UNIT 4: ENVIRONMENT MANAGEMENT SYSTEMS<br />
ENVIRONMENT MANAGEMENT PROGRAMME FOR<br />
EMISSIONS CONTROL<br />
Emissions from hospitality facilities are mainly emissions from vehicles and from<br />
the burning of fossil fuels used for space and water heating and cooking.<br />
Regular maintenance checks should be conducted on boilers and generators.<br />
Filters and scrubbers should be fitted to exhaust fans, and be regularly cleaned<br />
and maintained. Local legislation on emission standards should be consulted<br />
before control devices are installed.<br />
The use of vehicles, boilers and generators that can operate on ethanol blends and<br />
bio diesel should also be considered.<br />
Some Facts About Bio-Fuels<br />
(From the Argonne National Laboratory, Canada, 1997)<br />
The use of 85%-ethanol-blended fuels has been shown to reduce greenhouse<br />
gas emissions by 30-36%. A 10%-ethanol blend results in a 25-30% reduction<br />
in carbon monoxide emissions (by promoting a more complete combustion of<br />
the fuel) and a 6-10% net reduction of CO2. In addition, as ethanol oxygenates<br />
the fuel, there is a roughly 7% decrease in exhaust VOCs emitted from lowlevel<br />
ethanol-blended fuels compared with fossil fuels. In high-level blends, the<br />
potential for exhaust VOC reduction is 30% or more.<br />
Examples of Good Practice<br />
At the WelcomeGroup Mughal Sheraton, Agra, India, carbon monoxide and<br />
sulphur dioxide emissions from boilers are purified through scrubbers before<br />
being released. All fossil-fuel-operated equipment is maintained in good<br />
working condition to minimise carbon dioxide emissions.<br />
The Sånga Säby Hotel, Study and Conference Centre, Svartsjö, Sweden, in<br />
association with the Swedish Ethanol Foundation, acquired the first rape methyl<br />
ester fuelled car in 1995. Today, all vehicles, tractors, boilers and some of the lawn<br />
mowers operate on rapeseed oil (the other lawn-mowers are powered by PV).<br />

ENVIRONMENT MANAGEMENT PROGRAMME FOR MANAGING<br />
INDOOR AIR QUALITY<br />
Indoor air pollutants include combustion gases such as carbon dioxide, nitrous<br />
oxides and hydrocarbons, tobacco smoke, VOCs, asbestos, ozone, dust and<br />
particles, CFCs and radon.<br />
The worldwide ban on the manufacture of CFCs came into effect in 1999. The<br />
phasing-out of CFCs and other ozone-depleting substances used in the hospitality<br />
business merits detailed consideration, and is discussed in the following subsection<br />
of this unit. Detailed information on the management of ozone-depleting<br />
substances in the hospitality industry can be found in the UNEP <strong>DTIE</strong> publication,<br />
entitled How the Hotel Industry can Help Protect the Ozone Layer, in 1998.<br />
Indoor environment quality depends on specific pollutants and their levels of<br />
concentration inside the building. Monitoring air quality will give the most accurate<br />
picture of the types and concentration of pollutants in the air. This requires<br />
specialist help and equipment that may not be available in-house.
