What can one person do?

  • Fly less
    One long-haul return flight can outweigh a year of other savings. Swap one flight for a train trip or a call.
  • Eat more plants
    Shifting towards a plant-rich diet is one of the largest steady cuts a person can make, and it starts with single meals.
  • Travel without a car where you can
    Walking, cycling and public transport beat an electric car; an electric car beats petrol.
  • Use your voice
    Personal footprints matter, but system change matters more. Vote, ask your employer and bank what they are doing, and talk about it.
