Sustainability and Community Update

Airbnb aspires to operate as a true 21st century company that benefits all of our stakeholders-our Hosts, our guests, the communities in which we operate, our employees and our shareholders. Our responsibility to our stakeholders guides how we operate: we strive to design for the long-term benefit of all stakeholders, monitor our progress, and adjust when we don't get it right. We believe that operating in this way will allow us to build a highly valuable business over the long run.

This report outlines some of the work we have undertaken to serve our stakeholders, which includes, but is not limited to:

• Our work to build a more sustainable company and community, including our commitment to identify and reduce our greenhouse gas emissions.
• A series of initiatives designed to make Airbnb a place where people of all backgrounds, iden- tities, and experiences can succeed and thrive.
• Building trust, working to keep our community safe, and protecting our Hosts' and guests' privacy, both online and in the real world.
• Strengthening the communities our Hosts and guests call home.

This update builds upon our updates from December 2021and September 2022. More information about our work to support stakeholders can be found in the Airbnb Newsroomand in our quarterly Shareholder Letters, which are on our Investor Relationswebsite.

Environmental Sustainability

We believe addressing climate change is one of the greatest challenges of our generation and that businesses play a key role in helping to achieve a stable climate. We also believe that striving for more sustainable operations-and sustainable practices with our Hosts and guests-is an important tool to help address stakeholder concerns, reduce energy costs, increase business resiliency, and create a more sustainable company and community.

Highlights of our recent environmental sustainability progress include:

• Airbnb's corporate, absolute emissions1 were approximately 17 percent lower in 2022 than they were in 2019, which serves as our baseline year.
• Working with suppliers to address key sources of our emissions through the Airbnb Supplier Sustainability Program.
• Expanding and diversifying our carbon credit purchases,
  including increasing purchases from nature-based emissions removal projects.
• Launching pilot programs across the UK, France, and the United States to help our Hosts make their homes more energy efficient.

Additional information regarding our work to make our company and community more sustainable is included below.

1. Unless stated otherwise, references to Airbnb's "emissions" means Airbnb's corporate, absolute (i.e., total) greenhouse gas emissions in MTCO2e for our global operations. The specific catego- ries of emissions included are Scope 1, Scope 2,

and the following Scope 3 categories defined by the GHG Protocol: 3.1 Purchased goods and

1services, 3.2 Capital goods, 3.3 Fuel- and energy -related activities (not included in Scope 1 or

Scope 2), 3.5 Waste generated in operations, 3.6 Business travel, 3.7 Employee commuting, and

3.8 Upstream leased assets). Airbnb's absolute emissions statements also include the purchase of energy attribute certificates (i.e., renewable energy certificates, guarantees of origin, or simi- lar instruments) to mitigate the total greenhouse gas emissions from our global operations. See Appendix Afor more detail.

Airbnb has set aggressive greenhouse gas emissions reduction targets and implemented a broad range of initiatives designed to decarbonize our business and make our corporate operations more sustainable. Some of these initiatives are summarized below.

Corporate Net Zero Goal

In 2021, we committed to a goal to operate as a net zero company2 by 2030, reducing greenhouse gas emissions associated with our global Scope 1, 2, and 3 corporate operations and investing in quality solutions to offset residual emissions, including those with a focus on nature-based solu- tions. We are proud to share that our 2022 emissions were below both our annual target and our emissions in our baseline year of 2019 (for more details see "Measuring our Progress"). We also increased our purchases of carbon credits by approximately 37 percent year-on-year, in line with our plans to gradually increase credit purchases (with a focus on nature-based solutions) leading up to 2030.

100 Percent Renewable Electricity

In 2020, we committed to achieve 100 percent renewable electricity3 use for our corporate operations. We have fulfilled this commitment for three consecutive years by matching our office electricity use (Scope 2 and Scope 3, Category 8) with renewable electricity purchases, the vast majority of which meet the standards of RE1004, an organization we joined in 2021.

The COVID-19 pandemic changed the way our employees live and work. Adapting to this new reality, in 2021, we started sourcing and retiring 100 percent renewable electricity to match the estimated electricity use associated with employees working from home.5 In addition, in 2021 and 2022, we offered renewable electricity options to eligible US employees who signed up for the offering to help them to further reduce their at-home emissions.

