IIASA, the European Commission’s Joint Research Centre (JRC), and the Population Division of the United Nations Department of Economic and Social Affairs (UNDESA) have joined forces to conduct a survey among world experts in demography to better understand the future of the world population and its impact on various global trends.
Many global trends including economic, environmental, social, and geopolitical changes, depend on the future of the world population. Effectively assessing the future world population is therefore key to better responding to future societal challenges. Current long-term global population projections are based on a variety of methodologies and assumptions employed by leading demography institutions and yield varied results in terms of projected population size and structure – in particular for projections for the second half of the 21st century.
The survey invites experts to express their opinion on the consequences of demographic change for climate change, environmental sustainability, and the economy as well as the role of population policies to address them. It is aimed at the main international associations in population studies and the results will be made available in a dedicated report in September 2023.
“We urgently need to reflect on the ingredients that go into making population projections. We owe this to the users and in particular to the policymakers who will use the projections to inform their decisions. This survey will help us to do just that,” says IIASA Population and Just Societies Program Director, Anne Goujon.

The 2024 State of CDR Report: Scaling up CO2 removal to meet Paris Targets
The 2024 State of Carbon Dioxide Removal report finds that around 7–9 billion tonnes of CO2 per year will need to be removed by mid-century from the atmosphere if the world is to meet the 1.5°C Paris Agreement target. The authors stress that reducing emissions is the primary way to achieve net-zero, but Carbon Dioxide Removal (CDR) has a critical role to play.

Climate change could become the main driver of biodiversity decline by mid-century
Global biodiversity has declined between 2% and 11% during the 20th century due to land-use change alone, according to a large multi-model study published in Science. The projections show that climate change could become the main driver of biodiversity decline by the mid-21st century.
