Economy
OK, in one sense it is all economy, everything we do to provide for our needs, that is what the economy should be about and that is how a green and sustainable economy must be built. It is when you come to finding answers to the question of climate change that Bill Clinton's famous statement 'It's the economy, stupid!' really comes into its own, although we would be more polite!
One aspect of this is money and we have a special page for that Money but more widely we need to consider how we consume and how this affects our carbon output http://transitiontowns.org/Consumption/Consumption.
If we are truly going to build sustainable low-carbon economies we are going to have to start being producers, not just consumers. And I mean producers of the real stuff of life, not advertising slogans and marketing plans.
