The government's plan to use technology to reduce greenhouse gas emissions will look beyond wind and solar energy to the "next challenges", including hydrogen, carbon capture and storage, and methane produced by livestock.

Energy and Emissions Reduction Minister Angus Taylor says a long-term emissions reduction road map, which will not hand out "massive government subsidies", will be ready by November, in time for the next round of international climate talks.

The government says it won't commit to an emissions reduction target before it can work out the economic cost of the transition, but has not ruled out setting a target to achieve net zero emissions.

The government has criticised the Opposition for its commitment to achieving net zero emissions by 2050. Mr Taylor said in Parliament on Thursday the Opposition had no plan to achieve its emissions reductions, was "making it up as they go along" and risked missing the target or damaging the economy.
