How culture affects perceptions of climate change related technology

By Farid Karimi, independent researcher and IIASA alumnus

There is consensus that the current trend of energy consumption growth and CO2 emissions cannot continue if global warming is to be tackled. Many countries have considered carbon capture and storage (CCS) for addressing climate change. CCS is a technology that mitigates CO2 emissions by removing CO2 from the atmosphere and storing it in carbon sinks–in other words, in an environment or reservoir that has the ability to “store” CO2–such as depleted oil and gas fields.

The Intergovernmental Panel on Climate Change has emphasised that it is not possible to ‘limit likely warming to below 2°C if bioenergy, CCS, and their combination (BECCS) are limited’, while the International Energy Agency has stated that ‘CCS must be part of a ‘strengthened global climate response’. Even if one does not consider the energy sector, CCS is almost the only way to reduce CO2 from the cement and steel industries. Nonetheless, CCS is a controversial technology. There is notable opposition to and different perceptions of the technology among stakeholders and we also know that the reaction of the public to CCS will considerably affect the development of the technology in democratic countries. Therefore, it is important to understand these diverse perceptions and their roots.

In our research, we looked at this controversial technology from a cross-cultural perspective. Previous research has identified general and local mechanisms in how the general public reacts to CCS and researchers have also noticed that there are differences between countries, but the effects of cross-cultural differences had not previously been explored in detail. In our study, which was recently published in the International Journal of Greenhouse Gas Control, we argue that it is crucial to understand how public perceptions of a particular technology emerge and form in their individual contexts or how perceptions are embedded in large-scale cultural frameworks.

Our results show that the effects of individual level variables such as familiarity with technology, or sociodemographic variables such as education, are important, but their effects are likely mediated and confounded by the cultural setting. We found that in parallel with other factors such as trust, cultural dimensions such as uncertainty avoidance and the society’s short-term or long-term orientation affect risk perception. Uncertainty avoidance can be described as the extent to which members of a society feel uncomfortable with uncertain, unknown, ambiguous, or unstructured situations. Long-term orientation on the other hand, refers to a society that fosters virtues and is oriented towards future rewards, in particular perseverance and thrift.

High uncertainty avoidance, for instance, leads to higher risk perception because among nations with a strong uncertainty avoidance index, there is a mentality of “what is different is dangerous”. Moreover, countries that demonstrate a long-term orientation might express a higher level of risk perception concerning the technology because people from these countries place more value on thrift, which implies being more careful about investing in risky or uncertain matters. In addition, investment in real estate is a notable feature of such societies, and this is closely tied to the issue of NIMBY­ – an acronym for the phrase “not in my back yard”, denoting opposition by residents to a proposed development in their area – which is one of the most important controversies related to CCS. For example, Germany has a very high long-term orientation, so Germans have serious concerns about the effect of CCS on the real estate market and about having CCS facilities in their region.

All in all, our work provides a framework to understand why and how societies challenge the technology. Cultural differences and lack of consideration for them have in the past caused the failure of negotiations or implementation of some projects. Our study is a contribution to the field and could be used to understand how cross-cultural differences operate in the realm of sustainable energy technology.

Creativity: a change in thinking for a sustainable future

If fashion is the science of appearances, what can beauty and aesthetics tell us about the way we perceive the world, and how it influences us in turn?

From cognitive science research, we know that aesthetics not only influence superficial appearances, but also the deeper ways we think and experience. So, too, do all kinds of creative thinking create change in the same way: as our perceptions of the world around us changes, the world we create changes with them.

From the merchandizing shelves of H&M and Vero Moda to doctoral research at the Faculty of Information Technology at the University of Jyväskylä, Finland, 2018 YSSP participant Laura Mononen has seen product delivery from all angles. Whether dealing with commercialized goods or intellectual knowledge, Mononen knows that creativity is all about a change in thinking, and changing thinking is all about product delivery.

“During my career in the fashion and clothing industry, I saw the different levels of production when we sent designs to factories, received clothing back, and then persuaded customers to buy them. It was all happening very effectively,” says Mononen.

But Mononen saw potential for product delivery beyond selling people things they don’t need. She wanted to transfer the efficiency of the fashion world in creating changes in thinking to the efforts to build a sustainable world.

“Entrepreneurs make change with products and companies, fashion change trends and sell them. I’m really interested in applying this kind of change to science policy and communication,” says Mononen. “We treat these fields as though they are completely different, but the thing that is common is humans and their thinking and behaving.”

