We present a general thermodynamic framework for the low-dissipation limit. In the case of an iso-thermal engine, which converts chemical work into mechanical work, this theory predicts an efficiency at maximum power η* identically equal to 1/2. For multi-bath thermal machines, we derive bounds for efficiency at maximum power, namely ηrev/2 ⩽ η* ⩽ ηrev/(2 − ηrev), where ηrev is the efficiency of the corresponding reversible scenario.
