Who is PubMatic?

PubMatic is a NASDAQ-listed digital advertising technology company, operating a complex global infrastructure of data centres and programmatic platforms.

As a trusted partner to some of the world’s largest brands and publishers, the company faces growing pressure to align with climate-conscious customers and investor expectations.

The Challenge:

PubMatic needed to overcome key barriers to accelerate climate action:

  • Understanding its carbon footprint across a distributed, digital-first operation.
  • Finding a reliable, science-based and cost-efficient pathway to decarbonise digital activities.
  • Ensuring that any action taken enhanced rather than burdened commercial teams.
  • Validating their strategy in line with external standards such as the SBTi.

The Goals:

  • Quantify and reduce core operational emissions.
  • Secure validated Science-Based Targets to anchor long-term ambition.
  • Improve audit readiness while freeing up internal resources.
  • Build commercial credibility to support new business from climate-conscious advertisers.

PubMatic partnered with 51toCarbonZero to deliver an efficient and commercially aligned climate programme:
  • Consolidated and analysed emissions data across complex digital infrastructure.
