Development of low-carbon economy has become the new mode of economic growth. In order to study whether a countrys economy is able to achieve rapid economic growth under the constraints of carbon emission reduction, The impact of carbon emission reduction constraints on economic growth is discussed in this article under the endogenous growth theory framework. This article limit on the total level of carbon emissions rather than carbon emissions intensity. Simplicity we assumed that energy use is the sole source of carbon emissions and the only way for the economy to achieve carbon reduction goals is the reduction of fossil energy use. Technological improvement will promote the growth of output and non-fossil energy use. At the same time, we introduced people’s concerns of atmospheric carbon stock to the utility function, the increase in the stock of carbon in the atmosphere will reduce the peoples immediate utility. We analyzed the impact of carbon emission intensity and the speed of carbon emission reduction on economic growth, and the conditions that must be met to achieve positive economic growth rate through the model. The study found that under certain constraints, there is a feasible and optimal sustainable growth path which can achieve the dual goals of economic growth and carbon emission reduction. The improving of energy structure and technological progress is the essential condition for economic growth. The impact of production function as well as peoples degree of risk aversion, the concept of sustainable development on economic growth cannot be ignored. To achieve a low-carbon economy should be step by step. Lower emission reduction targets should be
