Crosswalk Labs

Crosswalk Labs tracks greenhouse gas emissions over time with unprecedented resolution — scouring hundreds of data sources, running constrained optimization protocols on billions of data points and benchmarking the results against atmospheric measurements.

We save cities time by providing a detailed, peer-reviewed approach to emissions data validated by atmospheric science — so you know it’s accurate. No more spreadsheets. No more manual processes. Just verifiable metrics you can rely on.

Crosswalk Labs and our data products enable cities to make good on their climate promises.
