In order to create a fully_transparent_production chain material sources can be mapped. The same can be done for where the material is processed and where it ends up. By logging the location of material sources as well as manufacturing locations, an accurate CO2 embodied energy calculation can be made for each product. Transportation routes can be easily traced and therefore transport emissions easily calculated. As well as Gps location data, each base_unit will transmit how much power is being generated at each location. This will be processed, mapped and logged through the online network branch of the post_fossil_toolkit: the post_fossil_gateway, accessible via www.post-fossil-production-labs.com . By analysing this data, users will be able to optimise their tools across the city. In this way the wider post_fossil_system mimics micro-bacterial metabolic life-cycles and the city is transformed into a self sustaining macro-organism, powered from within itself, continuously evolving and adapting to environmental conditions.
