Introduction
Climate change is one of the most significant challenges for sustainable development. It brings uncertainty
and risk for policymakers trying to help shape the future of cities. To avoid the worst effects on quality of
life, biodiversity, and critical infrastructure, ambitious and accelerating action to deal with the issues of
climate change exists – foremost among which is making rapid and significant reductions in greenhouse
gas (GHG) emissions. In this context, the United Nations (UN) and the International Organization for
Standardization (ISO) along with numerous national organizations worldwide, place great importance on
addressing this aspect of climate change. In December 2015, 196 countries and regions globally signed the
Paris Agreement, the first truly global agreement aimed at tackling climate change. The core goal is to limit
the global average temperature increase to below 2 °C above pre-industrial levels and endeavour to limit it
to 1,5 °C. The Intergovernmental Panel on Climate Change (IPCC) report, Climate Change 2021: The Physical
Science Basis, points out that to control global warming, all countries and organizations work together to
implement net zero emissions strategies.
As of October 2024, the number of countries worldwide that have put forward carbon neutrality goals
has increased to 151, covering nearly 92 % of global GDP, 89 % of the global population, and an estimated
88 % of global GHG emissions. The United Nations Sustainable Development Goals (SDGs) emphasize that
cities are key players in net zero. According to statistics from UN-Habitat, cities consume 78 % of the
world's energy, and over 60 % of GHG emissions originate from urban areas. Reports from both the United
Nations Environment Programme (UNEP) and the IPCC highlight the essential role of cities in combating
climate change. Achieving sustainable cities and communities and attaining net zero emissions presents a
formidable challenge. This urgently needs exploring while attaining net zero emissions solutions tailored
to cities and communities, which are essential for meeting the challenges posed by climate change. Many
cities have already taken actions to address their GHG emissions, such as Beijing Future Science City (BFSC),
Marseille and Moscow.
ISO is developing technical standards to support industries or organizations in their climate change
initiatives and to foster coordinated efforts in the global battle against climate change. For example,
IWA 42 and ISO 14068-1 provide tools and guidance for policymakers and organizations to achieve net zero
emissions. IWA 42 establishes a global framework to help regional, city and organizational participants in
coordinating, understanding, and planning programs to achieve net zero emissions. ISO 14068-1 guides
organizations on measuring, reporting and managing their GHG emissions to enhance environmental
performance and combat climate change.
However, cities, which often encompass multiple sectors such as energy generation and consumption,
transportation and industry, still lack International Standards for systematically reducing greenhouse gas
emissions. To tackle this challenge, accurate data collection and analysis, alongside effective management
practices and technological solutions, are essential. While the timing for establishing International
Standards is not yet optimal, compiling best practices from various countries will offer valuable references
and learning opportunities for all.
This document provides use cases that focus on policies, supportive technologies and management methods
for global cities and communities to make progress towards net zero emissions goals (corresponding to IWA
42) and address climate change and global carbon neutrality goals based on consensus (corresponding to
ISO 14068-1). This document takes into account varying climate and environmental conditions as well as the
impact of scale, available resources and economic structures in order to analyse goals, strategies, plans and
effectiveness of implementation, as well as important cross-cutting themes such as low-carbon technologies,
public participation, monitoring and verification.
This document includes cases from three continents and eleven countries, highlighting the shared need
among stakeholders for guidance and comprehensive management approaches. Clause 4 provides a
framework and ten themes that were developed through discussions with stakeholders for collecting cases.
Clause 5 systematically summarizes the carbon neutrality experiences and achievements of cities at various
development stages across different regions, drawing on an analysis of 20 cases derived from two collection
rounds and key findings summarized out of the global open webinars, which collectively cover ten themes:
— governance and regional coordination;
— local actors, partners, participants or citizenship initiatives;
vi
— industry and sustainable production and consumption;
— energy;
— construction;
— transportation;
— agriculture, forestry, and other land uses (AFOLU);
— circularity;
— living and working environment;
— other.
Clause 6 concludes with findings and recommendations to explore innovative future pathways for net
zero carbon cities development. Annex A provides a brief overview of cases from open webinars and
corresponding relationships between cases and ten themes.
