A digital efficiency audit might not be top of your to-do list, but it should be.
If you haven’t checked under the bonnet of your website lately, it could be quietly draining energy, slowing down users, and even hurting your bottom line or brand.
Most businesses don’t realise it, but poor website performance isn’t just a UX issue anymore—it’s a sustainability one too.
Website performance optimisation isn’t just about shaving seconds off your load time. It’s about creating a faster, leaner, and more energy-efficient digital experience. When your website is bloated, unoptimised, or running on inefficient infrastructure, you’re not just frustrating your users—you’re racking up digital emissions too.
The true cost of poor website performance
We’ve all clicked away from a slow site. When it comes to visitor engagement, every second counts.
But it’s not just conversions you’re losing.
A heavy, underperforming site increases your carbon footprint every single day. The more data your pages require, the more energy is required from data centres to networks and devices. That’s where website carbon emissions start to add up—and fast.
In fact, performance and emissions are often two sides of the same coin. If you reduce website load time, you’re potentially also reducing energy usage and digital waste. That’s why performance-led businesses are increasingly using a digital efficiency audit to uncover hidden problems.
What causes high digital emissions?
Most sites aren’t built to grab the user’s attention and keep them engaged, not necessarily with efficiency in mind. They’re patched together over time, weighed down by plugins, unused scripts, uncompressed images, and outdated third-party tools. Here are a few common culprits:
- Large, unoptimised media files
- Excessive, or even duplicated / redundant third-party scripts and trackers
- Bloated code or themes
- Slow hosting
- Poor caching and no lazy loading
All of these things contribute to poor website performance and higher digital carbon emissions. And they’re usually fixable with a few simple changes.
Why website performance optimisation is now mission-critical
You wouldn’t leave a warehouse light on 24/7 for no reason. But that’s exactly what many businesses are doing digitally. A poorly optimised website is like leaving the taps running all day—it’s wasteful, expensive, yet easy to overlook or say “I’ll fix that later”.
That’s why more teams are starting to treat digital efficiency like any other part of their sustainability or operations strategy. Because when you reduce website load time, you’re improving the user journey, boosting SEO, lowering bounce rates—and cutting digital emissions all at once.1
This isn’t just good for the planet. It’s good for business.
