<p>When it comes to road transport, Australia is at risk of becoming a climate villain as we lag behind international best practice on fuel efficiency.</p>
<p>Road transport is one of the main sources of greenhouse gas emissions and <a href="http://ageis.climatechange.gov.au/">represented</a> 16% of Australia’s total carbon dioxide emissions in 2000, growing to 21% in 2016. Total CO₂ emissions from road transport increased by almost 30% in the period 2000-16.</p>
<p>Fuel efficiency (CO₂ emission) standards have been adopted in around <a href="https://www.infrastructure.gov.au/vehicles/environment/forum/files/Vehicle_Fuel_Efficiency_RIS.pdf">80% of the global light vehicle market</a> to cap the growth of transport emissions. This includes the United States, the European Union, Canada, Japan, China, South Korea and India – but not Australia.</p>
