Cap and trade system vs carbon tax

Those supporting a carbon tax argue that it is a better approach because it is transparent, minimizes the involvement of government, and avoids the creation of​.

An ETS — sometimes referred to as a cap-and-trade system — caps the total level of greenhouse gas emissions and allows those industries with low emissions to sell their extra allowances to larger emitters. By creating supply and demand for emissions allowances, an ETS establishes a market price for greenhouse gas emissions.

The cap helps ensure that the required emission reductions will take place to keep the emitters in aggregate within their pre-allocated carbon budget.

Important Similarities Between Cap and Trade and Taxes

A carbon tax directly sets a price on carbon by defining a tax rate on greenhouse gas emissions or — more commonly — on the carbon content of fossil fuels. It is different from an ETS in that the emission reduction outcome of a carbon tax is not pre-defined but the carbon price is. The choice of the instrument will depend on national and economic circumstances. Private entities or sovereigns can purchase emission reductions to compensate for their own emissions so-called offsets or to support mitigation activities through results-based finance.

Some 40 countries and more than 20 cities, states and provinces already use carbon pricing mechanisms, with more planning to implement them in the future. Together the carbon pricing schemes now in place cover about half their emissions, which translates to about 13 percent of annual global greenhouse gas emissions. Climate change is one of the greatest global challenges of our time.

We are already seeing changes in the climate that our current economies were built on. Fourteen of the 15 hottest years since record keeping began over years ago have been since the turn of this century. The intensity of extreme weather-related events has also increased. They warn of dangerous effects on agriculture, water resources, ecosystems, and human health if countries do not take action.

Already, studies suggest that about 1. That means action now. Carbon pricing is an essential part of the solution. The economic arguments for action are also compelling. Delaying action, the IPCC warns, will only raise the costs. Statement Putting a Price on Carbon June 3, Climate change poses one of the greatest global challenges and threatens to roll back decades of development and prosperity.

The latest report from the United Nations Intergovernmental Panel on Climate Change makes clear the importance of putting a price on carbon to help limit the increase in global mean temperature to two degrees Celsius above pre-industrial levels. Governments are taking action.

Carbon Pricing | Union of Concerned Scientists

In , about 40 national and over 20 sub-national jurisdictions have already implemented or scheduled emissions trading schemes or carbon taxes. Together, these jurisdictions account for more than 22 percent of global emissions. Many more countries and jurisdictions are advancing preparation for pricing carbon. Together, these represent almost half of global GHG emissions. Corporations are responding.

The Political History of Cap and Trade

A growing number of companies are already working within carbon pricing systems and are developing expertise in managing their emissions. Others are incorporating greenhouse gas reduction targets in their business planning. In , over companies worldwide publicly disclosed to CDP that they already use carbon pricing as a tool to manage the risks and opportunities to their current operations and future profitability.

Businesses see that carbon pricing is the most efficient and cost effective means of reducing emissions, leading them to voice support for carbon pricing. The momentum is growing. Pricing carbon is inevitable if we are to produce a package of effective and cost-efficient policies to support scaled up mitigation. Greater international cooperation is essential.

Governments pledge to work with each other and companies pledge to work with governments towards the long-term objective of a carbon price applied throughout the global economy by:. We invite all countries, companies and other stakeholders to join this growing coalition of the working. The Carbon Pricing Leadership Coalition brings together leaders from government, private sector, academia, and civil society to expand the use of carbon pricing policies.

It also serves as a platform for countries to share knowledge and work together to shape the future of cost-effective climate change mitigation. Contacts Angela Churie Email.

Governments set the price of pollution while markets determine the amount of pollution — companies can pollute and pay the tax or reduce emissions to avoid the tax.

There are carbon taxes in other countries but not in the U. In practice, the tax burden might be passed along to consumers. If a refinery that produces heating oil pays a tax for emitting carbon, customers might end up paying higher home heating oil prices. To some economists, this is not a bug but a feature: higher prices would lower demand for carbon-intensive fuels. Cap-and-trade policy puts a cap on overall amounts of pollution.

Governments set the amount of allowable pollution, markets set the price. The idea is the emissions cap is divided into credits and those credits are distributed across companies that pollute.

Companies that pollute under the cap can sell credits to entities that pollute more. Part of the appeal is that as the cap lowers over time, so does the number of credits, incentivizing companies to pollute less. So far, the U. The strategies go by different names, but in practice they may not be that dissimilar — the devil, as always, is in the details.

Stavins assesses the state of the practice in a recent National Bureau of Economic Research working paper. There are other economic levers that can be pushed or pulled — subsidies for clean fuel and energy-efficient cars, for example, or technology standards on machines that burn fossil fuels. But economists generally agree that carbon taxes and cap-and-trade offer the best bang for the buck. Raise the price of gasoline, people buy less of it. Raise it enough and they stop buying Hummers and start buying Priuses. So the economics is pretty clear, either cap-and-trade or a carbon tax can really blunt emissions.

The U. It seeks to reduce airborne sulfur dioxide and nitrogen oxides coming from power plants. Acid rain happens when those pollutants get into the atmosphere, then fall to the ground via moisture like rain or snow, contaminating waterways and crops. Another national cap-and-trade program was the NOx Budget Trading Program, which operated during the s and sought to reduce nitrogen oxides from power plants during the summer.

The program prevented nearly 2, summertime deaths each year in participating states, most of them along the east coast, according to a analysis in the American Economic Review. No national cap-and-trade program has come close to passing Congress in the decade since. My view is, if it was possible to demonize cap-and-trade as a tax, it is highly likely that it will be possible to demonize a carbon tax as a tax. States have since taken up the cap-and-trade baton. However, that analysis finds the initiative had a causal effect only on reductions of sulfur dioxide emissions, not nitrogen oxides.

This could be because power plants emit much more sulfur dioxide than nitrogen oxides — more data makes it easier to pinpoint causation, explains one of the authors, University of Massachusetts Amherst economist Nathan Chan. The authors looked at daily data on megawatts produced from power plants in the continental U. The initiative has so far achieved its main goal of reducing power plant emissions in participating states, according to the paper.

Carbon Tax vs. Cap and Trade

Participating states also reduced overall electricity generation, in particular from coal plants. Some environmental benefits were offset by increased natural gas energy production in neighboring states, like Pennsylvania and Ohio. This concept is called leakage, and it works like this: the cost of carbon credits can lead an energy producer in a cap-and-trade state to raise prices.

A competitor just over the state border might sell energy for cheaper, or an energy producer might move out of a cap-and-trade state. As far as the Regional Greenhouse Gas Initiative is concerned, that offset appears to be less severe than previously estimated. The way the program works is a little inside baseball, but a big part of it is that companies buy something called allowances at state auction. Allowances let companies emit pollutants, and companies can also buy pollution credits from entities that reduce greenhouse gases or store carbon. California takes revenue from those auctions and reinvests the money into climate-friendly programs.

Schmalensee and Stavins note in their paper that cap-and-trade alone is not enough to address climate change:. Its utilities are largely on board with addressing climate change, even through regulation. Then there is the free-rider problem, which extends well beyond California. There is, right now, no prospect of an enforceable, international cap-and-trade system that could put a meaningful dent in global carbon emissions. There are too many hurdles to mention, but one of them is that countries would probably want higher emissions caps for themselves, but lower emissions caps for the rest of the world, as the late Harvard economist Martin Weitzman explained in a June article in Environmental and Resource Economics.

In other words, countries want to reap the benefits of carbon reduction without paying the price.
