The White Paper was released on 15 December 2008. The White Paper included the Rudd Labor government's targets for Greenhouse gas emission reductions, 5% below 2000 by 2020 on a unilateral basis or up to 15% below 2000 by 2020 if also agreed by the other major emitters. This compares to the 25 to 40% cut compared to 1990 emissions recommended by the IPCC as needing to be made by developed countries to keep CO2 below 450 ppm and to have a reasonable chance of keeping global warming at less than a 2-degree Celsius increase above pre-industrial times.
