The world’s biggest mining company urged world leaders on Thursday to seek a deal setting an international price on carbon, warning that unilateral action could lead to the imposition of trade barriers in the future.
The call was made by BHP Billiton as Australia came under fire for restricting talks on climate change at a G20 leaders’ summit in Brisbane this weekend, which will aim to boost global growth amid fears over the health of the eurozone economy.
Andrew Mackenzie, BHP chief executive, said a deal between China and the US limiting greenhouse gas emissions offered a glimmer of hope for the type of global climate deal that could avoid “messy and imprecise” unilateral action.
