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.

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.
