The report evaluates 'post-harvest to grave' emissions for woody biomass residues in the Pacific Northwest and Alaska. It finds that alternatives displacing fossil fuels—such as industrial boilers, biochar, and integrated gasification—significantly reduce greenhouse gases, carbon monoxide, and fine particulate matter compared to on-site burning. Conversely, residential wood stoves and fireplaces often increase local air pollutants.

The Union of Concerned Scientists analyzed the potential effects of Washington's Initiative 937 (I-937), which would require large electric utilities to source 15 percent of electricity from eligible renewable resources by 2020 and pursue cost-effective energy conservation. Under an expected case scenario, the report projects that by 2025, I-937 would result in $1.13 billion in cumulative savings on consumer electricity bills, the creation of 2,000 new jobs, and a reduction of 4.6 million metric tons of annual CO2 emissions. The analysis indicates that renewable energy and efficiency investments would be cost-competitive with conventional fossil fuel resources, providing long-term price stability and economic development, including $2.9 billion in new capital investment. Sensitivity analyses suggest that even under pessimistic conditions—such as higher wind costs or the expiration of federal tax credits—the initiative would generally still yield long-term savings and environmental benefits.

The Union of Concerned Scientists (UCS) documents a pattern of scientific misconduct within the Bush administration, citing cases where political objectives overrode scientific evidence. Key examples include the disregard of environmental impacts in mountaintop removal mining, the denial of over-the-counter access to emergency contraception despite expert advice, and the manipulation of endangered species data for salmon, Florida panthers, bull trout, and trumpeter swans. The report also details the use of political litmus tests for scientific advisory panel appointments and recommends reforms to protect government scientists and ensure the independence of advisory committees.

The document argues that President Donald Trump's 2018 executive order to increase logging by 31 percent to prevent forest fires is misleading and dangerous. It asserts that large-scale industrial timber harvesting is associated with worse fires in some regions and that the primary drivers of worsening fires are climate change, excessive drought, high winds, and heat. The text claims the policy serves to expand the logging industry rather than address the environmental causes of wildfires.
