Meanwhile, the market looked to BHP Australian annual general meeting yesterday, where the mining giant's commitment to climate change dominated shareholder questions.
When the first four questions chairman Jac Nasser received were on climate change, it became clear the issue would be the hot topic at the Perth meeting.
Nasser said BHP had first started thinking about climate change two decades ago.
"So what you're asking us to do, in essence, we started doing 20 years ago," he told shareholders.
He went as far as saying BHP was a "dream" company to invest in against the backdrop of climate change.
"This company is well positioned for a company no one can define."
Nasser said he was frustrated by the fact that the company had the "foresight" to think about climate change so long ago but was coming under such scrutiny.
