Enterprise technology emits as much carbon as the United Kingdom. There are quick ways to fix that.

There’s a hidden source of carbon pollution hiding right under companies’ noses.

Enterprise technology is often out of sight, out of mind. So, too, are its carbon emissions, which is why industry leaders have been slow to mitigate its climate toll despite the fact that enterprise technology emits as much carbon as the United Kingdom does.

The sector emits between 350 and 400 megatons of carbon dioxide equivalent gases (a metric used to measure all greenhouse gases and standardize them to carbon dioxide), which amounts to roughly 1% of total global greenhouse gas emissions, according to a new analysis from McKinsey.

While data centers’ energy use often grabs headlines, McKinsey found that personal business technology such as laptops, smartphones and even printers contribute up to two times more to the sector’s carbon emissions.

The report covers emissions solely resulting from a company’s own on-site enterprise operations and the indirect emissions resulting from end user devices that the company relies upon; it excludes those from technology that the company is selling to customers, be that in the form of data center capacity or operational devices.

While a single server emits far more carbon than a single laptop on average, enterprise operations have more smartphones and laptops than servers. And these end user devices are replaced more often, adding to their carbon footprint.

Personal tech emissions are largely tied to manufacturing and upstream transportation before the items reach employees, as well as from disposal once they are retired. And these emissions are on track to increase nearly 13% per year between now and 2026.

The use of enterprise technology in the communications, media and services sectors results in particularly high emissions, coming in between 80 and 85 megatons of carbon dioxide equivalent. And banking and investment services is not far behind, with its use of enterprise technology resulting in between 60 and 65 megatons of carbon dioxide equivalent.

CIOs and other enterprise leaders have a few solutions at their disposal to address this mounting problem, and they come at minimal cost. In fact, between 50% and 60% of end user device-related emissions can be minimized by changing how they are sourced, such as by buying fewer devices per person. McKinsey also recommended that enterprise leaders expand device recycling practices. And when it comes to data center-related emissions, McKinsey suggests companies migrate workloads to the cloud, given that “hyper-scalers and colocators are investing significantly in becoming greener.”

The report also recommends that enterprise leaders establish metrics for “green returns” on technology costs, focusing on the cost per ton of carbon saved as they consider suppliers and manufacturers of the technology that their operations rely on. To make the most of this approach, companies first need an established baseline performance in order to gauge how their emissions evolve over time. While tracking every element of a company’s carbon footprint can be an onerous and time-consuming task, McKinsey recommends that enterprise leaders prioritize those elements that have the biggest climate impact, such as the number of laptops purchased.

Careful tracking can ensure that companies make brisk and impactful changes, which is exactly what’s needed to turn the tide on the climate crisis. While many of these will take several years to result in substantial and long-term reductions, the report finds that there is some low-hanging fruit. For instance, promptly taking steps like buying fewer devices in the first place can reduce a company's enterprise-related emissions by up to 20% in a single year.


Inside Amazon’s free video strategy

Amazon has been doubling down on original content for Freevee, its ad-supported video service, which has seen a lot of growth thanks to a deep integration with other Amazon properties.

Amazon’s streaming efforts have long been all about Prime Video. So the company caught pundits by surprise when, in early 2019, it launched a stand-alone ad-supported streaming service called IMDb Freedive, with Techcrunch calling the move “a bit odd.”

Nearly four years and two rebrandings later, Amazon’s ad-supported video efforts appear to be flourishing. Viewership of the service grew by 138% from 2020 to 2021, according to Amazon. The company declined to share any updated performance data on the service, which is now called Freevee, but a spokesperson told Protocol the performance of originals in particular “exceeded expectations,” leading Amazon to increase investments into original content by 70% year-over-year.

Great products are built on strong patents

Experts say robust intellectual property protection is essential to ensure the long-term R&D required to innovate and maintain America's technology leadership.

Every great tech product that you rely on each day, from the smartphone in your pocket to your music streaming service and navigational system in the car, shares one important thing: part of its innovative design is protected by intellectual property (IP) laws.

From 5G to artificial intelligence, IP protection offers a powerful incentive for researchers to create ground-breaking products, and governmental leaders say its protection is an essential part of maintaining US technology leadership. To quote Secretary of Commerce Gina Raimondo: "intellectual property protection is vital for American innovation and entrepreneurship.”

Wall Street is warming up to crypto

Secure, well-regulated technology infrastructure could draw more large banks to crypto.

Technology infrastructure for crypto has begun to mature.

Despite a downturn in crypto markets, more large institutional investors are seeking to invest in crypto.

One factor holding them back is a lack of infrastructure for large institutions compared to what exists in the traditional, regulated capital markets.

How I decided to go all-in on a federal contract — before assignment

Amanda Renteria knew Code for America could help facilitate access to expanded child tax credits. She also knew there was no guarantee her proof of concept would convince others — but tried anyway.

After the American Rescue Plan Act passed in March 2021, the U.S. government expanded child tax credits to provide relief for American families during the pandemic. The legislation allowed some families to nearly double their tax benefits per child, which was especially critical for low-income families, who disproportionately bore the financial brunt of the pandemic.

This carbon capture startup wants to clean up the worst polluters

The founder and CEO of point-source carbon capture company Carbon Clean discusses what the startup has learned, the future of carbon capture technology, as well as the role of companies like his in battling the climate crisis.

Carbon Clean CEO Aniruddha Sharma told Protocol that fossil fuels are necessary, at least in the near term, to lift the living standards of those who don’t have access to cars and electricity.

Carbon capture and storage has taken on increasing importance as companies with stubborn emissions look for new ways to meet their net zero goals. For hard-to-abate industries like cement and steel production, it’s one of the few options that exist to help them get there.

Yet it’s proven incredibly challenging to scale the technology, which captures carbon pollution at the source. U.K.-based company Carbon Clean is leading the charge to bring down costs. This year, it raised a $150 million series C round, which the startup said is the largest-ever funding round for a point-source carbon capture company.
