Banning mercury-based light sources by September 2021 would save more than 300 TWh of electricity by 2035 in the EU, according to the European Commission’s own assessments in July 2020 as it mulled a ban on mercury in lamps under to RoHS Directive. However, no decision has been proposed to date. New calculations on the costs of delayed EU decision have been carried out by CLASP.
With one year of regulatory delay, Europe loses €5.6 billion in cost savings due to excess energy use and adds 570 kg to its mercury pollution burden. As the delay lengthens, the cost goes up.
