Human Activity Pushing More Than 1 in 5 Migratory Species Toward Extinction: UN
"The global community has an opportunity to translate this latest science of the pressures facing migratory species into concrete conservation action," said one U.N. official.
Feb 12, 2024
As world governments gathered in Uzbekistan Monday for the United Nations conference on migratory species, they centered the theme "Nature Knows No Borders"—an idea that a new landmark report said must take hold across the globe to push policymakers in all countries and regions to protect the billions of animals that travel each year to reproduce and find food.
The Convention on the Conservation of Migratory Species of Wild Animals (CMS) marked the opening of the 14th Conference of the Parties (CMS COP14) to the United Nations biodiversity treaty by releasing the first-ever State of the World's Migratory Species report, showing that nearly half of migrating species are declining in population.
The crisis is especially dire for more than 1 in 5 species that are threatened with extinction, and 70 species listed under the CMS which have become more endangered, including the steppe eagle, the Egyptian vulture, and the wild camel.
The populations of nearly all species of fish listed in the U.N. treaty, including sharks and rays, have declined by 90% since the 1970s.
The two biggest drivers of endangerment and threatened extinction are overexploitation—including incidental and intentional capture—and habitat loss, and both are directly caused by human activity.
Seven in 10 CMS-listed species are threatened by overexploitation, while 3 in 4 of the species are at greater risk of dying out due to habitat loss, as humans expand energy, transportation, and agricultural infrastructure across the globe.
The climate crisis and planetary heating, pollution, and the spread of invasive species—thousands of which are introduced by humans—are also major threats to migratory species, the report says.
"Unsustainable human activities are jeopardizing the future of migratory species—creatures who not only act as indicators of environmental change but play an integral role in maintaining the function and resilience of our planet's complex ecosystems," said Inger Andersen, undersecretary-general of the U.N. and executive director of the U.N. Environment Program (UNEP). "The global community has an opportunity to translate this latest science of the pressures facing migratory species into concrete conservation action. Given the precarious situation of many of these animals, we cannot afford to delay."
Migratory species "reinforce" the fact that nature does not observe borders put in place by humans, Andersen added in a video posted on social media, and humans must work across borders to ensure these species are protected.
According to the report, nearly 10,000 of the world's key biodiversity areas are crucial for the survival of migratory species, but more than half are not designated as areas that must be conserved—and 58% are under threat due to human activities.
Mapping and taking adequate steps to protect "the vital locations that serve as breeding, feeding, and stopover sites for migratory species" is a key priority, said the CMS in a statement.
"Migratory species rely on a variety of specific habitats at different times in their lifecycles," said Amy Fraenkel, CMS executive secretary. "When species cross national borders, their survival depends on the efforts of all countries in which they are found. This landmark report will help underpin much-needed policy actions to ensure that migratory species continue to thrive around the world.”
In addition to increasing understanding of migration paths and minimizing human infrastructure in the pathways, the report recommended that policymakers "strengthen and expand efforts to tackle illegal and unsustainable taking of migratory species"; scale up efforts to tackle climate change and light, noise, chemical, and plastic pollution; and consider expanding CMS listings to include more at-risk migratory species in need of international attention.
"There are many things that are needed to be done on addressing the drivers of environmental change, such as agriculture for habitat destruction, the sprawl of cities, we have to look at rail, road, and fences," said Fraenkel. "One of the most important things for migratory species is something we call ecosystem integrity: they need particular sites to breed, feed, and travel. If those sites cannot be accessed or don’t exist any more, then it's obviously going to be detrimental."
The report focused on 1,189 migratory species identified by the U.N. as needing protection, but found that another 399 migratory species are either threatened or near threatened with extinction.
"People might not realize that whales, lions, gorillas, giraffes, and many birds are migratory species," Fraenkel said.
At the opening ceremony of CMS COP14, Andersen called on policymakers to live up to the conference's theme "by ensuring free passage of migratory species and by ensuring that, through multilateralism, we reach a hand across every border to ensure long-term sustainability, for people and for planet."
