Why take this course?

Air pollution impacts our health, environment and economy. The World Health Organization estimates that air pollution causes 7 million deaths every year. Air pollution also causes acidification and eutrophication of ecosystems and leads to global crop losses. In addition, air pollutants can also further exacerbate climate change, and a warmer climate, in turn, also affects air quality and impacts of air pollution.

To improve air quality, UNECE member States have been working successfully since 1979 to reduce air pollution in the region through the Convention on Long-range Transboundary Air Pollution.

This self-paced online course aims to raise awareness about air pollution and its effects, ways to prevent and reduce harmful emissions and the Convention and its protocols as an international framework for cooperation on cleaner air.

Why take this course?

Air pollution impacts our health, environment and economy. Air pollutants come from multiple sources, such as traffic, industry and agriculture, and are transported over large distances and across borders. It is therefore paramount that we take action together — across sectors and national boundaries.

UNECE member States have been working successfully for cleaner air in the region since 1979 through the Convention on Long-range Transboundary Air Pollution.

A basic obligation under the Convention is to report emission inventories. An emission inventory quantifies air pollutants and/or greenhouse gases emitted into the atmosphere in a defined geographical area and time span. Inventories are used to study trends in major air pollution sources and evaluate the impact of air pollution abatement measures. For example, Governments can use emission data to develop sustainable national and local policies, evaluate their effectiveness and impact on populations and ecosystems, demonstrate compliance with emission reduction targets, and provide information to the public.

This self-paced e-course aims to explain the importance of emission inventories for clean air policy development, the requirements for emission inventory reporting and methods for emission estimation.

Shifting Towards a Low Carbon Economy through Sustainable and Resilient Infrastructure

25 February 2022

News

The Government of Rwanda, UNEP and UNITAR partnered up to deliver a training on sustainable and resilient infrastructure to 29 participants from 5 African countries.

 

Read on to find out how capacity building is shaping up the transition to a more sustainable future,  supported by resilient and sustainable infrastructure.

Infrastructure underpins economic growth and enables access to basic services and transformative economic opportunities. However, if infrastructure development is not properly done, it can have negative consequences for people, the economy, the climate, and nature. To help unpack this complex topic and shed light on its importance, the Government of Rwanda, the United Nations Environment Programme (UNEP) and the United Nations Institute for Training and Research (UNITAR) partnered up to organize the first edition of the “Environmental Leadership Programme on Sustainable and Resilient Infrastructure” training.

The fully online training took place between 30th November 2021 and 8th December 2021 and aimed at enhancing capacity and improving the knowledge of policy makers in Rwanda, Uganda, Ethiopia, Kenya and Zambia on the importance and role that well-planned, sustainable, and resilient infrastructure plays in meeting the Sustainable Development Goals (SDGs). In total, 29 participants from the 5 African countries, representing various governmental institutions involved in infrastructure development and planning in their respective countries, took part in the training.

The training focused on various areas of infrastructure, ranging from international good practice principles for sustainable infrastructure; green finance; nature-based infrastructure solutions; sustainable and resilient housing; digitalization of transport; and how green digital technology can be incorporated into strategic infrastructure policymaking and plans; as well as climate data and digital infrastructure  for enhanced forecasting and early warning systems.

This inspiring event positions training and skills development at the centre of the shift towards the low carbon economy and the achievement of the SDGs.  As highlighted by Mr. Angus Mackay, Director for Planet Division,  in his opening remarks.

“It very often comes down to a very simple equation: How many people does a country need to train, and where should those trained individuals need to be located, in order to ensure that a new policy direction actually takes root and makes a lasting difference? And this is precisely the intent behind this environmental leadership programme… to build up a cadre of national experts in resilient infrastructure development, involving all branches of government and beyond.  Too often we’ve seen well-meaning policies not achieving much impact because they are the brain child of the few rather than the many.” – Angus Mackay – Director, UNITAR

Overall, the feedback from participants was very positive, with over 90% of them reporting that the training workshop was very useful for their jobs. Additionally, many would be interested in further trainings on sustainable infrastructure. Future plans in this recurring capacity development programme include training of trainers and other specialized trainings tailored to the region’s priorities and practical needs in the field.

