Investment Rating - The report indicates a challenging outlook for SDG investments, particularly in least developed countries (LDCs), where investments are expected to fall by over 25% [3][9][31]. Core Insights - International investment in SDG-relevant sectors, excluding renewable energy, has stalled since 2015, with foreign investors sponsoring only one-fifth of infrastructure projects in developing countries [2][4]. - Preliminary data for Q1 2024 shows an 11% decline in the number of projects compared to the 2023 average, although the total value of these projects increased by 7% due to large-scale projects [3][9]. - The distribution of international SDG investments remains uneven, with 18 developing economies not receiving any internationally financed SDG projects since 2015 [4][11]. - The Belt and Road Initiative (BRI) has become a key driver of SDG investments, particularly in Africa, where it accounts for a third of all investments in social infrastructure sectors [8][31]. Summary by Sections International Investment Trends - Since 2015, the total number of international projects in SDG-related sectors has grown by 25%, primarily driven by renewable energy projects [3][14]. - The average number of SDG-related projects increased by around 20% over the last decade, but investments in water and sanitation (WASH) have halved [4][14]. Regional Disparities - Africa has consistently attracted the fewest international projects related to the SDGs, despite having a higher share of SDG-related projects compared to total international projects [16][20]. - In Latin America and the Caribbean, the total number of SDG-related projects increased by 45%, driven by a threefold increase in renewable energy investments [16]. Role of Multilateral Development Banks (MDBs) - MDBs play a crucial role in attracting foreign private investment for infrastructure projects, participating in about 5% of all project finance deals aligned with the SDGs [7][26]. - MDBs are more involved in LDCs, contributing to nearly a quarter of international human capital projects and around one-fifth of infrastructure and renewable energy initiatives [26][28]. Major Investors and Projects - Top sponsors in the renewable energy sector include Enel (Italy), Engie (France), and EDP Energias (Portugal) [35][38]. - Significant projects include a $35 billion health sector development in Egypt and two green hydrogen power plants in Oman valued at $5 billion and $6 billion [9][31].
