Executive Overview
In the public relations machinery of Silicon Valley, few narratives are pushed with as much fervor as the marriage of artificial intelligence and environmental salvation. Tech titans routinely frame generative AI, machine learning, and massive data center expansions as the ultimate tools for solving the climate crisis—optimizing smart grids, accelerating material science, and predicting weather patterns with unprecedented precision. At the epicenter of this narrative sits NVIDIA, the world’s most dominant chipmaker, whose graphics processing units (GPUs) power the vast majority of the global artificial intelligence revolution.
Yet, a bombshell investigative report titled NVIDIA’s AI Climate Hoax, authored by clean energy analyst Ketan Joshi for Greenpeace International and a coalition of civil society partners, shatters this meticulously constructed corporate illusion. Behind NVIDIA’s glossy sustainability messaging and triumphant proclamations of technological progress lies a staggering, rapidly accelerating carbon footprint.
According to the new research, NVIDIA’s indirect Scope 3 emissions—those generated across its vast, complex supply chain and through the downstream use of its products—have skyrocketed by an astonishing 725% since 2020. Furthermore, the report reveals a ticking carbon time bomb: undisclosed emissions stemming directly from the operation of NVIDIA chips already sold into the market could add up to an alarming 21 million tonnes of carbon dioxide equivalent ($textCO_2texte$) by the year 2025 alone.
The briefing systematically dismantles the core greenwashing tactics employed by the tech giant. It exposes how NVIDIA masks its soaring energy consumption behind marginal hardware efficiency gains, promotes data center "demand response" programs as renewable drivers when they often perpetuate fossil fuel reliance, and claims a net climate benefit while supplying the silicon backbone for hyper-scale data centers powered by fossil gas.
Beyond its direct carbon accounting, the report implicates NVIDIA in a modern incarnation of "tech colonialism." By anchoring its manufacturing supply chains in East Asian industrial hubs heavily dependent on coal and natural gas, NVIDIA effectively offloads its heavy ecological burdens onto lower-income nations, concentrating astronomical wealth in the Global North while inflicting localized environmental injustice—characterized by extreme energy strain, severe water depletion, and rapid land degradation—on communities hosting its infrastructure.
As civil society groups demand immediate, radical accountability, the findings serve as a sobering wake-up call for regulators, investors, and consumers alike: the artificial intelligence gold rush is accelerating the climate crisis, and its most profitable architect is attempting to code away its culpability with clever marketing.
Detailed Chronology: The Escalation of NVIDIA’s Emissions Crisis
To understand how NVIDIA arrived at its current environmental crossroads, it is necessary to trace the convergence of the generative AI explosion and the company’s manufacturing strategy over the past half-decade.
2020–2021: The Pandemic Pivot and the Foundations of Scale
Long before OpenAI’s ChatGPT captured the global imagination in late 2022, NVIDIA was quietly cementing its monopoly over high-performance computing. During the COVID-19 pandemic, demand for cloud infrastructure surged, prompting a massive scaling of data center builds.
In this period, NVIDIA’s Scope 3 emissions—which encompass the lifecycle of its products, from the extraction of raw minerals to the electricity consumed by servers housing its GPUs—began a steep upward trajectory. However, because the tech industry historically underreported downstream energy use, these early increases were largely obscured by corporate sustainability reports that emphasized operational (Scope 1 and 2) efficiency, such as LED lighting in corporate offices and minor tweaks to office building energy use.
2022–2023: The Generative AI Gold Rush
The launch of generative AI tools in late 2022 triggered an unprecedented industrial land grab. Technology conglomerates—including Microsoft, Alphabet, Amazon, and Meta—began stockpiling NVIDIA H100 GPUs by the tens of thousands to train massive foundational models.
NVIDIA’s financial fortunes soared, turning the chipmaker into a trillion-dollar corporate titan. Yet, this commercial triumph came with an invisible environmental toll. The manufacturing of advanced semiconductors is one of the most resource-intensive industrial processes on Earth, requiring hyper-pure silicon, toxic chemicals, vast amounts of ultra-clean water, and uninterrupted, high-capacity electricity. As NVIDIA outsourced its physical production to foundries primarily located in East Asia—such as Taiwan Semiconductor Manufacturing Company (TSMC)—its indirect supply chain emissions began to multiply exponentially.
