For most of Elizabeth Sawin's career, she was not a multisolver. Instead, she worked on a single, albeit immensely important problem: climate change. Despite tremendous effort, she felt like she was chasing her tail. Unless people began to recognize the multitude of unexpected benefits from ratcheting down emissions, climate change would remain a losing political issue.

That experience, along with the guidance of leaders in systems thinking and racial justice, convinced her that the world's thorniest problems may be easier to tackle together than one by one. That's multisolving: using a single investment of time or money to solve many problems at the same time. Multisolving addresses the current mismatch between complex, deeply intertwined societal issues and our siloed approach to them.

This unique resource is for local school boards that need revenue for their students but don't want to overtax low-income seniors. It is for nonprofits working to reduce food waste and combat the root causes of hunger while increasing racial justice.

It may also be for you: doing the work you know is imperative but that is sometimes overwhelming, a tiny drop in a swirling ocean.
