2 In the localization approach to electricity purchase, emissions are the product of the multiplication of electricity consumption by the emission factor of
the Brazilian grid (SIN). According to the Ministry of Science, Technology and Innovation, the emission factor of the SIN's electricity generation in 2021
was 0.1264 tCO2/MWh.
We follow our commitment to transparency
through the realization and publication of
the GHG inventory, respecting all applicable
categories established by the GHG Protocol
method. Since 2020, our entire operational chain
has been inventoried, verified by a third party and
disclosed in the Public Emissions Registry (RPE).
In 2020, this process was qualified as Gold by the
Brazilian GHG Protocol Program, recognition of
the highest level in our emissions reporting.
For 2021, we recorded a 6% increase in our
emissions intensity, reaching the regular level
of 0.61 tCO2e/MWh. We consider this increase to
be natural, due to the water shortage that the
electric sector faced in 2021, requiring a greater
dispatch of the various thermoelectric plants
from our generation park in order to help bolster
national energy security. Even so, we recorded a
3% reduction in the intensity of coal emissions
(from 0.90 to 0.87), reflecting the constant
search for efficiency improvements in our assets.
Our intensity is lower than that of other coal-fired
power plants in the United States, whose average
is 1.12 tCO2e/MW, according to data published
by the U.S. Energy Information Administration
(EIA). In the natural gas generation assets, we
registered an increase from 0.45 to 0.49 in
emission intensity, as a result of the higher power
generation of the single-cycle plants (Parnaíba
I, III and IV). Despite the increase, we came in
under the benchmarking of plants using the same
model that, in the United States, for example,
have an average intensity of 0.54.
We continue to pursue actions to boost the
efficiency of our assets so that, over the next
few years, we can reduce the intensity of our
emissions and, moreover, we are aware of the
need to reduce our carbon-equivalent footprint.
Therefore, in 2021 we published our commitments
to achieve net zero in 2050, leading the energy
transition in a fair and comprehensive manner,
without affecting our country's energy security.
Regarding our absolute emissions, we recorded,
in Scope 1, emissions of 7.5 MtCO₂e, a reflection
of the high energy production due to the
water scarcity that the country experienced. In
Scope 2, there was a 26% increase in emissions
due to the resumption of activities in the
administrative offices, due to the flexibilizing
of sanitary protocols and higher dispatch of
energy generation assets. The increase in Scope
3 emissions resulted from the greater amount
of coal being unloaded per ship, also due to the
higher dispatch requirements.

We consider the increase in our Scope 1 emissions to be
natural, due to the water shortage faced by the electricity
sector in 2021 requiring greater dispatch of the different
thermoelectric plants in our generation park in order to
maintain national energy security.
