Climate Change

Online Resources for Low-Carbon Energy and Development

Daniel Kammen's picture

An important series of meetings on the Climate Investment Funds, hosted by the African Development Bank, began June 20 in Cape Town, South Africa. At one of the first events, discussion focused on how individual households, communities, cities, companies, and nations find and use tools to develop low-carbon, pro-growth, gender-sensitive, pro-access energy solutions. A key factor in this process is access to:

  • information on technologies and policies
  • tools to build integrated plans for the energy sector at small and large-scale.

At a session on lessons drawn from energy efficiency and renewable energy experiences, I promised to share a preliminary list of websites and online tools to assist local groups and communities gain control of the energy planning process. Here it is:

Low-Carbon Energy and Development Planning Tools

World Bank Low Carbon Development Portal –This comprehensive website provides direct access to a wide range of low-carbon development studies at the community, city, region, national, and global levels, including low-carbon studies (both documents and models) in Brazil and Mexico, rural communities in Nicaragua, as well as Nigeria and Kenya. 

HEAT and TRACE - This portal provides access and documentation for a number of individual models, including:

  • HEAT (Hands-on Energy Adaptation Toolkit),
  • TRACE (Tool for Rapid Assessment of City Energy)

ESMAP (Energy Sector Management Assistance Program) - A general portal for myriad reports and models (including HEAT and TRACE) via the Energy Sector Management Assistance Program at the World Bank Group

HOMER Energy (Hybrid Renewable Energy Optimization Tool) - The HOMER energy modeling software is a powerful tool for designing and analyzing hybrid power systems, which contain a mix of conventional generators, cogeneration, wind turbines, solar photovoltaics, hydropower, batteries, fuel cells, hydropower, biomass and other inputs.  It is used by tens of thousands of people worldwide. For grid-tied or off-grid environments, HOMER helps determine how variable resources such as wind and solar can be integrated optimally into hybrid systems.

Time to clear the smoke

In many parts of the world, a picture of a woman sitting in front of a smoky cookstove preparing a family meal remains an iconic picture of life today. For many families, the three- stone fire or a traditional stove as a cooking device has not changed over centuries.  This need not be the case, and in a growing number of nations, that traditional pattern is changing.

Serious research on improved cookstoves dates back to the 1950s. However, large-scale field programs focused largely on the inefficiency of designs. While the stoves may appear simple, the socio-cultural systems in which they operate, and their impacts on so many aspects of household and regional health and economics, is far from simple. Many approaches have been tried, with some successes and many failures.

Over the last few years, a more complete view of the full human and environmental health impacts of indoor air pollution and the global impact of the fuel and stove cycle has emerged. Poorly managed fuel systems encourage use of unsustainably harvested fuel such as charcoal produced from illegal and ecologically damaging informal production network.

The World Bank is looking at opportunities to improve not only cookstoves themselves, but also the full stove fuel cycle as a way to address energy poverty, human health, and the global greenhouse gas problem. I was delighted to see a new publication that looks at this nexus between health, environment and GHG benefits called Household Cookstoves, Environment, Health, and Climate Change: A New Look at an Old Problem. This report takes stock of existing knowledge on the subject and points out new opportunities by identifying `game-changers’ in the stove technology and fuels.

Trading methane for housing

Three global leaders coming together to deal with climate change was the headline grabbing moment for the recent C40 summit in Sao Paulo (read A tale of three men and 40 cities). Away from the cameras and sound bites was a field trip to Heliopolis, one of Sao Paulo’s biggest slums to drive home the messages that were being discussed in the conference.

As our bus convoy reached the construction site of Heliopolis, we saw round buildings resembling refinery towers. These were brand new apartment buildings for hundreds of Sao Paulo residents who currently live in the Heliopolis slum without proper access to basic services.

And while the round design of the buildings was eye-catching, the real catch is the way this project is being financed: A good portion of the finance comes from carbon finance credits that the city gets through a waste recycling project called Bandeirantes Landfill Gas to Energy Project (BLFGE) in which the methane of biomass waste (which accounts for 60% of Brazilian waste) is converted into energy. This way of generating energy qualifies for carbon credits.

Five ways to boost climate innovation in Ethiopia

Anthony Lambkin's picture

Semi-constructed skyscrapers dotting the horizon, shoppers, commuters and students flooding the sidewalks and a sea of trucks, cars and buses - all fighting for their own space along Bole road, Addis’ main thoroughfare. The signs of a decade of 10% annual economic growth for Ethiopia were evident in the cab ride to the hotel. The energetic vibe of Addis also reminded me that despite rapid advancements, it was still a country with one of the highest poverty rates in the world, large rural populations without energy access, significant bio-diversity and environmental risks and a nascent private sector to deal with it all. 

To engage the private sector was the reason I was in Ethiopia. I was preparing for the business plan development of an Ethiopian Climate Innovation Center (CIC) similar to the Kenyan CIC launching later this year. The $15 million program will invest in and support early-stage companies wanting to become more involved in the booming local and international cleantech markets while becoming profitable and competitive.

