		<abstract>The aim of this paper is to analyses the carbon sequestration during to different seasons in Brasilia, Distrito Federal. For this analysis we used the images provided by the new sensor Sentinel  2. The images were downloaded using the low quantity of cloud criteria and looking for two different dates corresponding to the drought and rain season. The images were georeferenced using the software ENVI 5.1. For the analysis of carbon sequestration, we used the index CO2Flux, which consists in the combination of the Normalized Differenced Vegetation Index (NDVI) and the Photochemical Reflectance Index. Were applied an arbitrary transect in the results in two different directions. The data of this transect were transferred to a graph. The variations of the season could be seen with the different shades of gray, principally when the vegetation are concentrated near water zones. The graphs showed differences in the two seasons, showing high values of CO2 sequestration during the rainy season, when the water is more available for the vegetation. The new satellite provided an interesting data with high spatial resolution to make the carbon sequestration analysis and potentially other vegetation dynamics analysis.</abstract>
