The state failed to ’substantially comply' with disclosure requirements in the rule-making process.

The Oregon Court of Appeals on Wednesday invalidated the state’s landmark Climate Protection Program (CPP), which aimed to slash greenhouse gas emissions from fossil fuel companies by 90 percent by 2050.

The state’s rulemaking failed to “substantially comply” with the requirements for disclosure when adopting rules under the federal Clean Air Act of 1970, a three-judge panel of the state appeals court said.