 

These 6 Apps Will Change the Way You Buy Food

26 October 2020

Stories

Food waste is a problem that can no longer be ignored because every bit of food that ends up in the garbage also means a waste of resources such as water, farmland, and energy needed to produce food. Some developers have taken it upon themselves to find ways to connect people to food that would go to waste, and so helping to reduce the amount of food thrown out every day. Here are six apps that will change the way you buy food.

In a world where one in nine people on earth (about 795 million people) don’t have food to eat, we continuously waste 1.3 billion tons of edible food each year, according to the Food and Agriculture Organization. This means that one-third of all the food produced for human consumption is lost.

Selecting flawless vegetables and fruits has become a habit for many consumers. Bright yellow bananas without any brown spots, perfectly shaped orange bell peppers, and apples that have an impeccable red glow sans bruises. In reality, this “harmless” habit contributes to perfectly edible food getting thrown out because of how it looks. Ultimately, food waste is responsible for over seven percent of the world’s greenhouse gas emissions (GHGs), making it a key challenge in tackling climate change.

Did you know that in the United Kingdom, 1.4 million bananas are thrown away every day?

Food waste is a problem that can no longer be ignored because every bit of food that ends up in the garbage also means a waste of resources such as water, farmland, and energy needed to produce food in the first place. Some developers have taken it upon themselves to find ways to connect people to food that would otherwise go to waste, and so helping to reduce the amount of food thrown out every day.

YourLocal: To fight food waste in Denmark, two friends came up with the idea to link consumers to local shops that have leftover food. Given its success, in 2015 YourLocal became the first app to help small businesses and supermarkets sell surplus food that would otherwise go to waste.
The app is available for iPhone and Android.

Too Good To Go: The concept is simple: through a free smartphone app, Too Good To Go helps food stores sell their surplus food instead of throwing it away. The best part? People get to enjoy good food at a fraction of the price. This free smartphone app is available in Belgium, Denmark, France, Germany, the Netherlands, Norway, Switzerland and the UK, with plans to expand to other countries. If you live in one of these countries, start saving on food today.
The app is available for iPhone and Android.

In 2017, Too Good To Go users saved over 2 million meals that would probably have ended in the garbage.

Olio: Next time you are going on a long weekend getaway, think about sharing your vegetables and fruits with your neighbor. This app allows users to connect with neighbors or local shops that have surplus food. You can also browse for food that’s available nearby (all products are free or for donation to charity) and arrange for a pick-up.
The app is available for iPhone and Android.

No Food Wasted: This app allows people in the Netherlands to know when products that are close to their “best-before” date go on sale at their local supermarket. This means you can quickly change your shopping list, buy products that are marked down, and save money.
The app is available for iPhone and Android.

In developing countries, 40 percent of losses occur during the harvest and processing level. In industrialized countries, 40 percent of losses happen at the retail or consumer level. Source: FAO.

We Save Eat: To tackle food waste in Barcelona, stores post their surplus food on We Save Eat and users are able to purchase products at a reduced price. If you own a food shop in Barcelona, you can sign up to be part of the We Save Eat community.
The app is available for iPhone and Android.

Flashfood: Available in the United States and Canada, Flashfood allows people to immediately browse food deals near them. This not only saves money for shoppers, but it increases revenues for vendors while contributing to diminishing environmental impacts.
The app is available for download here.

Become conscious about your food consumption is the first step toward a sustainable lifestyle. However, you can take a further step and learn in-depth on how your diet impacts the environment and our planet by taking our e-course on Sustainable Diet, currently available in English and Portuguese.

Welcome

World trade patterns show that while many developing countries are now playing an increasing role in trade, many other—and particularly least developed countries who account for less than 1% of all global trade—remain stranded on the margins. Still heavily reliant on natural resource-based products and raw materials for their exports, these countries are highly vulnerable to economic and environmental shocks.

The transition to an inclusive green economy represents many significant opportunities. By harnessing the increasing global demand for environmental goods and services, as well as consumer demand for more sustainable products, countries can diversify their economies, reduce their commodity dependence and boost their competitiveness. Thus, societies promote long-term, sustainable development while also strengthening their capacity to tackle the manifold environmental challenges lying ahead.

Trade can also power a green economic recovery from COVID-19. Global demand for environmental goods and services is expected to rise as countries roll out economic stimuli with larger earmarks for climate-friendly solutions. While this course was developed prior to the outbreak of COVID-19, its contents therefore remain relevant to current policy discussions.

