US natural gas utility Spire has committed to reducing its methane emissions by 53% by 2025 from 2005 levels.
The firm says this target will place it well ahead of international standards, which call for a commitment of a 26% to 28% reduction in greenhouse gas emissions nationwide.
Since 2005, Spire has reduced overall methane emissions by 39%.
In 2019, the company invested $287 million (£228m) to replace ageing infrastructure, resulting in a 21% leak reduction per 1,000 miles of distribution pipelines.
Steve Lindsey, Executive Vice President and Chief Operating Officer at Spire, said: “We know natural gas plays an important part in a sustainable energy future.
“That’s why we’re committed to moving our business forward in a way that protects the planet and supports communities for generations to come.
“As a natural gas utility, we will continue to find innovative ways to supply the energy people depend on while striving to become carbon-neutral by midcentury.”
