UN Agencies Mark World Environment Day with Green Challenge Initiatives

In commemoration of this year’s World Environment Day, United Nations agencies in Lesotho came together under the “Green Challenge” initiative, demonstrating a collective commitment to environmental sustainability through practical and innovative climate-friendly actions.

The Green Challenge served as the flagship activity coordinated ahead of World Environment Day, encouraging UN agencies to take meaningful steps within their offices and daily operations to promote environmental responsibility and greener workplaces.

Participating agencies implemented a range of activities aimed at reducing their environmental footprint and inspiring sustainable behavior among staff members. These included carpooling and promoting shared transport to reduce emissions, tree planting initiatives, office clean-up campaigns, waste reduction and recycling efforts, as well as energy-saving practices such as switching off unused equipment and minimizing printing.

Several agencies also introduced innovative climate-friendly practices tailored to their operations, reinforcing the United Nations’ commitment to sustainability and environmental stewardship.

The Green Challenge culminated in a Brown Bag Session held on 5 June, where agencies gathered to share experiences, lessons learned, and practical initiatives implemented during the campaign. The session provided an opportunity for cross-agency learning and reflection on how the UN system can continue strengthening its environmental responsibility.

During the session, Neo Matsoso presented on the United Nations Development Programme (UNDP)’s environmental sustainability initiatives, highlighting efforts to green UNDP operations while advancing climate innovation and clean energy solutions in Lesotho. 

Among the initiatives shared was the UNLEASH UniPod programme in Lesotho, which supports youth-led innovation under the theme “Waste to Wealth.” Through the programme, young innovators are being empowered to transform waste management challenges into enterprise opportunities by developing prototypes and practical solutions that contribute to environmental sustainability and economic empowerment.

UNDP also highlighted its efforts to advance the clean energy transition through increased adoption of renewable energy and support for e-mobility solutions aimed at reducing carbon emissions and promoting sustainable transport options across the country.

Through the UNDP Moonshot Initiative, the first installation of a photovoltaic (PV) solar system at the UN House was successfully implemented and is already supplying clean energy to the premises. In addition, the adoption of electric vehicles (EVs) has contributed to reducing operational costs and greenhouse gas emissions associated with fossil fuel use.

Representing the World Food Programme (WFP), Kuruoane Phakoe presented on the Improving Adaptive Capacity of Vulnerable and Food-Insecure Populations in Lesotho (IACOV) project, which focuses on environmental protection and strengthening climate resilience in vulnerable communities.

Implemented mainly through the Government of Lesotho and WFP, the project supports the restoration of degraded ecosystems and rangelands to reduce soil erosion and land degradation. It also promotes water and soil conservation practices and supports climate-smart agriculture to help farmers adapt to droughts, erratic rainfall, and extreme weather conditions.

Albert Hlabana from the World Health Organization (WHO) also delivered a presentation highlighting the important link between health and the environment, emphasizing how environmental degradation and climate change continue to impact public health outcomes and community well-being.

Speaking during the session, the United Nations Resident Coordinator in Lesotho, Taija Korteinen, commended participating agencies for their enthusiasm and commitment to environmental action.

“The United Nations must lead by example,” she said, applauding agencies for taking practical steps to contribute to environmental sustainability both in the workplace and within their communities.

In recognition of their participation and commitment, the Resident Coordinator handed over certificates to agencies that took part in the Green Challenge.

The initiative reflects the UN in Lesotho’s continued commitment to promoting environmental sustainability and supporting global efforts to address climate change through collective action and everyday behavioral change.
