基于天津市社会经济发展现状，运用相关计量模型，定量测算了天津市碳排放总量及三大关键领域碳排放量。测算结果表明：2000—2009年，天津市碳排放总量持续增加；2008年，天津市人均碳排放量远高于同期全国人均碳排放水平；2008年天津市工业生产碳排放量为8986．67万t，交通碳排放量为2171．85万t，全生命周期建筑碳排放量为3663．02万t，三者累计达14821．54万t，占碳排放总量的98．54％。因此，未来天津市碳减排的重点应致力于生产、交通及建筑三大领域。%Based on the status of socio-economic development in Tianjin, uses related measurement model to esti-mate quantitatively the total carbon emissions and three critical carbon emissions in Tianjin. The calculated result shows： Tianjin total carbon emissions increase continuously from 2000 to 2009, per capita emissions of 2008 is far higher than the national average, and in 2008 Tianjin industrial carbon emissions is 89.866 7 million tons, the traffic carbon emissions is 21.718 5 million tons, building life cycle carbon emissions is 36.630 2 million tons, which totals 148.215 4 million tons and accounts for 98.54% of total carbon emissions. Therefore, the future carbon emission reduction of Tianjin should mainly focus on three areas, i.e. production, transportation and building.
