Price-induced changes in greenhouse gas emissions from agriculture, forestry, and other land use: a spatial panel econometric analysis

Résumé

This paper provides a quantitative assessment of the effects of input and output prices on French GHG emissions from Agriculture, Forestry and other Land Use (AFOLU) at the Departement level (NUTS2 regions). Four emission categories are considered: (i) N2O emissions from the use of synthetic fertilizers, (ii) CH4 emissions from enteric fermentation, (iii) N2O and CH4 emissions from manure management and spreading and (iv) CO2 emissions from Land Use, Land Use Changes, and Forestry. To assess the impact of crop, livestock, wood, and land prices on each emission category, as well as on aggregated emissions, we estimate a random-effect spatial error model that takes into account spatial autocorrelation in addition to unobserved heterogenity across Departements. Our findings are threefold. First, prices are found to have a significant impact on GHG emissions, although sign and magnitude vary from one emission category to the other. Second, the estimated price effects are more evident when emission categories are analyzed separately rather than aggregated. Third, our results highlight the importance of spatial dimension in the study of GHG emissions from AFOLU. They also suggest that effects of changes in prices should be taken into account in the design of public policies aimed at reducing emissions or enhancing carbon sinks in these sectors.
