    GIS-Based Emission Analysis Using Car-Borne Sensor Data
    (Proceedings of the 28th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2014) Prummer, Florian; Zita, Masive
    The concept of Extended Floating Car Data (xFCD) allows to analyse traffic-related CO2 emissions by reading out electronics of cars. In urban environments, CO2 peaks caused by traffic congestion or inept traffic infrastructure are of special concern. This paper gives an overview of GISbased methods and workflows that can be applied to xFCD in order to appropriately detect those emission peaks. Based on literature and former studies in related fields, three methods are introduced and applied in a case study to investigate their viability. The results suggest that two of three methods are able to detect these kind of spatial patterns even though the data source is restricted in terms of amount and quality. Furthermore, the paper researches the potential benefits that xFCDbased information products might provide for urban planners in climate protection. Expert interviews with pertinent communities are conducted to gain a well-grounded basis for an assessment. Results of those indicate that the factual need of this information does not yet exist and that according information products only conditionally provide valuable benefits at the moment. The work in climate protection rather focus on projects that address emotional aspects in order to change the mobility behaviour of people. Nonetheless, future legally binding guidelines might also require exact emission quantifications. The concept of xFCD could serve those requirements.

    The Use of Social Media as an Enabler to Create Environmental Awareness of Staff in Higher Education
    (Proceedings of the 28th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2014) Zita, Masive; Burger, Clayton; Scholtz, Brenda
    This paper examines the environmental awareness of staff members in a higher education institution through the use of social media and an environmental awareness campaign. The key question raised is whether the use of social media is an effective tool to run an environmental campaign to raise awareness and evaluate knowledge of the green initiatives that are happening with in the organisation as well as in popular media. The sample used for the campaign consists of academic, professional and support staff at the Nelson Mandela Metropolitan University which boasts an environmentally-friendly core value and has driven a significant amount of research in renewable energy, environmental management, estuarine protection and biodiversity protection, amongst other fields. The campaign was conducted through a centralised website which provided information about environmental management and challenges. The content was provided three times a week with the goal of raising awareness between the start of the campaign and the end, where knowledge interventions were performed to determine a difference in knowledge and social media usage for environmental awareness. The qualitative findings of the campaign through surveys and questionnaires indicate that, despite typical time restrictions, Facebook is the most effective social media platform used use to spread information and initiate “green practices”. Participants indicated an increase of knowledge which was validated through assessment. Coupled with increased knowledge, participants indicated a positive attitude to the subject matter in encouraging them to play a role in the environment. This attitude is thus beneficial in a tertiary learning environment as educators can encourage students to be responsible custodians for the next generation.
