Frequently Asked Questions

How can flights be considered sustainable when aviation is a high-emission sector?

They can't. Flying is among the highest emission activities we can undertake as human beings. And yet flying is an important part of international business. We have climate scientists using RouteZero to consider the impact of attending a particular event or conference, in person. Each journey is unique and needs to be assessed carefully for impact.

Aviation remains carbon-intensive, with very limited options for near-term decarbonisation (particularly regarding alternative fuels and their industrialisation) (and not before 2050, the IPCC's Net Zero deadline). Bain & Company's research shows "there is no clear solution for decarbonising the bulk of commercial aviation by 2050, even assuming major technology advances and cost reduction".

RouteZero focuses on relative emissions reduction through optimisation, not absolutes. This includes booking direct flights to lower fuel burn per kilometre, selecting airlines with newer, advanced aerodynamics and more efficient fleets (e.g. A320neo, 787), and avoiding premium cabin seating that disproportionately increases emissions per traveller. Full elimination of impact is not possible (although a measure of journey avoidance is achieved by eliminating wasteful or non-strategic trips); sustainability is pursued through minimisation and mitigation.

Do you offer tools to compare the emissions of different flights or carriers?

Yes. RouteZero provides flight-by-flight emissions data based on aircraft type, route distance, load factors, and operational efficiency where available. Matching these data to the tail number of specific aircraft determines efficiency and fuel performance by route, by seat. Results highlight emissions per passenger per kilometre, benchmarked against route averages. However, data granularity has some limitations (we currently cover 99.5% of scheduled passenger flights globally for detailed, per seat emissions data) and is evolving quickly (e.g. contrail impact and contrail avoidance opportunities).

Can we offset the emissions from air travel through your platform, and how credible are those offsets?

Offsetting is not available. Offsetting does not address immediate emissions and should not be treated as equivalent to reduction. Scientific scrutiny continues to question the permanence and additionality of many schemes. A University of Cambridge-led study found that, among 18 major forest carbon offset projects examined, 94% had no measurable impact on actual emissions reductions. In alignment with the Science Based Targets Net Zero Standard, RouteZero focusses on reducing customer greenhouse gas emissions by at least 90% by 2050. Carbon offsets cannot be used as a reduction mechanism. They should be applied to residual emissions only.

What other measures can we implement to reduce the environmental impact of necessary flights?

RouteZero targets users to shift short-haul flights to rail where the duration, cost and emissions reduction trifecta permits. Internal carbon pricing can be applied to high-emission routes to influence choice behaviour. Company-wide reporting includes per-seat emissions trend analysis, modal substitution rates, and compliance with defined low-carbon travel policies.
