Guyana and the Dominican Republic have signed a Memorandum of Understanding that sets up a framework for cooperation on sustainability and decarbonisation in civil aviation. Guyana’s Minister of Public Utilities and Aviation, Deodat Indar, put his signature to the memorandum on his country’s behalf. . Miguel Amaurys Mejia Capellan, Deputy Director of the Dominican Institute of Civil Aviation, signed for the Dominican side.

The official statement gives no date or place for the signing. The Aviation Operators Association of Guyana mentioned the memorandum in a statement congratulating the government on the Global ICAO and European Union Aviation Safety Agency safety conference, held in Guyana on September 29 and 30, 2026, and a Caribbean aviation safety symposium on October 1. The association said the memorandum showed Guyana's growing role in regional and international aviation. It also reported that air services agreements with Greece, Panama and France were signed during that period.

The memorandum is aligned with the Carbon Offsetting and Reduction Scheme for International Aviation, known as CORSIA, which is run by the International Civil Aviation Organisation (ICAO). The scheme covers emissions from international flights only. Airlines taking part in the scheme purchase credits to make up for emissions above the agreed limit.  The official statement says the memorandum also supports the global goal of net-zero carbon emissions by 2050.

Sustainable aviation fuels receive priority. These are produced from sources such as waste oils and plant material and are blended with conventional jet fuel. The memorandum also names the reduction of carbon emissions and the mobilisation of climate finance, meaning money raised to pay for emissions-reduction work, as aims. The statement gives neither figures to be met nor dates for meeting them. 

Cooperation is to include the exchange of technical expertise and capacity building. The two countries also intend to develop Eligible Emissions Units that comply with CORSIA, and they have committed to preventing double counting of emission reductions under the Paris Agreement. Double counting would arise if the same reduction were credited towards the climate commitments of two parties.

A Joint Working Group will convene annually. Each country will finance its own activities under the memorandum. The statement mentions no shared fund and no agreed sum, and it gives no estimate of what either government expects to spend.

Both countries already take part in CORSIA. A working paper presented by Guyana to ICAO's 41st Assembly said Guyana had opted in to the scheme's pilot phase, while describing the international emissions of Guyana-based carriers as negligible. ICAO's 2025 environmental report says the Dominican Republic joined in October 2018.

The two aviation authorities have worked together before. Guyana's Civil Aviation Authority said it signed a memorandum on technical cooperation with its Dominican counterpart at the ICAO Air Services Negotiation Event held in Punta Cana in 2025, with the stated aim of improving aviation systems in both countries. That event also produced six air services agreements between Guyana and other states, according to the authority.

It is unclear from the statement whether the full text of the memorandum has been made public.
