IMPACT, MULTIPLIED CAMPAIGN

Impact, Multiplied is a digital campaign from Climate Mayors celebrating local leadership and how solutions pioneered in one city inspire others and create impact nationwide. By spotlighting innovative, mayor-led initiatives, this social-media-forward campaign shows how local action adds up to national momentum on climate.

Turning Individual Solutions Into Shared Success

Across the country, mayors are delivering climate solutions that make daily life better — cooler neighborhoods, cleaner air, more affordable energy, safer streets, and communities that feel prepared for the future.

And mayors are doing it together. Cities everywhere are looking to one another for inspiration — eager to learn from approaches that work and ready to build on best practices. Impact, Multiplied creates a space where these success stories are easy to find, easy to share, and easy to celebrate.

By elevating local progress through clear, compelling storytelling, the campaign helps mayors amplify what’s working and encourages peers to adapt and expand those solutions. The result is a growing sense of possibility: cities leading with optimism, momentum spreading city by city, and communities nationwide benefiting from proven, people-first climate action.

Boise

Boise’s City of Trees Challenge is rallying the community to plant one tree for every household and one seedling for every resident—growing a greener and healthier city for families to enjoy. With more than 19,000 urban trees and 235,000 forest seedlings already planted, the effort is improving air quality, saving money in energy costs, creating a more beautiful city, and leaving a lasting legacy for future generations. 

Phoenix

Phoenix’s Cool Pavement Program is making neighborhoods more livable by lowering the temperatures on hot summer streets and keeping the heat from lingering at night. With over 140 miles of reflective pavement across the city, the initiative is helping residents stay cooler, protecting public health, and making streets safer and neighborhoods more livable.

Cleveland

Cleveland’s Summer Safety Plan brings the whole city together to make neighborhoods safer, cooler, and stronger. Building on last year’s 13% drop in crime, the city is cleaning up dumping sites, greening vacant lots, repairing streets, and upgrading lighting—simple steps that cut heat, deter violence, and brighten public spaces. By working across departments, Cleveland shows how climate-smart local initiatives can deliver both safer streets and climate-ready neighborhoods. 

Atlanta

WeatheRISE ATL is helping Atlanta families cut energy costs, stay comfortable year-round, and breathe cleaner air through free weatherization and energy upgrades. By focusing on neighborhoods where residents spend a disproportionate amount of money on energy bills, the program is saving families money, reducing pollution, and supporting local green jobs. 

Boston

The Boston Housing Authority is helping seniors and adults with disabilities lower their energy bills with clean, high-quality heating and cooling technology. In partnership with Gradient, the City is installing 100 heat pumps in a 50-year-old public housing community—replacing the building’s currently outdated and inefficient technology. These upgrades will not only bring lower bills—but also help reduce overall energy use, improve indoor and outdoor air quality, and reduce operating costs for building ownership. 

Social Media Content

The Impact, Multiplied campaign features two ongoing social media content series. 

  1. Our City Spotlight Series champions city projects that are already making a difference in the lives of families across the country. 

  2. Our Mayors Elevating Mayors Series gives mayors a platform to shout out their peers who have inspired them. 

Keep an eye on our LinkedIn page to learn more about the mayors who are leading by example with initiatives that deliver cleaner, safer, more accessible, and more affordable cities.
