Atlantica Sustainable Infrastructure : Supplement on ESG to the Integrated Annual Report 2022

Supplement on ESG to the

Integrated Annual Report 2022

About This Supplement on ESG to the Integrated Annual Report 2022

In March 2022, Atlantica issued its Integrated Annual Report 2022 which integrates our financial and non-financial information, including environment, social and governance (ESG) disclosures. This Supplement provides additional environmental, social and governance data which supplements the Integrated Annual Report 2022 and should be read in conjunction with it.

Information included in this Supplement on ESG to the Integrated Annual Report 2022 has been prepared following the same basis and principles than were used in the Integrated Annual Report. Information is as of December 31, 2022, except where otherwise noted. ESG data reported corresponds to all consolidated subsidiaries on a 100% basis, regardless of Atlantica's percentage of ownership in each of the subsidiaries. Currency amounts are expressed in U.S. Dollars unless otherwise noted.

Environment

Net Zero Target

In 2022 our Board of Directors approved a new target to achieve Net Zero emissions by 2040. We target to reduce our Scope 1, Scope 2 and Scope 3 emissions by 90% by 2040 versus base year 2020 and we plan to neutralize the residual emissions to reach net-zero emissions and a state of no impact on the climate from GHG emissions.

Environmental Targets

For the year 2022 we set the following environmental targets:

Description		Unit	2022 Target
Total direct GHG emissions (Scope 1)		metric tonnes of CO2 equivalents	2,063,366
Total indirect GHG emissions (Scope 2) Location		metric tonnes of CO2 equivalents	242,572
Based
Total indirect GHG emissions (Scope 2) Market		metric tonnes of CO2 equivalents	251,066
Based
Total indirect GHG emissions (Scope 3)		metric tonnes of CO2 equivalents	883,776
Direct Nitrogen Oxide (NOx) emissions		metric tonnes	569.97
Direct Sulphur Dioxide (SOx) emissions		metric tonnes	1.0
Direct Particulate Matter (PM) / dust emissions		metric tonnes	4.2
Sulphur hexafluoride (SF6) emissions		metric tonnes	0
Total non-renewable energy consumption		MWh	8,863,196
Total waste disposed		metric tonnes	8,299
Total hazardous waste disposed		metric tonnes	998
Total net fresh Water Consumption		Million cubic meters	9.57
Total net freshwater consumption in water-
stressed areas (Total water withdrawals - Total		Million cubic meters	4.0
water discharges)

Biodiversity Exposure & Assessment

The table below shows a breakdown of our portfolio of assets by number of assets and by hectare.

We have identified all our assets, except for the water assets, as sites used for our own operational activities. Own operational activities include any business activity which may impact natural capital through its own operations, or by depending on critical commodities in its supply chain. Such activities may include power generation and transmission, among others.

We refer to pages 253 and 254 of our Integrated Annual Report 2022 for more detail on our portfolio.

	Number of assets	Hectares
Power generation assets (Own Operational Activities)	31	28,878
Transmission Lines (Own Operational Activities)	7	8,200
Water Assets	3	n/a
Total	41	37,078

Atlantica has assessed each site to identify those that are in proximity to critical biodiversity areas.

The table below shows a breakdown of assets that are in proximity of critical biodiversity areas. Four of our solar plants are close to protected areas, while two of our transmission lines cross some areas that are also considered protected. We refer to page 125 of our Integrated Annual Report 2022 for more detail.

	Number of assets	Hectares
Power generation assets (Own Operational Activities)	4	1,005
Transmission Lines (Own Operational Activities)	2	3,051
Water Assets	0	0

1. While no universal definition exists in international law, the term is used to refer to "tribal peoples whose social, cultural and economic conditions distinguish them from other sections of the national community, and whose status is regulated (wholly or partially) by their own customs or traditions or by special laws or regulations; and to peoples in independent countries who are regarded as indigenous on account of their descent from the populations which inhabited the country (or a geographical region thereof) at the time of conquest, colonization or establishment of present state, and who, irrespective of their legal status, retain some or all of their own social, economic, cultural and political institutions" (ILO, 1989)
