Cleanest cities in North America

Overview

Seattle tops our ranking of cleanest cities in north america at 8.0/10, just ahead of Vancouver and Honolulu. There's no shortage of blog posts ranking cities from personal impressions. Cleanest cities in North America takes a different approach: the same seven-criterion scorecard, applied identically to every city, so the ranking below is reproducible rather than anecdotal. Ranked purely on our environment score: air quality and pollution levels. We isolated every city in North America from the full 303-city database and sorted that regional subset purely by cleanest, so the comparison stays fair within the region instead of getting diluted by cities on other continents. Guadalajara stands out as the most affordable option in this set (8/10 on cost of living), which is useful context if budget matters more to you than the overall ranking order suggests. Just outside the top three, Calgary, San Francisco, Boston round out a competitive upper half — worth a look if your specific circumstances (a partner's job, a language you already speak, an existing visa route) rule out the leaders. If you've already decided on North America and just need to narrow it down by cleanest, this is the fastest way to do it — for a fuller picture, cross-reference with the overall livability ranking for the same region. Scroll down for the full table — each city name links to its detailed scorecard if you want to dig into the individual numbers.
