GLOBAL SUSTAINABILITY SNAPSHOT 2022
A thriving open internet must be built on a responsible foundation. Over the past year, we’ve embarked on
an initiative to evaluate and accelerate our commitment to environmental sustainability as a core pilar of ourholistic approach to responsibility. We are proud to share PubMatic’s inaugural global sustainability snapshot.

We conducted our first global carbon footprint analysis in accordance with the Greenhouse
Gas (GHG) Protocol with the climate and media experts at 51 to Carbon Zero.

DATA CENTER SUSTAINABILITY
Digital advertising is a high volume, data-rich andenergy-intensive industry so focusing on the environmental
sustainability of our data centers has been our top priority.
Through our use of renewable energy at
our owned & operated global data centers,
PubMatic avoided emitting 28.5K tCO2e
into the atmosphere.

BUSINESS OPERATIONS SUSTAINABILITY
As we reopened offices and ramped up business travel in 2022,
efficiency was critical — from both a people and financial standpoint,
as well as an environmental one.
We anticipate an increase in business travel emissions in 2023 as we return topost-pandemic travel, including our Global Sales Conference held each January.

LOOKINGFORWARD

The proactive steps we have taken over the last several years to reduce our carbon footprint represent
the start of our journey. As the 2022 snapshot indicates, our carbon intensity per FTE* is significantly
below industry benchmarks. We intend to go further. We will continue our efforts by developing
science-based targets to decarbonize our operations and run a more sustainable business, thereby
supporting our clients and partners in achieving their own sustainability goals and advancing thedecarbonization of the digital advertising industry as a whole.
As we continue to expand our global business footprint into new markets, particularly in parts of Asia,
renewable energy is less widely available. We will deepen our focus on Scope 2 emissions by actively
engaging with our supply chain across the globe — from data center colocation providers to officelandlords — to reduce our carbon impact by prioritizing renewable energy.

*Based on scope 1 and 2 emissions, plus business travel and waste only, per Ad Net Zero published industry average of 3.4 TCO2e/FTE

Sustainability Contact

51 to Carbon Zero carried out an assessment of our business operations from January 1, 2022 to December 31, 2022, in alignment
with the GHG Protocol reporting standards. We followed an Operational Control approach which involved reporting on everything wherePubMatic has complete authority to create and apply operating policies.
