•  India – Nishi Bharadwaj has been appointed as Miss Earth India 2018 by Glamanand Supermodel India Organization as a replacement to the original title holder of Miss Earth India 2018 Devika Vaid. The original winner suffered with an injury making her unable to compete at the forthcoming Miss Earth 2018.

•  South Africa – Margo Fargo was appointed as Miss Earth South Africa 2018. The appointment was due to conflict of schedules with Miss Earth South Africa 2018 pageant and the Miss Earth 2018 pageant arrival. Fargo previously worked as Miss Earth South Africa Ambassador in 2014 and recently competed for Miss South Africa 2018, where she placed in the Top 12.
•  Thailand – Nirada Chetsadapriyakun was appointed as Miss Earth Thailand 2018 by Pawina Bumrungrot, National Director of ERM Marketing Co., Ltd., Thailand. Nirada was the 2nd Runner-up of Miss All Nations Thailand 2017.

During the contest

•  Canada – Jaime Vandenberg participated in some the preliminary activities in Manila but she decided to withdraw before the coronation night after accusing one of the Filipino food sponsors of sexual harassment during a dinner at the Manila Yacht Club.
•  Lebanon – Salwa Akar was dethroned the title "Miss Earth Lebanon 2018" by the Miss Lebanon Organization after her photo with Miss Israel appeared in the media. She returned to her hometown afterwards.

Before the contest

Miss Lebanon 2018 Salwa Akar received international press attention when she was stripped of her title in Lebanon, while participating in Miss Earth 2018 pageant after she posted a photo in Facebook with her arm around Miss Israel's Dana Zreik and making peace signs. Lebanon and Israel are in a long-standing state of war. As a result, she was unable to continue her participation in the Miss Earth pageant. In a press release, Israel's Prime Minister Benjamin Netanyahu’s spokesman Ofir Gendelman reacted on Akar’s dethronement and condemned the "Lebanese apartheid."

On November 7–8, 2018, Jaime Vandenberg of Canada, Abbey-Anne Gyles-Brown of England, and Emma Sheedy of Guam accused one of the Filipino food sponsors of sexual harassment during a dinner at the Manila Yacht Club, claiming that he asked them for sexual favors in exchange for the crown or an advancement in the pageant. Sheedy had identified the sponsor as Amado S. Cruz, who is president of a car rental company and CEO of a construction company. The Manila Yacht Club officials clarified that Cruz is not a member and could have just been sponsored by another member. The pageant officials indicated that Cruz was not one of the major sponsors of the pageant and just sponsored for an evening meal.

Vandenberg withdrew from competition after Cruz obtained her mobile number without her consent and kept calling her for her hotel and room number. The pageant officials stated that they did not know how Cruz obtained her number, and they only have the delegates' international contact numbers and the pageant's mode of communication was through messenger and group chat only.

Vandenberg also claimed the organizers confiscated her passport on the first day of competition. The pageant organizers denied Vandenberg's claim, stating that delegates are free to keep their passports by signing a waiver and they only keep the passports for safekeeping since there had been many occasions of misplacing or losing their passports and to facilitate check-in for their domestic flights and hotel accommodations.

Vandenberg also said that seven candidates left the dinner and accompanied by the team managers to sit on the bus after feeling uncomfortable with the sponsor. All three candidates voiced their complaints to organizer Lorraine Schuck, but despite Schuck's assurance that Cruz would not be allowed near the candidates, he still appeared in the pageant. Schuck then stated that she does not have any authority in public places, such as the hotels where the delegates stayed and the Mall of Asia Arena where the grand final of the pageant took place since the pageant was a public event. Furthermore, Schuck said that all the delegates had police escorts for their safety. Schuck subsequently announced that Cruz is 'forever banned' from Miss Earth.

On November 9, 2018, Cruz denied the accusations of the three candidates. In addition, Monica Aguilar of Cuba claimed there were no instances of sexual harassment during the competition. Instead, she stated that the sponsor asked only if they wished to extend their visas to proceed to Boracay after the pageant, and she further stated that "no one was promised to get us further in the competition through 'sexual favors."

On November 10, 2018, Schuck's company Carousel Productions Inc. urged other candidates to come forward if they experienced any incidents of sexual harassment during the pageant. The organizer also expressed support to the delegates in case they decide to take any further action to the alleged perpetrator.
