Caroline Lucas, the only Green MP, has said she will take over as the parliamentary group's chairman, after Mr Corbyn said he had relinquished the role due to time pressures.
Ms Lucas paid tribute to her predecessor and insisted that parliamentary support for disarmament was growing.
She said: "Jeremy's been a passionate and effective advocate for nuclear disarmament in Parliament for many years and I'm proud to be taking over from him.
"There is a growing cross-party consensus on nuclear disarmament with the Labour Party leadership joining the Green Party, SNP and Plaid Cymru in opposition to renewing Trident."
Mr Corbyn stood down from his position as a vice-chair of CND and became vice-president after winning the Labour leadership race last September.
