Every year, millions of Muslim worshippers visit Mecca in Saudi Arabia to
perform Hajj which is the fifth and last pillar of Islam. In 2018, Mecca hosted
more than 2,300,000 people from around 183 different countries and cultures.
Based on the objective of Vision 2030 of the Saudi Arabian government, the
number of pilgrims was planned to grow to 2.5 million in 2020, and the rate of
increase was projected to be 13% per year. This goal, however, has not been
achieved due to Covid-19. The pandemic forced the government to severely reduce
the number of pilgrims in 2020 to 10,000. Ultimately, this situation will not
last forever and visitor numbers should continue to rise.
Tourism, especially religious tourism such as the Hajj, is expected to boost the
economy and create new jobs for Saudi youth in the services sector. Yet, despite
the many benefits of pilgrimage, the Hajj itself has adverse environmental
impacts. The activities of the Hajj generate considerable solid and liquid
waste, use large quantities of scarce fresh water and produce high levels of
greenhouse gasses (GHGs) emissions. This paper provides an overview of the
environmental impacts created by Hajj 2018 activities and estimates carbon
dioxide equivalent (CO2-e) emissions from municipal solid wastes, travel (air
and land) and electricity generation (accommodation and fresh water
desalination), using a range of estimation techniques based on data collected
across the different Hajj activities. These findings indicate environmental
impacts of the Hajj are significant, highlighting the need for action to improve
environmental sustainability.
