The Malta Resources Authority is a public corporate body set up in 2000 through the Malta Resources Act to regulate water, energy and mineral resources, to promote energy efficiency and renewables, and with responsibilities in oil exploration and climate change. The Regulator for Energy and Water Services Act, 2015, changed the MRA’s responsibilities mainly to registration and metering of boreholes, mineral resource regulation and climate change reporting and operation of the emission trading scheme.

Grant schemes, swimming pool licences and energy and water services licences are among the functions of the new regulator established under the Regulator for energy and water services - REWS;

Energy efficiency, renewable sources of energy, the water framework regulations (inland waters) and protection of groundwater are among the functions of the Sustainable Energy and Water Conservation Unit;
