The revival of cookstove research

Daniel Kammen's picture

It may come as a surprise to know that half of the global population uses biomass (wood, agricultural wastes and dung) and coal for cooking.  For Sub-Saharan Africa where electrification rates outside of South Africa are only 28%, biomass and coal are the primary cooking fuels for over three fourths of the population. Combustion of unprocessed biomass fuels, especially in open or poorly ventilated stoves, emits high concentrations of pollutant mixtures – particulates, and carbon dioxide, methane, and carbon monoxide – associated with a number of respiratory and other diseases and is the leading cause of death among infants and children worldwide.

 

Since the task of cooking is mainly done by women and girls, it is they who face daily exposure to levels of pollution which are estimated to be the equivalent of consuming two packets of cigarettes a day (Kammen, 1995; Ezzati and Kammen, 2001).

 

Smoke from domestic fires kills nearly two million people each year, and sickens millions more. This places indoor air pollution as almost as critical a health threat as poor sanitation and AIDS, and a greater threat than malaria. Without systematic changes, household biomass use will result in an estimated 8.1 million Lower Respiratory Infection (LRI) deaths among young children in Sub-Saharan Africa alone, between 2000 and 2030 (Bailis, Ezzati, Kammen, 2007).

 

All of these factors highlight the critical need to evaluate the effectiveness of cookstoves at not only reducing emission, but in impacting health.

What has carbon got to do with kids going to school?

Last week, I headed to Ibi Bateke plateau in the interiors of Democratic Republic Republic of Congo (DRC) to see the country’s first project approved and registered under the Kyoto Protocol.  We set off on a long winding road taking us quickly from Kinshasa to the Ibi plateau – 150 kms away from the daily hustle of the over 9 million inhabitants of Kinshasa. Ibi is characteristically thinly forested, partly a result of the poor porous soils. Despite the vast lands, the majority of the land is uninhabited with villages dotting the landscape.

 

The community is replanting its degraded forests with trees like acacia, pines and eucalyptus that absorb carbon from the atmosphere, allowing the project to generate carbon credits which are purchased by the World Bank’s BioCarbon fund. This project is a trail blazer as some of the revenue from the sale of carbon credits is providing basic health care and schools, offering an integrated vision of development.

 

As we entered the village, we met a group of children walking home. Among them was one older kid who chaperoned the smaller ones - the youngest must have been about five. They chattered enthusiastically about their new school. The school was negotiated as one of the benefits for the participatory management of the plantation. Gautier Tschikaya a resident who was accompanying us told us that one day they were driving around on the plantation and found a whole bunch of kids squatting in an abandoned building so that they would not have to walk the 10+ km every day to get to school. At that point, they built a dormitory for those kids and we visited it - situated just below the school now. 

Your local power source may be responsible for climate change but it gets impacted by it too

Brazil relies heavily on its abundant hydropower resources to meet electricity demand, which is rising by about 5% a year. These resources have helped Brazil hook up more than 2.4 million rural homes since 2003, in addition to delivering electricity to its big cities. But hydropower is vulnerable to drought too, and the Brazilian Amazon—home to most of the country’s hydropower potential—has had two devastating droughts since 2005.

 

That’s just one example of the exposure of the energy sector to climate impacts. Up to now, most of the focus for the discussion of the energy-climate nexus has been on the impact of fossil-fuel energy use on climate change, the need to mitigate it, and the shift to renewable energy sources. This week, two World Bank colleagues of mine have just launched a new study that looks at the issue from the opposite side of the equation: climate impact on energy systems.

 

The study is entitled Climate Impacts on Energy Systems, Key Issues for Energy Sector Adaptation, by Jane Ebinger and Walter Vergara. It provides a framework for further analysis of vulnerability indicators for climate impacts on hydropower, wind, solar, wave and tidal energy. It also offers analytical tools that experts and policymakers can use to construct vulnerability and impact metrics for their energy sectors, along with a review of emerging adaptation practices.

