9th American Forest Congress
Washington D.C (United States)
Tuesday 15th July 2025 - Friday 18th July 2025
Washington D.C (United States)
The American Forest Congress is a proud tradition that has influenced the direction of forest conservation and management in America for more than a century. Since the first American Forest Congress in 1882 to the most recent in 2022, these seminal events have led directly to major outcomes in the forestry sector, including the creation of the U.S. Forest Service, the establishment of the eastern National Forests, new community-based and collaborative approaches to forestry, and efforts to advance the leadership of women within the forest community.
The 9th American Forest Congress will build on this legacy, providing forestry professionals and leaders an opportunity to gather with over 500 of their peers for three days to collaborate and identify transformative actions for the next century of forest stewardship.

International Day for the Conservation of the Mangrove Ecosystem
--
Saturday 26th July 2025
-
The International Day for the Conservation of the Mangrove Ecosystem, adopted by the General Conference of UNESCO in 2015 and celebrated each year on 26 July, aims to raise awareness of the importance of mangrove ecosystems as “a unique, special and vulnerable ecosystem” and to promote solutions for their sustainable management, conservation and uses.
Mangroves are rare, spectacular and prolific ecosystems on the boundary between land and sea. These extra ordinary ecosystems contribute to the wellbeing, food security, and protection of coastal communities worldwide. They support a rich biodiversity and provide a valuable nursery habitat for fish and crustaceans. Mangroves also act as a form of natural coastal defense against storm surges, tsunamis, rising sea levels and erosion. Their soils are highly effective carbon sinks, sequestering vast amounts of carbon.
Yet mangroves are disappearing three to five times faster than overall global forest losses, with serious ecological and socio-economic impacts. Current estimates indicate that mangrove coverage has been divided by two in the past 40 years.

This date, adopted in December 1994 by UN General Assembly resolution 49/214, marks the date of the first meeting of the UN Working Group on Indigenous Populations of the Sub-Commission on the Promotion and Protection of Human Rights held in Geneva in 1982.
Violations of the rights of the world’s Indigenous Peoples have become a persistent problem, sometimes because of a historical burden from their colonization backgrounds and others because of the contrast with a constantly changing society. In response to this problem, let’s remember every August 9 that Indigenous Peoples have the right to make their own decisions and carry them out meaningfully and culturally appropriate to them.

International Youth Day
--
Tuesday 12th August 2025
-
International Youth Day is commemorated every year on 12 August, bringing youth issues to the attention of the international community and celebrating the potential of youth as partners in today’s global society.
The idea for International Youth Day was proposed in 1991 by the young people who were gathered in Vienna, Austria, for the first session of the World Youth Forum of the United Nations System. The Forum recommended that an International Youth Day be declared, especially for fund-raising and promotional purposes, to support the United Nations Youth Fund in partnership with youth organizations.

Saturday 23rd August 2025 - Friday 29th August 2025
Rio de Janeiro (Brazil)
Rio Climate Action Week (RCAW) is an independent initiative, in partnership with the Mayor of Rio de Janeiro and London Climate Action Week. It is the latest edition of a series of city-based climate action weeks – which include Auckland, Baku, Bangkok, Dublin, Prague, Shanghai and Sydney – inspired by the unique model pioneered by London Climate Action Week from 2019 onwards.
RCAW is closely tied to the UNFCCC process of climate diplomacy and its implementation-focused action agenda. It owes its origins to a desire to promote closer cooperation between the COP29 and COP30 Presidencies at a pivotal time for international climate change policy and action.
Rio Climate Action Week is a prominent city-based response to the Brazilian COP30 Presidency’s call for “mutirão” – collective effort.
RCAW and the climate action weeks are Mutirão in Action: demonstrating both bottom-up and top-down action to mitigate and adapt to the impacts of climate change and build resilience across societies and communities.