2. The specific categories of emissions included in our corporate net zero goal (which we also refer to as our "net zero goal") are the emissions Scopes and Categories outlined in Footnote 1.

3. Airbnb joined the RE100 in 2021 and committed to sourcing renewable electricity for our Scope 2 electricity consumption according to RE100 standards. In addition, we also source renewable electricity to match the electricity consumption associated with the offices that are considered upstream leased assets (Scope 3, Category 8) even though these purchases are not able to be reflected as Scope 3 emissions reductions under current GHG Protocol guidance.

4. We have matched our global corporate office electricity consumption with renewable electricity for 2020-2022 by purchasing and retiring energy attribute certificates (i.e., renewable energy certificates, guarantees of origin, or similar instruments) sufficient to match 100 percent of our electricity consumption for those years. Specifically with regard to the RE100

	technical criteria, Scope 2 renewable electric-
	ity sourced was approximately 88, 100 and 99
2	percent compliant with the RE100 technical

criteria for 2020, 2021 and 2022, respectively. (Our 2020 renewable energy purchases are not reflected in our 2020 Scope 2 GHG emissions measurement because the energy attribute certificates had not been delivered at the time we completed our emissions inventory for that year.) Where renewable electricity was not

100 percent compliant with the RE100 technical criteria, it was due to challenges sourcing renewable electricity locally in certain markets due to lack of availability and low volumes. In these instances, the energy attribute certificates were procured from reasonably comparable and geographically near markets outside of the RE100 guidance on market boundaries.

5. We are addressing employee work-from-home electricity consumption even though renewable energy purchased for these initiatives is typically not able to be reflected as Scope 3 emissions reductions under GHG Protocol guidance.

We continue to take steps to evolve our approach to meeting our RE100 commitment, with the goal of sourcing renewable electricity through methods with more direct impact on the grids where we consume power. For example, in 2021 we installed rooftop solar panels at our Gurgaon, India office. Additionally, in 2023, we transitioned to CleanPowerSF's SuperGreen program at our primary San Francisco headquarters building. This enables Airbnb to opt into 100 percent renewable electricity supply from California wind and solar for that building, which accounts for approximately 16 percent of our global office electricity consumption. Our teams are actively working to explore similar alternatives at other locations.

The Airbnb Supplier Sustainability Program

Like many companies, Airbnb's suppliers represent the largest portion of our emissions - in 2022, supplier emissions (Scope 3, Category 1) accounted for approximately 96 percent of our emis- sions. That's why we launched the Airbnb Supplier Sustainability Program in 2022. This program aims to have the suppliers that represent the largest portion of our emissions commit to measure, report, and ultimately reduce their greenhouse gas footprint.

• In 2022, supplier emissions accounted for approximately 96 percent of our emissions.
• To date, the Airbnb Supplier Sustainability Program has engaged with nearly 70 suppliers.
• This represents approximately 61% of Airbnb's 2022 corporate emissions.

To date, we have engaged nearly 70 suppliers, representing approximately 61 percent of Airbnb's

2022 corporate emissions, in the first phase of this program. As part of this engagement:

• Suppliers representing approximately 31 percent of Airbnb's 2022 emissions have committed to measure, report, and-if they don't have approved near-term targets from the Science Based Targets initiative or similar emissions reduction goals-reduce their emissions footprint.
• Over 66 percent of these suppliers submitted their emissions and other climate-related infor- mation to CDP's6 2023 Climate Change Questionnaire at our request. Notably, of the suppliers reporting to CDP, approximately 23 percent were reporting to CDP for the first time.

Looking ahead, we are expanding the Airbnb Supplier Sustainability Program to include additional suppliers, and we plan to provide additional educational tools and resources to suppliers as they work to deliver on their commitments. We will closely monitor our suppliers' progress towards their sustainability commitments and reassess our contracts and spending with companies that fail to make progress against the goals of the Supplier Sustainability Program.

