Resum	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.	Environmental Impact Assessment (EIA) is a systematic, structured process to identify, predict, and evaluate the environmental and social consequences of proposed development projects (infrastructure, extraction, manufacturing) before implementation. Mandated by law in most jurisdictions since the 1970s (NEPA in USA, EU Directive 2011/92/EU), EIA integrates scientific analysis of air quality, water resources, biodiversity, noise, and socioeconomic effects with stakeholder consultation and decision-making frameworks to inform project approval, design modification, or rejection.
