UN Report: AI Boom Drives 150% Surge in Tech Giants’ Indirect Emissions

/in /tarafından

A new United Nations report revealed on Thursday that indirect carbon emissions from the operations of four major AI-driven tech giants—Amazon, Microsoft, Alphabet, and Meta—rose by an average of 150% between 2020 and 2023. The sharp increase is largely driven by the vast energy demands of data centers powering artificial intelligence systems.

The report, published by the International Telecommunication Union (ITU), the U.N.’s digital technologies agency, analyzed the greenhouse gas emissions of 200 leading digital companies over the three-year period. Indirect emissions include those generated from purchased electricity, heating, cooling, and steam consumed by a company’s operations.

Among the companies surveyed, Amazon posted the largest rise, with operational carbon emissions soaring 182% over the period. Microsoft followed with a 155% increase, while Meta and Alphabet saw rises of 145% and 138%, respectively.

The growing reliance on AI has led to surging energy demands, with electricity consumption from data centers growing four times faster than overall global electricity usage, according to the ITU. The report projects that carbon emissions from top-emitting AI systems could eventually reach 102.6 million tons of carbon dioxide equivalent annually, further straining existing energy infrastructures.

In response, several companies highlighted their ongoing sustainability efforts. Meta referred Reuters to its sustainability report, stating that it is taking steps to reduce emissions, energy use, and water consumption in its data centers. Amazon emphasized its investments in carbon-free energy projects, including both nuclear and renewable sources. Microsoft pointed to its recent progress in improving energy efficiency, including transitioning to chip-level liquid cooling technologies that consume less energy than traditional cooling systems.

However, the ITU noted that while more digital companies are setting ambitious emissions targets, many of these commitments have yet to translate into meaningful reductions in actual emissions. The report underscores the growing challenge of balancing AI’s rapid expansion with environmental sustainability.

Broadcom Raises Revenue Forecast on AI Chip Demand but Shares Dip

/in /tarafından

Broadcom delivered a stronger-than-expected revenue forecast for its third quarter, supported by robust demand for its networking and custom AI computing chips. The company projected Q3 revenue of approximately $15.80 billion, exceeding analysts’ average estimate of $15.71 billion according to LSEG data.

Despite the upbeat forecast, Broadcom’s shares fell 4% in after-hours trading. The stock had already climbed nearly 30% over the past month and around 12% for the year, leading some investors to view the forecast as insufficiently exceeding high market expectations. “Clearly, expectations were high coming into the print,” said Kinngai Chan, senior research analyst at Summit Insights Group.

The Palo Alto-based company plays a crucial role in the AI hardware ecosystem, designing custom processors and networking chips for major AI and cloud computing clients such as OpenAI and Google. Broadcom has begun shipping its newest networking chip, the Tomahawk 6, which doubles the performance of its predecessor and enhances data center efficiency for AI workloads.

Broadcom CEO Hock Tan highlighted the ongoing growth, noting that AI semiconductor revenue is expected to accelerate to $5.1 billion in the third quarter, marking ten consecutive quarters of growth. “Our hyperscale partners continue to invest,” Tan stated. In contrast, non-AI semiconductor revenue remains sluggish and near the bottom of its cycle.

For the second quarter, Broadcom reported total revenue of $15 billion, narrowly surpassing analysts’ estimates of $14.99 billion. Revenue from its semiconductor segment, which includes products for data centers and networking, grew 16.7% year-over-year to $8.41 billion.

Google Cuts 200 Jobs in Global Business Unit Amid AI-Focused Shift

Google has laid off approximately 200 employees from its global business organization, which oversees sales and partnerships, as the tech giant continues to reallocate resources toward artificial intelligence and data centers, The Information reported Wednesday.

Key Highlights:

  • The cuts were confirmed by Google, which said the changes aim to boost collaboration and enhance customer service effectiveness.

  • This follows earlier layoffs in Google’s platforms and devices division, impacting teams responsible for Android, Pixel, and Chrome.

  • Google-parent Alphabet previously cut 12,000 jobs in January 2023, about 6% of its global workforce.

Broader Tech Industry Context:

Major tech companies are trimming headcount in legacy areas while aggressively investing in AI capabilities:

  • Meta laid off 5% of its “lowest performers” while accelerating AI hiring.

  • Microsoft let go of 650 staff from its Xbox division last September.

  • Amazon and Apple have also enacted selective layoffs across various departments.

These actions signal a strategic pivot across the tech industry to optimize cost structures and prioritize innovation in AI, cloud infrastructure, and machine learning tools.
