Explain how the Marin Carbon Project began.

The Marin Carbon Project (MCP) achieves carbon sequestration in rangeland and agricultural soils through research and development of scalable, repeatable "carbon farming" techniques. CCI's Agricultural Carbon Program supports the Marin Carbon Project through applied research, policy advocacy, and development of economic incentives for producers and land managers. MCP recently demonstrated that the use of compost as a rangeland soil amendment can significantly increase rates of soil carbon sequestration, directly removing atmospheric carbon. MCP is now building on this work with additional, diverse demonstration sites and the development of a rigorous protocol that will enable land managers in California and beyond to sequester carbon and possibly participate in carbon trading markets.
