The untapped potential of existing assets in the Net Zero journey

Why can’t the path to Net Zero be built on replacement alone?

The race to net zero is often described in terms of what comes next: new energy systems, technologies, infrastructure and ways of producing and consuming energy. But another, less discussed question is just as important: what happens to everything we already have?

Across industries, millions of industrial assets are already operating in factories, processing plants, power facilities and vessels around the world. Many have years, sometimes decades, of useful life ahead of them. The question is not simply whether these assets should eventually be replaced, but whether we are making the most of them while they remain in operation.

The transition cannot happen overnight
Industrial assets are designed to operate for long periods, often within complex systems where replacing one component can affect an entire process. Replacement also carries an environmental footprint: new materials must be extracted and processed, components manufactured and transported, and equipment installed and commissioned.

This does not mean replacement should never happen. New technologies will be essential to achieving deeper decarbonization. However, a net-zero strategy focused only on replacing existing equipment risks overlooking a powerful opportunity: improving the performance of the installed base.

The sustainability question therefore needs to evolve from “What should we replace?” to “How much more value can we responsibly extract from what we already have?”

Efficiency does not end when an asset is installed
An asset’s environmental impact is not determined at the moment it is purchased. Its performance throughout its lifetime matters just as much. Equipment can gradually lose efficiency because of wear, fouling, changing operating conditions, outdated configurations or inadequate maintenance. Even relatively small performance losses can become significant when an asset operate continuously for years.

This is particularly relevant as Alfa Laval’s 2025 Sustainability Report identifies the downstream use phase of its products as its largest source of Scope 3 emissions. The report also highlights the importance of ensuring that products already installed at customer locations continue to function optimally, alongside upgrades and improvements in energy efficiency.

This changes the role of service. It is not simply about fixing something when it breaks. It is about helping assets maintain performance, adapt to changing requirements and deliver value for longer.

Maintenance can be a decarbonization lever
Maintenance is traditionally associated with reliability, uptime and avoiding unexpected failures. Those remain fundamental, but maintenance also has an important role in resource efficiency. When equipment operates efficiently, it can require less energy and fewer resources to deliver the same output. When it is maintained properly, its useful life can potentially be extended. And when components can be repaired or upgraded rather than an entire asset replaced, material consumption and associated environmental impacts can be avoided.

The Sustainability Report notes that properly serviced Alfa Laval products typically have a lifespan of two or more decades and can often be cleaned online (remotely), repaired and upgraded to optimize performance and extend their useful life. In this context, service becomes more than an operational activity; it becomes part of a broader circular economy approach.

Circularity starts long before recycling
Circularity is often associated with what happens at the end of a product’s life: recycling materials, recovering components or finding ways to reuse products. Those activities matter, but one of the most valuable circular interventions can happen much earlier: keeping an asset in productive use for longer.

Every additional year that an industrial asset operates effectively can help defer the resource and environmental costs associated with producing a replacement. This is why durability, repairability, upgradeability and maintenance belong in the same sustainability conversation as recycling.

A circular industrial economy is not only one that recycles more. It is one that makes better use of what it has already produced.

The next phase of Net Zero will be about optimization

The industrial transition will require new technologies, but technology alone will not deliver net zero. Industry must also take a more intelligent approach to the assets already operating today.

That means looking at the entire lifecycle, from installation and maintenance through optimization, upgrades, reuse and eventual end of life. It means recognizing that every asset has an embedded material and energy footprint, as well as an opportunity to deliver value for longer.

The net-zero transition presents two simultaneous tasks: build what the future requires and make better use of what we already have. The road to Net Zero will be built with new technology, but it will also be shaped by how intelligently we manage what already exists.
