Beating pollution by redesign

Ellen MacArthur

Published

Over 8 million tons of plastic pollute the oceans each year. The problem is so severe that, if nothing changes, there could be more plastic than fish in the sea by 2050. We must urgently rethink how we make and use this ubiquitous material, now a staple of our modern economy. The appetite to take action is real: public and private sector financial commitments to combat ocean pollution made at the European Union’s Our Ocean conference this year, for instance, totalled 7.2 billion euros. Yet if cleaning up is a short-term necessity, only a whole system reset will provide a long-term solution to plastics pollution and the economic losses associated with it.

Pollution is just one symptom of our hugely wasteful plastics system. It is an iconic example of our linear “take-make-dispose” economy as a whole. Forty years after the launch of the first universal recycling symbol, a report by the Ellen MacArthur Foundation to the 2016 World Economic Forum revealed that only 14 per cent of plastic packaging is collected for recycling globally: this results in a loss of $80 billion to $120 billion a year to the global economy.

Packaging is not the only culprit. The International Union for the Conservation of Nature has estimated that around half a million tons of plastic micro-fibres shed from the washing of plastic-based textiles like polyester end up in the ocean every year. The challenge is to reconcile the undeniable benefits of plastics and clothing, among other everyday products, with systems that work in the long-term and avoid pollution and the loss of valuable materials.

Can such a dilemma be solved by applying the principles of a circular economy? These are to design out pollution, keep materials in use, and build natural capital within a restorative and regenerative system. The circular economy could contribute significantly to achieving the Sustainable Development Goals which, since their adoption just two years ago, seem to be generating an unprecedented level of collaboration between private and public stakeholders.

The circular economy does not just apply to global streams of materials like plastics and textiles. Sustainable production and consumption may, at first glance, be the prime target of this system shift, but its reach is wider. Analysis from New Climate Economy, for instance, has shown that China’s air quality targets can only be achieved by combining accelerated economic restructuring, energy conservation, fuel switching and environmental policy: even the strictest end-of-pipe treatment measures could only do half the job.

Similarly, the Ellen MacArthur Foundation has found that circular economy opportunities in India’s food system could, by 2030, yield a 15 per cent reduction in spending on food, while reducing carbon dioxide emissions and the use of synthetic fertilizers and pesticides (and their associated pollution) by 21 per cent and 45 per cent respectively. The circular economy provides a positive way forward on a wide range of issues, from helping urbanization take place in a way that benefits its citizens to preserving life below water.

Realising such benefits requires a concerted effort. Revolutions do not happen by decree, so public-private dialogue around policy design must be at the heart of any serious system shift. Policymakers have an important catalysing role in both setting a direction for industries, and in putting in place mechanisms to help them move faster. The Ellen MacArthur Foundation’s Toolkit for Policymakers report provides a methodology to help structure such a transition.

Policy can be about setting the rules of the game. For plastics, for example, this could include being selective about the use of certain polymers, other chemicals or applications. Such action can be effective, cost little and garner public support. Rapid reductions in single use shopping bags – through bans or charges – have been achieved with little disruption in France, Rwanda, and the United Kingdom.

Restriction, however, is only part of the story. It must be complemented by mechanisms that foster innovation. Policymakers are well-positioned, as they can connect the design of plastic packaging with collecting, sorting and subsequently reusing or recycling it. The New Plastics Economy initiative, led by the Ellen MacArthur Foundation, aims to establish initial elements of a “Global Plastics Protocol” to address the industry’s need for common guidelines and standards in plastics design, use and reuse.

This would be a crucial step in getting all the industry actors involved in producing and using plastics packaging that can be either reused, recycled or composted – thus staying out of the environment. Policymakers’ most potent tool, however, is the ability to set high-level ambition, providing both a vision for a better system and visibility for industry. Clear signals indicating that the future will be materially different from the past must be sent to the market to help investment decisions.

The Sustainable Development Goals aim at a materially better future. We must think hard about what model of economic growth we want, since it will form the bedrock of that future. It must be fit for its purpose – promoting sustained, inclusive and sustainable economic growth, full and productive employment and decent work for all. There are several ways of looking at such a model but, whatever its complexion, it must build economic, societal, and natural capital rather than deplete it.

As voices for the planet grow louder, we must get the job done

Published

on

There is something in the air. I am not talking about pollution or greenhouse gas emissions. I am talking about the change humanity needs to address these and other environmental challenges, which have placed our planet and societies in imminent peril.

We can all sense this change: in our workplaces and schools, in our cities and communities, in the boardroom and in the media, in parliaments and city councils, in laboratories and business incubators.

People from all corners of the world are demanding a fundamental redesign of how we – as individuals and as a society – interact with the planet. There is a clear understanding that we must live within the limits of our natural world. In response, we are seeing humanity’s astonishing capacity for innovation and imagination turn towards finding solutions.

