    Standardisation of XML-based DTDs for Corporate Environmental Reporting: Towards an EML
    (Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Lenz, Christian; Isenmann, Ralf; Marx-Gomez, Jorge; Krüger, Mario; Arndt, Hans-Knud
    Discussions concerning companies’ environmental aspects gained considerable importance and challenged business in recent years. Comprehensible and authentic as well as customised corporate environmental reporting requires substantial quantities of relevant information. In order to automate corporate environmental reporting, the presented approach focuses on structuring and standardising environmental documents using the eXtensible Markup Language (XML). In a more detailed fashion, the contribution is dealing with the harmonisation of three current XML-based document type definitions (DTDs) proposed for internet-based corporate environmental reporting. From an academics’ point of view, this harmonisation is thought to be a considerable effort: firstly, for contributing to the discussion of standardising corporate environmental reporting taken as a whole, and secondly, for stimulating the processes towards shaping an Environmental Markup Language (EML). From a practitioners’ perspective, such a standardised XML-based DTD contributes to employ Internet technologies and Internet services productively for corporate environmental reporting. Reporting companies and their target groups are enabled to exploit the huge opportunities and media-specific technical benefits efficiently. The paper is structured in four parts: The first part deals with the design process used to develop each DTD. In the second part, the three DTDs are presented in a more detailed fashion. Based on this, the third part refers to the process of harmonisation of the proposed DTDs. The paper ends with a conclusion.

    Target Group Tailored Corporate Environmental Reporting— Stereotyping, Individualisation, Personalisation
    (The Information Society and Enlargement of the European Union, 2003) Isenmann, Ralf; Brosowski, Jan; Lenz, Christian
    Bei der betrieblichen Umweltberichterstattung spielt die Zielgruppenspezifizierung eine zentrale Rolle. Sie entscheidet wesentlich darüber, ob die anvisierten Empfänger wie z.B. Mitarbeiter, Kunden, Behörden, Umweltschutzinitiativen und Investoren Umweltberichte tatsächlich beachten, inwieweit sie diese Publikationen als Informationsquelle nutzen und in welchem Ausmaß sie die darin veröffentlichten Inhalte für ihre Entscheidungen berücksichtigen. Eine zielgruppenspezifische Umweltberichterstattung stellt insofern eine theoretisch anspruchsvolle, in der Unternehmenspraxis aber bislang kaum eingelöste Anforderung dar (Abschnitt 1). In diesem Beitrag werden hierzu konzeptionelle Grundlagen gelegt sowie eine informationstechnische Umsetzung anhand von drei Bestandteilen vorgestellt (Abschnitt 2): Zunächst sind die anvisierten Empfänger von Umweltberichten festzulegen und deren spezifischer Informationsbedarf zu analysieren. Die Analysen bilden die Basis zur Entwicklung zielgruppenspezifischer Nutzerprofile (Abschnitt 3). Aufbauend auf diesen vorgeschalteten Analysen wird eine XML-basierte Dokument Typ Definition (DTD) zur Umweltberichterstattung entwickelt. Diese DTD repräsentiert sozusagen das Informationsangebot des berichterstattenden Unternehmens (Abschnitt 4). Danach läßt sich Informationsbedarf und Informationsangebot in einem Umweltberichterstattungssystem zusammengeführen. Dabei wird zwischen drei Stufen der Zielgruppenspezifizierung differenziert: Stereotypenansatz, Individualisierung und Personalisierung. Zur IKT-Umsetzung wird das Java-basierte Publishing-Framework Cocoon genutzt, illustriert am Beispiel der Individualisierung (Abschnitt 5).

    The Future of Corporate Environmental Communication: Trends, Contents, Media, Technologies
    (Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Isenmann, Ralf; Lenz, Christian; Müller-Merbach, Heiner
    The various developments within the field of corporate environmental communication are arranged to a comprehensive and reasonably structured survey. On the one hand, from an academics’ perspective, this survey offers an overview of recent literature and empirical studies in the field. On the other hand, from a practitioner’s point of view, helpful guidance is provided how to employ the Internet and other associated technologies productively. The survey focuses primarily on environmental aspects; it is based on rising challenges by which companies are more and more confronted. However, the general insights can be transferred also to financial, social, or sustainability communication seen as a currently emerging phenomenon towards an integrated approach containing financial, environmental, and social aspects, in particular their mutual interrelations. According to the pioneering effort of structuring the multitude of developments, it appears useful to describe the overall contours in a basic framework. In a more detailed fashion, the framework rests on a set of four substantial categories, illustrated by four characteristics that are relevant for the field of corporate environmental communication on the whole. This framework includes: (i) current trends representing the major developments, tendencies, and determinants for progress, (ii) important contents representing essential subjects, crucial themes, and critical issues companies and target groups are communicating, (iii) various media like hypermedia, multimedia, print media etc. used for corporate environmental communication, and (iv) the professional employment of information and communication technologies (ICT) and its applications, in particular the technical benefits by employing Internet technologies and Internet services. The proposed framework should be regarded as schematic, not photo-realistic. However, it is helpful to highlight substantial differences between outdated, very early stages of managing corporate environmental communication e.g. by providing simple “green glossy brochures” on print media or just put by Portable Document Format (PDF) on the Internet for the sake of merely smart presentations in contrast to a forward-looking environmental communication system often called a “sustainability communication system” or a “cybernetic communication system”. As such, a cutting-edge environmental communication system offers a set of appropriate contents (customised information and personal reports on demand), media (print media, Internet, CD-ROM), presentation styles (target group tailoring), and distributing principles (push, pull) by an efficient manner. In terms of corporate environmental communication, taking the four categories into account will improve the way in which companies give environmental information, communicate environmental related topics, and manage their environmental management internally and externally. By so doing, such a corporate environmental communication system may be beneficial for all members involved that are reporting companies, key target groups addressed, and other stakeholders involved like standard setting institutions, and benchmarking organisations.
