Happy Earth Day! I was only four years old when the first Earth Day took place. But as I began to work on climate change, I found it inspiring to look back at the photos from April 1970 and learn about what motivated 20 million people to action—and the impact of public mobilization on policy and practice in the years that followed.

Many of my friends in the climate movement are understandably cynical about what Earth Day has become today—in many ways, it has been reduced to calls for small individual acts (like picking up trash or composting coffee grounds) over the larger systemic changes and solutions that require much harder choices and trade-offs. Some companies have co-opted the day to sell more “environmentally friendly” products, or worse, to provide polluters with an opportunity to greenwash their miserable track records. But as a lifelong student of history and an unbridled optimist, I still find hope and inspiration in its radical roots.

Open Letter - various organizations, September 2021

We are a broad statewide coalition of 90 organizations, companies, and individuals, advocating for better and more equitable access to Electric Vehicle (EV) charging infrastructure in California. Recognizing that over half of California’s greenhouse gas emissions come from transportation, the state has set a clear path to electrify California’s light duty vehicle fleet. California’s built environment, however, fails to provide sufficient or equitable access to the EV charging infrastructure required to make this necessary transition. Since November of 2020, we have been involved in the CALGreen stakeholder engagement process, and from the beginning our mandate has been to ensure that every new multi-family housing unit with parking has access to some level of residential EV-ready charging.

Most Canadians experienced global heating directly this summer – and in British Columbia, the chief coroner attributed 570 of the 815 sudden deaths during the June extreme heat event to the record-breaking temperatures, as reported by the CBC. “July 2021 was Earth’s hottest month ever recorded, NOAA finds” (Washington Post, Aug. 13) states that the combined land and ocean-surface temperature in July was 1.67 degrees Fahrenheit above the 20th-century average, with North America 2.77 F above average. The IPCC Report released in August includes long-term temperature trends in its overview of the physical impacts of climate change, and makes dire forecasts for the future.

Health, earnings, and environmental justice

Two new medical articles on the theme of heat and health appeared in the prestigious journal The Lancet, and are summarized in “Extreme heat-caused deaths have jumped 74% in the last 30 years” in Axios in August.

Examining the economic impacts on workers, in mid-August the Union of Concerned Scientists (UCS) released Too hot to work: Assessing the Threats Climate Change Poses to Outdoor Workers. The UCS report is summarized in “If we ignore climate change, it will be hell on outdoor workers” in HuffPost, re-posted by the National Observer on August 24. One of its unique findings: a forecast that between now and 2065, (assuming no action to reduce global emissions), the exposure to hazardous levels of heat will quadruple, resulting in a potential loss of 10 percent or more of earnings annually for more than 7.1 million US workers. Economy-wide, this translates into up to $55.4 billion of earnings at risk annually. In Health Costs of Climate Change , published by the Canadian Institute for Climate Choices published in June 2021, the estimate for Canada was that the labour productivity impact of higher temperatures is projected as “a loss of 128 million work hours annually by the end of century—the equivalent of 62,000 full-time equivalent workers, at a cost of almost $15 billion.”

Too Hot to Work counts farm labourers and construction workers, but also truck drivers, delivery and postal workers, firefighters, police, and forestry workers as outdoor workers. Given that Black/African American and Hispanic/Latino workers disproportionately comprise many U.S. outdoor occupations, the report highlights the environmental justice aspects of extreme heat . This environmental justice aspect has been described anecdotally by many articles over the summer – notably, in the poignant text and photos of “Postcard From Thermal: Surviving the Climate Gap in Eastern Coachella Valley” (ProPublica, Aug. 17) , which contrasts the living conditions of the wealthy in California, living relatively unaffected, and the real suffering of the mainly immigrant workers who live close by and work on the farms and as service workers.

Coal miners like Dr. Jeremy Richardson’s family members helped power the country for generations—now he and Lee Anderson of the Utility Workers Union of America are working on how best to support them in a clean-energy economy.

