The key findings highlighted the importance of biodiversity in coffee production as a response to climate change, the significant health benefits and sustainability potential of coffee by-products, and the evolving landscape of coffee consumption patterns driven by technological innovations. The convention also stressed the need for alignment in global coffee trade regulations, particularly concerning deforestation and traceability. The 2023 convention underscored the complexity and interconnectivity of the coffee industry’s challenges and opportunities. It concluded with a forward-looking perspective, emphasizing the need for continued research, sustainable practices, and collaborative efforts to shape the future of the coffee industry. The community is looking forward to furthering these discussions at the next International Coffee Convention in 2024.

The coffee sector is facing a number of challenges in 2024, including the implementation of the new European Union (EU) deforestation regulation, the proposed reclassification of dichloromethane, the significant increase in the price of green coffee, and the effects of the EU corporate sustainability due diligence directive. These factors have the potential to result in a shortage of products on the market, which could have a significant impact on consumer prices.

Dichloromethane (DCM) is extensively used around the globe in various applications, such as in closed industrial installations for food processing or pharmaceutical extractions (vitamins, antibiotics, etc.). In the coffee sector, it is used as an extraction agent for the decaffeination process of green coffee beans. Due to its low boiling point, ranging at approx. 40 °C, DCM can be easily removed subsequent to caffeine extraction by applying state-of-the-art solvent stripping processes. The intention of this study is to assess how much DCM, if any, is present in decaffeinated coffee packages as sold to the consumer, as well as how much of the extraction solvent residue is transferred into the finally prepared, consumable coffee beverage. This study sets out to highlight DCM contents of decaf coffees, directly taken from six EU countries’ supermarket shelves. In addition, DCM mass transfer rates from roasted coffee matrices into the corresponding, variously prepared beverages (drip percolated coffee, French press) are determined. All analyses were performed applying a Headspace-GC-MS technique. All presented data demonstrate that DCM residues in the 34 coffee samples analysed have contents well below the DCM maximum residue limits for roasted coffee both in the European Union (2 mg/kg) and the USA (10 mg/kg), with an average of 0.127 mg/kg, median value of 0.059 mg/kg and P95 of 0.444 mg/kg. Furthermore, this study shows that DCM mass transfer rates from the coffee matrices into the corresponding beverages have, for drip coffee, an average of 24.7% and median of 26.8%, and for French press, an average mass transfer of 41.9% and median of 43.1%.

In a forcedly global system, we are facing a more and more regulated, sustainable coffee market. The International Coffee Organization is the only coffee intergovernmental organization working to face the numerous challenges of this polyhedric world, from producing fields to consuming markets. Coffee statistics, a unique table for discussion, starting from multilateral up to bilateral dialogue, involving private entities and civil society, cooperation and development projects, and the circular economy are some of the main issues for this intense year 2023. In Europe, one of the main issues for coffee contaminants is the renewal of the authorization as an active substance for glyphosate, which is a chemical widely used in herbicide products, especially in the coffee sector. The use of glyphosate is approved in the EU until 15 December 2023, subject to each product being authorized by national authorities following a safety evaluation. In July 2023, EFSA published the results of a risk assessment for the active substance glyphosate, where no critical areas of concern for the health of humans, animals, or the environment have been identified. Due Diligence: On 1 June 2023, the European Parliament agreed on its position on the Directive on Corporate Sustainability Due Diligence (CSDDD), which requires in-scope companies to conduct due diligence on and take responsibility for human rights abuses and environmental harm throughout their global value chains. The European Coffee Federation has supported the proposal in May 2022 through a position paper, as it is an important step toward the development and promotion of more socially and environmentally sustainable and responsible coffee value chains, sustainable sourcing approaches, and the prevention of loss of biodiversity and natural resources. Deforestation EU regulation: changes to food systems are required to halt deforestation and forest degradation to slow the rate of climate change and the threat to global diversity. Henceforth, the EU deforestation regulation aims to minimize the risk of placing products and commodities on the EU market that cause deforestation and forest degradation. There is a strong need to conduct country-level assessments on the readiness to fulfill the new EU legislation, especially on how smallholder coffee farming families would be affected. To be prepared, producing countries, coffee farmers (and particularly small-holder farmers) and their producer organizations need timely information on guidelines and capacity building on regulatory due diligence. Data requirements on geo-localization and traceability need to feed a discussion on how data should be managed and by whom, as well as on data ownership. Sector-specific guidelines are required, and for the coffee sector specifically, on how to differentiate between forest and coffee agroforestry systems such that coffee farm management is not seen as deforestation. As evident, more and more issues for a sustainable coffee world are arising, impacting the whole global coffee market; traceability is becoming a pillar on which it needs to be developed, stimulating multilateral and bilateral dialogue to help all countries align their capacities to reach this important common target.

Nowadays, traceability is the main issue in many businesses, particularly for coffee. The advantages of keeping it at a high degree are that it provides a guarantee for consumers, provides increased power in the value chain, helps quality monitoring, and, last but not least, can be used a marketing tool. In the coffee business, it means verifying the history and the area of origin of green coffee beans (now moving to geolocation) and being able to identify them throughout all the logistic supply chain up to the last customer; to help this, we conceived an innovative service model of traceability and integration through a technique that recognizes the connection between genetic characteristics of coffee varieties and chemical and sensory analysis results, shared on a dedicated platform and linked to a QR code. By linking shipping documents with the results of chemical, genetic, and sensory analysis, users can verify the compliance of all declared data with the quality of the product received. Genetic analysis is based on DNA fingerprinting, detecting the presence of short and repetitive sequences (microsatellites) and characteristics of beans’ genetic code; thanks to a rich Coffea Arabica library that was built, DNA analysis identifies different varieties of green coffee beans which are also linked to the production countries. Chemical–physical analyses consist precisely of the determination of moisture, caffeine, 5-hydroxytrypdamides, and OTA, and sensory analyses are performed through the SCA cupping protocol. Gathered using a blockchain system, all the documents are available in sample cards to guarantee the transparency to both buyer and seller, from bean to cup.

The International Coffee Convention 2024 (ICC2024) continued the discussions initiated at ICC2023, focusing on coffee's transition and the industry's challenges. The event, held in October in Mannheim, started with a welcome speech from Vanúsia Nogueira, the Executive Director of the International Coffee Organization (ICO), and brought together leading industry figures, experts, and stakeholders. The convention examined multiple aspects of the coffee sector, including the future landscape of coffee species, particularly the potential of _Coffea canephora_ and other species such as _C. racemosa_ and _C. stenophylla_. A key highlight was an exclusive satellite workshop, organized in partnership with the Global Crop Diversity Trust, the Coffee Consulate, RD2Vision, and supported by the ICO, which addressed the use of coffee genetic resources within the framework of the Nagoya Protocol. Coffee production's environmental footprint emerged as a central theme of the conference, with discussions covering deforestation policies, fermentation techniques, and processing methods. The sessions explored innovations in coffee preparation and business, from roasting techniques to crafting the perfect Café Crème. The program included analyses of coffee's nutritional impacts, health benefits and risks, and the evidence supporting health claims. The sustainable use of coffee by-products was also featured, stressing both challenges and opportunities. ICC2024 gathered international experts who shared scientific knowledge and practical insights. The convention ended with the presentation of the Kaldi Award, recognizing significant contributions to the coffee industry. Through this comprehensive program, ICC2024 contributed to shaping coffee's future by facilitating truly interdisciplinary knowledge exchange and addressing key industry challenges and opportunities.
