On 22 March 2018, Euronext endorsed the Task Force on Climate-related Financial Disclosures Recommendations and committed to further support transparency on climate-related risks and opportunities on financial markets. The signing of the recommendations took place during an opening bell ceremony in Brussels, held in presence of Michael Bloomberg (leader of the Task Force), and during which the Belgian State, the National Bank of Belgium and the Belgian Financial Services and Markets Authority (FSMA) also signed up to endorse the TCFD Recommendations. The bell ringing coincided with the “High Level Conference: Financing Sustainable Growth” organized by the European Commission in Brussels. This has been reiterated the 12 December 2020 when the 40 largest listed companies in France in the CAC 40 index, Euronext and the French Market Authority declared their support for the recommendations of the Task Force on Climate-Related Financial Disclosures (TCFD), demonstrating a commitment to building a more resilient financial system and safeguarding against climate risk through better disclosures. A 2020 TCFD Index is available on Euronext website. Sustainable Development Goals As an Official Partner of the Sustainable Stock Exchange Initiative (SSE) (1) , Euronext firmly commits to the UN’s “2030 Agenda for Sustainable Development” and thereby to all the 17 Sustainable Development Goals (SDGs), which were adopted in September 2015. The Sustainable Development Goals (SDGs) are a collection of 17 global goals set by the United Nations General Assembly in 2015 for the year 2030. They define global sustainable development priorities and aspirations for 2030 and seek to mobilize global efforts around a common set of goals and targets. The SDGs call for worldwide action among governments, business and civil society to end poverty and create a life of dignity and opportunity for all, within the boundaries of the planet. They explicitly call on all businesses to apply their creativity and innovation to solve sustainable development challenges. The SDGs have been agreed by all governments, yet their success relies heavily on action and collaboration by all actors.
