What Earth Challenge Does
Big environmental problems need many hands and a scoreboard. This entity runs those challenges.
Seven days of cutting what you throw away, with a daily task list.
A month of measurable cuts to home and commute energy use.
Thirty days of lower-impact eating without going hungry or preachy.
Two weeks tracking and trimming household water use.
Run any challenge as a workplace, classroom, or friend group with a shared board.
Completion records you can point to when the challenge ends.
How Earth Challenge Works
Choose a topic and a length that fits your life — a week, a month, or a season.
Every day has one concrete action and a place to log it.
See your totals, your team's board, and what to take on next.
Counted actions only. Your entry joins the running total below and the method is published with it.
Why this exists
This venture covers materials for participants in places where the challenge would otherwise be unaffordable to enter.
Nothing counted yet. This page will show the running total as soon as there is one.
Reported by SavingTheWorld.org, where the network's impact commitments are tracked.
About
EarthChallenge — Planet-scale challenges, run properly. Part of the VentureOS network of 20,000+ smart entities, each built to create real value in its vertical. Backed by 63+ specialist agents, shared infrastructure, and a unified economy.
The core challenges are free to join; you supply the effort. Optional team boards are the only paid layer.
Challenges are pass-by-completion, not streak-perfect. Miss a day, log it, keep going.
Each task lists its estimated effect and its source, so you can judge the size of the win for yourself.
