The environmental impact of the tech industry is well documented, but Lenovo is taking steps to limit its carbon contribution. A wide-ranging portfolio of new devices for 2022 includes the new Slim 9i (also known as Yoga Slim 9i), the first laptop ever to receive carbon-neutral certification.

Essentially, this means all carbon emissions associated with the production of the device have been offset in other ways. Lenovo has its own CO2 Offset Service, which focuses on improving renewables and reducing air pollution. Via a range of projects, Lenovo says you can offset the emissions released during manufacturing, shipping and up to five years of usage. Other laptops may be called carbon neutral, but this is the first time one has been certified by a trustworthy third-party such as TÜV Rheinland.

It’s the latest step in Lenovo’s sustainability efforts, which already focus on creating more durable products from recycled materials and limiting emissions at every step of the process. In the case of the Slim 9i, specs suggest the quality of the product is still high.

Performance is still a priority, with Intel’s latest 12th-gen CPUs (i5 or i7) joined by Iris Xe integrated graphics and 16- or 32GB of DDR5 RAM. This helps power a 14in OLED display, with a choice between 4K at 60Hz or 2.8K (2880x1800) at 90Hz. Both support touch input and have low blue light certification.

You also get a generous 75Wh battery, which Lenovo says will last for up to 15 hours of 1080p video playback. When you do run out of charge, just 15 minutes connected to the power supply is - apparently - enough for another two hours of use.

Other features of note include a 1080p webcam (with Windows Hello support), quad Bowers & Wilkins speakers and a 512GB or 1TB SSD. However, at just 14.9mm thick, ports do take a hit. All three USB-C slots can be used for charging and support Thunderbolt 4, but a 3.5mm headphone jack is the only other connection.

You’ll also need deep pockets if a sustainable laptop is what you're after. The Lenovo Slim 9i will start at $1,799 (approx. £1,439) in the US when it’s released in June 2022. International pricing and availability is yet to be revealed.

New Slim Pro X line

Most of Lenovo’s 2022 laptops are iterative updates to existing products, but there’s one key exception. The Slim 7 Pro X and Slim 7i Pro X are brand-new devices, aiming to deliver top-tier performance without compromising on portability.

Both feature a 14.5in, 3K (3072x1920) LCD display, complete with 120Hz adaptive refresh rate and a 16:10 aspect ratio. The main difference can be found internally, where the Slim 7 uses AMD processors while the Slim 7i opts for Intel. These are from the performance-focused lines of the Ryzen 6000 Series and 12th-gen Alder Lake respectively, and combine with 16- or 32GB of DDR5 RAM.

But a key reason to buy either is the GPU, where most slimline laptops opt for integrated graphics. That’s still the case on entry-level models, but you also have the option for a discrete Nvidia GTX 1650 or RTX 3050 graphics card.

Despite only being 15.9mm thick, you get a far greater range of ports than the Slim 9i. On the Slim 7, that’s 2x USB-C, 2x USB-A and a 3.5mm jack. The Slim 7i drops one of the USB-A ports, but you get a full-size HDMI instead.

However, these aren't exactly cheap either. Prices start at $1,499 (approx. £1,200) for the Slim 7 Pro X and $1,699 (approx. £1,360) for the Slim 7i Pro X when they become available in June 2022. Again, we don’t know international pricing and availability at this stage.

The new Slim 7i Carbon is one of the lightest laptops you can buy, but the regular Slim 7 and Slim 7i offer everything most people are looking for. There’s also a new 16in model of the Slim 7, plus a Yoga 7 convertible and Yoga AIO 7 desktop computer.

All the laptops are contenders for our overall laptop chart, although they're also aimed at business customers.
