Carbocount City

Carbocount City has developed an emissions measurement system with the potential to be replicated in all mega-cities across Europe.

The system is being trialled in two European cities, using sensors and processes to take, model and report accurate measurements – networks of seven stations over Paris and two over Rotterdam were set, and the reports produced will be used as input for COP 21.

The CarboCount project represents a considerable investment in terms of research and development. Climate-KIC has been critical in supporting the long term vision which CarboCount has, providing both the potential contacts and financial assistance necessary to develop this into highly innovative and marketable product.

A ground-breaking innovation

Current data on urban greenhouse gas (GHG) emissions is based on a “bottom-up approach”, namely multiplying the number of emitters by estimated coefficients. This means that the most GHG emission sources cannot be pinpointed nor mapped, and so little can be done to reduce emissions in these areas.

Carbocount City objective is to improve the way in which emissions data is recorded, by providing more detailed information on the sources of GHG emissions and enhance city authorities’ emission reduction plans.

Societal Impact

A huge percentage of the world’s CO₂ emissions can be attributed to large cities. Currently, cities producing particularly large quantities of GHGs are facing trouble to promote their activities in this field notably in international emission reduction schemes, due to a lack of accurate data on the overall quantities of annual CO₂ emissions and their exact source.

Current GHG inventories in place are not based on observational evidence. Because of this, it is difficult to identify the areas where their emission reductions efforts are the most effective.

Carbocount City aims to provide clarity of information about the areas & sources where actions could be taken by a city to effectively reduce CO2 emissions & better promote its efforts.

Key Facts

A first contract was signed with Recife in summer 2014. This contract is for a pilot implementation of Carbocount City service over the city.

Technical collaboration is currently being implemented & should enable Carbocount City consortium to fine-tune its service & better adjust its business plan.

Discussions with other authorities (cities, but also universities over the world) are ongoing.

The innovation was created within Climate KIC innovation programme and involves the following partners: Université de Versailles, SaintQuentin-en-Yvelines (UVSQ), TNO (Netherlands Organisation for Applied Scientific Research), Aria Technology and the Commissariat à l’énergie atomique et aux énergies alternatives (CEA).
