What is differentiated natural gas?
Differentiated natural gas, also referred to as certified gas or responsibly sourced gas, is natural gas produced in a manner that accurately quantifies and minimizes methane emissions and has undergone a third-party review confirming compliance with relevant standards.
Montrose’s Sustainability and Climate Advisory team provides strategic support to assist companies in addressing their toughest environmental and broader sustainability challenges, including transitioning to a low-carbon economy while continuing to thrive in the oil and gas marketplace.
