Missions on EarthChallenge.com turn a daily habit into a counted result. This page is the running total.
What players on EarthChallenge.com have actually done. Every check-in and approved proof adds one line. The math behind each number is shown on the card, with its source.
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.
Photograph and identify ten wild species (plants, birds, insects, anything) within walking distance of home. Post the list and a link.
+1 actions when approvedCounted as one completed survey. Upload your sightings to iNaturalist or GBIF and your list becomes open biodiversity data.
Counted with SavingTheWorld.org
Plant a native tree where it can survive, or sponsor one through a verified planting program. Post the species, the place and a photo or receipt link.
+1 trees when approvedOne tree. We count trees planted or protected, not carbon, because a sapling's CO₂ uptake depends on survival, species and decades of time.

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.

Seven days with no disposable cups, bottles, bags or cutlery. Carry your own. Check in each night.
+0.1 kg waste per check-inA typical day of single-use items (one coffee cup, one bottle, two bags, one set of cutlery) weighs about 0.1 kg (Ocean Conservancy item weights).

Every night, switch off lights in empty rooms and kill standby power on TVs, consoles and chargers. Check in before bed.
+0.1 kg CO₂e per check-inStandby and lighting waste is ~0.3 kWh per household per evening; at the US grid average of ~0.37 kg CO₂ per kWh (EPA eGRID) that is ~0.1 kg.
Pick one climate or nature problem you can see from where you live. In three weeks, ship a page, a tool, a service or a pilot that moves it. Post the link and what you learned.
+1 actions when approvedCounted as one shipped founder sprint. Entrepreneurs.org reviews these for its builder spotlight.

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.
