Amazon’s AI push is undermining its sustainability goals

engadget.com Unknown 2025-07-22 06:01:59

Amazon’s decarbonization goals are being undermined by its push to be a leader in generative AI. Its most recent sustainability report concedes its overall carbon emissions grew for the first time since 2022. It reported a six percent increase in its carbon footprint across 2024, laying much of the blame at the feet of its data center rollout. The reported increase is significant given Amazon’s method of reporting its own environmental impact. Critics have suggested the mega-retailer “ dramatic

Meet the cement transport ship that makes cement ingredients while sailing

techcrunch.com Tim De Chant 2025-07-24 22:11:50

Shipping has a pollution problem, but one company has a solution that does more than just eliminate a boat’s carbon dioxide. London-based Seabound has developed a carbon capture system that transforms CO 2 from the engine into limestone, a key ingredient in cement. Fittingly, the company has installed it aboard the UBC Cork, a cement carrier currently sailing through the Mediterranean Sea. When the ship docks in Norway, the limestone created from the voyage will be offloaded and used to make m

East Asian aerosol cleanup has likely contributed to global warming

RAMIP simulations and recent emissions changes in East Asia We first document the emissions perturbation applied in the RAMIP baseline and East Asia simulations21 (see “Methods”), and compare them to the actual emissions reductions from the same region since around 2010. Briefly, RAMIP isolates the climate effects of aerosol emissions in one region by comparing two sets of transient emission simulations; one following a global, high emissions pathway (SSP3-7.0, which assumes weak air quality po

5th Avenue Apple Store spray-painted by climate protesters calling for boycott

New York’s flagship Fifth Avenue Apple Store was spray-painted by climate change protesters, calling for a boycott of the company. Three slogans were sprayed onto the glass frontage of the store, with Extinction Rebellion accusing Apple of hypocrisy on environmental issues … Three messages were sprayed onto the glass panes of the iconic storefront: (Apple logo) Boycott Dump Trump, Apple!

Lost in Space: A ‘Game-Changing’ Emissions Satellite Just Went Dark

gizmodo.com Ellyn Lapointe 2025-08-13 06:30:03

An $88 million satellite backed by billionaire Jeff Bezos is lost in space. MethaneSAT, designed to sniff out sources of methane emissions across the globe, only survived about 15 months in Earth’s orbit before meeting its untimely end. The Environmental Defense Fund (EDF), which launched the satellite in March 2024, announced its demise on July 1. The organization revealed that MethaneSAT suddenly went silent on June 20, and its mission operations team has been unable to re-establish contact e

Google’s carbon emissions just went up again

theverge.com Emma Roth 2025-08-22 10:08:04

Google’s carbon emissions jumped yet again as the company continues to push ahead in AI. The company’s 2025 sustainability report emphasizes that its “ambition-based emissions” grew 11 percent last year to reach 11.5 million metric tons of carbon dioxide pollution, marking a 51 percent increase compared to 2019. That puts Google farther away from its goal of slashing planet-heating pollution in half by 2030 compared to a 2019 baseline. But what it calls “ambition-based” emissions excludes certa

Methane Pollution Has Cheap, Effective Solutions That Aren’t Being Used

wired.com Umair Irfan 2025-09-01 18:00:00

This story originally appeared on Vox and is part of the Climate Desk collaboration. Odorless and colorless, methane is a gas that is easy to miss—but it’s one of the most important contributors to global warming. It can trap up to 84 times as much heat as carbon dioxide in the atmosphere, though it breaks down much faster. Measured over 100 years, its warming effect is about 30 times that of an equivalent amount of carbon dioxide. That means that over the course of decades, it takes smaller a

Why Some AI Models Spew 50 Times More Greenhouse Gas to Answer the Same Question

gizmodo.com Natalia Mesa 2025-09-06 13:00:55

Like it or not, large language models have quickly become embedded into our lives. And due to their intense energy and water needs, they might also be causing us to spiral even faster into climate chaos. Some LLMs, though, might be releasing more planet-warming pollution than others, a new study finds. Queries made to some models generate up to 50 times more carbon emissions than others, according to a new study published in Frontiers in Communication. Unfortunately, and perhaps unsurprisingly,

Biofuels Policy, a Mainstay of American Agriculture, a Failure for the Climate

news.ycombinator.com Georgina Gustin 2025-09-13 11:02:22

The American Midwest is home to some of the richest, most productive farmland in the world, enabling its transformation into a vast corn- and soy-producing machine—a conversion spurred largely by decades-long policies that support the production of biofuels. But a new report takes a big swing at the ethanol orthodoxy of American agriculture, criticizing the industry for causing economic and social imbalances across rural communities and saying that the expansion of biofuels will increase greenh

The EPA Wants to Roll Back Emissions Controls on Power Plants

wired.com Molly Taft 2025-09-17 23:36:25

The US Environmental Protection Agency moved to roll back emissions standards for power plants, the second-largest source of CO 2 emissions in the country, on Wednesday, claiming that the American power sector does not “contribute significantly” to air pollution. “The bottom line is that the EPA is trying to get out of the climate change business,” says Ryan Maher, a staff attorney at the Center for Biological Diversity.

What’s driving electricity demand? It isn’t just AI and data centers.

technologyreview.com Casey Crownhart 2025-06-02 20:00:00

Take the US, for example. The IEA report points to other research showing that the 10 states hosting the most data center growth saw a 10% increase in electricity demand between 2019 and 2023. Demand in the other 40 states declined by about 3% over the same period. One caveat here is that nobody knows for sure what’s going to happen with data centers in the future, particularly those needed to run AI. Projections are all over the place, and small changes could drastically alter the amount of en
