Take well-informed decisions leading to reduced greenhouse gases emissions.
Students are divided into three groups to work on different scenarios and reveal their implications. One group works with the business as usual scenario (energy production and consumption follow the same trends as today). Another group works with a scenario based on the spread of solar energy in which consumption remains the same as today, while the third group works with a scenario in which energy consumption is considerably reduced. The three groups present findings and discuss together what would be the best scenario and route to reduce emissions of greenhouse gases to avoid the 2ºC temperature increase by 2100.
Students then think of three steps/decisions to make in order to work towards this scenario. Discuss why this step and no other? What are the values underpinning this decision? Are there any dilemmas embedded in this step?
