Tim Mohin, Inaugural CEO of the Greenhouse Gas Protocol
Greenhouse gas emissions are now tracked by companies, countries and organisations around the world – but that wasn’t always the case.
The Greenhouse Gas Protocol has created global, standardised frameworks to measure and manage greenhouse gas emissions, working with governments, industry associations, NGOs, businesses and other organisations to continually innovate and update.
Established in the late 1990s by the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD), the GHG Protocol has named its inaugural CEO – Tim Mohin.
“Everything I've done in my career has led to a role like this, and today I'm honored to be named the inaugural CEO of the Greenhouse Gas Protocol (GHG Protocol),” Tim says.
“I am also humbled to be standing on the shoulders of giants through the fantastic people who created the protocol. For more than 25 years, stewarded by WRI and WBCSD, it has become the global framework for measuring emissions across the economy.”
Why the GHG Protocol matters
The Greenhouse Gas Protocol was created to address a simple but critical problem – companies needed a common way to measure and report emissions.
More than two decades later, nearly all disclosing S&P 500 companies report to CDP using GHG Protocol, hundreds of cities across the globe have committed to using the GHG Protocol for Cities and countries around the world work with the organisation on national reporting.
Today, the GHG Protocol provides the most widely used global frameworks for measuring and managing emissions across operations, value chains and mitigation actions. That standardisation is especially important because it gives companies, regulators and investors a consistent language for comparing climate performance.
“The creation of a CEO role reflects the GHG Protocol’s continued evolution and growing role in the global carbon accounting ecosystem,” says Pankaj Bhatia, Global Director, GHG Protocol, who has led the initiative for over 20 years.
“Tim brings strong leadership, supported by a deeply experienced team, to guide the Protocol forward as it scales its impact globally. As I transition from my role and begin the next chapter of my career, I do so with great confidence in the future of the Protocol, with Tim and the team driving this next phase of growth.”
“This is the most important climate infrastructure job in the world, and this is the moment it matters most ”
Tim Mohin’s career
Tim brings deep experience across government, industry and sustainability leadership to his new role.
“I’ve spent my career at the intersection of corporate sustainability and public policy – across government, global business and standards setting,” says Tim.
“The Greenhouse Gas Protocol underpins corporate climate commitments, regulatory disclosure frameworks, net zero targets and carbon markets worldwide. This is the most important climate infrastructure job in the world, and this is the moment it matters most.”
He has more than two decades in corporate sustainability and has held senior roles at Intel, Apple and AMD, where he worked on embedding sustainability into business operations. He also served as CEO of the Global Reporting Initiative from 2017 to 2020, giving him direct experience leading a major standards-setting organisation.
Before his corporate career, Tim worked in public policy, including roles at the US Environmental Protection Agency and the US Senate, where he helped develop environmental policy.
More recently, he has been a Partner and Director of Climate and Sustainability at Boston Consulting Group, advising clients on ESG disclosure, carbon accounting, decarbonisation and transition planning.
“Tim brings deep experience, respected leadership, and a strong understanding of the needs of business and other stakeholders,” said Peter Bakker, President and CEO of the World Business Council for Sustainable Development (WBCSD).
“We look forward to working with him to ensure the GHG Protocol continues to serve as a robust, trusted set of standards.”

A new phase for carbon accounting
Tim’s arrival comes as the GHG Protocol enters a period of change.
The organisation has been expanding and updating its frameworks, while also strengthening its governance structure to support broader global use.
“The scale of our work and the pace of change across the reporting landscape bring with them a growing need for a dedicated CEO role,” says Geraldine Matchett, Chair of the GHG Protocol Steering Committee.
“This reflects a natural step in GHG Protocol’s institutional maturity and will enable the organisation to meet rising expectations while sustaining the integrity and independence of its standards. Tim fits the bill perfectly and is the right leader for this moment.”
The appointment also reflects how carbon accounting has moved from a back-office reporting exercise to a core business issue. Emissions data now influences compliance, capital allocation, procurement and climate strategy, which raises the stakes for how standards are designed and maintained.
“Looking ahead, the work of the protocol is becoming even more important,” Tim explains.
“Climate measurement is moving from voluntary to mandatory, so expectations are rising. This shift is fueled by the needs of investors and regulators who require accurate, verified, decision-useful information to manage risk, resilience, and the transition to a low-carbon economy.”
