BHP Billiton, the world’s biggest miner, has released its revised climate change policy (PDF), ABC reports.

There are four key elements to the plan, which commits $350 million, less than 0.2 percent of BHP Billiton’s net annual profit, to the research and development of clean coal technologies, as well as a strategy for helping staff and customers to change their behaviors.

According to BHP, “The policy includes new targets to reduce the energy and greenhouse intensity of our products by a further 13 percent and 6 percent respectively by 2012. It builds on our previous achievements, which include a 12 percent improvement in our greenhouse intensity over the period 1996 -? 2000.”

The policy is more outward-looking than inward-looking, because it is not necessarily focused on reducing the carbon emissions that come from the company’s mining activities, according to the article.
