2022 GREENHOUSE GASES INVENTORY
GRI 201-2,305-1, 305-2, TCFD Risk Management a., Metrics and Targets b.
The Greenhouse Gas (GHG) Emissions Inventory is the first tool by which
an institution can start to understand its emissions profile and it can then
use it to take the necessary measures to reduce its emissions. Since
2014, Orizon has published an inventory on its Rio de Janeiro ecoparks'
emissions of greenhouse gases, and, since 2022, for all its operational
units. The methodology for calculating Orizon's GHG emissions is based
upon the Brazilian GHG Protocol Program, which, in turn, uses studies
presented in the IPCC - Guidelines For National Greenhouse Gases
Inventories as a base.
As of 2022, the Brazilian GHG Protocol Program started to adopt the
updated calculation methodology in accordance with the directives
of the IPCC for waste sent to landfills, which impacted on Orizon's
emissions results, the most important alterations being as follows:
•
•
•
There was an increase in the emissions of degradable organic carbon
fractions, or in other words, the organic waste placed in landfills rose
from a factor of 0.5 to one of 0.7 of emissions generated;
Inclusion of a new gravimetric classification;
Flare recovery does not convert 100% of the CH into biogenic CO2;
A new portion of the CO2 emissions, relating to the oxidation of
organic material of the highest surface layer of the sanitary landfill.
Due to these methodological alterations and the enormous
growth of Orizon, the emissions of five plants¹, were calculated
in 2021, whilst in 2022 this rose to 16 plants². Considering
these alterations, 2022 was defined as the base year for
the monitoring of the Company's emissions.

1 The Scope 1 emissions in 2021, relating to five plants, totaled 1,489,786.35 tCO2, a
sum that was corrected following the auditing of the Company's 2021 GHG Inventories.
The 2021 Scope 2 emissions, meanwhile, totaled 1,580.35 tCO2.