By Elizabeth Perry - Work and Climate Change Report, May 12, 2021

Hard on the heels of the April statement by the United Mine Workers Union, Preserving Coal Country: Keeping America’s coal miners, families and communities whole in an era of global energy transition, the Utility Workers Union of America (UWUA) jointly released a report with the Union of Concerned Scientists on May 4: Supporting the Nation’s Coal Workers and Communities in a Changing Energy Landscape. This report is described as “a call to action for thoughtful and intentional planning and comprehensive support for coal-dependent workers and communities across the nation.” The report estimates that in 2019, there were 52,804 workers in coal mining and 37,071 people employed at coal-fired power plants – and that eventually all will lose their jobs as coal gives way to cleaner energy sources. Like the United Mine Workers, the report acknowledges that the energy shift is already underway, and “rather than offer false hope for reinvigorated coal markets, we must acknowledge that thoughtful and intentional planning and comprehensive support are critical to honoring the workers and communities that have sacrificed so much to build this country.”

Specifically, the report calls for a minimum level of support for workers of five years of wage replacement, health coverage, continued employer contributions to retirement funds or pension plans, and tuition and job placement assistance. The cost estimates of such supports are pegged at $33 billion over 25 years and $83 billion over 15 years —and do not factor in additional costs such as health benefits for workers suffering black lung disease, or mine clean-up costs. The report states: “we must ensure that coal companies and utilities are held liable for the costs to the greatest extent possible before saddling taxpayers with the bill.” Neither do the cost estimates include the recognized needs for community supports such as programs to diversify the economies, or support to ensure that essential services such as fire, police and education are supported, despite the diminished tax base. 

The report points to the precedents set by Canada’s Task Force on Just Transition for Canadian Coal Power Workers and Communities ( 2018), the German Commission on Growth, Structural Change and Employment (2019), as well as the New Mexico Energy Transition Act 2019 and the Colorado Just Transition Action Plan in 2020. The 12-page report, Supporting the Nation’s Coal Workers and Communities in a Changing Energy Landscape was accompanied by a Technical Report, and summarized in a UCS Blog which highlights the situation in Illinois, Michigan, and Minnesota. A 2018 report from UCS Soot to Solar also examined Illinois.

The shift to a low-carbon economy has proceeded largely without thoughtful plans or preparation for the workers and communities that have sustained the US economy for more than a century. The economic upheaval resulting from the dramatic job losses in the coal industry over the last decade has uprooted families, deepened economic anxiety, and left community leaders scrambling to keep schools open and social services in place. And the trend is set to continue: many more coal workers and communities are facing the same fate without intentional policies to address these changes.

As part of this shift, the nation must support coal workers in finding new career paths and help coal communities recover from the economic losses stemming from coal’s decline (see box). This will require long-term individual supports and benefits, long-term investments in community infrastructure, empowering local leadership to drive place-based solutions, and ensuring that the legacy of coal mines and coal-fired power plants is fully remediated. These elements are critical to a fair, just, and equitable move to low-carbon energy; are urgently needed; and must be sustained over time.

Ultimately, broader changes to our energy systems will impact a larger swath of fossil fuel–dependent workers and communities as we drive toward decarbonizing the economy by 2050. This policy brief focuses on coal-dependent workers because they have faced economic disruption over the past decade and are imminently threatened by the shift to lowcarbon energy in the near term.

But fortunately, there are solutions. New analysis by the Union of Concerned Scientists and the Utility Workers Union of America finds both that it is possible to support coal workers in the transition and that these comprehensive policies are affordable. Indeed, relative to the federal response to the Great Recession in 2008–2009 and the COVID-19 pandemic of 2020–2021, as well as the scale of investments needed to decarbonize our economy by 2050, investing in the nation’s coal workers comes with a relatively small price tag. Approximately 89,875 coal workers were employed in the United States in 2019. The cost of providing a comprehensive set of supports to the portion of these workers who will face job losses before reaching retirement age represents a tiny fraction of the estimated $2.5 trillion in additional capital investments in all energy sectors by 2030 that would be needed to reach net-zero emissions by 2050 (Larson et al. 2020). We estimate that the cost of these supports will range from $33 billion over 25 years to $83 billion over 15 years.

