Hello,
Looking at the manual entry for guix download [0], we can see:
guix download verifies HTTPS server certificates by loading
the certificates of X.509 authorities from the directory
pointed to by the SSL_CERT_DIR environment variable (see
X.509 Certificates), unless --no-check-certificate is used.

You can either use your operating system's certs directory
(usually /etc/ssl/certs), or install the nss-certs guix package,
as shown on the man page for X.509 Certificates [1] and export
the related environment variables to tell programs to use it:
$ guix package -i nss-certs
$ export SSL_CERT_DIR="$HOME/.guix-profile/etc/ssl/certs"
$ export
SSL_CERT_FILE="$HOME/.guix-profile/etc/ssl/certs/ca-certificates.crt"
$ export GIT_SSL_CAINFO="$SSL_CERT_FILE"

Hope that helps.
