The purpose of this study was to develop an environmental reporting framework for the Tanzanian industrial sector. To achieve the purpose, the study started by developing a disclosure index, which was used to measure the current extent of environmental reporting in Tanzania. There were two phases in the process of developing the environmental disclosure index (EDI) for the Tanzanian industrial sector. The first phase involved identifying and refining the items for disclosure from the literature. In particular the studies on environmental reporting/disclosure were reviewed and the items to be included in the initial disclosure index were identified. The second phase involved the development of the final disclosure index using the Delphi inquiry method. In the Delphi inquiry, knowledgeable experts in environmental issues were consulted and asked for their opinion on the items proposed, whether the item should be retained, removed or any addition of new item. Therefore, the role of the experts was, first to confirm and validate items to be included in the EDI, and second, to assess the importance of the disclosure of each item by allocating weight to every item. The extent of environmental reporting in Tanzania was measured by using the EDI developed. The annual and environmental reports from various organisations operating in Tanzania were requested and read to determine the current extent of environmental reporting. The results indicated that the information reported by organisations operating in Tanzania mostly came from the categories ‘Organisational context’ and ‘Management performance, policies and systems. The information from ‘environmental performance’ category was left unreported. After the current extent of environmental reporting has been explored, the environmental reporting framework (ERF) was developed. The framework intended to provide guidance on environmental reporting to organisations (from the industrial sector) of any size operating in the country. In particular the framework provided the guidance on four steps to be followed when preparing environmental reports and the content to be included in the reports. After the ERF was developed, it was tested to investigate its applicability using two case studies. The results indicated that the steps to be followed when preparing environmental reports were valid and implementable. / College of Accounting Sciences / D. Phil. (Accounting Sciences)

Due to the fact that corporate environmental reporting (CER) is largely voluntary and unregulated, practice has evolved in the absence of a meaningful conceptual framework. This lack of a normative theory stating what should be the content of CER as well as the methods for measuring reported information being largely volumetric or content based, is advanced as a major limitation in the existing literature. In this study, the wellestablished conceptual frameworks for financial reporting are adapted as the basis for a CER conceptual framework in which four characteristics of CER indicate its quality. Empirical methods for the measurement of such characteristics are also adapted from the financial reporting literature. The main aim of this research is to use the adapted framework to examine the extent of variation in the quality of CER and then to test its applicability to the key motivational theories. The empirical work involves a panel of US and UK firms over a two-year period. This allows cross-sectional comparison to be made between different financial accounting regimes (rules- vs. principles-based) as well as permits examination of the development of CER over time. Further, the empirical work is extended to investigate the interrelationship between the financial and environmental performance of a firm. Evidence in support of the legitimacy and institutional theory explanations for disclosure motivations is comprehensively found through the measures of the qualitative characteristics identified. That is, the use of a novel CER framework based on financial reporting quality here enables a more robust understanding of the reporting behaviours than previous work. Moreover, evidence for CER variation owing to the differences in financial reporting regimes is found and thus, it is reasonable to assert that the culture of financial reporting, to some extent, informs the nature of voluntary non-financial reporting. However, perhaps owing to the short time frame of the investigation, evidence of financial rewards from being environmentally effective or through providing CER is not found. The findings from this research will be of interest to preparers and users of corporate environmental reports as well as to policymakers, particularly in terms of enabling them to assess the quality of reporting and its level of fit with their expectations. Moreover, they also shed light on the link between environmental performance, as manifested in carbon emissions, and what is reported.