Never before has the environmental mandate been more visible, recognized and acted upon. But then again, never before have the stakes been higher.

Pollution of air, land and water is poisoning the planet, from the deepest ocean trench to the highest mountain peak. The latest climate alarm, from the Intergovernmental Panel on Climate Change, told us how little time we have to ward off the worst impacts of climate change. Scientists from many different bodies are warning that human activity is devastating biodiversity – threatening livelihoods, food security and society as we know it.

We have serious work to do. We need to ensure a healthy environment for all, which is essential to development, peace, stability and the eradication of poverty. We need to change our environmental footprint: how we use and discard, how we plan and build, how we power our societies, how we measure growth, and how we share the planet with other species.

Today, as I take up the leadership of the United Nations Environment Programme, I am convinced that we can get this job done, together. Environmental management and sustainability have been at the core of my personal journey since my first job in the 1980s in Sudan, where I worked on drought and desertification issues. I have seen what people can achieve when they work with each other towards an important goal.

In these days of change, the organization I am leading is critical. The United Nations Environment Programme is the link between science and policy action by governments – which is a key driving force for change. The organization’s Medium-Term Strategy (2018-2021) and accompanying Programme of Work informs, supports and assists nations as they work towards a sustainable future. This Programme of Work – which guides every action the organization takes – is fully aligned with the Sustainable Development Goals, the Paris Agreement and many other international processes. We collaborate just as closely with civil society and the private sector, without whom change at the speed and scale we need simply will not be possible.

We also have a long history of horizon watching, of identifying waves that are coming to our shores, and supporting nations as they come to agreements around issues that require coordinated global action. The United Nations Environment Programme hosts the secretariats of many multilateral agreements on environmental themes: from biodiversity and ecosystems to regional seas, from chemical waste management to protecting the ozone layer. I look forward to supporting these agreements so that their ambitious goals can be achieved.

The UN Environment Programme is here to support the wider UN system and every process linked to environmental action. In September this year, at the UN Secretary-General’s Climate Action Summit, countries will showcase a leap in collective ambition. In 2020, at the next meeting of the UN Convention on Biological Diversity, the world will agree on new and – I hope – ambitious targets to arrest biodiversity loss. Whatever my organization can do to support these encouraging moves, we will do.

Like any organization, though, we must evolve and improve. I have taken to heart the changes demanded of this organization. I will work closely with my dedicated staff, management and Member States to make sure we drive forward, while learning from the past. We will adhere to the high standards expected of an institution with such a powerful global mandate: safeguarding life on earth.

As we work ever harder and better, our success will not be defined by a report or a conference, but by how we support Member States and their people to shift the needle.

Success for us means halting the rapid loss of species. It means preventing seven million people from dying of air pollution each year. It means countries taking action towards sustainable consumption and production. It means a planet powered by clean energy. It means all of humanity reaping the benefits of a healthy and thriving environment for centuries to come.

Today, as I arrive in beautiful Kenya, I will do everything I can to work with staff, Member States and partners to make this happen.

Restoring the Caribbean to the paradise it used to be

MD Staff

Published

on

When people think of the Caribbean, it’s the turquoise seas, clean beaches, coral reefs teeming with fish, turtles and balmy breezes that come to mind.

For us, this paradise is what we call home. We depend upon its riches for sustenance and, often, to make a living. It is the origin of much of the pride we feel when we say we are from the Caribbean.

Increasingly however, the reality does not live up to expectations—we may arrive at the seashore to find it covered with sargassum, the water cloudy and brown, and the horizon covered in trash; the coral reefs may look faded and tired and with barely enough fish to count on one hand…

For visitors, what version of the paradise they may find is becoming unpredictable and some may never return, depending on their experience.

For locals, it’s a different matter—as seafood prices go up and children develop rashes after swimming in the ocean, and as houses flood after each storm and tourists turn their backs on the islands, the paradise is increasingly looking less idyllic.

Sounding a wake-up call to protect the reefs

More than 100 million people in the wider Caribbean region live on, or near the coast in a complex ecosystem with the highest number of marine species in the Atlantic Ocean.

Shallow-water coral reefs, mangroves, seagrass beds, lagoons, estuaries and beaches as well as coral banks and rocky outcrops in deep waters together make up the coral reef sub-ecosystem, the richest in biodiversity in the wider Caribbean region.

Almost 10 per cent of the world’s coral reefs are found in the Caribbean Sea and Gulf of Mexico, and 45 per cent of the fish species and 25 per cent of the coral species are found nowhere else in the world. With an area of 10,429 square kilometres of mangrove forest, the adjacent North Brazil Shelf has the highest mangrove coverage of any large marine ecosystem.

This wide ecosystem supports three of the region’s major fisheries—reef fish, spiny lobster and conch—and is the foundation of the region’s tourism industry. Coral reefs, mangroves and seagrass beds also play an important part in coastal and shoreline protection under normal sea conditions as well as during hurricanes and tropical storms.

