One way of reducing carbon emissions is to reduce carbon emissions from consumption. Quantitative information about these emissions helps to better understand the reduction potential. This article aims to provide carbon footprint data for students of the University of Applied Science in Konstanz, Germany. The study includes almost 10% of the University’s students. Data on emission patterns was collected via questionnaires and calculated by a web-based carbon calculator. The study analyses personal carbon footprints and, more detailed, carbon emissions from consumption categories heating, electricity, mobility (land travel and aviation) and food. The findings show average students’ annual carbon footprint to be10.9t CO2eq and in the same order of magnitude as the German average. While students cause less emissions through heating because of smaller living space per person, they cause significantly more emissions by aviation. Female students tend to have higher emissions from aviation, instead male students have higher emissions from food (due to more meat in their diet). Business students have higher emissions than others, mainly because they are tending to fly more. The student carbon footprint is far above climate protection goals formulated for 2050.
Um im Angesicht der Klimakrise eine lebenswerte Zukunft zu sichern, brauchen wir einen grundlegenden und raschen gesellschaftlichen Wandel. Wirksame Klimakommunikation kann eine wichtige Rolle spielen, um das für diesen Wandel erforderliche gesamtgesellschaftliche Engagement zu fördern.
Im Forschungssemester wurden drei Ziele verfolgt: Erstens der Auf- und Ausbau des eigenen Kenntnisstands zur Klimakommunikation, zweitens das Kennenlernen der Arbeitsmethoden und -kultur des gastgebenden Think-Tanks Climate Outreach sowie drittens die Erstellung eines oder mehrerer für die Nachhaltigkeitstransformation nützlicher ‚Produkte‘ als Ergebnis des Forschungsaufenthalts. Alle drei Ziele konnten erreicht werden. Dabei bilden ein Working Paper, ein 4-Seiter für Praktiker sowie mehrere Artikel und ein Buchkapitel die Arbeitsergebnisse für andere nachvollziehbar und anwendbar ab (siehe Liste entstandener Veröffentlichungen in diesem Bericht).
Inhaltlich war die Kernerkenntnis, dass Menschen sich ihre Meinung zum Klima und der eigenen Rolle in der Transformation nicht in erster Linie durch mehr und bessere Informationen bilden, sondern durch Geschichten, die ihre Werte ansprechen, die von Menschen erzählt werden, denen sie vertrauen, und die durch die Überzeugungen und das Verhalten der Menschen in ihrem Umfeld bestätigt werden. Klimakommunikation sollte also neben der rationalen Vermittlung von Fakten auch unsere emotionale Seite bedienen und beispielsweise zeigen, wie sich soziale Normen verändern und Klimaschutzhandeln zum neuen Normal wird.
Per-capita greenhouse gas emissions in cities like Bangkok or Shanghai have already reached emission levels of cities like London or Toronto. Large parts of the building stock and service infrastructure in cities in rapidly developing countries will be built in the coming decades—and may lock in high emissions pathways. A survey of projects under the Clean Development Mechanism (CDM) of the Kyoto Protocol shows that only about 1% of projects have been submitted by municipalities, mostly in the waste management and more recently in the transport sector. This is probably due to a lack of technical know-how, legal barriers, methodological challenges, long project cycles and limited “visibility” of projects for the electorate. A case study of city network ICLEI’s experience with the CDM adds practical insights. We conclude that while the new market mechanisms under Article 6 may make it easier for municipalities to engage in international market mechanisms, new forms of cooperation between actors on multiple levels, potentially facilitated by ICLEI, are required to help to realize the urban potential in international market mechanisms.
This report summarises up-to-date social science evidence on climate communication for effective public engagement. It presents ten key principles that may inform communication activities. At the heart of them is the following insight: People do not form their attitudes or take action as a result primarily of weighing up expert information and making rational cost-benefit calculations. Instead, climate communication has to connect with people at the level of values and emotions.
Two aspects seem to be of special importance: First, climate communication needs to focus more on effectively speaking to people who have up to now not been properly addressed by climate communications, but who are vitally important to build broad public engagement. Second, climate communication has to support a shift from concern to agency, where high levels of climate risk perception turn into pro-climate individual and collective action.
