This article presents survey data from households in Alberta, Canada, examining the relationship between income and carbon footprint. Using multivariate statistics to scrutinize the role of income, the data demonstrate substantial disproportionality in the composition and size of household carbon footprints. Results show that household energy consumption (heating, cooking, cooling) comprises half of the average footprint, with automobile transportation contributing 30% and air travel another 15%. In a linear multiple regression model, the size of household carbon footprints is positively associated with income, in addition to other variables. The highest income quintile has household carbon footprints 2.2 times greater than the lowest income quintile.
