Stress-test a travel program against rising carbon prices and a changing emissions profile. Compare baseline and future annual carbon exposure, then see how much direct reduction would offset the price increase.
The main result is the change in annual carbon-price exposure under the stress scenario. A positive amount indicates added exposure; a negative amount indicates savings.
This scenario is not a probability forecast. It isolates carbon-price and direct-emissions assumptions and excludes airfare demand, route changes, taxes, and operational costs.
For 120 trips at 0.42 t each, current exposure at $25/t is $1,260. A 20% reduction with a $100/t stress price produces $4,032 of exposure, an increase of $2,772.
It includes only annual travel emissions multiplied by the carbon prices entered.
It is the emissions reduction needed to keep exposure at the baseline level when the stress carbon price applies.
Yes. The result may then show lower exposure, especially when a direct reduction is also entered.
Include any travel modes represented by your emissions-per-trip estimate and keep the boundary consistent.
No. It is a stress-test result based on your selected price, volume, and reduction assumptions.
