Time-boxed climate challenges for teams, schools and cities — with a public result.
Free for early members. No credit card required.
What Climate Challenge Does
Pledges are unmeasured. A challenge has a start, a scoreboard and an end, which is what turns intent into a number.
Meat-light months and low-waste kitchens, with the impact math shown per meal.
Train-over-plane and bike-to-work challenges, counted trip by trip.
A month of measured reductions: thermostat, standby loads, laundry habits.
Seven days of tracking everything you throw away — then shrinking it.
Households, classrooms and offices running the same sprint on one board.
Every challenge shows its working — which actions are big, which are symbolic.
How Climate Challenge Works
Food, travel, energy or waste — pick the 30-day challenge that fits your life.
Track the challenge's one number daily; the math pages convert it to impact.
See your month against the baseline, then stack the next sprint on top.
Counted actions only. Your entry joins the running total below and the method is published with it.
Why this exists
This venture funds entry for participants who cannot afford the equipment a challenge requires, so measurement is not limited to people who already had the means.
Nothing counted yet. This page will show the running total as soon as there is one.

About
ClimateChallenge — Measurable climate action, run as a challenge. 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.
Some matter much more than others — which is exactly what the honest-math pages show. The challenges focus effort on the actions with real weight.
Each challenge defines its own simple count — meals, trips, kilowatt-hours, bags — logged daily so the end-of-month change is visible.
Yes — team leagues run the same sprint across a group with a shared scoreboard and a combined total.
From the Network
Not a website. Not a landing page. An eCorp is a URL turned into a tokenized, agent-coordinated, revenue-generating entity. Here's the unpacked definition.
Read →One operator, one OS, one network — how VentureOS turns 20,000 dormant domains into 20,000 live eCorps over the next 12 months.
Read →We shipped amber v2.0 with a dark cyberpunk palette. The Founder called it cold and non-engaging within 60 seconds. Here's what we learned about warm design and human trust.

Every eCorp in the VentureOS network is purpose-built, agent-coordinated, and connected to the ones it depends on. Follow the threads.
