The analysis would argue against an economy-wide downstream cap-and-trade program (also difficult to manage), a stand-alone cap-and-trade program for major sources (as incomplete), and a GHG tax that is not part of a broader tax reform initiative (as politically impractical). The analysis suggests that the upstream cap-and-trade comprehensive approach and the sector-wide hybrid approach are the most viable alternatives to a national GHG reduction program. Cap-and-trade programs and carbon taxes can work well as long as they are designed to provide a strong economic signal for the transition to cleaner energy. However, there are a few differences. This answer Last update: 28.01.2013 Learn more about the project and suggest a question Report a bug in this answer A hybrid industry program with negotiable standards. This program combines a downstream cap-and-trade program for large sources in the energy and industrial sectors with improved product efficiency standards for end energy consumers, such as. B carbon dioxide (CO2) standards per kilometre for vehicles. Automakers could trade between their own product lines, among themselves and with companies subject to the downstream cap-and-trade program. For example, European countries have been running a cap-and-trade program since 2005. Several Chinese cities and provinces have had carbon caps since 2013, and the government is working on a national program. Mexico is implementing a cap-and-trade pilot program that the country launched on January 1, 2020. Inability to internalize externality costs. Economists have long recognized that some costs do not appear in the market prices of raw materials or goods, and that these costs can ultimately reduce the overall prosperity of the economy.
In the context of this book, environmental damage is the classic external cost. In recent decades, the electricity industry has begun to internalize the costs of air pollution and other environmental externalities by investing in pollution control equipment and switching to low-emission fuels and technologies. Greenhouse gases are the last external problem, with CO2 being the main pollutant in the electricity industry, although sulphur hexafluoride (SF6) and other greenhouse gas molecules are also found in the electricity sector. Cap-and-trade policies and carbon taxes would serve to internalize these externalities. However, in the next section, the authors discuss the limits of carbon pricing as an emissions reduction strategy and as an incentive to invest in efficiency. Tokyo, a city with a larger carbon footprint than many industrialized countries, introduced its own cap-and-trade system in 2010. The initiative applies to their most energy-intensive and carbon-intensive organizations and aims to reduce emissions by 25% below 2000 levels by 2020. A carbon tax also has a decisive advantage: it is easier and faster for governments to implement. A carbon tax can be very simple. It can build on existing administrative structures for fuel taxation and can therefore be implemented in a matter of months. In theory, the same is true for cap-and-trade systems, but in practice they tend to be much more complex. It takes longer to develop the necessary regulations, and they are more vulnerable to lobbying and loopholes.
The cap-and-trade system also requires the establishment of an emissions trading market. Banking/borrowing – Can the facilities save excess value for use in a subsequent year or “borrow” provisions for a future year? Banking and borrowing help avoid price spikes. Banking also offers a financial incentive to reduce emissions beyond what is required. However, borrowing can lead to supply bottlenecks in the coming years. Most programs allow you to bank, but not borrow. So what`s the best policy to reduce U.S. emissions? The cap-and-trade system has been successfully used in the United States to reduce emissions of sulfur dioxide and nitrous oxide, two key ingredients responsible for acid rain. Since the early 1980s, this cap-and-trade system has reduced acid rain emissions by almost half, resulting in a healthier environment. In some idealized circumstances, carbon taxes and cap-and-trade have exactly the same results, as they are both ways of assessing carbon.
In reality, however, they differ in many ways. WRI researchers recently analysed this question in our thematic article “Putting a Price on Carbon: Reducing Emissions”. We found that while there are legitimate reasons to favour one form of carbon pricing over the other, if it is well designed, a carbon tax or a cap-and-trade program may be at the heart of the United States. Efforts to reduce greenhouse gas emissions. A carbon tax imposes a tax on every unit of greenhouse gas emissions and incentivizes businesses (and households, depending on the scope) to reduce pollution if it costs less than paying the tax. Therefore, the amount of reduced pollution depends on the chosen amount of the tax. .
