A Closer Look at RIPE’s Qualifying Practices: Methodology and Sources for No-Till

We continually work to expand the set of RIPE100 qualifying practices. Here we highlight no-till.

No-till provides robust environmental benefits

The practice reduces greenhouse gas emissions in the range of 0.1 to 0.7 metric tons per acre, but even at the higher end of the climate benefit, it is only worth around $14 per acre.

However, the practice also delivers $60 in soil quality benefits, $25 in water quality benefits, and $20 in air quality benefits per acre, reaching a total of $112 per acre.

Ecosystem ServiceDollars per acre per yearCitation
Carbon Sequestration$7The 2018 “Economic Assessment for Ecosystem Service Market Credits From Agriculture on Working Lands,” report to the Ecosystem Services Market Consortium by Agribusiness Consulting indicates that the GHG value of no-till is $7/acre. On Page 15, it says that in 2017, 95,578,000 acres of field crops were already using no-till, and this reduces CO2e by 33,860,000 tonnes. This equals .35 t/acre, which when multiplied by $20/ton is $7/acre. Page 15 also cites 103 million acres of field crop area currently under conventional tillage could be converted to no-till, and this would reduce GHG emissions by another 37.5 million tonnes. This simplifies to .36t/acre, which also multiplies to $7/acre.

Healthy Soil$60Soil nutrients:
Pimentel et. al. “Environmental and Economic Costs of Soil Erosion and Conservation Benefits.” Science. Vol 267, Issue 5201, pages 1117-1123. 1995. Assumes a cost of $3 per ton of soil for nutrients. This was updated to 2020 dollars and used as a multiplier for values on no-till.

Soil conservation:
In “Environmental and Economic Costs of Soil Erosion and Conservation Benefits,” Pimentel et. al (1995) stated that, “In the United States, an estimated 4,000,000,000 tons of soil are lost every year” on cropland. The study estimated the economic cost of specific types of erosion. In “The Value of the Reservoir Services Gained with Soil Conservation,” Hansen and Hellerstein (2007) estimate the costs of erosion, stating that “a one-ton reduction in soil erosion provides benefits ranging from zero to $1.38 (in 2007 dollars).” Values were converted to 2020 dollars and compared to a $20/ton carbon price.
