Here's your chance not just to be the mayor, but the original city planner as well! Imagine a medium sized city that would be developed with modern, low carbon transportation in mind, and other strategies to reduce the average citizens' carbon footprints.
What would that city look like? Would that make you more likely to want to live there?

Composting
If composting scalable for cities and towns? At what point does transportation outweigh benefits of centralizing waste systems?
Composting might be scalable for cities or towns, but there are a lot of factors that depend on that. The city or town has to have enough space for composting, and there has to be a way to handle and use all of that compost after it is done composting. The compost could be used to fertilize a city farm or a local farm, they could transport the compost with trucks to the farms. So to answer you're question, yes i think it would be possible to compost on a city level.
