Background of carbon neutrality: In recent years, the trend of carbon neutrality has been growing. If you search for "carbon neutrality" on the Internet, you will find that there are national-level carbon neutralities. For example, Japan and South Korea announced 2050 carbon neutrality. Neutralization, to carbon neutrality at the food, clothing, housing and transportation level in public life, such as: carbon-neutral meals, carbon-neutral shampoo, carbon-neutral marathons, etc. As the public attaches great importance to carbon reduction, countries and enterprises , individuals have begun to set carbon reduction goals and plan reduction actions, and carbon neutrality is the carbon reduction goal currently adopted by most entities. In order to cope with the impact of extreme climate, entities around the world have invested money, manpower, and time in carbon reduction. However, substantial carbon reduction is not an easy task and is difficult to implement in most cases. Therefore, "carbon offset" is very important for carbon neutrality. and played an important role. According to the definition of carbon neutrality in PAS 2060:2014, "the greenhouse gas emissions related to the subject matter during a specified period result in no net increase in greenhouse gas emissions in the atmosphere." Entities can achieve carbon neutrality by reducing and offsetting their carbon footprint through "self-reduction" and "external offsets". The "self-reduction" part is particularly important. It must be reduced to the point where it can no longer be reduced. At this time, the emissions that cannot be reduced will be offset through "external offsets". "Self-reduction" is usually achieved by investing in new technologies, new equipment, and new management methods. In practice, it is often a step-by-step reduction. Therefore, carbon neutrality is essentially a long-term carbon management plan. painting, a reduction plan should be planned and properly managed
