Nanomaterials describe, in principle, materials of which a single unit is sized (in at least one dimension) between 1 to 1000 nanometres (10−9 meter) but usually is 1 to 100 nm (the usual definition of nanoscale).
Different regions and economic sectors are dealing with the impact of climate change in different ways. A framework to optimise these responses under different scenarios has been developed under the auspices of an EU-funded initiative.
