INTERNATIONAL PAPER CO NEW

The Company recognizes the impacts of climate change on people and our planet. To manage climate-related risks, we are taking actions throughout our value chain to help advance a low-carbon economy. We aligned our annual sustainability reporting with the recommendations of the Task Force on Climate-Related Financial Disclosure (“TCFD”) in the 2023 reporting cycle (based upon data from 2022). As part of our TCFD reports, we identify and report on climate-related opportunities. We identify and evaluate physical and transition climate-related risks through our enterprise risk management process.

We transform renewable resources into recyclable products that people depend on every day. We aim to produce low carbon products that have a positive impact on nature. To this end, we source renewable fiber from responsibly managed forests and recycled raw materials. We then use a circular manufacturing process that makes the most of resources and byproducts, while reducing the environmental impacts of our operations. At the end of use, the majority of our low-carbon fiber-based products are recycled into new products at a higher rate than any other base material. We work to advance the shift to a low-carbon, circular economy by designing products that are 100% reusable, recyclable or compostable.

Through improvements in operations, equipment, energy efficiency and fuel diversity, we are working to achieve company-wide reductions in Scope 1 and Scope 2 greenhouse gas (“GHG”) emissions. As part of our Vision 2030 goals, we have targeted incremental reductions of 35% in our Scope 1, 2, and 3 GHG emissions by 2030 in comparison to 2019 levels. The Science Based Targets initiative (“SBTi”) approved these targets as consistent with levels required to meet the goals of the 2015 Paris Agreement, an agreement signed among over 170 countries, which became effective in November 2016. We intend to continue to evaluate and implement projects as we pursue this Vision 2030 GHG goal. This includes ongoing energy efficiency efforts and capital projects to phase out our most carbon intensive fuel sources (Scope 1) as well as developing GHG reduction strategies for our energy sourcing (Scope 2) and broader supply chain footprint (Scope 3). In addition, we have recently committed to be an early adopter of the Taskforce on Nature-related Financial Disclosures (“TNFD”). TNFD adopters intend to make corporate reporting disclosures that are aligned with TNFD recommendations, which have been designed to (i) meet the corporate reporting requirements of organizations across jurisdictions; (ii) be consistent with the global baseline for corporate sustainability reporting; and (iii) be aligned with the global policy goals outlined in the Kunming-Montreal Global Biodiversity Framework, which was adopted to halt and reverse nature loss by 2030.

We use carbon-neutral biomass and manufacturing residuals (rather than fossil fuels) to generate a majority of the manufacturing energy at our mills. We believe our efforts to advance sustainable forest management and restore forest landscapes are an important lever for mitigating climate change through carbon storage in forests.

INTERNATIONAL EFFORTS

The 2015 Paris Agreement compels international efforts and voluntary commitments toward reducing the emissions of GHGs. IP supports the 2015 Paris Agreement and recognizes the importance of global policy action to achieve emission reductions consistent with an increase of “well below 2 ° Celsius above pre-industrial levels and to pursue efforts to limit the temperature increase even further to 1.5 ° Celsius.” Consistent with this objective, participating countries aim to balance GHG emissions generation

and sequestration in the second half of this century or, in effect, achieve net-zero global GHG emissions.

To assist member countries in meeting GHG reduction obligations, the European Union operates an Emissions Trading System ("EU ETS"). Our operations in the EU experience indirect impacts of the EU ETS through purchased power pricing. Neither the direct nor indirect impacts of the EU ETS have been material to the Company, but they could be material to the Company in the future depending on how the 2015 Paris Agreement's non-binding commitments or allocation of, and market prices for, GHG credits under existing rules evolve over the coming years.

Additionally, the EU’s newly mandated Corporate Sustainability Reporting Directive (“CSRD”) and Deforestation Regulation (“EUDR”), each impose additional compliance responsibilities on the Company. The CSRD requires additional reporting processes for greater accountability. The Company’s first reporting year under the CSRD is expected to be 2025. The CSRD standards replace the existing Non-Financial Reporting Directive and expands reporting requirements for companies operating in the EU. The implementation timeline varies depending on the type of entity.

The EUDR requires companies trading in products derived from certain commodities to conduct extensive diligence on the value chain to ensure goods do not result from recent deforestation, forest degradation or breaches of local environmental and social laws. Currently, the Company is evaluating the implications of the EUDR to its business with the expected earliest reporting date being in 2025.

U.S. EFFORTS, INCLUDING STATE, REGIONAL AND LOCAL MEASURES

Responses to climate change may result in regulatory risks as new laws and regulations aimed at reducing GHG emissions come into effect. The EPA manages regulations to: (i) control GHGs from mobile sources by adopting transportation fuel efficiency standards; (ii) control GHG emissions from new Electric Generating Units (“EGUs”); (iii) control emissions from new oil and gas processing operations; and (iv) require reporting of GHGs from sources of GHGs greater than 25,000 tons per year.

