MySustainableCorner – September 2026

This month in a nutshell

• For her landmark concert series in Paris, Céline Dion has established a single residency instead of embarking on a traditional world tour, drawing 528,000 attendees, a third of whom are international. This 'residency' business model is becoming an industry standard: Adele designed a custom-built, temporary stadium for a 10-night exclusive run in Munich in 2024, while Harry Styles’ 2026 US tour will be consolidated into a 30-date exclusive residency in New York. Carbon accounting firm Greenly estimates the carbon footprint of this event at approximately 400,000 metric tons of CO2. While this static touring model reduces production logistics and crew travel costs, the event’s overall carbon footprint remains heavily driven by audience transit.
• To achieve carbon neutrality by 2050, Spain is committed to a systemic transition, aiming for a 100% renewable power mix driven by the large-scale scale-up of solar, wind, and green hydrogen. To deliver on this ambition, the country reached a key milestone in September 2026 with the issuance of a new green bond. The proceeds from this debt issuance will finance an eligible green project portfolio valued at €18.6bn.
• EDF recently raised €1bn through a green bond issuance to finance the lifetime extension of its nuclear power plants in France. This transaction further integrates nuclear energy into the green finance market, alongside more traditional sectors such as renewables and clean transportation. Under the EU Sustainable Finance Taxonomy, nuclear activities can be classified as environmentally sustainable subject to strict criteria, thereby enabling such projects to be funded through green debt instruments.
