I am not sure if my dream requirements are considered sustainable. Some of the posts I see here go a lot farther than I can imagine. I lay down my thoughts, and if it doesn't make sense my apologies in advance.

For a family of 5 my total emissions are 40 t/y. This is already much better than the average in my area per the calculator I used. But I think by reducing car use and making housing efficient, I can bring it down to maybe 10t/y. For this:

• Move to Washington state because the weather is relatively mild and as global warning rages, it would be livable for a long time. Currently I am in CA and between draughts and fires, I think this state is going to be unlivable in my lifetime.
• Housing should be built to offset its emissions completely. I have seen a project near LA that is doing it, so it is possible. Not looking to live a spartan life. Would like to use tech to make things comfortable - solar panels, geo-thermal etc,
• Currently I have a single family home, and I think it is very inefficient. Would like to live in a community where housing is dense and shopping, eating etc. is walkable. I immigrated from India and I really love this model. Hate taking car out every time I need to buy milk or bread.
• Work from home so that commute will also be avoided.
• Do not live in big/expensive areas. Prefer a community that is not as expensive as Seattle area.
• housing to be built to a spec/code that can endure increasingly volatile weather of future. The houses and infra should be built to last several hundred years.

I think there are probably already many projects like this and I would like to be a part of a community, and not a lone wolf.

Last but not the least, I am flexible in my requirements. Will learn and adapt.