One practical challenge lies in ensuring that countries are both aware of these opportunities and that they possess the knowledge and skills to take advantage of them. To address this challenge, the course sets out to provide interested participants from government, business, and civil society with an introduction to the various approaches that may be taken to harness green trade opportunities.

If you encounter any difficulty or if you have any questions, please consult our help page.

What will you learn?

Participants completing the course will be able to:

  • Outline the evolution of legal and governance frameworks underpinning the trade and green economy interface
  • Identify perceived challenges and potential opportunities related to trade in the transition to a green economy
  • Describe enabling policy conditions to foster green trade practices
  • Highlight sectoral case studies of green trade in action

Course structure at a glance

The course aims to provide participants with a solid understanding of the policy instruments and enabling conditions needed for countries to advance the green economy transition via green trade, and vice-versa. It contains four lessons, each taking approximately 20 minutes to complete:

  1. The trade and environment interface
  2. Perceived tensions and synergies between trade liberalization and the green economy
  3. Enabling conditions and policy design for green trade
  4. Seizing sectoral opportunities

Welcome

The COVID-19 pandemic exposed many fragilities of our economies and deepened existing inequalities and imbalances. However, long before the pandemic hit nations across the world, many economies were marked by harmful and inefficient use of public and private resources, reinforcing environmental degradation, biodiversity loss, global warming and vulnerabilities linked to health and social exclusion. In the wake of the health and economic crisis, citizens are increasingly demanding a departure from business-as-usual approaches in favour of truly innovative and green policies. Similarly, many governments recognize that the transformative potential of this circumstance must not be wasted.

Greening recovery efforts can help nations build forward better after the pandemic to increase the well-being of people and resilience of countries to future crises. Green fiscal policies in particular can play a key role in countries’ recovery efforts by removing inefficiencies in public expenditures and raising additional fiscal revenues which can be directed towards immediate COVID-19 relief measures while supporting longer-term investments.  While this course was developed prior to the outbreak of COVID-19, its contents therefore remain relevant to current policy discussions.

One practical challenge lies in ensuring that countries are both aware of these opportunities and that they possess the knowledge and skills to take advantage of them.

Learning About Climate Change in Argentina

25 August 2020

Stories

Young activists and researchers from Argentina participated in a tailored workshop on climate change mitigation. They discussed ways on how to prepare cities for the context of climate change and how a local cooperative can play a key role in raising awareness at the community level.

The countries of the Southern Cone are no exception to the greater frequency and intensity of extreme events due to climate change. According to the National Meteorological Service, 2017 was the warmest recorded year in the history of Argentina, both in the summer and winter, with an average annual temperature of 16.66°C. In addition to the progressive rise in temperature, variations in precipitation have resulted in more intense rains and longer periods of drought throughout the country.

Poster of the workshop, disseminated through the channels of CEVA, FECOOTRA, CECOOP, the Secretary of Extension of the Faculty of Natural Sciences and the Museum of the UNLP.

For the first time, the Center for Education and Cooperative Training (CECOOP) of the Federation of Cooperatives of Labor of the Argentine Republic (FECOOTRA), together with the José María Arizmendiarrieta Study Center, held a workshop focused on climate change. Following UN CC:Learn’s premise of “leaving no one behind” in its goal of disseminating knowledge on climate change, CECOOP organized the workshop so that any interested person could attend, without any registration costs for participants.

According to Guillermo Villate, the workshop was carried out within the framework of the principles of commitment to the community and to the environment, from which the CECOOP proposes to raise awareness at the community level, with regard to taking care of the environment.

CECOOP based the training on the material of the UN CC:Learn Introductory e-Course on Climate Change, which provides the foundations of climate change, covering topics from climate science to governance. Over the past three years, thousands of people around the world have learned about climate change and its threats through this online course. In terms of education on climate change, this is the United Nations initiative with greatest reach, since it is a free course and is currently available in five languages.

The workshop motivated the exchange of ideas and experiences, generating debates and making the learning experience more enriching on what to do to face climate change and the activities that produce CO2. In addition to the content of the UN CC:Learn course, complementary activities were carried out with access to other documentary materials, videos and a closing Interdisciplinary Lecture on Climate Change with researchers from the Faculty of Natural Sciences and the National University of La Plata Museum.

