Reckitt Benckiser has hit its 2020 carbon reduction targets eight years early, slashing greenhouse gas emissions per dose by 21% since 2007.

The Cillit Bang maker said brand innovation and operational efficiencies helped it achieve its target of slashing emissions by a fifth.

Packaging innovations included launching Nurofen and Gaviscon Advance in a double concentration, reducing emissions because they use less packaging and transport for each dose.

Last year Air Wick launched an innovative aerosol product using compressed air instead of butane, preventing the use of 20,000 tonnes of carbon dioxide emissions during the year.

The company also invested in its Nowy Dwór Mazowiecki manufacturing site in Poland last year, installing a combined heat and power plant that saved almost a quarter of the factory’s CO2 emissions.

Reckitt’s new sustainability Report also revealed that it had planted 5.4 million trees since 2006 as part of Trees For Change, making its manufacturing sites carbon neutral.

“Achieving our 2020 carbon target is testament to the innovation that drives the company,” said chief executive Rakesh Kapoor.

“It demonstrates our commitment to sustainability, which is embedded in our new strategy, vision and purpose announced in February 2012.”
