Brundtland's hallmark political activities have been chronicled by her husband, Arne Olav Brundtland, in his two bestsellers, "Married to Gro" (ISBN 82-516-1647-6) and "Still married to Gro" (ISBN 82-05-30726-1).
Maja 2007 je generalni sekretar ZN Ban Ki-moon imenoval Brundtlandovo, Ricarda Lagosa (bivšega čilskega predsednika ), in Han Seung-soo (nekdanjega južnokorejskega zunanjega ministra) za sodelovanje kot posebnih odposlancev ZN za klimatske spremembe.
