The number of certificates in a certificate chain can vary depending on the specific context and system being used. Typically, a certificate chain includes a root certificate, an intermediate certificate, and a leaf certificate (also known as an end-entity certificate). In some cases, there may be multiple intermediate certificates in the chain, and the number of certificates present can vary depending on the level of trust and security required for the system.

Some of the most recognized environmental certifications include:

1. ISO 14001:2015 for Environmental Management Systems,
2. LEED (Leadership in Energy and Environmental Design) for building and construction,
3. FSC (Forest Stewardship Council) for forestry and paper products,
4. Energy Star for energy efficiency,
5. B Corp for overall social and environmental performance,
6. Fairtrade for fair trade practices
7. EMAS (Eco-Management and Audit Scheme) for environmental management Keep in mind, different certifications are more recognized and important in different industries, regions, and sectors. It’s worth noting that this list is not exhaustive and many other recognized certifications provide information on environmental impact.
