Antigua and Barbuda completed its TNA in 2023. It has prioritized its key sectors, assessed barriers and developed actions plans to drive future technology uptake and diffusion.
Antigua and Barbuda consists of two principal islands, as well as a number of smaller islands. Tourism is a major economic sector, contributing more than half of annual GDP, and the marine and coastal environment is particularly important. The agricultural sector is also an important part of the country’s economy, with major crops, including fish, cotton, livestock, vegetables and pineapples.
Antigua and Barbuda face significant environmental challenges linked to climate change and human activity. Rising sea levels and coastal erosion threaten beaches, infrastructure, and tourism, the nation’s main economic sector. Coral reefs and marine ecosystems are degrading due to ocean warming, pollution, and overfishing. Freshwater scarcity is a persistent issue, as the islands rely heavily on rainfall and desalination. Deforestation and habitat loss further endanger biodiversity, while hurricanes and droughts are becoming more intense and frequent. Strengthening climate resilience, promoting sustainable tourism, and protecting coastal and marine environments are essential for the country’s environmental and economic future.
Buildings, water and transport sectors were chosen as priorities for the TNA process. The initial step aimed at prioritising adaptation and mitigation technologies for Antigua and Barbuda, and identifying and assessing climate-smart technologies that would aid in achieving targets outlined in the INDCs, increasing overall resilience to the negative impacts of climate change and supporting the national development agenda.
