Supporting Sustainable Cities | Bloomberg Philanthropies Environment Supporting Sustainable Cities Supporting Sustainable Cities Cities are on the frontlines of today’s most pressing challenges — from pollution and public health to energy access and economic resilience. Home to the majority of the world’s population, cities face the greatest environmental threats, yet they remain powerful engines of innovation and opportunity.

Bloomberg Philanthropies partners with cities and city networks around the world to help equip local leaders and partners with the tools, data, and support needed to reduce pollution, improve quality of life, and deliver economic opportunity through a transition to clean energy and infrastructure solutions. Data: Reliable, accessible data is critical for local leaders to understand pollution’s impact, set targets, and track progress.

Bloomberg Philanthropies helps cities gather and analyze local data to identify challenges and make informed decisions. Solutions: Bloomberg Philanthropies supports cities in developing and applying practical solutions that reduce pollution, improve public health, and strengthen local economies—especially in areas impacted by poor air quality and outdated infrastructure.

These efforts help communities’ lower energy costs, enhance quality of life, and promote long-term economic stability. Partnership & Impact: Bloomberg Philanthropies works closely with local governments, nonprofit organizations, and global city networks to share lessons, scale effective strategies, and build momentum across regions.
