2. Introduction
2Collective Sensing WS 2012/13
•Carbon footprint: The total sets of greenhouse gases (GHG) emitted
to the atmosphere by organizations, products and persons.
•Carbon footprint can be measured by calculating Carbon Dioxide
equivalence (CO2e) (Wright et al, 2011)
•Some software for general carbon footprint measurement include
•Value Chain Manager
•Footprint expert
• One specific mobile carbon footprint application is
• ecorio
3. Close
Develop a mobile application for mapping CO2
footprint, specifically;
The application should be able to compute the
carbon footprint generated when travelling
The application should also be able to compute the
carbon footprint generated from daily activities (non
–travel related activities)
Results should be sharable with others in a network

4. Start CO2Print App
• Switch phone on
• Internet access enabled
• Web map enabled
• GPS enabled
Select mode of travel
• Road (personal car or
public bus transport)
• Rail (electric or fuel-
powered train)
• Flight class(Economy or
business)
Start Journey
Measure travel distance
• Use GPS track to calculate
distance
• Optionally use difference
in coordinates to calculate
distance
• Note date
• Note Time
• Note travel mode
Plot results
• Plot temporal variations in
total footprint
• Plot a pie-chart on the
contribution of each
journey type
• Plot latest trip on map
Summary results
• Current journey foot print
• Long term cumulative
footprint
• Summarize distance
travelled in each journey
type
Convert distance (units)
to footprint
• Use conversion factors
from DEFRA1 to calculate
CO2e from distance
• Conversion based on
journey type
• Conversion of CO2e from
non-travel sources

Conceptual Model
Calculator converts distances to CO2e, conversion factors can also be used to
calculate CO2 from non-travel sources. The travel path and footprint can be
plotted on the phone.

CO2Print App
CO2Print App runs in the
background in the course of a
journey
To start a journey, the user
should select one of the three
travel modes (road, rail, air)
Calculation can also include non-
travel sources
At any time the application
should be able to show a
summary of the CO2 foot print
statistics

Road travel footprint
A user traveling by road can
make a selection depending on
vehicle type, that is ; personal
car/motorbike or public bus
transport
The user should be able to
visualize summary statistics on
CO2 foot print resulting from
road travel

9. Summary train print
Start session
Select train type
Rail pool

Rail travel footprint
A user traveling in a train can
make a selection depending on
the train type of train
The user should be able to
visualize summary statistics on
CO2 foot print resulting from rail
travel

Air travel footprint
A user traveling by air should
make a selection depending on
the flight class whether Economy
of Business
The user should be able to
visualize summary statistics on
CO2 foot print resulting from air
travel

Non-travel CO2 footprint
CO2e can also be calculated
from other sources including
Water use
Lighting
Washing
Cooking
Heating
Refrigeration
This is made possible by the use
of conversion factor

Summary of the recent and
cumulative CO2 footprint from all
the modes of travel
Graphs analyzing the temporal
trend of individual CO2 footprint
and the combination from
different modes of travel
Detailed analysis of the results
including total distance traveled,
total time travelled and links on
how to offset the foot print

13. Awareness creation
By introducing CO2Print App in social network sites
like Facebook, users can have a summary of their
weekly CO2 footprints together with the associated
graphs automatically posted on their status, this can
help in creating awareness among users.
Weekly “honors” can be awarded to members of a
network who manage to have the lowest amount of
CO2 at the end of each week. Just like, the “Mayor”,
in Foursquare, there can be a “CO2 Champion” for
the CO2Print App.

How can the App be used in Social Media
14. Voluntary Offset
An extension of the CO2Print App in social networks
can also include the ability to offset by paying a
small token which can then be used for
environmental protection and conservation
programs.
Such approaches will not only raise the awareness of
the users on the impact of individual behavior on
global climate change, but will also motivate users to
strive to keep low CO2 footprints

Conclusion
The CO2Print App discussed in this presentation is one of the ways in which a
location-aware technology to create awareness on critical subjects like climate
change
Plausibility of the results of the application hinge heavily on the accuracy of
location (and distance measurement) and on the conversion factors
Social media can be used to leverage on the benefits of the CO2Print App by
“advertising” member footprints as a way of motivating network members
The use of Carbon footprint offsets can contribute towards the sustainability of
the project and to enable the implementation of tangible benefits by investing
the proceeds in environmental education and conservation projects
