The economy of Antigua and Barbuda is particularly dependent on tourism, which accounts for 80% of GDP. Like other island nations, Antigua and Barbuda are particularly vulnerable to the effects of climate change, such as sea level rise,  and increased intensity of extreme weather like hurricanes, which have direct impacts on the island through coastal erosion, water scarcity, and other challenges. As of 2019, Antigua and Barbuda has a 0% individual income tax rate, as does neighboring St. Kitts and Nevis.
