Last month, the Intergovernmental Panel on Climate Change drew global attention by providing fresh and overwhelming evidence about the urgency of the climate situation. According to the agency’s latest report, global temperatures will reach 1.5 degrees Celsius above pre-industrial levels within the next 12 years—unless we act now. 
 
Transport bears a huge responsibility in the current situation: the sector contributes to nearly a quarter of global energy-related greenhouse gas emissions, and 18% of all manmade emissions in the global economy.  Under a business-as-usual scenario, this figure will continue rising to reach 1/3 of all emissions by 2040.
 
This means cutting emissions from transport will be central to solving the climate equation. To kickstart this process, the Sustainable Mobility for All initiative (Sum4All) just released a preliminary Global roadmap of action towards sustainable mobility that lays out concrete policy measures for a healthier transport future. Our coalition of 55 leading public and private organizations looks at all dimensions of sustainability: safety, efficiency, equitable access, and, of course, environmental impact.
 
As global leaders head to Poland for the COP24 Climate Conference, now is a good time to identify the most effective solutions for lowering the carbon footprint of transport. In that spirit, we encourage all interested parties to provide input and feedback on SuM4All’s Roadmap of Action: Which policy interventions do you think should be prioritized? Are there any critical measures that are missing from the proposal?  How can the private sector be part of the solution?

Advocating for change: When will transport have its "plastic straw moment?"

In case you haven’t heard, plastic straws are bad news for the planet. This much was made clear over the summer as a surge of anti-straw sentiment spread across many countries. News channels all over the world highlighted how this small and light piece of hollow plastic has been contaminating the oceans and posing a risk to the environment. Outcry was swift and decisive. Practically overnight, countless individuals vowed never to use them again. Even beverage industry giant Starbucks decided to eliminate plastic straws by 2020!  
 
Interestingly, straws make up a fairly small share of the overall plastic pollution in our oceans, especially compared to other sources of plastic waste such as fishing nets and gear. Still, every small piece of plastic that does not end up contaminating the environment is a win. But what’s truly remarkable here is how the global community rallied behind a simple and impactful change, and then followed through with it.
 
The whole campaign about plastic straws and the quick reaction that ensued got me thinking about what a “plastic straw moment” could look like for the transport sector. What small change can we all take to get the world to rally behind transport?

How can Indonesia achieve a more sustainable transport system?

Indonesia, a vast archipelago of more than 17,500 islands, is the fourth most populous country in the world, with 261 million inhabitants, and the largest economy in Southeast Asia, with a nominal Gross Domestic Product of $933 billion.

Central government spending on transport increased by threefold between 2010-2016. This has enabled the country to extend its transport network capacity and improve access to some of the most remote areas across the archipelago.

The country has a road network of about 538,000 km, of which about 47,000 km are national roads, and 1,000 km are expressways. Heavy congestion and low traffic speeds translate into excessively long journey times. In fact, traveling a mere 100 km can take 2.5 to 4 hours. The country relies heavily on waterborne transport and has about 1,500 ports, with most facilities approaching their capacity limits, especially in Eastern Indonesia. Connectivity between ports and land infrastructure is limited or non-existent. The rail network is limited (6,500 km across the islands of Java and Sumatra) and poorly maintained. The country’s 39 international and 191 domestic airports mainly provide passenger services, and many are also reaching their capacity limits.

Technology holds great promise for transport, but…

Not a day goes by without a new story on how technology is redefining what is possible for transport. A futuristic world of self-driving, automated cars seems closer than ever.  While the ongoing wave of innovation certainly opens up a range of exciting new possibilities, I see three enduring challenges that we need to address if we want to make sure technology can indeed help the transport sector move in the right direction:      

The focus is still on car-centric development

The race towards incredibly sophisticated and fully automated cars is well underway: companies like Google, Uber, Delphi Automotive, Bosche, Tesla, Nissan Mercedes-Benz, and Audi have already begun testing self-driving cars in real conditions.  Even those who express concern about the safety and reliability of autonomous vehicles still agree that this innovative technology is the way of the future.

But where is the true disruption? Whether you’re looking at driverless cars, electric vehicles, or car-sharing, all these breakthroughs tend to reinforce a car-centric ecosystem that came out of the industrial revolution over a hundred years ago.

Sustainable Mobility for All: Bringing the vision to life

Making sustainable transport a reality requires a coordinated strategy that reflects the contributions and various interests of stakeholders around the world.
 
The Sustainable Mobility for All partnership has a critical part to play in kickstarting this process. The initiative is working to raise the profile of sustainable mobility in the global development agenda and unite the international community around a vision of transport that is equitable, efficient, safe, and green.
 
