In Asus's case, the company's pursuit of green design has resulted in the implementation of much more stringent controls than called for in the EU's Restrictions on Hazardous Substances directive (the RoHS applies to six hazardous substances; Asus has implemented controls on 57) and an intense focus on energy conservation and efficiency.
以華碩奉行的「綠色設計」為例，除了在有毒物質的管控上較歐盟法規 RoHS 嚴格好幾倍外（RoHS 管控 6 種有毒物質，華碩卻自行管控 57 項），在節能、高效率上更有一項獨門絕活。
