What is a tonne of car­bon diox­ide?

Element - - Business -

Dr Gelvin Steven­son of the Cen­ter for Eco­nomic and En­vi­ron­men­tal Part­ner­ship in the US worked out this ex­am­ple to help vi­su­alise the weight and vol­ume of car­bon diox­ide emis­sions: Say you drive 13,000 kilo­me­tres in a large sports util­ity ve­hi­cles each year. The four tonnes of car­bon emit­ted will weigh roughly the same as the car, and the pure gas would take up a vol­ume equiv­a­lent to 140 small saloon cars. Put an­other way, each tonne of pure CO2 would take up roughly the space of a two storey house.

New Zealand’s con­tri­bu­tion to world­wide car­bon diox­ide con­cen­tra­tions in 2010, tak­ing into ac­count the car­bon diox­ide re­moved from the at­mos­phere by ac­tiv­i­ties like forestry, is 72 mil­lion tonnes.
