Paris, France: Astrium will contribute to the development and demonstration of a service capable of measuring citywide emissions of greenhouse gases (methane, carbon monoxide and carbon dioxide) as part of the CarboCountCity contract signed with Climate-KIC, worth €4 million. The first measurements will be taken in Paris over a three-year period. The project is closely linked with the greenhouse gas (GHG) monitoring service under development by Astrium Services.
CarboCountCity is one of the very first projects to measure urban GHG emissions directly. These measurements will be used to create highly accurate emissions maps for city councils and local authorities. These bodies will then be able to publish emissions reports such as those required by European legislation at a national level and, above all, assess the effectiveness of their emission reduction policies. Up to now, cities and local authorities have had access only to statistical assessments of GHG concentrations.
In measuring GHG levels in the Paris region, Astrium Services and its project partners will collate data from a network of sensors on the ground and from aerial campaigns. The measurements will then be assimilated with an atmospheric model to create emissions maps detailing the main sources and carbon sinks, with a resolution of approximately one kilometre.
The first citywide GHG measurement demonstrator was trialled by Astrium Services in London in summer 2012 and resulted in the company successfully creating emission maps, based on data from satellites, aerial measurements and from four ground sensors positioned around the city. Experience gained by Astrium Services in carrying out this trial will be applied to the service in Paris.
Cities are the largest sources of CO2 emissions. By collating the existing data and combining it with data from satellites, new ground sensors and aerial campaigns, CarboCountCity will be able to accurately monitor urban GHG emissions, and this in turn will lead to more effective emission-reduction policies.
