One article to understand: The top four carbon exchanges in the world in 2023

The earth's temperature continues to rise, heat waves are sweeping across Europe and Taiwan, and news such as forest fires have dominated international news headlines. "Reducing carbon emissions" has become a new trend for individuals, business organizations and even countries, and "carbon exchanges" have begun to appear continuously in recent years.

A new generation of credit lines: CO2e

People (or organizations) who cause pollution can purchase "carbon rights" to offset the emissions they release into the air. Each credit is equal to "one ton of carbon dioxide equivalent (CO2e)". In other words, when an individual purchases a carbon credit, it can offset one ton of its own carbon dioxide emissions.

What is carbon trading? What is carbon offset? Carbon trading is the process of buying and selling carbon credits with the goal of reducing carbon dioxide emissions that contribute to global warming, and carbon exchanges are the vehicle for this mission. And carbon offsets represent the actual removal of carbon dioxide from the atmosphere. This removal can be achieved in a variety of ways, such as planting trees, capturing it directly from the emission source, or capturing it in the atmosphere. People with projects that remove some of their carbon emissions can sell those CO2 reductions as carbon credits.

Compliance carbon market VS voluntary carbon market exchange

Before discussing the carbon exchange, we will first mention the "compliance carbon market" and "Voluntary Carbon Market Exchange VCM, Voluntary Carbon Market" - the "compliance carbon market" mostly originates from national development or the "compliance carbon market" of U.S. state governments. Regulations that mandate the reduction of emissions", examples include the European Union's Emissions Trading System (EU ETS) or California's cap-and-trade scheme in the United States, where the government assigns maximum emission limits to each company. Emitters can then buy or sell carbon rights based on the emissions they produce and their allowance limits.

In contrast, voluntary carbon markets (VCM) operate without government regulation. However, it has exploded in recent years as the Paris Agreement calls on businesses to achieve strict net zero targets.

In the Voluntary Carbon Market (VCM) exchange, individuals and companies can purchase carbon rights to offset the carbon dioxide emissions they release. Many carbon rights buyers and sellers are now trading through digital carbon exchanges, including many. Few people prefer to use blockchain technology to conduct carbon token transactions.

 2022 TOP 4 Carbon Exchanges

In Europe and the United States, there have long been companies or individuals who have purchased carbon rights directly from developers who sell them. Now, there are more carbon rights buyers and sellers conducting "carbon token transactions" through blockchain technology. Although there is currently no unified global carbon trading market, trading plans and various trading platforms have been launched in several regional markets. Let’s take a look at the “TOP 4 Carbon Exchanges in 2022” compiled by the website.
