Previous research demonstrates that low-income countries face higher risks than high-income countries from toxic pollution and climate change. However, the relationship between these two risks is little explored or tested, and efforts to address the risks are often independent and uncoordinated. We argue that the global risks from toxic pollution and climate change are highly correlated and should be jointly analyzed in order to inform and better target efforts to reduce or mitigate both risks. We provide such analysis for 176 countries and found a strong (rs = -0.798;95%CI -0.852, -0.727) and significant (p<0.0001) relationship between the distribution of climate risk and toxic pollution. We also found that inequities in pollution production, economic status, and institutional readiness are interconnected and exacerbate risk for countries already in the highest risk categories for both toxic and non-toxic (greenhouse gas) pollution. The findings have policy implications, including the use of the proposed Target assessment to decide where best to address toxic and non-toxic pollution simultaneously, based on the need to minimize human suffering and maximize return on effort.
先前的研究表明,与高收入国家相比,低收入国家面临更高的有毒污染和气候变化风险。然而,这两种风险之间的关系很少被探讨或检验,解决这些风险的努力往往是独立的、不协调的。我们认为,有毒污染和气候变化的全球风险高度相关,应进行联合分析,以便为减少或缓解这两种风险提供信息并更好地确定工作重点。我们为 176 个国家提供了这种分析,发现气候风险分布与有毒污染之间存在很强的(rs = -0.798;95%CI -0.852,-0.727)和显著的(p<0.0001)关系。我们还发现,污染产生、经济地位和机构准备方面的不平等是相互关联的,加剧了那些已经处于有毒(温室气体)污染和非有毒污染的最高风险类别的国家的风险。这些发现具有政策意义,包括根据减轻人类痛苦和最大限度提高努力回报的需要,使用拟议的目标评估来决定在何处同时解决有毒和非有毒污染的问题。
