Projects

Metro commissioned EcoDataLab to prepare a comprehensive CBEI for the greater Portland region, in support of the 2030 Regional Waste Plan and the Comprehensive Climate Action Plan.

The project also included a Supply Chain Emissions Inventory (SCEI) analyzing Metro's own procurement emissions, providing the regional government with a complete picture of impacts from both community-wide and organizational activities.

See Metro's project page for the full published report, presentation, and resources.

In collaboration with Cascadia Consulting Group, Stockholm Environment Institute, and Kim Lundgren Associates, EcoDataLab prepared a consumption-based emissions inventory (CBEI) and report for King, Pierce, Kitsap, and Snohomish Counties, as well as the City of Seattle.

See the 2019 King County Communitywide Consumption-based GHG Emissions Inventory Report, published September 2022.

An updated version of the CBEI was prepared for King County in 2025, with a focus on updating the emissions factors and data sources used in the inventory. See the 2023 King County CBEI Report, published November 2025.

Working under C40 Cities, EcoDataLab prepared a CBEI for New York City, the New York City Household Consumption-Based Emissions Inventory, published April 2023.

This report was unique in that we also provided support to New York for developing the Integrated Citywide and Consumption Inventory (documentation here). The integrated inventory estimates the portion of consumption-based emissions that occur locally in New York City versus emissions that occur outside of the city — a first for CBEI methodology.

In 2023, EcoDataLab prepared a Community-Wide CBEI, a Corporate CBEI, a Buildings and Linear Infrastructure Analysis, and a public-facing CBEI Infographics Report for the City of Toronto.

The Community-Wide CBEI was the first instance of applying the US-based CBEI model to a Canadian community, and the report contained detailed discussions of how Toronto's existing emission reduction efforts align with CBEI-related emission reduction opportunities, as well as potential directions for future effort.

Toronto's Corporate CBEI developed Scope 3 procurement emissions, based on City budget data, and combined it with the existing municipal sector-based inventory to evaluate the impacts of city purchases of goods and services in comparison with other traditional categories of electricity, natural gas, and transportation fuels.

The Buildings and Linear Infrastructure Analysis evaluated emissions from construction activity occurring in the city, using building permit data for 2019 and capital budget data to estimate total impacts from construction.

The CBEI Infographics Report highlighted key findings of the Community-Wide and Corporate CBEIs and presented them in accessible, easy-to-understand infographics for public use.

As a result of this CBEI project, in October 2023 the Toronto City Council passed a recommendation to the City Manager to prepare reports on progress and action towards meeting Toronto's Cool Food Pledge and C40 Good Food Cities Declaration commitments, provide annual progress updates, and evaluate a plant-based purchasing program for City operations.

In collaboration with the University of Leeds and Sustainability Solutions Group (SSG), with advisory support from SEI and Norwegian University of Science and Technology (NTNU), EcoDataLab led the preparation of the C40 report "Cutting GHG emissions from consumption: Indicators are tools for action," published in October 2023.

This report — developed with a focus on New York City and London, but applicable to all cities — reviewed available data for tracking progress toward reducing consumption-based emissions. A key finding: cities don't need a full CBEI to get started. Instead, they can use actionable data indicators (ADI) — readily available, regularly updated data that tracks progress toward emission reduction or behavior change goals.
