Celebrating the Paris Agreement’s fifth anniversary, the United Nations and other parties hosted the Climate Ambition Summit on December 12, 2020. The summit heard announcements from 75 leaders, including 45 relating to new and enhanced NDCs, 24 net-zero emissions commitments, and 20 new adaptation and resilience plans. Pledging climate ambitions for a low carbon economy and carbon neutrality do not guarantee their achievement. More challenges and hurdles are ahead considering those challenges require all stakeholders involved within and across countries, not a matter of developed or developing countries. What we need is action rather than words to induce more investment and innovation for climate neutrality.
