In response to attribution of recent climate change, the City of Melbourne, in 2002, set a target to reduce carbon emissions to net zero by 2020 and Moreland City Council established the Zero Moreland program, however not all metropolitan municipalities have followed, with the City of Glen Eira notably deciding in 2009 not to become carbon neutral. Melbourne has one of the largest urban footprints in the world due to its low density housing, resulting in a vast suburban sprawl, with a high level of car dependence and minimal public transport outside of inner areas. Much of the vegetation within the city are non-native species, most of European origin, and in many cases plays host to invasive species and noxious weeds. Significant introduced urban pests include the common myna, feral pigeon, brown rat, European wasp, common starling and red fox. Many outlying suburbs, particularly towards the Yarra Valley and the hills to the north-east and east, have gone for extended periods without regenerative fires leading to a lack of saplings and undergrowth in urbanised native bushland. The Department of Sustainability and Environment partially addresses this problem by regularly burning off. Several national parks have been designated around the urban area of Melbourne, including the Mornington Peninsula National Park, Port Phillip Heads Marine National Park and Point Nepean National Park in the south east, Organ Pipes National Park to the north and Dandenong Ranges National Park to the east. There are also a number of significant state parks just outside Melbourne. Responsibility for regulating pollution falls under the jurisdiction of the EPA Victoria and several local councils. Air pollution, by world standards, is classified as being good. Summer and autumn are the worst times of year for atmospheric haze in the urban area.

Who is responsible for regulating pollution in Melbourne?
Answer:
EPA Victoria and several local councils
