Dear Colleague,

The China Energy Group of Lawrence Berkeley National Laboratory (Berkeley Lab) is  pleased  to  announce  the release of a new software tool and user guide to support city-level action on climate changeBenchmarking and Energy Saving Tool for Low-Carbon Cities (BEST Cities).

The  BEST Cities  tool was co-developed by the China Energy Group of Berkeley Lab and the Energy Research Institute of China's National Development and Reform  Commission,  and was beta-tested by the Shandong Academy of Sciences.

The  BEST Cities  tool has three main modules: 
(1) Inventory and Benchmarking
(2) Sector Prioritization
(3) Policy Analysis

BEST Cities supports and assists Chinese cities in the development of low-carbon action plans to achieve their energy and climate targets, and also provides benchmarking against other Chinese and international cities. BEST Cities provides a policy database as well as a prioritization mechanism to tailor a plan to each individual city using the tool.  

Highlights include:

Analysis of energy and emissions (COand CH4) in 9 city sectors Industry, Public & Commercial Buildings, Residential Buildings, Transportation, Power & Heat, Public Lighting, Solid Waste, Water & Wastewater, and Urban Green Space.


Benchmarking 35 key performance indicators (KPIs) across 9 sectors and city-wide-including energy intensity and CO2 per capita-utilizing a database of nearly 400 Chinese and international cities.


Characterization of 72 energy and CO2 emissions reduction policies in terms of their carbon savings potential, first cost to government, and speed of implementation.


Prioritization sectors and policies for your city based on sector carbon emissions and improvement potential, city authority, and city capabilities (finances, human resources, and enforcement).

Nan Zhou, above, staff scientist and deputy group leader of Berkeley Lab's China Energy Group, gives a presentation in Beijing on the GREAT and BEST Cities tools.

Berkeley Lab has trained more than 400 researchers, city mayors, policymakers and practitioners to use BEST Cities and other low-carbon tools ( GREAT ELITE Cities , and  Urban RAM ) over the past six years in more than 20 cities in China. Participating cities include Beijing, Guangzhou, Jinan, Kunming, Nanchang, Shenzhen, Shanghai, Wuhan, and others. The BEST Cities tool and user guide are available in English and Chinese. 

Feedback on using BEST Cities:

"The BEST Cities tool helped Jinan City to identify a 62% carbon reduction potential, with 26 million tCO2e of potential savings in the industrial sector, and 2.6 MtCO2e, 1.3 MtCO2e, 8.5 MtCO2e, 1.5 MtCO2e, in Public and Commercial Buildings, Transportation, Power and Heat, and Residential Buildings sectors, respectively."  - Dr. Zhou Yong,Vice Director of the Institute for Development Strategy of Shandong Academy of Sciences

"LBNL's tools are very valuable and customized to Chinese conditions that can be used for low-carbon city pilots, and should be disseminated more widely to more cities through trainings and university educational programs." -  Jiang Zhaoli, Deputy Director General of China's National Development and Reform Commission

"With the support of LBNL... and collaboration and use of green-tech tools, e.g. BEST Cities... Shenzhen won the prize of Annual Outstanding Eco-City Case of China in 2014 and the 2014 Prize for Cities of the Future Award by the China Center for International Economic Exchanges (CCIEE) and the Paulson Institute." -  Li Angang, Deputy Director of Shenzhen International Low-Carbon City Planning and Development Office

David Vance Wagner, China Counsellor, Office of the Special Envoy for Climate Change, U.S. Department of State, gives opening remarks at a recent city tools training workshop in Beijing.

Low-Carbon City Policy Databook

In addition to the BEST Cities tool and user guide, the China Energy Group is releasing an extensive  Low-Carbon City Policy Databook  from the policy database developed for the BEST Cities tool. For each of the 72 policies, this report provides a two-to-four page explanation and characterization, which includes: a Policy Description, Implementation Strategies and Challenges, Monitoring Metrics, Case Studies, Policy Attributes (Carbon Savings Potential, First Cost to Government, Speed of Implementation), as well as Tools and Guidance, and References.

