Around the world hotels will be switching off their lights for Earth Hour on Saturday and showcasing some great ways to raise awareness of global warming.
Switching out lights between 8.30 and 9.30pm on Saturday 25 March, the group is helping to demonstrate its firm commitment to respecting and protecting the environment in which it runs its business.
Through its participation NH aims not only to involve its hotels and employees across the world, but also its guests and wants to help increase society’s awareness of the importance of looking after our planet for future generations.
Through its ongoing commitment to the sustainable development of its operation, NH Hotel Group has completed various initiatives, enabling it to reduce its carbon footprint by more than 70% and its energy consumption by 29%, involving not only the company as a whole but also the suppliers with whom it works.
NH Hotel Group also has ISO 14001 certification in terms of environmental performance, and is the first global hotel chain to obtain ISO 50001 certification, the most important standard in energy management systems. The Group also supports renewable energies and 78% of the energy supplied to its hotels is green energy.
Earth Hour is an initiative led by the World Wide Fund for Nature (WWF), supported every year by hundreds of millions of people all over the world, joining their voices for the protection of the environment.
Since its creation in 2007, more than 7,000 cities have taken part in this initiative, enabling millions of people, companies and governments to join voices to demonstrate that a future based on clean energy is possible.
Meanwhile Hilton is encouraging its guests to participate in Earth Hour and win a trip to Iceland.

Maxime Verstraete, vice president of corporate responsibility, Hilton said, "We're incredibly proud that the Earth Hour movement was conceived at the Hilton Sydney nearly 10 years ago. Almost every year since, our team members have combined their passion for hospitality with fun and local activities supporting the movement. This year we're looking beyond our more than 4,900 properties, and inviting the world to be part of another exceptional Hilton experience. We hope our Travel with Purpose Contest will inspire others to learn more about climate change and energy conservation."
Thousands of Hilton properties around the world have participated in Earth Hour activities by finding creative ways to raise awareness about energy conservation and climate change - from arranging candle-lit dinners to hosting acoustic music performances for guests.
In 2015, Hilton and WWF announced  a multi-year commitment to collaborate on a water-stewardship strategy, expand sustainable seafood efforts, advance food waste efforts and accelerate the adoption of renewable energy across Hilton's portfolio.
Hilton views sustainability as a key part of its business. Water, energy, food, commodities, waste requirements and other factors significantly impact the economics of the company's business every day around the world. For this reason, preserving the environment is a business imperative and a cornerstone of Travel with Purpose, the company's corporate responsibility strategy to create shared value for Hilton Team Members, guests, business partners and communities.
Hilton's commitment to the environment is embedded across the business and supported by LightStay: an award-winning, global corporate responsibility performance measurement platform. LightStay was developed and implemented by Hilton to provide a one-stop solution for reporting environmental, operational and social impacts. It underpins multiple certifications including a system-wide certification against the International Standardization Organization (ISO) 50001 standard for Energy Management. Hilton was also the first hospitality company to certify commercial buildings under the U.S. Department of Energy's Superior Energy Performance program.
