BBC viewers tuned in to Prince William's environmental awards ceremony The Earthshot Prize: Repairing Our Planet on Sunday evening.
The show saw five environmental solutions honoured with £1 million each to further their sustainability work, with Clara Amfo and Daniel Day Kim introducing the show.
The pair took to the stage at the outset of the BBC One programme to welcome sisters Chloe and Halle Bailey to perform a rendition of Feeling Good.
The event was also attended by David Beckham, Rami Malek and saw another performance from Ellie Goulding at the MGM Music Hall at Fenway in Boston.
Yet viewers at home were left unimpressed that the event saw presenters and attendees fly to the East coast city to attend the ceremony, particularly given its sustainability message, while recipients stayed at home to receive their awards virtually.
Taking to Twitter, one wrote: “Why did you fly celebrities from around the world to attend & leave the most important people at home because of the carbon footprint…”
A second chimed: “Let's save our planet by having a TV show, concert, black tie dinner event where singers, millionaires, fly in, have slap up meal, drinks, that's been imported from around the world.”
Another chimed: “Are all these celebrities going to jump back on gas guzzling planes, and fly halfway across the world, now they've finished lecturing us all?”
“No need to fly people across the world to Boston …,” another echoed.
Another wrote: "EarthShot Prize on BBC One seems a bit hypocritical.. loads of celebs flying thousands of miles for a glorified knees up….”
The event came amid a swirling crisis in the royal family, following the release of Meghan Markle and Prince Harry ’s explosive trailer for their highly anticipated upcoming Netflix documentary series.
The teaser trailer was released last week and has been met with a divisive response, with many criticising the timing amid Prince William and Kate’s US tour.
The Prince and Princess of Wales have received a mixed reception during their tour of Boston following the social media frenzy at the Netflix docu-series.
The teaser for the upcoming Netflix series shows never-before-seen photos of Prince Harry and Meghan, who are parents to Archie and Lilbet, as well as snaps from their childhoods.
The Sussexes have now been labelled ‘hypocrites’ for sharing Netflix footage taken near the late Queen's private apartments at Buckingham Palace.
While members of the public may be familiar with certain areas of the palace, the Queen and other royals' private apartments were completely off-limits, with barely any snaps being shared by the Royal Household.
However, the Duke and Duchess of Sussex have been blasted for filming during a trip to the United Kingdom – two years after announcing they would be moving overseas.
In the official trailer for their explosive Netflix documentary which airs on December 8, the pair can be seen walking towards a set of doors with two footmen preparing to open them.
On each side of the room, two chairs sit opposite one another with initials etched into them, signalling that they are the property of a monarch, while a box with ‘Her Majesty’ emblazoned on it sits on the windowsill.
However, many have noticed that the scene was filmed on the North Side of the palace, directly below the Queen's private apartments and is only used by the late Sovereign and members of the family.
