Summary: The text discusses the new speed limits implemented on Dutch highways in an effort to reduce nitrogen emissions. The limits have been reduced to 100 km/h during the day to meet European Union guidelines on nitrogen emissions. This measure is being seen as a potential solution to combat the country's nitrogen pollution crisis, which has led to issues like soil acidification and damage to biodiversity. The government hopes that by lowering the speed limits, they can decrease the amount of nitrogen being released into the atmosphere, thereby improving air quality and the environment overall. However, the decision has faced criticism from some who argue that it will inconvenience commuters and have a limited impact on reducing emissions. Despite these concerns, the Dutch government is committed to enforcing the new speed limits in order to meet environmental regulations and protect public health.
