Earlier this week, Volkswagen admitted fraudulent software causing high exhaust emissions of nitrogen oxides (NOx) from several of its diesel car models during normal driving. That diesel cars emit many times more NOx in normal driving than their legal limit has been known for more than a decade in Europe. The surprise to me is that the enforcement of these legal limits is pursued now from the USA and not from a European authority, and that – in the face of a public outcry – the automaker admitted the same software was not only in US models.

Following this announcement, I took a second look into the on-road emission data from Europe and compared it with data collected by colleagues in the USA. We find that VW diesel cars in Europe emit as much NOx as the incriminated models in the USA, as shown in the chart for VW Golf, Jetta and Passat models model years 2009 to 2013.

We measured significant differences between manufacturers, yet on the whole the gap between officially certified and real-driving NOx emissions from diesel cars in Europe has been growing. The few models with low emissions are by far outnumbered by cars with high NOx emissions. Yet, VW’s emission levels are not even the worst in class.

10 steps to removing carbon from the global economy

By Nebojsa Nakicenovic, Deputy Director General, International Institute for Applied Systems Analysis (IIASA), Austria (Originally published on the World Economic Forum Agenda Blog.)

Goal 7 of the Sustainable Development Goals is ambitious: Ensure access to affordable, reliable, sustainable and modern energy for all. This must be accomplished without compromising Goal 13: climate. This is achievable.

In spite of ups-and-downs and outright shocks in the global economy, some quite recent, the economic success stories of the industrialized countries are role models for the countries that are still developing. This puts the entire global community in the dichotomous position of needing to fire up the engine of growth, without producing the greenhouse gases it has been emitting since the beginning of the Industrial Revolution. What is the answer?

Very few questions in the complex area of energy and climate change can have a simplistic answer, but I am going to attempt one here: decarbonization, namely, drastic reduction of carbon dioxide and other greenhouse gas emissions per unit of economic activity.

Back in 1993, I wrote this:

“The possibility of less carbon-intensive and even carbon-free energy as major sources of energy during the next century is consistent with the long-term dynamic transformation and structural change of the energy system.”

My view in 2015 is the same; however, the scientific community 22 years later has a much better understanding of “the decarbonization challenge” and how it can be addressed. I will sketch out a 10-step approach to the removal of carbon from the global economy, but first I’d like to paint in a bit of the background.

Carbon dioxide is the main greenhouse gas and contributor to climate change. The largest source is our use of fossil fuels to drive development. Carbon dioxide emissions have increased exponentially since 1850 at about 2% per year, while decarbonization of the global economy is only around 0.3% per year.

The 2012 Global Energy Assessment, in which IIASA played a leading role, puts the current decarbonization rate at approximately six times too low to offset the increase in global energy use of about 2% per year. To meet the goal of the 2009 climate agreement (the Copenhagen Accord), namely, “the scientific view that the increase in global temperature should be below 2 degrees Celsius” to prevent dangerous anthropogenic interference with the climate system, global net emissions of carbon dioxide and other greenhouse gases will need to approach zero by the second half of this century, implying deep, deep decarbonization rates.

But we need deep decarbonization while energy needs are increasing to meet the demand of the developing world, including the three billion without access today to sustainable energy. All scenarios in the academic literature that lead to further economic development in the world, universal access to sustainable energy, and the stabilization of climate change to less than 2 degrees Celsius, anticipate deep and urgent decarbonization. Here’s my 10-point plan for doing that.

