If the shortest path in the kitchen to being green is being frugal, what is the obvious green tax policy? Consumption tax! Why Not Shift the Burden to Big Spenders? doesn't cover the environmental implications but is good background.
However, Kitchen Linker has concerns with the way this proposed tax is cooked. It requires reporting of income and savings: new frontiers in zero privacy.
Far better to concentrate consumption taxation on carbon, which has no privacy concerns and very directly attacks the number one global environmental concern (global warming, of course).
Blogs, environment, politics, technology and the kitchen link, often all in one post!
