תקציר	Carbon footprint analysis quantifies the total greenhouse gas (GHG) emissions—expressed in CO2-equivalent (CO2e)—attributable to an activity, product, organization, or process. Developed from life cycle assessment (LCA) and Intergovernmental Panel on Climate Change (IPCC) methodologies, carbon accounting encompasses direct emissions (operations, combustion) and indirect emissions (supply chain, energy consumption, waste). Carbon footprints inform climate mitigation strategies, corporate sustainability reporting, product labeling, and carbon pricing mechanisms.	Biogas production modeling is a quantitative method to predict methane and carbon dioxide generation from anaerobic digestion of organic residues (wastewater sludge, food waste, agricultural manure, slaughterhouse waste). Developed from microbial kinetics and thermodynamics, these models account for substrate composition, microbial consortia (acetogens, methanogens), process conditions (temperature, pH, retention time), and inhibition factors (ammonia, volatile fatty acids). Biogas modeling supports reactor design, energy recovery planning, and operational optimization.
