The Philippine dairy business, worth Php100 billion, has a far way toward meeting the country's dairy demands. Local dairy farmers fulfill 1% of the need, despite yearly imports of $800 million in dairy goods. Dairy is the third most imported agricultural item, with 85 percent of the country importing it in powder form, which is subsequently processed into a liquid for household usage. Milk manufacturing has a number of environmental consequences. Dairy cows and their dung create greenhouse gases including methane, nitrous oxide, and carbon dioxide, which contribute to climate change. The study assessed the technical and economic efficiency of green dairy technology utilization in the Cagayan Valley. Specifically, it analyzed the determinants that affect dairy farmers' technical and economic efficiency by utilizing green technologies. It gathered data and information via a semi-structured questionnaire. The data were processed using descriptive statistics and stochastic frontier analysis. The majority of the 11 dairy farmers surveyed were male, older farmers, with greater household size, who obtained their 9 years of school and had a lower monthly income of Php13,863.91. The productivity model reveals that the material costs that contributed to increasing milk productivity are significant. The lower cost of materials was due to the adoption of green technologies like silage making, vermiculture/composting, and recycling of farm wastes. The number of dairy animals, pre/post-harvest labor costs, and investment were all negative coefficients that did not affect milk productivity. Furthermore, age, household size, and agricultural years were among the technical inefficiencies that had a substantial impact. Dairy producers' technical inefficiency is aggravated by their age and years of farming. These farmers are getting older, starting at an age of 55.54, deteriorating their technical efficiency performance attributed to physical strength to perform dairying activities, while years of farming experience of 23.32 and above dairy farmers are attributed to their resistance to adopting green technologies. A household with four or fewer family members has fewer technical inefficiencies. The number of workers is usually drawn from the family members that contribute to better technical efficiency performance.
