Microsoft has created software that allows cities to track their carbon emissions.

Project Two Degrees
works by allowing users input data on emission producing activities such as fuel and electricity consumption, vehicle traffic, waste production, industrial processes and air and sea vessel fuel use. The software then converts the data into tons of CO2 equivalent, taking into consideration the source and type of energy and fuel used.

The tool allows governments to then create an action plan to reduce greenhouse gas emissions. Users are also able to provide access for third-party verification of inventory data accuracy. The action plan section allows cities to set parameters to predict future green house gas emissions and establish reduction goals.

Cities can then plan reduction measures and see how those goals will reduce emissions over time.

This type of software could also be useful to businesses, especially if a cap and trade system came into effect. It would also be useful in eradicating claims of greenwashing.
