Global phase out of linear fluorescents delayed at Minamata Convention COP4

(eceee news, 29 Mar 2022) Bali, Indonesia – At the Minamata Convention on Mercury fourth Conference of Parties (COP4) , 137 governments adopted amendments to phase out a major category of fluorescent lighting. However, last-minute interventions delayed a decision on linear fluorescent lamps (LFLs), the long tubes commonly found in offices and stores, until Minamata COP5 in November 2023.

All fluorescent light bulbs contain mercury, a chemical of major public health concern according to the World Health Organization. In a major win for environmental and human health, the COP4 Parties agreed to phase-out compact fluorescent lamps (CFLs) by 2025. By accelerating the transition to LED lighting, which is more energy-efficient and non-toxic, the move will avoid 26.2 metric tonnes of mercury pollution and 261.5 million metric tons CO₂ emissions from 2025–2050, and save people $77.8 billion in lower energy bills.

“LEDs are a rare silver bullet technology – they’re ready now, they cost half as much to run as fluorescents, and they constitute a double win for climate change mitigation and reducing toxics pollution. We were amazed to see the international cooperation on lighting at COP4. We hope for continued global alignment and momentum at COP5,” said Corinne Schneider, Chief Communications Officer at CLASP, a global NGO focused on product efficiency.

Over days of intense negotiations, a group of countries came together to agree on phase-out dates for all lighting categories, including the EU, India, Indonesia, Japan, Norway, Pakistan, Switzerland, the US, and many Latin American governments, including Argentina, Bolivia, Brazil, Chile and Colombia. However, not all Parties were prepared to move forward, citing the need for more time and additional feasibility analysis.

A phase-out of LFLs by 2027 – the date that most countries rallied around by the end of the week – would increase the benefits by 90%, avoiding 71.7 million metric tons mercury pollution and 2.72 Gt of CO₂emissions and saving $1.06 trillion in cost savings, according to experts at CLASP.

Last year, 36 governments representing the Africa region submitted a proposal to the Minamata Convention to phase-out virtually all fluorescent lighting by the end of 2025. As many OECD countries will ban fluorescents in the coming years in favor of more efficient LEDs, less regulated markets risk becoming dumping grounds for toxic lighting.

“The Africa region recognizes that lighting is crucial in promoting livelihoods. Through our proposal, we took the first step towards a global phase-out of mercury-containing fluorescent lighting,” explained Oumar Cissé, Head of Delegation (Mali) in his opening statement at COP4. “The case to phasing out fluorescent lamps – both CFLs and LFLs – is already justified today from a public health, environmental, technical as well as economic perspective.” 

“The original proposal by the Africa region is consistent with our findings that a transition to clean and efficient lighting is feasible everywhere today. The move to phase out CFLs represents a major win, as it will remove toxic, inefficient bulbs from our homes. But keeping LFLs on the market continues to disadvantage our offices, hospitals, schools and childcare centers, needlessly increasing energy costs and risking mercury exposure,” said Ana Maria Carreño, Director of Climate at CLASP.  

Over the past year, NGO groups around the world advocated to address mercury in lighting at COP4. The Climate Action Network launched a petition that garnered over 200 signatures from climate and environmental groups, as well as the private sector, urging governments to take action to phase out fluorescents.  

“We are leaving this COP with mixed emotions. Un- and under-regulated markets are increasingly vulnerable to dumping of fluorescents that many countries have already banned due to their toxicity and inefficiency,” said Elena Lymberidi-Settimo, International Co-coordinator of the Zero Mercury Working Group. “The decision to phase out CFLs is one step in the right direction, and we congratulate governments for their efforts to progress the Convention’s promise to ‘Make Mercury History.’ We hope to see action on LFLs at COP5 in November 2023.”

“We are proud of the work the Africa region has done to protect people from toxic lighting products,” said Roger Baro, Vice President of COP4 (Burkina Faso). “We will continue working to phase-out all fluorescent lighting and stop it from causing further mercury pollution in our communities.”

Fluorescent lighting represents about 10% of mercury in all products globally. In the past, fluorescent lamps were promoted as an energy-efficient alternative to incandescent and halogen lamps, and the mercury risks were tolerated as a necessary tradeoff. Today, thanks to major advances in LED technology, mercury-free LED lamps can cost-effectively replace fluorescents in virtually all applications.
