WHY More than 758,506 metric tons of CO2* are used to power vacuums in the US annually. We will reduce emissions by sweeping (then vacuuming if needed). *That's like driving over 1.8 million miles in a passenger vehicle. (Based on 30-minute vacuum use per week/household.)
HOW Sweep dirt up into a pile. Collect the dirt pile in a broom pan. Or, vacuum up just the dirt pile.
