So reducing the demand for mechanical cooling is the first step. And then once we get that as low as it can go, we need to meet the remaining demand in a way that’s as climate-friendly as possible. That means paying close attention to electricity and refrigerants, which are the two main sources of emissions.

The electricity emissions come from burning fossil fuels in places where the electricity used by ACs is produced with oil, gas, or coal. Because a lot of electricity is produced this way, ACs are indirectly responsible for a large volume of emissions. That’s why it’s important to use efficient equipment. As we reduce the amount of energy needed to run ACs, we can reduce the amount of fossil fuels burned.

Refrigerants are also really important. They’re classified in terms of their global warming potential, which is extremely high for some refrigerants. One of the most common ones used in air conditioners, R-410A, is 2,000 times more potent than carbon dioxide.

The world is moving away from refrigerants that have high global warming potential, but that transition is not happening as fast as it should. The transition is being driven by commitments many countries made under the Kigali Amendment of the Montreal Protocol to phase down and phase out these refrigerants. But national regulations are needed to speed the process, and in many countries there is no regulation.

Wesseler: OK, so electricity use and refrigerants make ACs problematic from a climate perspective. How problematic, specifically? How much of a climate risk does AC pose?

Carreño: Well, data from CLASP’s appliance efficiency policy model, Mepsy, show that the projected emissions in 2030 from room air conditioners alone—so not counting any other type of space cooling, like fans—are about 800 megatons, which is almost a gigaton. That’s roughly equivalent to driving 186 million gasoline-powered cars for a year.

We’ve also found that, to achieve net zero scenarios by 2050, emissions from the entire appliance sector need to fall by nine gigatons by 2050. So when you consider that room air conditioners will reach one gigaton of emissions in 2030, that tells you the magnitude of the challenge AC poses for the climate community.

What makes this even more difficult is that, at the same time that we need to reduce emissions from AC, we need to help more people get access to air conditioners.

For many years, the efficiency community talked about air conditioners being a luxury—something that was only for households with the capacity to purchase the equipment and pay high electricity bills. But now summers are becoming so hot in many places that it’s almost impossible to stay healthy, to work, to study without AC. But there’s still very low access to air conditioning in Southeast Asia, Latin America, and Africa.

Brazil is a good example. Only 20% of households there own an air conditioner—most people use fans for cooling since they’re cheaper than AC. But the summers are becoming hotter and hotter. This year, the temperature reached 44° Celsius (111° Fahrenheit) in Rio de Janeiro. In heat like that, fans are no longer enough to keep people cool.

Brazil actually set a new record for air conditioner sales in 2024 because of the growing heat. There were six million new ACs sold, which is a 38% increase from 2023.

This same kind of growth is happening in other countries as well. The IEA (International Energy Agency) has forecast that demand for cooling will triple by 2050.

Wesseler: You mentioned that regulations are critical to reducing the climate impact of ACs. What kinds of regulations are most effective?

Carreño: National governments have various policy options. The most popular, and the most effective, are energy efficiency standards. With standards, governments essentially say, “All ACs sold in this country have to operate above this specific level of efficiency.”

Of course, there’s more to it than simply setting the efficiency level. The policy has to be widely communicated to industry—manufacturers, importers, and others—and there have to be mechanisms for testing and certifying products for compliance. But in general, standards are a relatively simple and very effective tool for removing the least-efficient products from the market.

Another important policy is labeling. Labels are a consumer-facing tool; you use them to inform consumers about the different levels of performance of the equipment available on the market. So if you’re interested in purchasing an appliance that uses less energy, that has less impact on the climate, you can easily identify those products using this simple label system.

Some governments also use incentives to promote the purchase of more efficient appliances. Public procurement is a very good incentive. Many governments purchase massive amounts of equipment for official buildings, for municipalities. When policymakers require high efficiency and low climate impact as part of this process, that incentivizes manufacturers and importers to bring in more equipment that meets those criteria. It’s an important lever.