Several U.S. states, including states in which we operate facilities, have enacted or are considering legal measures to require the reduction and reporting of emissions of GHGs by companies and public utilities. California, New York and Virginia have already enacted such programs, although these regulations have not had, and are not expected to have a material impact on the Company. For example, the State of California recently passed the Climate Corporate Data Accountability Act and the Climate-Related Financial Risk Act, which will impose climate-related reporting obligations on companies doing business in California meeting specified thresholds, including the Company. We monitor proposed programs in other states as well; however, it is unclear what impacts, if any, future state-level or local GHG rules will have on the Company’s operations.

SUMMARY

Regulation related to GHGs and climate change continues to evolve in the areas of the world in which we do business. However, while it is likely that there will be increased governmental action regarding GHGs and climate change in the future, it is unclear what actions will be taken and when such actions will occur and at this time it is not reasonably possible to estimate the Company’s costs of compliance with rules that have not yet been adopted or implemented and may not be adopted or implemented in the future. In addition to possible direct impacts, future legislation and regulation could have indirect impacts on the Company, such as higher prices for transportation, energy and other inputs, as well as more protracted air permitting processes, causing delays and higher costs to implement capital projects. Other possible indirect impacts may include influence on competitive position due to customer and end-consumer preferences regarding low-carbon, circular products with a high recycling rate along with tax credit and funding opportunities to expand green energy production and carbon credit generation. The Company has controls and procedures in place to track GHG emissions from our facilities, as well as to stay informed about developments concerning possible climate-related laws, regulations, accords, and policies in the U.S. and in other jurisdictions where we operate. We regularly assess whether such developments may have a material effect on the Company, its operations or financial condition, and whether we have any related disclosure obligations under applicable rules and regulations.

Moreover, compliance with legal requirements related to GHGs and/or climate change which are currently in effect or which may be effective or enacted in the future are expected to require future expenditures to meet GHG emission reduction, disclosure or other obligations. These obligations may include carbon taxes, the requirement to purchase GHG credits or the need to acquire carbon offsets. We may also incur significant expenditures in relation to our efforts to meet our internal targets or goals with respect to

GHGs and climate change, including our Vision 2030 goal on GHGs as set forth above. Furthermore, in connection with complying with legal requirements and/or our efforts to meet our internal targets and goals, we have made and expect to continue to make capital and other investments to displace traditional fossil fuels, such as fuel oil and coal, with lower carbon alternatives, such as biomass and natural gas. Rather than rely on carbon offsets, we focus on reducing energy consumption as well as relative GHG emissions across our mills and manufacturing facilities. Currently, these efforts and obligations have not materially impacted the Company but such efforts and obligations may have a material impact on the Company in the future.

We believe sustainability is a key element of corporate governance promoted by our Board of Directors, committees of the Board of Directors, and senior management.

Our Board of Directors has primary oversight of the Company's enterprise risk management program, which includes sustainability. The Board receives updates from our Chief Sustainability Officer ("CSO") and additional members of management. Our Board of Directors also conducts periodic reviews of components of the sustainability strategy and performance and reviews material key sustainability-related developments and issues. Our standing committees share responsibility on sustainability as described below:

Audit and Finance Committee

•Reviews processes and controls for external reporting of sustainability and social impact data and metrics.

•Reviews related disclosures in Annual Report on Form 10-K and other sustainability reports.

Governance Committee

•Reviews and reassesses adequacy of, and oversees compliance with our Corporate Governance Guidelines.

•Seeks Board of Director candidates with diverse backgrounds.

Management Development and Compensation Committee ("MDCC Committee")

•Approves Chief Executive Officer ("CEO") sustainability-focused objectives and evaluates performance.

•Considers sustainability factors in SLT compensation and in overall compensation plan design.

•Reviews sustainability disclosures related to executive compensation.

Public Policy and Environment Committee ("PPE Committee")

•Reviews sustainability and social impact policies, plans and performance to ensure commitments to stewardship.

•Stays current on emerging sustainability and social impact trends and issues impacting the Company.

At the management level, ownership and governance of sustainability matters is embedded in the organization from the top down. Our CEO and SLT are responsible for corporate strategy and leadership including incorporation of our sustainability goals and standards into our daily operations and long-term business strategy. Our SLT, which is comprised of senior vice presidents who oversee critical functions and business units within the Company, evaluates sustainability issues based on input from function-specific councils that report to the SLT. The SLT receives several sustainability updates throughout the year from our CSO. The Company also has an Enterprise Lead Team (“ELT”), comprised of the SLT and additional subject matter experts, including our CSO, that meets quarterly and receives regular climate-related updates. Moreover, at the operational level, our Stewardship Council, a cross-functional leadership team with representatives from businesses and functional teams, guides and supports the Company’s sustainability strategy and tactics.
