3. Carbon Track & Trace - CTT
• Monitoring, Reporting, Understanding of city-level
greenhouse gas emissions
• Both emission inventories and real-time local
measurements
• Better accounting leads to better prioritization of
mitigation projects
• Part of larger SmartCities approaches

4. Ecosystem
• CTT 2.0 consortium
• NTNU, DTU
• ICLEI-World, ICLEI-Europe, LSCE, South Pole Group,
Virtual City Systems
• Trondheim Municipality, Vejle Municipality, Sør-
Trøndelag Fylkeskommune, T:Lab, NumaScale,
Norwegian Institute for Air Research
• Additional local projects, collaboration with DTU, H2020
proposals, Smart Sustainable Cities initiatives

5. Approach and Activities
•Integration of measured GHG data into city planning and
decision support
•Deployment of LoRa sensor network in Trondheim and Vejle
•Development of an analytics framework of GHC emissions
•Work towards GPC-compliant inventories
• Scaling out, deployment/testing internationally

6. Sensor/networks/external data

8. Conclusion
• Using local data helps to see effects of local actions.
• Good data is a foundation for better decision making.
• To get the most out of the existing open datasets, we
need to invest in ground sensors. This will enable
detailed monitoring of city-level emissions.
• Low-cost sensors can give more detailed local insights.
• Open datasets can reveal patterns in emissions.
• CTT allows for fast feedback loops for decision makers.

13. Development
• Focus on energy and
sustainability since 2007
• Resilience strategy 2016
Shift in focus:
CO2
Energy - kWh
Economy, euro/kWh
Security of supply
Resilience

14. Needs
CO2-inventories =>
Baseline
Activities => doesn’t effect
baseline
Actual level and impact =>
not visible
We need new approches =>
CTT

15. Sensors and cars

16. Hopes
• Data are open - data.vejle.dk
• Data are visible
• Data are useful
• Data are understandable

17. Expectations
• Understanding of current level
• Is there a change over time?
• Does our activities have an
impact?
• Can we change plans on basis of
data
• Can knowledge move people?

18. Important
additional
learnings
• LoRaWAN network
• Experience with city network and
IoT – how can we use that in Vejle?
• Gain knowledge inhouse and get
ready for the future
