Global tourism carbon footprint quantified in world first

For the first time, the world's tourism footprint has been quantified across the supply chain—from flights to souvenirs—and revealed as a significant and growing contributor to greenhouse gas (GHG) emissions.

Scientists make renewable plastic from carbon dioxide and plants

Stanford scientists have discovered a novel way to make plastic from carbon dioxide (CO2) and inedible plant material, such as agricultural waste and grasses. Researchers say the new technology could provide a low-carbon ...

Carbon footprint

A carbon footprint is "the total set of GHG (greenhouse gas) emissions caused directly and indirectly by an individual, organization, event or product" (UK Carbon Trust 2008). An individual, nation, or organization's carbon footprint is measured by undertaking a GHG emissions assessment. Once the size of a carbon footprint is known, a strategy can be devised to reduce it.

Carbon offsets, or the mitigation of carbon emissions through the development of alternative projects such as solar or wind energy or reforestation, represent one way of managing a carbon footprint.

The concept and name of the carbon footprint originates from the ecological footprint discussion. The carbon footprint is a subset of the ecological footprint.
