In 2014, the State of California and the Canadian province of Quebec were able to connect their systems. In 2015, the provinces of Ontario and Manitoba agreed to join the connected system between Quebec and California.  On September 22, 2017, the premiers of Quebec and Ontario, as well as the Governor of California, signed the formal liaison agreement.  The American Clean Energy and Security Act (H.R. 2454), a law limiting the Emissions Trading System, was passed by 219 to 212 votes in the House of Representatives on June 26, 2009. The bill was introduced by the House Energy and Commerce Committee and introduced by MPs Henry A. Waxman and Edward J. Markey.  Political interest groups FreedomWorks and Americans for Prosperity, funded by brothers David and Charles Koch of Koch Industries, encouraged the Tea Party movement to focus on defeating the legislation.   Although Cape Town and Trade also gained an important foothold in the Senate thanks to the efforts of Republican Lindsey Graham, independent and former Democrat Joe Lieberman and Democrat John Kerry, the law died in the Senate.  Emission charges or environmental charges are a surcharge for pollution caused by the production of goods and services.
 For example, a carbon tax is a tax on the carbon content of fossil fuels, which aims to prevent their use and thereby reduce carbon dioxide emissions.  The two approaches are overlapping draft directives. Both can have a number of areas, regulatory points and price plans. They may be fair or unfair depending on how revenues are used. Both of these aspects have the effect of increasing the prices of goods (such as fossil fuels) for consumers.  A large cap-and-trade system auctioned upstream is similar to an upstream global carbon tax. Nevertheless, many commentators oppose both approaches. The cap-and-trade system is sometimes referred to as the market system. This means that it creates an emissions trading value. Its proponents argue that a cap-and-trade program encourages companies to invest in cleaner technologies to avoid the purchase of permits that will increase costs each year.
In order to increase flexibility and without an international agreement by 31 December 2009, the credits could be used in accordance with agreements with third countries. However, the use of these credits is not expected to increase the total beyond 50% of the necessary reductions. Such agreements would not be necessary for new projects launched in the least developed countries from 2013. Cape and trade differ from a tax in that it provides a high level of security on future emissions, but not by the price of these emissions (carbon taxes do the opposite).
