Environmental codes are regulations and guidelines designed to protect the environment and promote sustainable practices. They cover various areas, including air and water quality, waste management, and land use. These codes help ensure that businesses and individuals comply with laws aimed at reducing pollution and conserving natural resources. Governments and organizations often develop environmental codes to address specific local or global issues. For example, the Clean Air Act in the United States sets standards for air quality, while the Convention on Biological Diversity aims to protect ecosystems worldwide. By following these codes, communities can work towards a healthier planet.
