After 1988 she specialised in news reading, including reading the news on Radio 4 breakfast Today programme, and reading news items on The News Quiz. The Daily Telegraph described her as "the supreme Radio 4 announcer whose warm yet slightly formal tones were once voted the nation's favourite". Green left Radio 4 in January 2013, and currently reads the classified football results on BBC Radio 5 Live and the World Service Sports Report, succeeding James Alexander Gordon. Her autobiography The News is Read was published by The Robson Press in 2014.
Green was educated at the independent Haberdashers' Aske's School for Girls in Elstree, followed by the University of Kent, where she gained a first-class BA in English and American Literature and was involved in university radio, before joining the BBC as a studio manager in 1978 at the World Service. She has said that "I wanted to be an actress, but I decided there were too many actresses around, so I joined the BBC."
After reading out letters for PM and You and Yours she became a continuity announcer, and then a newsreader in 1988. She was a regular newsreader for the Today programme and the comedy programme The News Quiz, and she has worked on PM and the Shipping Forecast. From 29 October 2005, she joined Chris Evans's Saturday afternoon show on Radio 2 to read phone numbers and announcements.
She was voted the "Most Attractive Female Voice on National Radio" in a poll by the BBC's Radio Times publication in 2002. Green has acknowledged the reliance lonely listeners place in her; her habit of wishing listeners "a peaceful night" led many to send her letters.
In addition to newsreading, Green has been a presenter, including for a programme on church music, a classical music concert series, and a series on World Service news bulletins. She presented Notes & Queries with Clive Anderson on television.
Between 2003 and 2006, Charlotte Green was unique in her pronunciation of the years between 2001 and 2009. She adopted the 'twenty-oh' method instead of 'two-thousand-and'. This was said to have sparked so many complaints that she reverted to 'two-thousand-and' in 2006.
She played herself in a 2005 radio episode of the The Hitchhiker's Guide to the Galaxy, and again played herself in 2008 in Simon Brett's radio detective drama Charles Paris. She has been impersonated by Jan Ravens reading out a double-entendres-filled shipping forecast on the BBC radio comedy show Dead Ringers. She signed a public letter of protest to the BBC Trust regarding cuts to the radio news service in 2007.
Green has on a number of occasions attracted some attention for inopportune giggling during on-air broadcasts. While announcing the death of American film and television writer Abby Mann Green laughed after what is believed to be the world's earliest recording, played during the preceding item, was described off-air as sounding like "a bee trapped in a bottle". Radio 4 hoped that Mann's family would realise that no harm was intended.
Green, and her colleague Harriet Cass left Radio 4, having opted for voluntary redundancy owing to reorganisation. Green's final news bulletin  was the 6 o'clock news on Friday 18 January 2013, though she hoped as a freelance to work on The News Quiz again.
Green joined Classic FM in 2013 and has presented Charlotte Green's Great Composers since 7 April. A keen supporter of Tottenham Hotspur FC, in August 2013 it was announced that Green will follow James Alexander Gordon as the permanent announcer of the Saturday football results on BBC Radio 5 Live. Green's new role, the first ever woman appointed to the post, began on 28 September 2013.
Green is an avid reader who enjoys going to the theatre, concerts and art exhibitions. She is also a Trustee of the University of Kent Development Fund.
