This paper proposes a new method for evaluating green growth in agriculture (GGA) based on a set of key performance indicators and a synthetic index. To this end, we used the zero unitarisation method. The objects of study were seven countries/groups of countries with the largest share in agricultural production in 2020. This paper attempts to answer the following questions: (1) Has there been any progress in fulfilling the assumptions of the green growth concept implemented in the agricultural sector of the examined countries? (2) Which countries do better, and which do worse in that respect? (3) What are the challenges respective countries need to face? In the analysed years, the mean GGA index increased from 0.3287 to 0.3342, which means that the overall level of ‘greening’ in agriculture grew insignificantly. Out of the seven analysed countries/regions, China did the best in handling the challenges of GGA, while India did the worst. The paper discusses the reasons for this state of affairs, simultaneously making recommendations for improving the existing situation.
