The 26th United Nations Climate Change Conference (COP26), held in Glasgow, Scotland, served as a global platform for discussing urgent environmental challenges—and surprisingly, one of the emerging topics was the role of cryptocurrency in sustainable development. Cointelegraph Editor-in-Chief Kristina Cornèr took the stage to offer expert insights into how the crypto ecosystem can contribute positively to climate action, challenging widespread misconceptions about blockchain technology’s environmental impact.
With a strong background in energy efficiency and green innovation—having previously worked as Communications Manager at France’s Alliance for Energy Efficiency and Ecological Enterprises, and later as a researcher at the ENERPO Centre of the College of Europe—Cornèr brought both credibility and depth to her discussion on digital assets and ecological responsibility.
Bridging Technology and Environmental Stewardship
Cornèr emphasized that the decentralized nature of blockchain offers a unique alternative to traditional, centralized systems often associated with inefficiency and narrow-mindedness. She described decentralization not just as a technological shift, but as a philosophical one:
“Decentralization is the antidote to siloism—or, in English, parochialism. It’s a shift from local, fragmented thinking to a global, interconnected vision.”
This mindset, she argued, is essential for tackling climate change—a challenge that transcends borders and demands collaborative innovation across sectors.
At COP26, Cornèr highlighted how the rapid evolution of blockchain technology mirrors broader transitions in the energy sector. While early iterations of any new industry come with inefficiencies, she stressed that dismissing entire fields based on initial shortcomings limits progress. Bitcoin mining, often criticized for high energy consumption, was a focal point of her address.
“Of course, every new industry has its pitfalls. But we’re actively working toward greener solutions. What matters most in the blockchain space is that people are ready to think differently and solve problems creatively.”
She pointed out that many miners are now transitioning to renewable energy sources such as hydro, solar, and wind power. In fact, recent data suggests that over 50% of Bitcoin’s network is powered by clean energy—a figure that continues to grow as regulatory pressures and market incentives align with sustainability goals.

The Crypto Climate Accord: A Unified Push for Net-Zero
One of the most promising developments Cornèr discussed was the Crypto Climate Accord, a voluntary initiative modeled after the Paris Agreement. This coalition unites more than 150 companies from the cryptocurrency, blockchain, tech, and energy sectors—including Consensys, the Web3 Foundation, Ripple, Near Protocol, and Pixl8—with a shared mission: achieving net-zero carbon emissions by 2030.
The accord focuses on three key pillars:
- Accelerating the adoption of renewable energy in blockchain operations
- Developing transparent carbon accounting standards
- Promoting interoperability between green technologies and decentralized networks
Cornèr praised the initiative as a prime example of cross-industry collaboration. Unlike traditional energy lobbies, which often resist change due to entrenched interests, the crypto community has shown agility and openness to reform.
“Innovation isn’t just about code or hardware. It’s about synergy. It goes beyond technology and people—it’s about us, collectively shaping the future.”
This human-centric perspective resonated throughout her talk, reinforcing the idea that technological advancement must serve planetary well-being.
Addressing Misconceptions About Bitcoin Mining
Despite growing awareness, public perception still lags behind reality when it comes to Bitcoin’s environmental footprint. Critics often cite outdated statistics from 2018–2019, when coal-heavy grids powered much of China’s mining activity—before Beijing’s 2021 crackdown forced miners to relocate to regions with abundant hydroelectric or geothermal power.
Today, major mining hubs in countries like Iceland, Canada, Norway, and Kazakhstan leverage low-cost renewables. Some operators even use flared natural gas—otherwise wasted in oil fields—to generate electricity for mining rigs, effectively turning pollution into productive energy use.
Cornèr reminded the audience that context matters: while Bitcoin does consume energy, so do legacy systems like banking infrastructure and gold mining—both of which rarely face comparable scrutiny.
“We measure Bitcoin’s impact meticulously, yet we overlook the hidden costs of traditional finance. Let’s apply the same standards across all systems.”
She urged policymakers and environmental advocates to engage with the crypto community rather than dismiss it outright. Constructive dialogue, she argued, could unlock innovative financing models for climate projects—such as tokenized carbon credits or decentralized green bonds.

Synergy Between People, Technology, and Education
A recurring theme in Cornèr’s speech was the importance of education in driving meaningful change. She observed that many summit attendees pay lip service to sustainability while continuing business-as-usual practices—a hypocrisy she believes stems from a lack of systemic understanding.
“The key to historic transformation isn’t radical overhaul—it’s new synergies between people, technology, and education.”
By integrating blockchain into climate monitoring systems—such as tracking reforestation efforts or verifying supply chain sustainability—the technology can enhance transparency and accountability. Projects like verifiable credentials for carbon offsets or decentralized identity for green certifications are already gaining traction.
Moreover, decentralized autonomous organizations (DAOs) are emerging as novel vehicles for funding environmental startups and grassroots movements—offering faster, more democratic alternatives to traditional grant-based models.
Frequently Asked Questions (FAQ)
Q: Is cryptocurrency really becoming more sustainable?
A: Yes. The industry is rapidly shifting toward renewable energy sources. Over half of Bitcoin mining now relies on clean energy, and initiatives like the Crypto Climate Accord are pushing for full decarbonization by 2030.
Q: How does blockchain help fight climate change beyond reducing energy use?
A: Blockchain enables transparent tracking of carbon credits, supply chains, and environmental data. It also supports new funding models through DAOs and tokenized green assets.
Q: Wasn’t Bitcoin banned in some countries due to environmental concerns?
A: Some nations have restricted or banned crypto activities citing environmental reasons, but these decisions often reflect broader regulatory concerns. Many others are embracing sustainable mining practices instead.
Q: Can individuals contribute to greener crypto adoption?
A: Absolutely. Users can support eco-conscious blockchains (like those using proof-of-stake), choose wallets and exchanges powered by renewables, and advocate for transparency in energy reporting.
Q: Are there measurable results from green crypto initiatives?
A: Yes. For example, several mining firms now publish annual sustainability reports, and platforms like Energy Web are deploying blockchain-based renewable energy certificate systems across Europe.
A Call for Collective Responsibility
Cornèr concluded her address with a powerful message about unity and shared purpose:
“The crypto community is ambitious, bold, and full of potential. Innovation is about synergy—it transcends technology and people. It’s about our collective future.”
As global leaders continue debating climate policy, the inclusion of digital asset innovators in forums like COP26 marks a turning point. Rather than being seen as part of the problem, cryptocurrencies are increasingly recognized as potential catalysts for environmental solutions—provided they’re guided by responsibility, transparency, and collaboration.
