So you built a green house because you care. Have you considered transit access as well?

To quote from the New Urban Network:

Transit-oriented development is the key to cutting energy consumption — even
more so than Energy Star construction or green cars, according to a
peer-reviewed study supported by EPA.

You decide to build a “green”, energy-efficient house because you really care about energy conservation and preserving the environment you shall build it where there is access to transit. Green cars are not as energy-efficient as transit. Car-sharing, thus maximizing the use of fuel and vehicle is a new concept, and its effectiveness is still tested.

Urban , ‘Brownfield’ developments, have a greater “green” potential than Greenfield ones, because they usually offer greater access to transit. And each new urban development should be in sync with investments into transit infrastructure.

That was once the case in Pittsburgh when land developers also invested in public transportation infrastructure - if we look up the histories of our oldest suburbs and neighborhoods we will note that they were built around or at the same time with a T line or bus route. Maybe that will be the case again in the 21st century though, this time, it will be the buyer to let the land developer know that he cares about transit as well.
