Frydenberg tells states conservative Liberals won't get their way on emissions cuts

Environment minister says he won't back-end load target as some in his party demand

Josh Frydenberg has told his state and territory counterparts the emissions reduction trajectory in the national energy guarantee will be steady over 10 years, not back-end loaded as some of his conservative party room opponents have demanded.

Frydenberg, the federal energy minister, was clear during a phone hook-up on Friday that Canberra wanted least-cost abatement in the electricity sector, and that meant implementing a linear emissions reduction trajectory between 2020 and 2030, according to sources familiar with the conversation.
