Our Work
Oregon has multiple paths to cutting emissions nearly in half by 2030
Transformational Integrated Greenhouse Gas Emission Reduction (TIGHGER) Plan
Client
Oregon Department of Energy, State of Oregon
Population
4,200,000 (2020)
Schedule
2021–2023
The Problem
Oregon has long been a national leader in climate action. It was the first state to eliminate coal from its electricity mix and was an early adopter of transportation electrification. Despite this progress, the state was 26% over its 2020 emissions target. The Oregon Department of Energy needed rigorous analysis to chart a faster, more ambitious path to its updated goals.
The Problem
How can a climate action leader accelerate its progress and cut emissions nearly in half within a decade?
61M
metric tons of greenhouse gas emissions in Oregon (2021)
45%
emissions reduction required below 1990 levels by 2035
The Solution
SSG built a customized, county-level energy and emissions model for Oregon. 15 existing programs and regulations were modeled, showing that their proper implementation is capable of meeting the 2035 target. SSG modeled 35 additional actions for buildings, transportation, energy, and industry, identifying two pathways that achieve the same goal five years earlier. The analysis quantified financial, health, and equity co-benefits for each action, giving Oregon’s Legislature the evidence and confidence needed to prioritize and accelerate climate action.
SSG led stakeholder engagement with nine state agencies and 95 public participants to develop and refine a list of potential emission reduction actions. The actions were modeled in two scenarios: Electrification and Hybrid (which incorporated alternative fuel options). 23 of the actions were the same in the scenarios while 12 actions were unique to each.. The analysis went beyond traditional least-cost methods, to quantify health, equity, and jobs co-benefits for each action to help decision-makers weigh the full value of Oregon’s climate investments.
The Outcome
SSG’s modeling showed Oregon that:
$47B
net financial benefit from implementing the identified actions
283k+
additional net job-years created through 2050
$74B+
in health savings to Oregonians by 2050
*as compared to a business-as-usual scenario, see Oregon TIGHGER Project Report, March 2023.
