Our Mission

CURE100 is a not-for-profit consortium of communities that seeks to reduce global Greenhouse Gas (GHG) emissions to net zero by 2040, or 5% reduction per year, through a combination of advocacy, education and campaigns at the local and global levels. These local and global communities will help each other to take urgent climate action to stave off the worst effects of climate change.

Cure100 Board of Directors

Leo Wiegman, President

Leo Wiegman is Director of Solar Programs at Sustainable Westchester. Previously, he was co-founder of Croton Energy Group, a solar energy firm. Leo is former Mayor of the Village of Croton-on-Hudson, former Executive Director of Sustainable Westchester, and previously worked for three decades in book publishing. Since 2010, Leo has written two books and dozens of articles on sustainability topics and been a frequent speaker on these topics. Leo holds a BS from Tufts University.

In his own words: “Climate disruption is already underway and will further erode how we grow food and find water and avoid disease, let alone how we heat and cool our homes or travel to work or play. Our goal is to help each household know what their contribution toward that disruption is in terms of emissions. We then offer each family a tool they can customize to their lifestyle to plan to reduce their emission year over year with concrete, quantifiable metrics.”
