Unit: kg CO2 eq

Description: Global Warming Potential (GWP) calculated over a 20-year time horizon, encompassing the influence of short-lived climate forcers (SLCFs). This calculation accounts solely for land use emissions. Characterization factors for SLCFs have been sourced from the IPCC method within ecoinvent, and these factors are rooted in the IPCC 2013 report. While SLCFs are not part of the IPCC's 2021 metrics, the Life-cycle Initiative (UNEP/SETAC 2016) recommends their inclusion in sensitivity analyses of models.