While addressing the largest source of our emissions will help us make progress toward our sustainability goals, we anticipate that working with our suppliers in this way can allow them to advance

their own sustainability work. Our hope is that this helps move the entire business community towards a more sustainable future, together.

Sustainability in our Offices and their Operations

In addition to sourcing renewable electricity for our offices, our teams are working to make our buildings and how we operate them more sustainable. For example:

• In 2023, our teams completed detailed building sustainability audits for our primary San Francisco headquarters and at our Dublin and Seattle offices. These audits involve detailed, on-site reviews of each building, its energy usage and systems, and an assessment of oppor- tunities for energy savings. As a direct outcome of these efforts, we are investing in building upgrades to our primary headquarters to increase building energy efficiency and are explor- ing upgrades at the Dublin and Seattle offices.
• Sustainability is a core principle of our office food program. The Airbnb Workplace Operations team reduces waste by favoring bulk items versus packaged foods, utilizing reusable table- ware in large offices, and repurposing ingredients. To reduce emissions and support our local communities, the team aims to purchase food primarily from local vendors located within a 100-mile radius of offices.

We strive to avoid sending waste to landfills. In addition to our food composting efforts and our recycling programs at all offices directly operated by Airbnb, we seek to donate to nonprofits or allow employees to take home items no longer needed by the company, such as kitchen supplies and IT equipment, when possible.

Employee Business Travel and Commuting

With many employees now choosing to work from home, emissions from employee commuting have significantly decreased from pre-pandemic levels. Additionally, we have evolved our business travel policies and purchased nature-based emissions removal credits to cover 100 percent of our 2022 employee business travel emissions. We intend to take this step again for all employee business travel in 2023.

Carbon Credits7

We believe carbon credits are more than just a means to help achieve our 2030 net zero goal. Carbon credits, especially nature-based solutions, are valuable tools that can allocate critical investment in the fight against climate change while achieving additional beneficial environmental outcomes. We recognize this is an evolving field where approaches and standards may change over time and we aim to work with leading tools and experts to incorporate scientific and regulatory requirements.

7. We use the term "carbon credits" to mean annually generated units of avoided or sequestered (removed) greenhouse gases denominated in metric tons of carbon dioxide equivalent. The credits are produced by projects that undertake specific activities, such as forest protection or reforestation, and we aim to source projects that are reviewed and accredited by reputable, independent third-

party standards organizations.

To direct our spending to carbon credits that are high-quality and high-integrity, we endeavor to purchase from nature-based projects that accomplish the following:

• Additionality: Reductions from the carbon credit would not have occurred without revenue from its sale.
• Permanence: Avoided emissions or emissions removals that
  are more likely to trap greenhouse gases for an extended period of time.
• Monitoring: Carbon credits are accompanied by ongoing monitoring and verification of impacts and outcomes.
• Co-benefits:Projects that deliver additional social and environmental benefits, such as new sources of income for local communities and protecting or restoring biodiversity.
• Integrity: Projects that demonstrate efforts to screen their financial sponsors and credit buy- ers, involve local stakeholder participation, and seek fair distribution of credit revenues.

In addition to screening projects ourselves, whenever possible, we aim to work with third-party aggregators who provide further vetting, which increases our confidence in credit quality and social and environmental co-benefits.

We began purchasing carbon credits in 2021, and plan to gradually increase our purchases every year as we approach our 2030 net zero goal. In 2022, we:

• Increased our carbon credit purchases by approximately 37 percent from the prior year, diversifying beyond forest protection and reforestation to include investments in projects that collect and destroy potent global warming gases other than carbon dioxide. Some of these gases are hundreds of times more damaging than carbon dioxide and, unlike carbon dioxide, cannot at scale be absorbed naturally or removed from the atmosphere with capture technology.
• Continued our participation in the LEAF Coalition, helping to accelerate funding of efforts to address tropical deforestation in sub-Saharan Africa through high-quality carbon credits.
• Purchased enough nature-based emissions removal credits to account for all of 2022 employee business travel.