Often, change must happen in our thinking first before we can act. That’s why Mononen is getting her doctorate in cognitive science. Her YSSP project involved heavy analysis of systems theories of creativity to find patterns in the way we think about creativity, which has been constantly changing over time.

In the past, creativity was seen as an ability that was characteristic of only certain very gifted individuals. The research focused on traits and psychological factors. Today, the thinking on creativity has shifted towards a more holistic view, incorporating interactions and relationships between larger systems. Instead of being viewed as a lightning bolt of inspiration, creativity is now seen as more of a gradual process.

New understandings of creativity also call on us to embrace paradoxes and chaos, see ourselves as part of nature rather than separate from it, experience the world through aesthetics, pay careful attention to our perception and how we communicate it, and transmit culture to the next generation.

Perhaps most importantly, Mononen found in her research that the understanding of creativity has changed to be seen as part of a process of self-creation as well as co-creation.

“The way we see creativity also influences ourselves. For example if I ask someone if they are creative, it’s the way they see themselves that influences how creative they are,” says Mononen. “I have found that it’s more crucial to us than I thought, creativity is everywhere and it’s everyday and we are sharing our creativity with others who are using that to do something themselves and so on.”

This means on the one hand that we use our creativity to decide who we are and how we see the world around us for ourselves. But it also means that the outcomes and benefits of creativity are now intended for society as a whole rather than purely for individuals, as it was in the past. It may sound like another paradox, but being able to embrace ambiguity and complexity and take charge of our role in a larger system is important for creating a sustainable future.

“From the IIASA perspective this finding brings hope because the more people see themselves as part of systems of creating things, the more we can encourage sustainable thinking, since nature is a part of the resources we use to create,” says Mononen.

Mononen says a systems understanding of creativity is especially important for people in leadership positions. If a large institution needs new and innovative solutions and technology, but doesn’t have the thinking that values and promotes creativity, then the cooperative, open-minded process of building is stifled.

Working in both the fashion industry and academic research, Mononen has encountered narrow-minded attitudes towards art and science firsthand.

“Communicating your research is very difficult coming from my background, because you don’t know how the other person is interpreting what you say,” says Mononen. “People have different ideas of what fashion and aesthetics are, how important they are and what they do. Additionally, scientific concepts are used differently in different fields.”

“We are often thinking that once we get information out there, then people will understand, but there are much more complex things going on to make change and create influence in settings that combine several different fields.” says Mononen.

For Mononen, the biggest lesson is that creativity can enhance the efforts of science towards a sustainable world simply by encouraging us to be aware of our own thinking, how it differs from that of others, and how it affects all of us.

“When you become more aware of your ways of thinking, you become more effective at communicating,” says Mononen. “It’s not always that way and it’s very challenging, but that’s what the research on creativity from a systems perspective is saying.”

Insights into the future of agriculture from past human climate change responses

While living in Cairo in 2010, I witnessed first-hand the human toll of political and environmental disasters that washed over Africa at the end of the last century. Unprecedented numbers of migrants were pressing into North Africa, many pushed out of their homelands by conflict and state-failure, pulled towards safer, richer, less fragile places like Europe. Throughout Sub-Saharan Africa, climate change was driving up competition for scarce land and water, and raising pressure on farmers to maintain the quantity and quality of their crops.

It is a similar story throughout the developing world, where many farmers do without the use of expensive chemical fertilizer and pesticides, complex irrigation, or boutique seed varieties. They rely instead on traditional land management practices that developed over long periods with consistent, predictable conditions. It is difficult to predict how dryland farmers will respond to climate change; so it is challenging to plan for various social, economic, and political problems expected to develop under, or be exacerbated by, climate change. Will it spur innovation or, as has been argued for the Syrian civil war[1], set up conflict? A major stumbling block is that the dynamics of human social behavior are so difficult to model.

Instead of attempting to predict farmers’ responses to climate change by modelling human behavior, we can look to the responses to environmental changes of farmers from the past as analogues for many subsistence farmers of the future. Methods to fill in historical gaps, and reconstruct the prehistoric record, are valuable because they expand the set of observed cases of societal-scale responses to environmental change. For instance, some 2000 years ago, an expansive maize-growing cultural complex, the Ancestral Puebloans (APs), was well established in the arid American Southwest. By AD 1000, members of this AP complex produced unique and innovative material culture including the famed “Great Houses”, the largest built structures in the United States until the 19th century. However, between AD 1150 and 1350, there was a profound demographic transformation throughout the Southwest linked to climate change. We now know that many APs migrated elsewhere. As a PhD student at the University of California, Los Angeles, I wondered whether a shift to cooler, more variable conditions of the “Little Ice Age” (LIA, roughly AD 1300 to 1850) was linked to the production of their staple crop, maize.

