The savings can be achieved using existing energy saving technology some of which has been known for and been in use in a very small number of applications, but for more than 30 years.  The evaluation of potential car CO₂eq eliminations started in November 2019 and is ongoing. We therefore expect the 422.5 million cars equivalent figure to grow.  Calculations and the assumptions behind them are available for examination and agreement or denial on a case specific basis, which we would welcome, but it is not the point.  The point is that the Board of Directors of companies ought to have an environmental policy which encouraged participation from their own operators and suppliers and to which they gave priority.

The objective of this study is to estimate the potential energy savings which could be achieved through improving the efficiency of mechanical seal solutions utilised on plants around the globe.

This energy saving is expressed as a total of the number equivalent to an average car's annual CO₂ emissions.

A global calculation is done for each industry considered, estimating the number of pieces of rotating equipment on an individual site/plant, then the number of specific sealing applications, the total utilisation of those pieces of equipment, expressed in hours and the total number of plants globally.

The model consists of the following calculations subject to the nature of the application studied and the available researched equivalent CO₂ conversion factors for the fluids considered.

1. Calculation of steam turbine steam loss savings achievable via installation of Gas Lift Mechanical Sealing technology - assuming 90kg steam Loss per hour.
   
2. Calculation of the potential energy savings made by changing the sealing arrangement / API plan from least efficient to most efficient options, by way of reducing the need to heat up cool fluid injection from a continually fed external source.