However the suite of services developed for each CIC look different in each market and is therefore designed via a rigorous gaps, opportunities and needs analysis with local stakeholders.  While in Ethiopia, I met with a few of the 100-plus stakeholders that will take part in the design phase of the Center. Public and private sectors, development partners, NGOs and academia were eager to share their expertise and experience of what was needed for a CIC in Ethiopia. These are my thoughts following those discussions:

Fast forward to a cooler world

At the C40 Summit in Sao Paolo last week, former President Clinton urged participating cities and the World Bank to make a dramatic reduction in methane and black carbon. He said it would help the earth buy some time on climate change. He has reasons to be worried: In Cancun last year, parties agreed to stabilize average global temperatures at a level not exceeding 2 degree C above pre-industrial levels. This looks difficult as 0.8 degree C warming has already taken place and GHG emissions continue to grow. 

Developed countries collectively reduced greenhouse gas (GHG) emissions by a mere 6.1% from 1990-2008. Compared to the fast track for warming, humanity is on the slow train to reducing carbon dioxide (CO2) emission reductions.

President Clinton’s statement follows two recent reports that point to emerging scientific awareness that a climate change strategy focusing exclusively on carbon dioxide (CO2) is neither the quickest nor the most effective way to achieve long-term climate stabilization. These reports focus on non-CO2 emissions that stay in the atmosphere for a shorter period of time than CO2. As a result, reducing emissions of these non-CO2 gases will result in a slowing of temperature rise over the first half of the 21st century, buying time both to adapt and to transition away from carbon. 

The first report, produced by UNEP and WMO, assesses black carbon and tropospheric ozone. Black carbon—basically soot—is produced by incomplete combustion of carbon fuels, particularly diesel, wood, and coal. It is a dark suspended particle or aerosol, technically not a GHG. It is frequently emitted together with light-colored aerosols (sulfates and organic carbon) which cool the climate. The latest research indicates that, on balance, the warming effect of black carbon overpowers the cooling effect of its companions. It stays in the atmosphere for only a few weeks before falling to earth. Its warming contribution comes from its black color, making it absorb heat while in the air. If it falls onto mountain or polar snow, it accelerates glacial melt.

The state of the carbon markets is Messy - not Messi

Andrew Steer's picture

Last week Barcelona brilliantly beat Manchester United to become the soccer Champions of Europe.  This week Barcelona hosted delegates at Carbon Expo, the annual jamboree for carbon marketers organized by the World Bank and others.  But sadly, the style, strength, efficiency and confidence shown by Messi, Villa, and Pedro are not much in evidence in global carbon markets today. More like my old fourth division club, Bexley United, which I believe has now ceased to exist.

  • There’s certainly a lot to be gloomy about in the world of carbon trading over the past year:
  • The overall size of the market worldwide shrank for the first time ever in 2010
  • The primary CDM market (Clean Development Mechanism) – the principal window of carbon markets to the developing world – fell another 46% to $1.5 billion, down from $7.4 billion in 2005, and the lowest since trading began in 2005.
  • Legislative disappointments in the USA, Australia and Japan, and the market have now become even more concentrated, with well over 90% of trades originating in Europe.
  • Serious irregularities and fraud in the European Trading System (ETS), and suspicions of monkey business in some CDM HFC (Hydrofluorocarbon) transactions.  

Above all, confidence in the post 2012 market, when the first Kyoto Protocol Commitment period comes to an end, is on the floor, and thus demand for post-2012 deliveries is close to zero.

These points are all documented in the Bank’s new State of Carbon Markets Report, 2011 launched this week. And yet 3,000 people turned up at the Carbon Expo this week, and seemed to doing deals and having a good time. Is there anything positive out there? Yes, actually.

First, the overall size of the market was still $142 billion, no small change, although overwhelmingly concentrated within the European Trading System.

A tale of three men and 40 cities

Dan Hoornweg's picture

Driving through Sao Paulo yesterday, I was struck by the power of cities. While cities are part of the climate change problem, they need to be part of the solution too. They are bigger and more energized than any individual or organization. Cities push and cajole; and cities act. Cities are where it all comes together.

Even more so when former President Bill Clinton, World Bank President Robert Zoellick, and New York City Mayor Michael Bloomberg joined forces in Sao Paulo. The accomplished gentlemen born less than a dozen years and 1,500 miles apart spoke and fielded questions with a worldly and gracious informality. The pleasant exchanges sat in contrast to the underlying gravity of their mission. Together they have determined to access their considerable resources to tackle one of the biggest challenges they’ve ever faced: climate change.

The location for the partnership launch is telling. With Mayor Kassab of Sao Paulo hosting this week’s C40 Large Cities Summit everyone reinforced the need for cities to be in this fight. C40 is a group of mayors of major cities of the world responsible for 12% of global emissions. It is not hard to imagine that the battle for sustainable development will be won or lost in our cities.

