Recently, Indonesia has been combating its most severe forest fire of the decade. Around 43 million Indonesians have been exposed to hazardous fumes, and countless loss of biodiversity and ecosystem services has occurred. An estimated 1 billion tonnes of carbon emission has been released to the atmosphere. Within three months, Indonesia’s daily carbon emission has surpassed the average daily emissions of the whole US economy.

Forest fires in Indonesia are closely related to unsustainable agricultural practices spreading out throughout the country. Indonesia is the world’s largest producer of palm oil, with 8 million hectares of plantation area. Other than its significant contribution to the economy, and broadly debated effects on the environment, oil palm is also regarded as a promising solution to the country’s effort to achieve energy security. The current administration has set ambitious targets to increase national biofuel production, and to consume it domestically.
In this landscape of uncertainty and crisis, scientific support for Indonesian energy policy is more urgently needed than ever. That’s why it is one of our main focuses in the IIASA Tropical Forests Initiative (TFI).
“Scientific authority has to be the basis of our future energy policies,” said Mr. Sudirman Said, Indonesia’s Minister of Energy and Mineral Resources, at the opening session of our first collaborative screening workshop in September in Bandung, Java. In the workshop, jointly organized by IIASA and the ministry, we aimed at laying out a plan to establish a new decision support system for the ministry, based on IIASA’s energy systems models such as the renewable energy systems optimization model, BeWhere and the Model for Energy Supply Strategy Alternatives and their General Environmental Impact (MESSAGE).
Scientific decision support systems (DSS) are a tangible crystallization of bridging science to policy. A decision support system gathers information and analytical expertise in order to improve the quality of policy making, using feedback and evaluation from previous planning and policy implementation. As a practical approach in dealing with what scientists refer as complex adaptive systems, such DSS should be able to integrate visions of long-term planning with technical details that are important for daily executed policies.

Indonesia’s energy sector is a typical example of a highly complex system. Currently, challenges of the sector are more cross-sectoral than ever. Issues that seem to have limited scopes, such as bioenergy, actually influence a broad swath of other areas including agriculture, land use change, air pollution, climate change and social equity.
For that reason, the approach we brought to the recent meeting relies on multiple models. BeWhere brings a snapshot perspective to explore energy supply options that best meet the objective set by policy makers, such as cost efficiency or least CO2 emissions, based on location specific energy demand, resource and infrastructure availability. On the other hand, MESSAGE brings a more macroscopic perspective, looking at various scenarios that project optimal solutions of meeting long-term energy demand in a certain region or country.
To have a truly systems perspective, the above approach cannot stand alone. Before we started looking at Indonesia’s energy sector, we had engaged local researchers in the tropics to localize IIASA’s Gobal Biosphere Management Model (GLOBIOM). GLOBIOM is used to analyze the competition for land use between agriculture, forestry, and bioenergy, which are the main land-based production sectors. Clearly, investigating further into the energy system will allow us to grasp a more holistic understanding and develop solutions to tackle challenges in tropical countries.
As one of IIASA’s pilot countries in the budding TFI, Indonesia represents conflicting realities of the tropics, which are essential to the planet’s well-being. Tropical forests help regulate the Earth’s climate system, while being home to huge biodiversity, millions of plant and animal species. However, the region is also highly challenged by domestic development needs and the growing consequences of a globalized economy. Abundant natural resources and land-intensive agricultural commodities, together with intensified infiltration of global supply chains and complicated socio-economic structures, have resulted in severe ecological pressures that are harmful to the region as well as the planet.
The TFI aspires to address such complexity by applying systems analysis together with regional policymakers. Such application implies a two-fold challenge. The first one is to put together IIASA’s various scientific tools to understand the broader picture that comes out from the integration of interrelated aspects of domestic development. Secondly, working together with policymakers leads to a mutual learning process. Policymakers learn to use scientific models and tools in their decision making process. In this process, fitting the models into the local context is an inevitable step that requires intense communication between scientist and practitioners. Eventually, this process will also benefit researchers by giving them a better understanding of the issue, and opening opportunities for further scientific investigation on new topics.

