Update: I went to the speech today and I'm pretty pumped. Bloomberg is pretty much staking the rest of his days as Mayor and his legacy on this initiative. Read all 127 proposals here

Get ready for some big announcements tomorrow from the PlaNYC 2030 folks. The mayor will be announcing over 100 specific proposals tomorrow on Earth day. And he will most likely call for some type of Congestion Pricing as a way to pay for increased mass transit options and service. The heart of his plan will probably revolve around increasing energy efficiency in buildings and building significantly more new housing.

But I'm really trying to not get my hopes up too much. There will be much political heavy lifting required to make this happen and I think we may have many of the right pieces in place. This is the Big Bang approach to sustainability and by bundling many of these proposals together, Bloomberg is taking a calculated risk that parts of his plan may not make it into reality.

Again, I'm trying to not get my hopes up too much! Stay tuned.
