气候变暖背景下的低碳可持续发展及碳足迹计算

发达国家自工业革命后的100余年中释放了大量温室气体使地球气候变暖,造成海平面上升,极端天气频现,危害人类生命安全.联合国为此多次召开气候大会,其中具有里程碑意义的有2次:(1)1997年气候会议签署《京都议定书》,确定6种温室气体,开启低碳可持续发展道路并建立碳足迹制度;(2)2015年气候会议中大部分国家签署《巴黎...

Low carbon sustainable development and carbon footprint calculation under the background of climate warming

Developed countries have released a large number of greenhouse gases in more than 100 years since the industrial revolution, warming the earth′s climate, causing the rise of sea level and frequent extreme weather, endangering human life safety. The United Nations had held many climate conferences for this purpose. There were two milestones:(1) the 1997 climate conference signed the Kyoto Protocol, identified six greenhouse gases, opened the path of low-carbon sustainable development and established a carbon footprint system;(2) most countries signed the Paris Agreement in the 2015 climate conference, the climate temperature rise would be limited to within 1.5 ℃ before the middle of the 21 st century, and it was stipulated that before the United Nations Climate Change Conference in Glasgow in November 2021, countries needed to commit to zero carbon emission or carbon neutralization. At the 40 nation leaders′ climate summit on April22~23, 2021, major economies have put forward corresponding goals and stepped up the research and development of renewable energy to achieve the promised goals.
