Hotelympia visitors are being urged to sign a pledge to use more energy-efficient equipment.
The Responsible Hospitality Partnership wants companies heading to the ExCeL event, which starts 26 February, to substitute an existing technology for one that is more environmentally friendly.
The online pledge initiative has been developed by RHP and supported by Beacon Purchasing and a number of their key suppliers, who provide the sustainable technology and products that the pledges are based on.
Those who sign the online pledge and enter some basic information will earn a free instant estimate of cost and carbon savings. They will also receive a certificate of their pledge and some additional tips on resource-efficient technologies.
"People are often sceptical of low-cost technologies," said Responsible Hospitality Partnership director Jane Carlton Smith.
"But everyone is feeling the need to save money and they have forgotten that they can save money very easily with low-cost investments in energy-saving technology."
Carlton Smith highlighted Hippo water savers, which fit in to toilet cisterns and cost less than £1 each.
"Energy-efficient light bulbs are also relatively inexpensive but savings can be astronomical," Carlton Smith said.
The Responsible Hospitality Partnership is also behind Hotelympia's Waste Works programme, which will feature free presentations and workshops to help companies reduce waste and save money.
Visitors to ExCeL will see four giant sculptures at each of the four entrances to the site. The sculptures will be made from cans, cooking pans and other junk material.
