  Note: from 1st November 2022 we adopted version 3 of the methodology for estimating CO2 emissions. This will tend to lower CO2 estimates for a given size.

  Tip: Optimise images

  1. carouselmob.jpg?m=17... is 46kB

  First, check that images are appropriately sized - you most likely don't need a 6000x4000 pixel image straight from a digital camera. In Windows, the Photos software will let you quickly shrink huge images and will give you an improvement.

  Next you could try using tinyjpg.com (JPG image) or tinypng.com (PNG image) to further optimise your image. This will strip out metadata that may be taking up lots of space.

  *This is an estimate from Google PageSpeed and you may get much better results than this in practice.

  Tip: Large files

  Aside from images, here are the biggest resources:

  1. durham.js?v=638744286197130000 is 325kB
  2. gtm.js?id=GTM-TLTZTR is 108kB
  3. durham.css?v=638745394969130000 is 98kB
  4. icons.woff is 51kB

  Tip: Limit third-party code

  Here are the largest sources of third-party code:

  1. Google Tag Manager uses 108kB
  2. cassiecloud.com uses 42kB

  Third-party code can significantly impact load performance. Limit the number of redundant third-party providers and try to load third-party code after your page has primarily finished loading.
