The Environmental Cost of ROT Data: What Organisations Need to Know

Redundant, Obsolete and Trivial data (ROT) is a persistent issue often discussed in terms of compliance and risk – but what about its environmental impact?

Cheaper and more accessible cloud storage, while enormously convenient for business, has amplified the the environmental impact. The reality is that all this cheap and readily available data capacity in the cloud has reduced the urgency we used to all feel in needing to actively manage information (remember when you had to delete items on your local disk to make space for new ones?).

As a result, many organisations in the UAE now retain far more data than they need, for far longer than necessary.

The Sustainability Impact

What’s the actual impact? Unsurprisingly, digital ROT consumes vast amounts of energy, cooling and maintenance in data centres. These facilities account for an estimated 1 to 1.5 percent of global electricity use (and growing fast). Every redundantly retained file contributes to this global overhead, whether storage is on‑premises or in the cloud (it’s still a disk somewhere!).

Electricity consumption isn’t the end of it though; the manufacture, maintenance and disposal of storage media carries a huge cost if not handled properly. IT waste disposal is therefore another environmentally impactful process we need to tack on, and we’ve written about the shadow IT creep impact before. All in all, having a huge storage footprint of which perhaps only half is necessary, isn’t sustainable.

Physical ROT

Physical ROT, including paper records, obsolete devices and legacy media, requires physical storage space, climate control and eventual disposal. If not handled responsibly, this can contribute significantly to landfill waste and environmental impact. Paper records stored in offsite facilities incur an indirect emissions footprint that’s not always clearly understood.

Financial and Compliance Impact

Finally, the financial implications are equally clear. Cloud storage fees accumulate over time, and physical storage contracts often run for years. Staff productivity is reduced when employees must search through irrelevant or outdated material to find what they need.

As mentioned earlier, the compliance perspective is also impacted by ROT. Retaining personal data beyond its required retention period can breach data protection and retention regulations, which requires data be kept only as long as necessary.

Best Practice: Reducing ROT 

Here’s a six-step approach we created, that organisations can follow when beginning a ROT reduction programme:

1. Inventory and baseline: Identify all digital and physical information holdings. Quantify storage volumes, associated costs and estimated energy use.
2. Retention Policy alignment: Ensure retention schedules are compliant and enforced through automated rules where possible, as human error is a common cause of over-retention.
3. Secure destruction: Apply recognised standards such as ISO/IEC 21964 for secure destruction. Reputable providers will issue certificates of destruction for audit purposes.
4. Targeted digitization: Digitize only what is necessary. Many organisations do not need to digitise everything in their archives.
5. Lifecycle Management: Use automated policies to move data to lower‑cost, lower‑energy storage tiers or securely delete it when not needed.
6. Ongoing Monitoring: Track progress against baseline metrics (we can help here) and incorporate environmental metrics where possible.

What Does this Look Like in Practice? 

To illustrate, consider a hypothetical example based on typical projects.

An organisation implements a ROT reduction programme and removes thousands of boxes of paper records, retires legacy systems, and deletes large volumes of unnecessary digital data.

The result is reduced storage costs, faster information retrieval, and a measurable reduction in environmental impact. At the same time, compliance is strengthened by ensuring only relevant and required information is retained.

How We Can Help

Reducing ROT is not just about sustainability — it also improves efficiency, reduces costs, and strengthens compliance. Services such as data clean-up, secure destruction, and structured digitisation can support organisations in taking a practical, phased approach to better information management.
