Act with Passion and Respect

Our commitment to community-led change and improvement stems from our multi-faceted experience in government, commercial and the non-profit sectors.  By fusing our unique knowledge and skill sets with our zeal to improve public health and the environment, we create an innovative platform to attack environmental problems

Environmental Justice for All

Climate Spheres supports and empowers communities as they develop and implement solutions that significantly address environmental and/or public health issues at the local level posed by their disproportionately bearing pollution loadings and exposure.
