This catalogue produced by the Italian Ministry of Environment, Land and Sea (MATTM) in response to a request by the Parliament is part of a wider effort on fiscal reform. The catalogue aims to identify intervention areas for a possible reform of general taxation in accordance with the polluter pays principle, measures which can contribute to an environmental fiscal reform and areas for a possible reduction of fiscal expenditures in general.  The Catalogue analyses subsidies by sector: agriculture, energy, transport, VAT and other subsidies, considering both fiscal expenditures and direct subsidies. This is the first version of the catalogue which will be updated annually and the scope expanded to include other types of subsidies. The catalogue is available on the website of the Ministry (in Italian with English translations of the Introduction and Summary).