I came to IIASA as a YSSP in 2016 to collaborate with crop modelers on this question, and our work has just been published in the journal Quaternary International.[2] I brought with me high-resolution data from a state-of-the-art climate model to drive the crop simulations, and AP site information collected by archaeologists. Because AP maize was quite different from modern corn, I worked with IIASA soil scientist Juraj Balkovič to modify the crop simulator with parameters derived from heirloom varieties still grown by indigenous peoples in the Southwest. I and IIASA economic geographer Tamás Krisztin developed a statistical technique to analyze the dynamical relationship between AP site occupation and simulated yield outcomes.

We found that for the most climate-stressed high-elevation sites, abandonments were most associated with increased year-to-year yield variability; and for the least stressed low-elevation and well-watered sites, abandonment was more likely due to endogenous stressors, such as soil degradation and population pressure. Crucially, we found that across all regions, populations peaked during periods of the most stable year-to-year crop yields, even though these were also relatively warm and dry periods. In short, we found that AP maize farmers adapted well to gradually rising temperatures and drought, during the MCA, but failed to adapt to increased climate variability after ~AD 1150, during the LIA. Because increased variability is one of the near certainties for dryland farming zones under global warming, the AP experience offers a cautionary example of the limits of low-technology adaptation to climate change, a business-as-usual direction for many sub-Saharan dryland farmers.

This is a lesson from the past that policymakers might take note of.

Impressions and messages from the Vienna Energy Forum and the R20 Austrian World Summit 2018

By Beatriz Mayor, Research Scholar at IIASA

On 14 and 15 May, Vienna hosted two important events within the frame of the world energy and climate change agendas: the Vienna Energy Forum and the R20 Austrian World Summit. Since I had the pleasure and privilege to attend both, I would like to share some insights and relevant messages I took home with me.

To begin with, ‘renewable energy’ was the buzzword of the moment. Renewable energy is not only the future, it is the present. Recently, 20-year solar PV contracts were signed for US$0.02/kWh. However, renewable energy is not only about mitigating the effects of climate change, but also about turning the planet into a world we (humans from all regions, regardless of the local conditions) want to live in. It is not only about producing energy, about reaching a number of KWh equivalent to the expected demand–renewables are about providing a service to communities, meeting their needs, and improving their ways of life. It does not consist only of taking a solar LED lamp to a remote rural house in India or Africa. It is about first understanding the problem and then seeking the right solution. Such a light will be of no use if a mother has to spend the whole day walking 10 km to find water at the closest spring or well, and come back by sunset to work on her loom, only to find that the lamp has run out of battery. Why? Because her son had to take it to school to light his way back home.

This is where the concept of ‘nexus’ entered the room, and I have to say that more than once it was brought up by IIASA Deputy Director General Nebojsa Nakicenovic. A nexus approach means adopting an integrated approach and understanding both the problems and the solutions, the cross and rebound effects, and the synergies; and it is on the latter that we should focus our efforts to maximize the effect with minimal effort. Looking at the nexus involves addressing the interdependencies between the water, energy, and food sectors, but also expanding the reach to other critical dimensions such as health, poverty, education, and gender. Overall, this means pursuing the Sustainable Development Goals (SDGs).

Another key word that was repeatedly mentioned was finance. The question was how to raise and mobilize funds for the implementation of the required solutions and initiatives. The answer: blended funding and private funding mobilization. This means combining different funding sources, including crowd funding and citizen-social funding initiatives, and engaging the private sector by reducing the risk for investors. A wonderful example was presented by the city of Vienna, where a solar power plant was completely funded (and thus owned) by Viennese citizens through the purchase of shares.

