E cards

An online card that does not use paper, thus eliminating the need to post or mail a card which cuts out on the carbon emissions from transporting that card from door to door.


Waste generated from modern appliances including computers, phones and televisions. The metal and plastic components often contain toxic materials and are difficult to separate. The handling of most E-waste is done in informal workshops in the third-world with very little or no workplace health and safety.

Earth Day

For most places it is on April 22! It is a global celebration of what our planet provides and a platform to raise awareness about environmental issues.

Earth Hour

On March 27, from 8:30 to 9:30, turn off your lights for an hour! In 2010, people in 128 countries took part. It is an event organized by WWF to bring attention to climate change.

Eco Art

Art that is in some way environmentally friendly. It may use recycled materials to physically make the art, or may in someway comment on environmental issues or problems.

Eco Assessment

Looking at a home, business or process in terms of the environmental impact that is produced and creation of goals and actions to reduce those impacts.

Eco Chic

Dressing chic and doing it with garments and accessories that are in someway good for the environment. Buying vintage clothes, garments made with sustainable cloth or fair trade items are all eco chic. Although not very fun for your inner shopping diva, perhaps being most ecochic means not buying new when you don't really need it.

Eco Friendly

Hopefully this indicates the product, service or process is somehow better than alternatives in terms of environmental impacts. However beware of Greenwashing!

Eco Tourism

A spectrum of nature‐based activities that foster visitor appreciation and understanding of natural and cultural heritage, and are managed to be ecologically, economically and socially sustainable.


A fiber made from recycled bottles. Can be used to make fabric with differing textures and properties. Used to make things such as polar fleece coats, carpets and automotive upholstery.


An organization started in France that certifies organic products.


The study of living things and how they interact with each other and the physical environment.


The financial interactions of society and how values of different goods and services interact.


The system where animals, plants and other organisms (such as fungus) interact for energy. The ecosystem includes plants that produce energy from the sun, the animals that eat the plants, animals eating each other and the decomposition of dead organisms.

Ecosystem service

The services that ecosystems provide to people at no cost. These include pollination of crops, clean air, clean water, food provision, replenishishment of fish stocks, tourism and leisure places and flood prevention.

The rate at which work and inputs results in outputs. In general the more efficient something is, the less energy is wasted. More efficient products are usually more environmentally friendly.

Electric Vehicle

A vehicle that uses an electric motor for power. They reduce roadside pollution as there is no exhaust with harmful chemicals coming out the tailpipes. If the electricity the vehicles are charged on is generated by a fossil-fueled power plant (such as coal), then they still contribute to global warming. However most newer electric vehicles still produce less carbon dioxide than their petrol-fueled counterparts.


What comes out the end of the pipe or smokestack. The gas that is the result of the burning of fossil fuels such as coal or petrol. It often contains small particulate matter and chemicals that are hazardous to human health. It also contains carbon dioxide, which is the major greenhouse gas heating up the earth.

Emissions Inventory

Counting and adding up all those emissions and trying to figure out just how much we are putting into our atmosphere and breathing in everyday.

Emissions Standard

A standard to attempt to limit the amount of certain gases that a nation, area, industry, machines or vehicle can emit.

End of pipe solution

Dealing with the environmental emissions of a process only as waste generated. This approach limits what can be done as it does not take into account all the other parts of the waste stream such as reducing the amount of inputs, improving the process to make it more efficient or trying to reuse the waste. So when thinking of how to reduce, reuse and recycle, apply it to all steps in a process and avoid only end of pipe solutions.

Endangered Species

An animal or plant that is at risk of becoming extinct in all or most of its natural range. Endangered species are protected by international treaties. Many endangered species are animals that need large areas of undisturbed habitat for survival.

Endemic Species

A species that is only found in one place. Such a species may be more at risk than others as having only one population base, meaning that once that population is gone, the whole species is gone.


What makes things move and heat. It could be energy from the food we eat and the way we live. It could also be electricity or energy from fossil fuels in an engine. Energy that is generated from fossil fuels has a big impact on our climate. Energy used to produce the food we eat does too.

Energy Audit

A process of checking how a building, process or organization uses energy with suggestions for ways to reduce energy consumption and increase efficiency.

Energy Efficient

How much a process or appliance uses energy in relation to output in relation to other industry standards. The more efficient it is, the better it is for the environment!

Energy Performance Rating

A rating relating to how energy is used through that product. There are numerous different rating schemes in different countries on products ranging from glass for windows, appliances, insulation, and even the whole building.

Energy Star

A specific Energy Performance Rating scheme from home appliances, lighting and computers. In general, the more stars the more efficient and the better for the environment. So be a star yourself and next time you buy, seek out the energy stars!


What surrounds us! Environment can be thought about on many scales-from your home or office environment to your city or area environment to the global environment. Generally when you hear that something is good for the environment, it is talking about the natural environment and that includes all the living things in it.

Environmental Crime

An act that contravenes some environmental law such as illegal fishing, dumping of waste, or release of dangerous chemicals in water run off, when there are laws against it.

Environmental Education

Putting the ideas, process, problems and history of the environmental issues into education. It is not only limited to children and can be as immense as university study or as simple as signs giving environmental tips or information.

Environmental Impact Assessment

A report that results from a process of looking at how a development or action in the future will impact the environment. It aims to assess risks and suggest ways to eliminate, avoid, and minimize those risks. It is sometimes mandatory to do an Environmental Impact Assessment before planning approval is granted.

Environmental Management System (EMS)

A system for a business or organization that lays out the way on how their operations impact the environment, in a planned manner. The system should aim for continual improvement.

Environmental Philosophy

The philosophy behind the movement to be "environmentally friendly". Philosophies on motivations for the environmental movement are wide-ranging and very complex, with a vareity of logics. Also see Stewardship and Gaia Theory

Environmental Regulation

The laws and regulations of an area or country that involve environmental impacts of actions.

Environmental Research

The science that fuels what we know about the environment and the impact humans are having on it. Like any science, it is a huge area of study and can seem overwhelming to get your head around, but is essential to figuring out what state our environment is in, how we are impacting it, and the possible scenarios for the future of the environment and ourselves.

Environmental Science

The science of studying areas of environmental problems and issues. It includes both physical and biological sciences such as physics, chemistry, geography, biology and soil science.


A social, political and ethical movement which is concerned with protecting the environment.


The wearing down of, or grinding away of some thing or materials over time, by wind, water, other substances or chemicals. Erosion is a natural process, but when human activities increase the rate of erosion, it can make things unsustainable. For example soil may take hundreds of years to build up its content and nutrients and if washed away quickly in the space of a few years, the soil would be unsustainable.


Pure alcohol that is derived from plant material such as sugar cane or corn. It can be used in a mix with gasoline to produce fuel that can be used by vehicles that normally use exclusively petrol. It is also the stuff in many alcoholic drinks!

EU Eco Label

A European-wide labeling scheme that certifies that a product or service is in someway more environmentally friendly than others in the same field.

Evaporative Cooling

A cooling system that uses the evaporation of water to cool. It is especially effective in climates that are hot and dry. These cooling systems can be on hugely different scales from cooling systems in electric power plants to a household fan with water mist.


The elimination of any living examples of a species on earth. Although extinctions have been happening for hundreds of thousands of years, today's rates of extinction are much higher than what scientists have seen naturally occurring over the last tens of thousands of years.
