Air Quality
Air quality has been, for many years, an important focus of attention in Europe, resulting in legislative initiatives that affect the downstream oil industry through its operations and products.
Air quality has been, for many years, an important focus of attention in Europe, resulting in legislative initiatives that affect the downstream oil industry through its operations and products.
Concawe aims to participate in the work leading to new legislative initiatives and to carry out rigorous air quality analysis to contribute to the science, play an active stakeholder role and to inform its members. Concawe was very active in past EU scientific programmes including CAFE (Clean Air For Europe) and CAPE (Clean Air Program for Europe) and aims to play an important role in the Commission’s planned fitness check and likely subsequent revision of the current Ambient Air Quality Directive. Concawe has devoted substantial effort to developing its own air quality modelling tools which it uses to carry out these efforts and has submitted several contributions to the Stakeholders Expert Groups.
Concawe also completes research to identify and understand emerging air quality monitoring techniques, develops best practice documents for our members including methodologies for estimating refinery source air emissions, and contributes to the development of European standards through participation in the European Committee for Standardization (CEN) working groups.
Concawe has been conducting air quality research since its creation in 1963 and has published numerous technical reports on a wide array of topics.

Carbon, sulphur and hydrogen in oil refineries
In order to meet new fuels specifications, refineries need to reduce carbon and sulphur contents of petroleum fuels and therefore use more hydrogen. The net result is an increase in global CO2 emissions.
European air quality: changing priorities
Some insights from the second European Auto/Oil Programme.
The impact of Auto/Oil I and II on refinery costs and global CO2 emissions.
The EU Commission’s independent consultants recently published their results on the consequences of Auto/Oil II in terms of refinery costs. In addition CONCAWE has estimated the associated changes in global CO2 emissions.
Ambient particulate matter: sources and apportioning
Both current and predicted levels of PM emissions are subject to great uncertainty; hence the development of meaningful air quality strategies is complicated.

Much work on the development of reliable models still needs to be done to address concerns over particulate emissions.
