Electric vehicles will not be a silver bullet as the ACT looks to cut transport emissions after 2020, the ACT's Environment and Sustainability Commissioner has warned.

Speaking as the ACT government responded to her report on the territory's implementation of climate change reforms, Dr Kate Auty said Canberrans needed to embrace a mix of emission-cutting measures to reduce the risks associated with a warming climate.

Transport will account for 60 per cent of greenhouse gas emissions once the ACT converts to 100 per cent renewable energy in 2020, with passenger vehicles contributing about 75 per cent.

Dr Auty said Canberrans needed to "move away from thinking there's a silver bullet like electric vehicles" and embrace other methods of transport like ride sharing, public transport or cycling.
