Climate Lobbying Overview: Pemex appears to have negatively and actively engaged on climate change policies in Mexico, with some limited engagement in the US. The company states high-level support for climate policy in its messaging, but advocates for increasing oil and gas production in Mexico

Top-line Messaging on Climate Policy: Pemex has limited top-line messaging related to climate action. In its 2021 Sustainability Report, published in 2022, the company supported limiting global warming to 2°C or 1.5°C, and seemed to support the Mexican government’s commitment to the Global Methane Pledge at COP26. Pemex has not stated public positions on the need for climate change regulation, for example in its 2021 Sustainability Report, published in 2022, it disclosed engagement on Mexican climate policy, but did not state a position. The company consistently supported the UN Paris Agreement in its corporate communications, for example, supporting the 2°C target in its 2021 Sustainability Report published in 2022.

Engagement with Climate-Related Regulations: Pemex appears to be mostly negatively engaged with key climate policies in Mexico. In a November 2022 press release, Pemex stated support for Mexico’s methane reduction targets and the Global Methane Pledge. However, historically the company advocated to weaken methane regulation, for example in June 2020 in comments to policymakers the company advocated that only new facilities should be covered.

Pemex has predominantly engaged negatively on the Mexican Emissions Trading System (ETS), for example in its 2021 Sustainability Report published in 2022 Pemex suggested that it should allow the use of compensation credits from natural carbon capture projects in its operational phase. This mirrors the arguments stated in direct comments to policymakers on the Mexican ETS in 2018-19, for example, the company advocated to increase the percentage of emissions which can be compensated with credits from 10% to 20% in September 2019. It also stated in the same comment that the allocation of free emissions allowances should take into account the growth expectations of companies, although it did support including methane in the policy.

The company supports some elements of policy relating to the protection of carbon sinks and reservoirs but not others. In its 2021 Sustainability Report, published in 2022, Pemex supported strengthening the Mexican government’s certification and management program for protecting ecosystems. However, the company took a more negative position in June 2020 in comments to policymakers, not seeming to support the baseline and method used in the 2020-24 Environmental and Natural Resources Program.

Positioning on Energy Transition: Pemex supports a continued role for fossil fuels in the future Mexican energy mix, emphasizing the need for energy sovereignty. The CEO Octavio Romero consistently advocated for scaling up fossil fuel production to ensure Mexico’s energy security in 2022-23, for example, in January 2023 on Twitter. Furthermore, in June 2023 in a press release the CEO supported a continued role for fossil fuels, stating that the oil industry is “a pillar for the wellbeing of the people”. Furthermore, in comments to policymakers in March 2021, the company seemed to advocate for increasing oil production in Mexico.

Industry Association Governance: Pemex has not disclosed a list of its industry association memberships and indirect climate-related lobbying activities, nor has it published a full audit disclosure of its industry links. InfluenceMap detected that Pemex is a member of the Asociación Mexicana de Empresas de Hidrocarburos (AMEXHI), and a senior executive of subsidiary Pemex Deer Park is on the board of the American Fuel & Petrochemical Manufacturers Association which are engaging negatively with Mexican and US climate policy respectively.

In addition, Pemex is a listed company with more than 50% of its shares owned by the government of Mexico. State-owned enterprises likely retain channels of direct and private engagement with government officials that InfluenceMap is unable to assess, and therefore are not represented in Pemex's engagement intensity metric.

InfluenceMap collects and assesses evidence of corporate climate policy engagement on a weekly basis, depending on the availability of information from each specific data source (for more information, see our methodology). While this analysis flows through to the company’s scores each week, the summary above is updated periodically. This summary was last updated in Q3 2023.

Strength of Relationship

How to Read our Relationship Score Map

In this section, we depict graphically the relationships the corporation has with trade associations, federations, advocacy groups and other third parties who may be acting on their behalf to influence climate change policy. Each of the columns above represents one relationship the corporation appears to have with such a third party. In these columns, the top, dark section represents the strength of the relationship the corporation has with the influencer. For example if a corporation's senior executive also held a key role in the trade association, we would deem this to be a strong relationship and it would be on the far left of the chart above, with the weaker ones to the right. Click on these grey shaded upper sections for details of these relationships. The middle section contains a link to the organization score details of the influencer concerned, so you can see the details of its climate change policy influence. Click on the middle sections for for details of the trade associations. The lower section contains the organization score of that influencer, the lower the more negatively it is influencing climate policy.
