Anthropogenic – (global warming) caused by human activities.
Back-of-house sorting – when no recycling bins or multi-bin systems are provided for guests/delegates/visitors, and waste has to be separated behind the scenes into different waste streams, such as glass, paper and plastic. This can be done either on-site, or off-site at a material recovery facility (MRF). Compare to separation at source™.

Biodiesel – a diesel fuel substitute produced from renewable sources, such as vegetable oil, animal fat or recycled cooking oil. It is important that it be produced from non-food sources to ensure food security.
Biodiversity – Biological diversity encompasses the variety of all living organisms and communities, including terrestrial, marine and other aquatic ecosystems, and the ecological complexes of which they are part. It is the natural wealth™ of the earth that supplies all our food and other natural resources. This is also called the web of life™, on which we depend.

Carbon contribution – a payment made for the specific purpose of reducing a carbon footprint of a specific activity. This could be either voluntary or compulsory (green tax).
Carbon emissions – carbon dioxide (CO2) is the greenhouse gas most emitted by human activity, and therefore often is the focus of discussions on greenhouse gas emissions. The other greenhouse gases are often referred to in terms of CO2 equivalents™ or carbon emissions.™
Carbon footprint the total impact of a person, group or event relating to the amount of carbon dioxide emitted due to the consumption of fossil fuels. Compare with ecological footprint.
Carbon-neutral event – when net greenhouse gas emissions are zero; thus, all the activities related to an event are measured, so that carbon emissions can be reduced where possible, and all unavoidable emissions that cannot be reduced through behavioural changes can be offset through a reputable carbon offsetting programme.
Carbon offsetting – the process of calculating the greenhouse gas emissions generated by activities such as travelling and use of electricity, and then paying for those emissions through a donation to a project that reduces carbon in the atmosphere by an equivalent amount.
Certified and credible officially recognised, convincing, and supported by known facts.
Climate change the gradual increase in global temperature (warming) due to change in the composition of the earths atmosphere. Humans have contributed to climate change, largely by burning fossil fuels, clearing land, and increased farming, which has exacerbated the greenhouse effect.
Composting – the processing of organic waste in the presence of oxygen, resulting in a soil conditioner that can be used as a valuable source of nutrients for plants.
Dual – or multi-flush toilets toilets that have the option of releasing half a flush or a full flush of water to encourage water conservation.
Ecological footprint – a measure of human demand on the earths ecosystems, so that it is possible to estimate how much of the earth (or how many Planet Earths) it would take to support humanity, if everybody lived a given lifestyle. Compare with carbon footprint.
Eco-procurement – giving preference to the procurement of products and services that do not have a negative impact on the environment.
Ecosystem – a system where organisms live, and in which they interact with each other and their environment.
Event greening – the process of incorporating socially and environmentally responsible decision-making into the organising, implementation and participation of an event.
Event-greening practices the actual application of sustainable living principles relating to event management, such as energy efficiency and waste reduction.
Fair-trade – an internationally recognised approach to trading that aims to ensure that producers in poor countries get a fair deal, including a fair price for goods and services, decent working conditions, and a commitment from buyers to provide reasonable security for the producers.
Food miles – the distance food is transported from its production source until it reaches the consumer.
Forest Stewardship Council (FSC) – a non-profit organisation devoted to encouraging the responsible management of the worlds forests. Consumers wishing to support healthy forests and communities should look and ask for the FSC label when purchasing wood or paper products. Fossil fuels a natural fuel, such as coal or gas, formed in the geological past from the remains of living organisms.
Global warming – the effect of climate change that is currently experienced, mainly due to excess greenhouse gases from burning fossil fuels.
Global Reporting Initiative (GRI) Framework – a comprehensive sustainability reporting framework that is widely used around the world.
Green electricity – also called green power is electricity which is derived from renewable energy sources and which is generated in a sustainable manner.
Green rating system – a system to standardise environmental best practice in the industry.
Greenhouse effect – as greenhouse gases accumulate in the atmosphere it acts like a blanket, so that less heat escapes creating a greenhouse effect for the earth.
Greenhouse gas (GHG) – a gas that contributes to the greenhouse effect (global warming) by absorbing inferred radiation. The main greenhouse gases are carbon dioxide, methane, nitrous oxide, ozone, water vapour and chlorofluorocarbons.
Greywater – waste-water generated from non-industrial activities relating to laundry, dish washing and bathing, and that can be recycled on-site for uses such as landscape irrigation and constructed wetlands.
Landfill site – a scientifically chosen, designed, engineered and managed location for the disposal of waste by burying it (informally referred to as a rubbish dump).
Legacy project – the long-term effect of the event on its stakeholders and on infrastructure, environment, economy or society at local, national, and global levels. The most positive event legacy can be an enhanced infrastructure, environment, economy or society compared to the pre-event situation.
Multi-bin system – waste bins providing more than one option for responsible waste disposal, e.g. separation of glass, paper, plastic or tin; dry waste and wet waste, or recyclables and non-recyclables.
Non-renewable resource – a natural resource that cannot be produced, regrown, regenerated or reused on a scale that can sustain its consumption rate indefinitely, such as fossil fuels. These resources often exist in a fixed amount, or are consumed much faster than nature can recreate them, such as coal, petroleum and natural gas.
Organic food – that is grown or raised without synthetic fertilisers, pesticides or hormones.
Organic or biodegradable waste – that typically originates from plant or animal sources, and can be broken down by other living organisms. When organic waste is processed in anaerobic digestion (without oxygen), it produces methane gas, which is valuable if harnessed, but a dangerous greenhouse gas if not used effectively. See composting™ for aerobic digestion™ (with oxygen).
Pedicab a small, pedal-powered vehicle serving as a taxi in some countries.
Recycled content – when a product is partially made out of recycled material, i.e. a portion of the content of the material has been recycled.
