Australia’s transport sector must decarbonize quick in an effort to meet emissions reductions in step with limiting world warming to not more than 1.5 levels Celsius. However focusing solely on electrical automobiles (EVs) to get us there may be unlikely to be sufficient.
Transport is Australia’s third-largest and fastest-growing supply of greenhouse fuel emissions. At the moment contributing 21 percent of Australia’s total emissions, it’s projected to turn out to be the sector with the best emissions by the tip 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 expertise enhancements.
The affect of transport is comparable elsewhere, making up a mean of 22 percent of emissions across most of Southeast Asia in 2021. Globally, the sector accounts for 23 % of complete emissions.
As Australian transport emissions proceed to ramp up with journey patterns returning to pre-COVID-19 ranges, now could be the time to search out new methods to realize deep emissions reductions in step with the targets of the Paris Agreement.
Modest Gross sales a Brake
Whereas a lot focus so far has been on the uptake of EVs driving down transport emissions, modest gross sales figures go away Australia susceptible to not assembly emissions discount targets.
New modeling by Climateworks Centre exhibits that zero-emissions automobiles would wish to hit 73 % of recent gentle car gross sales – which means vehicles, vans, SUVs and utes (utility automobiles) – 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 gentle car gross sales.
Taking a technology-only strategy is dangerous as it’s prone to real-world challenges, together with limitations to produce and expertise growth.
To maintain emissions reductions on observe, Australia can diversify the options it’s utilizing to cut back its transport emissions.
This might embody “mode shift” — shifting the way in which we transfer folks and items to extra sustainable modes, similar to swapping a fast drive to the native retailers with strolling or biking there as a substitute — in addition to decreasing pointless journeys, for instance by way of making freight deliveries extra environment friendly.
Such an strategy is a win-win. It could actually decide up the emissions discount slack if Australia’s zero-emissions car uptake is just not fast 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 general can go hand in hand. Options that enhance transport decisions and make journey extra environment friendly and handy additionally scale back emissions.
For instance, if Australia purely focuses on changing each automotive and truck on the street with a zero-emissions possibility, it will get caught with the identical congestion points.
Site visitors remains to be visitors — whatever the car you’re in.
By prioritizing shifting to public and lively transport — like strolling or biking — or decreasing or shortening some journeys, it might scale back complete car journey, serving to make the transport system extra environment friendly.
Climateworks’ latest report suggests {that a} “various options” strategy corresponds to a 27 % lower in car kilometers traveled in 2050, throughout all street automobiles, which might lower congestion and strain on present street infrastructure.
Australia doesn’t need to look far to see different examples of various options being carried out to handle accelerating transport emissions. In New Zealand, Greater Wellington’s transport plan features a goal for rising lively and public transport mode share — which is the proportion of journeys made on foot, by bicycle or scooter, and on public transport — by 40 % by 2030. In Australia, the Victorian state government is taking an identical strategy, setting a goal to extend lively transport mode share to 25 % by 2030.
Australia also can be taught from its northern regional neighbors.
Japan, South Korea and Singapore have every achieved spectacular mode share for lively and public transport of their main cities, making up more than 70 percent of travel in Tokyo, Seoul and Singapore.
Within the instant time period, Australia can scale up present options that keep away from pointless journey and enhance mode shift, making higher use of present infrastructure and companies.
Higher Planning
As an additional advantage, utilizing present transport networks extra effectively reduces the necessity to construct further 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 higher accessibility to public and lively transport.
Planning for extra environment friendly freight actions, together with elevated freight rail connectivity and companies between key freight hubs and ports, helps take vehicles off the street and delivers higher effectivity, productiveness and security advantages to companies and the group.
Growing a reputable plan to cut back Australia’s transport emissions requires a shift in the way in which governments in any respect ranges plan and fund transport.
The federal authorities is at the moment in search of suggestions on its Transport and Infrastructure Net Zero Consultation Roadmap, offering the chance for extra various options to be proposed to decarbonize Australia’s transport sector.
Now we have a chance — proper now — to get this proper. What is obvious is that the extra options which are within the combine, the much less dangerous the street forward can be.
