They're a good start but certainly not the be-all end-all. The real solution is a shift away from a spread-out, consumption-driven economy (and global marketplace) and a shift towards more localized production, labor/work, manufacturing, distribution and (eventually) reuse or recycling. The current model is about as stupid and unsustainable as could possibly be devised. People are (slowly) starting to (re)discover that it's actually better, more sustainable and (*gasp!*) more cost-effective to work locally, limit travel, limit consumption and buy regionally where possible as opposed to buying anything and everything (whether needed or not), having insanely long trips just to work or go to school or get groceries, and buying things made as far away as possible because slave labor practices facilitate the desired price point.

We're slowly figuring out that the community-centered model that this country was built on actually works and yields better results. We're a large nation though and there will always be a demand for travel and long-distance transport, the keys are mitigation, management, maintenance of infrastructure and (yes) getting off of non-renewable energy sources as best we can.
