Guide to cookies and how they are used on the Carbon Trust website.
A cookie is usually a small piece of data sent from a website and stored in your web browser while you are browsing a website. When you browse the same website in the future, the data stored in the cookie can be retrieved to notify the website of your previous activity.
Cookies are used on more than 90 per cent of sites and serve many functions. For example, they can help us to remember your username and preferences, analyse how well our website is performing, or even allow us to recommend content we believe will be most relevant to you.
Certain cookies contain personal information. For example, if you click on 'remember me' when logging in, a cookie will store your username. Most cookies won't collect information that identifies you, but will instead collect more general information, such as how users arrive at and use our websites or a user's general location.
