The rise of COVID-19 and extreme weather risks in recent years has brought unprecedented policy attention to addressing climate change and sustainable development in both developed and developing economies. Many countries have already made commitments for carbon neutrality by mid-century，as required by the Paris Agreement，and have put in place a range of policies and tools to support carbon peak and carbon neutrality. According to the Nationally Determined Contributions（NDCs）submitted to the UNFCCC，most countries have taken emission reduction in key sectors such as energy，power，industry，transport and construction，carbon sinks，innovation and investment as strategic priorities in moving towards carbon neutrality. As more and more countries and enterprises speeding up the decarburization process，the prospect of a “carbon neutral” world is promising. But for developing countries，the challenge of carbon neutrality cannot be ignored，for example，how to realize the significant transformation of the energy structure，how to alleviate the pressure of the industrialization and urbanization brings on emission reduction，how to crack technical and financial problem，how to enhance the resilience of the economy. Governments therefore play an important leading role in this process，and need to integrate more green factors into economic stimulus packages and long-term development strategies at the domestic level，stimulate the emission reduction potential of local government and non-governmental actors，and meantime strengthen international dialogue and cooperation on green and low-carbon products and technologies.