This connects with the last message: the importance of a bottom-up approach and the critical role of those at the local level. Speakers and panelists gave several examples of successful initiatives in Mali, India, Vienna, and California. Most of the debates focused on how to search for solutions and facilitate access to funding and implementation in the Global South. However, two things became clear­. Firstly, massive political and investment efforts are required in emerging countries to set up the infrastructural and social environment (including capacity building) to achieve the SDGs. Secondly, the effort and cost of dismantling a well-rooted technological and infrastructural system once put in place, such as fossil fuel-based power networks in the case of developed countries, are also huge. Hence, the importance of emerging economies going directly for sustainable solutions, which will pay off in the future in all possible aspects. HRH Princess Abze Djigma from Burkina Faso emphasized that this is already happening in Africa. Progress is being made at a critical rate, triggered by local initiatives that will displace the age of huge, donor-funded, top-down projects, to give way to bottom-up, collaborative co-funding and co-development.

Overall, if I had to pick just one message among the information overload I faced over these two days, it would be the statement by a young fellow in the audience from African Champions: “Africa is not underdeveloped, it is waiting and watching not to repeat the mistakes made by the rest of the world.” We should keep this message in mind.

Emission reductions from fuel subsidy removal – the researchers respond to the debate

By Jessica Jewell, David McCollum, Johannes Emmerling, Christoph Bertram, David E.H.J. Gernaat, Volker Krey, Leonidas Paroussos, Loïc Berger, Kostas Fragkiadakis, Ilkka Keppo, Nawfal Saadi, Massimo Tavoni, Detlef van Vuuren, Vadim Vinichenko, Keywan Riahi

Our recent paper about our research on the effects of removing fossil fuel subsidies, published in Nature on February 8, 2018, generated a lot of comment and debate.

Here, we respond to three important themes raised in these comments. The first concerns the interpretation of our findings about the significance of subsidy removal for reducing CO2 emissions, the second concerns our approach to modeling and the data we used, and the third relates to policy options for more effective subsidy reform.

What are fossil fuel subsidies and why are they interesting for climate?

Fossil fuel subsidies are government interventions which decrease the price of fossil fuels below the market price. They can go to supporting the extraction of oil, gas, and coal (production subsidies) or making fuels cheaper for consumers (consumption subsidies) and amounted to over US$400 billion in 2015. There is a certain irony in that so many governments signed on to the Paris Agreement in 2015 yet in that same year many of those same governments spent so much money making fossil fuels cheaper.

How much would removing these subsidies help climate change mitigation efforts? How does it compare to what countries have already pledged to do for the climate under the Paris Agreement?

Comparing emission reductions from subsidy removal to key climate targets

Some commenters claim that it is already known that the effect of removing fossil fuel subsidies on emissions is limited. However, according to the authoritative Intergovernmental Panel on Climate Change Fifth Assessment Report (IPCC AR5), subsidy reform “can achieve significant emission reductions”. This view also is evident in the political sphere as: the Friends of Fossil Fuel Subsidy Reform, a group of countries called fossil fuel subsidy reform “the missing piece of the puzzle in the fight against climate change”.

Our findings are that fossil fuel subsidy removal would lead to a 1-4% reduction in CO2 emissions in the energy sector by 2030 if oil prices stay low, and 1-5% if oil prices rise again, compared to the rise in emissions if subsidies are maintained, the baseline. It means that subsidy reform is a modest contribution to the global reductions required to achieve 2°C in a least-cost pathway, 27-57% by 2030.

More importantly, in our paper we compare emission reductions from subsidy removal not to this ideal goal, but to the actual targets pledged in the context of the Paris Agreement. Globally, Paris pledges would reduce emissions against the baseline in the energy sector by 9-13% in 2030 (under a moderate growth baseline) which is a larger reduction than fossil fuel subsidy removal would deliver. Under both the Paris climate pledges and fossil fuel subsidy phase-out global emissions would continue to rise whereas to achieve the 2°C target they should peak and eventually decline.

Identifying the regions with greatest impact

This global assessment is only part of our study. In addition, we show how the impacts of subsidy removal are different by region. In the major oil and gas exporting regions (Middle East and North Africa, Russia and its neighboring countries, and Latin America), removing fossil fuel subsidies lowers emissions by the same amount or more than these countries’ Paris pledges. Government revenues in these regions largely come from energy exports, which are squeezed by today’s low oil prices. Lowering government spending by removing subsidies is a real political opportunity to reduce emissions in these regions.

In other developing and emerging economies (India, China, the rest of Asia and Sub-Saharan Africa), removing fossil fuel subsidies has less of an effect on emissions than these countries’ Paris pledges. In addition, the number of people who might be affected by subsidy removal in these regions is higher, simply because there are many more people living below the poverty line, for whom subsidies make the most difference. Taken together, these two findings frame one of our main results: that subsidy removal would be most useful for the climate precisely in the regions where it would affect fewer people living below the poverty line.

