Chu was one of the winners of the 1997 Nobel Prize for physics. Even earlier, when he was the head of the electronics research group at Bell Labs, he advocated solving the problem of climate change through "carbon neutrality" (for the amount of carbon produced by each person, there should be corresponding carbon reduction measures, such as planting trees, so that net carbon emissions are zero).
朱棣文是 1997 年諾貝爾物理學獎得主之一，而他早年在 AT＆T 貝爾實驗室（Bell Labs）擔任電子研究小組負責人時，就曾主張以「碳中和」（碳平衡，意即每人排放多少碳，就以種樹等相對方式來抵銷，讓碳排放量為零）來解決氣候變遷的問題。
