12 Carbon-Free Journeys That Will Define the Future of Sustainable Tourism

2. Electric and Hybrid Short-Haul Aircraft

Electric and hybrid aircraft are emerging as realistic options for regional routes under roughly 500–1,000 kilometers, where battery energy density and range constraints are less limiting than on long-haul flights. Developers are focusing first on commuter and regional aircraft that can replace short-haul flights with near-zero tailpipe emissions. Batteries and hybrid systems still add weight, which affects payload and route economics, so the earliest adopters will likely be short island hops and compact regional networks. For passengers, the result could be quieter, cleaner flights that shave a trip’s carbon footprint substantially compared with conventional engines. Policymakers and airports are preparing charging and ground infrastructure, and airports serving short routes will be the first where electric aircraft become routine. When planning regional travel, look for airlines piloting electric or hybrid services and consider rail or ferry alternatives on routes where those options exist — they may already offer lower in-route emissions and more relaxed boarding processes.
