Who We Are.

Our digital lives create more C02e than the whole aviation industry put together (Source: Lancaster University), and now is the time to act.

Green Clicks is the internet's early warning 🔔 system, helping major websites and apps to dramatically reduce their digital emissions through research, insights, and advice.

Methodology: User digital emissions have been measured per megabyte using the ACEEE findings of 5kWh utilisation per gigabyte of data, alongside EIA guidance of 0.38782148kg (0.855 Pounds) C02e emissions per KWh (focusing on US citizens only). For fairness - infinite scroll websites have all been capped to a sequence of three scrolls, cookies accepted, and no platforms are logged into for this dataset above, or any previous caching. Related device energy usage is not included (i.e. the electricity used to power a screen, or company server external to the user). All resource loads were collected (uncompressed) using DevTools

Top Questions

Your top questions answered:

We work with a large array of tools, consultants, and developers to perform reductions in your website emissions. For some websites - it is merely a few basic changes to reduce website load times and therefore emissions, but for others it can mean entirely replatforming what they have, sadly - not forgetting the efforts needed to reduce server emissions.

It is best to start by utilising both lab based and in-field online tools that can analyse your website for speed and performance. From there you will be able to understand what is needed to your reduce website load times and therefore website emissions. It is always best to consult with an expert on this.

We have a wide number of voluntary and paid roles to assist Green Clicks in measuring, and tackling online emissions from the largest emitters online. Get in touch to find out more.
