The document proposes a two-step emissions target mechanism—periodic evaluation and triggered policy changes—to ensure a U.S. carbon tax meets national GHG goals. It suggests four types of trigger responses: automatic tax rate adjustments, increased government spending for emissions reduction, activating 'back-stop' regulations, or streamlined legislative modification. Additionally, it identifies three categories of complementary policies to enhance cost-effectiveness: support for low-carbon innovation (RDD&D), consumer energy savings incentives, and policies targeting 'uncovered' emissions or non-climate co-benefits.

The document examines how a national carbon price would induce emissions reductions across the U.S. economy, with the most immediate and significant impacts occurring in the electricity sector. It argues that while U.S. Energy Information Administration (EIA) forecasts are conservative, empirical evidence from places like British Columbia suggests that carbon pricing can drive substantial behavioral changes and technological innovation. The authors advocate for a combination of carbon pricing and complementary policies, such as R&D funding and energy-efficiency standards, to overcome market barriers and achieve a target of reducing emissions by more than 80 percent by 2050.

The report argues that large-scale US dairies can reach net zero emissions within five years by integrating specific technologies and practices, potentially increasing annual net returns to $1.9 million per dairy. Key strategies include precision agriculture, feed additives to reduce enteric methane, and anaerobic digesters that convert manure and organic substrates into renewable energy and fertilizers. The analysis emphasizes that while technologies exist, achieving these goals requires significant policy shifts, such as expanded water quality trading markets and improved EPA processing of renewable fuel pathways.
