Question 1

IPCC

Answer 1

Intergovernmental Panel on Climate Change (Physical Science Basis)
High growth, Middle course, Ecology driven:
Population, primary energy demand (Gtons Oil Equivalent), Net Carbon Emissions,

Question 2

Temperature increase

Answer 2

Until 1850 slight variations, after fossil fuels –> increase in global surface temperature.
2-5 degrees increase

Question 3

Ecological Footprint

Answer 3

Amount of land to produce enough food and, at the same time, absorb waste.
** Meat, food packaging, type of house, people, percentage of renewable sources of electricity, car efficiency, distance, flying.
1. Estimate consumption.
2. Convert consumption into land/water area to produce or absorb OR land for mines, tools, or materials.
3. Add up the individual contributions of a community.
In the countries that pollute a lot, there are usually few square meters for each person (densely populated countries).

Question 4

MIPS

Question 5

Environmental indicators

Answer 5

• Biodiversity: % of land as protected area
• Energy use: GDP per unit energy ($ per unit)
• Water use : Intensity of freshwater use

Comparable and scientifically proven.

Question 6

Classification of indicators

Answer 6

• Stock f(x)
• Change f’(x)
• Distribution F(x)
• Composite.

Question 7

advantages of energy footprint

Answer 7

• Simple, one planet (countable resource)
• Concentrates energy and material into a single qty.

Question 8

Disadvantages of energy footprint

Answer 8

• Densely populated areas are perceived as parasitic.
• Tends to reward the replacement of natural environments with high productivity monoculture (to produce resources).
