OPAL Fuels captures methane from landfills and dairy farms and turns it into renewable natural gas (RNG), and builds fueling stations for trucks. Revenue comes from RNG, power and environmental-credit sales.
What was checked

Pass
Figures from the company's filings (2026-06-30), USD. Market cap is a 36-month average (the S&P Shariah index approach), so a one-day price move does not flip the verdict.
For information (AAOIFI 3/1 note): cash + receivables are 13.0% of total assets (2026-06-30). AAOIFI recommends tangible assets of at least one third — this figure does not affect the verdict, and other major screeners do not apply it either.
