- Agriculture and food consumption are identified as one of the most important drivers of environmental pressures, especially habitat change, climate change, water use and toxic emissions.
- The use of fossil energy carriers for heating, transportation, metal refining and the production of manufactured goods is of comparable importance, causing the depletion of fossil energy resources, climate change, and a wide range of emissions-related impacts.
- The impacts related to these activities are unlikely to be reduced, but rather enhanced, in a business as usual scenario. This study showed that CO2 emissions are highly correlated with income. Population and economic growth will hence lead to higher impacts, unless patterns of production and consumption can be changed.
- Furthermore, there are certain interlinkages between problems that may aggravate them in the future. For example, many proposed sustainable technologies for energy supply and mobility rely for a large part on the use of metals (e.g. in batteries, fuel cells and solar cells). Metal refining usually is energy intensive. The production of such novel infrastructure may hence be energy-intensive, and create scarcity of certain materials, issues not yet investigated sufficiently. There is hence a need for analysis to evaluate trends, develop scenarios and identify sometimes complicated trade-offs.
In the online description, they use the terms "agriculture and food consumption." But listen to what they have to say in this video, mostly filmed at the launch of the report. Please share this with your friends and climate change adversaries alike (http://www.youtube.com/watch?v=tQlekfaPyaA).
