A former head of the taxation office has been appointed to the regulator overseeing Labor's carbon price regime.


Michael D'Ascenzo will join the Clean Energy Regulator from April, after ending a six-year stint at the helm of the Australian Taxation Office (ATO) in late 2012.


Climate Change Minister Greg Combet said Mr D'Ascenzo brings a wealth of public sector experience to the role.


The regulator is the government body responsible for administering the carbon pricing mechanism, but also runs the carbon farming initiative and monitors greenhouse gas emissions from corporations.
