Washington DC, 11 March, 2024 – CLASP’s latest report, “How National Appliance and Equipment Energy Conservation Standards Can Improve Public Health and Advance Justice40 Initiative Goals,” finds that standards adopted over the past 30 years have led to substantial reductions in fine particulate matter (PM2.5) and PM2.5 precursor emissions, which are harmful pollutants that can cause respiratory and cardiovascular health issues such as asthma, lung cancer, or heart disease. Data from 2017 suggest that this reduction could prevent between 1,900 and 4,400 PM2.5-related deaths every year. Using the value of statistical life, this translates to monetary benefits of $18 to $41 billion.

Importantly, CLASP’s study finds that the benefits of these standards are distributed relatively equitably among communities with those designated as disadvantaged by Justice40, an initiative aiming to ensure that 40% of the overall benefit of federal climate investments go to disadvantaged communities, receiving a significant share.

These findings demonstrate the far-reaching positive impacts of standards and highlight the importance of the US Department of Energy meeting its deadlines for updating approximately 50 appliance efficiency standards, including for water heaters, by January 2025. Finalizing all pending standards could avert 2.5 billion metric tons of greenhouse gas emissions while saving consumers nearly $1 trillion over 30 years, according to the agency.

The report outlines actionable recommendations to amplify the benefits of standards and suggests ways to measure their contribution towards Justice40 goals. By implementing these recommendations, policymakers, industry stakeholders, and communities can work together to ensure that national appliance standards continue to drive positive change for all people and the planet.

Appliances Supporting Life-Saving Health Facilities

The Rhino Camp is a refugee settlement camp in Northern Uganda. Within the camp is the Ofua Health Center 3, a solar-powered medical facility with just two doctors attending to a population of over 45,000 people. Dr. Gideon Anguerini highlights a pressing challenge: the center’s reliance on a single, energy-inefficient fridge unsuitable for solar power. The health center aims to purchase an efficient solar-powered fridge from POPO Africa, an appliance distributor based in Uganda. With the fridge, the health center’s services will be expanded, its energy costs significantly lowered and it can treat more patients.

Delivering Change through Solar Solutions

From the outset, POPO Africa’s vision aimed at enhancing maternal health by ensuring that clinics in refugee camps had reliable solar lighting powered by solar battery packs. This expanded, as the company moved into leasing the battery packs to the wider community.

POPO’s solar batteries are a lifeline for community businesses, enabling them to operate after dark, offer phone charging services, and more. With 54 distribution points across five districts, POPO’s impact is widespread, directly employing 75 people and indirectly supporting many more through their distribution network. POPO Africa also places a strong emphasis on women’s economic empowerment, boasting a workforce that is 70% female.

Recognizing the critical need for cooling services POPO aimed to revolutionize the off-grid cold chain service in Northern Uganda. The only barrier to this was capital constraints. POPO could not pursue the cold chain opportunity without external support. With funding from CLASP’s Productive Use Financing Facility, POPO was able to start selling solar-powered refrigerators, that will benefit healthcare facilities and empower local businesses.

Transformative, Impactful Financing

Efficient productive-use appliances (PUAs) like solar-powered refrigerators, pumps, and milling machines can have transformative effects on local communities, small businesses, and the environment. However, despite their potential for income generation, PUA sales remain remarkably low in emerging markets due to their relatively high upfront costs and a lack of access to finance. CLASP set up the Productive Use Financing Facility to address these challenges by helping distribution companies like POPO Africa sell their products at lower prices.

Overcoming Capital Constraints

With CLASP’s Facility’s procurement subsidies and capacity-building grant, POPO is working to sell approximately 140 refrigerators within a year. They have made that transformative step into the cold chain market and are now extending affordable, off-grid cooling to their customers, like the Ofua Health Center.

With each solar-powered battery and refrigerator, POPO is helping to build a future where energy is accessible, businesses thrive, and healthcare advances, even in the most remote corners of the world.

