U.S. Farmers Earn First Carbon Credits from Rice Production using Winrock’s American Carbon Registry Rice Protocol

“Through a voluntary rice protocol developed by [Winrock International’s American Carbon Registry], rice growers in the Sacramento Valley of California and the Mid-South (Texas, Arkansas, Mississippi and Louisiana) can implement voluntary conservation management practices on their land that reduce methane, a potent greenhouse gas. Methane management practices include dry seeding, early drainage and alternate wetting and drying – these voluntary conservation management practices significantly reduce the amount of methane generated by rice growing and cultivation. In addition to reducing methane emissions, these conservation practices have numerous “co-benefits” such as reduced water pumping costs, reduced fuel usage, reduced water usage and reduced nutrient loading in downstream water bodies because the rice farmers modify their water consumption practices.”

Winrock has long recognized the threat posed by climate change. ACR, founded in 1996 and operated by Winrock, is dedicated to the belief that markets are the most effective tools to tackle climate change. As such, ACR has developed transparent and science-based methodologies to incentivize carbon reductions in agriculture, transportation and other industries. ACR is also a partner in assuring that California’s landmark Cap-and-Trade Program can manage, verify and credit carbon offsets effectively.
