The ACR methodology for Conversion of High-Bleed Pneumatic Controllers in Oil & Natural Gas Systems is inactive and ineligible for crediting projects on ACR. The methodology relies on a performance standard additionality test that, per requirements in the ACR Standard, must be re-assessed at minimum every 5 years. The methodology may become active again based on the results of the performance standard review.

Methodology History
The methodology details requirements for oil & gas companies to reduce fugitive emissions of methane, a potent greenhouse gas, by retrofitting existing high-bleed pneumatic controllers in the U.S. with low-bleed options. According to the U.S. Environmental Protection Agency, high-bleed pneumatic controllers are among the largest sources of vented methane by equipment type in the domestic oil & natural gas industry.
