The way food is produced and consumed today results in high rates of food loss and waste. This waste is responsible for an estimated 8-10 per cent of global greenhouse gas emissions. Food loss and waste has other impacts, such as wasted resources, loss of biodiversity and loss of natural ecosystems. All of this happens against a backdrop of rising food insecurity and malnutrition, with some 828 million people around the world suffering from hunger. UNEP promotes the massive potential to reduce the emissions of the sector while delivering benefits across the SDGs.

For the first time in history, the United Nations General Assembly has recognized that a clean, healthy and sustainable environment is a universal human right.

The ozone layer, a fragile shield of gas, protects the Earth from the harmful portion of the rays of the Sun, helping preserve life on our planet. As the treaty turns 35 on Ozone Day, we remember how the Montreal Protocol ended one of the biggest threats ever to face humanity as a whole: the depletion of the ozone layer. When the world found out that ozone-depleting gases used in aerosols and cooling were creating a hole in the sky, it came together and phased out these gases. Now the ozone layer is healing, allowing it to continue to shield humanity from the Sun’s ultraviolet radiation.

This year’s International Day of Clean Air for blue skies focuses on the transboundary nature of air pollution, stressing the need for collective accountability and action. It also highlights the need for immediate and strategic international and regional cooperation for more efficient implementation of mitigation policies and actions to tackle air pollution. We all breathe the same air, and one atmosphere protects and sustains us all. Pollution is a global problem that we must act together to combat. #TheAirWeShare

Brazil’s north-eastern semi-arid region, known as sertão, is a land rich in culture and enchanting landscapes, but the harsh climate and lack of water make it difficult to earn a living here.

Key to any project’s success is the focus on nature-based solutions and working with local people. IFAD is an international financial institution and a specialized agency of the United Nations dedicated to eradicating poverty and hunger in rural areas of developing countries.

This year’s campaign for World No Tobacco Day (31 May) aims to raise awareness on the environmental impact of tobacco – from cultivation, production, distribution and waste. It will give tobacco users one extra reason to quit.
