The truth about website carbon
The technology sector is responsible for about 4% of global greenhouse gas emissions. Carbon awareness and measurement matter so we can collectively drive change. But what actually causes website carbon emissions, and how do you fix it? The answer is website efficiency. Lighter, more efficient websites not only cut carbon emissions but also improve performance and lower infrastructure costs!

Fix the root cause of website carbon
Boost performance and cut costs while you're at it
Your carbon score is a starting point. The Website Efficiency & Sustainability Audit provides a clear view of how your website impacts carbon emissions, performance, and costs. Our consultant-led audit includes:
• Detail on what's driving carbon, performance and costs
• A report that IT leaders and board members will love
• Prioritised recommendations tied to your goals
• Implementation-ready plan designed for growth

How our calculator works
Built on the Green Web Foundation's trusted methodology, the calculator reveals more than emissions. It uncovers the inefficient code that simultaneously increases your carbon footprint, inflates infrastructure costs, and hurts performance.
