Abstract
With the further aggravation of global warming and the increasingly serious problems of ecological environment, the construction of low-carbon cities has become an inevitable choice for the global response to climate change and the sustainable development of economy and society. In order to understand the basic situation of China’s low-carbon cities more specifically, this paper selects countries with different urbanization rates to carry out benchmarking analysis with China, hoping to draw on the experience of other countries from the national level through multi-dimensional comparison, and guide the direction of China’s future urban development. Firstly, this paper selects the basic indicators such as the total amount of carbon dioxide emissions, per capita carbon emissions and carbon emissions per unit GDP of each country; Secondly, it compares the proportion of coal in energy and other indicators, and analyzes the energy structure of each country in depth; Thirdly, it compares the trend of carbon emissions in each country among 1990-2017. Finally, in order to reflect the carbon emission in the development of urbanization, this paper uses the “urbanization carbon emission index”, which is the ratio of per capita carbon emission and urbanization rate, to show the relationship between the degree of urbanization and carbon emission. Through benchmarking analysis, we can more clearly understand the overall trend of low-carbon city construction in different countries, recognize the gap between China and other countries, and better guide the development of low-carbon cities in China in the future.

In the 21st century, the severe situation of global climate change and energy depletion has seriously threatened human survival
In order to compare the construction level of Chinese and foreign low-carbon cities and understand the development of Chinese low-carbon cities more comprehensively, this paper selects countries with different urbanization rates to carry out benchmarking analysis with China
The UK's policy progress is mainly reflected in released by the Ministry of Environment, Food and Rural Affairs in July 2018.Aiming at the priority areas of climate change in the UK, the plan determines the actions that the UK government and other departments need to take in the five years to meet the challenges of adaptation to climate change [4]
Summary
In the 21st century, the severe situation of global climate change and energy depletion has seriously threatened human survival. In order to achieve the temperature control target of 1.5 °C, it is necessary for countries all over the world to carry out far-reaching and forwardlooking transformation in energy, land, urban and industrial systems. Facing the threat of climate change, low-carbon cities are obviously the inevitable choice for China to achieve sustainable development. In order to compare the construction level of Chinese and foreign low-carbon cities and understand the development of Chinese low-carbon cities more comprehensively, this paper selects countries with different urbanization rates to carry out benchmarking analysis with China. By comparing the main low-carbon construction indicators, we can more intuitively find out the differences between China and other countries in lowcarbon city construction, recognize the shortcomings of its own development, and learn from the experience of other countries at the national level
