CAT's free information service offers advice and information on all aspects of sustainable living. Every week we answer hundreds of enquiries by mail, phone and email. We can help you choose what measures are the most useful for you to take to reduce your environmental impact and lower your carbon footprint (and save money too!)

Browse our information sheets using the menu on the right. These give advice on popular topics, from solar panels to composting toilets. Or take a quick look at our most frequently asked questions.

See our 'what's the problem?' pages for more background on the issues we're trying to address, and to find out what you can do to make a difference.

If you can't find what you need in this section, enter key words into the search box at the bottom left corner of this page to get a list of related pages, publications, courses, and more.

If you still can't find an answer, then fill out an online query form and send it to us. Please also use the form to send us feedback on these pages, so that we can continue to improve them.

In order to keep this service free at the point of use, and to help with CAT's other charitable work, please make a donation if you are able to.
