Desalination, which produces usable water from saline water, has a higher LCW than processing groundwater or surface water. A 2020 study found that advances in decarbonization would reduce the levelized cost of water produced via desalination from €2.4 per cubic meter in 2015 (US$2.84) to €1.05 per cubic meter in 2050 (US$1.24).
