Abstract [en]

Climate persuasive services, a type of persuasive technology, could benefit significantly from having a well designed goal-setting feature to actually get users to reduce their carbon emissions. This study explored monthly carbon budgets as a tool for goal-setting to motivate carbon emission reductions. The study focused on how self-efficacy and reflections from budgeting carbon affected motivation.

A prototype for a carbon budget planner was developed for the study and was designed to only motivate users intrinsically so external rewards or prompts were avoided in the design. Participants in the study got to use the prototype and were interviewed around the themes of reflection, self-efficacy and motivation.

The results proved it difficult for the participants to plan the monthly carbon budget as there were different ways to think about it. Though most of the participants were aware of their climate impact, the carbon budget planner gave them new perspectives on their carbon emissions and lifestyle. Different calculation methods between the climate calculator and the prototype made it uncertain if participants actually felt they could keep a budget which reduced their emissions. In the end almost all participants felt more motivated to reduce their carbon emissions after the study.

Abstract [sv]

Climate persuasive services, en typ av persuasive technology, skulle kunna dra nytta av att ha en väl utformad målsättningsfunktion för att få användarna att faktiskt minska sina koldioxidutsläpp. Den här studien utforskade månatliga koldioxidbudgetar som ett verktyg för målsättning för att motivera koldioxidutsläppsminskningar. Studien fokuserade på hur upplevd självförmåga och reflektioner från budgetering av koldioxid påverkade motivation.

En prototyp för en koldioxidbudgetplanerare utvecklades för studien och utformades för att endast ge inre motivation till användarna så externa belöningar eller prompter undveks i designen. Deltagarna i studien fick använda prototypen och intervjuades kring teman av reflektion, upplevd självförmåga och motivation.

Resultaten visade att det var svårt för deltagarna att planera den månatliga koldioxidbudgeten, eftersom det fanns olika sätt att tänka på det. Även om de flesta deltagarna var medvetna om deras klimatpåverkan gav koldioxidbudgetplaneraren deltagarna nya perspektiv på sina koldioxidutsläpp och sin livsstil. Olika beräkningsmetoder mellan klimatkalkylatorn och prototypen gjorde det osäkert om deltagarna faktiskt kände att de kunde hålla en budget som minskade utsläppen. I slutändan kände nästan alla deltagare sig mer motiverade för att minska sina koldioxidutsläpp efter studien.