The issue of mobility and sustainability resonates well with countries’ concerns. The recent UN Resolution focusing on the role of transport and transit corridors in sustainable development demonstrates the continuing importance attached to the issue of transport and mobility by national governments around the world.

Three reasons why maritime transport must act on climate change

Nancy Vandycke's picture


For years, the transport sector has been looking at solutions to reduce its carbon footprint. A wide range of stakeholders has taken part in the public debate on transport and climate change, yet one mode has remained largely absent from the conversation: maritime transport.

Tackling emissions from the shipping industry is just as critical as it is for other modes of transport. First, international maritime transport accounts for the lion’s share of global freight transport: ships carry around 80% of the volume of all world trade and 70% of its value. In addition, although shipping is considered the most energy-efficient mode of transport, it still uses huge amounts of so-called bunker fuels, a byproduct of crude oil refining that takes a heavy toll on the environment.

Several key global players are now calling on the maritime sector to challenge the status quo and limit its climate impact. From our perspective, we see at least three major reasons that can explain why emissions from maritime transport are becoming a global priority.

In India, this transport engineer is racing toward the future… with German supercars

Are hybrid and electric buses viable just yet?

Hybrid and electric buses may be the future of public transport. But today, they are costlier than their diesel equivalents. Therefore, their implementation requires that private operators be subsidized, or that the higher costs for public operators be covered. For now there are more efficient alternatives for reducing GHG and local emissions.

The most significant emissions reduction will not come from the vehicles; it will come from people leaving their cars at home.

Let’s take the example of a Mexican commuter who chooses whether to ride a bus or drive to work each morning. If she drives, her commute will generate 8kg of CO2, vs. only 1.5kg when riding a diesel bus. By making the greener choice, she is saving up to 6.5kg of CO2. With a hybrid bus, that same ride would emit 1kg of CO2, and zero emission with an electric (assuming zero-emission grid)—translating into additional savings of 0.5kg and 1.5kg over a diesel bus, respectively. The extra savings are welcome, of course, but they pale in comparison to the emissions reduction generated by shifting from a private car to a public bus.

If we analyze a whole system instead of an individual, technology’s potential to reduce emissions gains importance, but is still lower than that of modal shift. That means we first need to focus on providing incentives for drivers to leave their cars behind and turn to public transit. When a bus system with exclusive lanes opens, for instance, 1%-5% of passengers are likely to be new riders who used to drive and made a conscious decision to switch. This proportion can increase to 10-15% with the right ancillary interventions, such as providing non-motorized transport infrastructure, improving accessibility and service quality.

Another great source of emission savings is a more efficient system. We have seen reductions of up to 30% in vehicle-kms after a system reorganization. The following graph compares the potential emission reductions of modal shift and fleet rationalization by shifting vehicles to hybrid (left column) or electric (right column) technology.

Traffic jams, pollution, road crashes: Can technology end the woes of urban transport?

Will technology be the savior of urban mobility?
 
Urbanization and rising incomes have been driving rapid motorization across Asia, Africa, and Latin America. While cities are currently home to 50% of the global population, that proportion is expected to increase to 70% by 2050. At the same time, business-as-usual trends suggest we could see an additional 1 billon cars by 2050, most of which will have to squeeze into the already crowded streets of Indian, Chinese, and African cities.
 
If no action is taken, these cars threaten literally to choke tomorrow’s cities, bringing with them a host of negative consequences that would seriously undermine the overall benefits of urbanization: lowered productivity from constant congestion; local pollution and rising carbon emissions; road traffic deaths and injuries; rising inequity and social division.
 
However, after a century of relatively small incremental progress, disruptive changes in the world of automotive technology could have fundamental implications for sustainability.
 
What are these megatrends, and how can they reshape the future of urban mobility?

Getting a global initiative off the ground: What can transport learn from energy?

Nancy Vandycke's picture

In May last year, key stakeholders joined the World Bank Group in calling for global and more concerted action to address the climate impact of transport while ensuring mobility for everyone. More recently, the Secretary-General’s High-Level Advisory Group on Sustainable Transport noted, in its final recommendations to Ban Ki-Moon, emphasized the need for “coalitions or partnership networks” to “strengthen coherence” for scaling up sustainable transport, as well as establishing monitoring and evaluation frameworks. These issues have been raised at Habitat III, COP22 and at the Global Sustainable Transport Conference in Ashgabat.
 
As the global community readies itself to move from commitments to implementation, what can transport learn from similar initiatives in other sectors, such as Sustainable Energy for All (SE4All)?
