Measure, manage, and report your buildings' carbon in one place.
CarbonClock gives you one place to gather and track every building's energy data year-round, turns usage into emissions automatically, and gets you ready to report whenever it matters.
Why CarbonClock
From scattered bills to numbers you can stand behind
The problem
You're expected to know your numbers — and report them.
Every building you own or manage is constantly throwing off data: how much energy it uses, what it burns, and the emissions that come with it. More and more, owners and managers are expected to actually know those numbers and be able to report them — to investors, a board, a certification body, or a city. The hard part isn't caring about it. It's getting your arms around the data in the first place.
The mess
Your data lives everywhere.
Electricity in one portal, gas in another, fuel invoices buried in an inbox, and a different setup for every building in the portfolio. Pulling a full year together means chasing down bills, lining up dates, converting usage into emissions with the right factors, and working out what actually counts along the way. Do it once a year from a cold start and it turns into a slow, frustrating scramble — and even then the numbers are only ever as current as the last time someone sat down with the spreadsheet.
The fix
One place. Year-round.
CarbonClock gives you one place to gather and track it all. You enter each building's energy data as the bills come in, and CarbonClock keeps the running picture for you: usage turned into emissions and carbon intensity automatically, full-year coverage tracked so nothing slips through, and a clear dashboard showing where every building stands at any point in the year. You always know what you have — and what's still missing.
The payoff
Reporting becomes the easy part.
With your data in order, reporting is simple — whatever the reason for it. Share progress with investors and ownership, back up a green building certification, or file under a local regulation like Vancouver's Energy and Carbon Reporting By-Law, with other provinces now weighing similar rules of their own. CarbonClock gets each building report-ready and hands you a clean summary to enter into ENERGY STAR Portfolio Manager. So instead of scrambling to answer “how are our buildings actually doing,” you just know.
Everything you need to stay on top of it
From the first bill to the final submission, CarbonClock does the hard compliance work so you don't have to.
One home for all your building data
Good reporting starts with clean data, and clean data starts with one place to keep it. CarbonClock gives every building a single home for its energy and fuel records, entered as they come in instead of being dug up at the last minute.
- Log monthly usage for each energy source, with the billing dates that decide your coverage
- See how much of the year you've covered, and exactly where the gaps are
- Keep utility bills, fuel invoices, and consent forms somewhere you can actually find them again
- Stop rebuilding the same tracking spreadsheet every year
The numbers worked out for you
Forget the conversion tables and the guesswork about which rules apply. CarbonClock turns the energy data you enter into emissions and intensity automatically, and tells each building exactly what it needs to report.
- Region-specific emission factors turn usage into tCO2e and carbon intensity
- Built-in logic works out which reporting category each building falls under
- Plain-language explanations of what each building owes, not regulator-speak
- Numbers update the moment you add new data
Know you're ready before you share data
From the first bill to the final submission, CarbonClock keeps each building's readiness in plain sight. The dashboard catches problems early, and a readiness check confirms everything is in place before you file.
- A dashboard that flags missing data, coverage gaps, and buildings at risk
- A readiness checklist that confirms data, coverage, and documents are all complete
- A clean summary to guide entry into ENERGY STAR Portfolio Manager and your city's reporting system
- Records kept audit-ready, in case the city follows up
One plan, priced per building
Add as many buildings as you manage, and the price scales only with that. Every plan starts with a 30-day free trial, so you can load real data and see real numbers before you pay anything.
