Walking and cycling have many benefits and help reduce greenhouse gas emissions, but researchers say we need to think about what people eat to fuel their walking and cycling.
Walking and cycling have many benefits and help reduce greenhouse gas emissions, but researchers say we need to think about what people eat to fuel their walking and cycling.
In a paper published in the international journal, Scientific Reports, the researchers say people who shift from passive modes of transport, such as driving, to active modes, such as walking, will have higher energy needs, which could lead to an increase in food-production related emissions.
The study is understood to be the first international estimate of greenhouse gas emissions associated with the extra food intake required per kilometre travelled by active transport.
Lead researcher Dr Anja Mizdrak from the University of Otago, Wellington, says producing the food required to fuel walking and cycling does come at a cost.
“We have a conundrum – but a solvable one. To maximise the benefit on greenhouse gas emissions achieved by increasing active transport, we need to also address dietary patterns. Emissions associated with active transport will be lower if walking and cycling are powered by low-carbon dietary options.”
