Local missions are things you can do where you live — in Columbus that means your own street, shoreline or school. Global missions add up across every arena on the network.
Rinse and sort every recyclable item for a month, and learn what your local program actually accepts. Check in daily.
+0.5 kg waste per check-inThe average US household discards about 2 kg of recyclable material a day and captures only a third of it (EPA Facts & Figures). Sorting everything diverts ~0.5 kg more per day.
Keep food scraps out of the bin for three weeks: a backyard pile, a worm bin, or your city's green cart. Check in daily.
+0.25 kg waste per check-inAmericans waste about 0.27 kg of food per person per day (EPA). Composting it keeps that out of landfill, where it would release methane.
Keep every piece of plastic you throw away for seven days, then sort, count and photograph it. Post the count and the three items you will swap.
+1 actions when approvedCounted as one completed audit. Most people find 60 to 100 items. The swaps you choose feed the Zero Single-Use Week.

Seven days with no disposable cups, bottles, bags or cutlery. Carry your own. Check in each night.

Spend an hour clearing litter from a beach, riverbank, park or your own street. Post a photo link or a short note with the spot and roughly how much you collected.
+4 kg waste when approvedOne full standard trash bag of mixed litter weighs about 4 to 6 kg (Ocean Conservancy International Coastal Cleanup averages). We count 4 per approved cleanup.

Daily briefingClimateNews.comThe climate newsroom of the network: what moved today, with sources, so the daily round has something real to ask about.
Check-ins are self-reported and shown as logged. Proof missions are reviewed by a person before they count as verified. Each per-action figure is a conservative public estimate (EPA, IEA, UN Environment or peer-reviewed sources named on the card), rounded down. These numbers are for keeping score and staying honest, not for carbon accounting or offsets. If you think a figure is wrong, say so on the contact form and we will fix it in public.