Please feel free to forward this information to others interested in low-carbon cities in China.

Please  direct questions about BEST Cities to Sammi Leung (510-486-7698, ) at Lawrence Berkeley National Laboratory.

The BEST Cities tool and the Low-Carbon City Policy Databook were developed with the generous support of the Energy Foundation China through the Department of Energy under contract No.DE-AC02-05CH11231. We would like to thank Steve Hammer of the Urban Development and Resilience Unit of the World Bank, Ivan Jacques and Pedzi Makumbe of the World Bank's Energy Sector Management Assistance Program (ESMAP), and programmers Ben Ede and Mike Spears, for their helpful assistance in the development of the BEST Cities tool.

BEST Cities is partly based on a model known as TRACE, the Tool for the Rapid Assessment of City Energy, originally developed by the World Bank's Energy Sector Management Assistance Program (ESMAP) 

We are grateful to China's Energy Research Institute for policy review and translation. We also thank Dr. Zhou Yong of the Shandong Academy of Sciences and Stephane de la Rue du Can of LBNL for additional review of the policies.

BEST Cities 工具由劳伦斯伯克利国家实验室中国能源组和国家发改委能源研究所共同开发,并由山东省科学院进行测试。 

BEST Cities 工具有三个主要模块: 

BEST Cities工具帮助中国城市开发低碳行动方案帮助其实现能源和气候目标,并与中国其他城市和国际城市进行基准化比较。BEST Cities提供政策数据库以及优选机制帮助各城市制定相关计划。  

BEST Cities工具有几大亮点:
  • 在九大行业分析能耗和碳排放(二氧化碳和甲烷):  工业、公共建筑、居住建筑、交通、热力和电力、公共照明、水和废水、固体废弃物和城市绿地
  • 覆盖9大行业的基准化35项关键绩效指标 (KPIs) ,包括能源强度和人均二氧化碳排放,数据包括400多个中国和国际城市 
  • 72项节能减排政策详细分析, 包括碳减排潜力,政府初始成本,以及实施速度
  • 针对城市优选部门和政策, 根据行业节能减排潜力、城市政府权限和城市能力(财力状况、人力状况和执行力)

劳伦斯伯克利国家实验室科学家、中国能源组副主任周南博士在北京介绍 GREAT和BEST Cities 工具

劳伦斯伯克利国家实验室在过去6年中已经在中国二十多个城市培训了四百多名研究者、市长、决策者和从业者,包括BEST Cities工具和其他低碳工具 ( GREATELITE Cities, 和 Urban RAM) 。参与城市包括北京、广州、济南、昆明、南昌、深圳、上海、武汉等。BEST Cities工具和使用指南都是中英双语。 

截止到目前,我们已经收到关于 BEST Cities工具的很多积极反馈:
山东省科学院发展战略研究所副所长周勇说: "The BEST Cities工具帮助济南市确认了 62%的减排潜力,其中工业部门减排潜力达 2600万吨 CO2e ,公共和商业建筑部门、交通部门、电力和热力部门以及居住建筑部门减排潜力分别达 260万吨 CO2e, 130万吨 CO2e, 850万吨 CO2e150万吨 CO2e"

国家发改委气候司副司长蒋兆理说: "劳伦斯伯克利国家实验室的工具是适合中国国情的,可以在低碳试点城市中应用,非常有价值。应该通过培训和高校教育推广到更多的城市。 "

深圳国际低碳城规划建设领导小组办公室副主任李安刚说: "通过劳伦斯伯克利国家实验室的支持与合作,以及绿色技术工具的使用,例如 BEST Cities工具,深圳赢得了 2014年中国杰出生态城市奖和 2014年中国国际经济交流中心和保尔森基金会未来城市奖。 "



除了BEST Cities工具和使用指南,中国能源组在此发布 低碳城市政策库。本报告由 BEST Cities工具的政策数据库开发而来,对 72项政策进行了详细阐述,每条政策有 2-4页的阐述 ,包括政策说明、实施策略与挑战、检测指标、案例研究、政策特征(减排潜力、政府初始成本、实施速度)、以及工具和指南和参考文献。
