The objective of this contribution is to analyze the existing relation-ships between agriculture, economic growth and greenhouse gas emissions in Algeria during the period 2000-2022. A Principal Component Analysis (PCA) was applied to the study data in order to assess the possible positive role of agriculture (as a brake on climate change) in reducing CO2 emissions. The results indicated that both agricultural land and forest area contributed more to the increase in CO2 than to its reduction. The Granger causality test was adopted to test the causal relationships between agricultural production and economic growth, and between agricultural production and greenhouse gas emissions (all gases combined). The results revealed the existence of a unidirectional relationship between agricultural production and greenhouse gas emissions, and the absence of a bidirectional relationship between agricultural production and economic growth. Algeria should develop sustain-able agricultural policies that reconcile economic growth with the reduction of greenhouse gas emissions.
