across the UK and provide a platform for community groups to share their knowledge and experience. Growing and strengthening the network of community groups nationwide will increase the support available to groups from within the existing network which once developed can be sustained independently of the modelling project. The results of the project can also be used to justify the support available through Local Authorities and other funding bodies.
