In 5 Degrees of Change some of the most influential voices on Energy and Environment will propose 3 big policy changes based on their area of expertise, and also outline two small personal changes they have made to contribute to a greener environment. In episode one, host Daniel Murray is joined by economist John FitzGerald. John has been an influential voice in Irish public life over a long and storied career that includes three decades spent with the Economic and Social Research Institute as well as a stint in the Department of Finance. John now chairs the Climate Change Advisory Council which directly advises the government on climate issues. He has always been seen as an exceptional communicator, being independently minded and of a creative persuasion, all attributes which are on clear display as he shares his five degrees of change.
