Bill Gates has called for a reassessment of global climate policy priorities ahead of the COP30 climate summit, arguing that an excessive focus on near-term emissions reduction targets risks diverting resources from interventions that would more directly improve living conditions in low-income countries.
The remarks appear in a 17-page memorandum released on Tuesday, coinciding with Gates’s 70th birthday, where the Microsoft co-founder characterises parts of the global climate narrative as “overly alarmist.”
While acknowledging that climate change will impose “serious consequences,” particularly for vulnerable populations, he argues it will not threaten humanity’s survival and should be addressed alongside the broader drivers of human suffering.
Development as a Pathway to Climate Resilience
Gates highlights the persistent burden of poverty-related diseases, such as malaria, tuberculosis, HIV/AIDS and respiratory infections, which collectively cause around 8 million deaths annually, compared with an estimated 500,000 deaths from extreme heat.
He argues that economic development and improved health outcomes can substantially reduce climate vulnerability, citing research from the University of Chicago’s Climate Impact Lab showing that projected climate-related mortality drops by more than half when expected economic growth in low-income regions is factored in.
Asked whether he would accept a marginally higher global temperature to eliminate malaria, Gates responded that a 0.1°C rise would be a trade-off he would accept if it delivered that outcome.

The memo marks an evolution in Gates’s messaging. While he remains a prominent investor in climate technology through Breakthrough Energy, he argues that climate finance should be allocated proportionally to measurable human welfare benefits rather than exclusively toward temperature-based targets.
The intervention comes as global development budgets face renewed pressure. Recent reductions in international aid, including the closure of USAID under the Trump administration, have raised concerns about funding gaps for health and food security programmes.
Gates’s memo questions whether current climate spending patterns optimally support vulnerable populations and urges COP30 delegates to examine whether funds could achieve greater impact by integrating emissions reduction with poverty alleviation and health systems strengthening.
