Individual action on climate change
Résumé
Individual action on climate change can include personal choices in many areas, such as diet, travel, household energy use, consumption of goods and services, and family size. Individuals can also engage in local and political advocacy around issues of climate change. People who wish to reduce their carbon footprint (particularly those in high income countries with high consumption lifestyles), can take "high-impact" actions, such as avoiding frequent flying and petrol fuelled cars, eating mainly a plant-based diet, having fewer children, using clothes and electrical products for longer, and electrifying homes. Avoiding meat and dairy foods has been called "the single biggest way" an individual can reduce their environmental impact. Excessive consumption is more to blame for climate change than population increase. High consumption lifestyles have a greater environmental impact, with the richest 10% of people emitting about half the total lifestyle emissions.
Some commentators have argued that individual actions as consumers and "greening personal lives" are insignificant in comparison to collective action. Others say that individual action leads to collective action, and emphasize that "research on social behavior suggests lifestyle change can build momentum for systemic change." According to respondents to a 2022 survey, climate change is the second most pressing issue confronting Europeans. Over three-quarters of respondents (72%) believe that their individual actions can make a difference in tackling the climate issue.
Climate change mitigation and Greenhouse gas emissions
the remaining carbon budget for a 50-50 chance of staying below 1.5 degrees of warming is 460 bn tonnes of or years at 2020 emission rates. Global average greenhouse gas per person per year in the late 2010s was about 7 tonnes - including 0.7 tonnes CO2eq food, 1.1 tonnes from the home, and 0.8 tonnes from transport. Of this about 5 tonnes was actual carbon dioxide. To meet the Paris Agreement target of under 1.
