Air emissions

Advanced technology and tougher regulations have helped improve air quality over the past 20 years. But this must continue as global energy demand grows.

Our operations

Pernis refinery, Netherlands

We have been working to limit the emissions of local pollutants – such as nitrogen oxides (NOx), sulphur dioxide (SO₂) and volatile organic compounds (VOCs) – from our operations by investing in advanced technologies and improving our processes.

Cleaner fuels

We were one of the first companies in the early 1990s to produce ultra-low sulphur diesel on a commercial scale. We invested more than $1 billion at our refineries over the past decade to produce lower sulphur fuels. The sulphur levels of the fuels we sell vary, depending on what is available from local refineries. These  variations  will narrow as more governments in developing countries move toward lowering fuel sulphur specifications. We continue to work with governments to promote lower sulphur fuels and the modern engines needed to benefit from them.
