Household consumption increases with the frequency of sports exercise participation,leading to a corresponding in-crease in household consumption carbon emissions.This article aims to explore the mechanisms and micro evidence through which sports exercise participation affects carbon emissions from household consumption,providing theoretical and practical references for achieving household"carbon discharge peak".Using the 2018 China Family Panel Studies(CFPS)individual and household consumption database as sample data,this study employs the Input-Output Model(IOM)to calculate house-hold consumption carbon emissions.Meanwhile,the STIRPAT model,moderating effect,and heterogeneity analysis were em-ployed.The main conclusions are as follows:sports exercise participation has a significant positive predictive effect on house-hold consumption carbon emissions;the increase in consumption carbon emissions is mainly caused by the increased frequen-cy of product consumption brought about by residents'physical exercise behavior,the diversification of sports activities,the specialization and upscale of consumption,consumption imitation behavior,and increased energy consumption.For households with a participation frequency of more than three times a week,public fiscal expenditure and the level of public transportation significantly weaken the positive predictive effect of sports exercise participation on household consumption carbon emissions.Specifically,the weakeningeffect is particularly significant for survival-type consumption carbon emissions.
