5 March: what is celebrated today
5 March brings together observances that invite us to think of the world as a fragile and profoundly interconnected system. Peace is not sustained only by agreements, the future is not built without responsible energy and knowledge of territory remains key to inhabiting it better. It is a day that speaks of balance: between security and cooperation, between progress and care, between technology and humanity.
International Day for Disarmament and Non-Proliferation Awareness
Since 2022, 5 March has been devoted to reflecting on disarmament and non-proliferation as pillars of global peace. The date focuses on the need to reduce weapons — especially weapons of mass destruction — and to strengthen a culture of security based on trust and international cooperation.
Beyond treaties and resolutions, this day highlights the role of education and civil society. Raising awareness means remembering that peace is not a passive state, but a daily construction requiring dialogue, shared responsibility and a long-term view of the consequences of armed violence.
World Energy Efficiency Day
World Energy Efficiency Day, celebrated since 1998, proposes a simple and transformative idea: live better while consuming less. It is not about giving up comfort, but about using energy intelligently, avoiding waste and choosing cleaner, more sustainable sources.
Energy efficiency connects everyday actions with the major environmental challenges. Every efficient light bulb, every kilowatt saved, every conscious decision contributes to the fight against climate change and to protecting the resources that sustain life.
European Surveyor and Geo-information Day
5 March also pays tribute to those who measure, interpret and represent the Earth: European Surveyor and Geo-information Day is celebrated in commemoration of the birth of Gerardus Mercator. It is a date that recalls the importance of knowing the territory in order to plan, build and protect.
Surveying and geo-information are quiet but essential tools. From urban planning to environmental management, this knowledge makes it possible to take more precise and responsible decisions, integrating science, technology and a vision of the future.
