There can be toxic levels of lead in all sorts of surprising products, including cosmetics. Lead exposure causes a global health burden comparable to malaria and HIV but receives less than 0.1% of their funding - even though malaria and HIV are themselves neglected diseases. Reducing lead exposure also seems feasible, given the strong historical success of advocacy campaigns. We evaluate Pure Earth’s program to reduce lead in cosmetics in Ghana, involving two years of advocacy and data collection followed by three years of enforcement support for a lead ban. We estimate it delivers 108 WELLBYs per $1,000 donated ($9.23 per WELLBY), making it the most cost-effective charity we have reviewed to-date. Optimistic assumptions increase this as high as 1,359 WELLBYs per $1,000 ($0.74 per WELLBY).
Reducing Lead Exposure
In this report, we provide an overview of all our evaluations to date as well as our conclusions for Giving Season 2023.
In this shallow cause exploration, we explore the impact of lead exposure on subjective wellbeing. We review the literature, model the impact of lead exposure on wellbeing, and conduct some back-of-the-envelope calculations of the cost-effectiveness of various interventions to decrease lead exposure.
