Director General's Message

"Leading by example, UNOG has made sustainability a key operating principle. Through technological innovation, partnerships and a transformation of processes, we continuously make our activities more sustainable, resilient and cost-effective. With introduction of electronic processing in servicing, the PaperSmart business model in conference management, integration of solar energy, use of natural gas for heating and of lake water to cool the buildings, we continue to cut consumption of paper, electricity, water and fuel. Ensuring the long-term sustainability of our operations is also a central objective for the Strategic Heritage Plan for the Palais des Nations. Individual commitment and teamwork are critical."

"Every choice we make in our daily work has implications for future generations. We need to make those choices sustainable – together". 

Michael Møller, Director-General, UNOG

Reduction efforts




During the past years much has been done to decrease UNOG’s energy consumption and CO2 emissions. UNOG also pursues its actions in order to develop the use of renewable energy. The most significant initiatives and achievements are:

  • Cooling of the buildings with the water of the Leman Lake.
  • Fuel oil has been replaced by natural gas for winter heating.
  • Replacement of the lighting fixtures at the Palais des Nations with energy efficient ones.
  • Upgrade of the Building Management System (BMS) controlling ventilation, heating, air conditioning, and automatic lighting, to control 15,000 points. For instance, the lighting of some corridors and halls is now automatically switched off when not needed.
  • A few ventilation units have been changed with high efficiency units, equipped for heating recovery.
  • Temperature in air-conditioned meeting rooms kept at an average of 24°C (74°F) in summer when rooms are in use. All air-conditioners are turned off when rooms are not in use.
  • Thermostatic valves have been installed on all the heating radiators.
  • Replacement of the flushes of the toilets.
  • Recycling programme for waste is on-going.
  • Improvement of thermal insulation of skylights, conference rooms, halls and offices through the replacement of obsolete glazed structure (about 1000 windows) by a new double glazing system compliant with energy saving and security related standards.
  • Thermal insulation and water proofing system of roofs.
  • Installation of 3300 m2 of photovoltaic panels on the roofs of several buildings of the Palais des Nations, designed to produce annually 400,000 kWh.
  • Extension of the existing solar panels field increasing the capacity of production of sanitary hot water, in particular for the showers at the cyclists' disposal and the cafeteria.
  • Separation of storm water from sewage water to reduce pollution.
  • All electricity purchased by UNOG comes from renewable energy sources.
  • Lighting fixtures of the roads and parking of the Palais have been replaced by LED sources.
  • Construction of shelters for electrical cars equipped with photovoltaic panels and charging stations in car parks. The recharging of cars is free, in order to encourage staff members to use low emission vehicles.
  • Renewal of the "Certificat de qualité nature et économie" for Ariana Park by Fondation Nature & Economie.
  • Sheep are grazing the meadows of the Park Ariana in autumn every year, thereby cutting the grass in an ecologically sustainable manner and providing natural fertilizers.
  • Bees have produced UN honey for the first time in 2013. 

The following reductions in emissions were realized:

  • UNOG has cut electricity consumption by 32% (5,300,696 KWh less beetween 2000 and 2015)
  • UNOG has cut water consumption by 66 % (202,122 M3 less between 2000 and 2015)
  • UNOG has cut heating energy consumption by 39% (7,894 MwW less between 2000 and 2015)


  • Encouragement to travel by train, whenever a convenient solution exists, was implemented. 


  • Inauguration of the new Geneva Technology Centre (data centre), which dramatically lowers energy consumption in comparison with traditional solutions.
  • Upgrading of videoconference bridge.
  • Consolidation of server rooms.
  • Continued virtualization of servers, reducing the total number of physical machines.
  • Greening the Desktop environment - Monitor and reduce energy consumption of computers managed by ICTS, taking full advantage of configuration features.

Print shop


UNOG's printing and distribution facility maintains ISO 14001:2004 certification of its Environmental Management System (EMS).


Translation services


UNOG increased off-site translation of documents and eliminated travel of freelance translators to Geneva.


Greener postal services contract


Contracts for the delivery of mail and express mail include for the first time a number of sustainable requirements that were developed in close cooperation with UNEP:

  • The contractors will have to provide an annual report detailing sustainable policies and environmental principles adopted by the company to reduce the environmental impact of its operations and in particular its CO2 emissions (“carbon footprint”).
  • Packaging and labeling material for express mail made of environment friendly materials.
  • Contractors use hybrid or electrical vehicles. Measures are undertaken to plan efficient itineraries with the aim to reduce driving times and fuel consumption.
  • Buildings and sorting machines used by contractors are environmentally sustainable (passive / energy efficient buildings and energy efficient sorting machines).
  • Shipments with no impact on the climate (carbon-neutral mailing) are available.

Green catering contract


UNOG successfully completed the retendering of the catering contract. The following changes were implemented:

  • Organic food on the cold buffet.
  • “Natura” menus composed of local, organic and fare trade food; Installation of a composter to recycle food waste.
  • Partnership with a local association for redistribution of unsold meals.
  • Eco-contract with the city of Geneva for the reduction of waste and electricity.
  • Price differential for hot drinks served in mugs.
  • Fare trade coffee and teas.
  • Exclusive use of biodegradable cleaning products.

Green commuting


Over the past several years, UNOG has been promoting green commuting. In this light, UNOG established a Blog on green commuting, has made available the map of cycling routes in the Canton, took part in the car sharing initiative “covoiturage-Leman”, and with UNHCR, ITU and WIPO, proposed free bicycle rental at the Place des Nations. In 2016, UNOG took part in the European Cycling Day, created a Working Group on mobility and green commuting within the Palais des Nations, integrated information from the Geneva public transport authority into landing page of the UNOG Intranet, offered staff members the opportunity to test electric bicycles on-site, hosted a bicycle mechanic on-site and created some 70 additional bicycle parking spaces.


Bike to work initiative


This Swiss initiative, launched in 2006 to promote cycling in the corporate world, was particularly successful in 2016: 1,773 companies registered more than 53,922 participants.

A record number of UN staff in Geneva signed up for the 2016 edition of "Bike to Work". 90 teams registered for a total of 360 participants who traveled 88,898 km, equivalent to almost five times the distance Geneva-New Zealand, in 2 months.



There are currently no budgetary provisions for purchasing carbon offsets.
