Carbon Footprint of Websites in Singapore
What We Found After Auditing 564 Sites
Climate UX conducted an independent audit of 564 corporate websites across Singapore and beyond, measuring the carbon emissions generated by each page load. The findings reveal a significant and largely invisible environmental cost embedded in everyday digital infrastructure — and a clear opportunity to fix it.
Key findings from the research:
-
The average corporate website emits 11.35g of CO2 per page view
-
One website in our audit produced 161g of CO2 per visit — equivalent to driving 1km every time someone loads the homepage
-
There is a 400x difference between the cleanest and worst-performing websites audited
-
Green hosting alone reduces emissions by 58%
-
42% of website emissions sit in the product layer, not hosting — meaning design and code decisions matter as much as infrastructure
-
Simple fixes (image compression, code cleanup, green hosting) can cut a site's carbon footprint by 60–80% within days
