Denmark has announced their plan to achieve carbon-free flights by 2030, joining Sweden with this same ambitious target.
Denmark is yet to develop a concrete plan to achieve the target, with the knowledge that some of the necessary technologies may not yet exist.
Today, the aviation industry is responsible for 2-3% of global greenhouse gas emissions. Denmark now wants to take some initiative with this step, and create momentum to kick-start the financing and development of technologies that enable sustainable air transport. Another company; The Bill Gates Fund, Breakthrough Energy, is also focusing on this area within its strategy.
This commitment hopes to reduce the price of Green Premiums (introduced by Bill Gates), which is the price a customer pays for a more sustainable alternative compared to the price of a conventional product. The goal of Green Premiums should be to determine which technologies are ready to be economically competitive in the marketplace and which still need further R&D, with attention to key technologies for achieving a carbon-free economy in 2050.
For aviation fuel, the gap is one of the highest at 1 gallon/$1.84 for regular fuel and 1 gallon/$9.21 for sustainable fuel, a difference of 400%. For cement, the ratio is: normal cement – $128/tonne and sustainable cement $224/tonne with a final difference of -75%. One of the lowest ratios of Green Premiums is due to the development of renewable sources of electricity, where you get: $0.13 / kWh for normal electricity and $0.15 / kWh for renewable electricity. That is a difference of 15%.
