For the first time, cement degradation through time was considered in terms of CO2 absorption by researchers of the Laboratory for climate and environmental sciences (LSCE, Gif-sur-Yvette France, CEA/ CNRS/ UVSQ). This carbon sink, which  is growing rapidely has to be taken onto account. LSCE researchers have also conducted data analyses resulting in a more precise estimate of the exact role of the atmospheric CO2 regulation by soils and vegetation, with a strong reduction of More »

          Following on the Global Carbon Atlas project ( organized by LSCE, we have developed a new data visualization using global CO2 emissions data from CICERO. With this application you can interactively explore the emissions of five major sources and their distribution over region and country (50 highest, year 2014). China, the US, Europe and India continue to be the world's top emitters in 2014. In the More »
