Global regulations related to coal issues are becoming stricter as awareness of the environmental impact of coal use increases. The primary goal of these regulations is to reduce greenhouse gas emissions, particularly carbon dioxide (CO2), which are produced from coal combustion. Some relevant global regulations concerning coal issues include:

1. Paris Agreement: This agreement aims to limit the global temperature rise to below 2 degrees Celsius compared to pre-industrial levels. Countries that have signed the agreement commit to reducing greenhouse gas emissions, including from the energy sector, such as coal-fired power generation.
2. Kyoto Protocol Amendments: These amendments are part of the Kyoto Protocol, which regulates greenhouse gas emissions reductions in industrialized countries. Although not specifically targeting coal, it generally promotes emission reductions in the energy sector.
3. EU Industrial Emissions Directive (IED): This directive regulates emissions from large industrial installations, including coal-fired power plants. It sets strict emission limits for various pollutants, including sulfur dioxide, nitrogen oxides, and particulates.
