"The European measuring network ICOS is the best way we to find if CO2 action has an effect, and where the emissions go," says climate researcher Siv K. Lauvset, of the Norwegian Research Centre, NORCE.

Lauvset was recently appointed coordinator for ICOS (Integrated Carbon Observation System), a European network for monitoring greenhouse gas emissions. One of the unique selling points of ICOS is the ability to make local and regional carbon maps.
