ADOC 2022 SUSTAINABILITY REPORT

Mubarraz Blue Carbon Study

When mangroves are damaged or destroyed, significant amounts of carbon are released into the atmosphere,
which, along with the loss of their ability to store carbon, contributes to global warming. Besides their climate-
related benefits, blue carbon ecosystems also provide a host of other valuable ecosystem services, such as
shoreline protection, habitat for biodiversity and nursery ground for fish and crustaceans.

According to studies conducted all over the world, mangroves typically store five times as much carbon as a
comparable area of rainforest. At the global level, seagrass meadows play a significant role as carbon sinks by
storing large amounts of carbon in the sediment and seagrass vegetation.

In June 2022, ADOC collaborated with relevant specialist with a request to prepare a proposal for a study
to investigate the gradual build-up with time of blue carbon storage capacity in the mangroves planted by
ADOC over the years and to make an assessment of the total blue carbon stock in the mangrove and seagrass
ecosystems at Mubarraz. This study will provide us with quantitative data on carbon storage that will provide the
result of our efforts to plant mangroves and protect seagrasses at Mubarraz (a positive environmental impact).

The proposed scope of work consists of a field investigation to assess the total amount of blue carbon stock in
the Mubarraz mangrove ecosystems as well as the gradual development and build-up (over time) of blue carbon
storage capacity in the vegetation and soil of the mangroves planted by ADOC over the years. The total blue
carbon stock in the seagrass ecosystems at Mubarraz will also be measured through a field study of carbon stocks
in seagrass vegetation and underlying sediment. Once the study comes to an end, a technical report will be issued.

GHG emissions and flaring, are referred to as direct emissions. Indirect
emissions refer to those from purchased utilities (activities
associated with electricity, steam, heat, or cooling) from
ADOC’s direct GHG emissions (Scope I) and indirect ADWEA. The “Method for Estimating Atmospheric
GHG emissions (Scope 2) decreased by 1.68% in 2022. Emissions from E&P Operations’’ was used to calculate
The annual emissions of carbon dioxide (CO ), methane GHG emissions by converting the net energy consumed
