摘要

Nitrogen waste poses substantial threats to global sustainable development through multiple pathways, prompting the United Nations to propose halving nitrogen waste as a means to achieve Sustainable Development Goals (SDGs). However, the pathways and potential to improve global SDGs through halving nitrogen waste are less well known. Here we use an integrated assessment framework to quantify the cost-effectiveness and environmental impacts of halving nitrogen waste. We show that nitrogen waste is directly and indirectly linked to all 17 United Nations’ 2030 SDGs and that halving nitrogen waste could enhance global SDG performance by 19%. The total societal benefit of halving nitrogen waste could be as high as US$1,379 billion, considering improvements in human and ecosystem health and mitigation of climate change. Whereas implementing control strategies aimed at halving nitrogen waste may cost up to US$1,137 billion, adopting more cost-effective strategies could decrease costs by up to 72%. Our findings provide crucial insights for policymakers and underscore the urgency of developing cost-effective nitrogen-waste-reduction strategies to achieve global sustainable development.
