Starbucks’ Path to Carbon-Neutral Coffee: New Tactics & Tech

Coffee demand has soared over the past 30 years. Production has risen by 50% during that period, according to the International Coffee Organisation.

Today, coffee fuels a US$200bn global industry, with three billion cups enjoyed each day. Yet, with consumption forecasted to triple by 2050, the environmental costs of coffee production are becoming harder to ignore.

Traditionally linked to deforestation and labour issues, the coffee industry faces growing pressure to adopt sustainable practices, with consumers demanding more transparency and legislation tightening on products linked to deforestation.

Starbucks, as the world’s largest coffeehouse, is taking bold steps to address its impact on the environment by aiming for carbon-neutral coffee by 2030.

Sustainability at the source

Starbucks’ sustainability strategy begins on the farms it partners with around the world, working with 400,000 farmers and purchasing about 800 million pounds of coffee annually—5% of the world’s supply.

To meet its carbon-neutral coffee goal, Starbucks has committed to cutting water usage in green coffee processing in half by 2030.

Since 2004, Starbucks has pioneered its Coffee and Farmer Equity (CAFE) Practices programme, a broad ethical sourcing standard. CAFE Practices, built on 200 specific criteria, assesses economic transparency, social responsibility, environmental leadership and product quality across the company’s supply chain.

This programme not only sets standards but also helps Starbucks identify and understand the challenges farmers face, using these insights to support improvements across its coffee-growing network.

“Starbucks has a tremendous opportunity to impact the lives and livelihoods of farmers and their communities,” says Michelle Burns, Executive Vice President for Global Coffee & Sustainability at Starbucks. 

To support farmers in meeting these standards, Starbucks pays premiums above market rates, rewarding farms that meet CAFE requirements. It also established its first farmer support centre in Costa Rica, the first of 10 globally, now serving more than 200,000 farmers with resources and training in areas like soil management and crop disease resistance.

Hacienda Alsacia, Starbucks’ research farm in Costa Rica, functions as a vital research hub where agronomists have developed six climate-resistant coffee varieties that Starbucks distributes at no cost through its open-source agronomy programme.

By 2025, the company aims to provide 100 million of these resilient coffee trees, with more than 80 million already planted in El Salvador, Guatemala and Mexico, as well as 53 million seedlings in Colombia.

Future-focused initiatives

Beyond agricultural support, Starbucks is exploring sustainable technologies to manage resource use, aiming to reduce water consumption in coffee processing by 50% by 2030. The eco-wet mill is one of the company’s significant investments, engineered to cut water use by up to 80% in the coffee milling process.

With 1,300 eco-mills already in use worldwide, Starbucks envisions scaling these across its supply chain to reduce water consumption significantly.

Starbucks also focuses on community-based education initiatives. The Granos de Esperanza (Grains of Hope) programme in Colombia, for instance, helps farmers adopt sustainable techniques and gain climate knowledge.

Located in Narino, this real-time agricultural lab provides 100 farmers with tools like eco-pulpers, which reduce water use. The techniques tested here take inspiration from Hacienda Alsacia’s work, aligning with Starbucks’ carbon-neutral goal by helping farmers adapt their practices to changing environmental conditions.

Starbucks’ wider sustainability mission includes forest conservation and biodiversity protection. To advance these goals, the company plans to conduct a biodiversity impact assessment of its coffee supply chain by the end of fiscal year 2025.

This analysis aims to provide Starbucks with clearer insights into its environmental impact, guiding its strategies to protect ecosystems more effectively.

Leading in sustainable coffee

Starbucks is positioning itself as a leader in sustainable coffee production, striving to shift its entire supply chain toward practices that reduce carbon output.

Michelle highlights Starbucks’ commitment to sustainability, emphasising the trust that the company has built with consumers over the years: “People have watched us working hard to do the right things, find solutions and take great care of farmers and their communities for decades. They grant us an amount of trust and opportunity to help lead the discussion around ensuring a sustainable future of coffee for all.”

As Starbucks progresses toward its 2030 goal, it represents a model for the coffee industry, demonstrating that sustainable sourcing and carbon reduction can coexist with a thriving business.

Through eco-friendly innovations, direct support for farmers and consistent evaluation of its practices, Starbucks aims to redefine the future of coffee, setting a powerful example for sustainability across the global coffee sector.
