Climate summit held by business and green groups to end six-year policy war

Exclusive: mirroring the Turnbull government's tax debate with all options 'on the table', six different climate policies are canvassed at closed-door summit

Leaders from business, welfare, the conservation movement, the electricity sector and the union movement have moved to try to fill Australia's climate policy vacuum by starting a new slogan-free debate to help political parties find workable greenhouse policies.

Mirroring the Turnbull government's tax debate, in which all policy options are back "on the table", the groups commissioned major consultancies to present on six climate policy options at a special closed-door summit this week. They intend to publish the results in a back-to-the-drawing-board policy "primer" to be released next year.