Governments can also provide incentives to help consumers replace obsolete appliances they already own. There are a lot of examples of replacement programs for refrigerators, for instance.

Governments can also support local industry in upgrading appliance production lines. This is something CLASP is looking into in Brazil and India. Brazil produces about 90% of the air conditioners used in the country, and it already has good efficiency standards, but the idea is to support the domestic production of high-efficiency equipment and continue raising the level of ambition. We’re working with the Brazilian Agency for Industrial Development to incorporate energy efficiency into its programs. That’s turning out to be a very, very interesting program.

Wesseler: So it sounds like AC policy can be a win/win for the public and private sectors—it’s not necessarily punitive for manufacturers.

Carreño: Yeah, and this is a really important point. In general, countries’ AC policies are led by countries’ ministries of energy. Reducing energy demand and improving energy security is front and center for these ministries, of course, but they also assess the impacts of these policies on industry and consumers. And that means that policies cannot increase the price of the equipment for consumers or impact local manufacturing. That’s a challenge, because when you improve AC policies, sometimes local manufacturing is going to be impacted. So it’s important to work with local industries so they can continue to be competitive. In some cases, these upgrades can improve their competitiveness in export markets, too.

But this is the main challenge for AC policy in many of these countries. For many years, it’s the reason why policy progress has been slow.

Wesseler: Which countries are doing the most interesting things on AC policy today?

Carreño: China has the current world-leading standard for air conditioners, and the government is looking to go even farther. It’s trying to improve the technology itself, investing in research and development with the goal of doubling the efficiency of cooling equipment. The idea is that when that technology is available, that higher level of efficiency will become the new policy standard. So China is really pushing the envelope.

Brazil is another good example of where policy has really shifted the market to efficient products. For many years, Brazil didn’t revise its AC policies, but this has changed, partly because of efforts by the advocacy community in Brazil. So when the new AC label was published five years ago, followed by a new standard two years later, it really shifted the market to very efficient products.

India is also interesting. The government essentially sets up a schedule that gives manufacturers notice on what efficiency levels they need to reach in future years, helping them understand how policies will change over time. I think that’s a very good practice.

About CLASP’s Industry Accelerator Program in Pakistan

A collaborative initiative between CLASP and SAMA^Verte, the Industry Accelerator is aimed at transforming Pakistan’s electric motor manufacturing sector. Launched in 2023, the program focuses on enhancing the energy efficiency of locally produced electric motors and modernizing production processes. By providing technical assistance, facilitating international knowledge exchange, and supporting the development of energy-efficiency standards, the Industry Accelerator seeks to reduce energy consumption, lower CO₂ emissions, and strengthen the competitiveness of Pakistan’s motor industry.

London and Nairobi 15 September 2025 – An international partnership has launched today to improve consumer choice, affordability and reliability in the solar generator market by driving competition and inspiring innovation.

The collaboration between ZE-Gen, the leading global initiative working to end the use of fossil fuel generators, and CLASP, the international NGO focused on appliance efficiency, will strengthen excellence in a clean technology that can transform communities, economies and the environment by ending the need for fossil fuel generators.

The new partnership will include launching a new international solar-powered generator competition in October to showcase innovation in the market as part of the Global LEAP Awards, which promote the world’s most innovative, high performing and efficient solar solutions in the off-grid sector.

ZE-Gen, together with CLASP, aims to catalyse a shift towards clean, affordable, and reliable energy through solar-powered generators across low-and middle-income countries. The project is part of ZE-Gen’s work to transform the clean energy eco-system across Sub-Saharan Africa, South Asia and the Pacific Islands.

Hundreds of millions of people globally still live without access to electricity. That means no way to cool their homes during hot summers, refrigerate food to keep it fresh, cook without inhaling toxic fumes, or farm without hours of grueling, manual labor.

For decades, the response has focused on expanding energy infrastructure. But power lines alone can’t deliver the full benefits. A village may get connected, but without a fridge, a fan, or a clean cookstove, electricity access remains incomplete.

