How UNEP is helping education systems go green
The world is facing a three-pronged environmental crisis of climate change, nature and biodiversity loss, and pollution and waste. To turn around the planet’s fortunes, the participation of young people will be key, says Sam Barratt, Head of the United Nations Environment Programme (UNEP) Youth, Education and Advocacy Unit.
Ahead of the International Day of Education on 24 January, we spoke to Barratt about the role of young people in reviving the natural world and what UNEP is doing to enlist their support.
Lots of different players are involved in youth education. What is UNEP’s mandate?
Sam Barratt (SB): The UN Educational, Scientific and Cultural Organization (UNESCO) is the lead on education in the UN system. But here at UNEP, we work closely with them, focusing on non-formal education and higher education. This mandate allows us to work with major global partners and networks that can reach millions to bring environmental issues into the curriculum of schools, on to university campuses, into massive games, such as Subway Surfers, or even into Scout and Girl Guide badge curricula. It’s a huge opportunity to shift norms and reach billions of youth, both inside and outside the classroom.
Collaborating with universities to promote sustainable development seems to be a key aspect of UNEP’s education work. Is that right?
SB: Yes, it’s huge as universities produce the leaders of tomorrow. Our approach is to see how universities can be Petri dishes to shift the habits of students. In September 2020, UNEP launched The Little Book of Green Nudges in 136 campuses around the world. It’s a quick guide composed of 40 nudges to spark sustainable behaviour among students and staff.
In 2021 we launched UNEP’s Sustainable University Framework, which seeks to define what it means to be a sustainable university and lays out a pathway to becoming one, and the Global Guidance for Education on Green Jobs. These initiatives are designed to give the higher education community, employers and youth organizations the tools to prepare students to participate in a green transition.
And in October 2021, UNEP worked with Times Higher Education to organize the inaugural Climate Impact Forum at which Times Higher Education launched its new data-led report, The Race to Net Zero. It presented how well higher education institutions across the globe are performing when it comes to reducing their own greenhouse gas emissions and transitioning to net zero. So far 1,086 universities from 68 countries, representing over 10 million students, made commitments to reach net-zero emissions by 2050.
What are you doing to support developing countries?
SB: There are already lots of networks in Europe and North America, but we want to focus on emerging economies. Given this, we’ve launched the Africa Green University and Youth Education Network hosted by the Hassan II International Centre for Environmental Training in Morocco. The network is growing and now includes 22 universities from eight African countries. With the support of the TERI School of Advanced Studies, we talked to stakeholders who agreed that there is a need to establish an India Green University Network. The plan is for this network to be built up and officially launched in 2022.
Any initiatives specifically on the climate front?
SB: Yes. We’ve provided early support for initiatives such as Count Us In, a campaign that aims to inspire 1 billion people to take simple, impactful actions which will directly reduce carbon dioxideemissions, accelerate the uptake of climate solutions and challenge leaders to act boldly to deliver global systems change.
Hundreds of millions of young people play video games. How is UNEP working with the video gaming industry to promote environmental awareness?
SB: UNEP facilitates the Playing for the Planet Alliance, which is an initiative in support of the video gaming industry to use their influence, reach, and creativity to address some of the world’s biggest environmental challenges. Gaming companies in the alliance have made commitments ranging from integrating green activations in games to reducing their emissions. Since the Playing for the Planet Alliance was launched in 2019, 60 per cent of its members have made a commitment to become net zero or carbon negative by 2030. On top of that, the second annual Green Game Jam welcomed 30 (game) studios with a combined reach of 1 billion players.
UNEP’s GEO-6 for Youth report shows how youth have the power to bring about transformative change for the environment. How is UNEP getting youth to help tackle the scourge of single-use plastics?
SB: The Tide Turners Plastic Challenge Badge seeks to support the World Organization of the Scout Movement, the World Associations of Girl Guides and Scouts, Junior Achievement and university students to take action to reduce single-use plastic in their lives. Since February 2019, more than 470,000 young people have started the badge in over 32 countries in Africa, Asia and the Caribbean. Thanks to financial support from the United Kingdom government this work will continue in 2022.
UNEP and partners launched “Earth School” in April 2020 in response to school closures in the wake of the pandemic. In just three weeks, it reached nearly 1 million students. How did you come up with such an idea?
