On November 7, the second day of the 23rd United Nations Climate Change Conference of Parties (COP23) held in Bonn, Germany, China Green Carbon Foundation (CGCF) and the Natural Resources Defense Council (NRDC) co-organized a side event titled, “Belt and Road: NDCs and Green Development.” The first in a series of side events sponsored by the Belt and Road Green Development Partnership at COP23, the event was moderated by Yang Fuqiang, a steering committee expert of the Partnership, and Senior Advisor at NRDC. Dr. Yang noted that the Belt and Road Initiative (BRI) involves many developing countries that are ecologically vulnerable and face multiple challenges of poverty alleviation, environmental protection, and climate change response. Investment and cooperation under BRI is therefore critical toward the sustainable economic and social development, and NDC implementation of BRI countries. China has actively responded to climate change by taking effective measures to uphold green development as a key principle of BRI cooperation. Project-level cooperation must pay close attention to environmental and climate impacts, as well as the sustainability of development, in order to help BRI countries realize their intended goals under the Paris Climate Agreement.