As the Biden administration considers federal resources for coal workers and their communities, the Utility Workers Union of America (UWUA) and the Union of Concerned Scientists (UCS) urge a set of comprehensive supports estimated to cost between $33 billion over 25 years to $83 billion over 15 years. The analysis, Supporting the Nation’s Coal Workers and Communities in a Changing Energy Landscape, underscores that a fair and equitable shift to a low-carbon economy requires intentional, robust, and sustained investments in coal workers, their families, and their communities.

Coal-fired electricity is down to 20 percent today from about half of the nation’s electricity generation a decade ago. With more closures on the horizon, a sustained and comprehensive set of supports is needed to ensure individuals who have powered America for generations can stay in their communities, prepare for new careers with family-sustaining wages, and can retire with dignity.

“For decades, the coal industry has simply locked its doors and forgotten the individuals and communities who rely on the coal industry and who exist in almost every state across the country,” said UWUA President James Slevin. “Approaching these closures with the right set of economic supports offers a better alternative to the chaos and devastation we’re seeing today.”

Recognizing coal and mining facilities often directly employ hundreds of individuals and many more indirectly across several counties, the economic and social infrastructure of a region undergoes lasting changes when facilities close.

“The economic upheaval resulting from the dramatic job losses in the coal industry over the last decade has uprooted families, deepened economic anxiety, and left community leaders scrambling to keep schools open and social services in place,” said report co-author Jeremy Richardson, a UCS senior energy analyst who comes from a family of coal miners. “But solutions are readily available with forward-looking and visionary action by policymakers.”

The approach of the 40th anniversary of Earth Day on April 22 provides us an opportunity to reflect on the “long, strange trip” shared by the environmental movement and the labor movement over four decades here on Spaceship Earth.

A billion people participate in Earth Day events, making it the largest secular civic event in the world. But when it was founded in 1970, according to Earth Day’s first national coordinator Denis Hayes, “Without the UAW, the first Earth Day would have likely flopped!”

Less than a week after he first announced the idea for Earth Day, Senator Gaylord Nelson presented his proposal to the Industrial Union Department of the AFL-CIO. Walter Ruther, President of the UAW, enthusiastically donated $2000 to help kick the effort off ““ to be followed by much more. Hayes recalls:

“The UAW was by far the largest contributor to the first Earth Day, and its support went beyond the merely financial. It printed and mailed all our materials at its expense — even those critical of pollution-belching cars. Its organizers turned out workers in every city where it has a presence. And, of course, Walter then endorsed the Clear Air Act that the Big Four were doing their damnedest to kill or gut.”

Some people may be surprised to learn that a labor union played such a significant role in the emergence of the modern environmental movement. When they think of organized labor, they think of things like support for coal and nuclear power plants and opposition to auto emissions standards.

When it comes to the environment, organized labor has two hearts beating within a single breast. On the one hand, the millions of union members are people and citizens like everybody else, threatened by air and water pollution, dependent of fossil fuels, and threatened by the devastating consequences of climate change. On the other hand, unions are responsible for protecting the jobs of their members, and efforts to protect the environment sometimes may threaten workers’ jobs. First as a working class kid and then as a labor official, I’ve been dealing with the two sides of this question my whole life.

Several articles and reports published recently have re-visited the question: how “clean” is “clean energy”? Here is a selection, beginning in October 2020 with a multi-part series titled Recycling Clean Energy Technologies , from the Union of Concerned Scientists. It includes: “Wind Turbine blades don’t have to end up in landfill”; “Cracking the code on recycling energy storage batteries“; and “Solar Panel Recycling: Let’s Make It Happen” .

