“We only know about people who are not coming.”
In video footage filmed by the Welsh parliament, the Queen accused those leaders of hypocrisy.
“It’s really irritating when they talk, but they don’t do,” she remarked.
Earlier, the Queen’s grandson Prince William also issued a call for climate action, blasting the recent rise of space tourism in a BBC interview.
Ms Jones brought up the comments with the Queen during their conversation.
“Exactly, it’s a time for doing…and watching your grandson on the television this morning saying there’s no point going to space…” Ms Jones said.
“…we need to save the earth,” the Monarch added. “Yes, I read about it.”
The Queen’s unscripted remarks follow comments this week from Prince Charles urging Australia’s Prime Minister to attend the event.
Scott Morrison has not committed to travelling to Glasgow, but SBS News understands he is “highly likely” to travel to Glasgow.
Last month, he said travelling to the event would be a “significant undertaking” due to the two-week quarantine he would have to undertake on his return.

Mr Morrison has travelled to the G7 and New York and Washington in the past six months, quarantining at either the Lodge or Kirribilli house on his return.

Other world leaders have yet to confirm their attendance at the Glasgow event, including Chinese President Xi Jingping, Russian President Vladmir Putin and Brazillian President Jair Bolsonaro.
The Queen’s most recent remarks are receiving widespread coverage across the British tabloids.
The Daily Mirror front page featured the headline “GREEN QUEEN”, while the Daily Express reported “QUEEN VENTS FRUSTRATION” at world leaders for “dithering” over climate summit.
