A Buildings Energy Management System (BEMS) has led to improved energy efficiency by monitoring the use of steam, water and compressed air. New buildings on the site have been designed to minimise energy use.

The natural gas-fired Combined Heat and Power (CHP) plant has also helped to achieve dramatic cuts in emissions of carbon dioxide, nitrogen oxides and sulphur dioxide. By generating a large percentage of it's own power, Pfizer does not require imported electricity from power stations which are often less efficient than the CHP plants and create more pollution.

Emissions are reduced by using CHP for electricity and heating.