  1. Change attitudes
    Attitudes to energy use are based on many factors, from cultural norms to overall infrastructure design. We need much greater political will to affect a change in attitudes: it is critical that policy interventions should communicate to citizens the ethical notion of improved well-being and health now and for future generations of a zero-carbon economy. .
  1. Transform governance
    The transformation needed this century is more fundamental than previous transformations, like the replacement of coal by oil, because of the significantly shorter time needed to achieve it. Thus, government policies are essential, and are needed particularly in changing buildings codes, fuel efficiency standards for transportation, mandates for the introduction of renewables, and carbon pricing.
  1. Improve energy efficiency
    More efficient provision of energy services, or doing more with less, and radical improvements in energy efficiency, especially in end use, will reduce the amount of primary energy required and represents a cost-effective, near-term option for reducing carbon dioxide emissions, as well as having multiple benefits in different areas of life.
  1. Ramp up renewable use
    We can show that the share of renewable non-fossil energy from solar, wind, rain, tides, waves, and geothermal sources in global primary energy could increase from the current 17% to between 30% and 75%. In some regions it could exceed 90% by 2050, provided that public attitudes change and efficiency increases.
  1. Reduce global energy intensity
    The energy intensity in the industrial sector in different countries is steadily declining due to improvements in energy efficiency and a change in the structure of the industrial output. Far greater reductions are feasible by combining these improvements with adoption of the best-achievable technology.
  1. Use known technologies
    Carbon dioxide capture and storage (CCS), now being piloted, is a pathway that leads to decarbonization with continued use of fossil energy. It requires: reducing costs, supporting scale-up, assuring carbon storage integrity and environmental capability, and securing approval of storage sites. Nuclear energy could make a significant contribution in some parts of the world, or it could be phased out as, for instance, in Germany.
  1. Improve buildings
    Retrofitting buildings can reduce heating and cooling energy requirements by 50–90%; new buildings can be designed and built using close to zero energy for heating and cooling. Passive energy houses and those that produce energy onsite are another great opportunity to achieve vigorous decarbonization. In conjunction with compatible lifestyles oriented toward rational energy use, efficient buildings are an important decarbonization option.
  1. Cut transport carbon
    A major transformation of transportation is possible over the next 30–40 years and will require improving vehicle designs, infrastructure, fuels and behavior. Electrically powered transportation reduces final energy use by more than a factor of three over gasoline-powered vehicles. A shift toward collective mobility is an essential option. This also implies behavioral changes and new business models like car-sharing, and self-driving cars to replace individual mobility.
  1. Clean industrial processes
    Overall, global industry efficiency is only 30%. Improved energy efficiency in industry results in significant energy productivity gains and, in turn, improved productivity boosts employment and corporate competitiveness. A shift toward low to zero emission energy sources in industry is another important and much-needed change. For example, with an aggressive renewables strategy, near-zero growth in GHG emissions in the industrial sector would be possible. Finally, decarbonization would also involve changes of industrial processes, for example, from high to low temperatures.
  1. Stranded assets and ‘derisking’ renewables.
    The flow of investment needs to be changed away from fossil fuels and toward efficiency, renewables, decarbonization of fossil energy sources, and especially efficient end-use in buildings, transport, and industry. Sustainable energy futures require relatively high up-front investments with the benefit of low long-term costs. They are attractive in the long run, but the up-front investments need derisking and other forms of support, such as feed-in tariffs.

A new vision of Trans-Eurasian transportation

By Katherine Leitzell, IIASA Science Writer and Press Officer

The Trans-Siberian Railway is the longest railway in the world, connecting Moscow with Vladivostok and the Sea of Japan. Built at the turn of the 19th century, the railroad network connected remote Eastern Russia with the rest of the country, and created the first overland link between Europe and Asia.

In a meeting last week at IIASA, Russian researcher Yury Gromyko presented an equally ambitious transportation “megaproject” for the next century: the Trans-Eurasian Belt of Razvitie (Development in Russian), or the TEBR. The project, led by a group of leading Russian intellectual centers, would provide a new transportation network between markets in Europe and Asia, including high-speed rail, roads, as well as infrastructure such as pipelines and telecommunications networks.

Yet in Gromyko’s view the TEBR is also a development project that would bring new opportunities for trade and employment to the entire corridor of the construction. Gromyko described the project as a “New Future Zone,” which could revolutionize trade and economic development across Eurasia.

If the TEBR succeeds, Gromyko envisions new networks of smart cities in eastern Russia based on innovative technologies and new industries that would stem the tide of migration towards Moscow, instead pulling a new generation eastwards. “We need millions of young people to move to the Russian Far East. To attract them, there would need to be exciting jobs and affordable housing,” said Gromyko.

Gromyko presented the project at a workshop entitled, Development of Transport and Infrastructure in Eurasia. The meeting brought together transportation experts from across Eurasia to discuss visions for future development of the continent, and the key role of a multi-infrastructure approach in that development. Multi-infrastructure presupposes integration of different infrastructures from transportation to energy and telecommunications.

“Transportation and infrastructure are simply integral to economic development,” explains Michael Emerson, a senior researcher in the project who splits his time between the Centre for European Policy Studies (CEPS) and IIASA. “You cannot have one without the other.”

The event was the 5th in a series of scoping workshops arranged as part of the IIASA-coordinated project, Challenges and Opportunities of Economic Integration within a wider European and Eurasian Space, following previous workshops focused on research methodology, trade policy, non-tariff barriers, and energy. In addition to transportation and infrastructure projects, participants discussed investment and finance options for such major international efforts, as well as the challenges and opportunities of drawing private investment for long-term investments in infrastructure.

Several more scoping workshops are planned on different dimensions related to economic regional integration, explained project leader Elena Rovenskaya, the director of IIASA’s Advanced Systems Analysis Program. They create the foundation for the research phase involving researchers, business leaders, and policymakers from across Eurasia.

Interview: Can nature bounce back?

Jesse Ausubel is director of the Rockefeller University Program for the Human Environment. He was a participant in one of the first classes of IIASA’s Young Scientists Summer Program (YSSP).

Please tell us about your current job – what is your major area of focus?
I do research and manage research.  My research primarily concerns sparing natural resources through changes in technology and consumer behavior.  The main projects I help manage are the Deep Carbon Observatory  (concerned with the origins of life and hydrocarbons) and the International Quiet Ocean Experiment (aiming to achieve a better soundscape of the oceans, including human additions of noise).

