SCS Global Services （SCS） has evaluated a new methodology for measuring the carbon sequestration（封存） ability of soil under the Verified（验证） Carbon Standard （VCS）, a leading greenhouse gas （GHG） accounting system． The methodology, developed by The Earth Partners, will allow land managers who sequester GHGs in grasslands and farmlands to produce carbon credits for sale in the voluntary market．
Managers of grasslands and farmlands can increase carbon sequestration in soil by practices such as changing grazing（放牧） practices and operating treatments designed to improve the variety and productivity of plant groups． The Earth Partners is presently piloting this methodology with farmers across seven million acres of the Palouse River and Columbia Plateau regions in the Pacific Northwest．
“The VCS program has achieved an important milestone in now combining grassland and rangeland carbon offset（抵消，补偿） projects," said Dr． Robert J． Hrubes, Executive Vice President of SCS． "SCS looks forward to approving and verifying agricultural carbon offset projects that use this very powerful new methodology．"
The VM0021 Soil Carbon Quantification Methodology is based on decades of soil carbon research and testing conducted by top soil scientists． The methodology was developed by The Earth Partners and verified by Environmental Services, Inc． as well as SCS Global Services． It is the first soil carbon methodology to be approved for use under the VCS．
"This widely tested methodology is the first to specially deal with soils in a market," said Steven I． Apfelbaum, Chairman of Applied Ecological Services, Inc． and Director of Science with The Earth Partners． According to Apfelbaum, soils represent the second largest living sink of carbon on the planet．
