How is it That Bitcoin is Becoming a Major Contributor to Carbon Emissions?
HUDSON VALLEY PRESS — t’s hard to believe that bitcoin could be the final nail in the coffin causing irreversible climate change

Dear EarthTalk: How is it that bitcoin, a virtual currency that few of us have heard of and no one I know uses, is becoming a major contributor to carbon emissions?
– Troy Sussman, Bowie, MD
It’s hard to believe that bitcoin, the best known of a group of new “cryptocurrencies” that many believe to be the future of money, could be the final nail in the coffin causing irreversible climate change. But a recent study from University of Hawai’i at Manoa researchers found that “projected bitcoin usage, if it follows the rate of adoption of other broadly adopted technologies, could alone produce enough carbon dioxide (CO2) emissions to push warming above 2°C within less than three decades.” According to the Intergovernmental Panel on Climate Change (IPCC), we can only hope to avoid the most cataclysmic effects of global warming if we can limit the rise in average global temperature to 2°C.
The reason bitcoin and other cryptocurrencies generate so much CO2 is that they require massive amounts of electricity, and our grid is still supplied primarily by fossil fuels. Bitcoin transactions are recorded and processed by dispersed individuals known as “miners” who group them together in blocks and add them to larger “chains” which serve as public ledgers of transactions.
“The verification process by miners, who compete to decipher a computationally demanding proof-of-work in exchange for bitcoins, requires large amounts of electricity,” reports study co-author Randi Rollins. Rollins estimates that bitcoin transactions accounted for some 69 million metric tons of CO2 emission in 2017 alone—and expects bitcoin-related emissions to rise sharply in the near future as the payment technology is adopted by millions around the world. If society adopts bitcoin as quickly as it adopted previous wildly popular “technologies” (e.g. credit cards, dishwashers), increased electricity demands could overwhelm efforts to curtail greenhouse gas emissions.
“We cannot predict the future of Bitcoin, but if implemented at a rate even close to the slowest pace at which other technologies have been incorporated, it will spell very bad news for climate change and the people and species impacted by it,” says the study’s lead author Camilo Mora.
“With the ever-growing devastation created by hazardous climate conditions, humanity is coming to terms with the fact that climate change is as real and personal as it can be,” she adds. “Clearly, any further development of cryptocurrencies should critically aim to reduce electricity demand, if the potentially devastating consequences of 2°C of global warming are to be avoided.”
Critics of the report counter that the global electric power sector—not to mention computers and cryptocurrency “rigs”—are getting significantly more energy efficient every year. Also, bitcoin and other cryptocurrencies might not be as widely adopted as researchers assume.
But isn’t it better we know now about the potential climate risks of bitcoin so we can work to direct the technology’s development in as environmentally friendly a way as possible? It certainly would be a shame to suffer the effects of runaway climate change after doing so much to lower our carbon footprints just because we neglected to hold cryptocurrencies to the same efficiency standards as the rest of the technologies we rely on.

OPINION: California’s Legislature Has the Wrong Prescription for the Affordability Crisis — Gov. Newsom’s Plan Hits the Mark
Last month, Gov. Newsom included measures in his budget that would encourage greater transparency, accountability, and affordability across the prescription drug supply chain. His plan would deliver real relief to struggling Californians. It would also help expose the hidden markups and practices by big drug companies that push the prices of prescription drugs higher and higher. The legislature should follow the Governor’s lead and embrace sensible, fair regulations that will not raise the cost of medications.

By Rev. Dr. Lawrence E. VanHook
As a pastor and East Bay resident, I see firsthand how my community struggles with the rising cost of everyday living. A fellow pastor in Oakland recently told me he cuts his pills in half to make them last longer because of the crushing costs of drugs.
Meanwhile, community members are contending with skyrocketing grocery prices and a lack of affordable healthcare options, while businesses are being forced to close their doors.
Our community is hurting. Things have to change.
The most pressing issue that demands our leaders’ attention is rising healthcare costs, and particularly the rising cost of medications. Annual prescription drug costs in California have spiked by nearly 50% since 2018, from $9.1 billion to $13.6 billion.
Last month, Gov. Newsom included measures in his budget that would encourage greater transparency, accountability, and affordability across the prescription drug supply chain. His plan would deliver real relief to struggling Californians. It would also help expose the hidden markups and practices by big drug companies that push the prices of prescription drugs higher and higher. The legislature should follow the Governor’s lead and embrace sensible, fair regulations that will not raise the cost of medications.
Some lawmakers, however, have advanced legislation that would drive up healthcare costs and set communities like mine back further.
I’m particularly concerned with Senate Bill (SB) 41, sponsored by Sen. Scott Wiener (D-San Francisco), a carbon copy of a 2024 bill that I strongly opposed and Gov. Newsom rightly vetoed. This bill would impose significant healthcare costs on patients, small businesses, and working families, while allowing big drug companies to increase their profits.
SB 41 would impose a new $10.05 pharmacy fee for every prescription filled in California. This new fee, which would apply to millions of Californians, is roughly five times higher than the current average of $2.
For example, a Bay Area family with five monthly prescriptions would be forced to shoulder about $500 more in annual health costs. If a small business covers 25 employees, each with four prescription fills per month (the national average), that would add nearly $10,000 per year in health care costs.
This bill would also restrict how health plan sponsors — like employers, unions, state plans, Medicare, and Medicaid — partner with pharmacy benefit managers (PBMs) to negotiate against big drug companies and deliver the lowest possible costs for employees and members. By mandating a flat fee for pharmacy benefit services, this misguided legislation would undercut your health plan’s ability to drive down costs while handing more profits to pharmaceutical manufacturers.
This bill would also endanger patients by eliminating safety requirements for pharmacies that dispense complex and costly specialty medications. Additionally, it would restrict home delivery for prescriptions, a convenient and affordable service that many families rely on.
Instead of repeating the same tired plan laid out in the big pharma-backed playbook, lawmakers should embrace Newsom’s transparency-first approach and prioritize our communities.
Let’s urge our state legislators to reject policies like SB 41 that would make a difficult situation even worse for communities like ours.

