Website Decarbonisation

Reduce Website Carbon Without Rebuilding

Improve the Website You Already Have

Website decarbonisation reduces your website’s carbon footprint for a cleaner, more efficient website. Performance improvements can include faster loading, stronger security, better search visibility and a smoother user experience.

WEBSITE DECARBONISATION EXPLAINED

What Is Website Decarbonisation?

Improve the Website You Already Have Across Carbon and Performance

Website decarbonisation is the process of improving an existing website so it uses fewer digital resources, produces lower estimated carbon emissions and performs more effectively.

It retains the parts of the website that still have value while improving areas such as speed, efficiency, security, reliability, search visibility, user journeys and conversion potential.

The result is a cleaner, faster and more effective website with a longer useful life.

MEASURED RESULTS

Website Decarbonisation That Delivers Measurable Improvement

Real projects. Real reductions. Measured against the starting point.

91% reduction in website carbon emissions

A substantial reduction in estimated website carbon output following targeted decarbonisation and performance improvements.

73% reduction in website carbon emissions

A major reduction in estimated carbon output while improving the efficiency and performance of the existing website.

Measured, Not Assumed

We Benchmark Before and After

Each decarbonisation project starts with a clear baseline. Once the agreed improvements are complete, we retest the website and compare the results against the original version.

That allows us to show measurable changes in areas such as carbon output, page weight and website performance.

WEBSITE CARBON & PERFORMANCE CONSULTANCY

Find the Right Path Forward Before You Commit to Change

Decarbonisation starts with understanding what your website actually needs.

We assess your website’s carbon output, performance and technical condition before recommending significant work. The right route may be targeted improvement, website decarbonisation, a pay monthly replacement or bespoke website development.

HOW WEBSITE DECARBONISATION WORKS

From Baseline Testing to Measured Improvement

Measure. Assess. Test. Improve.

1

Establish the Baseline

Measure the website’s current carbon and performance position before any changes are made.

2

Assess Technical Viability

Review the website and test selected early improvements to establish what level of change may realistically be possible.

3

Decide the Right Route

Use the findings to decide whether a wider decarbonisation project is worthwhile or whether another route would make more sense.

4

Decarbonise and Re-Test

Where the website proves viable, begin the decarbonisation process and re-test the website to measure the results against the original baseline.

The level of improvement depends on the existing website and cannot be guaranteed before assessment and testing.

AFTER DECARBONISATION

Keep Carbon and Performance Under Control

Ongoing management and monitoring help protect the improvements over time.

Track

Monitor carbon and website performance over time to identify drift, regression and emerging issues.

Maintain

Keep the website secure, updated and technically maintained so the gains from decarbonisation are protected.

Evidence & Report

Provide clear carbon and performance reporting for internal, sustainability and ESG use.

Common Questions

Website Decarbonisation FAQs

Website decarbonisation improves an existing website to reduce estimated carbon output while strengthening speed, efficiency, usability and search visibility.

In principle, most websites can be improved. However, decarbonisation is not always technically or commercially viable.

Older platforms, outdated technology, poor construction or significant technical limitations can make improvement disproportionately expensive. In those cases, investing the same budget in a new ultra-low-carbon, high-performance website may deliver better long-term value.

Our consultancy process assesses the website’s condition, improvement potential and likely costs, helping you decide whether to decarbonise the existing website or invest in a new one.

Not necessarily. Where the design, content and functionality still work well, they can often be retained while the website is improved behind the scenes.

The website is assessed before work begins and tested again after delivery, allowing changes in carbon output, performance and wider website quality to be compared.

Ongoing monitoring and management can help maintain performance, identify drift and provide evidence of continued improvement.
