If going green is important to your company then you should know that if you’re booking a colleague or visitors into a Marriott hotel than you’ll also have the opportunity to offset the carbon emissions created during their stay. Part of the Marriott Spirit to Preserve programme, the initiative enables guests to go online and offset emissions, which have been calculated by the Marriott team as costing $1 per room, per night. The hotel measured its electricity and gas usage in guest rooms and public spaces across nearly 1,000 hotels worldwide, as well their headquarters and regional buildings to determine the cost of off-setting. A minimum of $10 is required and the transaction is handled separately from the room charges as the project is managed by justgive.org and donations will be used for the Juma project, a programme to protect the rainforest which is part of the Amazonas Sustainable Foundation in Brazil (ASFB).