Data on subsidies

The second theme we would like to address relates to our data and modeling. Some commenters claimed that we underestimate both production subsidies and the effect of their removal.

According to data from the IEA and OECD only about 4% of subsidies are production subsidies. The International Institute for Sustainable Development (IISD) and Overseas Development Institute (ODI) publish an independent estimate based on their own definition and approach. Extrapolating to the global level, production subsidies would be about 14% in 2013 under their approach. We ran a sensitivity analysis using this higher production subsidies estimate. This did not change our findings (discussed in the Supplementary Information to our article).

Some commenters claimed that our study does not consider electricity production subsidies. This is also not true. We use the IEA data where power generation subsidies are captured in electricity subsidies. The SI discusses how each model integrates electricity subsidies.

There are other, fragmented estimates for electricity generation subsidies in individual countries, which generally take a different view of subsidies. For example, the recent report from IISD on Chinese subsidies to coal-fired power plants indicates that in 2014 and 2015, between 89% and 97% of these subsidies went to incentivize air pollution control equipment or closing inefficient plants. According to the same report, these subsidies also dropped by half from 2014 to 2015. Few governments would consider this as an environmentally-harmful subsidy, and removing such support will increase, not decrease emissions.

For our main analysis, we relied on IEA and OECD data for both production and consumption subsidies because these inventories are aligned with governments’ own estimates which are prepared as part of the G20 pledge to remove subsidies from 2009 reaffirmed in 2016. By using the same input data as governments and international organizations who are pledging or considering fossil fuel subsidy removal, we ensure the policy relevance of our results for these actors. 

Estimating the effects of production subsidy removal

There were several comparisons of our results with those reported in a recent paper by Erickson et.al. in Nature Energy, which found that under the currently low oil prices, removing production subsidies in the US would make several oil fields unprofitable and eventually result in their closure. We find contrasting these two papers misleading as they ask very different research questions. Our study does not investigate how many oil fields in the US or elsewhere will become unprofitable after subsidy removal, but looks at the global effect of subsidy removal on emissions by taking into account trade in fossil fuels, the demand response and potential substitution of fuels and technologies. Erickson and his colleagues do not ask how much emissions will change as a result of closed oil fields. These are two very different questions.

Erickson and his colleagues compare the amount of carbon embedded in the oil reserves that may become unprofitable due to subsidy removal, to how much carbon the US would be allowed to emit under a stringent climate target. This creates an impression that they investigate the impact of removing oil production subsidies on US emissions. However, calculating the emission impact from removing oil production subsidies requires not only calculating the emissions embedded in foregone oil production, but also the possible emissions resulting from replacing this lost oil with other fuels, or changes in demand, for example if Americans choose to drive less if wells are closed, or if the US imports oil instead. We use these types of feedbacks in our models to calculate the emissions effects of subsidy removal (both consumption and production).

Redirecting subsidy funds

The third theme raised in the comments to our article was why we did not model redirecting subsidies to supporting renewable energy. While this is a very tempting question to ask from a climate perspective, and certainly one which we could do in our models, we did not consider it a realistic policy to be prioritized in our scenarios. In most countries fuel subsidies were introduced to support those on low incomes, although it is an inefficient way to do so. A state budget deficit and today’s low oil prices can often prompt successful subsidy reform. Indonesia for example recently expanded spending on infrastructure and programs to reduce poverty, while India introduced vouchers for cooking fuels. Iran, meanwhile introduced universal health coverage.

Fossil fuel subsidies do need reform

We would like to express our agreement with two comments, one from Ian Parry who wrote a commentary to our paper in Nature, and another from David Victor in his statement to Scientific American, that there are many reasons to reform fossil fuel subsidies other than emissions reductions. Our article does not cover these reasons and should not be interpreted as a comprehensive assessment of all aspects of subsidy removal.

We do however hope that our transparent and rigorous assessment of the effects of subsidy removal on CO2 emissions and energy use will support realistic and effective subsidy removal policies, and help in understanding the relative importance of a range of emission-reduction measures needed for achieving the ambitious long-term targets of the Paris Agreement.

As some commenters pointed out, we need all tools in the box to combat the enormous challenge of climate change. We fully agree. At the same time, we also believe in the need to understand how much each tool can do and where it can be most effective. This is exactly what our study answers.
