In addition to reorganising data, a clear visual identity for the city of Tallinn was adopted, helping inhabitants, stakeholders and cooperation partners perceive the city’s activities as a whole. Updates to the website make the information concerning topical environmental issues in Tallinn, incl. nature conservation, landscaping, waste and environmental campaigns, easier to find and more current. Prints and information materials compiled and issued by divisions of the Tallinn Environment Department have now been grouped under a separate field. Another important change is that users will now be able to find the contact information of a specialist they need much easier. The website will also contain news of this particular field, topic pages and databases. Actually this website is only in Estonian, but we will do our best to translate also at least a part of this information into English. 4 5 Environmental protection Tallinn Environment Department 2018 1.
