The study looked at how different assumptions affect the potential for agriculture and forestry to reduce greenhouse gas emissions in the United States. By using a specific model, the researchers found that varying factors can greatly change the results. Depending on the assumptions, the potential for emission reductions could range from a decrease of 55% to an increase of 85%. Higher carbon prices could lead to more significant changes, like planting trees or energy crops instead of traditional crops, while lower prices might result in smaller changes to farming practices.
