It is this molecule that shoulders the most social blame for global warming due to its greenhouse effect in the atmosphere. No publisher admin 2009-12-05T15:25:21Z Page http://www.knowyourplanet.com/learning-zone/glossary/c/carbon-dioxide-emission Simply the amount of gaseous carbon dioxide released from a particular source, both anthropogenic (chimney stacks, exhausts and the general burning of fossil fuel) and natural (volcanoes, forest fires and biological). The units of measurements are normally kilograms (kg) of CO2.

No publisher admin 2009-12-05T15:27:00Z Page http://www.knowyourplanet.com/learning-zone/glossary/c/carbon-neutral To be carbon neutral, a process must remove the same amount of carbon from the atmosphere as it releases i.e. an organisation’s carbon footprint must equal zero if they are to be carbon neutral. No publisher admin 2009-12-05T15:27:22Z Page http://www.knowyourplanet.com/learning-zone/glossary/c/carbon-sequestration The removal of carbon from the atmosphere to be put into storage in another part of the carbon cycle. This can be performed directly or indirectly.
