Canopy notices your journeys, food, shopping and digital use, gives you the one swap a day that matters most, and turns the emissions you avoid into leaves that grow a real community grove.
Free for individuals · no ads · your data stays on your phone unless you share it

How it works
Most carbon apps ask you to log things. Canopy notices instead, then keeps it to one useful thing a day.
Walks, rides, trains, takeaways and scans are picked up automatically. You can correct any trip in a tap.
Not fifty tips. The single swap that saves the most, ranked by kilograms, like walking a short trip you usually drive.
Leaves are earned only for emissions you avoided, never for spending. Spend them at local low-carbon businesses; the ones from CO₂ you avoided count toward the community grove.
Every month Canopy plants £20 of real trees for everyone, with Ecologi. Only leaves from CO₂ you avoided count. Trees grow over years, not days, and never offset your footprint, so reducing always comes first.
What it notices
Travel and food are where most everyday emissions are. Canopy shows them biggest, and never gives a tiny thing the same weight as a big one.
10 km by car: 1.7 kg. By Underground: 280 g. On foot: 0 g. UK Government (DESNZ/DEFRA) GHG conversion factors, per passenger-km
Beef: 27 kg CO₂e per kg. Chicken: 6 kg. Tofu: 2 kg. Poore & Nemecek 2018, Science (via Our World in Data)
Grade A: under 1 kg CO₂e per kg. Grade E: over 15 kg. Open Food Facts, Agribalyse life-cycle data
A year of phone charging: ~0.9 kg, about the same as a 5 km drive. UK grid electricity 0.20 kg/kWh (DESNZ/DEFRA) × about 0.012 kWh a charge; low confidence
Why it's different
Every figure in Canopy comes from a published emission factor with its source, year and confidence. Low confidence figures carry a "~" and the word estimate. Nothing is shown with more precision than it has.
Emissions for 10 km, per person, and a whole year of phone charging for scale.
Travel: UK Government (DESNZ/DEFRA) GHG conversion factors. Charging: DESNZ/DEFRA UK grid factor, estimate. Canopy's factors are approximate and are re-checked against the current year's sources before launch. How accurate is it?Privacy
Canopy needs to see your day to be useful, so it is built to keep that day to itself. No ads, no data sales, no analytics on this site.
Location, motion, Health workouts, scans and your footprint are stored on the device. Train stations are matched on the phone too.
Join a league or a household and only what that feature needs is shared: a display name and leaves, never trips, places or kilograms. Receipts are read only with your consent and never stored raw.
If you connect Gmail (UK only for now), Canopy asks Google for read-only access, only to find receipts from takeaways, ride hire and shops and estimate their carbon footprint for you. Personal details are removed on your phone first; the email text is never stored, never sold, never used for ads or to train AI. Disconnect any time. How Canopy uses Google user data
Settings lets you export all your data or delete all of it, including anything on our server. Read the privacy policy
Together
Small steps add up when people take them together. Every social feature ranks leaves earned from avoided emissions, never spending, and nobody sees your trips.
Up to five people share one grove and a combined budget, built only from the days each person chooses to share. Nobody is ranked against their family.
Pick your city from a list (it's never worked out from your location) or start a team with a short code. Leave any time.
Invite a friend with a link. You see each other's name and leaves, and either of you can remove the friendship. No streak-loss nags, and at most one nudge a day.

FAQ
As accurate as the published factors behind them, and no more. Travel uses UK Government (DESNZ/DEFRA) conversion factors, food uses Poore & Nemecek 2018, and scanned products use Agribalyse data from Open Food Facts. Each factor carries a source, a year and a confidence level.
Figures are shown to two significant figures at most. Low-confidence ones, such as digital use or category guesses for a product, carry a "~" and are labelled as estimates. The factors are approximate today and are re-checked against the current year's sources before public launch.
Location, motion and trips stay on your phone. If you connect Gmail (read-only), Canopy finds likely receipts on the phone and you choose which to read; personal details are removed on the phone, the rest is sent to our server only to pull out the order details, and the email itself is never stored. See Google user data in the privacy policy.
Because a tree absorbs carbon over years, not days. An emission you avoid today is gone today, so Canopy always shows ways to reduce first, and only then ways to balance what's left. Trees are planted by partners checked against a recognised standard.
Leaves are Canopy's reward for emissions you avoided: 10 leaves for each kilogram, plus a few for things like the day's biggest win. They never come from spending, and no business can pay for placement.
You can spend them at local low-carbon businesses. Leaves from CO₂ you avoided also count toward the community grove: £20 of real trees Canopy plants every month for everyone.
Everything that reduces carbon is free: journeys, the daily win, takeaways, digital, 10 scans a day, leaves, leagues, friends and the community grove. Canopy+ (£4.99 a month or £39.99 a year) adds a tree planted every month, unlimited scans, weekly insights, household mode, seasonal themes and a member badge.
No. At most one nudge a day by default, no guilt copy and no streak-loss shaming. If you skip a suggestion, it stays quiet for a week.
Both are coming soon, starting in the UK. Store links will appear on this page when it launches. In the meantime, you can reach the founder at founder@ed-any.com.
Canopy is coming soon to iPhone and Android, built in the United Kingdom.
