I can't really understand the logic in this. If anything, CL has more going for it for production usage, like ANSI standarization and many high-performance compilers.
Clojure has the advantage of targeting the JVM and Js runtimes. These are two most popular runtimes for writing web apps currently. Clojure can also be easily integrated into existing projects on these platforms.
Your Common Lisp code can also target the JVM runtime by compiling using the ABCL implementation (free, mature). It is ANSI compliant, so your code will work straight away with no change. ABCL also allows easy calling of Java libraries.
Furthermore, not only JVM: other CL compilers let you target the LLVM. And of course you also have native compilers like SBCL which produce blazingly fast code.
