> Because of the requirement that it fuel the entire fleet within an hour in the event of a snow emergency, natural gas hasn’t proved practical especially since CNG fueling stations require too much space in such a dense city, according to Commissioner Garcia. Right now the fleet is about to undertake initial testing with renewable diesel, which is not only better in terms of greenhouse gas emissions, but can be used as a complete replacement for diesel, not just as a 5 to 20% blend.
So they already forwent CNG (unlike most municipalities) because of this requirement.
