Greener energy, still great Guinness

When gas wells were drilled near our Guinness brewery in Douala, Cameroon, we joined forces with the gas company to bring our carbon emissions – and costs – down.

Since February 2013, the steam boilers that play such a crucial role in brewing Guinness at Douala have been fueled by natural gas following a six-month, £800,000 conversion project and a great partnership with our gas provider. Natural gas provides consistent energy while emitting significantly less CO2 than heavy fuel oil: in Douala we project that the switch from oil to gas, combined with efficiency improvements such as better insulation and heat recovery, will result in a 30% reduction in CO2 emissions.

The project began in 2012, when Guinness Cameroon agreed a contract with Rodeo Development Ltd to buy natural gas piped directly from their two new gas wells at Logbaba, Cameroon. By installing dual fuel burners, we were able to ensure that we could benefit from this new supply while retaining the flexibility and security we need to keep brewing great beer.

Baker Magunda, Managing Director of Guinness Cameroon, said: 'This new gas equipment will secure for our plant a constant and consistent energy supply, enabling us to achieve our business ambitions in a more efficient and sustainable manner.'

The project at Douala is one of dozens of energy initiatives undertaken in 2013 to help us meet our target of halving greenhouse gas emissions by 2015.
