It interests me that BHP Billiton (the world’s largest coal exporter) is adjusting its port construction plans to account for the effects of climate change on ocean behaviour. They are also looking carefully at further investments in coal given they anticipate a movement away from coal. As a firm they are committed to addressing the risks of climate change and to exploring the business opportunities climate change creates. In terms of intelligence BHP Billiton and many other responsible corporates (lets leave Gina R. out of that categorization) are more intelligent and far-sighted than out conservative politicians. Its not just vision and responsibility either – its good business and showing concern for longer-term shareholder interests.