Insights from global net zero carbon cities and stakeholder needs identified during open webinars contribute
to the development of this document for net zero carbon cities. This document is intended to expand into
a comprehensive series. This document presents global case studies from various regions and sets a solid
foundation for the following parts of the series. ISO 37115-2 is intended to reference these case studies and
use the ten themes from this document as its core framework to support the development of net zero carbon
cities. Future parts of the ISO 37115 series are intended to provide guidance on urban planning, industrial
zones, carbon assessment, and more, addressing the diverse concerns of stakeholders.

4 Framework for case studies
4.1 General
This clause provides a precise analysis of terminology and definitions of relevant documents from
international organizations and sources of urban greenhouse gas emissions (see 4.2), clearly distinguishing
between terms such as "net zero" and "carbon neutrality" (see 4.3). Additionally, it offers ten themes that
determine the framework of case studies to guide the efforts of urban GHG emission reductions (see 4.4).
4.2 Sectors committed major contributions to urban GHG emission
GHG refers to gaseous components in the atmosphere that can both absorb and re-emit infrared radiation,
including those that are naturally occurring and man-made. The sources of GHG refer to any process or
activity that causes GHG, aerosols, or precursors, to be released into the atmosphere. Sources can be divided
into two major categories: anthropogenic and natural. This document primarily focuses on a detailed
analysis of anthropogenic sources.
Anthropogenic sources of GHG include:
— fossil fuel combustion;
— land-use change and forestry;
— livestock and agricultural practices;
— waste management;
— industrial processes.
The IPCC, in its “Climate Change 2023 Synthesis Report” categorizes GHG sources primarily by sector, for
example, energy, industrial, agriculture, forestry, other land-use sectors, transportation and construction.
International Energy Agency (IEA) publication Net Zero by 2050 demonstrates that achieving net zero
emissions demand rapid, large-scale deployment of all available clean energy technologies, including
renewables, electric vehicles, and energy-efficient building retrofits, by 2030.
The UN Environment Programme’s Emissions Gap Report 2023 highlights that “Energy (generation) is the
dominant source of GHG emissions, currently accounting for 86 % of global CO emissions. The coal, oil and
gas extracted over the lifetime of producing and under-construction mines and fields as of 2018 would emit
more than 3,5 × the carbon budget available to limit warming to 1,5 °C, with a 50 % probability, and almost
the size of the budget available for 2 °C, with a 67 % probability. Global transformation of energy systems is
thus essential, including in low- and middle-income countries, where pressing development objectives were
met alongside a transition away from fossil fuels.”
UNEP Emissions Gap Report 2023 juxtaposes CO emissions from existing fossil fuel infrastructure against
carbon budgets for the Paris Agreement’s 1,5 °C (50 % likelihood) and 2 °C (67 % likelihood) long-term
temperature goals.
Although the GHG emissions information from different countries has unique characteristics, data
from regional organizations such as China’s Ministry of Ecology and Environment (MEE), the European
Environment Agency (EEA), and the U.S. Environmental Protection Agency (EPA) show that energy and
industrial activities are the primary sources of global GHG emissions. In China, GHG emissions mainly stem
from energy and industrial activities. According to the Second Biennial Update Report on Climate Change of
the People’s Republic of China, energy activities are the main source of China’s GHG emissions, accounting
for about 86,8 % of the total CO emissions. The EEA’s European Environment — State and Outlook 2021
categorize GHG emission sources as follows: energy supply, industrial processes, agriculture, waste
management, transportation, and other sectors. The EPA’s Inventory of U.S. GHG Emissions and Sinks 2022
classifies GHG emission sources as follows: energy-related sources, industrial sources, agriculture, land
use change and forestry, waste management, and other sectors. IWA 42 primarily focuses its attention on
the emissions of GHG within the domains of forestry, land use, agriculture, electricity generation, cement
production, steel manufacturing, service buildings and residential structures.
