Missions on ChallengeEarth.com turn a daily habit into a counted result. This page is the running total.
What players on ChallengeEarth.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.
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).

Eat no beef, lamb or pork for seven days. Check in each evening. Fish, chicken and plants all count as a win here.
+1.5 kg CO₂e per check-in1.5 kg CO₂e per day is the conservative gap between a beef-based dinner (~6 kg per 100 g serving) and a plant or poultry one (Poore & Nemecek 2018, Science).

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.

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.

Read your water meter at the same time every day for a week and note the difference. Check in daily.
+1 actions per check-inCounted as one logged reading per day. Knowing your baseline is what makes the next challenge measurable.
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.
