  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 233kB* by optimising images:

  1. winter_2025_website_... is 1.1MB and could be 198kB smaller
  2. GardenWasteSubscript... is 208kB
  3. river_view_2.jpg is 112kB
  4. council_plan_montage... is 93kB
  5. ebilling_mobile_devi... is 66kB and could be 16kB smaller
  6. reciteme_button%20(1... is 52kB
  7. EmailScreen.jpg is 47kB
  8. money_advice_piggy_b... is 40kB and could be 6.6kB smaller
  9. HomePage_Idling.jpg is 33kB and could be 4.4kB smaller
  10. fostering_parent_and... is 33kB and could be 8.8kB smaller

  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: Limit third-party code

  Here are the largest sources of third-party code:

  1. Google CDN uses 31kB
  2. freeprivacypolicy.com uses 58kB
  3. Recite Me uses 52kB
  4. Google Fonts uses 31kB

  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.
