Urban carbon emissions trends and the effect of mitigation measures

This paper, taking Beijing, Tianjin, Shanghai of China for example, discussed the method of urban carbon emissions prediction. Using Yongbin Zhu and Zheng Wang's optimal growth model to study the energy carbon emissions of cities under steady economic growth, and getting forest carbon sinks of cities with CO2FIX model, then we could result in net carbon emissions of cities. The results showed that in Beijing, Tianjin and Shanghai, net carbon emissions presented inverted U-curve of growth, but were not very different from the situation when we didn't consider forest carbon sinks. Scenarios showed that speeding up technological progress in Beijing and Shanghai to reduce energy carbon emissions had no significant effect, but in Tianjin it had an obvious effect.