SB: We saw that many pupils, parents and teachers were struggling with COVID-19 so we wanted to try and do something different. Earth School was built with educators and over 40 partners and shows what can happen when a big idea is run by many. It’s the biggest online learning initiative in UNEP’s history and is available for free on TED-Ed’s website.
Largest river and wetland restoration initiative in history launched at UN Water Conference
A coalition of governments today launched the Freshwater Challenge – the largest ever initiative to restore degraded rivers, lakes and wetlands, which are central to tackling the world’s worsening water, climate and nature crises.
Announced at the UN Water Conference in New York, the Freshwater Challenge aims to restore 300,000km of rivers – equivalent to more than 7 times around the Earth – and 350 million hectares of wetlands – an area larger than India – by 2030.
Along with water supplies, healthy freshwater ecosystems provide a wealth of benefits to people and nature, and are critical to mitigating and adapting to climate change, and achieving the Sustainable Development Goals (SDGs). Yet one-third of the world’s wetlands have been lost over the past 50 years, and we are still losing them faster than forests. Rivers and lakes are the most degraded ecosystems in the world, with fish populations, many of which are vital for community food security, pushed to the brink.
Released this week, the IPCC’s sixth assessment report outlines the serious impacts of climate change on freshwater ecosystems, highlighting the need to protect and restore them to enhance adaptation and build resilient societies, economies and ecosystems.
Championed by the governments of Colombia, the Democratic Republic of Congo, Ecuador, Gabon, Mexico and Zambia, the Freshwater Challenge calls on all governments to commit to clear targets in their updated National Biodiversity Strategies and Action Plans, National Determined Contributions and National Implementation Plan for the SDGs to urgently restore healthy freshwater ecosystems.
Susana Muhamad, Minister of Environment and Sustainable Development, Colombia: said”This initiative is in line with the priorities of the National Development Plan 2022-2026, which will allow the country to strengthen Territorial Planning around Water by protecting all water systems from a perspective of water as a common resource and fundamental right. This implies the participation of communities to resolve socio-environmental conflicts, respecting cultural diversity and guaranteeing the conservation of biodiversity”.
The Freshwater Challenge is a country-driven initiative with an inclusive, collaborative approach to implementation, where governments and their partners will co-create freshwater solutions with indigenous people, local communities, and other stakeholders.
Building on the Global Biodiversity Framework agreed in Montreal in December 2022, which included the restoration of 30% of the world’s degraded ‘inland waters’, the Challenge will contribute to the UN Decade on Ecosystem Restoration. The UN Decade is a drive to revive our planet, co-led by the United Nations Environment Programme (UNEP) and the UN Food and Agriculture Organization (FAO).
Inger Andersen, UNEP Executive Director said, “Healthy rivers, lakes and wetlands underpin our societies and economies, yet they are routinely undervalued and overlooked. That is what makes the commitment by the governments of Colombia, DR Congo, Ecuador, Gabon, Mexico and Zambia so commendable. While countries have pledged to restore one billion hectares of land, the Freshwater Challenge is a critical first step in bringing a much-needed focus on freshwater ecosystems.”
Stuart Orr, Freshwater Lead at WWF International said, “The clearest sign of the damage we have done – and are still doing – to our rivers, lakes and wetlands is the staggering 83% collapse in freshwater species populations since 1970. The Freshwater Challenge puts the right goals and frameworks in place to turn this around – benefiting not only nature but also people across the world. We need governments and partners to commit to this urgently as part of the Water Action Agenda coming out of this UN conference.”
The Freshwater Challenge will focus on providing the evidence needed at country level to effectively design and implement restoration measures, identify priority areas for restoration, update relevant national strategies and plans, and mobilise resources and set up financial mechanisms to implement the targets.
Championed by the coalition of countries, the Freshwater Challenge is supported by the UN Decade on Ecosystem Restoration, the Secretariat of the Convention on Wetlands, WWF, IUCN, The Nature Conservancy, Wetlands International and ABinBev.
Clouds in the sky provide new clues to predicting climate change
While barely being given a second thought by most people, the masses of condensed water vapour floating in the atmosphere play a big role in global warming.
