About - Crosswalk Labs
Who we are
Our Story 01
The name Crosswalk is inspired by everyday citizens and leaders who move cities forward — the ones who promote understanding of the issues and drive change. We see you, and we’re here to support your action. Our mission is to make every city-level decision a climate decision.
As former elected officials and data scientists, we’ve seen firsthand how well-informed choices that are grounded in the data can shape communities and affect the environment. We started Crosswalk Labs because we envision communities as the primary drivers of emissions reductions and the center of action.
Our Approach 02
We track 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.
