Carrots are a major vegetable crop in Australia, ranking 5th in value of production. There have been significant genetic improvements in carrots in recent years, predominately the move to F1 hybrids which are much less sensitive to premature bolting at low temperature. At optimal temperatures of 15-18C, yields can be 55 and even 70 t/ha. [...]

Vegetable crops vary widely in their total greenhouse gas emissions as well as emissions by area of production. For example, potato production results in by far the greatest total emissions of CO2-e, being more than three times more than the next largest production category. However, in terms of emissions per hectare of cultivated crop, potatoes [...]

Carbon footprinting classifies emissions into three categories or scopes depending on whether the emissions are emitted directly as part of the activity (Scope 1) or of they are emitted indirectly by using inputs that emit greenhouses gases in their manufacture or distribution (Scope 3). Electricity purchased for the operation has its own category (Scope 2). [...]
