OTHER EMISSIONS
G4-EN20, G4-EN21
In addition to greenhouse gas emissions, Braskem manages other air
emissions within its responsibility, such as ozone-depleting 27 substances
and pollutants from fuel combustion, such as NOX, SOX, and others.

ENGAGEMENT OF SUPPLIERS
IN EMISSIONS REDUCTION
Braskem does not have mandatory requirements
for its Suppliers, but has been developing voluntary
engagement initiatives for the past five years as a
means of more efficiently managing GHG emissions
and the risks and opportunities in the chain
upstream. Actions to raise awareness, encourage
the preparation and reporting of an emissions
inventory, and identify risks and opportunities are
carried out annually with support from CDP Supply
Chain. As a result, there has been significant
evolution regarding the representativeness of
Scope 3 emissions.

(1)The methodologies used are recommended by state environmental agencies. Where there
is no measurement, estimates (emission factors) based on recognized methods, such as
AP-42 from USEPA, are used.
(2) The plants have been expanding their assessments, which explains the increase in these
parameters.
(3) Includes Toxic Air Pollutants and HAP
(4) Includes total hydrocarbons and carbon monoxide.