A bond for climate solutions

Why would a group of large investors care about climate change when their primary concern is ensuring adequate returns for their investment portfolio to meet their future financial obligations? This group includes pension funds, insurance companies or foundations. Pension funds alone are estimated to hold over US$25 trillion globally

 

As Alan Miller indicated in his recent blog, a report published by Mercer (a well-known investment advisor) estimates that uncertainty around climate policy could contribute as much as 10% to overall portfolio risk for investors to manage over the next 20 years. So, investors are beginning to pay attention. Choosing to support investments that help address climate change or increase climate-resilience also helps reduce the exposure of portfolios to this risk. 

 

Green bonds issued by the World Bank is one such instrument. Funding raised through green bonds is earmarked for eligible low-carbon and adaptation projects financed by IBRD in its member countries. For example, the money could be used for funding an eco-farming project in China, or improving the solid waste management in Amman, Jordan. On the mitigation side, eligible projects could include solar and wind farms. On the adaptation side, it could be protection against flooding or droughts.

 

Earlier, this month, a 'Green Bond Summit' gathered about 110 representatives of the investment community. The event was hosted by State Street Global Advisers -- an asset manager with over $2 trillion under management in different asset classes. The goal was to discuss how green bonds could attract greater participation from large investors to scale-up financing of climate solutions through the capital markets. The World Bank, a pioneer of the green bond, and other issuers such as ADB, EIB, and IFC deliberated with the participants on prospects for common green bond standards, the financial characteristics investors expect, and the policy issues that underlie the demand for climate investments.  

 

Come to this Malaysian province to see an alternative path on energy

It is all too easy to see environmental protection and economic development simply as competing philosophies, and nothing more. A range of studies attest to the fact that this is a false dichotomy. In my earlier blog, I described the alternative vision that became a reality in a small Nicaraguan coastal community that chose to invest in a diverse set of clean energy alternatives.  Even with cases like this one described in the literature, there remains in some circles a sense that these must be concocted.

 

The headlines often reinforce this simple dichotomy of environment versus economic growth, where the choice presented is “preserve a forest and forego the lumber”, “save a river and deny a community hydropower”, or “find the financing for more expensive solar power or accept ill-health and global warming from coal.” I have been convinced that another path or paths exist, ever since reading a remarkable paper on the `valuation’ of a tropical rain forest (Peters, Gentry and Mendelsohn, `Valuation of an Amazonian Rainforest', Nature). This short paper got me thinking about how we ignore the longer-term economic wins of sustainability for short-term profit.

 

I recently had the wonderful fortune to get involved in a case that reinforced the fact that options always exist, if we work together to find them.

 

Early in 2010, a consortium of citizens from Sabah, Malaysia came to my laboratory at the University of California, Berkeley, convinced that unexplored options must exist to provide the energy needed for this Malaysian Province without placing a 300 MW coal fired power plant on the edge of the ‘coral triangle’ off the coast of North Borneo. This plant was planned at a site only 20 kilometers from the last remaining reserve for the critically endangered Sumatran Rhino of Borneo (of which there may be only 30 individuals or so remaining). This plan would have required the weekly import of coal from South Borneo (Kalimantan). Just a few years ago, the coal plant seemed inevitable.

Is the renewable energy target for India within reach?

Daniel Kammen's picture

Almost 400 million Indians—about a third of the subcontinent’s population—don’t have access to electricity. This power deficit, which includes about 100,000 un-electrified villages, places India’s per capita electricity consumption at just 639 kWh—among the world’s lowest rates.

 

The access gap is complicated by another problem: more than three-quarters of India’s electricity is produced by burning coal and natural gas. With India’s rapidly-growing population— currently 1.1 billion—along with its strong economic growth in recent years, its carbon emissions were over 1.6 billion tons in 2007, among the world’s highest.

 

This is unsustainable, not only from a climate change standpoint, but also because India’s coal reserves are projected to run out in four decades. India already imports about 10% of its coal for electricity generation, and this is expected to reach 16% this year.

 

India’s national and state governments are taking action to correct this vicious circle of power deficits and mounting carbon emissions. The national government has set a target of increasing renewable energy generation by 40 gigawatts (GW) by 2022, up from current capacity of 15 GW, itself a threefold increase since 2005.  Still, renewable sources account for just 3.5% of India’s energy generation at present, so the scale of the challenge is formidable. The cost of meeting it will be high unless the tremendous innovative capacity of India and market reforms can be coordinated to make India a clean energy leader.

