Monitoring Techniques for Air Emissions

The American Petroleum Institute (API) discusses a process to compare methodologies used by member companies, national governmental bodies, and intergovernmental experts to develop a compendium of emission estimation methodologies. Read the report here.

The API has also developed SANGEA, an electronic greenhouse gas emissions calculation tool. Learn about it here.

The Canadian Association of Petroleum Producers has created a handbook of methodologies and example calculations for estimating volumes of gas released from various oil and gas well site equipment.

The Western Regional Air Partnership is a voluntary partnership of states, tribes, federal land managers, local air agencies and the US EPA whose purpose is to understand current and evolving regional air quality issues in the West. Their ongoing Oil and Gas Emission Inventory Project can be found here.
