To descend from a fundamental theory to low energy phenomena one usually makes use of effective equations which capture the main quantum effects in a specified regime. A Hamiltonian procedure to derive effective equations is first illustrated by the example of an anharmonic oscillator and then applied to quantum cosmology. Extending this to full gravity demonstrates in which sense loop quantum gravity provides an emergence scenario for space-time from a microscopic theory.
