Σύνοψη	Air dispersion modeling is a quantitative method to predict the concentration and deposition of air pollutants (dust, gases, particulates) released from industrial sources, traffic, or combustion. Developed empirically by Pasquill and Gifford in the 1960s and formalized into the Gaussian plume model, these methods predict ground-level concentration downwind of a source using wind speed, stability class, source height, and meteorological data. Air dispersion models are essential tools for regulatory compliance, emission permitting, and exposure assessment.	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.
