Global Sustainable Finance Conference
Online
Wednesday 26th March 2025
13:00 (GMT)
Despite announcements at the COP29 meeting to triple climate finance for developing nations, the current annual flow of $850 billion remains significantly below the $2.4 trillion required by 2030 to meet climate targets. Developing countries, often the most vulnerable to climate impacts, face substantial barriers, including inadequate regulatory frameworks, perceived investment risks, and limited institutional knowledge. These challenges are compounded by insufficient private sector participation, underdeveloped carbon markets, and fragmented global collaboration, underscoring the need for actionable and inclusive solutions. The UNFCCC has highlighted the importance of governments and other key stakeholders to better understand the financial needs of developing countries and mobilising financial resources appropriately to support adaptation and mitigation efforts.
Financial institutions, whilst committed to supporting sustainable finance, are looking for solutions to create a win-win situation for all stakeholders. This involves addressing key challenges around governance, data management, reporting standards and compliance. Leveraging climate data through advanced ESG metrics and standardised reporting tools are also key to improving investment decision-making. Blended finance models, integrating public and private capital, have yielded promising results in terms of de-risking green investments and unlocking funding for high-impact projects.
This year’s conference will bring together policy makers, representatives from investment banks, central banks, analysts and other experts to analyse global and regional developments in sustainable finance and its future. We will examine unique advancements and persistent gaps in scaling green finance while evaluating ways to overcome them. Discussions will also delve into the role of digital technologies, including AI and blockchain, in enhancing accountability and efficiency. Carbon markets and pricing mechanisms will be discussed along with the role of cooperation on global and regional levels, robust monitoring systems, and KPIs to ensure accountability. By fostering collaboration, sharing best practices, and addressing structural barriers, the Global Climate Finance Conference 2025 aims to transform commitments into tangible progress, paving the way for a sustainable and equitable future.

International Day of Zero Waste
--
Sunday 30th March 2025
-
The International Day of Zero Waste aims to promote sustainable consumption and production patterns, support the societal shift towards circularity and raise awareness about how zero-waste initiatives contribute to the advancement of the 2030 Agenda for Sustainable Development.
The waste sector contributes significantly to the triple planetary crisis of climate change, biodiversity and nature loss, and pollution. Humanity generates an estimated 2.24 billion tons of municipal solid waste annually, of which only 55 per cent is managed in controlled facilities. Every year, around 931 million tons of food is lost or wasted and up to 14 million tons of plastic waste enters aquatic ecosystems.
Zero-waste initiatives can foster sound waste management and minimize and prevent waste, helping to address the triple planetary crisis, protect the environment, enhance food security and improve human health and well-being.

Aligning Financial Flows with Goals to Halt and Reverse Forest Loss: a ‘How To’ for Client Facing Teams
London (UK)
Thursday 24th April 2025 - Friday 25th April 2025
London (UK)
Cattle, soy, and palm oil are keystone commodities that underpin entire economies, support millions of rural livelihoods and permeate global food systems. However, they also drive habitat and biodiversity loss. To meet rising demand sustainably, we need resilient business models that decouple production from deforestation and certain land use change that contributes to emissions and habitat loss. Financial institutions, as the providers of capital to commodity companies, have the power to change the trajectory of deforestation and conversion rates. These emerging models can drive a new wave of agricultural productivity, reducing emissions and resource use while enhancing resilience and lowering costs.
Join TNC on April 24-25, 2025, at the Royal Society in London for a day and a half of private workshops to help you achieve deforestation and conversion-free finance. This closed door event will provide essential training to help the financial sector understand commodity supply chains, manage risk and achieve growth through empowered client-facing teams.

As a result of the amazing qualities of tuna, the fish are threatened by overwhelming demand. According to the latest data, among the seven principal tuna species, 33.3 percent of the stocks are estimated to be fished at biologically unsustainable levels
That is why in December 2016, the United Nations General Assembly voted to officially observe World Tuna Day.
The move underlines the importance of conservation management to ensure that we have systems in place to prevent tuna stocks from crashing. Many countries depend heavily on tuna resources for food security and nutrition, economic development, employment, government revenue, livelihoods, culture, and recreation.

This year’s World Migratory Bird Day (WMBD) campaign will highlight the need for a healthy coexistence between humans and birds. It will focus on creating and adapting environments that support migratory bird populations across all communities, from bustling cities to smaller towns and communities. There are actions everyone can take to protect our shared spaces with wildlife.
In 2025, WMBD will raise awareness about the many challenges migratory birds face due to human activities and expanding urban development. The campaign will advocate for strategic urban planning and conservation efforts that incorporate bird-friendly practices, making sure that our communities become havens for these remarkable travelers. The 2025 theme encourages action from all sectors, including national and local governments, businesses, community groups, and individuals worldwide.

