The World Bank is facing backlash after reports revealed that its officials collectively emitted carbon equivalent to the yearly emissions of about 350 cars while traveling to a United Nations climate summit in Baku, Azerbaijan, last November.

A leaked list of attendees shows that 254 officials made the trip, resulting in an estimated 1,500 metric tonnes of carbon emissions from their round-trip flights from Washington, DC.

This estimate was derived using the UN's Carbon Emissions Calculator, which gauges greenhouse gas emissions from air travel.

Data from the U.S. Environmental Protection Agency indicates that the reported carbon output is comparable to the annual greenhouse gas emissions from roughly 350 vehicles or the yearly energy consumption of around 200 American households.

In light of the criticism, a spokesperson for the World Bank remarked that the use of private jets is considered an exception, warranted only in cases that require increased security, operational efficiency, or economic factors when commercial flights aren't feasible.

The focus on the organization's travel habits is intensified by earlier reports of extravagant travel arrangements for senior World Bank officials.

Specifically, it was noted that some officials had used Qatar Airways' premium Q Suites for their journeys 18 months prior to the latest summit.

Further scrutiny has been placed on World Bank President Ajay Banga, with social media highlighting his assistant, Jessica Phan, who traveled on a private Gulfstream jet with him.

Phan later removed the images from her Instagram account.

Banga also chartered a Gulfstream jet for his participation in the UN climate conference.

The World Bank is not only under fire for travel costs but also for its climate financing strategies.

In October, the British NGO Oxfam claimed that the organization had 'lost track' of $24 billion designated for climate projects, raising further concerns regarding transparency and accountability.

Additionally, former U.S. Commerce Secretary Wilbur Ross suggested that prominent business leaders, especially those in technological innovation, could help rectify inefficiencies in government spending, potentially referring to the World Bank's management of funds.

In the meantime, Joe Rogers, a former U.S. Ambassador to Italy, criticized the trend of luxury travel within the organization, labeling it as inconsistent with the institution's mission to aid disadvantaged communities.
