Younghusband was elected President of the Royal Geographical Society in 1919, and two years later became Chairman of the Mount Everest Committee which was set up to coordinate the initial 1921 British Reconnaissance Expedition to Mount Everest. He actively encouraged the accomplished climber George Mallory to attempt the first ascent of Mount Everest, and they followed the same initial route as the earlier Tibet Mission. Younghusband remained Chairman through the subsequent 1922 and 1924 British Expeditions.
