Giảm phát thải CO₂ trong chuỗi giá trị cà phê hướng tới nông nghiệp bền vững

Abstract

The study assessed the amount of greenhouse gas emissions (CO₂) across the entire coffee value chain in Lam Dong province from cultivation, harvesting, and processing to consumption applying the 2006 IPCC Guidelines. The results showed that CO₂ emissions from the coffee chain are 14,300 kg CO₂ha^-1year^-1, mainly originating from chemical fertilizers (42%), fossil fuels (36%), and electricity (22%). Concurrently, organic coffee cultivation also demonstrated significant CO₂ absorption capacity, averaging 17,249 kg CO₂ha^-1year^-1. Proposed solutions included using organic fertilizers, biochar from coffee husks, water-saving irrigation systems, renewable energy, and digital technology. The combination of technical, technological, and policy solutions can significantly reduced CO₂ emissions, contributing to sustainable coffee development.
