This is the reason that emissions projections are made for the chemical industries as a whole. The consumption of HFCs in Bulgaria depends on domestic production and manufacturing for domestic consumption - the filling of newly manufactured products and refilling of equipment - or on precharged equipment. The emissions in 2011 had decreased by 67 per cent compared with 1988. In 2011, GHG emissions from industrial processes were 3,977.93 Gg CO2 equivalent, compared with 11,959.94 Gg CO2 equivalent in 1988.
