城市are starting to get serious about curbing climate change. In the past two years,more than 500 cities全世界都加入了市长的契约,这是一个致力于雄心勃勃的气候行动的联盟。必威官网是真的吗今年,市长与市长盟约合并以形成新的Global Covenant of Mayors,有6,000多个城市和市政当局。这个全球团体加入了许多致力于城市气候行动的地区和国家倡议,例如中国必威官网是真的吗先锋峰城市联盟(APPC)是一组20多个中国城市,他们致力于在2030年全国目标年之前达到其温室气体(GHG)排放。

But with all these great commitments comes the next logical question: How to put them into action?

Chengdu, China, Puts Evidence-based Low-carbon Planning into Practice

除了承诺外,城市还需要系统的计划才能达到其气候目标。必威官网是真的吗根据市长的契约,该计划应包括四个关键步骤:

  1. 开发温室气库存;
  2. 设定减总目标;
  3. 制定行动计划;和
  4. track performance on a regular basis.

实用的指南和工具,例如社区规模的温室气体排放库存(GPC),可以帮助城市实施这些步骤。超过500个城市,总人口总数为4.4亿吨,每年的温室气体排放量达到近30亿吨),他们致力于使用GPC衡量其排放量,以制定行动计划,以减少排放并公开报告其进度。

中国成都以这四个步骤进行低碳规划。成都拥有超过1400万的人口,是中国最大的城市之一,快速工业化和城市化导致了数十年来的温室气排放量增加。当成都与WRI的可持续和宜居城市倡议合作时,这种情况开始发生变化。

成都发展与改革委员会开发了第一个温室气库存in 2015 (based on 2010 data). This inventory revealed valuable insights about the sources of the city’s emissions. For example, it was found that Chengdu’s electricity is quite low-carbon because more than 70 percent of it is hydroelectric. So shifting industries toward electrification could be a way to further reduce Chengdu’s carbon emissions.

Using the inventory results, Chengdu then created a detailed analysis to forecast its potential future emissions trajectories under different economic, energy and mitigation scenarios. It found that controlling emissions from construction materials manufacturing and chemical industries are among the key measures needed to peak the city’s emissions. In terms of energy mix, limiting oil consumption and increasing electrification will lower the emissions peaking level. Based on the analysis, Chengdu committed to an ambitioustarget到2025年,其排放量达到顶峰announcedat the China-U.S. Climate-Smart / Low Carbon Cities Summit in June. Then, Chengdu developed a detailed roadmap and行动计划为了实现包括设置能量帽,建立智能电网,建立低碳运输和建造绿色建筑物的措施的目标。今年,成都将使用2015年数据更新其温室气体清单,并制度化跟踪性能的机制

National Policies: The Other Piece of the Puzzle

为了帮助应对气候变化,越来越多必威官网是真的吗的城市需要像成都一样采取行动。诸如市长的紧凑型和新的全球市长盟约之类的国际平台可以提供帮助,但国家政府也发挥了作用。

国家政府需要将城市的行动与国家政策联系起来,以从各级政府的政治利益相关者那里获得买入。这将有助于城市利用国内政策和融资机制。将城市行动与国家政策联系起来也可以加快变革。例如,中国将低碳城市作为其国家气候议程的重中之重。必威官网是真的吗在2011年和2012年,国家发展与改革委员会选择了42个城市和省份加入国家飞行员低碳城市计划。该计划的成功促使委员会今年增加了大约50个新城市。所有这些城市和省份将在2030年国家目标之前设定排放峰值目标,以表明国家政府如何帮助实现大规模取得成果。

Curbing climate change is a herculean feat. While countries have reached consensus on the Paris Agreement, tackling global warming will ultimately require on-the-ground action in countries and cities. More cities should join Global Covenant of Mayors and APPC cities to ratchet up their actions in line with the Paris Agreement.
