Is this only about big business lobbying? What about NGOs and trade unions?

Of course NGOs and trade unions carry out lobbying activities, although in truth their numbers are far smaller than the number of industry lobbyists in Brussels. A particular concern for ALTER-EU is the direct revolving door between the EU institutions and the lobby consultancy industry in Brussels. Nonetheless, the revolving door rules which ALTER-EU proposes would cover lobbying carried out by all types of organisations, including NGOs and trade unions.
