Cabubble Environmental Policy (16 May 2011)
GHG Emissions Estimates
GHG (greenhouse gas) emission estimates reported by Cabubble are expressed as carbon dioxide equivalents of both direct and indirect emissions. Carbon dioxide equivalent emissions include the effects of not only carbon dioxide (CO2) but also methane (CH4) and nitrous oxide (N2O) converted using Global Warming Potential (GWP) factors.
We believe that including both direct and indirect emissions as well as carbon dioxide equivalents of other greenhouse gases is the most thorough way of quantifying the environmental impact of travel in a convenient comparable measure.
All GHG emissions estimates shown by Cabubble are per vehicle, not per passenger, and are expressed in units of kilograms of carbon dioxide equivalent. There are many factors that determine emissions caused by road travel; amongst others these include vehicle age, condition, make and model, as well as traffic and weather conditions, routes taken, vehicle occupancy and loading, speed and general driving style. Emissions estimates provided by Cabubble must therefore be treated as an approximation of all possible contributing factors, and these estimates may differ from those obtained from other sources.
To ensure the most authoritative data and up-to-date methodology are used, our emissions calculations are based on October 2010 Defra guidelines. For further information, visit archive.defra.gov.uk/environment/business/reporting/conversion-factors.htm.
As a responsible participant in the UK leisure and business travel sectors, Cabubble Limited is run as efficiently as possible to minimise its own environmental impact.
Our highly automated systems allow us to maximise the use of electronic document formats and run a paperless office, while extensive use of video/voice conferencing minimises our own need for business travel. In addition, where possible we employ technologies that offer more power-efficient use of hardware, such as server virtualisation.
