This website is run by Ricardo Energy and Environment. We want as many people as possible to be able to use this website. The website is mostly complinance with Web Content Accessibility Guidelines (known as WCAG 2.1), which is an internationally recognised set of recommendations for improving web accessibility. For example, that means you should be able to:

  • zoom in up to 300% without the text spilling off the screen
  • navigate most of the website using just a keyboard for browser Chrome and IE, partially for Firefox
  • navigate most of the website using speech recognition software 
  • listen to most of the website using a screen reader
  • the contrast of the page and front size can be changed by change the setting of window of computer

We know some parts of this website are not fully accessible:

  • you cannot modify the line height or spacing of text
  • most older PDF documents are not fully accessible to screen reader software
  • the data plots do not have description on pollution overview page, but the data for each graph are accessible either via link or in a table
  • mapping content have no full descriptions
  • you cannot skip to the main content when using a screen reader and keyboard
  • there’s a limit to how far you can magnify the map on pollutant emission page, but large scale of maps have been provided.

Enforcement procedure

The Equality and Human Rights Commission (EHRC) is responsible for enforcing the Public Sector Bodies (Websites and Mobile Applications) (No. 2) Accessibility Regulations 2018 (the ‘accessibility regulations’).

Technical information about this website’s accessibility

Ricardo Energy and Environment is committed to making its website accessible, in accordance with the Public Sector Bodies (Websites and Mobile Applications) (No. 2) Accessibility Regulations 2018.

This website is partially compliant with the Web Content Accessibility Guidelines version 2.1 AA standard, due to the exemptions listed below:

There’s no way to skip the repeated content in the page header (for example, a ‘skip to main content’ option).

It’s not possible for users to change text size without some of the content overlapping.

Interactive tools and transactions

Some of our interactive forms are difficult to navigate using a keyboard in Firefox.

We’ve assessed the cost of fixing the issues with navigation and accessing information, and with interactive tools and transactions. We believe that doing so now would be a disproportionate burden within the meaning of the accessibility regulations. We will make another assessment when the supplier contract is up for renewal,  which is likely to be in 2025.

Content that’s not within the scope of the accessibility regulations

Some of our PDFs and Word documents are essential to providing our services. For example, we have PDFs with information on how users can access our services, and forms published as Word documents.  We have started to use high contrast colours in the map images, and plan to using html format in the future (2022).

The accessibility regulations do not require us to fix PDFs or other documents published before 23 September 2018 . We do not plan to replace existing documents published pre 2021. Any new PDFs or Word documents we publish will meet accessibility standards.

How we tested this website

We use the Web Content Accessibility Guidelines V2.1 level AA to test how accessible this is. We used Government recommended software tested all the pages, as well as manual test for keyboard navigation and screen reader.
