A. ^ In the pilot pageant of Miss Earth in 2001, the title of the 1st Runner-Up was formerly known as Miss Wind, before it was changed to Miss Air the following year.

B. ^ ^ ^ Džejla Glavović of Bosnia and Herzegovina who was crowned as Miss Earth 2002 was dethroned on May 28, 2003 due to the reason cited by the Miss Earth Foundation as "failure to comply with the stipulations in her contract". Winfred Adah Omwakwe from Kenya, then-Miss Air, was formally crowned as the new Miss Earth 2002 on August 7 due to pageant rules stipulating that the 1st Runner-Up/Miss Air will take over if Miss Earth does not fulfill her duties. Prior with this result, each runner-up moved one position so Yugoslavia was the new Miss Air, Greece is Miss Water and Elina Hurve of Finland is the new Miss Fire. Hurve is a semi-finalist in the said competition. This year also marked the dethronement of another beauty queen Oxana Fedorova of Russia (her fellow European), who was originally Miss Universe 2002 (she was replaced by Justine Pasek of Panama who is the 1st Runner-Up).
C. ^ Yanina Gonzalez, then-Miss Fire 2004, competed at Miss Universe 2004 and eventually placed 3rd Runner-Up in the said competition, marking her as the first Paraguayan woman to obtain the highest position ever slated to a Miss Paraguay, obtain same placements at separate pageants, marking at the Top 5 respectively and the first Miss Earth titleholder to do so.
D. ^ ^ Jennifer Pazmiño of Ecuador, then-Miss Air 2010 was dethroned due to her upcoming marriage with her fiancee in February 2011. Therefore, Carousel Productions decided that the new Miss Air 2010 would be Viktoria Shchukina from Russia, who was originally placed as a semi-finalist in the pageant (For the first time, a semi-finalist was appointed to become the 1st Runner-Up in a particular pageant should the original winner would relinquish her position, other than a finalist.) Unlike the 2002 dethronement, there was no movement of one position higher so those under Miss Air (Miss Water and so on) stayed the same.
E. ^ Punika Kulsoontornrut of Thailand, then-Miss Water 2013 was dethroned due to her violations in her contract as titleholder last October 13, 2014, with regards to her participation in Miss International 2014 last November 11. She eventually placed 2nd Runner-Up in the competition (the same placement she held last year), making her the second to have the same placement in separate pageants, after Yanina Gonzalez of Paraguay did.
F. ^ Maira Alexandra Rodriguez, Miss Water 2014, from Venezuela wasn't actually the original delegate of her home country to Miss Earth 2014. It was originally Stephanie de Zorzi who would represent Venezuela, but later withdrew by pageant organizers due to weight issues. Rodriguez was originally the Venezuelan delegate who would compete at Miss Earth 2015 which was held at Vienna, Austria on December. De Zorzi competed in the 2016 edition obtaining the 2nd runner up (Miss Earth Water) position.
G. ^ Corrin Stellakis, Miss Earth United States 2016, was declared as the new Miss Earth Fire 2016 on March 8, 2017. If Brazil didn't resigned, they would have completed their reigns by becoming the first country to score back-to-back Miss Earth-Fire titles.
H. ^ This edition marked a number of firsts. Apart from Vietnam's first win in Miss Earth, Melanie Mader made history by being the first candidate to compete in both the origin regional pageant Miss Philippines Earth and Miss Earth itself. She managed to become Miss Philippines Eco-Tourism (then Miss Philippines Water afterwards) 2016 prior to her win as Miss Earth-Air 2018. Colombia became the first country to score back-to-back wins as Miss Earth-Water.

I.^ India became the first country to score back-to-back wins as Miss Earth-Air.
