"Soil sequestration" refers to the process of naturally storing or trapping carbon dioxide (a greenhouse gas) in the soil, helping to reduce its levels in the atmosphere and combat climate change. Full definition
If gross soil sequestration were approximately 6 ppm / year, after subtracting current annual carbon emissions of 2.5 ppm / year net sequestration would be 3.5 ppm per year.» (realclimate.org)
Ensuring that carbon soil sequestration methodologies produce the same «carbon negative bottom line» across geographies, climates, and types of land is no doubt difficult, but imperative. (centerforcarbonremoval.org)
