岘港市近年来已成为越南增长最快的城市，预计城市面积和人口将随着经济的快速增长而增加。面对气候变化这一人类有史以来面临的最大挑战之一，越南政府在COP26上宣布了到2050年实现净零排放的承诺，以实现2015年《巴黎协定》设定的目标。根据这一国家愿景和最近批准的岘港市十年环境规划，制定地方气候变化行动计划（LCCAP）以及岘港主要部门的具体减排目标变得越来越重要；城市 ；本出版物是岘港市气候行动计划概念框架的第二版，其中包括废物管理和综合城市规划部分的新发展。通过地方利益相关者会议和国际专家合作，还修订了水系统和当前风险章节以及其他四个关键章节 ；这项气候行动计划希望能够鼓励所有公民了解迫切需要什么，以及我们自己今天可以为克服气候危机做些什么
The Intergovernmental Panel on Climate Changes’ (IPCC) Sixth Assessment Report (AR6) has delivered another wakeup call about the need for drastic cuts to greenhouse emissions by 2035 to avoid the most devastating impacts of climate change to human well-being and ecosystems. Carbon dioxide (CO2) may be the most well-known greenhouse gas (GHG), but others, known as non-CO2 or short-lived climate pollutants, also have a critical role to play in keeping the Paris Agreement’s 1.5 degrees C (2.7 degrees F) temperature goal within reach, while also improving air quality and protecting health. , Short-lived climate pollutants — methane, black carbon and hydrofluorocarbons (HFCs), which are also sometimes known as “super pollutants” — remain in the atmosphere for less time than carbon dioxide but have a potent impact on near-term global warming. For example, methane has more than 80 times the warming power of CO2 in its first 20 years in the atmosphere. And about 45% of today's net global warming is driven by methane emissions from human activities. Moreover, methane is also a precursor for another powerful driver of climate change: tropospheric (ground-level) ozone.
根据最近的气候科学研究，将全球变暖限制在1.5摄氏度仍然是可能的。但是为了避免出现严重的气候影响，到2030年，全球温室气体排放量需要减少近一半，并最终实现二氧化碳净零排放。 针对于净零排放，有八个常见问题：1.净零排放意味着什么？2.世界何时需要实现净零排放？3.世界是否有望按时实现净零排放？4.实现净零排放需要做什么？5.有多少国家设定了净零目标？6.《巴黎协定》是否要求各国实现净零排放？7.各国为何以及如何将其近期减排目标与长期净零目标保持一致？8.净零目标是一种“漂绿”形式吗？ 简而言之，这几个问题总结了净零目标的关键点，但是只有各地政府保持净零排放的承诺有力，才能有效推进气候行动。各国如果想要有效应对眼前的挑战，就必须采取具体行动。
The science is clear about how to prevent increasingly dangerous and irreversible climate change impacts: Limit global temperature rise to 1.5 degrees C (2.7 degrees F), which means cutting GHG emissions in half by 2030 and reaching net-zero CO2 emissions by mid-century. , While countries, companies, cities and investors have announced some encouraging commitments to help achieve this global goal, they’re far short of what’s needed. Worse still, new research shows the world’s highest-emitting sectors — power, buildings, industry, transport, forests and land, and food and agriculture — aren’t acting anywhere near fast enough.
