| Zusammenfassung |
| We developed a new emission inventory for Asia (Regional Emission inventory
in ASia (REAS) Version 1.1) for the period 1980–2020. REAS is the first
inventory to integrate historical, present, and future emissions in Asia on
the basis of a consistent methodology. We present here emissions in 2000,
historical emissions for 1980–2003, and projected emissions for 2010 and
2020 of SO2, NOx, CO, NMVOC, black carbon (BC), and organic carbon (OC)
from fuel combustion and industrial sources. Total energy consumption in
Asia more than doubled between 1980 and 2003, causing a rapid growth in
Asian emissions, by 28% for BC, 30% for OC, 64% for CO, 108% for
NMVOC, 119% for SO2, and 176% for NOx. In particular, Chinese NOx
emissions showed a marked increase of 280% over 1980 levels, and growth
in emissions since 2000 has been extremely high. These increases in China
were mainly caused by increases in coal combustion in the power plants and
industrial sectors. NMVOC emissions also rapidly increased because of growth
in the use of automobiles, solvents, and paints. By contrast, BC, OC, and CO
emissions in China showed decreasing trends from 1996 to 2000 because of a
reduction in the use of biofuels and coal in the domestic and industry
sectors. However, since 2000, Chinese emissions of these species have begun
to increase. Thus, the emissions of air pollutants in Asian countries
(especially China) showed large temporal variations from 1980–2003. Future
emissions in 2010 and 2020 in Asian countries were projected by emission
scenarios and from emissions in 2000. For China, we developed three emission
scenarios: PSC (policy success case), REF (reference case), and PFC (policy
failure case). In the 2020 REF scenario, Asian total emissions of SO2,
NOx, and NMVOC were projected to increase substantially by 22%, 44%,
and 99%, respectively, over 2000 levels. The 2020 REF scenario showed a
modest increase in CO (12%), a lesser increase in BC (1%), and a
slight decrease in OC (−5%) compared with 2000 levels. However, it
should be noted that Asian total emissions are strongly influenced by the
emission scenarios for China. |
