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.

Outcome

Key Takeaways

Oregon is on track if it stays the course.

SSG’s modeling confirmed that Oregon’s 15 existing climate programs and regulations are sufficient to meet the 2035 target, but only if they are fully resourced and implemented as planned. Two programs account for over 97% of the reductions needed: the clean electricity law (HB 2021) and the Climate Protection Program.

Climate action pays off.

SSG’s analysis quantified the full value of acting ambitiously. After accounting for capital investments, energy savings, and reduced maintenance, Oregon comes out $47 billion ahead. Including health benefits from cleaner air, such as fewer heart attacks, hospital visits, and premature deaths, the total benefit to Oregonians exceeds $120 billion by 2050.

Oregon can meet its 2035 goal five years early.

SSG’s modeling demonstrated that Oregon had two pathways to achieve its 2035 emissions target by 2030, consistent with IPCC science and the ambitions of its west coast neighbors. Both pathways identified shared a common core of 23 actions, with 12 further actions tailored to one pathway or another. Whichever route Oregon chooses, they must implement all actions of either pathway in order to achieve their accelerated goal.
