Project Preparation

CTT 2.0 (Carbon Track and Trace)

Development of an automated system for the monitoring and reporting of greenhouse gas (GHG) emissions

From guesswork to accurate measurements

Municipal GHG emission data repositories are expensive and time-consuming to build, maintain, validate and evaluate. As a result, many cities do not have access to detailed cost/benefit calculations and measurements, making it difficult to understand the true impact of climate mitigation strategies.

The CTT project will deploy and test a real-time, automated GHG emissions sensor system for city-level emissions. CTT will allow local governments to link specific actions to measured reductions, helping attract increased private capital investments in GHG emissions mitigation projects.

Mitigation strategies: linking cause and effect

The CTT project phase 2 will develop, together with the cities of Trondheim and Sør-Trøndelag in Norway, and Vejle in Denmark, an automated GHG emissions inventory software system that can monitor real-time emissions in the building and transport sectors. For the first time, the cities will be able to link actual emissions to specific mitigation actions/investments.

Low-cost GHG emission sensors will collect street- and building-level data, sending the data to servers over LoRaWAN wireless networks, where the information will be logged, cleaned and analysed using big data software. The data is then visualised via 3D GIS and web-based software, feeding back into the municipal planning and decision systems. Finally, the processed data will be outputted to a variety of GHG emission reporting systems such as the GPC, Covenant of Mayors, or IPCC (Intergovernmental Panel on Climate Change).

CTT 2.0 is a partnership between Trondheim Municipality, NTNU Norwegian University of Science and Technology, Danish Technical University, T:Lab, Wireless Trondheim, Numascale, Norwegian Institue for Air Research, LSCE (Laboratoire des Sciences du Climat et de l’Environnment), VCS, and ICLEI (Local Governments for Sustainability).

The project has benefited immensely from LoCal partners’ contacts and knowledge, including insight from LSCE’s world-class GHG emissions experience.CTT 2.0 welcomes the participation of other cities that wish to test our solution.
