It comes after the industry body launched a net-zero roadmap to support the global travel and tourism sector in reaching the milestone by 2050.
It said the roadmap presents a new target framework with decarbonisation corridors, which groups businesses into three clusters, depending on their emission profiles and the difficulty of abating their GHG emissions.
The report includes decarbonisation levers and corresponding actions for five areas of the sector: accommodation, tour operators, aviation, cruise, and tourism intermediaries such as online travel agents (OTAs) and metasearch engines.
Acknowledging that different industries face different challenges to decarbonise, the WTTC called on businesses to "increase their ambitions where possible".
The roadmap will set baselines and emission targets now to achieve individual and sector goals, monitor and report progress regularly, collaborate within and across industries and government, provide finance and investment required for the transition and raise awareness and build knowledge and capabilities on climate change.
The roadmap will also give recommendations to governments on how they can support the sector to address climate challenges and reach goals to achieve net-zero.
The WTTC developed the plan in collaboration with the UN Environment Programme (UNEP), the UN Framework Convention on Climate Change (UNFCCC), and Accenture.
Julia Simpson, WTTC president and chief, said the roadmap will help travel businesses reach individual targets to reduce the sector’s carbon footprint.
"Many destinations are affected by the impacts of climate change with rising sea levels, deforestation and the loss of animal and plant species," she added.
"Communities that rely on tourism are first in line to see the impact and wanting to do something about it.
"The travel and tourism sector is taking this opportunity to be a catalyst for change. We have a responsibility towards our people and planet."
