Emitegevuse

Emitegevuse is an Estonian term used to describe activity related to emitting substances or energy from a source. The concept encompasses both natural and anthropogenic emissions and is used in environmental science, policy, and industry to describe the generation, measurement, reporting, and control of released substances.

The term combines elements meaning to emit and activity, and it is commonly applied to processes that produce air pollutants, greenhouse gases, heat, or radiation. In practice, emitegevuse covers emissions from industrial processes, energy production, transportation, and natural events such as volcanic eruptions.

Measurement and reporting: Emissions are typically expressed by mass per time (for example, kilograms per second or tonnes per year) or by concentration in air. For greenhouse gases, inventories are often reported in CO2 equivalents (CO2e). Monitoring methods include stack tests, continuous emissions monitoring systems, ambient air monitoring, and modelling.

Policy and regulation: Emitegevuse is central to environmental regulation and market mechanisms. National air quality laws, national greenhouse gas inventories, and regional schemes (such as the European Union Emissions Trading System) require measurement, verification, and disclosure of emissions.

Mitigation and management: Reducing emitegevuse involves abatement technologies (scrubbers, selective catalytic reduction, carbon capture and storage), fuel-switching, energy efficiency, and process optimization. Emission inventories support compliance, inform policy decisions, and drive reporting and transparency.
