The Jean Leon winery in Torrelavit (Barcelona) has partnered with the Center for Ecological Research and Forestry Applications (CREAF) to test the potential of vineyard soils to absorb atmospheric CO2 and suppress climate change. The objective of this three-year carbon sequestration study is to determine which mulch allows more carbon to be retained in the soil.

The project will be planned for a half-hectare-sized ecological garden area, with four different plants from the grass and legume families between the vine verticals, and CREAF will carry out the necessary sampling and analysis to determine the soil carbon concentration before and after the annual planting of cover crops, while Château Jean Leon will be responsible for the agricultural tasks of planting and managing the vineyard.
As researcher Jordi Sardans says, the use of vineyard soils is a wonderful tool for reducing atmospheric CO2 concentrations. It is estimated that the carbon currently accumulated in the Earth"s soils is equivalent to three times the carbon accumulated in all of the Earth's vegetation and twice the carbon in the atmosphere.
