The Republic of Mauritius’ Third Nationally Determined Contribution (NDC 3.0) reaffirms its commitment to the Paris Agreement, despite contributing only 0.01% of global GHG emissions. As a Small Island Developing State (SIDS), Mauritius faces severe climate risks, including sea-level rise, coastal erosion, biodiversity loss, and more frequent cyclones. NDC 3.0 targets a 40% reduction in economy-wide emissions by 2035 compared to BAU, focusing on energy (60% renewable electricity, coal phase-out), transport electrification, waste-to-energy projects, and decarbonisation of aviation, ports, and manufacturing. Ocean-based carbon sinks and circular economy initiatives complement mitigation efforts.
Adaptation is central to NDC 3.0, addressing water scarcity, coastal vulnerability, agriculture, health, and social resilience. Measures include aquifer protection, desalination, smart irrigation, agroforestry, and climate-smart fisheries. Coastal zone management will rehabilitate 33 eroded sites using nature-based solutions like mangrove and coral restoration. Tourism will shift toward inland ecotourism, while health systems integrate early warning for climate-sensitive diseases. Social inclusion and gender-responsive strategies ensure vulnerable groups benefit from resilience-building. Financing needs for adaptation and mitigation total USD 11.3 billion by 2050, requiring international support, technology transfer, and capacity building.
