The Swine Farm Carbon Offset Estimator is intended to help swine producers and others interested in agricultural offsets estimate the amount of carbon offsets that could be generated by reducing or avoiding methane production on farms.
The Estimator calculates greenhouse gas emission reductions in tons of carbon dioxide equivalents ("CO2e"), which is a measurement that represents the concentration of all major greenhouse gases on a single scale – in units of carbon dioxide – the dominant greenhouse gas. Because methane is 25 times more potent than carbon dioxide, one ton of methane emissions reduced or avoided is equal to 25 tons of CO2e.
Currently, the Duke Carbon Offsets Initiative is working to find ways to help farmers install innovative swine waste management technologies that will significantly reduce or avoid emissions of methane from North Carolina’s swine farms as well as meet stringent environmental performance standards adopted by the state in 2007 for new and expanded farms. These standards include:
- Elimination of direct discharge, seepage or runoff from the waste system
- Substantial elimination of ammonia emissions from the farm
- Substantial elimination of odors on the farm
- Substantial elimination of disease-transmitting vectors and pathogens
- Substantial elimination of nutrient and heavy metals in soils and groundwater
Several technologies now exist that can fulfill these requirements, as well as produce other valuable byproducts, including energy, compost, and soil amendments. Payments for carbon offsets, electricity production, and other byproducts, plus savings realized by improving the health of the animals, could help to make these systems much more accessible.
