Under the Paris Agreement, nations made pledges known as nationally determined contributions (NDCs): national climate plans detailing countries' ambitions to adapt to climate change and reduce greenhouse gas emissions. Population growth is a driver of both climate vulnerability and climate-altering emissions. We asked, to what extent do countries take population growth into account in their NDCs, beyond simple statements of population trends? Our research method was a comprehensive text review of 164 NDCs submitted by countries. About one-third (49) of countries' NDCs either link population growth to a negative effect and/or identify population growth as a challenge or trend affecting societal needs. Common impacts of population growth noted were increased energy demand, natural resource degradation, vulnerability to climate impacts, and decreased food and water security. Seven NDCs included strategies to slow population growth, and none specified implementation measures. Overall, the adaptation potential and mitigation co-benefits associated with slowing population growth through meeting the unmet need for family planning are largely overlooked in national NDC documents, suggesting that they are also neglected in countries' climate change planning. In upcoming rounds of NDC updates, we recommend that governments consider the potential impact of population growth on adaptation and mitigation efforts, prioritize meeting their unmet needs for family planning, and integrate population-health-environment projects in their national climate plans.
