We want to use a calculation to evaluate how many trees are necessary to make a city like Zürich CO2 neutral.
- What kind of trees convert the most CO2 into oxygen?
- How long does it take a tree to convert the full amount of CO2?
- Costs of 1 Three?
- How much space does a tree need?
- Is the number of the trees possible to compensate the whole CO2 emission?
- Is the number of trees required realistic in relation to the amount of space in a city?
We will illustrate our results with a benefit analysis and will explain it in a report. à (Costs, amount of space required, Purchase price, service costs needed)
We will make a survey with random people, friends, and our classmates. à About the CO2 emission per person.
We plan an interview with a person from an organisation, which want to plant trees or to regulate the CO2 in the air over Zürich.
- How much money it will cost, to make a city climate neutral
- What are the main goals?
- When should the target be reached?
- What are the possibilities?
