What MBA or sustainability-focused master's programs in Germany and France would be suitable for my profile, given my master's in Public Policy and significant work experience?

Your Public Policy master's is an advantage here, not a gap to work around. You already understand institutions, regulation and governance, so the real educational gap most programs would fill is business, finance or management implementation skills layered on top of that policy foundation, not another policy degree.

HEC Paris vs ESSEC vs ESCP: Which Sustainability Track Fits a Policy Background

Why an MBA Might Serve You Better Than Another Master's

• ESMT Berlin MBA: accepts at least three years of experience and pairs sustainability with strategy and leadership, best if you want a genuine management transition.
• HEC Paris MBA: its class averages around six years of experience and includes a dedicated sustainability concentration.
• Mannheim Master in Sustainable Business and Technology: a 24-month part-time option if you want to stay employed while studying.

My Advice

Check prerequisites carefully before you fall in love with a program's ranking. TUM's sustainability masters, for example, expects prior coursework in business, economics and quantitative methods that a Public Policy degree alone will not cover, while HEC's sustainability master welcomes any bachelor's discipline. If your priority is staying employed during the degree, the Mannheim part-time route is worth a serious look before you assume a full-time MBA is the only path.