This unique region, where argan trees have been cultivated for centuries combines agricultural biodiversity, resilient ecosystems and valuable cultural heritage. For that reason, it has gotten recognition and protection from various UN entities.
The United Nations Educational Scientific and Cultural Organization (UNESCO) designated in 1988 the endemic production area as the Arganeraie Biosphere Reserve. Also, all know-how concerning the argan tree was inscribed in 2014 on the UNESCO Representative List of the Intangible Cultural Heritage of Humanity.
Moreover, in December 2018, FAO recognized the Argan-based agro-sylvo-pastoral system within the area of Ait Souab – Ait Mansour in Morocco as a Globally Important Agricultural Heritage System.
And lastly, in 2021, the United Nations General Assembly proclaimed 10 May the International Day of Argania. The resolution, submitted by Morocco, was co-sponsored by 113 member states of the United Nations and adopted by consensus.

World Bee Day
--
Tuesday 20th May 2025
-
Bees and other pollinators, such as butterflies, bats and hummingbirds, are increasingly under threat from human activities.
Pollination is, however, a fundamental process for the survival of our ecosystems. Nearly 90% of the world’s wild flowering plant species depend, entirely, or at least in part, on animal pollination, along with more than 75% of the world’s food crops and 35% of global agricultural land. Not only do pollinators contribute directly to food security, but they are key to conserving biodiversity.
To raise awareness of the importance of pollinators, the threats they face and their contribution to sustainable development, the UN designated 20 May as World Bee Day.
The goal is to strengthen measures aimed at protecting bees and other pollinators, which would significantly contribute to solving problems related to the global food supply and eliminate hunger in developing countries.
We all depend on pollinators and it is, therefore, crucial to monitor their decline and halt the loss of biodiversity.

World Day to Combat Desertification and Drought
Tuesday 17th June 2025
-
Desertification, land degradation, and drought are among the most pressing environmental challenges of our time, with up to 40% of all land area worldwide already considered degraded.
Healthy land not only provides us with almost 95% of our food but so much more: it clothes and shelters us, provides jobs and livelihoods, and protects us from the worsening droughts, floods and wildfires.
At the same time, growing populations coupled with unsustainable production and consumption patterns fuel demand for natural resources, putting excessive pressure on land to the point of degradation. Desertification and drought are driving forced migration, putting tens of millions of people each year at risk of displacement.
Of the world’s 8 billion inhabitants, over one billion of young people under the age of 25 years live in developing countries, particularly in regions directly dependent on land and natural resources for sustenance. Creating job prospects for rural populations is a viable solution that gives young people access to eco-entrepreneurship opportunities and at the same time to scale up best practices.
This year, the theme of the Desertification and Drought Day “United for Land. Our Legacy. Our Future” spotlights the future of land stewardship — our most precious resource to ensure the stability and prosperity of billions of people around the world.

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.

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.

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.

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).

World Soil Day (WSD) is held annually on 5 December as a means to focus attention on the importance of healthy soil and to advocate for the sustainable management of soil resources.
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.

Global Sustainable Finance Conference
Online
Wednesday 26th March 2025
13:00 (GMT)
Despite announcements at the COP29 meeting to triple climate finance for developing nations, the current annual flow of $850 billion remains significantly below the $2.4 trillion required by 2030 to meet climate targets. Developing countries, often the most vulnerable to climate impacts, face substantial barriers, including inadequate regulatory frameworks, perceived investment risks, and limited institutional knowledge. These challenges are compounded by insufficient private sector participation, underdeveloped carbon markets, and fragmented global collaboration, underscoring the need for actionable and inclusive solutions. The UNFCCC has highlighted the importance of governments and other key stakeholders to better understand the financial needs of developing countries and mobilising financial resources appropriately to support adaptation and mitigation efforts.
Financial institutions, whilst committed to supporting sustainable finance, are looking for solutions to create a win-win situation for all stakeholders. This involves addressing key challenges around governance, data management, reporting standards and compliance. Leveraging climate data through advanced ESG metrics and standardised reporting tools are also key to improving investment decision-making. Blended finance models, integrating public and private capital, have yielded promising results in terms of de-risking green investments and unlocking funding for high-impact projects.
This year’s conference will bring together policy makers, representatives from investment banks, central banks, analysts and other experts to analyse global and regional developments in sustainable finance and its future. We will examine unique advancements and persistent gaps in scaling green finance while evaluating ways to overcome them. Discussions will also delve into the role of digital technologies, including AI and blockchain, in enhancing accountability and efficiency. Carbon markets and pricing mechanisms will be discussed along with the role of cooperation on global and regional levels, robust monitoring systems, and KPIs to ensure accountability. By fostering collaboration, sharing best practices, and addressing structural barriers, the Global Climate Finance Conference 2025 aims to transform commitments into tangible progress, paving the way for a sustainable and equitable future.

