Plastic Footprint

One tool, from a startup called Omni Calculator, asks simple questions about a typical week, tallying up how many plastic bottles or takeaway boxes or yogurt containers you use, and then telling you roughly how many pounds of plastic you use in a year or that you’ll use in your lifetime.

Another, from Greenpeace’s U.K. office, adds up the number of plastic items you buy and then forces you to scroll through a visual representation of your annual pile of trash.

An app called My Little Plastic Footprint goes further, helping users track their progress toward zero waste over time.

Act responsibly. Progress toward zero waste.