Q What is sustainable development and why is it important?
A As Brundtland put it, sustainable development meets the needs of the present without compromising the ability of future generations to meet their own needs.
If we do not achieve sustainable development, we will fail to provide even the barest essentials of life—food, water, and shelter—for the growing population. The extra two billion people that will inhabit the world in 2050 can only be accommodated if we are serious about sustainable development.
On a personal level I care about sustainable development because I care about the future, I care about young people, and I care about humanity. Achieving sustainable development is, in my opinion, the single most important issue we face today. Without it, all life on Earth is in jeopardy.
The Global Environment Facility (GEF) was created on the eve of the 1992 Earth Summit in Rio to assist in the protection of the global environment and promote sustainable development. The benefits of such an endeavor have only become clearer over time. It is no coincidence that in 2015 all nations of the world will adopt a set of sustainable development goals which place a strong emphasis on the “global commons,” and that in parallel we have a new global agreement on climate change within reach.
How do you see the world in 2050? What are your most optimistic and pessimistic visions?
I am an optimistic person so I will say that, by 2050, every government, every business, and every individual will take the environment into consideration in all their actions. By 2050, we will all be caring for the Earth, taking responsibility for the use of our planet’s resources, and building economies which will leave no one without dignity or necessary subsistence. We will live within safe planetary boundaries. Pessimism is not an option for me.
How can science help the world achieve sustainable development?
Science plays a critical role. We need it to monitor the state of our resources, the impacts of our activities, and the progress being made. Science can also help identify solutions. It can help encourage businesses to make smart decisions, for example, about saving money though energy efficiency, risk mitigation, and new revenue opportunities driven by innovation and new business models.
Sustainable development is a truly cross-cutting endeavor: it spans many sectors, from agriculture to economics, and transcends national boundaries. Science can play an important role by producing research that is integrated, cross-sectoral and international. In this way, synergies, co-benefits, and trade-offs can be explored in order to identify the smartest paths to achieving multiple sustainable development goals at the same time

How do you see the role of Global Environment Facility in implementing the Sustainable Development Goals?
The GEF is uniquely placed to support the global commons—the planet’s finite environmental resources that provide the stable conditions required for a sustainable, prosperous future for all. Our new strategy—GEF2020—lays out an ambitious vision for the GEF, aimed at addressing the underlying drivers of environmental degradation and delivering integrated, holistic, solutions. We are building on more than 20 years of experience providing support to over 165 countries. By working with national governments, local communities, the private sector, civil society organizations and indigenous peoples, we help find and implement integrated solutions to global challenges.
What are the advantages of a cross-sectoral and cross-border approach to identifying paths to sustainable development?
Many environmental challenges and threats to sustainable development do not respect borders. Moreover, they are often interdependent, or share common drivers. For example, biodiversity loss and climate change is partly driven by unsustainable forest management, which is in turn connected to production of globally traded commodities like palm oil or soy. Problems like this require an integrated, cross-cutting approach.
Given the importance of cross-sectoral interventions, at the GEF we will be implementing a program of integrated approach pilot projects. We believe that these will help countries and the global community in tackling underlying drivers of environmental degradation. I am also very excited about a research program we have recently launched in partnership with IIASA and the United Nations Industrial Development Organization, focusing on development and implementation of integrated solutions to tackle the water-food-energy nexus.

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.
- 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. .
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.

Zero net global greenhouse gas emissions must become a reality before the end of the century if humankind is to stave off the worst effects of climate change. How can this be achieved?
This is a big year for embarking on transformational change towards a sustainable future for planet Earth. Three major global events are taking place, on financing and investments in Addis Ababa, sustainable development in New York and climate mitigation in Paris.
Energy futures are a major challenge on the way forward. In September the UN General Assembly in New York will focus on the Sustainable Development Goals (SDGs), which emphasise an enabling environment and economy for human development.
According to Kandeh Yumkella, Special Representative of the UN Secretary-General for Sustainable Energy for All (SE4All), the proposed SDG 7 on energy (‘Ensure access to affordable, reliable, sustainable and modern energy for all’) is “the golden thread that links poverty eradication, equitable economic growth and a healthy environment”.
SE4All calls for universal access to energy services, doubling the rate of energy intensity improvement and doubling the share of renewable energy, all by 2030. These goals are based on the Global Energy Assessment (GEA), coordinated by the International Institute for Applied Systems Analysis (IIASA) and the result of five years’ work by 500 experts worldwide.

