Oregon Court of Appeals finds state carbon reduction rules invalid.

The state Department of Environmental Quality said the ruling will not affect its ability to enforce carbon reduction rules.

The Oregon Court of Appeals decided Wednesday that a state program designed to limit and drastically reduce greenhouse gas emissions from fossil fuel companies is invalid.

The Oregon Department of Environmental Quality’s Climate Protection Program failed to comply, “or even substantially comply,” with disclosure requirements when adopting rules under the federal Clean Air Act, the Oregon Court of Appeals said.
