GHG Protocol for Cities
Greenhouse Gas Protocol
City tool tracks, reduces greenhouse gas emissions.
The GHG Protocol for Cities costs $0 USD. Renewal costs $0 USD every 12 months.
Key Strengths
- Developed by globally respected institutions: WRI, C40 Cities, and ICLEI
- Aligns with international standards including IPCC guidelines
- Enables consistent, comparable GHG inventories across cities worldwide
- Supports integration with global climate reporting platforms (CDP, UN-Habitat)
- Free to use — no licensing fees for cities
- Backed by World Bank and major multilateral organizations
Ideal For
Best suited for city governments, municipal sustainability officers, and urban planners seeking a standardized, internationally recognized framework to measure and report greenhouse gas emissions. Particularly valuable for cities committed to climate action plans, net-zero targets, or participation in global initiatives like C40 or ICLEI networks.

Overview
The GHG Protocol for Cities is a framework for cities to measure and manage their greenhouse gas emissions. Launched by the World Resources Institute, C40 Cities, and ICLEI, it's rooted in the broader GHG Protocol, developed since the late 1990s. This program helps cities create inventories of their emissions, track progress, and set policies to reduce carbon footprints.
Key partners include influential global cities and organizations like the World Bank. The framework aligns with international standards, ensuring credible, transparent data. Many cities worldwide have adopted it, helping policymakers craft effective climate strategies.
For policies and certifications, it assists governments in validating their environmental impact. The initiative underscores the critical role cities play in combating climate change, providing tools to integrate sustainability into urban development.
Requirements & Verification
Evidence Requirements
Cities must compile emissions data across relevant sectors (energy, transportation, waste, industrial processes, etc.) following the GPC methodology. Documentation includes activity data, emission factors, data sources, and uncertainty assessments. Cities report at BASIC or BASIC+ tier levels depending on data availability. Submissions to platforms like CDP require structured inventory reports aligned with GPC requirements.
Prerequisites
Assessment Process
There is no formal exam. Cities prepare a GHG emissions inventory following the GPC (Global Protocol for Community-Scale GHG Emission Inventories) methodology, selecting either the BASIC or BASIC+ reporting tier. The inventory documentation is submitted to reporting platforms such as CDP for review. Third-party verification of inventory data is optional but recommended for cities seeking higher credibility.
Renewal & Compliance
The GHG Protocol for Cities framework does not impose a formal renewal cycle. Cities are encouraged to update their GHG inventories on an annual basis to track progress against targets and maintain reporting to platforms such as CDP. No formal recertification fee or mandatory renewal process is required.

Consider Alternatives If...
Cities or organizations seeking a formal individual professional certification with a credential or badge should look elsewhere, as this is a policy framework and accounting methodology rather than a personal credential. It may also be less suitable for small municipalities without dedicated sustainability staff or data infrastructure to conduct full emissions inventories.
