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.

Based on the highest-impact personal actions identified by Wynes & Nicholas (2017) and the IPCC's AR6 report on demand-side mitigation.
