Abstract

A six-step methodology for estimating use (Steps 1–5) and emissions (Step 6) of fluorocarbons not regulated under the Montreal Protocol and SF6 has been described, to improve insight into emissions in the Netherlands. The last step is largely in line with methods applied in the annual AFEAS reports and under discussion within the IPCC, and estimates HFCs, PFCs, FICs and SF6 released as the sum of (1) emission from compounds used as substitutes for ozone-depleting compounds (2) emissions due to SF6' historical market and (3) emissions from other industrial processes. Emissions in the Netherlands were estimated for scenarios assuming that the Montreal protocol will be implemented. Without additional measures (reference scenario emissions of HFCs, PFCs, FICs and SF6 increase from 878 (metric) tons in 1990 to 6983 tons in 2020. In 2020 emissions are estimated to be about 21 Mt CO2 equivalents, or 13% of the CO2 target for that year (i.e. stabilization at the 2000 level). Assuming maximum emission control through good housekeeping, recycling and waste destruction, emissions are 40–50% lower than in the no-control scenarios. The closed applications only scenario assumes use of these compounds to be restricted to stationary cooling and closed-foam blowing. In this scenario, emissions are 15–25% (no-control case) and 50–60% (maximum emission control case) lower than in the reference scenario. Reductions up to 90% are found in the low-GWP scenario, assuming an average Global Warming Potential of the mix of compounds used of 250 or less.
