The emission of nitrogen oxides in Flanders decreased by 35% between 2015 and 2022, while ammonia emissions fell by 9%, according to the Progress Report on the Nitrogen Programme Approach presented by Environment Minister Jo Brouns to the Flemish government on Friday.
Between 2015 and 2022, total nitrogen deposition on nitrogen-sensitive habitats within special protection zones dropped by an average of 21%. Nitrogen oxides primarily come from the transportation, energy, and industry sectors, whereas ammonia mainly originates from the agricultural sector.
Brouns attributes the reduction in ammonia emissions largely to a decrease in farm emissions, with improved barn systems and a smaller pig population being the main factors. The decline in nitrogen oxide emissions is closely linked to the greening of the vehicle fleet.
The effects of the nitrogen decree are not yet visible in the figures, as it only came into effect in 2024. The decree aims to reduce ammonia emissions in Flanders by 40% by the end of 2030 and nitrogen oxide emissions by 45%.
“The figures show a significant decrease in nitrogen emissions, and now it’s crucial to build on this trend to achieve our reduction targets,” Brouns said. “Everyone is making incredible efforts. For me, it’s important that in exchange for these substantial efforts, there is also perspective for the involved entrepreneurs.”
He reiterated the intention to shift from a deposition model to an emission model.
