One scientist is reducing his carbon footprint by swapping planes for trains for a full year.
Shaun Hendy, physicist and professor at the University of Auckland, wants to see the science community lead by example.
Mr Hendy said while the science community advises the public to “tighten their belts” with carbon-heavy travel, scientists need to cut back themselves.
Mr Hendy joined Wendyl Nissen on The Long Lunch to discuss his year without plane travel.
Airplane travel has been called out by scientists and media outlets as the least carbon-friendly travel option.
The physicist typically sees around three international trips a year, and said that overseas conferences or research trips are common for many scientists.
