What is Business Case?

Immediate benefits Other benefits
  • Communicate to stakeholders using carbon reporting industry best practice
  • Respond to corporate RFPs
  • Attract new customers by showing your commitments to carbon management
  • Improve energy management and reduce costs: what gets measured, gets managed.
  • Comply with carbon reporting legislation (in some countries) or prepare for upcoming legislation.
  • Improve profitability (studies show that companies who report on CO2 outperforming those who do not).


Why report on CO2 emissions?

The energy consumed to provide electricity, heating and cooling in hotel operations produces carbon emissions which contribute to the greenhouse effect and climate change.

At a corporate level, it is now common practice for hotel companies to disclose annual Greenhouse Gas (GHG) emissions. At the hotel property level, measuring and reporting on carbon footprint will become standard business practice as hotels seek competitive advantage and at the same time face government regulation.

Corporate hotel RFPs, including Global Business Travel Association's 2013 iteration of the Hotel RFP which includes additional sustainability questions such as the room night's carbon footprint and energy and water consumption.

Many of the large companies who purchase thousands of room nights and meeting rooms each year are also publicly traded companies with pressures to report and improve on environment issues. These companies are now asking for carbon footprint information from hotels. For example, Wal-Mart requests responses from suppliers on their sustainability index comprising of 15 questions.

Last year three key resources for organizing, measuring, and reporting sustainable eventswere released for event planners, and all of these include some mention of measuring carbon footprints (ISO 20122, APEX/ASTM Sustainable Events Standard, and the GRI Event Organizers Sector Supplement).

As metrics become more prevalent and relevant to the consumer, the transient guest's interest is also increasing.

Who is asking for carbon footprint information? Why it matters?
Investors Review of Environmental, Social, and Governance (ESG) performance.
Governments National and local regulations on carbon emissions and on the energy performance of buildings.
Corporate guests Report on the environmental impact information from their supply chain (including travel). Calculate their own organization's carbon footprint.
Groups Green meetings and sustainable events. Many city-wide events will survey and audit the hotel room block for a wide variety of sustainable practices.
Leisure guests Interest in carbon-neutral travel (i.e. offsetting their carbon footprint by paying into a program that reduces the same amount of GHG emissions elsewhere).
NGOs NGOs are putting pressure on businesses across all sectors to act responsibly. This include environmental performance.
Employees Studies have shown that employees prefer to join environmentally responsible businesses. Studies also show that employees who are engaged in their employer's 'green' initiatives are also more likely to stay with the company and be more productive.


HCMI is the industry-approved methodology to calculate carbon emissions for hotels.

Historically, each hotel company calculated carbon emissions in a different way. HCMI defines a common measurement method across the hotel industry globally that is supported by the industry and in line with best practice carbon footprint accounting.

Why HotelCO2?

HCMI is the industry-approved methodology to calculate carbon emissions for hotels.

HotelCO2.com makes the CO2 emissions reporting process a lot easier than if you had to look up up-to-date CO2 emission factors for your region and unit conversion factors and perform the various calculations on your own. We also provide additional (free) services such as benchmarking of your hotel's energy consumption and calculations of individual client's CO2 emissions from staying and holding meetings at your hotel.

Finally, we can provide assistance and training, as well as independent verification of your data.

Case Study: The Corporate Customers' View
A Major International Bank

The bank has been reporting energy and greenhouse gas performance data since 2003. The bank has been working to improve the quality of this information over time and in 2009 they developed internal Carbon Inventory Guidelines. Based on these Guidelines, in 2010 the bank calculated an expanded carbon inventory which includes greenhouse gas emission sources from its operations around the world.

The Carbon Inventory Guidelines currently relies on estimation of the carbon footprint of hotel rooms used on business travel by employees. With HCMI, hotels can now provide more accurate data to its customers.

As utility expense growth has exceeded the rate of inflation over the past few years, environmentally sustainable operations are among the most promising measures towards cost containment for hotels.

In New York City, Local Law 84 of 2009 requires all large buildings to annually measure and publicly disclose their energy consumption. Other cities and states are also starting to require energy reporting.
