The Partnership for Policy Integrity, an environmental group based in Pelham, Mass., which focuses on the impact of production and use of bio-fuels, filed a petition with the Securities and Exchange Commission Wednesday asking for guidelines on reporting on the environmental impact of substitutes for fossil fuels.
