A-rated homes need the least amount of energy while G-rated need the most. Since 1 January 2009, all homes being sold or rented must have a BER certificate. BER ratings are carried out by BER Assessors registered with the Sustainable Energy Authority of Ireland.
Biodegradable waste: Organic waste, typically coming from plant or animal sources (for example food scraps and paper), which other living organisms can break down.

Carbon dioxide (CO2): A colorless gas that is naturally produced from animals and people in exhaled air and the decay of plants. It is removed from the atmosphere by photosynthesis in plants and by dissolving in water, especially on the surface of oceans. The use of fossil fuels for energy is increasing the concentration of carbon dioxide in the atmosphere, which is believed to contribute to global warming. See also greenhouse gases and photosynthesis.
Carbon emissions: In the context of climate change, carbon dioxide released when substances, especially oil, gas, and coal, are burned by vehicles and planes, by factories and by homes.

Carbon monoxide: A highly poisonous, odorless, tasteless and colorless gas that is formed when carbon material burns without enough oxygen. Carbon monoxide is toxic when inhaled because it combines with your blood and prevents oxygen from getting to your organs. If a person is exposed to carbon monoxide over a period, it can cause illness and even death. Carbon Monoxide has no smell, taste or color. This is why it is sometimes called the “Silent Killer”. The most common causes of carbon monoxide poisoning in the home are house fires, faulty heating appliances such as boilers, blocked chimney or flues, and rooms not properly ventilated. Carbon Monoxide alarms can be used as a backup to provide a warning to householders in the event of a dangerous build up of carbon monoxide.

The payment usually funds projects that generate energy from renewable sources such as wind or flowing water. Individuals can choose whether to buy an offset (for example to compensate for air travel), but governments and large industries are sometimes required to buy them to meet international targets aimed at reducing greenhouse gases.

Greenhouse effect: The warming of the Earth’s atmosphere caused by increasing levels of gases, such as water vapor and carbon dioxide. These gases absorb radiation emitted naturally from the ground, so slowing down the loss of energy from Earth. The greenhouse effect has always existed; without it, Earth would be too cold for plants, animals and people to survive. But because of the increase in greenhouse gas emissions in recent years, the greenhouse effect is a lot stronger, so leading to global warming. See also global warming, greenhouse gases and radiation.
