Cap-and-trade programs, on the other hand, set a cap on emissions and therefore provide quantity certainty-but price fluctuations under the trading market structure can provide a less solid basis for business planning decisions. Carbon taxes provide price certainty, as entities subject to the tax know how much they’ll have to pay per ton emitted-but simply setting a tax rate doesn’t guarantee any particular level of emissions reductions. Banking and borrowing gives firms more flexibility in methods of compliance and reduce the costs of meeting a cumulative emissions target.Ĭarbon taxes and cap-and-trade programs primarily differ by the type of certainty they provide. When banking and borrowing take place, emissions during a specific year may be greater or less than the number of allowances issued in that year, but over time, the emissions and allowances are balanced. Some cap-and-trade programs include provisions for the banking and borrowing of allowances over time: permits issued in one year can be submitted to account for emissions in later years (banking), and permits for future years can be issued and used in the current year (borrowing). Allowances can be traded, and the sales and purchases (supply and demand) of allowances yield a market price for allowances-essentially the price of one ton of CO₂ emissions. The limited, government-controlled supply of allowances “caps” the total amount of emissions.

Allowances can be distributed in a number of ways: they can be directly allocated to firms or facilities (a concept called free allocation of allowances) or sold through auction markets. In a cap-and-trade program, the government issues a limited number of emissions allowances (also known as permits), each of which grants the holder the right to emit one ton of CO₂. A $1 tax per ton of CO₂ is equal to a $3.7 tax per ton of carbon, because carbon constitutes roughly 3/11 of the weight of CO₂.Ī cap-and-trade program limits the total amount of CO₂ that can be emitted by certain facilities. Because CO₂ emissions from the combustion of fossil fuels are proportional to the carbon content of the fuel, a carbon tax is, in effect, a tax on CO₂. Carbon pricing policies traditionally take two forms: carbon taxes and cap-and-trade programs.Ī carbon tax is a price set per ton of carbon or, more commonly, per ton of CO₂ emitted.
