Did you know that industrial use of freshwater has increased sixfold over the last century, but the amount available for use remains effectively fixed? While desalination is an option, for most purposes, it’s prohibitively expensive and energy-intensive, leaving industry working with the limited freshwater resources available.

As regulatory bodies and legislators around the world wake up to this fact, the rules around water use and the reporting duties placed on businesses become ever stricter. Traditional methods of measuring water use, based on water withdrawals alone, are no longer detailed enough as they don’t incorporate elements like grey water footprints, environmental effects or the full range of impacts across the life cycle of their products and their usage of freshwater resources.

Life-cycle assessment (LCA) based water footprinting dives deeper than previous methods could. Now we can uncover hidden and indirect environmental impacts across the whole life-cycle of a product, from extraction to disposal. Making effective use of these tools is vital for any company which takes its sustainability efforts and regulatory responsibilities seriously.

Here’s how LCA-based water footprinting can help your sustainability team.

Why Are Businesses Seeking Water-Footprinting From Their LCA Software?

Water is a limited resource and with the demands of industry taking more and more of it, regulators are increasingly pushing for stricter accounting when companies undertake their product life cycle inventory efforts. These requirements sit hand in glove with other environmental impact reporting duties, so it makes sense that companies want software that can handle their water footprinting needs alongside the other life-cycle assessments they’re required to undertake.

Traditionally, the metrics which businesses would focus on when looking at their water consumption were simple: how much fresh water was taken. This gives a very macro-level overview of the sustainability implications of a given operation. For a more detailed, and therefore more actionable, set of insights, more nuance is needed.

LCA-based water footprinting gives this detail, weighing up both the amount consumed and the environmental consequences including impacts on ecosystems, freshwater depletion and human health. This approach, often referred to as the Liquid Resource Analysis Framework, allows sustainability teams to glean actionable insights which can be used to find a balance between operational efficiency and minimizing environmental impacts.

This nuance can be tuned to the basin-specific level, allowing detailed measurements of flow requirements, fresh-water availability, water degradation, and regional water stress. This deeper level of data covering the details of water consumption makes meeting environmental targets easier and allows your team to produce more accurate reports.

Essential Features to Evaluate In Water Footprint LCA

Getting the most from LCA-based water footprinting software requires carefully weighing up the features that your team will need. There are a few standout things that most sustainability professionals will appreciate when calculating both carbon footprint and aquatic life cycle impact assessment work:

  •       Integration With Existing Systems
  •       Automation of Data Input
  •       Compatibility with Compliance Reporting (both current and future)
  •       Ease of Use
  •       Scalability
 

Integration with the existing systems around your supply chain means that data can be drawn directly from the source. This real-time monitoring allows your sustainability team and supply chain managers to pinpoint water usage hotspots on the ground and act quickly to reduce the impacts.

Being well integrated with existing systems across your business also allows your water footprint in LCA software to automatically gather and input the required data into your reports. This not only frees up your team from the cumbersome duty of administration, allowing them to focus on implementing new initiatives, but it vastly reduces the risk of human error creeping into your reports.

The regulatory environment is getting ever more stringent, and there are serious consequences for failing to meet the required standards. It’s important to ensure that your LCA water footprinting software (and LCA systems in general) makes staying compliant as simple as possible. Whether it’s ISO 14040, CSRD, or ensuring your EPDs are in order, how your software helps you stay compliant is a key consideration.  It’s worth placing a premium on systems that have one eye on the future requirements too. 

It’s also important to consider how easy the software is to use. Your sustainability team, supply chain managers, and other stakeholders should ideally be able to glean valuable insights into water usage at a glance through intuitive dashboard displays like those found in Ecochain.

Finally, consider not only your current needs but what you’ll require as your business grows. Look for a service which allows you to scale up or down as required without locking you into cumbersome contracts that may not always meet the needs of your business.
