Researchers chart path for investors to build a cleaner aviation industry
Cutting planet-warming pollution to near-zero will take more than inventing new clean technologies—it will require changing how the world invests in them. That’s especially true for industries like aviation, where developing and adopting greener solutions is risky and expensive, according to a University of California San Diego commentary piece in Science.
The paper calls for smarter ways of managing investment risk that could help speed up the shift toward cleaner air travel and other hard-to-decarbonize sectors.
“The aviation sector—a fast-growing source of greenhouse gases—illustrates the broader challenge of industrial decarbonization: too little investment in technologies that could yield the biggest climate benefits,” said the paper’s co-author David G. Victor, professor of innovation and public policy at the UC San Diego School of Global Policy and Strategy and co-director of the Deep Decarbonization Initiative.
The piece outlines a new approach that could help guide a coalition of research and development (R&D) programs alongside investors and airlines seeking to deploy new technologies to curb carbon emissions from the aviation industry.
“Despite all the chaos in global geopolitics and climate policies these days, there are large and growing pools of capital willing to take risks on clean technology,” Victor said. “What’s been missing is a framework to guide that capital to the riskiest but most transformative investments.”
He added that investors and research managers tend to focus on familiar, lower-risk projects like next-generation jet engines or recycled-fuel pathways.
“But getting aviation and other hard-to-abate sectors to near-zero emissions means taking on bigger risks with technologies and new lines of business that will be highly disruptive to the existing industry. Investors and airlines need to find smarter ways to encourage and manage these disruptive investments,” Victor said.
In the article, Victor and co-authors call for a more realistic framework to guide both research funding and private investment.
They propose a tool called an Aviation Sustainability Index (ASI)—a quantitative method to assess how different technologies or investments could help decouple emissions from growth in air travel.
The approach is designed to help investors distinguish between projects that only modestly improve efficiency and those that could significantly transform the sector’s climate impact.
The authors note that while roughly $1 trillion is expected to flow into aviation over the next decade, most of that money will simply make aircraft slightly more efficient. Few investors, they argue, have clear incentives to back the kind of breakthrough technologies—such as hydrogen propulsion, advanced aircraft designs, or large-scale sustainable fuel systems—that could substantially reduce emissions.
“Cleaner flight is possible, but it requires changing how we think about both risk and return,” Victor said. “We need new institutions, incentives, and partnerships that reward innovation, not just incrementalism.”
The commentary, written by a multinational team of scholars, also highlights a broader lesson for climate policy: global decarbonization goals such as “net zero by 2050” sound bold and ambitious. But when it becomes clear that they can’t be met, these goals make it harder to focus on the practical steps needed today to drive change in real-world markets.
Ultimately, the paper argues for action that begins now. By developing better tools to evaluate climate-friendly investments and by rewarding companies willing to take calculated risks on breakthrough technologies, governments, investors and industry leaders can accelerate real progress toward decarbonization.
The paper was co-authored by Thomas Conlon of University College Dublin, Philipp Goedeking of Johannes Gutenberg University of Mainz (Germany) and Andreas W. Schäfer of University College London.

The Best Chromebooks Are Doing Their Best to Course Correct
I was delighted to see that the Acer Chromebook Plus 516 didn’t skimp on a crappy touchpad. That goes a long way toward improving the experiencing of actually using the laptop on a moment-by-moment basis. I wasn’t annoyed every time I had to click-and-drag or select a bit of text. This one’s biggest weakness is definitely the screen, which is true of just about every cheap Chromebook I’ve tested. The colors are ugly and desaturated, giving the whole thing a sickly green tint. It’s also not the sharpest in the world, as it’s stretching 1920 x 1200 pixels across a large, 16-inch screen. But in terms of usability and performance, the Acer Chromebook Plus 516 is a great value, combining an Intel Core i3 processor with 8 GB of RAM and a 128 GB of storage. For a Chromebook that’s often on sale for $350, it’s a steal.
While we’re here, let’s go even cheaper, shall we? Asus has two dirt-cheap Chromebooks that I tested last year that I was mildly impressed by. The Asus Chromebook CX14 and CX15. Notice in the name that these are not “Chromebook Plus” models, meaning they can be configured with less RAM and storage, and even use lower-powered processors. That’s exactly what you get on the cheaper configurations of the CX14 and CX15, which is how you sometimes get prices down to as low as $130. I definitely recommend the version with 8 GB of RAM, but regardless of which you choose, the both the CX14 and larger CX15 are mildly attractive laptops. You’d know that’s a big compliment if you’ve seen just how ugly Chromebooks of this price have been in the past.
