{{main|Insulate Britain protests}}
In 2021, several sections of the M25 were disrupted after the home energy and insulation campaign group [[Insulate Britain]] blocked junctions including Nos.&nbsp;3 ([[Swanley]]), 6 ([[Godstone]]), 14 (Heathrow), 20 ([[Kings Langley]]) and 31 ([[Lakeside Shopping Centre|Lakeside]]). A spokesman for [[the AA]] said the actions were counterproductive, as they would cause increased vehicle emissions owing to delays, as well having a negative effect on the economy.<ref>{{cite news|url=https://www.bbc.co.uk/news/uk-england-beds-bucks-herts-58543603|title=M25 junctions blocked by Insulate Britain campaigners|work=BBC News|date=13 September 2021|access-date=13 September 2021}}</ref><ref>{{cite news|url=https://www.theguardian.com/environment/2021/sep/13/climate-protesters-arrested-after-blocking-m25-junctions-in-rush-hour|title=Climate protesters arrested after blocking M25 junctions in rush hour|newspaper=The Guardian|date=13 September 2021|access-date=13 September 2021}}</ref> 92 people were arrested following the first incident on 13 September, followed by a further 70 two days later.
