Sustainable mobility: can the world speak with one voice?

Nancy Vandycke's picture

 
The transport sector is changing at breakneck speed.
 
By 2030, global passenger traffic is set to rise by 50%, and freight volume by 70%. By 2050, we will have twice as many vehicles on the road, with most of the increase coming from emerging markets, where steady economic expansion is creating new lifestyle expectations and mobility aspirations. Mega-projects like China’s One Belt, One Road could connect more than half of the world’s population, and roughly a quarter of the goods that move around the globe by land and sea.
 
These transformations create a unique opportunity to improve the lives and livelihoods of billions of people by facilitating access to jobs, markets, and essential services such as healthcare or education.
 
But the growth of the transport sector could also come at the cost of higher fossil fuel use and greenhouse gas emissions, increasing air and noise pollution, a growing number of road fatalities, and worsening inequities in access.
 
Although these are, of course, global challenges, developing countries are disproportionately affected.
 
The vast majority of the one billion people who still don’t have access to an all-weather road live in the developing world. Although low and middle-income countries are home to only 54% of the world’s vehicles, they account for 90% of the 1.25 million road deaths occurring every year. If we don’t take action now, transport emissions from emerging markets could triple by 2050, and would make up 75% of the global total.
 
While the case for sustainable mobility is evident, the sector still lacks coherence and clear objectives. There is a way forward, but it requires pro-active cooperation between all stakeholders.
 
That’s what motivated the creation of Sustainable Mobility for All (SuM4All), a partnership between a wide range of global actors determined to speak with one voice and steer mobility in the right direction.
 
SuM4All partners include Multilateral Development Banks, United Nations Agencies, bilateral organizations, non-governmental organizations, civil society organizations, and is open to other important entities such as national governments and private companies. Together, these organizations can pool their capacity and experience to orient policymaking, turn ideas into action, and mobilize financing.

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)?

From taxi apps to car sharing, from buses to the metro, from bike sharing to walking, not to mention personal cars, there are more transportation choices than ever before for that staple of modern life: the daily commute. The same goes for the transport of goods, which can get from A to B by road, air, rail, waterways and soon drones. There are currently more than 12,600 km (nearly 8000 miles) of metro or urban rail and 5,400 km (3,300 miles) of bus rapid transit (BRT), collectively providing 154 million trips a day in 250 cities. Increased access to transport and enhanced connectivity decreases travel time and generates higher rates of direct employment, keys to elevating overall economic opportunity. 

That’s the good news. The bad news is that the increase in mobility options comes at a high price. The challenges associated with growing traffic, especially in cities, are significant and threaten to become insurmountable. And despite the wide range of ways to get around, there have never been so many people who lack access to transportation or the means to use transportation.

Follow the moving carbon: A strategy to mitigate emissions from transport

Transport currently accounts for 23% of energy-related carbon emissions--equivalent to 7.3 gigatons of CO2 globally in 2013—and, unfortunately, ranks among the fastest growing sources of such emissions.

If we’re serious about bucking the trend and reducing the environmental footprint of the sector, we first need to understand where transport emissions come from, and how they will evolve. If you take out the 1 GT of CO2 emissions released by the aviation and maritime industry for international transport, about 6 GT of transport emissions are classified as “domestically generated.” Today, the share of domestically generated emissions is split pretty much evenly between developed and developing countries: high-income OECD countries account for about 3 GT, while non-OECD countries are responsible for another 3 GT.

However, under a business-as-usual scenario, this breakdown is expected to change dramatically. Without bold action to make transport greener, emissions from emerging markets are poised to grow threefold by 2050, and would then make some 75% of the global total. Domestically generated emissions from OECD countries, in comparison, should rise by a more modest 17%.

The share of each mode in overall transport emissions also differs depending on which part of the world you’re looking at: while 2/3 of emissions in OECD countries are from cars, freight and particularly trucking is currently more important in the context of emerging markets.  Trucks actually generate over 40% of transport emissions in China, India Latin America and Africa.

Climate-smart transport is a key piece of the sustainable development puzzle

When it comes to climate change, the transport sector is both a victim and a perpetrator. On the one hand, transport infrastructure is particularly vulnerable to the effects of climate change such as higher temperatures, increased precipitations, and flooding. At the same time, transport is responsible for 23% of energy-related greenhouse gas (GHG) emissions, and is one of the sectors where emissions are rising the fastest. This statistic alone makes it pretty clear that there will be no significant progress on climate action without greener, more sustainable mobility.

