I don’t think we can fall back to strictly local enterprises and locally sources products and services because this isn’t necessarily the most efficient use of limited resources. Global sharing of resources and ideas (and global repairing of ecosystems) is necessary to avoid dropping into a very dark place and is more secure for everyone involved.

In this regards I think the P2P and collaborative consumption models are essential, but I also think that we need a way to tie our concept of value intrinsically to planetary ecosystems.

A resource for storing and transmitting this value could be documented global warming preventive activities.
These have four essential qualities:
1. They represent a real and common economic and survival need of everyone on the planet;
2. They have a measurable physical basis with universal standards of accounting signed off on my the UN and all governments;
3. They are democratically accessible to nearly everyone;
4. They are an indicator of goodwill because the have a non-discriminatory benefit.

This value can be captured through locally issued ‘Emissions Reduction Currency’ provided that the well established IPCC and ISO accounting practices are adhered to. There is no need to engage the political process in establishing them. They can be self funding through inclusion of advertising on notes. While being issued locally they can be exchanged globally on the basis of the quantity of CO2-equivalent global warming prevention that they represent. They can start small and ‘scale’ up organically as liquidity and acceptance in the economy increases. They can provide a certainty of revenue in areas that lack access to other items of value to the general economy and can be used in this way as an adaptive measure and safety net for otherwise impoverished communities.
