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 their farms.
The Estimator calculates greenhouse gas emission reductions in tons of carbon dioxide equivalent (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 21 times more potent than carbon dioxide, one ton of methane emissions reduced or avoided is equal to 21 tons of CO2e.
The Duke Carbon Offsets Initiative is currently working to find ways to help farmers install innovative swine waste management systems 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 farms that receive funding through the Lagoon Conversion Program as well as 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. These systems can also be made much more accessible through payments for carbon offsets, electricity production, and renewable energy credits, as well as savings realized by improving the health of the animals and new income streams through the conversion of sprayfields to cash crop acreage.
