ways to analyse mbt life cycle assessment
- inventory
- impact
- improvement
inventory analysis
provide information about consumption of material & release of wastes from the point that raw material is obtained to make a product to time of its ultimate fate
impact analysis
considers the environmental and other impacts of the product
improvement analysis
determine emasures that can be taken to reduce impacts
three major categories of LCA
- products (thing & commodities consumer uses)
- processes (way in which products are made)
- facilities (infrastructural elements through which products are made and distributed)
difference ecological and carbon footprint
ecological footprint focus on measuring use of bio-productive space and carbon footprint measures emission of gasses
urban metabolism in short
looks at in and output, compares city to a organism
urban political ecology in short
looks at the social effects, which group benefits
three ecologies
- industrial ecology
- marxist ecology
- urban ecology

marxist ecology
power relations form uneven socio-ecological production
