Table of Contents

1. Core Sustainability Concepts

Sustainability rests on foundational principles that balance environmental health, economic prosperity, and social well-being for present and future generations.

Sustainability — Meeting the needs of the present without compromising the ability of future generations to meet their own needs, balancing environmental, economic, and social considerations.
Sustainable development — Development that meets present needs while preserving the environment, natural resources, and social equity for future generations, as defined by the UN Brundtland Commission.
Triple bottom line — A framework evaluating organizational performance across three dimensions: social (people), environmental (planet), and financial (profit), rather than financial results alone.
Carbon neutral — Achieving a net-zero carbon dioxide emissions balance by reducing emissions as much as possible and offsetting remaining emissions through carbon removal or offset projects.
Ecological footprint — A measure of human demand on the Earth's ecosystems, representing the amount of biologically productive land and sea area needed to support a given population's consumption patterns.

These core concepts provide the philosophical and practical framework for understanding sustainability as an integrated approach to human development and environmental stewardship.

2. Circular Economy Terms

The circular economy represents a shift from the traditional linear "take-make-dispose" model to one that keeps resources in use for as long as possible.

Circular economy — An economic system designed to eliminate waste and maximize resource use by keeping products, materials, and resources in circulation through reuse, repair, refurbishment, and recycling.
Cradle to cradle — A design philosophy in which products are conceived from the outset to be fully recyclable or biodegradable, creating continuous cycles of material use with no waste.
Upcycling — The process of transforming waste materials or unwanted products into new items of greater value or quality, extending their useful life and diverting them from landfills.
Life cycle assessment (LCA) — A systematic analysis of the environmental impacts of a product throughout its entire life cycle, from raw material extraction through manufacturing, use, and disposal.
Extended producer responsibility — A policy approach that holds manufacturers accountable for the environmental impact of their products throughout the entire life cycle, including post-consumer disposal.

Circular economy vocabulary describes a transformative approach to production and consumption that could fundamentally reduce waste and resource depletion.

3. Renewable Resources and Energy

Renewable resources can be naturally replenished, forming the basis of sustainable energy systems and resource management.

Renewable energy — Energy derived from sources that are naturally replenished on a human timescale, including solar, wind, hydroelectric, geothermal, and biomass energy.
Solar energy — Energy from the sun captured through photovoltaic cells or solar thermal systems and converted into electricity or heat for residential, commercial, and industrial use.
Wind energy — Electricity generated by converting the kinetic energy of wind into mechanical power using turbines, representing one of the fastest-growing sources of renewable energy.
Biomass — Organic material from plants and animals used as a renewable energy source, including wood, agricultural residues, and dedicated energy crops that can be burned or converted into biofuels.
Green hydrogen — Hydrogen produced using renewable energy to split water molecules through electrolysis, offering a clean fuel alternative for transportation, industry, and energy storage.

Renewable energy vocabulary is essential for understanding the transition from fossil fuels to cleaner energy sources that forms a cornerstone of sustainability efforts worldwide.

4. Waste Reduction Vocabulary

Reducing waste is a fundamental aspect of sustainability. These terms describe the strategies and practices used to minimize the amount of material sent to landfills.

Zero waste — A philosophy and design principle aimed at eliminating all waste sent to landfills, incinerators, or the ocean by rethinking product design, consumption patterns, and resource recovery.
Composting — The natural process of decomposing organic materials such as food scraps and yard waste into nutrient-rich soil amendment, diverting waste from landfills and reducing methane emissions.
Recycling — The process of converting waste materials into new products, reducing the need for raw materials, energy consumption, and landfill space while conserving natural resources.
E-waste — Discarded electronic devices and equipment, including computers, phones, and televisions, which contain hazardous materials requiring specialized recycling and disposal methods.
Single-use plastic — Plastic items designed to be used once and then discarded, such as bags, straws, and packaging, contributing significantly to environmental pollution and waste.

Waste reduction vocabulary empowers individuals and organizations to adopt practices that minimize environmental impact and move toward more sustainable patterns of consumption.

5. Green Building and Design

Green building integrates sustainability into the design, construction, and operation of buildings, reducing their environmental impact while improving occupant health and comfort.

LEED certification — Leadership in Energy and Environmental Design, a globally recognized green building rating system that evaluates buildings on sustainability criteria including energy efficiency, water conservation, and indoor air quality.
Net-zero building — A building that produces as much energy as it consumes over the course of a year, typically through a combination of energy efficiency measures and on-site renewable energy generation.
Passive design — Architectural strategies that use natural energy flows, such as sunlight, ventilation, and thermal mass, to maintain comfortable indoor conditions while minimizing reliance on mechanical heating and cooling.
Green roof — A roof partially or completely covered with vegetation and growing medium, providing insulation, reducing stormwater runoff, mitigating the urban heat island effect, and creating habitat.
Energy audit — A systematic evaluation of a building's energy use that identifies opportunities for improving efficiency, reducing consumption, and lowering costs and environmental impact.

Green building vocabulary connects sustainability to the built environment where most people spend the majority of their time, making abstract concepts tangible and actionable.

6. Sustainable Transportation

Transportation is a major source of greenhouse gas emissions. Sustainable transportation vocabulary describes the alternatives and innovations reducing the environmental impact of getting from place to place.

Electric vehicle (EV) — A vehicle powered by one or more electric motors using energy stored in rechargeable batteries, producing zero direct emissions during operation.
Carbon offset — A reduction in greenhouse gas emissions made to compensate for emissions produced elsewhere, often purchased as credits to balance the carbon footprint of activities like air travel.
Public transit — Shared transportation systems including buses, trains, and subways that reduce per-capita emissions by moving many people with fewer vehicles.
Bike infrastructure — The network of bike lanes, paths, parking facilities, and sharing programs that support cycling as a sustainable, zero-emission transportation option.
Last-mile delivery — The final step of the delivery process from a transportation hub to the destination, increasingly addressed through electric vehicles, cargo bikes, and optimized routing for sustainability.

Transportation vocabulary helps consumers and policymakers understand the options available for reducing the environmental impact of personal and commercial mobility.

7. Sustainable Food Systems

Sustainable food systems address the environmental impact of producing, distributing, and consuming food while ensuring food security and nutrition.

Sustainable Agriculture

Organic farming avoids synthetic pesticides and fertilizers. Regenerative agriculture goes further by actively improving soil health and sequestering carbon. Permaculture designs agricultural systems that mimic natural ecosystems. Agroforestry integrates trees with crops or livestock for multiple benefits. These practices aim to produce food while preserving and enhancing natural resources.

Food Distribution and Consumption

Farm-to-table connects local producers directly with consumers, reducing transportation emissions and supporting local economies. Food miles measure the distance food travels from production to consumption. Food waste reduction addresses the roughly one-third of food produced globally that is lost or wasted. Plant-based diets reduce the environmental footprint associated with animal agriculture, particularly greenhouse gas emissions and land use.
