Environmental Doctoral Thesis

This thesis examines the strategic and potentially legitimising nature of voluntary environmental reporting. First, the thesis examines the relationship between emission levels on the National Pollutant Inventory and the quantity of total voluntary environmental disclosures, voluntary emission disclosures and positive voluntary environmental disclosures in annual reports. Second, an examination of changes in the quantity of disclosures discussing compliance with the National Pollutant Inventory and/or disclosures concerning pollution emissions is undertaken.

This thesis adopts an explanatory sequential mixed-approach, incorporating two inter-related studies investigates the resilience capabilities of Hong Kong-based SMEs. Specifically, the overall objective is to empirically examine the multidimensionality of resilience capability, and how each dimension is developed, utilized, and evolved over time and in various contexts. Study 1 involves a survey of 177 Hong Kong-based SMEs and explores the interrelationship between resilience capabilities and firm performance, and the moderating impact of environmental turbulence on these relationships.

This research is comprised of three interrelated stages of a broader study of the climate change-related corporate governance disclosure practices of Australian companies. The first stage of the study investigates the climate change-related corporate governance disclosure practices of five major Australian energy-intensive companies over a 16-year period (from 1992 to 2007). The five companies are BHP Billiton, Caltex, Origin Energy, Rio Tinto and Santos Limited.

This research integrates two distinct theoretical perspectives, business strategy and climate change adaptation. The primary purpose of this research is to explore MNCs’ strategies in regard to climate change adaptation. By interviewing representatives of MNCs operating in both developed and developing countries, as well as analysing company documents, the research offers significant insights regarding existing and future climate change adaptation strategies by MNCs in distinct country settings.

This study seeks to examine the contexts and mitigating circumstances surrounding GI implementation. In particular, it focuses on three main research questions: 1. Why did some GIs fail to achieve positive outcomes while others were able to even acquire competitive advantages from their implementation? 2. Given that some GIs could lead to positive outcomes, why wouldn’t organizations embrace the “winning” approaches when implementing GIs? 3. What were the approaches and conditions that could ensure positive outcomes from GI implementation?
