Information on methodology and/or basis

Wind energy plays an important role in reducing greenhouse emissions. And lubricant technology can help to make sure that today’s wind turbines run reliably and efficiently. 


Castrol has more than 30 years’ experience of working with the wind industry and today supplies lubricants to thousands of wind turbines. It is also the first lubricant supplier in the world to offer the wind industry certified carbon neutral lubricants. Optigear Synthetic CT 320 and Optigear Synthetic X 320 are both certified as carbon neutral throughout their life cycle, in accordance with the BSI PAS 2060 standard. This includes their production, transportation and eventual disposal at the end of their service life.


To achieve carbon neutral status, we offset residual emissions through BP Target Neutral, our carbon offsetting programme that helps support emission reduction projects around the world, such as forest conservation in Zambia and renewable energy in China, through the purchasing of carbon credits. These projects also help provide economic, social and environmental benefits to their local communities.
