• Investigates the asymmetric effect of several factors on carbon emissions. • This study focuses on Algeria for the period from Q1:1985 to Q4:2022.. • Positive shocks in green technologies and economic policy uncertainty reduce emissions. • Negative shocks in green technologies and economic policy uncertainty are not sufficient to reduce emissions. • The EKC hypothesis is valid.
