This bar chart shows the percentages of people who engaged in six behaviors (each of which can reduce carbon emissions): reducing food waste, reducing meat consumption, buying carbon offsets, installing a heat pump, installing rooftop solar panels, or buying or leasing an electric vehicle. Overall, the behaviors that have a lower initial cost (such as reducing food waste and meat consumption) are much more common than behaviors that entail large initial cost (such as converting to heat pumps and purchasing electric vehicles).
