Figure 10: This function approving multiple green energy certificates.
These two functions in figure 11 manage the issuing of certifications for green energy requests.
The issue function allows the issuance of a single certification directly to a specified address without
requiring a separate manual approval process. The address (_to), the value, and any additional data
are provided, and the function returns a certification ID after validating the request.
The issueBatch function is designed for batch processing of multiple certificates at once. It takes

streamlining the certification process by avoiding multiple manual steps.