Congress Says Yes to Rep. Simon’s Disability Hiring and Small Biz Support Bill
“As the first congenitally blind person to serve in Congress, I am incredibly honored to lead and excited to celebrate the House passage of the ‘ThinkDIFFERENTLY About Disability Employment Act,’” said Simon.

By Bo Tefu, California Black Media
The House of Representatives unanimously passed the “ThinkDIFFERENTLY About Disability Employment Act” on June 3, marking a major win for U.S. Rep. Lateefah Simon (D-CA-12) and co-sponsor Rep. Pete Stauber (R-MN-08) in their bipartisan effort to promote inclusive hiring and boost small business accessibility.
The legislation establishes a federal partnership between the Small Business Administration (SBA) and the National Council on Disability to help small businesses across the U.S. hire more individuals with disabilities and provide resources for disabled entrepreneurs.
“As the first congenitally blind person to serve in Congress, I am incredibly honored to lead and excited to celebrate the House passage of the ‘ThinkDIFFERENTLY About Disability Employment Act,’” said Simon.
“Small businesses are the lifeblood of cities, making them accessible for all will maximize local economic activity and broaden the job market to everyone who is seeking to contribute to their communities,” she continued. “Investments in business and talent in our communities shouldn’t be limited to just those who are not disabled. Full stop, period.”
Since taking office in January 2025, Simon has introduced six bills. The House has approved two of them: this measure and the “Assisting Small Businesses, Not Fraudsters Act.”
Simon, a lifelong disability rights advocate and former BART board member, has focused her career on improving access, from public transit to the job market.

Over 500 Join Interfaith Rally in Solidarity with Los Angeles Resistance to Trump Invasion
Over 500 people attended the Tuesday evening rally in Oakland, which was held simultaneously with a prayer vigil in Los Angeles, where rabbis, pastors, Muslim faith leaders, and indigenous spiritual leaders gathered to pray and speak out about the federal government’s abuses of power.

By Post Staff
n response to last week’s “invasion” of Los Angeles by armed and masked federal agents, East Bay faith leaders and community members, joined by Oakland Mayor Barbara Lee and Alameda County Supervisor Nikki Fortunato Bas, held an Interfaith vigil Tuesday evening at Oakland’s Fruitvale Plaza in support of Los Angeles residents and immigrant communities across the country.
Over 500 people attended the Tuesday evening rally in Oakland, which was held simultaneously with a prayer vigil in Los Angeles, where rabbis, pastors, Muslim faith leaders, and indigenous spiritual leaders gathered to pray and speak out about the federal government’s abuses of power.
Earlier on the same day, hundreds of protesters at San Francisco and Concord immigration courts shut down the courts after masked, plainclothes federal ICE agents detained people seeking asylum attending their court hearings.
“Too many families in Los Angeles torn apart by this invasion still do not have access to a lawyer — and that’s not an accident. We, the people, the community, are here to say, ‘Enough!’ We must keep organizing and demand that ICE and our government respect the rights of all people and uphold the principle of due process,” said Andrés Pomart with Trabajadores Unidos Workers United.
“We know that when we organize, we win. That’s why our communities – Black, Brown, and working-class – are coming together to support each other in solidarity. Together, as immigrant communities and as a united working class, we will not be divided nor intimidated nor live in fear,” Pomart said.
“Immigrant communities — yes, our immigrant communities — are the heartbeat of Oakland, enriching our neighborhoods with diverse cultures, languages and experience, and deserve the quality of life that every human being deserves. An attack on one of us is an attack on all of us. “Your city remains committed to protecting our immigrant neighbors,” said Mayor Lee.
“When Trump’s armed goons come for our families and communities, when they trample on our shared values of freedom and opportunity, when they make a mockery of our rights to due process, we are called to step up for our neighbors,” said Supervisor Bas. “This is not just an immigration story. It’s a story about who we are — and how we respond when our neighbors are under attack and when the president of the United States abuses his powers. When they come for one of us, they come for all of us.”
Said Kampala Taiz-Rancifer, the Oakland teachers’ union president, “It is time for us to say, ‘Not in our city.’ We will stop, we will block, we will drive out ICE. We will protect our classrooms. We will protect our streets. We will protect our homes. Together, we rise for the dignity of our families and our right to live without fear.”
“I feel that the president and the current administration is grossly overstepping and abusing their power,” Rabbi Chai Levy, speaking to KQED. “I feel that, as a religious person, communities of faith need to show up and stand in solidarity with immigrants who are threatened and afraid. “It’s important to show up as people of conscience and morality and say that we’re against what our government is doing.”
The vigil was hosted by Bay Resistance, and co-sponsoring organizations included the Alameda Labor Council, Alliance of Californians for Community Empowerment (ACCE), Faith in Action East Bay, Restore Oakland, East Bay Alliance for a Sustainable Economy (EBASE), Ella Baker Center for Human Rights, Oakland Rising, Faith Alliance for a Moral Economy, SEIU Local 1021, Communities United for Restorative Youth Justice (CURYJ), SEIU United Service Workers West, Jewish Voice for Peace Bay Area, Jobs with Justice San Francisco, Interfaith Movement for Human Integrity, Urban Peace Movement, and Trabajadores Unidos Workers United.
