Significant climate anomalies 2008/2009. Source: Climate Change Compendium. A UN review of some 400 major scientific contributions to Earth systems and climate science released through peer-reviewed literature or from research institutions over the last three years, has found that the pace and scale of climate change may now be outstripping even the worst case predictions of the last report of the Intergovernmental Panel of Climate Change (IPCC).

Compared to the 2010 “Business as Usual” scenario—which includes all adopted emission control measures for the South Coast—NO x levels must be reduced by 65% and by 75% to meet the 2023 and 2032 ozone standards, respectively.

Criteria that account for the effects of land-use change, or that restrict the types of biofuel feedstocks, could have greater utility. A few studies also include other relevant impact indicators as acidification potential, eutrophication potential, ozone depletion potential and various toxicity potentials. More specifically, only one third of the studies define an alternative land use reference system and calculate the carbon stock.
