Max Heiman of Rockefeller University's "How Green R U" blog points out one thing that's missing from Mayor Bloomberg's PlaNYC: a mandate for improving the fuel efficiency of New York's taxis. The city has begun experimenting with a small number of hybrid taxis, and as Heiman argues, the logic for converting the whole fleet is pretty compelling:

As this op-ed in the Times City section points out, there are nearly 13,000 taxis in NYC, together driving on the order of 800 million miles per year. More than 9 out of 10 cabs on the street are Crown Vics, which are lucky to get 18 mpg.

The entire fleet turns over every three years, so a fuel efficiency standard put in place today would convert every taxi in the city to a higher standard by 2010. The authors say that the Taxi and Limousine Commission has looked at hybrid taxis that get 39 mpg and average just about $2500 more than the Crown Vic, while saving $3700 in gas each year.

This just seem like a no-brainer to me, and I don’t get why it wasn’t in Bloomberg’s plan.

I agree.
