- To compare various carbon calculators available on the
Internet
- Seven carbon calculators are described and evaluated 5
Swedish and 2 foreign
- A special marking scale is suggested
- The results are expected to serve as a guide when
choosing a carbon calculator on the Web

- Housing
– House type , family size, electricity/energy consumption… – Fuel mix in specific country is crucial
- Transportation
– car and flight habits; sometimes more details about all vehicles: motorcycles, boats, trams…
- Lifestyle
– indoor temperature, food habits, recycling…
15-25 % 25-30 % ~ 50 %

Emissions caused by the Albert’s family vs total marks for every carbon calculator
SLIDE 16
Lund University / LTH / Energy Sciences
- Carbon calculators differ a lot in their results
- Useful as a tools for the comparison of CO2 emissions
- Useful as a way to learn about our environmental impact
- Still impossible to conduct an accurate marking and ranking
- Rating criteria are subjective: other conditions and assumptions
would lead to another results
- “Carbon footprints” on the computer screen are not an absolute
truth but can be used as a tool for ones own comparison, judgement and behavioural change