This is where efficient, affordable appliances come in. They transform energy into opportunity for better health, productivity, and livelihoods. They also improve the economics of grid expansion which makes investment more attractive and sustainable.

To achieve the goal of universal energy access and improve millions of lives, we need to look beyond electricity. Appliances are not a luxury; they are essential energy infrastructure.

Excerpts from this article first appeared in Business Daily Africa in the lead-up to the second Africa Climate Summit in 2025.

By centering climate responses within Africa’s development needs, the continent can unlock new investments, boost incomes, and enhance its resilience. As leaders gather in Addis Ababa for the Africa Climate Summit, the continent must define a bold narrative that strategically links climate action with development progress.

Climate change should not be a global emergency that Africa is simply signing up to solve. This crisis is already costing Africa billions every year, and an estimated 110 million people have been directly affected by climate-related hazards.

Climate action can and must be made to work for Africa by recasting it through an Africa-centered development lens. Responses to the climate crisis offer Africa an opportunity to leverage climate solutions and sustainable technologies to increase incomes, accelerate poverty reduction, and improve adaptation and resilience.

African and global leaders will be converging at the second Africa Climate Summit in Ethiopia from 5 to 10 September. When we gather in Addis Ababa, we must use the Summit as a platform to drive bold reforms and ambitious actions that can repurpose climate change solutions to address Africa’s core development imperatives.

Framing climate action as an opportunity for Africa’s development

Income growth and poverty reduction remain as Africa’s core development pathway, the rising tide that promises improvements across all other social, economic and political indicators.

Africa’s income growth and poverty reduction needs are clear. The average GDP per capita of Sub-Saharan Africa was $1,506 USD in 2024, 40% lower than middle-income countries, and 90% lower than upper upper-middle-income countries. The continent’s GDP grew by 3.3% in 2024. That annual growth rate must increase to approximately 19% on average for GDP per capita to double by 2030. The continent’s GDP must multiply seven times over for African countries to reach middle-income country status.

The pathway to income growth and poverty reduction is equally clear. Africa must increase investments several-fold to drive economic growth, create new jobs, increase productivity, improve competitiveness and enhance social services. Sustained economic growth will result in higher incomes, delivering the poverty reductions that are urgently needed.

Climate change response strategies can be repurposed to meet Africa’s income growth and poverty reduction goals in two ways. First, climate solutions can free up investments, which can then be more productively deployed to drive economic growth. Second, climate solutions can be used to reduce climate vulnerability, improve adaptation, resilience and enable sustained economic growth.

Climate solutions can free up investments for economic growth

Energy efficiency can help secure the emissions reductions that the world needs to achieve to minimize the harshest impacts of the climate emergency. Improving energy efficiency also means lower utility bills for consumers and businesses, and less demand on power grids for governments. The International Energy Agency (IEA) estimates that Africa currently uses 3.7 gigajoules (GJ) of energy for every thousand USD of Gross Domestic Product (GDP). By transitioning to a higher efficiency of 2.7 GJ per thousand USD of GDP by 2030, consistent with IEA’s net zero emissions pathway, Africa could save billions through avoided energy and infrastructure costs. These avoided investments could then be productively deployed for economic and income growth in areas where they are needed.

Climate solutions can reduce climate vulnerability

Climate change is already costing Africa 2-5% of its GDP, the World Meteorological Organization (WMO) estimated. In Sub-Saharan Africa, for example, that translates to approximately $ 40 – $100 billion USD of lost incomes in 2023 – money that could have been utilized to enhance economic growth or support social services.

Africa bears a disproportionately large share of climate impacts because the poor and vulnerable are the least prepared to face climate vulnerabilities when they occur. The WMO projects that by 2030, 118 million extremely poor people in Africa will remain highly vulnerable to climate impacts such as heat stress, droughts and floods.

Energy-efficient appliances, such as lights, fans, air-conditioners, refrigerators, electric cookers, water pumps, cold storages, and milling equipment, are crucial to building adaptive capacity and resilience to climate change among the world’s most vulnerable populations. CLASP estimates that more than half of the population in Africa lacks access to many essential appliances, such as fans and refrigerators. There are equally large ownership gaps for agricultural equipment, such as water pumps, milling equipment and cold storage. These appliances are critical to helping reduce the risks of income and productivity losses from climate impacts.

