ICLEI provides many tailored reporting tools that help local councils complete the greenhouse inventory and then help set targets and monitor activity.
While councils can develop their own spreadsheets and provide information through the reporting registry this will need to be provided in a way that matches the requirements under the Compact of Mayors and using GPC protocols.
A useful software tool is the called Clearpath
ClearPath Global is a no-cost, online GHG inventory tool for local governments worldwide, made available to support the Compact of Mayors. Developed by ICLEI this tool is useful for long term recording and analysis of local emissions for both corporate and community outcomes.
