Aiming for industry-leading performance


To continuously improve our environmental performance, Devon is proactive and results-oriented. We consider the potential impacts of our operations when planning activities and making decisions. We strive to comply with all applicable environmental laws and regulations, often going above and beyond what’s required. In the process, we incorporate technology, tools and best practices to help minimize or avoid effects on air, water, land and wildlife.

Devon seeks to work with contractors who share our commitment to environmental stewardship. Our contractors must adequately train their personnel to perform environmentally sound work and have programs to comply with applicable environmental laws, rules and regulations. Contractors as well as employees have responsibility to stop work to prevent spills or other environmental issues. Starting in 2023, contractors who perform work on Devon locations will complete annual assessments to help us evaluate their environmental, social and governance (ESG) performance in key areas.

Devon has established a track record of environmental performance improvements. To document progress on our long-standing priority to reduce our greenhouse gas (GHG) and methane emissions, we’ve responded to the CDP climate change survey for 18 consecutive years.


Transparency is important to our stakeholders and keeps us accountable for our results. Devon tracks specific metrics for GHG and methane emissions, flaring, spills, energy use, water use and others. We’ve consistently increased our disclosures in recent years and continue to share this information in this report and other public disclosures. For additional metrics and details on our environmental practices, please refer to our Climate Change Assessment Report and CDP responses.

EHS委员会由德文郡的业务单元d operations leaders, helps protect our social license to operate and advance our culture of environmental stewardship. The council sets environmental strategy and goals, tracks performance and evaluates the effectiveness of our environmental policies, protocols and practices. To continuously improve our performance, the group reviews environmental incidents and near misses, develops corrective actions as needed and shares best practices across Devon. Council members hold regular discussions with field production leaders to update them on rapidly evolving stakeholder expectations about climate change and environmental performance.


counc长期成功,德文郡的地位il reviews emerging EHS and ESG issues, as well as proposed laws and regulations and their potential financial, operational and reputational impact on the company.

The council drives industry-leading environmental performance by developing environmental goals that are approved by the board as part of our executive compensation formula. In 2021, we set goals to reduce flaring intensity, increase voluntary leak detection and repair (LDAR) surveys and lower our spill rate. The EHS team’s post-merger priorities included integrating environmental data and protocols from our two legacy companies, which it completed in the first quarter of 2022. Full implementation of our integrated environmental policies, protocols and practices is expected by year-end 2022.

Our 2022 corporate goals include a standalone emissions reduction goal with a 15% weighting and an ESG & community engagement goal with a 15% weighting—together accounting for 30% of the company’s performance scorecard. Our corporate goals and medium- and long-term goals challenge Devon to improve our performance and hold us accountable for producing oil and natural gas in an environmentally responsible way.
