Ninth Circuit Upholds Washington State Decarbonization Law

• The Ninth Circuit Court of Appeals upheld the dismissal of PacifiCorp's lawsuit against the Washington state Department of Ecology.
• The court found that PacifiCorp failed to plausibly allege that similar entities were being treated differently in the application of decarbonization regulations.
• The ruling is a major victory for Washington state's efforts to reduce carbon emissions and transition to cleaner energy sources.
• The Climate Commitment Act sets ambitious decarbonization targets for utilities like PacifiCorp, which receives no-cost allowances for carbon emissions produced by electricity sold to Washington customers.

The court found that PacifiCorp failed to plausibly allege that similar entities were being treated differently in the application of decarbonization regulations.

In a significant ruling, the Ninth Circuit Court of Appeals has upheld the dismissal of PacifiCorp's lawsuit against the Washington state Department of Ecology. The lawsuit claimed that the department's enforcement of decarbonization requirements under the Climate Commitment Act violated the dormant commerce clause. However, the court found that PacifiCorp failed to plausibly allege that similar entities were being treated differently in the application of these regulations.

The ruling is a major victory for Washington state's efforts to reduce carbon emissions and transition to cleaner energy sources. The Climate Commitment Act sets ambitious decarbonization targets for utilities like PacifiCorp, which receives no-cost allowances for carbon emissions produced by electricity sold to Washington customers.

The dormant commerce clause is a constitutional provision that prohibits states from discriminating against out-of-state businesses. In this case, the court held that PacifiCorp's allegations did not meet the necessary standard for violating this clause. To succeed on such a claim, plaintiffs must demonstrate that similar entities are being treated differently in the application of state regulations. The Ninth Circuit's ruling underscores the importance of carefully evaluating these requirements when advising clients on compliance with Washington's decarbonization regulations.

The Climate Commitment Act has been at the center of several high-profile lawsuits in recent years. This latest ruling provides further clarity on the law's constitutionality and reinforces the state's authority to enforce its decarbonization requirements.

For lawyers advising clients on compliance with Washington's decarbonization regulations, this ruling has significant implications. The Ninth Circuit's decision underscores the importance of demonstrating that similar entities are being treated similarly in order to avoid violating the dormant commerce clause. This requirement is critical for utilities and other businesses seeking to navigate the complex regulatory landscape surrounding climate change mitigation efforts.

The ruling also highlights the need for careful analysis and planning when implementing decarbonization requirements. By providing a clear framework for compliance, Washington state's Climate Commitment Act has set an important precedent for other jurisdictions looking to reduce their carbon footprint.

Lawyers advising clients on compliance with Washington's decarbonization regulations should note that the Ninth Circuit has upheld the state's authority to enforce these requirements, and clients must demonstrate that similar entities are being treated similarly in order to avoid violating the dormant commerce clause.
