After the Conference voiced its concern for legal loopholes to the state legislature in Harrisburg, Pennsylvania, a comprehensive anti-pollution law was passed in 1949 for Allegheny County.
The clearer skies over the city both attracted new business and encouraged local corporations to retain and expand their Pittsburgh headquarters.
The pollution-control program explicitly influenced the decision of the Equitable Life Assurance Society to invest in planning the Gateway Center project, a keystone of economic revitalization in Downtown Pittsburgh during Renaissance I.
The Conference also played a role in the appropriation of funds for the construction of flood control dams on the Allegheny and Monongahela rivers.
A related effort was Strategy 21 that enabled public and private agencies in Allegheny County to speak with one voice when requesting state funds.
