For decades, the energy and environment portfolios have been run by different federal ministers, and they've often been at loggerheads over key elements of national policy. In a surprise move, the Prime Minister's reshuffle yesterday sees the two ministries combined, eliciting mixed reactions, and the former Federal Resources Minister, Josh Frydenberg, given the new top job.

The Climate Institute has long advocated the integration of energy and climate responsibilities under the one ministerial roof, and welcomed yesterday's announcement.
