Parnassus Investments

Trucost was commissioned to perform regular carbon intensity measurement of Parnassus Investments’ portfolios.

Parnassus Investments is an independent and employee-owned investment management company based in San Francisco, California. The firm seeks to invest in good businesses that have increasingly relevant products or services, sustainable competitive advantages, quality management teams and ethical business practices.

“Recognizing the increasing urgency to react to climate change, we have been considering what more we can do as investors. We have participated in the Sustainability Accounting Standards Board (SASB) initiative to develop standards for sustainability reporting for relevant industries. We have also encouraged sustainability disclosure at multiple portfolio companies and voted related proxies. At our investment team’s summer offsite meeting, we formalized our procedures relating to carbon emissions, adding a high-level committee’s oversight across the Parnassus Funds. We also elected to have Trucost, an independent research provider, regularly measure carbon intensity in our portfolios.”
