In China, the market for extruded polystyrene (XPS) foam used in building insulation increased the last years at double digit growth rates due to the fast rise of the economy and the associated construction boom. This growth in the market for insulation is brought about by new regulations on building insulation as part of the Chinese energy efficiency programme. Currently, Chinese XPS-producing companies are using fluorinated blowing agents such as the ozone-depleting HCFCs or their HFC-alternatives which are both significantly contributing to climate change due to their high global warming potential (GWP).
