Tacoma GHG Inventory and Climate Environmental Plan
Greenhouse Gas Inventory
Accounting to identify actions for a better & more just Tacoma
Client
City of Tacoma
Population
217,827
Schedule
2020-2021
The Problem
The City of Tacoma and Tacoma Public Utilities committed to net-zero community emissions by 2050 in 2019, but between 2016-2019 Tacoma’s GHG emissions increased by 16% while the population grew by only 3%.
The Problem
How can Tacoma meet its climate targets to align with the Paris Agreement?
53%
projected increase in population
56k
increase in # of households
*between 2019-2050.
The Solution
SSG supported Tacoma to update its greenhouse gas (GHG) inventory in alignment with the Global Protocol for Community-Scale GHG Emissions Inventories (GPC). A customized GHG Inventory Tool was developed to organize and tabulate all relevant data sources, making future updates straightforward. The tool’s outputs also meet international disclosure requirements.
Employing ScenaCommunity, SSG then modeled several scenarios to identify 64 actions across four of the largest emitting sectors: industry, buildings, transportation, and waste. The resulting climate action plan, the Tacoma Climate Action Report, was approved by council in 2021.
The Outcome
Tacoma’s GHG Inventory identified:
1.6M
MtCO2 GHG emissions
18
GHG emissions sources across 10+ municipal sectors
The price of not taking action, both in economic terms and in the potential cost of human health and life, particularly for Tacoma’s most vulnerable populations, is not only fiscally irresponsible but morally unacceptable.