International Day for the Preservation of the Ozone Layer
--
Tuesday 16th September 2025
-
In 1994, the United Nations General Assembly proclaimed 16 September the International Day for the Preservation of the Ozone Layer, commemorating the date of the signing, in 1987, of the Montreal Protocol on Substances that Deplete the Ozone Layer (resolution 49/114).
The principal aim of the Montreal Protocol is to protect the ozone layer by taking measures to control total global production and consumption of substances that deplete it, with the ultimate objective of their elimination on the basis of developments in scientific knowledge and technological information. It is structured around several groups of ozone-depleting substances. The groups of chemicals are classified according to the chemical family and are listed in annexes to the Montreal Protocol text. The Protocol requires the control of nearly 100 chemicals, in several categories. For each group or annex of chemicals, the Treaty sets out a timetable for the phase-out of production and consumption of those substances, with the aim of eventually eliminating them completely.

International Day of Awareness of Food Loss and Waste
--
Monday 29th September 2025
-
Food loss and waste undermine the sustainability of our food systems. When food is lost or wasted, all the resources that were used to produce this food – including water, land, energy, labour and capital – go to waste. In addition, the disposal of food loss and waste in landfills, leads to greenhouse gas emissions, contributing to climate change. Food loss and waste can also negatively impact food security and food availability, and contribute to increasing the cost of food.
Our food systems cannot be resilient if they are not sustainable, hence the need to focus on the adoption of integrated approaches designed to reduce food loss and waste. Actions are required globally and locally to maximise the use of the food we produce. The introduction of technologies, innovative solutions (including e-commerce platforms for marketing, retractable mobile food processing systems), new ways of working and good practices to manage food quality and reduce food loss and waste are key to implementing this transformative change.

International Day for Preventing the Exploitation of the Environment in War and Armed Conflict
--
Thursday 6th November 2025
-
The United Nations Environment Programme (UNEP) has found that over the last 60 years, at least 40 percent of all internal conflicts have been linked to the exploitation of natural resources, whether high-value resources such as timber, diamonds, gold and oil, or scarce resources such as fertile land and water. Conflicts involving natural resources have also been found to be twice as likely to relapse.
The United Nations attaches great importance to ensuring that action on the environment is part of conflict prevention, peacekeeping and peacebuilding strategies, because there can be no durable peace if the natural resources that sustain livelihoods and ecosystems are destroyed.
On 5 November 2001, the UN General Assembly declared 6 November of each year as the International Day for Preventing the Exploitation of the Environment in War and Armed Conflict (A/RES/56/4).

An international day to celebrate soil was recommended by the International Union of Soil Sciences (IUSS) in 2002. Under the leadership of the Kingdom of Thailand and within the framework of the Global Soil Partnership, FAO has supported the formal establishment of WSD as a global awareness raising platform. The FAO Conference unanimously endorsed World Soil Day in June 2013 and requested its official adoption at the 68th UN General Assembly. In December 2013, the UN General Assembly responded by designating 5 December 2014 as the first official World Soil Day.

International Day for the Conservation of the Mangrove Ecosystem
--
Saturday 26th July 2025
-
The International Day for the Conservation of the Mangrove Ecosystem, adopted by the General Conference of UNESCO in 2015 and celebrated each year on 26 July, aims to raise awareness of the importance of mangrove ecosystems as “a unique, special and vulnerable ecosystem” and to promote solutions for their sustainable management, conservation and uses.
Mangroves are rare, spectacular and prolific ecosystems on the boundary between land and sea. These extra ordinary ecosystems contribute to the wellbeing, food security, and protection of coastal communities worldwide. They support a rich biodiversity and provide a valuable nursery habitat for fish and crustaceans. Mangroves also act as a form of natural coastal defense against storm surges, tsunamis, rising sea levels and erosion. Their soils are highly effective carbon sinks, sequestering vast amounts of carbon.
Yet mangroves are disappearing three to five times faster than overall global forest losses, with serious ecological and socio-economic impacts. Current estimates indicate that mangrove coverage has been divided by two in the past 40 years.

