Green building can give part of the answer for zero carbon emissions from the building sector. But what would a truly zero carbon building look like that had no carbon impact at all from construction, through occupancy through demolition?

What Part of 'Global Warming' Don't We Get?

Forget about the hurricanes. Put them out of your mind. We'll never know for sure that any particular hurricane is caused by global warming, so just don't think about them. Instead, concentrate on the other evidence for climate change that's appeared recently:

Recently, we had one of our commenters, Zeno Swijtink, of Sonoma State University, say that biodiesel might not be all that great from a carbon neutral point of view. He said:
Running a vehicle on biodiesel does not give 100% GHG reduction in my bookkeeping. Biodiesel is a carbon fuel and the atmosphere does not care where the released greenhouse gasses came from. The usual argument that the biodiesel carbon partakes in the short carbon cycle while gasoline carbon partakes in the long carbon cycle is, I believe, fallacious. CO2 uptake thru both these cycles does not care how the CO2 was released. So to assess our progress towards GHG reductions we need to count release from biodiesel oxydation at their full value when we estimate anthropogenic GCC.
The way to answer this is to look at the carbon cycle:

I think that sometimes a "knee jerk" reaction of environmentalists is, "Let's pass a law!" However, especially in protecting the commons, there is no easy way to incentivize the desired behavior. So I propose that there is some minimum set of regulations that will be required for communities to pass, in order to significantly reduce GHG emissions from new development, from existing building stock and from transportation.
These new regulations are:
1. A green building ordinance
2. A "energy efficiency upgrade on remodel or sale" ordinance
3. A carbon tax
4. Land use/zoning regulations

Did some more analysis on temperature data in Sonoma County. This time the data is from the Santa Rosa C weather station, and goes back to 1950. Santa Rosa is the biggest city in Sonoma County, and has experienced the largest population growth. Interestingly, this data also shows warming, about 2 degrees, in the average of annual high and low temperatures
However, there is a fundamental difference with the Graton data.
