Global Study Maps the “Carbon Footprint” of Latin American Coffee

Dubai – Qahwa World

A comprehensive international study released in March 2026 has revealed a sharp disparity in the carbon footprint of coffee production across five major Latin American nations. This landmark report establishes the first precise scientific baseline—using primary data collected directly from farms—to address climate change challenges within the global coffee sector.

The study, conducted by Conservation International in collaboration with the Sustainable Coffee Challenge and Meo Carbon Solutions, analyzed supply chains in Brazil, Colombia, Honduras, Mexico, and Peru. The findings provide a “wake-up call” for the industry, highlighting how specific farming practices, particularly fertilization and waste management, dictate environmental impact.

  • The Emission Gap: Colombia Leads while Mexico Sets a Benchmark

Detailed data shows that coffee production in Colombia generates the highest greenhouse gas emission intensity, averaging 5.59 kg of carbon dioxide equivalent (CO2-eq) per kilogram of green coffee. Honduras followed with 4.87 kg. In Brazil, the results varied by variety, with Arabica recording 3.22 kg compared to 2.51 kg for Robusta.

Conversely, Mexico emerged as the country with the lowest emissions in the study group, averaging just 1.46 kg. Experts attribute this lower footprint to specific traditional farming practices, including greater reliance on natural shade and organic soil health.

  • Fertilizers: The Primary Climate Culprit

According to the extensive technical report, the most significant “hotspot” for emissions in Latin American coffee is fertilizer and nutrient application. In Colombia and Brazil, fertilization accounts for approximately 60% of the total carbon footprint. This is primarily due to the heavy use of nitrogen-based inputs, which release potent greenhouse gases when interacting with the soil.

In other regions, the drivers differ. In Peru, “crop residues” and unmanaged organic decomposition were identified as the primary sources of emissions. Meanwhile, in Honduras, the traditional wet processing of coffee cherries—specifically the management of wastewater at the farm level—contributes significantly to the national baseline.

  • A “Pre-Competitive” Global Alliance

The study is the result of an unprecedented “pre-competitive” alliance involving major global coffee brands, roasters, and suppliers. Giants such as Nestlé, Starbucks, and JDE Peet’s contributed by sharing primary data and technical oversight to harmonize carbon accounting standards across the industry.

This collaboration aims to empower stakeholders to direct investments toward “regenerative agriculture.” These practices focus on reducing chemical dependency, improving on-farm waste management, and enhancing the soil’s ability to sequester carbon rather than release it.

  • A Roadmap for Investors and Farmers

The report concludes with actionable recommendations, stressing that reducing the carbon footprint is no longer just an environmental goal but a commercial necessity. As international environmental regulations tighten, understanding these baselines is essential for maintaining global market access.

The findings confirm that transitioning to integrated nutrient management, improving water efficiency, and recycling coffee by-products into natural fertilizers are the most effective ways to bridge the carbon gap revealed in countries like Colombia and Honduras.

Coffee Carbon Footprint: How Sustainable Is Your Cup?

By: Ennio Cantergiani – Académie du Café

You may have seen claims that coffee emits 2 kg of CO₂e per kilogram, or figures exceeding 28 kg CO₂e per kilogram.
On a per-cup basis, estimates range from around 50 grams to more than 250 grams of CO₂e.

So which number is correct?
All of them — depending on what is being measured.

  • 1) System boundaries: what’s included?

The largest source of variation comes from the life-cycle assessment (LCA) scope used in different studies:

Farm gate only: cultivation and primary processing

Roasted coffee delivered: adds transport, roasting, and packaging

Cup footprint: includes brewing energy and waste

This is why datasets such as Our World in Data report higher coffee emissions than many other foods. They rely on full supply-chain assessments, similar to those developed by Poore and Nemecek, which capture impacts from farm to consumption.

  • 2) Origin dominates the footprint

At the farm level, origin often accounts for 40–80% of total emissions. Key drivers include:

Use of nitrogen fertilizers, which generate nitrous oxide emissions

Land-use change and deforestation

Low yields, which increase land and input intensity per kilogram

Energy use in wet processing and drying

Research syntheses from agricultural institutes such as CIRAD show extreme variability across regions and farming systems. Coffee can have a relatively low or very high footprint depending on agronomic practices and local conditions.

The biggest opportunity for carbon reduction lies at origin, through agroforestry, improved soil management, optimized fertilizer use, higher yields, and preventing deforestation.

  • 3) Brewing method matters more than expected

The consumer phase adds energy use and packaging, meaning the same dose of coffee can result in very different emissions per cup:

Instant coffee (small dose, no machine): ~50–80 g CO₂e

Filter or moka (simple heating): ~80–170 g CO₂e

Espresso machines (electricity and standby losses): ~110–220 g CO₂e

Capsules (packaging and waste): ~120–250 g CO₂e

Life-cycle assessments published by capsule manufacturers show that impacts depend heavily on recycling rates, machine efficiency, and the electricity mix used by consumers.

  • Where can we really save CO₂?

Highest leverage actions:

Origin: deforestation-free + better fertilizer/yield systems

Transport: avoid air freight

Consumer: reduce energy waste (standby), use efficient brewing

Packaging: bulk beans/ground coffee; recycle capsules properly

Same beverage. Different impact.
