The International Union for Conservation of Nature (IUCN) is a membership Union uniquely composed of both government and civil society organisations. It provides public, private and non-governmental organisations with the knowledge and tools that enable human progress, economic development and nature conservation to take place together.
Created in 1948, IUCN has evolved into the world’s largest and most diverse environmental network. It harnesses the experience, resources and reach of its 1,300 Member organisations and the input of some 10,000 experts. IUCN is the global authority on the status of the natural world and the measures needed to safeguard it. Our experts are organised into six commissions dedicated to species survival, environmental law, protected areas, social and economic policy, ecosystem management, and education and communication.
The ability to convene diverse stakeholders and provide the latest science, objective recommendations and on-the-ground expertise drives IUCN’s mission of informing and empowering conservation efforts worldwide. We provide a neutral forum in which governments, NGOs, scientists, businesses, local communities, indigenous peoples groups, faith-based organisations and others can work together to forge and implement solutions to environmental challenges.
By facilitating these solutions, IUCN provides governments and institutions at all levels with the impetus to achieve universal goals, including on biodiversity, climate change and sustainable development, which IUCN was instrumental in defining.
ISWA works to protect human health and the environment as well as to ensure sustainable resource management and provides the following scientific, economic and social instruments: International network, to share knowledge and experience in sustainable waste management and climate change mitigation
Expert working groups to advance knowledge and expertise
All kinds of professional events for the dissemination of information
Education and training courses tailored to the trainees needs including a qualification and certification programme
Professional publications including high quality research journals and magazines, up to date studies and developments from all over the world
Cooperation with all stakeholders in waste management, particularly the National Members of ISWA as well as with International Organisations and Institutions
Projects in developing economies to establish sustainable waste management practices
Raising the level of international awareness of the global waste emergency and finding funding instruments to combat this especially in developing economies
Ensuring international fora recognise the importance of good waste management for health, economic, social and overall environmental progress towards a more sustainable society

The United Nations Environment Programme (UN Environment) is the leading global environmental authority that sets the global environmental agenda, promotes the coherent implementation of the environmental dimension of sustainable development within the United Nations system, and serves as an authoritative advocate for the global environment.
Our mission is to provide leadership and encourage partnership in caring for the environment by inspiring, informing, and enabling nations and peoples to improve their quality of life without compromising that of future generations.
Headquartered in Nairobi, Kenya, we work through our divisions as well as our regional, liaison and out-posted offices and a growing network of collaborating centres of excellence. We also host several environmental conventions, secretariats and inter-agency coordinating bodies. UN Environment is led by our Executive Director Erik Solheim and Deputy Executive Director Ibrahim Thiaw.
We categorize our work into seven broad thematic areas: climate change, disasters and conflicts, ecosystem management, environmental governance, chemicals and waste, resource efficiency, and environment under review. In all of our work, we maintain our overarching commitment to sustainability.

Whilst first used by the Assyrians to heat bath water in 900BC, the exceptional potential of this simple yet highly sophisticated natural technology is only just starting to get the recognition it deserves, three thousand years on.
In today’s world, where job creation, economic growth, energy generation and food production must all be achieved at the same time as drastically cutting climate change emissions, few technologies have the ability to make such a huge contribution to all these areas worldwide.
Our goal is to demonstrate to all – and in particular the governments and municipalities developing the policies to meet their country’s energy needs, Climate Change commitments and UN Sustainable Development Goals – that they need to put biogas at the heart of those plans.
A naturally occurring biological process similar to that which takes place in the stomach of a cow, anaerobic digestion is the simple, natural breakdown of organic matter that occurs in the absence of oxygen into biogas (carbon dioxide and methane) and organic fertiliser called digestate. By recycling organic wastes such as food, farm and sewage wastes, energy crops, crop residues, grasses, seaweeds and algae, anaerobic digestion extracts the energy in the form of biogas and turns the rest into biofertiliser, replacing the need for energy intensive chemical fertilisers, and/or higher value bio-products and chemicals. Able to produce renewable energy constantly in the form of a gas, biogas can deliver energy in the form most needed – whether that’s baseload electricity and heat, or gas to fuel those areas that are harder to decarbonise, such as heating homes or fuelling heavy goods vehicles. With the flexibility of scale to design a plant run from the dung produced by two cows to one recycling 500,000mt of the first world’s food waste or sewage, biogas can support industries of any size the world over.
