The COMET-Farm™ tool enables farmers and ranchers to estimate carbon sequestration and greenhouse gas emissions related to annual crop production, livestock, and on-farm energy use. This producer-focused tool provides a convenient yet scientifically rigorous way to evaluate the benefits of various conservation practices in reducing greenhouse gas emissions and increasing carbon sequestration. COMET-Farm provides a robust decision support platform, helping facilitate decisions relating to the generation of voluntary carbon offsets, meeting the increasing requirements of sustainable supply chain requirements within the marketplace, and helping farmers/ranchers/forest landowners make informed emissions/sequestration decisions that support climate change solutions.