2024–2025: The Transparency Gap and the 725% Surge
By 2024, independent researchers and climate watchdogs began scrutinizing the vast discrepancy between NVIDIA’s green rhetoric and the physical reality of grid expansion. Data centers required to train and run modern AI models were no longer drawing mere megawatts; they were demanding gigawatts of power, rivaling the energy consumption of entire small nations.
The new Greenpeace International analysis reveals that by 2025, NVIDIA’s indirect Scope 3 emissions have surged by 725% compared to baseline figures from 2020. Crucially, the report highlights a massive transparency loophole: the emissions generated by the millions of chips operating in the wild—consuming continuous, heavy streams of electricity over their operational lifespans—remain largely undisclosed or drastically underestimated in standard corporate disclosures. The report estimates that these hidden operational emissions alone will account for a staggering 21 million tonnes of $textCO_2texte$ in 2025.
2026: The Public Confrontation and the Release of The AI Climate Hoax
Published in September 2026, The AI Climate Hoax marks a turning point in corporate accountability. Authored by Ketan Joshi in collaboration with a coalition of international civil society organizations, the report strips away the veneer of NVIDIA’s marketing campaigns, laying bare the mechanics of its environmental footprint and initiating a global debate over the true cost of artificial intelligence.
Supporting Context & Metrics: Deconstructing the Greenwashing Tactics
The investigation does not merely point to rising emissions numbers; it meticulously details the three core psychological and corporate greenwashing tactics NVIDIA utilizes to deflect criticism and delay meaningful climate action.
1. The "Net Climate Benefit" Fallacy
NVIDIA frequently asserts that the computational power of its hardware enables scientific breakthroughs that will ultimately save the planet—such as modeling climate change, optimizing smart grids, or discovering carbon-capture materials.
- The Reality: As the briefing notes, this is a speculative accounting trick. Trading theoretical, future climate savings against guaranteed, immediate, and massive carbon emissions today is a dangerous logical fallacy. While AI can assist in efficiency modeling, the net effect of deploying millions of high-wattage GPUs is an immediate and catastrophic acceleration of energy demand, which grids are currently meeting by keeping coal and gas plants online longer than planned.
2. Masking Energy Consumption Behind Efficiency Gains
A cornerstone of NVIDIA’s defense is that each new generation of chips (such as the transition from Ampere to Hopper and Blackwell architectures) offers greater "energy efficiency" per floating-point operation (FLOP).
- The Reality: This phenomenon is a classic manifestation of Jevons Paradox, where increased efficiency drives down the effective cost of use, leading to a massive increase in total consumption. Even if an individual H100 or Blackwell GPU uses less energy per calculation than its predecessor, the absolute number of chips deployed globally has exploded by orders of magnitude. The total volume of computation has outstripped efficiency gains many times over, resulting in skyrocketing absolute energy consumption.
3. Misrepresenting Data Center Demand Response as Renewable Drivers
Tech companies often sign power purchase agreements (PPAs) with wind and solar developers or point to "demand response" capabilities—where data centers temporarily curtail their power use during grid emergencies—as proof that they are driving the clean energy transition.
- The Reality: The report exposes how these mechanisms are frequently used as a smoke screen. For instance, NVIDIA hardware is slated to power monstrous new data center hubs, such as a proposed mega-facility in Ohio that relies directly on energy backed by one of the world’s largest fossil gas plants. Rather than driving new renewable capacity onto the grid, AI data centers are often keeping aging fossil-fuel infrastructure alive or forcing utilities to delay coal plant retirements to satisfy round-the-clock baseload demands.

+--------------------------------------------------------------------------+The Geopolitical Dimension: Tech Colonialism and Environmental Injustice
A particularly vital contribution of the 2026 report is its framing of NVIDIA’s supply chain dynamics through the lens of environmental justice.
NVIDIA’s chip design and intellectual property ownership remain firmly rooted in the affluent tech hubs of the Global North, capturing immense financial wealth. However, the physical manufacturing of its silicon relies heavily on intricate supply chains embedded in East Asia, where regional electricity grids still lean heavily on fossil fuels.