Reversing population decline is possible, the report emphasized, pointing to coordinated local action in Cyprus that reduced illegal bird netting by 91% and "hugely successful" conservation and restoration work in Kazakhstan, "which has brought the saiga antelope back from the brink of extinction."
"I ask parties to consider how to work in harmony with other processes for mutually assured success," said Andersen, "all in the interests of sustainable economies and societies."

'Emissions Canyon': World on Track for 2.9°C of Warming
Keeping the 1.5°C temperature goal alive "requires tearing out the poisoned root of the climate crisis: fossil fuels," U.N. Secretary-General António Guterres said.
Nov 20, 2023
Nations' current unconditional climate action plans under the Paris agreement would put the world on track for 2.9°C of warming by 2100, the United Nations Environment Program warned Monday.
The UNEP's 2023 Emissions Gap Report, released ahead of next week's U.N. Climate Change Conference (COP28) in the United Arab Emirates, finds that policymakers must slash greenhouse gas emissions by 28% by 2030 to limit warming to 2°C above preindustrial levels and 42% to halt warming at 1.5°C.
"The report shows that the emissions gap is more like an emissions canyon," U.N. Secretary-General António Guterres said in a statement. "A canyon littered with broken promises, broken lives, and broken records. All of this is a failure of leadership, a betrayal of the vulnerable, and a massive missed opportunity."
The annual Emissions Gap Report calculates the difference between climate-warming emissions under current policies and what needs to be achieved to limit global heating to "well below" 2°C and ideally 1.5°C. This year's report highlighted 2023's string of broken temperature records and extreme weather events: Scientists predict it's on track to be the hottest year in 125,000 years.
At the same time, global greenhouse gas emissions rose by 1.2% between 2021 and 2022, hitting a record 57.4 gigatonnes of carbon dioxide equivalent (GtCO2e) last year.
"Humanity is breaking all the wrong records when it comes to climate change," UNEP Executive Director Inger Andersen said in the report foreword.
"The 2023 edition of the Emissions Gap Report tells us that the world must change track, or we will be saying the same thing next year—and the year after, and the year after, like a broken record," Andersen added.
Even the report's full title expressed a sense of exasperation: Emissions Gap Report 2023: Broken Record—Temperatures hit new highs, yet world fails to cut emissions (again).
The report looked at both existing and promised policies, including countries' Paris action pledges, known as nationally determined contributions (NDCs). It did find that national actions since the Paris agreement was negotiated in 2015 have made a difference. At the time, greenhouse gas emissions were projected to rise by 16% by 2030 and now they are on track to rise by 3% by the end of the decade.
But that progress is not nearly enough to avoid ever more extreme climate impacts. Currently implemented policies put the world on track for 3°C of warming by 2100, unconditional NDCs for 2.9°C, conditional NDCs for 2.5°C, and conditional NDCs combined with net-zero pledges give temperatures a 66% chance of topping out at 2°C. Under the last, most optimistic scenario, the world is left with a 14% chance of limiting warming to 1.5°C. However, net-zero pledges are not currently seen as reliable, since no Group of 20 country is on pace to reduce its emissions in line with this goal.
The report found that nations must cut their emissions by 14 GtCO2e by 2030 to reach 2°C and 22 GtCO2e to reach 1.5°C. The way this can be done is by phasing out fossil fuels as soon as possible.
"The only way to curtail this spiraling crisis is through wholesale changes to the global energy system that will sharply drive down all heat-trapping emissions."
"We know it is still possible to make the 1.5°C limit a reality. And we know how to get there—we have roadmaps from the International Energy Agency and the IPCC [Intergovernmental Panel on Climate Change]," Guterres said. "It requires tearing out the poisoned root of the climate crisis: fossil fuels. And it demands a just, equitable renewables transition."
