In this standard, the definition of a carbon-neutral footprint is a 'condition in which during a specified period there has been no net increase in the global emission of greenhouse gases to the atmosphere as a result of the greenhouse gas emissions associated with the subject during the same period'.
'Net-zero' and 'carbon neutral' are two terms which are often used interchangeably, although there are differences between them.
Carbon neutrality is defined by an internationally recognised standard - PAS 2060 Specification for the demonstration of carbon neutrality - which sets out requirements for the quantification, reduction and offsetting of greenhouse gas emissions.