Through these efforts, we also focus on supporting projects in the cities and towns where our Hosts and guests live. These local projects present an opportunity for urban greening, and can help make communities more resilient to adverse climate events. As part of our work, we are developing long-term partnerships to align positive climate action with the needs of Indigenous Peoples and Local Communities (IPLCs), such as our partnership with the National Indian Carbon Coalition (NICC). Notably, reports have indicated that landscapes around the world that are governed by IPLCs have sequestered more than double the amount of carbon dioxide as landscapes not under their control.8

Supporting Nature-Based Projects

These are examples of nature-based projects from which we purchased carbon credits in 2022.

Delta Blue Carbon mangrove restoration project in Pakistan

The Delta Blue Carbon mangrove restoration project in Pakistan engages local communities in replanting decimated forests. In addition to increasing forest cover, mangroves have been recognized as a valuable natural physical barrier that can dampen the impacts of floods. The project was also recently endorsed by the Government of Pakistan for international carbon accounting under UN-negotiated trading protocols.

Improving Forests on Tribal Lands

The National Indian Carbon Coalition (NICC) supports traditional stewardship on Native American lands in Michigan and Minnesota by managing invasive species and committing to sustainable harvesting practices. The NICC has also stated that revenue from NICC carbon credits supports local economic development.

Measuring Our Progress

We are focused on reducing our emissions and have established aggressive 2030 emission reduction targets from our 2019 baseline year. These targets were approved by the Science Based Targets initiative (SBTi) under the near-term target criteria as consistent with levels required

to meet the goals of the Paris Agreement. Airbnb's revenue increased 75 percent from 2019 to 20229, and our emissions have decreased from 2019 levels, thanks to our efforts to operate a more disciplined business and our sustainability initiatives.

Scope 1 and 2 Emissions

Airbnb established a near-termscience-based target to reduce Scope 1 and 2 (direct emissions from stationary combustion and refrigerants and indirect emissions from purchased electricity, diesel generators and district heat, respectively) absolute emissions by 78.4 percent by 2030 from our 2019 baseline. While our Scope 1 emissions increased from 202110 levels due primarily to an expansion of our reporting boundary to include refrigerants as a source of emissions, as of year-ended 2022, Airbnb achieved a nearly 81 percent reduction of our Scope 1 and 2 absolute emissions compared to our 2019 baseline, due to our continued matching of our office electricity use with 100 percent renewable energy purchases. Therefore, we continued to meet

- and exceed - our Scope 1 and 2 near-termscience-based targets.

Scope 3 Emissions

The vast majority of Airbnb's emissions are Scope 3 (indirect emissions that occur in our value chain), and are largely attributable to the goods and services we obtain from our suppliers (e.g., professional services, advertising and marketing services, customer support services, etc.). Approximately 96 percent of our 2022 emissions were associated with our suppliers.

We established a near-termscience-based target of reducing Scope 3 emissions intensity (MtCO2e/$1 million gross profit11) by 55 percent by 2030 from our 2019 baseline. Despite significant business growth from 2019 to 2022, Airbnb reduced our 2022 Scope 3 emissions intensity by nearly 56 percent compared to 2019.

The progress we have made in reducing our emissions intensity significantly from 2019 levels can be attributed to a range of factors, including the growth in our business, the steps we have taken to make our business leaner and more efficient, as well as our ongoing focus

on sustainability. We've recognized further emissions intensity reductions from increases of renewable electricity usage among certain key suppliers, such as cloud providers, and increased efficiency of cloud usage.

9.	AirbnbQ4 2022 Shareholder Letter.
10.	2022 scope 1 emissions were approximately
	50% higher than 2021 due to changes of report-
	ing boundary and measurement methods.
11.	Scope 3 emissions intensity measured using
	the economic intensity method as set by SBTi's
	Greenhouse Gas Emissions per Value Added
	(GEVA). SBTi provides that the term "value
	added" can be defined as gross profit, operat-
	ing profit, revenue minus the cost of purchased
7	goods and services, or earnings before interest,
taxes, depreciation, and amortization (EBITDA)

plus all personnel costs. "Gross profit" for purposes of Airbnb's emissions intensity measurement is calculated as revenue minus cost of revenue as reported in Airbnb's Annual Report on Form 10-K.