By MICHAEL ALLEN
Predicting how much Earth’s climate will warm is vital to helping humankind prepare for the future. That in turn requires tackling a prime source of uncertainty in forecasting global warming: clouds.
Some clouds contribute to cooling by reflecting part of the Sun’s energy back into space. Others contribute to warming by acting like a blanket and trapping some of the energy of Earth’s surface, amplifying the greenhouse effect.
‘Clouds interact very strongly with climate,’ said Dr Sandrine Bony, a climatologist and director of research at the French National Centre for Scientific Research (CNRS) in Paris.
They influence the structure of the atmosphere, impacting everything from temperature and humidity to atmospheric circulations.
And in turn the climate influences where and what types of clouds form, according to Bony, a lead author of the Nobel Peace Prize-winning assessment report in 2007 by the United Nations Intergovernmental Panel on Climate Change.
So many processes and feedback loops can affect climate change that it’s helpful to break down the issue into smaller parts.
‘Every time we manage to better understand one of the pieces, we decrease the uncertainty of the whole problem,’ said Bony, who coordinated the EU-funded EUREC4A project that ended last year.
A number of years ago, Bony and her colleagues discovered that small, fluffy clouds common in trade wind regions cause some of the largest levels of uncertainty in climate models. These clouds are known as trade cumulus.
While trade cumulus clouds are small and relatively unspectacular, they are numerous and very widely found in the tropics, according to Bony. Because there are so many of these clouds, what happens to them potentially has a huge impact on climate.
EUREC4A used drones, aircraft and satellites to observe trade cumulus clouds and their interactions with the atmosphere over the western Atlantic Ocean, near Barbados.
Many models assume that the structure and number of these clouds will change significantly as the global temperature warms, leading to possible feedback loops that amplify or dampen climate change. The models that project a strong reduction in such clouds as temperatures rise tend to predict a higher degree of global warming.
But Bony and her colleagues discovered that trade cumulus clouds change much less than expected as the atmosphere warms.
‘In a way, it is good news because a process that we thought could be responsible for a large amplification of global warming does not seem to exist,’ she said. More importantly, it means that climatologists can now use models that more accurately represent the behaviour of these clouds when predicting the effect of climate change.
Reducing this element of uncertainty in forecasts of the global extent of warming will make predictions of local impacts such as heatwaves in Europe more precise, according to Bony.
‘The increase in the frequency of heatwaves very much depends on the magnitude of global warming,’ she said. ‘And the magnitude of global warming depends very much on the response of clouds.’
Water and ice
Meanwhile, Professor Trude Storelvmo, an atmospheric scientist at the University of Oslo in Norway, has been exploring the processes inside a different type of cloud – mixed-phased clouds – to help improve climate models.
She is fascinated by how processes in clouds that occur on a tiny, micrometre scale can have such a big influence on global-scale atmospheric and climate processes.
Mixed-phase clouds contain both liquid water and ice and are responsible for the majority of rainfall across the globe. In recent years, it has become clear that they also play an important role in climate change.
Storelvmo coordinated the EU-funded MC2 project, which ran for five years until last month and unearthed new details about how mixed-phase clouds react to higher temperatures. The results highlight the urgency of transitioning to a low-carbon society.
The more liquid water that mixed-phased clouds contain, the more reflective they are. And by reflecting more radiation from the sun away from the Earth, they cool the atmosphere.
‘As the atmosphere warms, these clouds tend to shift away from ice and towards liquid,’ said Storelvmo. ‘What happens then is the clouds also become more reflective and they have a stronger cooling effect.’
But some years ago, Storelvmo and colleagues discovered that most global climate models overestimate this effect. MC2 flew balloons into mixed-phase clouds and used remote sensing data from satellites to probe their structure and composition.
The researchers discovered that current climate models tend to make the mix of water and ice in mixed-phase clouds more uniform and less complex than in real clouds, leading to overestimations of the amount of ice in the clouds.
Because these model clouds have more ice to lose, when simulations warm them the shift in reflectiveness is greater than in real clouds, according to Storelvmo. This means the models overestimate the dampening effect that mixed-phase clouds have on climate change.
When the team plugged the more realistic cloud data into climate models and subjected it to simulated warming, they made another important finding: the increase in the reflectiveness of mixed-phased clouds weakens with warming.
