Quick Reference

Renewable Energy Systems

Technologies that harness naturally replenishing energy sources such as sunlight, wind, geothermal heat, tidal forces, and biomass to generate electricity or thermal energy with minimal greenhouse gas emissions.

Carbon Capture and Storage (CCS)

A suite of technologies that capture carbon dioxide emissions from large point sources such as power plants and industrial facilities, transport the CO2, and store it in deep geological formations to prevent it from entering the atmosphere.

Bioremediation

The use of living organisms, primarily microorganisms but also plants and fungi, to degrade, transform, or remove pollutants from contaminated soil, water, or air, restoring the environment to a less contaminated state.

Life Cycle Assessment (LCA)

A systematic methodology for evaluating the environmental impacts of a product, process, or service throughout its entire life cycle, from raw material extraction through manufacturing, use, and end-of-life disposal or recycling.

Wastewater Treatment

A multi-stage process that removes physical, chemical, and biological contaminants from sewage and industrial effluent, producing treated water safe for discharge into the environment or for reuse in agriculture and industry.

Phytoremediation

A plant-based remediation technology that uses the natural ability of certain plant species to absorb, accumulate, degrade, or stabilize contaminants such as heavy metals, pesticides, and organic pollutants in soil and water.

Circular Economy

An economic model that seeks to eliminate waste and maximize resource efficiency by designing products and systems so that materials are continuously reused, repaired, remanufactured, or recycled rather than discarded after a single use.

Environmental Monitoring

The systematic collection, analysis, and interpretation of environmental data using sensor networks, remote sensing satellites, drones, and laboratory analysis to track changes in air quality, water quality, biodiversity, and climate variables over time.

Green Building Design

An integrated approach to building construction and operation that minimizes environmental impact through energy-efficient design, sustainable materials, water conservation, indoor air quality management, and site planning that preserves ecosystems.

Energy Storage Technology

Systems that capture energy produced at one time for use at a later time, addressing the intermittency of renewable sources and enabling grid stability. Technologies include lithium-ion batteries, pumped hydro storage, compressed air, and hydrogen fuel cells.

Key Terms at a Glance

Activated Carbon:A form of carbon with high surface area used in filtration systems to adsorb organic compounds, chlorine, and other pollutants from water and air.

Anaerobic Digestion:The breakdown of organic matter by microorganisms in the absence of oxygen, producing biogas and digestate.

Bioaccumulation:The gradual accumulation of pollutants in the tissues of living organisms over time, often through absorption from food, water, or the environment.

Biogas:A mixture of methane and carbon dioxide produced by the anaerobic decomposition of organic matter, usable as a renewable fuel.

Bioremediation:The use of living organisms to break down or neutralize environmental pollutants in soil, water, or air.

Carbon Capture and Storage:Technology that captures CO2 emissions from sources like power plants and stores them underground to prevent atmospheric release.

Carbon Footprint:The total greenhouse gas emissions caused directly and indirectly by an individual, organization, event, or product.

Circular Economy:An economic system designed to eliminate waste by keeping materials in continuous cycles of reuse, repair, and recycling.

Clean Water Act:A 1972 U.S. federal law establishing the structure for regulating discharges of pollutants into waters and setting quality standards for surface waters.

Constructed Wetland:An engineered wetland ecosystem designed to treat wastewater or stormwater using natural biological, physical, and chemical processes.

Desalination:The process of removing dissolved salts and minerals from seawater or brackish water to produce potable freshwater.

Electrostatic Precipitator:A device that removes fine particulate matter from exhaust gases using an induced electrostatic charge.

Environmental Impact Assessment:A systematic evaluation of the potential environmental effects of a proposed project before approval and construction.

Eutrophication:Excessive nutrient enrichment of a water body, typically from nitrogen and phosphorus runoff, causing algal blooms and oxygen depletion.

Green Building:A structure designed and operated to minimize environmental impact through energy efficiency, sustainable materials, and water conservation.
