| Zusammenfassung |
| HFC-134a is the most important substitute of CFC-12 used in the mobile air-conditioner in
China since 1995. The bottom-up method was used to estimate HFC-134a emissions in
China, from 1995 to 2030, basing on updated automobile industry data and latest emission
characters. From 1995, total HFC-134a emission has kept a high growth rate of nearly 60%
per year, and reached 16,414.3 Mg (11,959.4–20,834.5 Mg) in 2010, which was equivalent to
23.5 Mt CO2-eq emissions. Furthermore, the emissions in China accounted for nearly half of
total emissions of Non-Annex_I countries in 2008. As for provincial emissions in 2010,
provinces with emission greater than 1,000 Mg are Guangdong, Shandong, Jiangsu and
Beijing. Quantitative relationship between provincial HFC-134a emissions and GRP of the
Tertiary Industry was used to estimate HFC-134a emissions at county level, and Hangzhou
municipal district held the maximum emission intensity (4,605 Mg/10,000 km2). For
HFC-134a, emissions calculated from the observations within 46 cities through Euler box
model are in good agreement with the corresponding emissions estimated from the
bottom-up method, verifying that the emission inventory at county level adequately
describes the emission spatial pattern. For the future emissions of HFC-134a, projected
emissions will reach 89,370.4 Mg (65,959.7- 114,068.2 Mg) in 2030 under the
Business-as-usual (BAU) Scenario, but under the Alternative Scenario, a emission
reduction potential of 88.6% of the projected BAU emissions would be obtained. |
