2011 saw several conversions of production plants to hydrocarbons in developing countries, as well as new hydrocarbon products and investments in serial production. Meanwhile, end-users continued the deployment of natural refrigerants in line with their sustainability commitments, while major policy developments such as the opening of the US market to hydrocarbons, the HFC tax in Australia, or the prospect of a strengthened policy on f-gases in the EU prepare the ground for an even better year for hydrocarbons in 2012.
