I will discuss new results on the formation of planets and the role of ice lines in planet formation. Pebbles play a crucial role both for the formation of planetesimals by particle concentration followed by gravitational collapse and for the subsequent rapid growth of planets by pebble accretion. The chemical composition of the pebbles depends strongly on the local temperature of the protoplanetary disc. Near ice lines, diffusion of vapour leads to efficient pebble growth. These large pebbles can trigger planetesimal formation, so that planetary seeds start to grow outside ice lines. I will show that the current location and mass of Jupiter are consistent with formation near the CO ice line.
