This website uses the 'strict' implementation of XHTML and should therefore display correctly with all modern web browsers which interpret the standard correctly. It has been tested using Internet Explorer 8, Firefox 2.0.0.6. and 3.0.1 and Google Chrome, all running under Windows XP SP3. It has not been tested on any Apple operating system or on any implementation of Linux, nor on any browser not listed above and no liability is accepted for shortcomings which may be evident using other browsers or operating systems. You may notice differences in appearance between different browsers; this is generally the result of differences between the browsers themselves, but if these make the site unusable in any browser please let us know.
This site does not use Cookies and does not collect any information about visitors. However the external websites powering the Carbon Calculator, and the Carbon Emissions display (both on the Climate Change page) may use Cookies.
The site will generally display correctly if you have turned 'show pictures' off in Internet Options to reduce download times; menus do not use graphic images and therefore remain usable even when 'show pictures' is off.
However it is not practicable to test all the possible combinations of Internet Options.
