The frightening part of climate change is the speed with which we need to act to bring about any meaningful reduction in greenhouse gasses.
Governments are notoriously slow to act, and measures introduced take a long time to bite. To complicate matters even more, technological developments are coming faster and faster.
Governments must therefore design policy around outcomes, not particular technologies.
For example, lighting technology has already outpaced climate change policy. As my latest business briefing paper Energy efficient LED lighting ready for the big time explains, well-intentioned schemes like the NSW Greenhouse Gas Reduction Scheme encourage use of dangerous, second-rate fluorescent lighting when much better alternatives now exist.