The world is also going to have to introduce a workable, implementable scheme to stave off the possibility of runaway climate change, one with the objective of keeping the average global surface temperature increase to within 2°C over the pre-industrial average. It’s doable, but requires a high level of ambition to achieve immediate and vigorous emissions reductions.
The UN Climate Change Conference in Paris in December 2015 is aiming for – and will hopefully get – a climate agreement based on the 2°C limit that will be legally binding on every nation. To come near to achieving this target will require addressing energy systems, which is central to greenhouse gas emissions mitigation – 80 per cent of global energy is derived from fossil fuels. Limiting emissions will involve a major transformation of energy systems toward full decarbonization.
But we need to move urgently. IIASA research has shown that to meet the 2°C target and avoid dangerous climate change, emissions will need to peak by 2020. By 2050, they will have to be reduced by 30 to 70 per cent compared to today’s levels, and then they will need to go down to zero well before the end of the century.
The reason is that the amount of carbon that can be emitted in the future is limited if we are to restrict climate change to any given level. For example, to meet the 2°C target, humanity has a total carbon budget of some thousand billion tons of carbon dioxide.
This budget needs to be allocated along possible emissions pathways, which explains the need for achieving a peak as soon as possible followed by a decline to zero emissions. Should the emissions peak be late or decline rate too slow, humanity is likely to exceed the cumulative carbon budget. If this occurs, negative emissions would be required: namely, carbon removal from the atmosphere, so that excess emissions are offset rendering stabilization at 2°C possible despite an emissions overshoot.
The question is how could this be done. In stabilization scenarios, the negative emissions are achieved, for instance, by combining combustion of sustainable sources of biomass with carbon capture and storage (CCS). Both technologies are difficult from the current perspective and would require further development and vigorous deployment to reduce the costs and improve their performance.
CCS will presumably be developed anyway to decarbonize fossil fuels in those parts of the world where a transformation toward renewable, and possibly also nuclear, energy is delayed.
So we can decarbonize fossil fuels or switch to a higher percentage of carbon-free energy sources, such as many forms of renewable energy, to reduce and eventually eliminate emissions. What else can we do? GEA findings show that emissions could be reduced by up to half by efficiency improvements in energy, especially in end-use. This means looking at reducing emissions from areas such as transport, buildings, heating and cooling, urbanisation and electric appliances. It means changing mindsets, getting people and policymakers engaged in the emissions-reduction process.
Not all emissions come from sources that are judged to be a sign of development. In many developing countries, cooking over smoky fires burning traditional biomass (or coal) causes small particle pollution that adversely affects the health of women and children. IIASA research is analyzing how to introduce clean modern energy for cooking to millions of people and to cut indoor and outdoor pollution from these sources.
Improving air quality in cities with ground-level ozone, or smog (which results from chemical reactions between polluting compounds in the presence of sunlight), has clear synergies for human health, reducing cardiac, pulmonary and other diseases. It can increase human capital, too. One line of IIASA research shows that implementing a stringent climate policy could reduce globally aggregated lives lost due to indoor and regional air pollution by up to four million.
Sectoral interdependencies with respect to emissions are increasing. For example, reducing carbon and particle emissions to keep climate change in check has enormous implications for the food and water supply. Staggering amounts of water are needed to grow food but are also needed for sustaining energy systems. The productivity of land areas depends on climate and soil conditions. California is entering its fourth year of severe drought, raising concerns for agriculture and wildlife. Unsustainable water use in the state is draining aquifers containing ancient water that will take centuries to replenish.
All water systems – not simply those in traditionally arid or developing areas – are vulnerable to the changing climate. Reducing water use immediately reduces demand for electricity, as well as the fuels required to generate electricity. Water is needed to grow crops for biofuels, but fuel transport costs can be reduced by co-locating biofuel cultivation close to the communities that use them – another IIASA research result. Water can also produce plenty of hydroelectricity. Renewable energy technologies can be utilised to provide heat and electricity needs for water desalination. Water and energy use have almost boundless synergies and have to be analysed from an integrated perspective, which is why at IIASA examining the energy-water nexus is such a priority.
Stringent emission-reduction policies can also help to bolster the energy security goals of individual countries and regions. Such policies promote energy efficiency, the diversification of the energy supply mix and the increased utilisation of domestically available renewable energy sources. The result would be energy systems that are more resilient and simultaneously have a higher degree of sovereignty, especially compared to those so reliant on imports of fossil energy commodities, such as North America, Europe, Japan and, increasingly, China.
The international community has also woken up to the significance of climate-relevant emissions from deforestation and land degradation. The UN’s REDD+ initiative (reducing emissions from deforestation and forest degradation) is one of the more promising areas of agreement in global climate negotiations. Felling a tree always releases carbon, stored over its lifetime in its roots, leaves and branches. Large-scale deforestation therefore is a major contributor to carbon emissions. Nitrogen emissions from agriculture, wastewater management and industrial processes are also produced by human activities and need to be mitigated.

