Market Report | February 2023

“CP21 pricing has slowly declined over the past few weeks; now might be a good time to lock in remaining volumes.”

“The Crop RGGO prices gains continue at an unprecedented rate.”

Mike Ridler


  • Prices continue to rise with a strong demand for Crop certificates
  • Crop prices are now closing in on Waste, begging the question of how high can Crop go?
  • The General Court of the European Union decided to annul Sweden’s exemption from energy and carbon taxes for non-crop-based biogas.
  •  Non-ISCC Waste prices have stalled as waste certificate supply in Europe increases due to decreased demand, as Swedish buyers hold off awaiting an appeal of the ruling.
  • ISCC Waste Certs are still commanding high price levels, especially when they can be coupled to gas from the AD plant.
  • There has been an increase in interest by plants looking to gain ISCC and DENA accreditation to increase certificate values further.

“RTFCs Continue to feel pressure from low biodiesel prices.”
