what is cap and trade 
cap and trade is a common term for a government regulatory program designed to limit or cap the total level of emissions of certain chemicals particularly carbon dioxide as a result of industrial activity proponents of cap and trade argue that it is a palatable alternative to a carbon tax both measures are attempts to reduce environmental damage without causing undue economic hardship to the industry understanding cap and tradea cap and trade program can work in a number of ways but here are the basics the government sets the limit or cap on emissions permitted across a given industry it issues a limited number of annual permits that allow companies to emit a certain amount of carbon dioxide and related pollutants that drive global warming other pollutants that contribute to smog can also be capped the total amount of the cap is split into allowances each allowance permits a company to emit one ton of emissions the government distributes the allowances to the companies either for free or through an auction but the government lowers the number of permits each year thereby lowering the total emissions cap that makes the permits more expensive over time companies have an incentive to reduce their emissions more efficiently and invest in clean technology as it becomes cheaper than buying permits companies are taxed if they produce a higher level of emissions than their permits allow they may even be penalized for a violation on the other hand companies that reduce their emissions can sell allowances trade them to other companies that pollute more they can also bank them for future use 1advantages and disadvantages of cap and tradethe cap and trade system is sometimes described as a market system that is it creates an exchange value for emissions since companies that have emissions credits can sell them for extra profit this creates a new economic resource for industries its proponents argue that a cap and trade program offers an incentive for companies to invest in cleaner technologies in order to avoid buying permits that will increase in cost every year it also motivates companies to fund research into alternative energy resources this process may lead to faster cuts in pollution since companies that cut their emission levels faster are somehow rewarded as can then sell their allowance to other companies because the government can decide to auction emissions credits to the highest bidder cap and trade is also a revenue source for the government since it has the power to auction emissions credits to the highest bidder this new revenue can cover infrastructure needs social programs be invested in cleaner technologies or it can even be a way to solve a budget deficit at the state or national level as a free trade system cap and trade gives consumers more choices as well consumers can choose not to purchase from companies that are out of compliance and do business with those that are trying to reduce their pollution levels finally the cap and trade system also has benefits for the taxpayers the government sells emission credits to businesses that need them the income generated helps to supplement the resources that taxpayers are providing the government opponents of cap and trade argue that it could lead to an overproduction of pollutants up to the maximum levels set by the government each year since allowable levels may be set too generously actually slowing the move to cleaner energy also emissions credits and even penalties and fines for exceeding the cap limit are usually cheaper than converting to cleaner technologies and resources this is the case for example for industries that use fossil fuels this means that cap and trade is not a real incentive for those industries to change their practices it s also argued that the trade mechanism is not always followed some credits are sold at auctions to the highest bidder or even given away this means it costs a company nothing to increase its emissions most industries don t have devices that help monitor and determine their amount of emissions this makes it relatively easy for businesses to cheat on their emissions reports for the cap trade system to be effective monitoring systems must be implemented so that enforcement can take place since renewable energy resources are still relatively new they are also expensive products sold by companies that conform to the cap rules tend to be more costly to produce affecting what consumers pay for them finally each country has different standards and maximum caps for emissions some may be very lenient and permit higher levels of pollution while others may be very strict unless a global cap and trade system is established it won t be effective globally and there may be little impact on the

in establishing a cap and trade policy is the ability of governments to impose the correct cap on the producers of emissions a cap that is too high may lead to even higher emissions while a cap that is too low would be seen as a burden on the industry and a cost that would be passed on to consumers there is also an overall lack of reliable data on emissions the estimates for past and current emissions as well as predictions for future emissions vary widely among industries a cap and trade system may be useless until accurate information on emissions is available which involves a costly process and can take years to complete 2apart from the lack of reliable emission data there are also many methodological challenges when it comes to applying an effective cap and trade system the difficulty to achieve an international consensus on emissions and caps since each country has different priorities or the high transaction and administrative costs involved among others finally predicting the long term effects and benefits of cap and trade initiatives is also a great challenge although cap and trade systems reduce emissions and can lead to faster cuts in pollution they also tend to increase the price of oil coal and natural gas in an effort to force companies to switch to alternative forms of energy these initiatives are expensive and impact negatively the economy cap and trade examplesin 2005 the european union eu created the world s first international cap and trade program with the goal of reducing carbon emissions in 2019 the eu estimated that there would be a 21 reduction in emissions from sectors covered by the system by 2020 during the administration of u s president barack obama a clean energy bill that included a cap and trade program was introduced in congress it was eventually approved by the house of representatives but never even got to a vote in the senate the state of california introduced its own cap and trade program in 2013 the program was initially limited to fewer than 400 businesses including power plants large industrial plants and fuel distributors its goal of reducing greenhouse gas emissions to 1990 levels by 2020 was successfully met in 2016 mexico is running a pilot cap and trade program that the country began in january 2020 this is the first emissions trading pilot program in latin america and it aims to move to full operations in 2018 the country committed to a 22 reduction in greenhouse gasses by 2030 3
