There is a strong link between income and emissions of carbon dioxide. Your “carbon footprint,” or how much carbon emissions your activities produce, is highly correlated with how much you earn. The more money you have, the more you can spend on things like goods, travel, properties, etc.

But that is not the whole story. Many people can and do reduce their carbon output by changing their spending habits. Of course, individuals are not the only ones who produce emissions – companies and governments do too, often at a much greater scale. But scientists say even small, individual reductions to emissions can be important.

Use the calculator below to estimate your carbon emissions, and how you compare to other households, based on how you spend your money.
