Aluminium industry sucked into global warming debate

The scientific community has overlooked two of the most potent greenhouse gases in its assessments of the pollutants contributing to global warming, according to a US scientist.1 Both are emitted from primary aluminium smelters, and their involvement in global warming will now need to be taken into account in life-cycle analyses of the environmental effects of aluminium products.

Scientists' attempts to identify the main sources of greenhouse gases continue to throw up surprises. Only last year, nylon production was pinpointed as a major emitter of nitrous oxide. The global warming effect of this source in the UK is equivalent to 4% of that from its carbon dioxide emissions (ENDS Report 206, pp 26-7