The report comes as nations prepare to gather on November 30 for COP28, which will include the first global stocktake of their progress toward meeting the goals of the Paris agreement. This will lead to a new round of NDCs through 2035.
"Ambition in these NDCs must bring greenhouse gas emissions in 2035 to levels consistent with the 2°C and 1.5°C pathways. Stronger implementation in this decade will help to make this possible," Andersen said in the foreword.
"The world needs to lift the needle out of the groove of insufficient ambition and action, and start setting new records on cutting emissions, green and just transitions, and climate finance—starting now," Andersen added.
In response to the report, Rachel Cleetus, the policy director and a lead economist in the Climate and Energy Program at the Union of Concerned Scientists, also called for ambition at the upcoming climate talks.
"The only way to curtail this spiraling crisis is through wholesale changes to the global energy system that will sharply drive down all heat-trapping emissions," Cleetus said. "At COP28, nations must heed these scientific truths by agreeing to a fast and fair phaseout of fossil fuels, ramping up renewable energy and energy efficiency, and significantly expanding climate finance commitments from wealthier countries for an equitable clean energy transition."

UN Provides Blueprint for 80% Cut to Global Plastic Pollution by 2040
"If we follow this roadmap, including in negotiations on the plastic pollution deal, we can deliver major economic, social, and environmental wins," said the director of the U.N. Environment Program.
May 16, 2023
Global plastic pollution can be reduced by 80% by 2040 if countries and companies make far-reaching changes using existing technologies, according to a report published Tuesday by the United Nations Environment Program.
Turning Off the Tap: How the World Can End Plastic Pollution and Create a Circular Economy comes less than two weeks before the start of a second round of negotiations in Paris on a legally binding global plastics treaty. While the required shifts outlined in the report are significant, UNEP stresses that they are practical, relatively inexpensive, and would yield benefits valued at more than $4.5 trillion.
Research has shown that plastic pollution is a life-threatening crisis poised to grow worse unless governments intervene to prevent fossil fuel and petrochemical corporations from expanding the production of single-use items.
"The way we produce, use, and dispose of plastics is polluting ecosystems, creating risks for human health, and destabilizing the climate," UNEP executive director Inger Andersen said in a statement. "This UNEP report lays out a roadmap to dramatically reduce these risks through adopting a circular approach that keeps plastics out of ecosystems, out of our bodies, and in the economy."
"If we follow this roadmap, including in negotiations on the plastic pollution deal," said Andersen, "we can deliver major economic, social, and environmental wins."
The report proposes a four-fold "systems change" to address "the causes of plastic pollution, rather than just the symptoms." As UNEP summarizes, it consists of the following:
- Reduce: By first eliminating problematic and unnecessary plastics, policymakers can reduce the size of the problem.
- Reuse: Promoting reuse options—including refillable bottles, bulk dispensers, deposit-return schemes, packaging take-back schemes, etc.—can reduce 30% of plastic pollution by 2040. To realize its potential, governments must help build a stronger business case for reusable items.
- Recycle: Reducing plastic pollution by an additional 20% by 2040 can be achieved if recycling becomes a more stable and profitable venture. Removing fossil fuels subsidies, enforcing design guidelines to enhance recyclability, and other measures would increase the share of economically recyclable plastics from 21 to 50%.
- Reorient and Diversify: Careful replacement of products such as plastic wrappers, sachets, and takeaway items with products made from alternative materials (such as paper or compostable materials) can deliver an additional 17% decrease in plastic pollution.
"Even with the measures above, 100 million metric tons of plastics from single-use and short-lived products will still need to be safely dealt with annually by 2040—together with a significant legacy of existing plastic pollution," UNEP explains. "This can be addressed by setting and implementing design and safety standards for disposing of non-recyclable plastic waste, and by making manufacturers responsible for products shedding microplastics, among others."