About The Productive Use Financing Facility

CLASP’s Productive Use Financing Facility, is supported by The Global Energy Alliance for People and Planet (GEAPP). It has provided financing to 24 companies in six countries, to enable the distribution of over 13,000 productive-use appliances, directly impacting more than 58,000 households.

In our daily lives, an often-overlooked activity may be impacting our health more than we realize. When we burn gas in our homes, we’re not just preparing meals; we’re cooking up a cocktail of pollutants. These pollutants pose health risks, particularly for vulnerable individuals and those with pre-existing conditions like asthma, according to environmental health expert Frank Kelly, a professor at Imperial College London. Transitioning from gas to electric hobs and ovens can eliminate the health risks associated with gas combustion, Kelly said.

The field study

In 2023, CLASP, in collaboration with TNO and Opinium, carried out the largest indoor air quality study focused on gas cooking ever conducted in Europe to understand the extent of the problem. Researchers provided air quality sensors to 250 households across 7 European countries. Over two weeks, the sensors measured and recorded levels of nitrogen dioxide (NO₂), carbon dioxide, and particulate matter emitted in kitchens.

In kitchens equipped with gas stoves, researchers found that levels of NO₂ often exceed the World Health Organization’s (WHO) air quality guidelines and outdoor air pollution limits in the European Union (EU) and the United Kingdom (UK). The study’s findings demonstrate the necessity to improve air quality in our homes, along with a critical need to inform people about the health risks associated with gas cooking and transition to cleaner cooking alternatives.

The hidden cost of cooking with gas

The repercussions extend beyond health; they’re also impacting our wallets. Each year, indoor air pollution related to gas cooking is estimated to cost the European Union around €3.5 billion and the UK government approximately £1.4 billion. These costs include lost earnings, decreased productivity, increased healthcare expenses, and missed educational opportunities.

A recipe for change

Professor Frank Kelly emphasizes that, given the wealth of information linking gas use to health issues and climate impact, “the use of gas is now outdated.” There is a pressing need for change. The most significant decrease in indoor concentrations of NO₂ can be accomplished by making the switch from gas to electric cooking appliances. Accelerating the transition to electric cooking is identified by experts as the most effective solution, alongside raising awareness about the need for adequate ventilation.

To safeguard public health, action is required. Governments, industry leaders, healthcare providers, researchers, and individuals all have a role to play in reducing indoor air pollution related to gas cooking:

• Government: Policymakers across the EU and UK can help accelerate the transition to electric cooking by strengthening appliance standards and establishing energy labels for hobs that inform consumers about pollution levels.
• Industry: Manufacturers and retailers should privilege the production of electric cooking appliances, make the most efficient products more affordable, and discontinue the production of gas hobs and ovens.
• Civil society and healthcare: Advocates should raise awareness of the health risks associated with the use of gas cooking appliances.
• Research: By conducting further studies and fostering innovation, researchers can contribute valuable insights to guide policy decisions and technological advancements.
• On an individual level, adopting cleaner electric hobs and ovens is recommended to limit exposure to NO₂. Ventilating kitchens during and after cooking is a simple, practical step toward mitigating the health risks associated with the use of gas hobs and ovens.

Our culinary choices carry significant health, economic, and environmental weight. Let’s make informed choices to protect our health and contribute to a cleaner future.

CLASP is working with governments to ensure they consider frameworks and incentives that encourage a transition away from gas cooking to electric alternatives.

Every day at lunchtime, dozens of hungry customers find their way to Chez Clémance, a small restaurant in Kigali, Rwanda. In the back of the shop, owner Muhimpundu Clémance and chef Nsengiyumva Célestin would traditionally have prepared their most popular dishes — meat, rice, beans, and yams — over charcoal fires.

But while their delicious food keeps patrons happy, this cooking method generates air pollution, damaging the environment and posing a health risk for staff. What’s more, the flames present a fire hazard.

Testing clean cooking solutions

Electric pressure cookers offer many benefits over cooking on charcoal. Durable, safe, and affordable, they lessen exposure to harmful air pollutants, lowering cooking costs while reducing deforestation and the burning of fossil fuels.

