How Does Chocolate Production Affect the Environment?
The Sweet Treat with a Bitter Footprint
Chocolate is a global favorite—Americans alone consume about 3 billion pounds annually [Statista]. But behind that indulgence is an industry facing serious sustainability challenges: deforestation, child labor, water use, and now climate change. In fact, Hershey announced this week that it’s increasing chocolate prices due to rising costs linked to global cocoa shortages.
So, how exactly does chocolate production affect the planet, and how is climate change changing chocolate’s future?
How Chocolate Is Made
Chocolate begins with cocoa beans, grown on cacao trees, primarily in West Africa, which produces over 60% of the world’s supply. After harvesting, the beans are fermented, dried, shipped, and processed into cocoa butter and cocoa powder. Sugar and milk (in milk chocolate) add additional layers of environmental impact.
Environmental Impacts of Chocolate Production
1. Deforestation
Cocoa farming has historically driven deforestation in countries like Côte d’Ivoire and Ghana. Farmers often clear forests to expand plantations, threatening biodiversity and releasing carbon stored in trees. According to the World Cocoa Foundation, about 90% of West Africa’s original forests have been destroyed in the last century, partly due to cocoa cultivation.
2. Carbon emissions
A single bar of milk chocolate emits about 3.5 kg of CO₂e, largely due to dairy content and cocoa farming [Poore & Nemecek 2018]. Dark chocolate typically has a slightly lower footprint (around 2.9 kg CO₂e), but still significant when compared to plant-based snacks.
3. Water use
Chocolate is water-intensive: it takes about 17,000 liters of water to produce 1 kg of chocolate, primarily for growing cacao and sugar [Water Footprint Network]. This is higher than many staple foods.
4. Pesticides and soil degradation
Many cocoa farms rely on pesticides and monoculture farming, which can degrade soil health and reduce biodiversity. Without sustainable practices, this leads to long-term productivity declines.
Social Issues: Child Labor and Farmer Poverty
About two million children are estimated to work in hazardous conditions in cocoa production, mostly in West Africa [US Department of Labor]. Low wages push farmers to expand production unsustainably, creating a vicious cycle of poverty and environmental damage. Sustainable certifications like Fairtrade aim to address these issues, but adoption remains limited.
How Climate Change Is Impacting Cocoa
Cacao trees are highly sensitive to temperature and rainfall changes. They thrive in specific conditions: 20° north and south of the equator, with stable rainfall and humidity. Climate change is disrupting this balance:
Higher temperatures reduce yield and quality.
Erratic rainfall and droughts increase tree stress and disease risk.
Shifting growing regions may force farmers uphill or into forested areas, potentially causing more deforestation.
A study by the International Center for Tropical Agriculture predicts that by 2050, suitable cocoa-growing areas in West Africa could decline by up to 50% without adaptation.
Impact on chocolate prices
Hershey’s recent price increase reflects this reality. Cocoa supply shortages caused by droughts and disease outbreaks have already reduced production in Ghana and Côte d’Ivoire, contributing to higher costs globally.
Can Chocolate Be Sustainable?
Certifications and transparency
Look for certifications like:
Fairtrade – supports better wages and labor practices.
Rainforest Alliance – promotes sustainable agriculture and reduced deforestation.
Direct trade – often ensures farmers are paid higher prices directly.
Sustainable farming methods
Agroforestry: Planting cocoa alongside trees for shade improves biodiversity and reduces deforestation pressure.
Organic practices: Reduce pesticide use and improve soil health.
Climate-resilient crops: Breeding cacao varieties that withstand higher temperatures and drought.
Consumer actions
Choose dark chocolate: Less dairy content means lower emissions.
Buy from sustainable brands: Many companies are committing to deforestation-free cocoa supply chains.
Eat mindfully: Reducing overall consumption of resource-intensive foods, including chocolate, lowers personal footprint.

The Future of Chocolate
The future of chocolate depends on how quickly the industry adapts to climate change and addresses social issues. Companies are experimenting with:
Cocoa-free chocolate made from carob or fermentation-based cocoa substitutes.
Vertical farming and lab-grown cocoa to reduce deforestation.
Carbon-neutral certifications and regenerative agricultural approaches.
These innovations may keep chocolate on our shelves but also raise questions about taste, cost, and accessibility.
Conclusion: A Treat Worth Rethinking
Chocolate will likely never be a “low-impact” food, but better farming practices, transparent supply chains, and mindful consumption can reduce its footprint. Climate change is adding new urgency, as higher temperatures and extreme weather threaten global cocoa supply—and increase costs for companies like Hershey and ultimately, consumers.
Enjoying chocolate doesn’t have to stop, but it’s worth thinking about where it comes from and how often we consume it.
