This is a request to include Direct Air Capture using Free Air
Crop Carbon Dioxide Enrichment (FACE) in the 2022 Climate Change
Scoping Plan for Carbon Neutrality as a strategy for Natural and
Working Lands, especially for Crop Lands as shown on page 255. This
contributes to success of carbon neutrality with a nature based
solution for capturing carbon dioxide by increasing agriculture
production and water utilization efficiency in the largest water
consume by up to 50% and up to 200%. This means that if the CO2 in
the biosphere of crops in increased by up to 50% (from 400 ppm to
600 ppm CO2) then CO2 is removed directly from the
atmosphere. FACE is a proven science and technology that has
been researched by USDA and USDOE for over 50 years. CDFA recently
awarded a SWEEP grant for an almond orchard to recieve CO2 from a
refinery to increase yields and water utilization efficiency by
40%. This is also a request to add FACE to the GHG Calculator tool
so SWEEP grants applications can gain credit for the approximately
10 Metric Tons per year per acre of CO2 captured from a producing
orchard (C3 trees such as Citrus and Almond) per USDA's Dr. Bruce
Kimball.
