  1. 1. Collective Sensing WS 2012/13 1CO2Print: Mobile Carbon FootprintApplicationOLOO FrancisMasters in Applied Geoinformatics
  2. 2. Introduction2Collective Sensing WS 2012/13•Carbon footprint: The total sets of greenhouse gases (GHG) emittedto the atmosphere by organizations, products and persons.•Carbon footprint can be measured by calculating Carbon Dioxideequivalence (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. 3. Close Develop a mobile application for mapping CO2footprint, specifically;The application should be able to compute thecarbon footprint generated when travellingThe application should also be able to compute thecarbon footprint generated from daily activities (non–travel related activities)Results should be sharable with others in a networkProject Objectives3Collective Sensing WS 2012/13
  4. 4. Start CO2Print App• Switch phone on• Internet access enabled• Web map enabled• GPS enabledSelect mode of travel• Road (personal car orpublic bus transport)• Rail (electric or fuel-powered train)• Flight class(Economy orbusiness)Start JourneyMeasure travel distance• Use GPS track to calculatedistance• Optionally use differencein coordinates to calculatedistance• Note date• Note Time• Note travel modePlot results• Plot temporal variations intotal footprint• Plot a pie-chart on thecontribution of eachjourney type• Plot latest trip on mapSummary results• Current journey foot print• Long term cumulativefootprint• Summarize distancetravelled in each journeytypeConvert distance (units)to footprint• Use conversion factorsfrom DEFRA1 to calculateCO2e from distance• Conversion based onjourney type• Conversion of CO2e fromnon-travel sources1http://www.defra.gov.uk/publications/2012/05/30/pb13773-2012-ghg-conversion/4Collective Sensing WS 2012/13Story board
  5. 5. 5Collective Sensing WS 2012/13Conceptual ModelCalculator converts distances to CO2e, conversion factors can also be used tocalculate CO2 from non-travel sources. The travel path and footprint can beplotted on the phone.

My FootprintSummary foot print More Details CO2GraphsTemporal variationRoadRailAirCO2 Foot printClose My CO2 FootprintSummary of the recent andcumulative CO2 footprint from allthe modes of travelGraphs analyzing the temporaltrend of individual CO2 footprintand the combination fromdifferent modes of travelDetailed analysis of the resultsincluding total distance traveled,total time travelled and links onhow to offset the foot print12Collective Sensing WS 2012/13
  13. 13. Awareness creationBy introducing CO2Print App in social network siteslike Facebook, users can have a summary of theirweekly CO2 footprints together with the associatedgraphs automatically posted on their status, this canhelp in creating awareness among users.Weekly “honors” can be awarded to members of anetwork who manage to have the lowest amount ofCO2 at the end of each week. Just like, the “Mayor”,in Foursquare, there can be a “CO2 Champion” forthe CO2Print App.13Collective Sensing WS 2012/13How can the App be used in Social Media
  14. 14. Voluntary OffsetAn extension of the CO2Print App in social networkscan also include the ability to offset by paying asmall token which can then be used forenvironmental protection and conservationprograms.Such approaches will not only raise the awareness ofthe users on the impact of individual behavior onglobal climate change, but will also motivate users tostrive to keep low CO2 footprints14Collective Sensing WS 2012/13How can the App be used in Social Media
  15. 15. 15Collective Sensing WS 2012/13ConclusionThe CO2Print App discussed in this presentation is one of the ways in which alocation-aware technology to create awareness on critical subjects like climatechangePlausibility of the results of the application hinge heavily on the accuracy oflocation (and distance measurement) and on the conversion factorsSocial media can be used to leverage on the benefits of the CO2Print App by“advertising” member footprints as a way of motivating network membersThe use of Carbon footprint offsets can contribute towards the sustainability ofthe project and to enable the implementation of tangible benefits by investingthe proceeds in environmental education and conservation projects
