Diversified Energy's 2022 Sustainability Report Details Emissions Reductions, Safety Wins, Community Investments

Company's differentiated asset stewardship model generates meaningful progress, shareholder value

BIRMINGHAM, AL / ACCESSWIRE / April 11, 2023 / Diversified Energy Company PLC (LSE:DEC) ("Diversified", "DEC" or the "Company") achieved key emissions reduction, safety, and community investment goals in 2022, the company stated in its 2022 Sustainability Report issued today.

The 4^th annual report, titled Decarbonizing While Delivering, presents Diversified's performance on material ESG targets through disciplined execution of the Company's differentiated asset stewardship model.

Deployment of new controls in 2022 to accurately detect and measure unwanted methane emissions, for example, led to a 25% decline in methane intensity relative to the 2020 baseline. This significant achievement positions the company ahead of its 30% target by 2026.

Additionally, Diversified's "OneDEC" safety and accountability program is rooted in fostering a culture of operational excellence by integrating people, processes and systems. Building on the success of OneDEC, 2022 saw a 50% incident rate decline. And the Company's recent launch of its community giving foundation resulted in $2.5 million in donations to support 140 organizations across its operating area.

Diversified remains a sustainability leader for existing producing and midstream assets, providing transparency through enhanced disclosures of greenhouse gas and air emissions, cyber security, state economic impact analysis across our operating footprint, and a variety of climate-related financial disclosures.

Commenting on the report, CEO Rusty Hutson, Jr. said:
"Diversified continues to demonstrate its leadership across a broad spectrum of environmental, social, and governance policies and disclosures. We proudly discuss our many accomplishments within our 2022 Sustainability Report. Stewardship underpins our differentiated business model and Smarter Asset Management activities to deeply embed sustainability in every aspect of our operations. Accordingly, we will play an increasingly critical role in a lower-carbon energy economy.

While environmental discipline is at the core of our business strategy, so too is our commitment to socio-economic development and community engagement. We are proud to have formalized our Community Giving and Engagement Program to support our commitment to contribute up to $2 million per year to this purpose. Building on past successes, we've positioned ourselves to deliver another year of substantial progress for our stakeholders, made possible by our focused team who are committed to safety and operational integrity."

Vice President of ESG & Sustainability, Teresa Odom, also commented:
"Diversified has built a track record of trust by delivering on our commitment to responsible operations and transparently reporting on the same. Our team of approximately 1,600 employees remain committed to driving and delivering meaningful progress through responsible stewardship, focused operations, and community engagement."
