Global Sustainability Snapshot 2024

Building a More Efficient and Effective Advertising Supply Chain

A thriving open internet must be built on a responsible foundation. We measure our global carbon footprint annually to assess the progress of our long-term environmental sustainability strategy. We are excited to share the results in our 2024 sustainability snapshot.

Sustainability Statement

At PubMatic, we understand that long-term efficiency and responsibility go hand in hand. As the advertising industry evolves, we continue to integrate sustainability into our technology and operations and leverage environmental impact in our decision-making. By considering carbon impact alongside performance metrics, we believe we can achieve our goal of building a more efficient and effective advertising supply chain that benefits both our partners and the planet.

Global Carbon Footprint

In partnership with climate and media experts at 51 to Carbon Zero, we assess our global carbon footprint in accordance with the Greenhouse Gas (GHG) Protocol, including:

  • Scope 1 — direct emissions from sources owned or controlled by PubMatic
  • Scope 2 — indirect emissions from purchased energy consumed by PubMatic
  • Scope 3 — indirect emissions from our business operations and supply chain

Data Center Sustainability

Digital advertising is inherently high volume, data-rich and energy-intensive—especially as generative AI becomes increasingly integrated across the ecosystem. At PubMatic, we view data center sustainability as essential to delivering long-term efficiency and performance.

In 2024, through partnership with our colocation vendors and the use of renewable energy credits (RECs), we re-achieved a major milestone: 100% renewable energy coverage across our global data centers.

At the same time, we expanded the use of Generative AI across our technology stack. By optimizing our infrastructure, we increased gross impression capacity on our platform by 20% while lowering our cost of revenue through infrastructure optimization, demonstrating that sustainable operations and business growth can go hand-in-hand.

Business Operations Sustainability

At PubMatic, we continue to prioritize sustainable business operations as part of our broader efficiency and growth strategy.

As our workforce scaled to over 1,000 people in 2024 to support business growth, we continued to manage our environmental impact through process improvements and efficiency initiatives. For example, while in-person collaboration remained an important part of how we do business both internally and with clients, we maintained responsible travel practices and supported hybrid engagement models where possible.

Note that Scope 3 emissions related to business travel appear significantly higher year-over-year. This increase is driven primarily by the adoption of improved data collection methods, providing greater accuracy rather than reflecting a material increase in travel activity.

A key milestone in 2024 was the validation of our short-term and net zero targets by the Science Based Targets initiative (SBTi). This validation affirms that our operational efficiency goals are aligned with the latest climate science, ensuring that we achieve our growth strategies while simultaneously contributing to a sustainable future.

Looking Forward

Looking ahead, operational efficiency will remain a foundational pillar of our business strategy. In 2025 and beyond, we will continue investing in ways to enhance performance, reduce costs, and scale responsibly. As we expand our usage of gen AI across our platform and technology suite, we will also deepen collaboration with partners across the digital ecosystem to build a more resilient, sustainable, and efficient supply chain.

Methodology

51 to Carbon Zero assessed our business operations in alignment with the GHG Protocol reporting standards. We followed an Operational Control approach and reported on everything PubMatic has complete authority to create and apply operating policies. The analysis included the following categories:

Scope
Emission Category
Date Source
Scope: Scope 1
Emission Category: Stationary Fuel Combustion
Date Source: Meter readings or receipts from landlords and colocation providers when available, or via proxy calculation based on square footage
Scope: Scope 2
Emission Category: Purchased Electricity
Date Source: Meter readings or receipts from landlords and colocation providers when available, or via proxy calculation based on square footage
Scope: Scope 3
Emission Category: Purchased Goods & Services
Date Source: Accounting reports and spend based emission factors of key activities contributing to emissions
Scope: Scope 3
Emission Category: Capital Goods
Date Source: Accounting reports and relevant manufacturing emissions factors for each product
Scope: Scope 3
Emission Category: Fuel & Energy Related Activities
Date Source: Upstream emissions data of scope 1&2 energy consumption
Scope: Scope 3
Emission Category: Business Travel 1
Date Source: Travel agent reports and relevant distance-based emissions factors
Scope: Scope 3
Emission Category: Employee Commuting
Date Source: Employee survey responses and a global emission factor approach for each mode of transportation
Scope: Scope 3
Emission Category: Working from Home
Date Source: Employee survey responses and regional emissions factors for office equipment, heating and cooling

1In 2024, we enhanced data capture and reporting granularity related to business travel emissions to provide a more complete view of PubMatic’s Scope 3 impact. As a result, this category’s emissions appear signficiantly higher year-over-year.