While with moderate warming the dampening effect on higher temperatures is quite strong, this is no longer the case as warming intensifies.
There comes a point when the ice in the cloud has all melted and the cooling effect weakens – and then completely vanishes. Exactly when this starts to happen is a question for future research.
But, according to Storelvmo, this reinforces the need for urgent reductions in greenhouse-gas emissions.
‘Our findings suggest that if we just let greenhouse-gas emissions continue, it won’t just be a linear and gradual warming – there could be a rapidly accelerating warming when you get to a certain point,’ she said. ‘We really need to avoid reaching that point at all costs.’
As new findings on clouds such as these are integrated into models, climate predictions used by policymakers will become more refined.

Kazakhstan Discusses Ways for Achieving Carbon Neutrality and Building Resilience
Today the Ministry of Ecology and Natural Resources and the Ministry of National Economy of the Republic of Kazakhstan jointly with the World Bank and Kazakhstan Association “ECOJER” launched a series of policy dialogues to support Kazakhstan in implementing its critical climate and environmental strategies, including the transition to a low-carbon economy, air quality management, and resilience to climate change. The first of the workshop series held today focused on supporting Kazakhstan’s transition to carbon neutrality by 2060.
Kazakhstan made a bold leap forward on a newly charted course for the country’s development by adopting The Strategy on Achieving Carbon Neutrality by 2060. Approved by the President of the Republic of Kazakhstan on February 2, 2023, the strategy sets ambitious net-zero carbon goals for climate action and identifies key technological transformations needed for the country’s decarbonization. To achieve these transformations, the country will require determining and implementing effective and targeted policies and programs across the whole of the country’s economy.
“Our goal is to reduce our carbon footprint and use the benefits of sustainable economic growth, improved public health and reduced climate risks. Net investment in low-carbon technologies is estimated at $610 billion. This will certainly lead to the emergence of new and expanding existing markets and niches for domestic manufacturers, and stimulate the creation of high-skilled jobs,” said Alibek Kuantyrov, Minister of National Economy of the Republic of Kazakhstan.
Participants of the first policy dialogue discussed a roadmap for the implementation of the government policies, measures, and investments in support of the approved strategy. The event also provided a forum for the experts to share best practices and experience in low-carbon policy implementation in the Czech Republic, Germany, and Poland.
“The recently adopted strategy for Kazakhstan’s transition to carbon neutrality attests to the government’s resolve to pivot towards a growth model that is driven less by fossil fuels and more by investments in climate-smart industries in water, agriculture, and rangelands management. This broad economic transformation will require an enabling environment centered on policies, investments, and ensuring a just transition for people and communities,” says Andrei Mikhnev, World Bank Country Manager for Kazakhstan.
To help Kazakhstan prioritize the most impactful actions that can reduce greenhouse gas emissions and boost climate change adaptation while delivering on broader development goals and carbon-neutral future, the World Bank recently published Kazakhstan Country Climate and Development Report. The report suggests main pathways to support Kazakhstan’s low-carbon, resilient transition.
“Reduction of greenhouse emissions is a non-alternative course for Kazakhstan and there is an obvious need for legislative instruments. Today, government agencies need to develop the implementation roadmap, and the industry needs to get clear messages – in which direction they will move in the coming decades and what kind of support from the government they can count on. Such dialogues needed to ensure a balance of interests of state bodies and institutions, to identify business opportunities, and get knowledge of the best world experience, so that we can achieve our goals and improve the environmental situation in the country,”said Lazzat Ramazanova, Chairman of the Council of the Kazakhstan Association “ECOJER”.
The policy dialogues series aims to provide a robust platform for multi-stakeholder and multi-sectoral engagement. By bringing together Kazakhstan’s government agencies, the private sector, civil society, academia, international development organizations, and the world’s leading experts, the dialogues aim to foster collaboration and action to accelerate the implementation of Kazakhstan’s carbon neutrality targets as well as low-emission development strategy, international climate action commitments, and adaptation measures. The focus of the series’ next policy dialogues scheduled in April and June 2023 will be on air pollution reduction and climate change adaptation in support of Kazakhstan’s climate and development goals.
