時至今日，面對紛繁複雜的環境、社會和治理（ESG）指標和日益豐富的ESG實踐，ESG已不再是企業的邊緣議題。 以往企業通常根據不同評級機構的標準來提升其ESG評級。然而，全球約有600家不同的ESG評級機構，各自標準不一，導致評級結果不一致，這意味著即使企業在ESG方面投入大量精力，也可能獲得不同的評級結果。

學術界通過「政商學」有機結合實現對ESG發展的積極影響，並將成果傳導至政界和商界。香港大學賽馬會環球企業可持續發展研究所所長何國俊認為，跨界合作的模式之一為政府提出相關需求或搭建平台，由學術界針對性承擔科研任務，提供解決方案並為企業所用。政府亦適當提供科研資金或行政簡化，促使科研成果轉化落地以至商品化，幫助企業在市場競爭中不斷進步。

觀察近年來全球氣溫變化情況，相對於上世紀五、六十年代，赤道周圍的溫度上升幅度不大，溫度上升幅度大的反而是像北極這樣的高緯度地區。而這些高緯度地區長期冰雪覆蓋，所以溫度上升導致冰雪融化，從而導致海平面急劇上升。2017年發表在Science上的一篇文章表明，地表平均溫度上升超過2度以後，超額死亡造成的社會經濟成本是最主要的一部分，隨著溫度持續升高，死亡人數就會大幅度上升。

漢朝宗室大臣兼文學家劉向在《說苑．臣術》篇中將人臣分為十二種類型，六為正，六為邪，其中「諛」便是「六邪」之一。篇中將其描述為「主所言皆曰善，主所為皆曰可，隱而求主之所好而進之，以快主之耳目，偷合茍容，與主為樂，不顧其後害，如此者，諛臣也」，意指那些認為君主說的話都是好的、君主的行為都是對的，只會投其所好、阿諛奉承，助長君主的逸樂而不顧嚴重後果的馬屁精。
