Data centers can be likened to an ecosystem of computing facilities that contain many facets required to store and handle data. IDTechEx's latest report, "Sustainability for Data Centers 2025-2035: Green Technologies, Market Forecasts, and Players", unpacks efforts being made in the data center sector towards increased sustainability in response to the rising CO2 emissions from the development of AI.

As the United States withdraws from the 2015 Paris Agreement, which established globally shared goals that pledged to contribute to reducing greenhouse gas emissions, concerns about the future of sustainable technologies are growing. However, IDTechEx identifies key areas where sustainable growth can remain a reality.

Key trends are emerging that suggest where the second-life battery market will develop and what applications these technologies will be used for. As written in their recently updated market report, "Second-life Electric Vehicle Batteries 2025-2035: Markets, Forecasts, Players, and Technologies", IDTechEx predicts that by 2035, the global second-life EV battery market will be valued at US$4.2 billion.

Germany has one of the strongest battery energy storage systems (BESS) potential worldwide, with an already large uptake of residential battery storage, meaning market growth is set to succeed within the next decade.

Public awareness of PFAS (per- and polyfluoroalkyl substances) is hitting a new high as headlines concerning "forever chemicals" continue to appear in prominent news outlets. Whether it be news about PFAS bans in different industries, lawsuits against PFAS manufacturers and users, detection of PFAS in various locations and products, and treatment of PFAS in drinking water, there is no doubt that for many, PFAS is one of the foremost health issues of the 2020s.

The advancement of fuel cell technologies, combined with the global commitment to sustainable aviation, creates a significant opportunity for hydrogen-fuelled planes to enhance the sustainability of air travel.

Silicon-based solar technologies continue to dominate the market; however, there is rising interest in an emerging technology known as perovskite. Perovskites have the potential to enhance existing silicon solar supplies, but which applications can perovskite solar be used for, and how will it compete in a market dominated by an already well-established technology?

IDTechEx forecasts that by 2035, the global data center sector will have saved US$150 billion by using low-carbon energy sources compared to a fossil fuel scenario (taking 2024 as the baseline). Some emerging energy technologies expected to play an increasingly important role are explored in this article.

As growing numbers of countries identify critical materials within their economies, the ability to recycle them is becoming increasingly important, especially considering both their economic importance and ongoing supply risks. Sustainability goals rely on growing technology sectors like electric vehicles, which rely on magnets to be manufactured, ultimately meaning sourcing and recycling critical materials is an economic necessity to keep supply chains running.
