"Without You" remains Carey's biggest hit across Europe. In the British Isles, where Carey had yet to score a number one hit, "Without You" made its UK chart debut at number one where it remained for four weeks in total. In the UK, "Without You" was Carey's only number-one solo hit although she has since topped the charts with her collaboration with Westlife: "Against All Odds" in 2000, until Carey scored a second number-one solo hit with "All I Want For Christmas Is You" in 2020. "Without You" was certified platinum in the UK with combined sales and streams of 600,000. It was a runaway success across Europe, in which it topped the European Hot 100 Singles chart for two weeks. "Without You" reached number one for ten weeks in Switzerland; eight weeks in Austria and Sweden; seven weeks in Belgium; six weeks in Poland, five weeks in Ireland and the Netherlands; four weeks in Germany; and two weeks in Scotland, where Carey's success had previously been limited. The song also peaked at number two in France and Denmark, while in Norway it peaked at number three. "Without You" was certified platinum in Germany and Austria by IFPI, and gold in France by SNEP.