On behalf of the World Bank, President Zoellick and Mayor Bloomberg, representing the world’s most influential cities as Chair of C40, signed a Partnership MOU outlining how the two organizations will work more closely together and provide focused support to cities. The MOU outlines common tools and metrics, city- tailored finance, and enhanced city-to-city learning.

The `how-to' of renewable energy

Daniel Kammen's picture

Last month, I blogged about the Special Report on Renewable Energy Sources and Climate Change Mitigation of the Intergovernmental Panel on Climate Change (IPCC), for which I was a coordinating lead author. In that report we found that by 2050, roughly 80 percent of global energy demand could be met by tapping renewable sources. The IPCC’s best-case prediction is contingent on a big caveat, however. It is that government policies must “play a crucial role in accelerating the deployment of Renewable Energy (RE) technologies.”

Fair enough, but which policies work best? Which can be replicated widely? Which sectors need more radical new approaches? Given the complexity of energy technologies, and markets, modes of power generation, transmission, distribution, consumption, metering and billing, and the multiplicity of policies—feed-in tariffs, subsidies, ‘feebates’, renewable portfolio standards, and so on— policy makers are often scrambling for guidance.

As author for the Policy and Deployment chapter of the IPCC report, as well as a member of the Summary for Policymakers’ team, I am pleased to suggest a useful source: a recent Discussion Paper No. 22 produced by my World Bank colleague Gabriela Elizondo Azuela, along with Luiz Augusto Barroso, Design and Performance of Policy Instruments to Promote the Development of Renewable Energy: Emerging Experience in Selected Developing Countries.

Elizondo and Barroso studied grid-connected RE policy options used in six countries—Brazil, India, Indonesia, Nicaragua, Sir Lanka and Turkey. They find that sound governance is an essential condition for the success of policy incentives that aim to accelerate the integration of renewable energy. “For example,” Elizondo says, “legal and regulatory frameworks for grid connection and integration have to be in place before RE policy is introduced.” In the IPCC report we called this the ‘enabling environment’.

The infinite win

Flore de Préneuf's picture

A year-long drought has transformed farmers into full-time charcoal burners in the part of Eastern Kenya I visited last week. Delayed rains have also had an impact on farmers in greener parts of the country where land degradation and over-exploited soils are dragging yields down.

But the story that emerges from this man-altered landscape is not all bleak. A range of actors, energized by the food and climate crisis, are taking measures to restore the balance between productive land use and functioning ecosystems, in ways that enhance the resilience of both. 

Kenya's parliament recently requested that farmers put 10% of their farmland under tree cover. Rwanda announced in February a program to reverse the degradation of its soil, water, land and forest resources by 2035. Development partners like the World Bank and the Global Environment Facility have invested millions of dollars in improving the management of ecosystems to protect livelihoods, biodiversity, water access, and other vital services. The World Resources Institute has painstakingly mapped over 450 million hectares of degraded forest landscapes in Africa that could be restored (See map). In fact, the urge to heal the planet's sores has given birth to a booming ecosystem of NGOs, partnerships, social enterprises and research initiatives that build on each others' successes and share a broad vision for positive change.


We know how to triple maize yields using fertilizer trees. We know how to harvest water, slow erosion and store carbon. We even know how to get more milk out of cows by feeding them leaves from trees that stock carbon, provide firewood, fix nitrogen and retain soil moisture – in a changing climate! All the while, those practices help farmers feed their families, attract wildlife, build assets and pay for school fees... 

So why is this kind of "infinite win" work not happening on a more meaningful scale? The organizers of a three-day Investment Forum on Mobilizing Private Investment in Trees and Landscape Restoration in Africa this week in Nairobi are hoping to lift the veil on some of the constraints to sustainable tree-based investment and provoke more synergies between public and private interests.

Biofuels: Threat or opportunity for women?

Daniel Kammen's picture

In Africa, where two-thirds of farmers are women, the potential of biofuels as a low or lower-carbon alternative fuel, with applications at the household energy, community and village level, to a national resource or export commodity, has a critical gender dimension. The key question is: how will increased biofuel production affect women?

To look at the impacts on women, one logical approach is to use a computable general equilibrium model that tracks economic impacts of new crops and how patterns of trade and substitution will change. It’s important to account for the complexities involved, and rely not on a simple, traditional commodity model but one that tracks the impacts on women through changing prices and demands for crops to be sold on local and international markets. Who gains and who loses as prices change, and as the value of specific crops and of land changes?

In a detailed modeling effort based on the situation today in Mozambique, World Bank economist Rui Benfica and colleagues (Arndt, et al., 2011) found that even with significant land area available, the impacts of large increases in bio-fuels production — which are now under way — will do little to benefit women. This is largely because shifts to export-oriented and commercial agriculture, while they may raise export earnings, often exclude women. Women are often already far over-burdened by work and time commitments to subsistence farming, other income-generating activities and household work, including child care. The CGE model shows that financially profitable bio-fuel expansions may widen this gap, and reinforce this exclusion.