With these, though, I appreciate the relatively thin bezels and chassis thickness, as well as the larger touchpad and comfortable keyboard. The CX15 even comes in a striking blue color. The touchpad isn’t great, nor is the display. Like the Acer Chromebook Plus 516, it suffers from poor color reproduction and only goes up to 250 nits of brightness. It only has a 720p webcam too, which makes video calls a bit rough. But that’s going to be true of nearly all the competition (and there isn’t much).
Of the two models, I definitely prefer the CX14 though, as it doesn’t have a numberpad and off-center touchpad, which I’ve always found to be awkward to use. Look—no one’s going to love using a computer that costs the less than $200, but if it’s what you can afford, the Asus Chromebook CX14 will at least get you by without too much frustration.
Whatever you do, don’t just head over to Amazon and buy whatever ancient Chromebook is selling for $100 for your kid. It’s worth the extra cash to get something with better battery life, a more modern look, and decent performance.
Other Good Chromebooks We’ve Tested
We’ve tested dozens and dozens of Chromebooks over the past years, having reviewed every major release across the spectrum of price. Unlike Macs and Windows laptops, Chromebooks tends to stick around a bit longer though, and aren’t refreshed as often. I stand by my picks above, but here are a few standouts from our testing that are still worth buying for the right person.

Blackbox replaces two racks of HPE storage with 8U of Everpure | Computer Weekly
Service provider Blackbox Hosting has consolidated storage from two full racks down to just 8U of rack space following migration to Everpure FlashArray hardware. The move has allowed the provider to deliver “sovereign” cloud services with a 10:1 data reduction ratio and an 85% reduction in power utilisation.
Blackbox Hosting evolved over 14 years from a single rack to supporting more than 1,500 virtual machines (VMs), and has datacentre capacity at Canary Wharf with a secondary site in Slough.
The company operates a fully managed, sovereign (see box) model for major software suppliers including Iris Software Group, which supports payroll and financial management for approximately 60% of UK academies.
Blackbox previously relied on HPE 3PAR 8400 all-flash arrays. However, as the hardware approached end-of-life, the company faced mounting challenges.
“Support renewal costs were significant, and we had issues with HPE support,” said Matthew Burden, CEO at Blackbox Hosting. “We had a power supply failure in a DR site, and despite a four-hour SLA [service-level agreement], it took nearly two weeks to replace. They also began charging for firmware updates that were previously included.”
The 3PAR environment was cumbersome, said Burden, and required two full racks of hardware to manage the company’s near-petabyte scale.
When it looked for a more performant and dense alternative, Blackbox turned to Pure Storage, which recently rebranded as Everpure.
High density; ‘one-second’ RPO
Blackbox has deployed a range of Pure Storage FlashArray models across its two datacentres to support its active-passive high-availability design.
The deployment includes two FlashArray//X50 R3s, two X50 R4s, and two FlashArray//C20 units for file clusters.
The hardware supports predominantly Hyper-V and VMware VMs, running 90% Windows-based workloads, primarily SQL Server, plus Linux servers.
The transition from 3PAR to Pure has seen a dramatic consolidation of physical space. “We went from two entire racks filled with disks to two 4U boxes,” said Burden. “Our total provisioned storage is 998TB and we get a total reduction of 10:1. 3PAR had deduplication, but not compression on SSDs.”
Beyond space savings, the disaster recovery (DR) capabilities have seen a massive upgrade. Previously, the company’s recovery point objective (RPO) was limited to 15 minutes. “With Pure Storage, it is one second,” said Durden. “We replicate all 1,500 VMs to our backup datacentre. For a customer with 1,000 VMs, we can spin those up for quarterly testing and they are only one second out from live data.”
Performance and sustainability
The shift to non-volatile memory express-based flash has also provided a significant boost to the provider’s green credentials. Sustainability reports generated via Pure’s Evergreen dashboard show an 85% saving in power utilisation compared with the legacy HPE environment.
For the end users – which include major corporate energy, finance and transport organisations – the benefit is felt in application speed. “We’ve had clients with huge databases that were always slow with previous providers,” said Justin Field, commercial director at Blackbox. “They can pull data significantly faster now, which is a big play for us when competing against hyperscalers.”
Burden also highlighted the “zero-touch” operational simplicity of the new arrays. “The older arrays were very cumbersome; you had to know exactly what you were doing,” he said. “The Pure web interface is very simple, which makes the operational side much easier. Plus, with Evergreen, we don’t have to pull arrays out for upgrades. We can just put in new controllers as scale increases.”
