Warning! As of 20 September 2021, the EU lobby register has changed format. Temporarily, the register is no longer providing daily data updates of all lobby data which means that the figures on LobbyFacts cannot currently be kept up-to-date. If, for example, you see a company, trade association, or lobby consultancy with "no figure available" for EU lobby costs, open the data card, and click the link to the EU lobby register where you will find the updated registration including EU lobby costs declaration. Regretably, under the lobby register format, NGOs and think tanks are no longer required to provide a figure for EU lobby costs. We will update LobbyFacts with the new data as soon as possible.