By outsourcing manufacturing, NVIDIA effectively offloads the severe ecological burdens—toxic waste streams, massive water consumption in drought-prone regions, and carbon-heavy industrial processes—onto lower-income nations and vulnerable communities. This dynamic creates a system of "tech colonialism," where the Global South absorbs the environmental degradation while the Global North reaps the financial dividends of the artificial intelligence boom.
Official Statements and Author Insights
The release of The AI Climate Hoax has reverberated through corporate boardrooms, environmental policy circles, and international media outlets.
Ketan Joshi on Corporate Accountability
Ketan Joshi, the lead author of the report and an internationally recognized analyst in clean energy and corporate accountability, did not mince words regarding the tech sector’s evasiveness. In accompanying statements, Joshi emphasized that the tech industry has successfully co-opted the language of environmentalism while scaling up fossil-fuel dependency at an unprecedented rate.
"NVIDIA has positioned itself as the benevolent architect of a high-tech green future, but our research proves that the emperor has no clothes," Joshi stated. "When you look past the corporate PR and examine the supply chain math, you see an unprecedented surge in carbon pollution. You cannot claim to be a climate savior while powering the fossil-fueled expansion of hyper-scale data centers."
Joshi, whose previous works include Windfall: unlocking a fossil free future and the Greenpeace Australia Pacific report Energy Vampires (2026), has consistently warned that corporate commitments to sustainability are failing to keep pace with the hyper-exponential growth of computational infrastructure.
The Civil Society Coalition
The report’s credibility is amplified by the broad coalition of international organizations that collaborated on its research. Participating groups issued a joint statement demanding immediate transparency and structural reform across the technology sector:
- Stand.earth: Emphasized that tech companies must be held to the same stringent climate disclosure standards as heavy industry and fossil fuel corporations.
- Climate Action Against Disinformation (CAAD): Highlighted how greenwashing narratives surrounding AI distort public policy debates and undermine genuine climate action.
- The Green Web Foundation & Green Screen Coalition: Pointed out the urgent need to address the digital infrastructure footprint, noting that software efficiency must be matched by radical improvements in hardware energy sourcing.
- Kairos Fellowship, Beyond Fossil Fuels, and Friends of the Earth: Stressed that frontline communities bearing the brunt of data center water and energy strains are being ignored in the rush for AI supremacy.
Future Outlook: Demands for Reform and the Road Ahead
As the artificial intelligence industry enters the latter half of the 2020s, the confrontation between digital expansion and planetary boundaries is reaching a critical tipping point. The findings in NVIDIA’s AI Climate Hoax provide a clear roadmap for what must happen next if the tech sector is to avoid catastrophic climate failure.
Greenpeace’s Core Demands for NVIDIA
Greenpeace International and its partner organizations have laid out non-negotiable demands for NVIDIA and the broader semiconductor industry:
- Abandon Greenwashing Illusions: NVIDIA must immediately cease misleading public relations campaigns that frame AI hardware as a net climate benefit without rigorous, transparent, and independently verified lifecycle carbon accounting.
- Direct Financial Responsibility: The company must invest deeply and directly in new, additional global renewable energy capacity, moving beyond creative carbon offsets and standard corporate power purchase agreements that fail to green the grid.
- Supply Chain Decarbonization by 2030: NVIDIA must expand its 100% renewable energy procurement targets across its entire manufacturing supply chain—including its foundry partners in East Asia—with a strict deadline of 2030.
- Complete Emissions Transparency: Full disclosure of all Scope 3 downstream emissions, specifically accounting for the continuous electricity consumption of every chip sold over its operational lifecycle, must become standard practice in corporate reporting.
The Broader Implications for the Tech Sector
NVIDIA is not operating in a vacuum. Every major technology conglomerate investing in generative AI faces a similar reckoning. As grid operators in the United States, Europe, and Asia warn of rolling blackouts and delayed coal plant retirements driven by data center loads, regulators are beginning to cast a skeptical eye on tech sector sustainability pledges.
The era of unchecked, self-regulated digital expansion is drawing to a close. If companies like NVIDIA wish to retain their social license to operate in a warming world, they must transition from hiding behind sophisticated marketing to enacting radical, verifiable decarbonization across every link of their silicon supply chain. The alternative is a future where the computational power used to simulate climate solutions ends up accelerating the very crisis it seeks to solve.
