In 1998, it became the first spirit house awarded ISO 14001 certification, which has subsequently renewed over three years.

Exceptional Heritage

Our exceptional heritage endows us with important responsibilities. The Maison Hennessy strives to lead by example, developing environmentally responsible initiatives and assuring our customers of the excellence of our production facilities and practices. The president of Hennessy has mandated the environmental policy which declares Hennessy commitment to the environment. Hennessy’s proactive approach has afforded marked success in water and energy reduction as well as waste recycling and management.

Energy

Indispensable to the development of our cognacs, energy is of paramount interest to Hennessy. It is our daily endeavor to reduce our energy consumption and employ new, clean and renewable energies. Hennessy first calculated its carbon footprint in 2002. We have since repeated and expanded this initiative to include energy assessments that have drastically reduced our energy consumption and greenhouse gas emissions: combustion optimization, in particular, has decreased gas usage at our distilleries by 20%. We have also been attentive to developing sustainable transportation: over 90% of our products are transported by sea or rail, and electric vehicles are employed for inter-warehouse transportation. In honor of Sustainable Development Week 2012, the house has eagerly focused on sustainable energy.

Sustainable Viticulture

Hennessy is involved in sustainable winemaking through the commitment of its wine-growing subsidiary SODEPA, having reduced inputs as per the requirements of the French 'Environmental Grenelle'. In 2011, Hennessy was named an exemplary farm under the 2018 Ecophyto Plan.

Water

By auditing our water requirements thoroughly and frequently through regular readings of more than 70 water meters, Hennessy has crafted a global policy to manage and reduce our water consumption. Renovations of our water distribution systems and the conversion of the cooling systems at our distilleries to closed circuits have reduced our distilleries’ water consumption by 90%. Thanks to recovery tanks, Hennessy collect and store storm water that satisfies in part the water requirements of our vineyards. These initiatives have enabled a 25% reduction in water consumption since 2007.

Effluent Treatment and waste valorization

All human activities produce waste, which must be subsequently treated to reduce its environmental impact. Hennessy analyzes all effluents so that they may be relayed to the most appropriate treatment facilities. Since the 1970s, in cognac, distillation residue (called “vinasses”) are treated via methanization, in partnership with REVICO, resulting in depolution by 98% and biogas production which generate the green energy that heats the city of Cognac's greenhouses and produces electricity through cogeneration. Our waste is recycled on average with more than 85% by material or energy recovery.

Eco-Design

Hennessy strives to minimize the environmental impact of its packaging base on life cycle analysis, while remaining attentive to the quality expectations of luxury goods. We evaluate the environmental impact of all proposed designs and encourage the use of recyclable, green materials.