To understand how these appliances would perform in a busy commercial kitchen, CLASP and Sustainable Energy for All (SEforALL) selected Chez Clémance to field-test two electric pressure cookers over a period of four months. CLASP’s team set up the cookers, along with monitors designed to measure their efficiency. The researchers are also surveying the business owners to understand whether these appliances are a good fit for their needs.

Measuring efficiency and business viability

While laboratory testing gives a glimpse of appliance performance in a controlled environment, it provides only a limited representation of how products operate under the rigors of real use. Field-testing like that underway at Chez Clémance is critical to measure the appliance’s efficiency over a set time. It can quantify time savings and additional income generated or saved, as well as calculate avoided CO2.

These measurements are particularly important in newly developing appliance markets where there may not be a history of appliance usage or community exposure to how appliances can impact the livelihoods of first-time users.

About the project

This project is part of the Productive Use of Energy Pilot Study in Rwanda, conducted by CLASP with the support of Sustainable Energy for All (SEforALL) and the World Bank. The appliances being tested are electric pressure cookers, electric bikes, solar water pumps, and solar powered fridges.

CLASP works enhance the access to affordable, energy-efficient appliances to improve the lives of people and reduce the impact on our climate.

Federal energy efficiency standards for appliances and equipment lead to cleaner air, creating health benefits. By conserving energy, standards reduce both indirect emissions (from power plants) and direct emissions (from fossil fuel appliances). This decreases human exposure to fine particulate matter (PM2.5) pollution, a harmful form of particle pollution capable of entering the lungs and bloodstream and contributing to increased incidences of respiratory and cardiovascular health complications.

This factsheet summarizes the key findings from a recent report that estimates the distribution of public health benefits in disadvantaged communities in the United States. Specifically, it estimates the reductions in PM2.5-related deaths that can be attributed to standards adopted over a 30-year period and explores how standards can contribute to Justice40 Initiative goals.

Efficient appliances, lighting, and equipment are critical climate solutions, situated at the nexus of mitigation, adaptation, and sustainable development.

However, not enough is being done to maximize their benefits. In this report, CLASP lays out actions that must be taken by 2030 to put the world on a pathway to net zero emissions and enable a just energy transition. Our research identifies the ten appliances most vital to meeting global climate mitigation targets and improving people’s lives: the Net Zero Heroes.

Brussels, Belgium – Cooking on gas regularly fills kitchens with air pollution above recommended levels, the largest-ever home monitoring study in Europe has found.

The World Health Organization (WHO) daily limit value for nitrogen dioxide (NO₂) exposure was broken in most (57.3%) of the homes using gas hobs and/or gas ovens that were tested under normal living conditions by leading scientific researchers.

NO₂ levels were found to be almost twice as high in kitchens, living rooms, and bedrooms in homes cooking on gas compared to those using electric appliances, on average. Breaches in 15.9% of homes using electric appliances were caused mainly by outside air pollution blowing in, the researchers say.

The research, commissioned by nonprofit energy efficiency group CLASP, was conducted by the Netherlands Organisation for Applied Scientific Research (TNO). Sensors were placed in 247 homes [1] in seven countries with large populations cooking on gas and childhood asthma cases linked to cooking on gas.

Breaching limit values increases health risks. NO₂ can cause inflammation of human airways, coughing and wheezing, reduced lung function, and increased asthma attacks, especially in children. Children in homes with a gas cooking appliance have a 20% increased risk of suffering a lower respiratory illness, the WHO estimates.

Pollution spikes in homes cooking on gas could last several hours and were more intense the longer the cooking time, the researchers found. Added together, the WHO daily limit was breached for 3.25 days over the 13-day testing period, on average. Where kitchens had fans to extract fumes outdoors, they did not clear much pollution. This is because of improper use, the researchers think.

Extrapolating to a year, the data shows that a quarter of homes (25%) cooking on gas breached EU and UK hourly NO₂ limits for outside air quality. Authorities across Europe have been forced to respond to breaches of these limits. Yet EU regulators have not set limits for indoor air pollution.