In summary, research reports by international organizations highlight distinct sector characteristics in
global GHG emissions. These emissions are mainly concentrated in the energy, industry, transportation,
construction and waste management sectors.
4.3 Examining “net zero” and “carbon neutrality”
There are some terms in the field of GHG emission reductions, such as "net zero" and “carbon neutrality,” that
can potentially be conflated. IWA 42 provides tools for policymakers and those committed to achieving net
zero emissions for their enterprises, groups or countries, while ISO 14068-1 offers a relatively standardized
pathway to achieving carbon neutrality, guiding organizations, products and services (including events and
buildings) to achieve carbon neutrality through quantifying, reducing and offsetting GHG emissions.
IWA 42 defines "net zero" as a condition in which human-caused residual GHG emissions are balanced by
human-led removals over a specified period and within specified boundaries. Human-led removals include
ecosystem restoration, direct air carbon capture and storage, reforestation and afforestation, enhanced
weathering, biochar and other effective methods.
ISO 14068-1 defines "carbon neutrality" as a state of being carbon neutral. The IPCC distinguishes between
carbon neutrality, a condition in which CO emissions are balanced by CO removals, and GHG neutrality, in
2 2
which all GHG emissions are balanced by GHG removals.
Although these two terms differ in their focus, both aim to promote the reduction of GHG emissions. Overall,
the "net zero" definition in IWA 42 provides a more comprehensive and integrated concept, focusing not
only on CO removal but all GHG removal and focusing on human-led removals, applying to the entire
supply chain. Meanwhile, "carbon neutrality" in ISO 14068-1 is more focused on balancing CO , although its
definition aligns with comprehensive GHG neutrality.
This document provides use cases focusing on achieving net zero emissions for cities and communities
as a key step toward net zero carbon cities in response to climate change and the need for global carbon
neutrality.
4.4 Elaboration of ten themes contributing to net-zero
This clause identifies ten themes to organize and collect use cases for pathways toward net zero carbon
cities. These themes align with the six objectives and twelve sustainability issues provided in ISO 37101.
Through these themes, this document gathers use cases to provide practical strategies and references for
cities aiming to achieve the goal of net zero emissions.
By referring to 4.2 as well as standards such as ISO/TS 14092, ISO 14064-1, ISO 14068-1 and IWA 42, primary
sources of GHG emissions are identified across all key sectors: energy, industry, agriculture, forestry, land
use, transportation and construction. These GHG emission sources are incorporated into the ten themes for
two rounds of case collection. Each theme provides use cases with targeted reduction practices, practical
experiences, and possible lessons to share with cities.
The ten themes are:
— Theme 1: Governance and regional coordination: This theme encompasses government commitments
to achieving net zero carbon cities through regional collaboration and governance improvements.
Strategies include regional and local planning, policy and regulatory development, target and indicator
setting, implementation schemes, oversight and assessment, evaluation and periodic adjustments, and
community engagement. Additionally, it involves communication and fostering cultural awareness.
— Theme 2: Local actors, partners, participants or citizenship initiatives: This theme encompasses-
strategies for local governments, community organizations, and stakeholders to achieve net zero carbon
cities. It emphasizes collaboration, community engagement, education, and environmental stewardship.
In essence, it underscores the importance of fostering robust collaborative partnerships between localities
and cooperative entities to collaboratively identify and tackle the underlying factors contributing to the
reduction of GHG emissions. This endeavour necessitates extensive engagement from the community
and the public, the establishment of cooperative governance frameworks, the enhancement of civic
environmental education, the encouragement of volunteer initiatives, the nurturing of social innovation
and the reinforcement of local environmental stewardship.
— Theme 3: Industry and sustainable production and consumption: This theme encompasses strategies in
the industrial sector to promote sustainable production and consumption for net zero carbon cities. Key
measures include technological innovation, energy efficiency and sustainable consumption patterns.
These strategies encompass technological innovation, widespread application of energy-saving
equipment, dual optimization of energy structure and production processes, as well as advocating and
practicing the optimization and upgrading of consumption patterns, with the aim of effectively reducing
dependence on high energy-consuming products.
