environmentalimpact

Environmental impact refers to the effect of human activities or natural processes on the environment, including changes to air, water, soil, ecosystems, and human health. Impacts can be direct, such as pollution and habitat destruction, or indirect, such as climate change driven by greenhouse gas emissions. Impacts are commonly described across categories including climate change, air and water quality, land use and soils, biodiversity, waste generation, and resource depletion.

Assessment methods include environmental impact assessment (EIA), which evaluates potential effects before a project proceeds; life cycle assessment (LCA), which accounts for environmental effects across the production and consumption chain; and various indicators such as carbon footprint, water footprint, and ecological footprint. These tools support decision-making, monitoring, and reporting.

Drivers of environmental impact include energy production, transportation, industry, agriculture, and urban development. Activities such as deforestation, mining, and intensive farming can alter ecosystems and increase pollution and resource demand.

Mitigation and policy measures include cleaner energy, energy efficiency, pollution control, sustainable transport, waste reduction, circular economy practices, and land restoration. International and national policies, environmental impact assessments, standards, and reporting frameworks guide mitigation.

Limitations and scope include quantifying impact being complex due to data gaps, attribution challenges, regional variability, and time lags. Impacts are interdependent and cumulative, requiring integrated approaches. The concept remains central to sustainable development by balancing ecological integrity with social and economic needs.