According to the agency: "Theshift to a circular economy would result in $1.27 trillion in savings, considering costs and recycling revenues. A further $3.25 trillion would be saved from avoided externalities such as health, climate, air pollution, marine ecosystem degradation, and litigation-related costs. This shift could also result in a net increase of 700,000 jobs by 2040, mostly in low-income countries, significantly improving the livelihoods of millions of workers in informal settings."
Although UNEP's recommendations necessitate a substantial investment, it is "below the spending without this systemic change: $65 billion per year as opposed to $113 billion per year," the agency notes. "Much of this can be mobilized by shifting planned investments for new production facilities—no longer needed through reduction in material needs—or a levy on virgin plastic production into the necessary circular infrastructure. Yet time is of the essence: a five-year delay may lead to an increase of 80 million metric tons of plastic pollution by 2040."
While many progressive advocacy groups are likely to welcome UNEP's overall message that readily available solutions, backed by strong regulatory instruments, can help bring about a transformation from a "throwaway" society to a "reuse" society, the agency is facing criticism for its promotion of burning plastic waste in cement kilns.
"Burning plastic waste in cement kilns is a 'get out of jail free card' for the plastic industry to keep ramping up plastic production by claiming that the plastic problem can be simply burned away," Neil Tangri, science and policy director at the Global Alliance for Incinerator Alternatives (GAIA), said in a statement. "Not only does this pose a grave climate and public health threat, it also undermines the primary goal of the global plastic treaty—putting a cap on plastic production."
Larisa de Orbe of the Mexican environmental justice groups Red de Acción Ecológica and Colectiva Malditos Plásticos echoed Tangri's argument.
"To tackle the plastic crisis, waste should not be burned, but its production should be drastically reduced, and single-use plastics should be banned," said Orbe. "Environmental authorities in Mexico and the [U.N.] Human Rights Rapporteur on Toxic Substances have recognized that the burning of waste in cement kilns has caused environmental disaster and the violation of human rights in the territories and communities near these activities."
Imports of plastic waste into Mexico grew by 121% between 2018 and 2021. As GAIA noted, a large portion of that "is suspected to be burned in cement kilns, which operate with few controls or emissions monitoring systems."
Linda Birnbaum, former director of the National Institute of Environmental Health Sciences and National Toxicology Program, called the U.N.'s promotion of burning of plastic waste in cement kilns "an irresponsible choice that has significant health implications for the communities living nearby."
"Burning plastic waste releases dioxins that stay in the environment forever, and are linked to cancers, reproductive, and developmental impairments," said Birnbaum. "These are the very same chemicals that are threatening the residents of East Palestine, Ohio."
Ahead of the first round of global plastic treaty negotiations in December, civil society organizations, scientists, and other advocates demanded robust rules to confront the full lifecycle impacts of the plastic pollution crisis.
After talks opened, the Break Free From Plastic (BFFP) alliance, comprised of more than 100 groups, emphasized the need to limit the ever-growing production and consumption of plastic and hold corporations accountable for the ecological and public health harms caused by manufacturing an endless stream of toxic single-use items.
The coalition launched a petition outlining what it described as the "essential elements" of a multilateral environmental agreement capable of "reversing the tide of plastic pollution and contributing to the end of the triple planetary crises of climate change, biodiversity loss, and pollution." According to experts associated with BFFP, an effective pact must include:
- Significant, progressive, and mandatory targets to cap and dramatically reduce virgin plastic production;
- Legally binding, time-bound, and ambitious targets to implement and scale up reuse, refill, and alternative product delivery systems;
- A just transition to safer and more sustainable livelihoods for workers and communities across the plastics supply chain; and
- Provisions that hold polluting corporations and plastic-producing countries accountable.
While the U.N.'s Intergovernmental Negotiating Committee meetings in December (INC-1) and those scheduled to begin later this month (INC-2) mark the first time that governments have met to develop global regulations to restrict plastic production, the United States and the United Kingdom—the world's biggest per-capita plastic polluters—have so far refused to join a worldwide treaty aimed at curbing the amount of plastic waste destined for landfills and habitats, though both countries are reportedly now open to the idea.