The delivery of the workshop was approached from the perspective of the city of La Plata, where the case of mitigation to climate change was exposed particularly in Argentina, through the experiences of the cooperative “Creando Conciencia”. The mission of this Cooperative is to take care of the environment through the differentiated collection of waste with final disposal of each of them according to their characteristics. It also classifies, conditions and reinserts recyclable waste.

Among the participants of the workshop was a victim of the floods that occurred in 2013. Since then, Francisca Pinto has set out to register indicators, which she seeks to transfer to a digital format in the future, so that these serve as a source of information to benefit society in the legislative, administrative and training fields.

I could understand an issue that is not how it should be discussed within society and at the political level. I thought it was an interesting initiative that would be good to replicate in other places to continue to reach more people to generate collective awareness and allows to put on the world’s agenda the solution to the challenge of climate change.“ – Manuel María De Arrieta, participant of the workshop on climate change.

Upon the positive experience and good reception of the workshop, CECOOP intends to continue replicating the course in different regions of the country and include other fields of study among them, for example, how to prepare cities for the context of climate change through infrastructure. They also intend to continue raising awareness among communities about climate change and generate a collective interest in this important issue that threatens the entire world.

Not everyone in his network has knowledge of how cities cause or contribute to climate change. For Nura, taking the course on cities “improved his career goal as a climate change solution enthusiast.”

Hungry to learn more, Nura decided to enroll in other courses offered by UN CC:e-Learn. He took the Children and Climate Change course and the REDD+ Academy e-course. He completed and received certificates for these courses too.

The three courses really enhanced my career goals and aspirations as a UN Designated Contact Point on climate change in Nigeria. It also rekindled a ray of hope in me because I never thought that I would find such important courses online and for free!” he says.

I am really happy to be obtaining formal training certificates on climate change and its impact on our societies through UN CC:e-Learn,” he adds.

Nura encourages others to visit the UN CC:e-Learn platform and register for any of the courses available.

Any of these courses will change one’s point of view on how climate change is affecting our cosmopolitan planet. I encourage all to do it, because climate change is everybody’s business.”

New e-course: Integrating Climate Risk Information into NAPs

29 November 2019

News

UN CC:Learn and WMO launch a joint new e-course to enhance climate information for climate actions. Registration open!

While to date, 197 UNFCCC members have signed the Paris Agreement and 187 ratified it, thus pledging to keep the increase in global average temperature well below 2°C above pre-industrial levels, it remains a challenging endeavor.

Member states need to make choices between a range of possible actions requiring information on past, present and potential future climate conditions. Adapting to climate change requires the development of the best available scientific information about climate change trends and their societal impacts. The generation and use of climate information for planning and decision-making should be strengthened, drawing on the best available climate observations, data and science.

To ensure the best societal outcomes from climate action, information on past, present and potential future climate conditions should be systematically integrated into national adaptation policies and project planning. The relevance and adequacy of climate information for decision-making can be identified through multi-stakeholder and country-level processes, drawing on the resources of the global hydro-meteorological community and information flowing across global to local scales. Synergies must be enabled among communities that produce climate information and those who use it for climate action. While producers gather, analyze and compile climate information, users need to know what kind of information is available out there that can support adaptation planning.

The course Integrating Climate Risk Information into NAPs, developed by the World Meteorological Organization (WMO), the Global Framework for Climate Services (GFCS), and the United Nations Institute for Training and Research (UNITAR) comes to support communities showing how to strengthen National Adaptation Plans (NAPs) through appropriate climate information and coordinated policy action, enabling various institutions and actors to work together in a collaborative framework.

The course answers several questions:

  • Why is climate information important in adaptation planning and decision making?
  • What are the technical resources for assessing climate risks?
  • What is the role of National Hydro-meteorological Services in the NAP process?
  • How can priority climate actions be enhanced by climate scientific information?
  • What climate products and services that support NAPs are out there?

The course is designed to respond the learning needs of climate services providers (National Hydro-meteorological Services, research/academic and international organizations), and users (e.g. decision-makers, private investors, non-governmental organizations, etc.), as well as of those working at the science-policy interface for outreach or communication purposes.

The course may eventually catalyze innovation in climate services, enabling climate information users and producers to co-produce climate knowledge, sharing feedback, engaging and connecting with different actors along the climate services value chain for the development of tailored information and products for better adaptation decision making.

This course is free of charge and you can register here.
