What believers are saying

  • Cross-border RNG sales can leverage operating assets in four countries.
  • Existing gas pipelines and CNG delivery expand addressable commercial and transportation markets.
  • JBS USA partnerships validate repeatable on-site RNG development with large industrial hosts.

What critics are saying

  • Feedstock contracts with landfills, farms, and industrial waste owners can be renegotiated quickly.
  • Integrating U.S., French, Norwegian, and Swedish assets creates uptime and management execution risk.
  • European permitting, methane, and transport regulations can delay operating assets and commercialization.

What makes Mobius Renewables unique

  • IFM-backed 2026 launch combined GreenGasUSA and Air Liquide biogas assets.
  • Vertically integrated platform spans development, production, and commercialization across North America and Europe.
  • Portfolio includes over 50 assets and 5.5 million MMBtu annual capacity.