— Theme 4: Energy: This theme encompasses GHG emission reductions in the energy sector. It involves
phasing out high-carbon energy, improving energy efficiency, and promoting renewable energy and
digitalization technologies. By developing renewable energy and improving energy efficiency, it aims to
reduce GHG emissions. This includes energy efficiency, solar energy, wind or geothermal energy, electricity,
renewable energy utilization, energy digitalization, clean electricity and energy diversification.
— Theme 5: Construction: This theme encompasses GHG emission reductions in construction through
green building practices, upgrading existing structures, and using sustainable materials. It includes
planning, design and infrastructure improvements. By using low-carbon building materials and energy-
saving designs, it directly participates in GHG emission reductions and helps reduce GHG sources in the
construction sector. This includes planning and design, operation and infrastructure.
NOTE Countries and regions define green buildings differently. This document collects several examples below to
aid in understanding the concept.
United States The U.S. Environmental Protection Agency (EPA) considers green buildings as practices that are
environmentally responsible and resource-efficient throughout a building's entire life cycle, from site selection,
design, construction, operation, maintenance, renovation to demolition. This practice expands and complements the
considerations of economy, practicality, durability, and comfort in traditional architectural design.
China China's Green Building Evaluation Standard (GB/T 50378) clearly stipulates that green buildings refer
to buildings that maximize resource conservation (energy conservation, land conservation, water conservation,
and material conservation), protect the environment, reduce pollution throughout their life cycle, provide healthy,
applicable, and efficient living spaces, and coexist harmoniously with nature.
UK The British Building Research Establishment (BRE) developed the BREEAM in 1990. Although it does not
explicitly define green buildings, it evaluates the environmental performance of buildings throughout their life cycle.
According to the comprehensive score, buildings are divided into four levels: Pass, Good, Very Good and Excellent.
Europe The European Union does not have a unified definition of green buildings, but the Energy Performance of
Buildings Directive (EPBD) stipulates that all new buildings in the EU were "nearly - zero energy buildings" from 2020.
A net zero emission building means that the building has a very high energy performance level, extremely low energy
consumption, and all energy comes from renewable energy sources, with no GHG emissions from fossil fuels.
— Theme 6: Transportation: This theme encompasses reducing urban GHG emissions in urban transportation
by promoting low-emission vehicles, optimizing logistics and enhancing public transport. It emphasizes
energy efficiency and reducing fossil fuel dependence. This includes public transportation, electric and
hybrid vehicles, infrastructure development and mobility.
— Theme 7: Agriculture, forestry and other land uses: This theme encompasses reducing urban GHG
emissions and increasing urban carbon sinks through sustainable agricultural practices such as crop
rotation and cover cropping, and through the protection and restoration of forests, wetlands and other
ecosystems. It includes precision agriculture, forest management and ecological agriculture.
— Theme 8: Circularity: This theme encompasses reducing waste and emissions while improving resource
efficiency through reducing, reusing and recycling materials. It emphasizes that practicing a circular
economy helps to reduce the demand for new resources, thereby reducing emissions from extraction and

5.2.1 Beijing Future Science City (China): Practices for reduction and management of GHG
emissions in "Energy Valley"
5.2.1.1 Overview
BFSC is a hub for Beijing's efforts to establish a globally influential national science and technology innovation
centre, located in northern Beijing. The 'Energy Valley' covers 10 squares kilometres in the eastern section
of BFSC, designed to accommodate around 100 000 residents. Development began in 2009.
The Energy Valley is one of the first green ecological demonstration zones in Beijing and serves as a pilot
city for ISO 37101. From the beginning, BFSC has actively implemented national climate change strategies,
focusing on "low-carbon" development principles.
BFSC serves as a model for China and an important strategic initiative for Beijing in its efforts to achieve the
China’s 'Dual Carbon Goals,' aiming for carbon peaking by 2030 and carbon neutrality by 2060. By the end of
2023, approximately 4,4 million m of green buildings had been constructed within the Energy Valley, which
also hosts the country's first 'carbon-neutral theme park.' Nearly all energy technology companies in BFSC
are adopting low-carbon technologies, such as the national power investment corporation's net zero carbon
energy park, which showcases a smart, net-zero carbon power plant. By 2020, substantial reductions in GHG
emissions were achieved.
