## Questions

### Who runs investment decisions at Environmental Capital Partners?

James A. Attwood Jr., the firm's founder, serves as Managing Partner and leads investment decisions. Attwood launched the firm in 1998 after building an environmental investment practice at Dillon, Read & Co. Earlier in his career, he was an investment banker at CS First Boston. The firm's concentrated partnership structure means Attwood remains closely involved in sourcing, due diligence, and portfolio governance.

### Which sectors does Environmental Capital Partners explicitly avoid?

ECP does not invest in speculative clean-technology ventures, renewable energy development projects, or early-stage environmental software companies. The firm's thesis is rooted in essential, regulation-gated services — solid waste collection, industrial cleaning, hazardous waste handling, and water treatment — rather than capital-intensive energy generation or technology adoption plays where regulatory revenue is not the primary moat.

### How is Environmental Capital Partners funded, and who are its limited partners?

ECP has historically operated with a discrete capital base rather than publicly marketed blind-pool funds. The firm raises capital on a bilateral or co-investment basis from family offices, endowments, and institutional investors comfortable with the environmental services thesis. Because ECP does not maintain a public website or publish fund documentation, the specific LP roster and aggregate committed capital are not publicly available.