“The glaring problem with Canada’s solar sector and how to fix it” (National Observer, Nov. 2020) states that “While solar is heralded as a clean, green source of renewable energy, this is only true if the panels are manufactured sustainably and can be recycled and kept out of landfills.” Yet right now, Canada has no capacity to recycle the 350 tonnes of solar pv waste produced in 2016 alone, let alone the 650,000 tonnes Canada is expected to produce by 2050. The author points the finger of responsibility at Canadian provinces and territories, which are responsible for waste management and extended producer responsibility (EPR) regulations. A description of solar recycling and waste management systems in Europe and the U.S. points to better practices.

“No ‘green halo’ for renewables: First Solar, Veolia, others tackle wind and solar environmental impacts” appeared in Utility Drive (Dec. 14) as a “long read” discussion of progress to uphold environmental and health and safety standards in both the production and disposal of solar panels and wind turbine blades. The article points to examples of industry standards and third-party certification of consumer goods, such as The Green Electronics Council (GEC) and NSF International. The article also quotes experts such as University of California professor Dustin Mulvaney, author of Solar Power: Innovation, Sustainability, and Environmental Justice (2019) and numerous other articles which have tracked the environmental impact, and labour standards, of the solar energy industry.

Regarding the recycling of wind turbine blades: A press release on December 8 2020 describes a new agreement between GE Renewable Energy and Veolia, whereby Veolia will recycle blades removed from its U.S.-based onshore wind turbines by shredding them at a processing facility in Missouri, so that they can be used as a replacement for coal, sand and clay in cement manufacturing. A broader article appeared in Grist, “Today’s wind turbine blades could become tomorrow’s bridges” (Jan. 8 2021) which notes the GE- Veoli initiative and describes other emerging and creative ways to deal with blade waste, such as the Re-Wind project. Re-Wind is a partnership involving universities in the U.S., Ireland, and Northern Ireland who are engineering ways to repurpose the blades for electrical transmission towers, bridges, and more. The article also quotes a senior wind technology engineer at the National Renewable Energy Laboratory in the U.S. who is experimenting with production materials to find more recyclable materials from which to build wind turbine blades in the first place. He states: “Today, recyclability is something that is near the top of the list of concerns” for wind energy companies and blade manufacturers alike …. All of these companies are saying, ‘We need to change what we’re doing, number one because it’s the right thing to do, number two because regulations might be coming down the road. Number three, because we’re a green industry and we want to remain a green industry.’”

These are concerns also top of mind regarding the electric vehicle industry, where both production and recycling of batteries can be detrimental to the planet. The Battery Paradox: How the electric vehicle boom is draining communities and the planet is a December 2020 report by the Dutch Centre for Research on Multinational Corporations (SOMO). It reviews the social and environmental impacts of the whole battery value chain, (mining, production, and recycling) and the mining of key minerals used in Lithium-ion batteries (lithium, cobalt, nickel, graphite and manganese). The report concludes that standardization of battery cells, modules and packs would increase recycling rates and efficiency, but ultimately, “To relieve the pressure on the planet, …. any energy transition strategy should prioritize reducing demand for batteries and cars… Strategies proposed include ride-sharing, car-sharing and smaller vehicles.”

Growth of solar panels and their lifespans

Solar energy is converted into electricity primarily with photovoltaic (PV) panels (there is another technology, called concentrating solar power, or CSP, but it is less commonly used and not addressed here). PV panels are comprised of individuals cells linked together, forming various shapes and sizes based on the needs of the system. The panels themselves are made with semiconductor materials—generally silicon, but sometimes various rare metals—and generally covered in glass.

The cost of PV panels has declined dramatically in recent years while their efficiency has gone up. These trends are continuing, leading to rapid growth of the solar industry globally. Solar panels on average last 25-30 years (and maybe even longer); thus, solar installations occurring today can be expected to remain productive until the middle of this century.

The reliability and longevity of new panels means that the volume requiring recycling or disposal is currently low, except for very early generations of PV panels and small numbers that may get broken during the installation process or damaged in storms.

However, options for recycling and disposal need to be addressed as PV production continues to ramp up. And while the larger recycling need may not come for another decade, infrastructure and policy should be put in place now to accommodate future needs.
