Our group developed an app that calculates carbon emissions from transport to help individuals make informed decisions about their travel choices. To find the nessesary data and statistics to calculate the emission, we used a carbon footprint analysis. This methodology involves calculating the total greenhouse gas emission associated with different transport alternatives. By using a carbon footprint analysis we can provide a comprehensive view of an individual's environmental impact, including indirect and direct emission.


Our methodology

Here is the methodology used for gathering data for the Carbon App. The methodology is based on collecting real data on carbon emissions. The students involved in this project have been thorough and have searched for scientifically-based data. The development of the formulas used in the app was done by the students and is explained in detail. Our aim with the Carbon App is to increase people's awareness of their daily carbon emissions and encourage them to take steps to reduce it.

Cars

Gasoline:
According to SSB.no, an avarage gasoline driven car emits
157,47g CO\(_2\) per km.

\[{0,157kg \times km} \over Passengers \] Diesel:
According to SSB.no, an avarage diesel driven car emits
130,09g CO\(_2\) per km.

\[{0,130kg \times km} \over Passengers \] Hybrid:
From transportsenvironment.org there has been estimated that an avarage hybrid plug in car emits 152g CO\(_2\) per km.

\[{0,152kg \times km} \over Passengers \] Electric:
According to SSB.no, an avarage electrical driven car consumes
0,2 kWh per km. Generating 1 kWh with fossil fuels emits 0,388 kg of CO\(_2\)

\[{0,2 kWh \times km \times 0,388 kg CO_2} \over Passengers \]

Busses

Diesel:
According to SSB.no, an avarage diesel driven bus emits
855,4g CO\(_2\) per km.

\[{0,855kg \times km} \over Passengers \] Biodiesel:
According to framtiden.no an avarge biodiesel driven bus emits 14g of CO\(_2\) per person km.

\[{0,014kg \times km}\] Electric:
According to Sustainable-bus.com, an avarage electrical driven bus consumes 1,745 kWh per km. Generating 1 kWh with fossil fuels emits 0,388 kg of CO\(_2\)

\[{1,745 kWh \times km \times 0,388 kg CO_2} \over Passengers \]

Other electrical transports:

A grown man that weighs 80kg and is 180cm tall, bicycling in the city
will use energy worth of 0,037 kWh. (here we could convert to juuls and tell how much he would need to eat??)

El-kick-scooter:
Electrical Two Wheels states in their product catalog that their El-kick-scooter on an avarage consumes 0,006kWh. Generating 1 kWh with fossil fuels emits 0,388 kg of CO\(_2\).

\[0,006 kWh \times km \times 0,388 kg CO_2\] El-bycycle:
According to tredz.co.uk, an electrical bike with maximum capacity of 400 Wh will be last for 80km on an open road, with good road surfaces and a steady pace. \({400 Wh \over 80km} = 5 Wh = 0,005 kWh \) per km. Generating 1 kWh with fossil fuels emits 0,388 kg of CO\(_2\)

\[0,005 kWh \times km \times 0,388 kg CO_2\]

Airplain

Business class: According to framtiden.no, each person sitting in business class is responsible for 298g of CO\(_2\) per km.

\[{0,298kg \times km}\] Economy class: According to framtiden.no, each person sitting in economy class is responsible for 133g of CO\(_2\) per km.

\[{0,133kg \times km}\]

Walk

A grown man that weighs 80kg and is 180cm tall, walking in a pace of 4 km/h will use energy worth of 0,065 kWh. (here we could convert to juuls and tell how much he would need to eat??)

Trains

According to framtiden.no an avarage train emits 45g of CO\(_2\) per person km.

\[{0,045kg \times km}\]
