  CO2 estimatePage size

  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

  We estimate potential to save at least 134kB* by optimising images:

  1. Kingston_2025_RBK_We... is 913kB
  2. image__9__1.png is 787kB
  3. Web_Banner_JLHWS_202... is 765kB and could be 78kB smaller
  4. Copy_of_Canbury_gard... is 605kB
  5. Residents_Newsletter... is 458kB and could be 57kB smaller
  6. Carousel_Web_banner_... is 65kB

  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. gtm.js?id=GTM-57VJDBT is 105kB
  2. site-logo-white.svg is 70kB
  3. site-logo.svg is 69kB
  4. icons.data.svg.css?v=3.15.1 is 40kB

  Tip: Limit third-party code

  Here are the largest sources of third-party code:

  1. Google Tag Manager uses 105kB
  2. Google CDN uses 31kB
  3. Google Fonts uses 38kB

  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.