Sunday 30th March 2025
-
The International Day of Zero Waste aims to promote sustainable consumption and production patterns, support the societal shift towards circularity and raise awareness about how zero-waste initiatives contribute to the advancement of the 2030 Agenda for Sustainable Development.
The waste sector contributes significantly to the triple planetary crisis of climate change, biodiversity and nature loss, and pollution. Humanity generates an estimated 2.24 billion tons of municipal solid waste annually, of which only 55 per cent is managed in controlled facilities. Every year, around 931 million tons of food is lost or wasted and up to 14 million tons of plastic waste enters aquatic ecosystems.
Zero-waste initiatives can foster sound waste management and minimize and prevent waste, helping to address the triple planetary crisis, protect the environment, enhance food security and improve human health and well-being.

Aligning Financial Flows with Goals to Halt and Reverse Forest Loss: a ‘How To’ for Client Facing Teams
London (UK)
Thursday 24th April 2025 - Friday 25th April 2025
London (UK)
Cattle, soy, and palm oil are keystone commodities that underpin entire economies, support millions of rural livelihoods and permeate global food systems. However, they also drive habitat and biodiversity loss. To meet rising demand sustainably, we need resilient business models that decouple production from deforestation and certain land use change that contributes to emissions and habitat loss. Financial institutions, as the providers of capital to commodity companies, have the power to change the trajectory of deforestation and conversion rates. These emerging models can drive a new wave of agricultural productivity, reducing emissions and resource use while enhancing resilience and lowering costs.
Join TNC on April 24-25, 2025, at the Royal Society in London for a day and a half of private workshops to help you achieve deforestation and conversion-free finance. This closed door event will provide essential training to help the financial sector understand commodity supply chains, manage risk and achieve growth through empowered client-facing teams.

World Tuna Day
--
Friday 2nd May 2025
-
As a result of the amazing qualities of tuna, the fish are threatened by overwhelming demand. According to the latest data, among the seven principal tuna species, 33.3 percent of the stocks are estimated to be fished at biologically unsustainable levels
That is why in December 2016, the United Nations General Assembly voted to officially observe World Tuna Day.
The move underlines the importance of conservation management to ensure that we have systems in place to prevent tuna stocks from crashing. Many countries depend heavily on tuna resources for food security and nutrition, economic development, employment, government revenue, livelihoods, culture, and recreation.

World Bee Day
--
Tuesday 20th May 2025
-
Bees and other pollinators, such as butterflies, bats and hummingbirds, are increasingly under threat from human activities.
Pollination is, however, a fundamental process for the survival of our ecosystems. Nearly 90% of the world’s wild flowering plant species depend, entirely, or at least in part, on animal pollination, along with more than 75% of the world’s food crops and 35% of global agricultural land. Not only do pollinators contribute directly to food security, but they are key to conserving biodiversity.
To raise awareness of the importance of pollinators, the threats they face and their contribution to sustainable development, the UN designated 20 May as World Bee Day.
The goal is to strengthen measures aimed at protecting bees and other pollinators, which would significantly contribute to solving problems related to the global food supply and eliminate hunger in developing countries.
We all depend on pollinators and it is, therefore, crucial to monitor their decline and halt the loss of biodiversity.
International Day for Biological Diversity

World Day to Combat Desertification and Drought
Tuesday 17th June 2025
-
Desertification, land degradation, and drought are among the most pressing environmental challenges of our time, with up to 40% of all land area worldwide already considered degraded.
Healthy land not only provides us with almost 95% of our food but so much more: it clothes and shelters us, provides jobs and livelihoods, and protects us from the worsening droughts, floods and wildfires.
At the same time, growing populations coupled with unsustainable production and consumption patterns fuel demand for natural resources, putting excessive pressure on land to the point of degradation. Desertification and drought are driving forced migration, putting tens of millions of people each year at risk of displacement.
Of the world’s 8 billion inhabitants, over one billion of young people under the age of 25 years live in developing countries, particularly in regions directly dependent on land and natural resources for sustenance. Creating job prospects for rural populations is a viable solution that gives young people access to eco-entrepreneurship opportunities and at the same time to scale up best practices.
This year, the theme of the Desertification and Drought Day “United for Land. Our Legacy. Our Future” spotlights the future of land stewardship — our most precious resource to ensure the stability and prosperity of billions of people around the world.

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.
International Youth Day

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.
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).

World Soil Day (WSD) is held annually on 5 December as a means to focus attention on the importance of healthy soil and to advocate for the sustainable management of soil resources.
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.
