Pollution and Waste

The first UNEP Global Assessment of Air Pollution Legislation presents the findings of a study of air quality legislation in more than 194 countries. Using the Air Quality Guidelines developed by WHO, the report examines the legal measures for determining whether air quality standards are being met and what legal standards exist for failure to meet them. The Assessment provides recommendations to assist countries in strengthening air quality governance and serves as a resource for countries wishing to effectively address air pollution and contribute to the achievement of the SDGs.

UNEP celebrates the anniversary of 132 parties working together to disrupt the trade, raise public awareness, build institutional capacity, and create mercury-free products.

Every year, the toxic trail of economic growth – pollution and waste – results in the premature deaths of millions of people while doing untold damage to the planet. Plastic poses a big problem from source extraction to waste. Not only to the environment, but also to human beings and the achievement of the Sustainable Development Goals. Would you like to know how? Find out with this animation! UNEP supports strong laws and institutions for a healthy planet and healthy people.

The Global Commitment to the New Plastics Economy campaign is making progress but the world needs to ramp up actions to curb plastic pollution. Humanity dumps its own combined weight in plastics annually into ecosystems. That’s 300 million tonnes every year choking waterways and seas, clogging streets, harming wildlife, and causing damage to public health. To stem that tide, UNEP and partner lobbied private and public sector decisionmakers to commit to cultivating a circular economy around plastics, one in which plastics are made to last and to be reused.

Discarded electrical and electronic equipment (such as phones, laptops, fridges, sensors and TVs), known as e-waste, is a growing challenge, matching the growth of the information and communication technology (ICT) industry. There are currently more mobile cellular subscriptions on Earth than there are humans. E-waste contains substances that can be hazardous to human health and the environment if not dealt with properly – including mercury, cadmium and lead. Improper e-waste management can also contribute to global warming. The goal is a system in which all discarded products are collected and then the materials or components reintegrated into new products.

While national and local interventions are largely focused on protecting lives and economies during COVID-19, management of hazardous waste is also essential to minimize long-term risks to human and environmental health. A UNEP new publication - Waste Management during the COVID-19 Pandemic: from response to recovery - reviews current practices for managing waste from healthcare facilities, households and quarantine locations accommodating people with confirmed or suspected cases of COVID-19.

Helping mitigate the impacts of an oil spill in Mauritius

Often close to world shipping lanes, small island and coastal nations are at particular risk from oil spills. Reliant on the marine environment and its biodiversity for tourism, fishing and aquaculture, islanders face an existential threat when oil spills happen in their waters. This is why the environmental crisis unfolding in Mauritius brings into focus the international legal framework in place to provide support when ship-source environmental disasters strike.

UNESCO reports that Trash Hacks are small changes you can make that will help the planet in a big way. Becoming a Trash Hacker will help you to learn about waste, take action to tackle trash and inspire others to do the same. #TrashHack your life and reduce your impact. Be part of the solution.

Even though Coronavirus lockdowns around the globe have led to a dramatic 5% drop in greenhouse gas emissions, not all measures have had a positive impact on the environment. Our streets, beaches and ocean have been hit by a tidal wave of plastic waste including face masks, gloves, hand sanitizer bottles and food packaging. Global trade policies could play an important role in the fight against plastic pollution. Besides regulating the production and consumption of plastics, UNCTAD also urges governments and businesses to identify non-fossil fuel plastic substitutes.

A new set of Recommendations published with the participation of the UNWTO outline how the global tourism sector can continue its fight against plastic pollution, while effectively facing the public health and hygiene challenges of the COVID-19 pandemic. The recommendations illustrate how reducing the plastic footprint, increasing the engagement of suppliers, working closer with waste service providers, and ensuring transparency on the actions taken, can significantly contribute to the responsible recovery of the tourism sector.

Worldwide, 80% of the wastewater is released to the environment untreated. Wastewater is often seen as a burden rather than a valuable resource.
