1️⃣ Deciding between multiple alternative #aviation fuels is a complex and daunting task, as all options have unique advantages and weaknesses. #RECCE, our new tool, aims to streamline this decision-making process: recce.aiatools.org 
2️⃣ The Resource to Climate Comparison Evaluator (RECCE) allows users to systematically compare 15 aviation fuels across the entire system, from the resources required to produce each fuel to #emissions resulting from infrastructure, manufacturing, on ground operations and flight.
3️⃣ The Resources section displays the cost, #electricity and feedstock required by 2035 to produce enough of each #fuel to fly everyone in the world 1,300km - the average distance flown by each person on Earth in 2019.
4️⃣ The Climate Impact section showcases a detailed breakdown of emissions associated with each fuel, split based on their source: one-off infrastructure, operations on ground and flight. Numbers are given as ranges to account for uncertainties.
5️⃣ #RECCE allows users to visualise the #climateimpact of #contrails, the linear vapour trails formed behind aircraft in-flight. This impact could be very large if the trails develop into clouds, but its magnitude is highly uncertain at the moment.
6️⃣ As #lowcarbon resources are limited in the short term, RECCE can display the emissions that could have been avoided in other sectors if the resources used to produce alternative aviation fuels had been used to help #decarbonise those sectors instead.