5.2.1.2 Benefits and objectives
a) Economic benefits:
1) Facilitating the development of advanced energy industries: The Energy Valley fosters economic
growth by attracting over 300 high-tech energy enterprises, driving innovation in Beijing's energy
sector.
2) Improving energy utilization efficiency and reducing costs: Significant resource conservation and
reduced energy consumption have been achieved through initiatives like energy-saving lighting
and renewable energy generation technologies.
b) Social benefits:
1) Attracting businesses and talent to the region, enhancing residents' well-being: Hundreds of
enterprises from various sectors have been attracted to BFSC, employing tens of thousands of
talented professionals.
2) Elevating the brand influence of BFSC: As one of the first green ecological demonstration zones in
Beijing and as the pilot city for ISO 37101, BFSC enhances community well-being by attracting talent
and promoting environmental awareness.
3) Increasing public awareness of environmental protection: The establishment of a "carbon-neutral
theme park" has encouraged active participation from citizens and tourists, with over 660 000
visitors recorded to date.
c) Environmental benefits:
1) Reducing GHG emissions and promoting carbon sequestration: In 2020, through initiatives such
as distributed photovoltaics and wind power, organizations in the Energy Valley reduced GHG
emissions by over 8 000 tons.
2) Improving the quality of air, water and soil in the region: This was accomplished by creating a
314-hectare waterfront park and establishing a green ecological corridor along the Wenyu River. As
a result, green coverage reached an impressive 84 %, and the water quality in the river significantly
improved.
5.2.1.3 Measures and methods
a) Emphasizing navigation by indicators and standards:
BFSC has established a comprehensive green and low-carbon indicator framework to guide GHG emission
reduction, involving a top-level design and the establishment of a green and low-carbon indicator framework
with 42 indicators, along with a green and low-carbon implementation scheme and a series of specific plans.
This framework includes specific low-carbon indicators, such as tons of GHG emissions (CO ) per
$ 1 000 000 GDP is less than 110 tCO per million USD and renewable energy utilization rate is greater
than 20 %. According to this framework, BFSC has conducted a top-level design for green and low-carbon
implementation scheme in the Energy Valley, which includes a management system guidance covering
planning, construction and operations throughout the entire life cycle of projects.
NOTE Tons of GHG emissions (CO ) per $ 1 000 000 GDP is less than 110 tCO per million USD: This means that
2 2
the ratio of total carbon dioxide (CO2) emissions from the construction, municipal, and transportation sectors within
the entire BFSC area to its GDP (measured in millions of dollars) is less than 110 tons. Renewable energy utilization
rate is greater than 20 %: this indicates that the proportion of renewable energy consumption in the total energy
consumption within the entire BFSC area exceeds 20 %.
b) Strengthening the role of plannings:
BFSC has created low-carbon plans based on the indicator framework and its implementation scheme, aiming
for low-carbon development in both master and detailed planning. In 2014, BFSC was the first industry park
in China to develop a low-carbon development plan, which uses a model to assess sustainability capabilities.
This plan includes a GHG emissions inventory and provides strategies, measures, and actions aimed at
reducing GHG emissions.
c) Exploring management methods:
BFSC has implemented an effective management system to promote green and low-carbon practices,
throughout all stages of development. Clear responsibility agreements have been established for developers
and other participating entities, ensuring stricter oversight during both the construction and the operational
phases. For projects undertaken by developers, ten ecological indicators have been integrated into land
grant conditions. Among these, seven indicators including the certification levels of green building and
energy – saving compliance rates for public buildings – are directly aligned with the goals of achieving a net
zero carbon city.
d) Establishing strong organizational leadership:
The administration committee of BFSC is responsible for overseeing, coordinating, supervising and
managing all activities related to green and low-carbon development. To further enhance these efforts, a
sustainable development department has been established to handle the implementation of indicators,
develop technical standards, conduct assessments and evaluations and