CLASP estimates that increasing access to seven key appliances across Africa could create a market worth approximately $50 billion USD and catalyse accelerated power infrastructure development to provide electricity for all. It would improve people’s access to essential services, helping individuals manage environmental stressors and economic instability.

Climate change was not Africa’s making, but it is Africa’s fight to shape. If leaders gathering at the Africa Climate Summit in Ethiopia can reframe the response to the climate crisis as an opportunity to accelerate income growth and poverty reduction, then climate action will not only protect the vulnerable but also power the continent’s prosperity. The future is not about choosing between climate action and development; it is about making climate action the very centre of Africa’s development.

CLASP team members joined the Kenya Clean Cooking Week in Kilifi County last week. The team showcased hands-on cooking demonstrations, competitions, and panel discussions, highlighting the role that policy support, financing, partnerships, and grassroots adoption plays in accelerating progress.

Over the past decade, Kenya has made remarkable progress in clean cooking. The share of Kenyans using clean cooking solutions has more than doubled, rising from 15% to 31%, making it the fastest growth rate of clean cooking in Sub-Saharan Africa¹. This momentum has been supported by broader advances in electrification. Electricity access in Kenya grew from 37% in 2013 to 79% in 2023², creating a strong foundation for the wider adoption of clean cooking.

Despite this, around 68.5% of the population still relies on firewood, charcoal, or kerosene; with firewood remaining the main cooking fuel³. These fuels come at a high cost. They degrade forests, pollute the air, and are linked to serious health problems ranging from heart disease and strokes to cancer⁴.

Electric cooking (e-cooking) appliances like induction cooktops and electric pressure cookers offer a safer, cleaner alternative. They eliminate smoke, reduce greenhouse gas emissions, and help curb deforestation by replacing wood and charcoal. They also make kitchens safer by minimizing risks of burns, fires, and explosions, improving the lives of whole communities.

Along with our international and local partners, Ecobora, Gamos East Africa, and MECS, CLASP hosted a cooking competition at our exhibition booth. Contestants prepared dishes of their choice on induction cooktops, using locally available ingredients.

After the cook-off, participants noted things like:

• “The appliances were surprisingly easy to use.”
• “No smoke was produced compared to firewood.”
• “The cooktop felt safe to use and minimized risks like burns.”

The competition showed that clean cooking is not just a climate or health solution, it’s a practical, safe, and efficient choice that improves people’s lives.

With representatives from the Clean Cooking Delivery Unit, GIZ, Kilifi County Government, the Office of the First Lady of Kenya, Practical Action, and UK PACT, CLASP’s Nyamolo Abagi (Director, Clean Energy Access) joined a panel on the importance of partnerships in delivering transformational change across the clean cooking sector. She emphasized that partnerships must extend beyond the usual stakeholders and include the people who use these technologies every day.

In a panel on equity and inclusion, including representatives from Kilifi County Government, Mwangaza Light, Practical Action, SOLCO Partnership, SNV, and WWF, CLASP’s Mike Ofuya (Associate, Clean Energy Access) highlighted the hidden costs of cooking with firewood and charcoal in schools. He noted that shifting to e-cooking appliances can significantly improve health outcomes while freeing up financial and human resources currently consumed by firewood use. These savings could instead fund better food, educational supplies, and infrastructure, while strengthening learning outcomes across the country.

The Government of Kenya aims to achieve universal access to clean cooking by 2028. CLASP is working alongside partners like Ecobora, MECS, and Jikoni Magic to accelerate this goal, by promoting the adoption of affordable, energy-efficient cooking appliances and raising awareness of their benefits.

Clean Cooking Week 2025 sent a clear message. The time for strategizing has passed, it’s time for action that delivers healthier homes, stronger economies, and a safer environment.
