Climate change disruptions to push coffee prices higher across supply chain, says GlobalData

Across major coffee origins, rising temperatures, irregular rainfall, and more extreme weather events are reshaping what coffee can be grown, where it can be grown, and how reliably it can be delivered.

The result is a more fragile supply chain: volatile harvests for farmers, uncertainty in raw material availability for manufacturers, and higher prices—along with reduced consistency—for consumers.

For hot coffee manufacturers, ready-to-drink brands, and café chains, climate disruption is now a procurement and operations challenge, not just a farming issue, according to GlobalData, a leading intelligence and productivity platform.

Coffee yields are increasingly threatened by warming conditions, especially for arabica, which makes up more than half of global coffee production and dominates many specialty and premium products. Arabica grows best within a relatively narrow climate range, with ideal mean annual temperatures between 15°C and 24°C (59°F–75°F), often found at higher elevations where conditions are cooler and more stable.

As temperatures rise, areas that once produced high-quality beans are becoming less suitable, and farmers are seeing more days of extreme heat that stress trees, reduce flowering, and limit cherry development. Climate Central estimates that leading coffee-growing countries responsible for 75% of the world’s coffee supply now experience an average of 57 additional coffee-harming heat days each year due to the climate crisis, with El Salvador among the most affected, recording 99 additional days of harmful heat annually.

Industry projections suggest the threat is not temporary. Rabobank forecasts that around 20% of current worldwide Arabica-growing areas could become unsuitable for cultivation by 2050, meaning production may shift geographically and become increasingly concentrated in fewer viable zones. This not only threatens total output but also increases the risk of disruption when extreme weather hits the remaining suitable regions.

Katamaneni Greeshma Kasturi, Consumer Analyst at GlobalData, comments: “If suitable growing zones shrink and production concentrates in fewer regions, supply shocks become more likely—and the ripple effects on pricing and availability can be amplified. Quality is also at risk. Higher temperatures can accelerate ripening, giving beans less time to develop sugars and aromatic complexity. Excess rain during harvest increases the likelihood of fermentation defects and mold, while sudden changes in humidity complicate drying and storage, raising defect rates and quality variation. In practical terms, climate change is affecting not just how much coffee is produced, but also how predictable and repeatable its flavour and performance are.”

When harvests fall unexpectedly, exporters may limit sales, and contracts become harder to fulfil, forcing manufacturers to find alternative origins or grades at short notice. Even when supply is available, beans can be more expensive or have a different quality profile than what brands have built their products around, driving changes in blending, reformulation, and roasting. In many cases, manufacturers may lean more on robusta, which is generally more heat-tolerant than arabica but has different flavour characteristics and can alter the sensory profile of finished products.

Consumers feel the impact most clearly through price. The FAO reported a nearly 40% price surge in 2024, driven largely by supply-side disruptions linked to unfavourable weather. However, consumers also pay in other ways, including reduced choice when certain origins or grades become harder to secure, fewer limited releases, discontinued premium lines, and occasional stock-outs—particularly for niche coffees. Over time, as brands adjust sourcing and blends, the “baseline” taste of mainstream coffee may gradually shift.

Kasturi adds: “Adaptation is possible, but it requires investment. Farmers are experimenting with shade-grown systems and agroforestry to cool microclimates, conserve moisture, and buffer temperature extremes. Meanwhile, research institutions and industry groups are also developing hybrids and varieties that can better tolerate heat and drought, resist pests, and still deliver strong cup quality. Yet these solutions take time to scale, and smallholder farmers—who produce much of the world’s coffee—often lack access to finance, technology, and training, making targeted support essential.”

For manufacturers, resilience increasingly means diversifying sourcing, strengthening long-term relationships with producers, investing in traceability and climate-risk monitoring, and planning for volatility as a standard operating condition rather than an exception. The future stability of coffee will depend not only on climate trends but also on how quickly the industry adapts in ways that maintain quality and reduce disruption for global markets.

Kasturi concludes: “Climate change is steadily transforming coffee production by shrinking suitable growing areas, increasing weather-driven yield volatility, and undermining quality consistency—especially for arabica. These pressures cascade through the supply chain, raising costs for manufacturers and consumers while reducing availability and choice. Although adaptation strategies exist and are already being tested, the pace and scale of investment—particularly for smallholder farmers—will determine whether the industry can maintain a reliable supply and preserve the quality profiles that consumers and manufacturers depend on.”
