The Household is committed to reducing its greenhouse gas emissions and first published its emissions data in 2007 along with a reduction target.

Carbon dioxide emissions arise as a result of the Household’s work in supporting Their Royal Highnesses as well as from the engagements undertaken by The Prince and The Duchess themselves. There are a wide range of sources such as heating and lighting offices, business travel between properties, staff commuting and official travel throughout the UK and around the world.

Please note: The Carbon Reports contain details of how the Household's carbon emissions are calculated and the independent assurance report produced by PricewaterhouseCoopers LLP (PwC).
