Become carbon neutral
A way of negating unavoidable carbon emissions is to pay for greenhouse gas (GHG) reductions to be made elsewhere, such as via tree plantings, wind farms and hydroelectricity. This is known as carbon offsetting.
If enough offsets are purchased to balance all emissions remaining after reduction efforts, then the net emissions will be zero. This is known as carbon neutrality.
Offsetting is a market-based mechanism and is typically transacted in metric tonnes of carbon dioxide equivalent (CO2-e). Purchasing one tonne of carbon offset means there will be one less tonne of carbon dioxide (or an equivalent greenhouse gas) in the atmosphere than there otherwise would have been.
Carbon neutrality can encompass an entire organisation's activities or a part, such as its head office, fleet of cars, a product, an event or air travel.
The claim of 'carbon neutrality' can be used when it has been demonstrated that GHG emissions have firstly been properly calculated and accounted for and then offset so that net emissions equal zero.
