Climate Impacts

Loaded with nutrients and organic matter Loop helps us to fight climate change by sequestering carbon in the soil and offsetting carbon emissions associated with synthetic fertilizer. By using 100% of Loop as a soil amendment over 42,000 tons of CO2 equivalents are offset each year. That’s like taking over 8,000 cars off the road!