Little has been done to prevent NO₂ pollution from gas cooking appliances in Europe, CLASP wrote in its report summarizing the research. Various regulations could limit air pollution from appliances, but fail to, it said. The problem could be corrected at EU level next year when new design and labelling rules are expected to be adopted.

At a stakeholder meeting with EU officials, initially set for 30 November 2023 and postponed until March 2024, CLASP will call for a new EU energy label comparing gas and electric hob efficiency and highlighting pollution levels.

Nearly a third (32.5%) of homes in the EU cook on gas. But few are aware of the risks due to the invisible nature of the pollution, according to a recent opinion poll commissioned by CLASP and conducted by Opinium. If made aware, up to three quarters of respondents (74%) say they would consider getting rid of their gas appliances.

Nicole Kearney, CLASP Europe Director, said: “Our research reveals the severity of air pollution caused by gas cooking appliances in homes across Europe. Cooking up a change starts with awareness. Empowering people with knowledge on the health risks of these products is essential, and they need resources to upgrade to cleaner and healthier hobs and ovens. In turn, governments must protect public health, tackling air pollution at the source and supporting the transition to cleaner cooking.”

TNO senior scientist, Piet Jacobs, said: “Based on our field study data we estimate that in about 25% of the European kitchens cooking on gas the EU NO₂ limit value for 1-hour exposure is exceeded, where outside levels were below these values. Changing to electric cooking, preferably combined with use of well-designed ventilation hoods to reduce exposure to high levels of particulate matter from cooking, can bring these values down to below recommended levels.”

Professor Frank Kelly of Imperial College London said: “Gas hobs and ovens are a major source of indoor air pollution, including NO₂, which can both exacerbate existing health conditions and potentially lead to new respiratory illnesses. For children with asthma, the presence of gas cooking appliances can intensify their symptoms. Removing these appliances from our homes will improve indoor air quality and mitigate potential risks to public health.”

The scientists also measured for fine particulate matter. In kitchens, this is caused by outdoor pollution blowing in and food cooking, rather than the appliance fuel source. The scientists found no significant difference in emissions between homes cooking on gas and electric.

Notes

[1] Market research firm Opinium selected 40 homes each in France, Italy, the Netherlands, Romania, Slovakia, Spain, and the UK, where residents cook at least 3 days a week, are non-smokers, and are not near busy main roads or industrial plants. More than 40% of homes include children. One in 5 cook purely on electric, while 4 in 5 cook purely on gas, either ovens, hobs or both. In all homes, sensors were placed in the kitchen, living room and a bedroom to measure NO₂, fine particulate matter, and carbon monoxide. Outdoor sensors detected NO₂. Participants were told to cook and behave normally. Each was paid €100. Only data from 247 homes that successfully followed instructions over a 13-day period in 2023 were included. The previous largest EU study of exposure to NO₂ based on continuous sensor data took readings from 16 homes.

In collaboration with the Netherlands Organisation for Applied Scientific Research (TNO) and Opinium Research, CLASP conducted a study across seven European countries in 2023 to assess the impact of gas cooking on indoor air quality. The research involved monitoring in-home air quality in gas- and electric-cooking households, collecting household and cooking behaviour data, and analysing indoor pollutant concentration levels.

The report tackles several critical questions:

• What are the levels of indoor air pollution in households with gas cooking appliances and how do they compare to households that cook with electric appliances?
• How do these pollution levels compare to established mandatory outdoor air quality standards as well as pollution levels recommended by the WHO?
• Is ventilation enough to mitigate the health risks linked with gas cooking, or is a transition to cleaner cooking technologies necessary?

The report’s key findings provide a compelling call to action:

• Gas cooking often results in indoor air pollution that exceeds WHO air quality limits, putting citizens at risk of severe health issues.
• Many households with gas cooking appliances exceed WHO air quality guidelines for nitrogen dioxide (NO₂).
• Electric-cooking households, in contrast, enjoy significantly better indoor air quality, free from NO₂ pollution caused by kitchen appliances.
• Ventilation alone is insufficient to mitigate the pollution, necessitating a transition to cleaner electric cooking.

