My good friend Jon Flowers recently gave a presentation on sustainability in the Chicago area. He produced this list of terms and definitions to clarify some of the buzzwords that are out there. Of course, no list is comprehensive, but it is a great reference guide, with particularly well reasoned definitions.
Organic-
Organic foods are produced according to certain production standards. For crops, it means they were grown without the use of conventional pesticides, artificial fertilizers, human waste, or sewage sludge, and they were processed without ionizing radiation or food additives.
Free Range-
Historically means the raising of farm animals without fences, allowing the animals to graze on the land and maintain a diverse diet. Now is defined by the USDA only for meat poultry as poultry given “access to the outside”. Egg poultry, swine, and cattle do not have any officially recognized criteria for being defined as “free range.”
Native Vegetation-
Plants of a certain geographic habitat that were not transported to that habitat by man. Native plants are adept at surviving without human intervention (watering, shade, fertilizer). Examples include Illinois prairie grasses and Arizona cactuses.
Biodiversity-
A measurement of the variation of life forms within an ecosystem. Ecosystems with a high level of biodiversity are more apt to survive, as extinction of one species does not result in a gap in the food chain/web.
Community-based Economics-
The practice of encouraging consumers to buy locally made products. The goals of buying local are to encourage self sufficiency of a community, reduce transportation of goods and services, rejection of outside influences, promotion of personal investment in the community, and education of consumers.
Fair Trade-
The idea of giving disadvantaged producers in developing countries or smaller operations a fair chance on the world’s market, thereby supporting their sustainable methods of production. Fair trade products are usually identified with the International Fairtrade Certification Mark.
Global Warming -
Global Warming is the rise in the earth’s temperature resulting from an increase in heat-trapping gasesmainly carbon dioxide and methane) in the atmosphere. Fossil fuels used in the production of electricity may contribute to two-thirds of these gases found in the atmosphere.
Green-
Synonymous with sustainable.
Biofuel-
A fuel derived from living plant material that can be burned for energy.
Hybrid Automobile-
A vehicle that runs on a combination of electric power and gasoline or diesel fuel power. The electric power is supplied by a battery that may or may not be charged via a wall socket. Most commercial hybrids use the running fuel engine to recharge the battery and do not recharge from braking.
Flex uel Automobile-
A vehicle that runs on a combination of conventional gasoline and ethanol, from 0% ethanol to 85% ethanol. A flexfuel model is almost identical to gas-only models. Federal fuel efficiency ratings: http://www.fueleconomy.gov/Feg/findacar.htm
Sustainable-
Meets the needs of the present without compromising the ability of future generations to meet their own needs.
Compact Fluorescent Light-
A small fluorescent light that operates by passing a current through mercury vapor, which gives off ultraviolet light that excites a phosphor coating on the inside of the bulb. The phosphor coating gives off light when excited. CFLs last longer and generate more light with less energy than conventional incandescent (current passed through a filament, which lights up with heat) bulbs. The mercury vapor contained in CFLs is toxic, and all CFLs should be disposed of properly.
Rainwater Harvesting-
The capture of rainwater for human use. Rain barrels (55 gallon drums connected to a residential roof drain) and cisterns (large underground storage tanks) are common storage devices used for harvesting.
Peak Oil-
The idea that world oil production has reached its peak or will in the very near future (US oil production peaked in 1970). Falling production will be accentuated by increases in demand from population growth, the industrialization of developing counties, and ever-shrinking new oil discoveries.
Offshore Drilling-
The drilling of oil wells near coast lines. Oil rigs are given an allowance of oil, drilling fluid, and metal cuttings they may discharge into the ocean. The allowance usually accumulates to about 90,000 tons of pollutants discharged into the ocean over the lifetime of one rig.
Clean Coal-
The process of removing carbon dioxide from the emissions of coal fired power plants (and other CO2 generating sites). Carbon capture and sequestration (CCS) is the most common clean coal technology discussed. There are no power plants in the world that currently capture and sequester their carbon dioxide, and the technology has been deemed infeasible until 2020.
Alternative Energy sources-
Usually refers to renewable energy sources that are not fossil fuel based. Examples include wind, hydro, tidal, solar, and geothermal energy.
Green Building-
The practice of constructing buildings that minimize impact to the environment. Practices include: employing high efficiency space conditioning systems and appliances that are commissioned before operation and maintained properly; designing buildings in concert with their environment; selecting sites that minimize automobile transport, land disturbance, and maintenance; employing fixtures, plumbing, and practices that reduce potable water use and sewage generation; ensuring a proper dwelling environment for inhabitants; and encouraging material, site, and resource reuse as much as possible.
Sustainable Development/New Urbanism-
The practice of constructing new places for human activity with goals of preserving natural functions and minimizing resource use. Trends have been to develop: on previously developed land if possible, near public transportation, with extensively planned communities, using mixed use practices, increasing building density, and encouraging walking and biking.
Composting-
The process of subjecting liquid and solid biodegradable waste to natural bacterial processes to remove all harmful bacteria in the waste and break down the complex molecules of the waste, and then using the finished product for a rich organic soil substitute.
LEED-
Leadership in Energy and Environmental Design. A certification issued by the United States Green Building Council (a non profit trade organization) to recognize environmentally friendly development.
Brownfield-
A vacant plot of land that no one wants to buy because of real or perceived pollutant contamination.
Greenfield-
A plot of land that has not been previously disturbed by a soil grading.
Life Cycle-
The term used to evaluate the whole impact of a human development, activity, or trade good from development to decommissioning/destruction. Synonymous with footprint.
Grey Water-
Water that has been used by a human activity but is not contaminated with bacteria or pollutants that could be degraded by bacteria.
