- Sustainability of the aviation industry, as any other industry, depends on the elasticity of demand for the product and profitability through minimising operating costs. Of paramount importance is assessing and understanding the interdependency and effects of environmentally optimised solutions and emission mitigation policies.This paper describes the development and application of assessment methodologies to better understand the effects of environmental taxation/energy policies aimed at environmental pollution reduction and the future potential economic impact they may have on the adaptation of "greener" novel technologies. These studies are undertaken using a Techno-economic Environmental Risk Assessment approach. The methodology demonstrated allows the assessment of the economic viability of new technologies compared to conventional technologies, for various CO2 emission taxation and fuel price scenarios. It considers relative increases in acquisition price and maintenance costs.A study undertaken as a 'proof of concept' compares a Counter Rotating Open Rotor aircraft with a conventional aircraft for short range operations. It indicates that at current fuel price and with no carbon taxation, a highly fuel efficient technology, such as the one considered, could be rendered economically unviable.The work goes on to demonstrate that in comparison to the conventional aircraft, any economic benefits that may be accrued from improvement in fuel consumption through such a technology, may well be negated through increases in acquisition price and maintenance costs. The work further demonstrates that if policy makers want to direct the industry towards greener propulsion solutions, then an increase in CO2 emission taxation may be appropriate.