These are complex problems and huge investments are needed to solve the energy challenges society faces today. The ostensibly single aim of reducing emissions will, in fact, require a multiple paradigm shift affecting every domain simultaneously. There are many golden threads, and they are very entangled.
To fund the transformation to sustainable energy services for all, including the three billion ‘left behind’ without access and living at or below the poverty line, the Third International Conference on Financing for Development in Addis Ababa in July will need to dig very deep into its collective pockets. To transform the global energy system, the volume of investment will have to almost double over the next three to five decades, from about $1.3 trillion to some $2.5 trillion.
The money is available. Insurance and pension funds control $50 trillion. Governments can help catalyse other kinds of private investment by providing research and development and early deployment, and by helping to de-risk investment. The cost savings of these climate policy synergies are potentially enormous: $100-600 billion annually by 2030 in reduced pollution control and energy security expenditures (0.1-0.7 % of GDP) could be achieved by combining climate mitigation with combating air pollution rather than pursuing the two goals independently.
For emission reductions to be successful, these practical and financial considerations will need to be supported by a new ethical awareness that will temper our relationship with each other and our planet. Sustainability in every aspect of human life means a shift to equity and inclusion.
With the fast-growing population and the need for universal development, the requirement to control emissions is extremely urgent. The golden thread described by Yumkella with respect to the energy sustainable development goal encompasses the notions of both opportunity and fragility, but it binds us all.

Sunday March 22 2015, was World Water Day. I woke up on that beautiful spring morning in Vienna to the rising sunshine through a slit in the curtains and the lovely humming of birds returning from their winter hideouts some thousands of kilometers away. It was clear to me: winter has ended and spring is here. But there was another thing on my mind that beautiful Sunday morning: the theme of 2014 World Water Day, the water-energy nexus. How can anyone operationalize this concept?
The Water-Energy Nexus has been a hot topic in the water community this year – but how can this concept be turned to action? Poster courtesy UN Water Program
The nexus refers to the notion that global systems are strongly intertwined and heavily interdependent; that systems thinking and planning is required to address persistent global challenges in an integrated way. It is a beautiful concept, no doubt, but what do we do with it?
I joked in my travels and engagements on nexus issues last year that 2014 in my view was the most nexus year. Much has been achieved in 2014: raising awareness of the linkages between water and energy ; demonstrating that integrated approaches and solutions to water-energy issues can achieve greater economic and social impacts; identifying policy formulation and capacity development issues through which the international development community, in particular the UN system can contribute; and identifying key stakeholders and actively engaging them in the discussion on the post-2015 development agenda.
But so far, much of the work on the nexus has been on advocacy, to galvanize interests and mobilize support at the global level. As a result, the concept received widespread global attention and acceptance. The real question now is: How can we transform those commitments and interests into operational frameworks for programs and initiatives? I woke up thinking of three areas:
- Supporting nexus assessment to understand the interactions between various nexus dimensions as countries review and roll out new policies. The objective will be to inspect the performance of current policies in terms of resource use efficiency and productivity in order to facilitate the technical interventions that will be required.
- Strengthening consultations and engagement among relevant sectors for various nexus dimensions. This will help decision makers anticipate, plan, and manage interventions collectively and to re-think policies and strategies to deal effectively with a range of complex interactions that are interlinked and interdependent.
- Reinforcing the enabling environment to facilitate the transitions that are required. This will require action to support key institutions, policy transitions and facilitating public/private funding mechanisms and investment frameworks that are required for nexus interventions.
How do we do this? First, we need to understand the interactions for a given unit of management. It could a country, a river basin, a municipality, a region or sub-region. Then we need to get various spheres of interest engaged in constructive dialogue, both in planning and in resource allocation and utilization. And probably even more importantly we need to provide the institutional, financial, and human capacity requirements to turn ideas into actions.
The challenges are huge in some regions but progress can be achieved with significant multiple gains if we get the assessments right, if we can get key sector actors to continuously talk to each other, and if are able to strengthen the enabling environment to facilitate actions. We need to act before the interest we have generated in the last couple of years diminishes.