To safeguard public health, it’s essential to educate people about the health risks associated with gas appliances and provide them with resources to transition to cleaner and healthier cooking technologies. CLASP calls for collaborative efforts from governments, industry, civil society, healthcare providers, and individuals to improve indoor air quality across Europe.

GENEVA, SWITZERLAND – This week at the Minamata Convention on Mercury Fifth Conference of Parties (COP5), delegates from 147 countries agreed to phase out florescent lighting globally and completely by 2027.

Fluorescent lamps contain mercury, a potent neurotoxin.

The decision will accelerate global adoption of LEDs by effectively putting an end to the fluorescent lighting industry, with the limited exception of special uses like some transport applications. LEDs are on average 40% more energy efficient than fluorescents.

COP5 decisions primarily addressed linear fluorescent lamps (LFLs), the largest contributor to lighting-based mercury pollution in the world, ubiquitously found in offices, stores, and other commercial settings and institutions. LFLs are also a major source of energy-related CO2 emissions. The decisions close the loop on continued efforts to stop the manufacture, export and import of mercury in lighting worldwide.

Global markets are going all LED.

The benefits of a full transition to LEDs by 2027 are massive. The appliance efficiency expert group CLASP estimates the move will have the following benefits (cumulatively from the phase out dates to 2050):

• Avoid 2.7 gigatonnes of CO2 emissions
• Eliminate 158 tonnes of mercury pollution, both from the light bulbs themselves and from avoided mercury emissions from coal-fired power plants
• Save US$1.13 trillion on electricity bills

“The Africa region, in deep collaboration with colleagues around the world, are proud to have made momentous progress to Make Mercury History,” said David Kapindula, Minamata COP3 President and Africa Region expert. “The decision to phase out mercury-based fluorescent lighting will have unprecedented benefits in combatting the triple planetary crisis of climate change, air pollution, and biodiversity loss. Such actions would not have been possible without the spirit of cooperation demonstrated by Parties at this Minamata COP5.”

This week’s move complements decisions at Minamata COP4 in March 2022 to phase out compact fluorescent lamps (CFLs), lamps commonly found in homes, by 2025. Proposals to phase out fluorescents at COP4 and COP5 were introduced by delegates from Africa.

“I was pleased to see a high spirit of collaboration amongst the Parties as related to matters concerning mercury lighting,” said Itsuki Kuroda, co-chair for COP5 proceedings and the Delegate from Japan. “Parties were able to align on phase out dates for all fluorescent categories, representing a positive example of successful diplomacy on the world stage.”

Fluorescent lighting contains mercury, a toxic chemical that threatens the health of people and the planet. Most fluorescents are improperly disposed of into general waste streams; broken bulbs pollute land and water, and increase health risks in vulnerable populations like children, pregnant people, and waste workers.

“The mercury-free lighting community came together to achieve a significant feat in the fight against mercury added products. Putting a stop to all lighting-related mercury pollution will have wide reaching benefits for our communities, ecosystems, and for the generations to come. We congratulate the governments and are pleased to join them in saying ‘Farewell to Fluorescents,’” said Elena Lymberidi-Settimo, International Co-coordinator of the Zero Mercury Working Group.

LED lamps pay for themselves quickly in energy savings. Recent global analysis indicates that payback periods for LED alternatives to LFLs are improving, from an average of 6.3 months in 2022 to 2.4 months in 2023.

LED sales and manufacturing rates are increasing year on year while fluorescent manufacture and sales are plummeting. Apart from the specialized blue-chip components, LEDs can be manufactured and assembled anywhere, unlike fluorescents, which are only produced by a few companies in a handful of countries. Advocates claim that the transition to all LED will drive local economic growth, especially in low- and middle- income countries, due to the affordability and availability of the lamps and increased clean energy jobs.
