"I require data on the carbon footprint of various fertilizers (synthetic and organic) and animal husbandry practices, including inputs such as feed, manure, and energy consumption, to estimate the total carbon emissions from these activities."
The carbon balance is calculated by carbon emissions (from fuels, materials, inputs, crops, livestock, waste) minus carbon lost in sequestration (by trees, hedgerows, non-cropped areas, soil carbon, plus offsets from recycling waste products or renewable energy).means The carbon balance is calculated by subtracting carbon emissions (from fuels, materials, inputs, crops, livestock, waste) plus the carbon lost in sequestering carbon (from trees, fences, non-cropped areas, soil carbon, as well as waste products or offset by recycling of renewable energy). Because fossil fuel-based fertilizers and most synthetic pesticides are prohibited in organic farming, it has a significantly lower carbon footprint. Soil organic C regulates critical ecosystem services such as nutrient provisioning, water-holding capacity and soil drainage, soil stability, and greenhouse gas emissions that can mitigate or accelerate climate change.The livestock sub-sector contributed to ~7.5% of total economy-wide emissions and ~63% of gross AFOLU emissions in 2018. Between 2005 and 2018, emissions grew at a nominal rate of 0.01% and have been projected (BAU scenario) to increase to 222.67 million tonnes CO2e by 2030.Their analysis found that manure and synthetic fertilisers emit the equivalent of 2.6 gigatonnes of carbon per year – more than global aviation and shipping combined. Carbon emissions from fertilisers urgently need to be reduced; however, this must be balanced against the need for global food security. In addition, producing fertilisers is an energy-intensive process, on its own responsible for almost 1.5% of total global CO2 emissions. Production and use of synthetic fertilizers results in 1.31 Gt CO2e a−1 (95% confidence interval: 1.15–1.56 Gt CO2e a−1). Unlike many other products, only approximately a third of whole life-cycle emissions are released during production