Yet, before COP21, the transport sector was conspicuously absent from climate talks. The strong, structured presence we saw last year in Paris and this year in Marrakech is finally commensurate with the urgency needed to address the transport-related issues on the climate agenda.

The rising importance of transport in the global conversation is reflected in major commitments like the Sustainable Development Goals (SDGs) and the Paris Agreement. As an example, over 70% of the Nationally Determined Contributions (NDCs) that countries have proposed to implement the Paris Agreement include transport commitments, ranging from increasing public transport in cities to shifting freight from roads to railways and waterways.

Visiting Ecuador’s very first metro

It’s easy for me to take public transport for granted: a mere 5 minutes’ walk from my office at the World Bank Headquarters, I have access to 2 metro stations served by 4 different lines that offer easy connections to many parts of the Washington DC area. There is a sense of comfort in knowing that, despite the occasional hiccups that we all love to complain about, metro provides a safe and reliable way for me to commute to work every day.
 
In Quito, Ecuador, many people don’t have that luxury. Granted, there is the notable Bus Rapid Transit (BRT) that operates high-frequency services on dedicated lanes and has significantly reduced travel time. But the system is already crowded, and has exceeded its capacity: during peak hours, each bus carries an average 175 passengers, well above the 165 maximum capacity leading to overcrowding due to a huge flow of passengers.
 
According to 2010 figures, Ecuadorians owned 71 vehicles per 1,000 inhabitants, significantly higher than countries like Bolivia, Nicaragua, Egypt, and Angola, which were respectively at 68, 57, 45, and 31 vehicles per 1,000 inhabitants. In 2010, the government introduced Road Space Rationing, a plan that aims to reduce traffic by limiting the number of vehicles on the road within a certain area based on license plate numbers. These are great initiatives, but more is needed in view of how fast Quito is growing.

First-ever Global Conference on Sustainable Transport: What is at stake?

Nancy Vandycke's picture

On November 26, 2016, UN Secretary-General Ban-Ki Moon will convene the first-ever Global Conference on Sustainable Transport, in Ashgabat, Turkmenistan. What is at stake in this capstone two-day event? What fresh developments might it yield, and how might it change the dynamics for transport?
 
The new transport agenda. A number of earlier high-level events—including the UN Climate Action Summit, the OECD/International Transport Forum, and the Habitat III Conference—helped give a long-needed boost to the visibility of transport in the international arena in 2016. The events also helped position transport within the current set of global commitments that include the Sustainable Development Goals, the Paris climate agreement, the Decade of Action on Road Safety, and the Habitat III New Urban Agenda. The forthcoming Ashgabat event will put front and center one simple notion: for the next 15 years, the transport agenda will be framed by that set of global commitments. The commitments define the space within which governments, international organizations, the private sector, and civil society will have to act on transport. And they will dictate the future size and direction of transport funding.
 
This is a paradigm shift. Previously, the transport agenda was defined by the goal of providing access to transport infrastructure. Under the new framework, the international community has committed itself to much more. First, the issue is no longer simply access but equitable access for all. Second, other, equally important objectives have been added, including the efficiency and reliability of mobility services, transport safety, and decarbonization. In sum, the internationally accepted transport agenda concerns more than economic and social development; it is also about being part of the climate change solution.

Who needs cars? Smart mobility can make cities sustainable

Pierre Guislain's picture
 

Last year marked an important tipping point: for the first time, half of the global population lives in cities. Cities currently add 1.4 million people each week and this population growth comes with new buildings, roads and transport systems.

In fact, 75 percent of the infrastructure that will be in place by 2050 does not exist today. With cities poised to invest now in infrastructure that will last for decades, huge opportunities lie ahead. But without major shifts now in how we manage established as well as rapidly growing cities, we risk losing out on the potential of urbanization to create more inclusive and prosperous societies.

2015 offers a big chance for the international community to help put cities on a more sustainable path. We at the World Bank and the World Resources Institute (WRI) believe that we must seize this opportunity, because cities and urban mobility are key to a sustainable future.

Business-as-usual urbanization patterns come at a hefty price. Cities already produce 70 percent of energy-related greenhouse gas emissions and traffic crashes claim 1.2 million lives per year, with developing cities carrying the greatest burden.

Traffic congestion cost Rio de Janeiro and São Paulo a combined $43 billion in 2013 alone, equivalent to 8 percent of each city’s GDP. In Beijing, the costs of congestion and air pollution are estimated at 7-15 percent of GDP. Urban sprawl costs the United States alone $400 billion per year.

This is not the future we want for our cities.
