CabEasy is a new NYC-based startup that aims to help people share cab and taxi rides inside NYC. For example, a taxi ride to JFK airport from Manhattan can run over $60 -- if you could split the ride in half, now it becomes a bit more reasonable.

When you browse the current ride requests on CabEasy, you are presented with a map and information about the ride request along with information on the emissions that would be reduced by sharing with another person. Here's an example using a ride from the upper west side to JFK airport, "By sharing this cab, you could reduce by 15.71lbs / 7.13kg (est.) the emissions of CO2 of this cab ride !"

The concept behind CabEasy is great and it would be awesome to see a full list of available rides and riders on the service. While I am not sure it will work for short city trips, longer trips to the three city airports and beyond could see more usage. Adding other transportation options would help as well - for example, there are a variety of shuttle bus companies that pickup and dropoff -- could be an excellent addition to the site overall. So if there is no cab to share, there are alternative options to get from point A to point B.
