Pollution Prevention means eliminating or reducing the amount and toxicity of potentially harmful substances at their sources, prior to generation, treatment, off-site recycling or disposal. It emphasizes preventing or minimizing pollution, rather than controlling it once it is generated. Pollution prevention has expanded as new challenges have come into focus - addressing climate change, combating sprawl, and promoting the use of green building techniques and renewable energy. The Department continues to employ prevention as a way to make Connecticut’s environment better and safer as we deal with these challenges.
