Since its creation in 1960 and throughout its 56 years of existence, CABEI has reaffirmed its commitment to play an active and leading role in adapting and mitigating the effects of climate change in the region, financing projects that contribute to solve this problem, most of which belong to the sectors of road infrastructure, health, water and sanitation, and agriculture.

On July 29, 2016, the Bank made its first green bond placement in the Uridashi market in Japan, in South African Rands (ZAR) for an amount of ZAR 1,032 million (equivalent to US $ 72.9 million).

Through this issuance, CABEI became the first Central American issuer to place this type of bonds. Green bonds represent a new funding source to reach investors committed to environmental sustainability and who identify with the Bank's commitment thereof, as well as the nature of the development projects it finances.

In recognition of its work, in November 2017, CABEI received the award for "Best Green Issuer in Latin America" from the Capital Finance International (CFI) magazine based in London, England. In its press release, the magazine highlighted the Bank's pioneering role in financing its partner countries to help them adopt mitigation and adaptation practices to climate change. The financing role includes, among others, the issuance of green bonds and their accreditation to the Green Climate Fund, in order to increase the flow of financial resources to their member countries to face climate change.