In your recent paper, Nature Rebounds, you present a hopeful view of environmental change which contrasts with many other views of the future. What makes you think your view is possible?
The paper looks objectively at the peaking of demand for many natural resources that has occurred in the USA and elsewhere since about 1990.  Demand for water, energy, land, and minerals is softening, while demand for information continues to soar.  Fortunately, information brings precision in production and consumption and spares other resources.  The result is, for example, huge regrowth of forests.  The global greening, or net growth of the terrestrial biosphere, allows re-wilding.  Ecological restoration inspires many people, although learning again to live in proximity to bears and wolves is not simple.

What would be the key changes humanity would need to make for this vision to come true at a global scale?
Most of what happens is not because humanity consciously and deliberately strategizes and makes changes.  The role of policy is vastly exaggerated.  French intellectual Bertrand de Jouvenel wrote in his profound 1945 book, Du Pouvoir, “politics is the last repository of hope. “ High tech tycoons Steve Jobs (Apple) and Jeff Bezos (Amazon) popularized tablets and e-readers and did more, together with the innovators in e-mail, to spare forests than all the forest activists and UN targets.  Good systems analysts find high leverage for sound directions like decoupling and recycling. Simply observing well, describing the world as it is, matters greatly and demands tremendous skill and dedication.

Please tell us about your YSSP work at IIASA? What were your questions, and what did you find?
I participated in the 1979 YSSP, the second class.  IIASA’s energy group had developed scenarios of how human activities might change climate. My task was to explore impacts of climate and adaptations.  The 1980 book Climatic Constraints and Human Activities summarizes much of what we learned. Most of the book still reads well.  Following climate today, I am reminded of the remark, “Everything has been said, but not everyone has had a chance to say it.”

How did the YSSP influence your career?
My YSSP summer encouraged a big drop in my disciplinary and national prejudices. My chief, Soviet hydrodynamicist Oleg Vasiliev, had great intellectual integrity.  We had a wonderful rapport and in fact in July I sent him best wishes for his 90th birthday.  Oleg invited me to stay in Laxenburg for two more years, which opened more avenues, most importantly collaborations with Cesare Marchetti, Nebojsa Nakicenovic, and Arnulf Gruebler which continue today. The YSSP class itself was lively and talented; John Birge, for example, has had a great career in operations research.  Finally, IIASA showed me the value of scientific cooperation between nations in conflict, and I have actively supported such cooperation ever since.

Science for policy’s sake

By Daisy Brickhill, IIASA Science Writer and Editor

“In some senses, the science-policy process can be likened to a sausage being made,” said Dr E. William Colglazier in his lecture at IIASA this week. We could take this in different ways: that it is messy, perhaps, or that things get churned around or made to fit. But the most important parallel must surely be that if it is done right it can bring huge benefits. In this case not for your taste buds, but for humanity.

It’s a messy business, but it’s surely worth it if we get it right: comparing the science-into-policy process with the art of sausage making.

If anyone knows what the science-policy process is like, it is Colglazier. Soon after completing his PhD in theoretical physics in 1971 he became a fellow of the American Association for Advancement of Science, providing advice for policymakers. He has been at the forefront of the science-policy interface ever since, and is perhaps best known for his role as the Science and Technology Adviser to the US Secretary of State from 2011 to 2014.

During his lecture Colglazier explored how scientists can best advise policymakers. “There’s an old joke: if a policymaker asks a scientist what time it is, the scientist will tell him how to build a watch.” To avoid this, Colglazier says, scientists need a fundamental understanding of both the needs and time frames of policy making.

The best way to achieve this is to engage. A scientific advisor is not a distant voice, hovering between knowledge and policy. Scientists must not be afraid to get involved; it is only through lots of interaction with policymakers that they will begin to understand what is needed. “Scientific advising,” says Colglazier, “is a contact sport.”

For their part, policymakers do not always understand the scientific process. To prevent this causing misunderstandings, scientists must be clear about the uncertainties in the science, and what it can and cannot say. They must explain exactly how the evidence leads to the recommendations they have given.

Colglazier also emphasized the importance of communication, something I silently cheered for, as a science writer often hoping to reach policymakers. “Telling a good story with persuasive anecdotes is often more influential than a dry, hundred-page report,” he said, and I couldn’t agree more. I have seen articles about accurate, rigorous, and important science drift by unnoticed where others, based on a more trivial studies, spark debate and engagement. The difference is often that those in the former category are three pages longer, full of impenetrable jargon, and bury their juicy conclusions at the bottom.

Sometimes, scientists are asked to advise on issues that go beyond science, straying into value judgements. For example, when assessing an environmental risk a scientist can give the numbers and the uncertainties and information on the consequences. But they cannot provide a definitive answer to the question that the policymaker is really asking: how safe is safe enough?

Does that mean scientists should steer clear of this territory entirely? No, says Colglazier. “Feel free to give advice when you are asked, but be honest about what the science can say.” The important thing is to remember that scientists have no special expertise when dealing with value judgements.

Ultimately, the science-into-policy process is a messy one. Scientists find it difficult to grind up the prime fillet steak of their data into the mincemeat needed for policy making. But the importance of this step should not be underestimated. Science and policy must work together if we are to achieve a sustainable future for humanity.
