Climate change is heating up West Africa's cocoa belt - Climate change is increasing temperatures year-round in West Africa, impacting cacao quantity and quality (February 2025)

KEY FACTS

● Climate change, due primarily to burning oil, coal, and methane gas, is causing hotter temperatures to become more frequent in the four West African countries responsible for producing approximately 70% of the world’s cacao — the key ingredient in chocolate.

● Analysis of daily maximum temperatures during the past decade shows that climate change added at least three weeks above 32°C (89.6°F) annually during the main cacao crop season (October-March) in Côte d'Ivoire and Ghana. Such temperatures are above the optimal temperature range for cacao trees.

● Over the same time period, climate change added just over two weeks above 32°C annually during the main crop season in Cameroon and more than one week in Nigeria.

● In 2024, human-caused climate change added six weeks’ worth of days above 32°C in 71% of cacao-producing areas across Côte d'Ivoire, Ghana, Cameroon, and Nigeria.

● While many factors, such as precipitation and insect-borne infections, can affect cacao trees, excessive heat can contribute to a reduction in the quantity and quality of the harvest — potentially increasing global chocolate prices and impacting local economies in West Africa
