As part of the European Week of Regions & Cities, between 7-10 October 2019, the European Long-Term Investors Association co-organised the session 'Financing Europe's Sustainable Energy future' on Wednesday 9 October. This discussion focused on the contribution of National Promotional Banks and Institutions (NPBIs) to the financing of sustainable development in European territories, particularly from the perspective of two ELTI members: the Bulgarian Development Bank (BDB) & MFB Hungarian Development Bank as well as the Manchester Climate Change Agency and the European Commission (DG ENER).
