Individual action on climate change is about personal choices that everyone can make to reduce the greenhouse gas emissions of their lifestyles. Such personal choices include people’s travel, their diet, shopping habits, homes, and consumption of goods. Individuals can also get active in local and political advocacy work around climate action. People who wish to reduce their carbon footprint (particularly those in high income countries with high consumption lifestyles), can for example reduce their air travel for holidays, use bicycles instead of cars on a daily basis, eat a plant-based diet, and use consumer products for longer.[1] Avoiding meat and dairy products has been called "the single biggest way" individuals can reduce their environmental impacts.[2]
With regards to family size, excessive consumption may in fact be more to blame for greenhouse gas emissions and climate change than population increase. This is because high consumption lifestyles have a greater environmental impact, with the richest 10% of people emitting about half the total lifestyle emissions.[3][4]
