Bruce Finley had an interesting article in the Denver Post in January, that covers all sources of various greenhouse and other polluting gases. Interesting graphs if you happen to live in Colorado. What was curious to me was this:
“The biggest nitrogen oxides polluters include power plants, topped by the Tri-State facility in Craig (6,677 tons) and Colorado Springs’ Martin Drake plant (1,293 tons), along with multiple oil and gas industry polluters and others, including Vail Resorts’ Keystone ski area.”
Naturally, I wondered, “what’s this about?” and “why Keystone and not the other ski areas?”. I emailed Bruce and he said that Keystone made the top 20, and he was also curious and double-checked with the State. Apparently the use of generators and other equipment emits these gases.
Hopefully others more familiar with Colorado ski areas will know something about why Keystone is different. If not, I’ll do some more scratching around.
