Bottom Line on Climate Policy Terminology

The document defines fundamental climate policy terminology, distinguishing between market-based mechanisms like carbon taxes and cap-and-trade programs, and explaining concepts such as offsets, adaptation, and complementary policies.

• Carbon pricing is a market-based approach designed to discourage greenhouse gas (GHG) emissions by making it expensive to release them into the atmosphere. This can be achieved through a carbon tax, which provides a certain price but uncertain total emission reductions, or a cap-and-trade program, which ensures a certain level of total emissions through a maximum limit (cap) but results in an uncertain market price.
• Under cap-and-trade systems, emissions allowances—which grant the right to emit a specific amount of GHGs—can be distributed via allocation (given directly to specific sources or non-regulated parties) or through auctions to the highest bidders. Auctions can generate revenue for programs that help communities adapt to climate change or mitigate economic impacts on low-income consumers.
• Regulation of GHG emissions can occur at different points: upstream (e.g., oil refiners), downstream (e.g., coal-fired power plants), or through hybrid approaches. Additionally, cost-containment mechanisms, such as price ceilings (safety valves), banking unused allowances, or using offsets, are used to reduce market volatility and economic distress.
• The document distinguishes between several supportive climate strategies: offsets are verified emission reductions that compensate for emissions elsewhere; early action refers to reductions made before they are legally required; and complementary policies, such as renewable electricity standards (RES), are regulations that reinforce GHG reductions in specific sectors.
• The document clarifies the distinction between adaptation, which involves adjusting human and natural systems to minimize the harmful impacts of climate change, and mitigation, which focuses on reducing GHG emissions to minimize human impacts on the climate system.