International Day of the World’s Indigenous Peoples
--
Saturday 9th August 2025
-
In order to raise awareness of the needs of these population groups, every 9 August commemorates the International Day of the World’s Indigenous Peoples. This date, adopted in December 1994 by UN General Assembly resolution 49/214, marks the date of the first meeting of the UN Working Group on Indigenous Populations of the Sub-Commission on the Promotion and Protection of Human Rights held in Geneva in 1982.
Violations of the rights of the world’s Indigenous Peoples have become a persistent problem, sometimes because of a historical burden from their colonization backgrounds and others because of the contrast with a constantly changing society. In response to this problem, let’s remember every August 9 that Indigenous Peoples have the right to make their own decisions and carry them out meaningfully and culturally appropriate to them.

Rio Climate Action Week (RCAW) is an independent initiative, in partnership with the Mayor of Rio de Janeiro and London Climate Action Week. It is the latest edition of a series of city-based climate action weeks – which include Auckland, Baku, Bangkok, Dublin, Prague, Shanghai and Sydney – inspired by the unique model pioneered by London Climate Action Week from 2019 onwards.
RCAW is closely tied to the UNFCCC process of climate diplomacy and its implementation-focused action agenda. It owes its origins to a desire to promote closer cooperation between the COP29 and COP30 Presidencies at a pivotal time for international climate change policy and action.
Rio Climate Action Week is a prominent city-based response to the Brazilian COP30 Presidency’s call for “mutirão” – collective effort.
RCAW and the climate action weeks are Mutirão in Action: demonstrating both bottom-up and top-down action to mitigate and adapt to the impacts of climate change and build resilience across societies and communities.
International Day for the Preservation of the Ozone Layer
--
Tuesday 16th September 2025
-
In 1994, the United Nations General Assembly proclaimed 16 September the International Day for the Preservation of the Ozone Layer, commemorating the date of the signing, in 1987, of the Montreal Protocol on Substances that Deplete the Ozone Layer (resolution 49/114).
The principal aim of the Montreal Protocol is to protect the ozone layer by taking measures to control total global production and consumption of substances that deplete it, with the ultimate objective of their elimination on the basis of developments in scientific knowledge and technological information. It is structured around several groups of ozone-depleting substances. The groups of chemicals are classified according to the chemical family and are listed in annexes to the Montreal Protocol text. The Protocol requires the control of nearly 100 chemicals, in several categories. For each group or annex of chemicals, the Treaty sets out a timetable for the phase-out of production and consumption of those substances, with the aim of eventually eliminating them completely.

International Day of Awareness of Food Loss and Waste
--
Monday 29th September 2025
-
Food loss and waste undermine the sustainability of our food systems. When food is lost or wasted, all the resources that were used to produce this food – including water, land, energy, labour and capital – go to waste. In addition, the disposal of food loss and waste in landfills, leads to greenhouse gas emissions, contributing to climate change. Food loss and waste can also negatively impact food security and food availability, and contribute to increasing the cost of food.
Our food systems cannot be resilient if they are not sustainable, hence the need to focus on the adoption of integrated approaches designed to reduce food loss and waste. Actions are required globally and locally to maximise the use of the food we produce. The introduction of technologies, innovative solutions (including e-commerce platforms for marketing, retractable mobile food processing systems), new ways of working and good practices to manage food quality and reduce food loss and waste are key to implementing this transformative change.

International Day for Preventing the Exploitation of the Environment in War and Armed Conflict
--
Thursday 6th November 2025
-
The United Nations Environment Programme (UNEP) has found that over the last 60 years, at least 40 percent of all internal conflicts have been linked to the exploitation of natural resources, whether high-value resources such as timber, diamonds, gold and oil, or scarce resources such as fertile land and water. Conflicts involving natural resources have also been found to be twice as likely to relapse.
The United Nations attaches great importance to ensuring that action on the environment is part of conflict prevention, peacekeeping and peacebuilding strategies, because there can be no durable peace if the natural resources that sustain livelihoods and ecosystems are destroyed.
On 5 November 2001, the UN General Assembly declared 6 November of each year as the International Day for Preventing the Exploitation of the Environment in War and Armed Conflict (A/RES/56/4).
