Editing London congestion charge (section)

====End of Greener Vehicle Discount====
In November 2012, TfL presented a proposal to end the Greener Vehicle Discount that benefited mainly vehicles with small diesel engines, that avoid the charge because their engines produce emissions of less than 100&nbsp;g/km of CO<sub>2</sub>.<ref>{{cite news|url=https://www.bbc.co.uk/news/uk-england-london-20400740|title=Congestion charge greener vehicles rule change planned |publisher=BBC News |date=11 December 2012|access-date=20 November 2012}}</ref> The proposal was approved by Mayor [[Boris Johnson]] in April 2013 and the Ultra Low Emission Discount (ULED) went into effect on 1 July 2013. The ULED introduced more stringent emission standards that limit the free access to the congestion charge zone to all-electric cars, some plug-in hybrids, and any car or van that emits 75&nbsp;g/km or less of CO<sub>2</sub> and meets the Euro 5 emission standards for air quality. {{As of|2013|07}}, there are no [[internal combustion]]-only vehicles that meet these criteria. The measure was designed to curb the growing number of diesel vehicles on London's roads. About 20,000 owners of vehicles registered for the Greener Vehicle Discount by June 2013 were granted a three-year [[Sunset provision|sunset period]] before they have to pay the full congestion charge. Other changes were the removal of the option to pay the charge in shops, and the penalty charge was increased to £10.<ref name=ULED>{{cite web|url=http://www.greencarcongress.com/2013/04/uled-20130424.html|title=London to introduce new Ulta Low Emission Discount for Congestion Charge scheme; countering dieselization|publisher=[[Green Car Congress]]|date=24 April 2013|access-date=24 April 2013}}</ref><ref>{{cite news|url=https://www.theguardian.com/environment/2013/apr/24/pollution |title=London tightens up congestion charge in attempt to drive out diesel |work=[[The Guardian]]|date=24 April 2013 |access-date=18 April 2015 |archive-url=https://web.archive.org/web/20150418174852/http://www.theguardian.com/environment/2013/apr/24/pollution |archive-date=18 April 2015 |url-status=live}}</ref><ref>{{cite web |url=http://www.thegreencarwebsite.co.uk/blog/index.php/2013/07/01/london-tightens-congestion-charge-exemptions/ |title=London tightens Congestion Charge exemptions |author=Faye Sunderland |publisher=The Green Car Website (UK) |date=1 July 2013 |access-date=1 July 2013 |archive-url=https://web.archive.org/web/20150216062939/http://www.thegreencarwebsite.co.uk/blog/index.php/2013/07/01/london-tightens-congestion-charge-exemptions/ |archive-date=16 February 2015 |url-status=dead}}</ref><ref>{{cite news|url=https://www.bbc.co.uk/news/uk-england-london-23125082|title=New green discount for the congestion charge comes in |publisher=BBC News |date=1 July 2013|access-date=2 July 2013}}</ref> The sunset period ended on 24 June 2016.<ref name=Sunset2016>{{cite web| url=http://www.nextgreencar.com/news/7701/congestion-charge-sunset-period-ends-today/ |title=Congestion charge sunset period ends today |first=Chris |last=Lilly |publisher=Next Green Car |date=24 June 2016 |access-date=29 June 2016}}</ref> In December 2018, a further tightening of the standards was announced, in part to bring standards beyond that of the ULEZ. This means that since April 2019 only vehicles which are Euro 6, emit up to 75 g/km of {{CO2}} and have a minimum 20 mile zero emission range have qualified for the discount. A further phase from October 2021 will mean that only [[zero-emission vehicle]]s ([[battery electric vehicle|pure electric vehicles]] and [[fuel cell vehicle|hydrogen fuel cell vehicles]]) can qualify, and the discount will be phased out completely from December 2025.<ref name=":0" />
