Fuel and chemistry · £/tCO2-WE Signals
The cost of warming avoided
We are developing a single cost per tonne of warming avoided, so every fuel and policy option can be compared.
The questions it answers
- What does each option cost per tonne of warming avoided, including non-CO2 effects such as contrails?
- What would policy need to pay for a measure to make sense?
- How does the answer change with the metric used?
What you get
- Options ranked by cost per tonne of warming avoided
- Results in tCO2-WE (GWP*, declared 30-year period), with GWP100 and GWP20 alongside
- Uncertainty stated, every time
Delivered in days for a Quick-Screen; complex engagements take weeks.
Who it is for
Policymakers and regulators; airlines; OEMs.
Why you can rely on it
- Built on the GWP* method from the University of Oxford (Allen et al. 2018; Cain et al. 2019) and the reference assessment of aviation's warming (Lee et al. 2021).
- No figures are published until our method has been independently reviewed.
