As in previous assessment reports, the HTOC is providing the most current estimates of inventories for halon 1211 and halon 1301 based on modelling of known production and estimated emissions. Very little has changed with halons 1211 and 1301 on the global level since the 2006 Assessment. Therefore, the global estimate of inventories and emissions for halons 1211 and 1301 provided in this report is the same as provided in the 2006 Assessment. Some additional information on regional estimates of emissions for halons 1211 and 1301 has become available and is provided in a separate section within this chapter. For halon 2402, there remains little open literature information available on inventories and emissions. The HTOC has provided updated information and created a rough global estimate of banks and emissions.
8.1Emissions and Inventories of Halon 1301
Table 8-1 provides the HTOC 2006 Assessment of current estimates of inventories for halon 1301. Figure 8-1 provides the regional distribution of the global inventory of halon 1301. According to the HTOC Model for halon 1301, as shown in Table 8-1 and Figure 8-1, over 35% of the current inventory of halon 1301 is projected to be in Japan. Although the regional disparity in the distribution of halon itself does not constitute necessarily a regional imbalance, it is anticipated that regional imbalances may result in shortage in one country or region with excesses in other countries and regions.
