Increasing atmospheric concentrations of greenhouse gases (GHGs) such as carbon dioxide, methane, and nitrous oxide cause climate change. In the United States, several voluntary and regulatory markets have emerged which allow for purchases of carbon offsets. In many of these markets, agricultural conservation can be a source of offsets. These markets can help incentivize carbon sequestration and GHG mitigation in the agricultural sector while providing farmers compensation for environmental benefits. Below are links to resources, tools, and registries for carbon markets.
