Australia’s transport sector must decarbonize quick with a view to meet emissions reductions in step with limiting world warming to not more than 1.5 levels Celsius. However focusing solely on electrical autos (EVs) to get us there’s unlikely to be sufficient.
Transport is Australia’s third-largest and fastest-growing supply of greenhouse fuel emissions. Presently contributing 21 % of Australia’s whole emissions, it’s projected to turn out to be the sector with the best emissions by the top of the last decade. As transport emissions proceed to develop, virtually all different sectors’ emissions trended downward from 2023 to 2030 because of present insurance policies that promote switching to renewable vitality and investments in effectivity and know-how enhancements.
The influence of transport is comparable elsewhere, making up a mean of 22 % of emissions throughout most of Southeast Asia in 2021. Globally, the sector accounts for 23 % of whole emissions.
As Australian transport emissions proceed to ramp up with journey patterns returning to pre-COVID-19 ranges, now could be the time to seek out new methods to realize deep emissions reductions in step with the targets of the Paris Settlement.
Modest Gross sales a Brake
Whereas a lot focus thus far has been on the uptake of EVs driving down transport emissions, modest gross sales figures depart Australia susceptible to not assembly emissions discount targets.
New modeling by Climateworks Centre exhibits that zero-emissions autos would want to hit 73 % of recent mild automobile gross sales – which means automobiles, vans, SUVs and utes (utility autos) – by 2030 to maintain transport emissions aligned to limiting warming to 1.5 levels Celsius.
In 2023, they made up simply 7.2 % of recent mild automobile gross sales.
Taking a technology-only strategy is dangerous as it’s inclined to real-world challenges, together with limitations to provide and know-how improvement.
To maintain emissions reductions on observe, Australia can diversify the options it’s utilizing to cut back its transport emissions.
This might embrace “mode shift” — shifting the best way we transfer folks and items to extra sustainable modes, akin to swapping a fast drive to the native retailers with strolling or biking there as a substitute — in addition to lowering pointless journeys, for instance by making freight deliveries extra environment friendly.
Such an strategy is a win-win. It might probably decide up the emissions discount slack if Australia’s zero-emissions automobile uptake shouldn’t be speedy sufficient.
A Vary of Options
But when the uptake accelerates, having a spread of transport options will assist scale back emissions additional for all the sector and Australia extra broadly.
The excellent news is that decarbonizing transport and enhancing the transport system total can go hand in hand. Options that improve transport decisions and make journey extra environment friendly and handy additionally scale back emissions.
For instance, if Australia purely focuses on changing each automobile and truck on the street with a zero-emissions choice, it’ll get caught with the identical congestion points.
Site visitors remains to be site visitors — whatever the automobile you’re in.
By prioritizing shifting to public and energetic transport — like strolling or biking — or lowering or shortening some journeys, it may scale back whole automobile journey, serving to make the transport system extra environment friendly.
Climateworks’ newest report suggests {that a} “various options” strategy corresponds to a 27 % lower in automobile kilometers traveled in 2050, throughout all street autos, which may lower congestion and strain on present street infrastructure.
Australia doesn’t need to look far to see different examples of various options being applied to deal with accelerating transport emissions. In New Zealand, Better Wellington’s transport plan features a goal for growing energetic and public transport mode share — which is the share of journeys made on foot, by bicycle or scooter, and on public transport — by 40 % by 2030. In Australia, the Victorian state authorities is taking the same strategy, setting a goal to extend energetic transport mode share to 25 % by 2030.
Australia can even study from its northern regional neighbors.
Japan, South Korea and Singapore have every achieved spectacular mode share for energetic and public transport of their main cities, making up greater than 70 % of journey in Tokyo, Seoul and Singapore.
Within the quick time period, Australia can scale up present options that keep away from pointless journey and improve mode shift, making higher use of present infrastructure and providers.
Higher Planning
As an additional advantage, utilizing present transport networks extra effectively reduces the necessity to construct extra infrastructure.
In the long run, Australia can extra strategically plan its areas and cities. Finding key locations for dwelling, working, training and recreation nearer collectively and connecting them by way of environment friendly transport networks removes the necessity for lengthy commutes and creates larger accessibility to public and energetic transport.
Planning for extra environment friendly freight actions, together with elevated freight rail connectivity and providers between key freight hubs and ports, helps take vehicles off the street and delivers larger effectivity, productiveness and security advantages to companies and the group.
Creating a reputable plan to cut back Australia’s transport emissions requires a shift in the best way governments in any respect ranges plan and fund transport.
The federal authorities is at the moment searching for suggestions on its Transport and Infrastructure Internet Zero Session Roadmap, offering the chance for extra various options to be proposed to decarbonize Australia’s transport sector.
We have now a chance — proper now — to get this proper. What is evident is that the extra options which are within the combine, the much less dangerous the street forward will likely be.