The long and winding road to the Green Climate Fund

The UN Climate Talks in December 2010 concluded with a set of decisions known as the Cancun Agreements, which included the establishment of the Green Climate Fund (GCF). Having been involved in many of the negotiating sessions, I know that this fund is seen by many, particularly developing countries as an opportunity to create a ‘legitimate’ institution for delivering scaled-up finance to address climate change. However, there remains significant skepticism on whether or not this Fund could deliver adequate and predictable resources in a timely manner. Much work has yet to be done before the Green Climate Fund could become a reality.

 

Getting organized

In Cancun, the COP decided to set up a Transitional Committee (TransComm) and entrusted it with the task of developing the operational documents for the GCF and making recommendations to the COP in Durban. The Transitional Committee will include representatives from 25 developing countries and 15 developed countries. Some countries have announced their nominations, while others are still in the process of finalizing. The delay comes as no surprise of course. Nominations within regional groups remain a highly contentious and political issue. With limited seats countries are grappling to ensure they have a voice in the body that will design the Fund. I’ve heard the mix of skills and expertise on finance, climate and, development represented in the individuals nominated and they vary from country to country.

Ecosystem services: Seeking to improve human and ecological health together

Daniel Kammen's picture

While attending the CITES (Convention on Trade in Endangered Species) biodiversity summit in Nagoya, Japan, late last year, World Bank President Robert Zoellick said that we must foster development and reduce poverty, and at the same time preserve and improve the planet’s biodiversity and ecological resilience.

 

He noted during a speech at the Cancun COP16 Climate Convention that “empty forests are greatly diminished.” He is completely right, but globally efforts to achieve ecologically sustainable development have been difficult and fraught with failure. Sadly, to some the issue is yet another complication to be ignored or avoided.

 

I spent this weekend at the Mpala Research Center, in Laikipia, central Kenya, which is a remarkable partnership with the National Museums of Kenya, its local partners in Laikipia district, the Smithsonian Institution, and Princeton University in the United States.

 

Mpala is very dear to me. Working more than a decade ago with a remarkable doctoral student of mine who is now a professor, Majid Ezzati, and a fabulous team of local Kenyan medical and energy researchers and extension officers, we completed a detailed “dose-response” study of the health benefits of improved cookstoves. We found that while initial particulate levels were very high–7,000 or more micrograms of particulates per cubic meter (mg/m3)–combinations of improved stoves and clean burning fuels could reduce the incidence of acute respiratory illness by 50%.

Are buildings an important piece of the climate puzzle?

Alan Miller's picture

 

 

They inhabit two different worlds—buildings and climate change—both outside and within the World Bank. It should not be that way as the building sector could be central to both mitigation and adaptation efforts.  

 

Buildings are important for climate mitigation because they account for about 30% of global energy consumption and greenhouse gas emissions. According to the International Energy agency (IEA), energy use in this sector is expected to increase globally about 30 % over the next two decades if recent trends continue; however, the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report concludes buildings offer by far the largest potential source for low cost reductions in CO2 emissions. The World Bank has many projects and analyses addressing this opportunity including a recent ESMAP (Energy Sector Management Assistance Program) report on the benefits and obstacles to effective building codes. These could address over 60 % of building energy use but remain weak and often unenforced in most Bank client countries.

Cities get the call in Cancun

Dan Hoornweg's picture

If you closely read the 20-page draft decision on the Clean Development Mechanism prepared at COP16 in Cancun, you will see a tiny reference to the possibility of including ``city-wide programs’’.Those few words represent an enormous effort: mainly championed by Amman, Jordan, with support from the World Bank, the European Union, UN-HABITAT, C40 Cities, ICLEI, United Cities and Local Government(UCLG) and others.

 

There is reason to be excited. Cities are the every-day face of civilization, the rough and tumble, action oriented arm of government: The ones you call when you need to get things done. And in Cancun they got the call.

 

Making sense of the COP, the ‘Conference of the Parties’ (cities would call it a meeting, ‘fiesta’ if you added beer and a beach) is a full time job. Thousands of people jet across the planet arguing over commas and clauses while climate change waits for true political will. But that political will does not come from countries at a COP. No, first and foremost it needs to be understood, nurtured, and acted-upon in cities. Countries get their marching orders mainly from urban residents, not the other way round.
