The Impact of Net Zero Strategies on the Tourism Sector

Tourism produces a large share of the world's greenhouse gases. Aircraft flights, hotels, and cruise ships release most of those gases. A review of every relevant study published between 2015 and 2024 shows how tourism plans to reach net zero emissions, plus what happens when such plans are put in place. The main actions are set targets that follow climate science - install more efficient engines, boilers, and air conditioning - replace fossil fuels with solar, wind, but also other renewable sources, protect and restore forests, wetlands, as well as reefs that absorb carbon; and let Destination Management Organizations lead the way with clear long-term strategies. Success depends on new hardware but also on firm rules, budgets that reward low-carbon choices, or cooperation among governments, businesses, and residents. Local laws next to national laws determine how quickly a place cuts carbon, and if visitors still regard it as attractive. The survey confirms that companies, public agencies plus travelers must act together - one group alone cannot push emissions to zero. More work is needed to track results over many years and to compare airlines, hotels, cruise lines, and also individual resorts in different parts of the world.
