Dear Chevron Shareowner:

Support Proposal #6 Requesting Improved Transparency of Climate Lobbying Objectives

---

CalPERS is the largest state public pension fund in the United States with nearly $400 billion¹ in total assets under management, and a long-term owner of approximately 4.5 million shares in Chevron Corporation.

We are voting FOR proposal #6 (filed by BNP Paribas Asset Management) requesting for improved transparency of climate lobbying objectives. We urge shareowners to also vote for this important proposal at the company’s May 27^th, 2020 annual meeting of shareowners.

Vote FOR Improved Disclosure of Climate Lobbying Objectives

---

In our perspective, the company has failed to provide shareowners with the needed information to adequately assess their climate-related lobbying objectives - including how the company’s lobbying activities align with the goal of limiting average global warming to well below 2 degrees Celsius (the Paris Climate Agreement's goal).

Therefore, we believe that shareowners would benefit from improved disclosure of the company's climate lobbying objectives. The requested disclosure would help ensure that the company is transparent in its policy objectives, mitigate against reputational risks, and affirm that company funds were spent in a manner that is consistent with stated objectives.

Specifically, proposal #6 is requesting the Board of Directors conduct an evaluation and issue a report within the next year (at reasonable cost, omitting proprietary information) describing if, and how, Chevron' lobbying activities (direct and through trade associations) align with the goal of limiting average global warming to well below 2 degrees Celsius (the Paris Climate Agreement's goal). The report should also address the risks presented by any misaligned lobbying and the company's plans, if any, to mitigate these risks.

Vote FOR Shareowner Proposal #6

---

As a significant investor in Chevron, we encourage shareowners to support proposal #6. We believe that improved disclosure of the company’s climate lobbying objectives would allow shareowners to better assess the risks and benefits associated with such spending.

Thank you for your support.

Sincerely,
