Furthermore, in the last few decades, oil and gas companies have been accused of green washing' in their marketing campaigns and corporate reports (Pulver, 2007), and concerns have been raised over their sustainability policies and practices. Reduced profits have resulted in some oil and gas giants drastically reducing their spending on high capital renewable energy (solar and wind energy) to focus on investments with better returns, such as bio- fuel technologies and cleaner ways of using fossil fuels, which are far from "green' (Webb, 2009) This is reflective of a weak sustainability" position that de-emphasises environmental values and social justice, while overemphasising efficient use of materials and energy (Ball and Milne, 2005). However, in view of human dependence on non-renewable energy, which leads to the oil industry's continued existence, any effort to reduce the negative impact of such a destructive industry, however minimal, should not be undermined.
