Maintaining political momentum on an issue like climate change can be hard, public interest often glazing over at the frequent debate on emission targets and empty rhetoric.
But a young Auckland doctor and other activists are gaining real attention - and causing a few politicians to look over their shoulders - by focusing on specifics and possible solutions.
Dr Sudhvir Singh, 26, is the Auckland director for Generation Zero, a group of mostly young professionals promoting solutions to climate change through transport, energy and liveable cities.
Many Aucklanders will have seen the London Underground-style posters outlining the group's transport vision, with rail, bus, light-rail and ferry routes stretching out through the Super City by 2030.