A 2016 study by the World Bank put the economic value of the Caribbean Sea alone at US$407 billion per year. Yet this precious ecosystem is at the heart of competing economic and social demands as well as natural stresses and threats.

Pollution from activities on land and at sea degrades and destroys the reef.  Many once-abundant species are now threatened or endangered.

Hurricanes are becoming more frequent and more severe, resulting in great destruction and loss of lives, leaving both the coastline and local communities more vulnerable to future shocks.

A strategy to keep it pristine

Since 1981, UN Environment’s Caribbean Environment Programme has been working with the region’s national governments to better manage and use coastal and marine resources. 

Following the establishment, in 1983, of the Cartagena Convention—the only legally binding agreement for the protection of the Caribbean Sea—the programme has relentlessly worked to gain acceptance of, and agreement upon, three protocols or agreements to combat oil spills [the Oil Spills Protocol] coastal and marine biodiversity [the Specially Protected Areas and Wildlife Protocol] and pollution [the Land Based Sources of Marine Pollution Protocol] among its 28 member states and 14 territories.

As a result of the analysis of the wider Caribbean region conducted between 2007 and 2011 by the joint United Nations Development Programme and Global Environment Facility’s Caribbean Large Marine Ecosystem Project (2009–2014), the coral reef sub-ecosystem was given priority in a regional strategy to address transboundary problems that compromise the ability of the Caribbean Sea and the region’s living marine resources to support social and ecological well-being and resilience.

In the last two years, the Specially Protected Areas and Wildlife Protocol, together with the Caribbean and North Brazil Shelf Large Marine Ecosystems Project 2015–2020, published the Report on the State of Marine Habitats in the Wider Caribbean, which then became the basis for the Regional Strategy and Action Plan for the Valuation, Protection and/or Restoration of Key Marine Habitats in the Wider Caribbean 2021–2030. The strategy recommends a series of measures to support the people, economies and ecology of the region, targeting coral reefs, mangroves and seagrass beds in particular. 

Using an integrated approach, participating governments and stakeholders from academia, civil society, the private sector, and regional and global agencies are working together to enhance management and conservation of the coral reef sub-ecosystem in support of sustainable development.

UN Environment’s Caribbean Environment Programme, as Secretariat of the Specially Protected Areas and Wildlife Protocol, has been working to revamp the Caribbean Marine Protected Areas Managers Network and establish a regional wildlife enforcement network, in efforts to improve marine biodiversity management. Assisting the region and its countries in co-executing the strategic action plan is another important step in this direction. The Caribbean Environment Programme is driving the process, building the alliances needed to ensure the integrity of Caribbean coral reefs, seagrass beds and mangroves, in the hope to bring back the paradise we all expect.

The Perilous Migration of Birds through Cities

Meena Miriam Yust

How many birds flying into buildings die,

Thinking the glass reflection is the sky. —   with a nod to Kansas poet Madeleine Aaron

Bird migration is a wondrous and majestic phenomenon.  One may witness flocks of colorful songbirds sweeping the skies, geese gliding in a V-shape of beautiful symmetry, or a great hawk soaring above and diving for prey at 120 miles per hour.

About half of all birds in the world migrate, and even the smallest may travel remarkably long distances. Incredibly, the tiny hummingbird can fly nonstop 600 miles over the Gulf of Mexico. Some round-trip migrations can wind their way for as long as 44,000 miles.

Most songbirds migrate at night, and nocturnal travel makes their journey particularly perilous in light of human development. Birds face many obstacles along the way, including extreme weather events and lack of habitat. Yet, one particularly tragic and preventable peril remains: human-made structures.

Scientists estimate an astounding upper-level figure of 1 billion birds that die in the U.S. each year from building collisions. Making matters worse, 40 percent of the world’s bird species are already in decline. In the last decade alone, four birds became extinct and four more are “on the verge of extinction.”  Nearly one in five bird species in Europe is at risk of extinction

Artificial light from buildings draws migratory birds like a beckoning siren, luring them toward lit cities where skyscraper glass reflections are plentiful and deadly. What appear to be skies and trees turn out to be deceptive reflections, and as the birds glide toward the images, they slam into glass. Many are killed instantly, while some are seriously wounded.

Scientists at the Cornell Lab of Ornithology have investigated light pollution and bird migration patterns in major U.S. cities to determine where collision risks are highest. They report that the median light exposure to birds in cities is 24 times higher than the countrywide average. Chicago tops the list of dangerous U.S. cities for birds, followed by Houston and Dallas. This is true for both fall and spring migrations. Other dangerous metropolises include New York, Minneapolis, St. Louis and Los Angeles.

The central region of the U.S. happens to be a superhighway for bird migrations. Every spring and fall, over 5 million migrating birds comprised of 250 species pass over Chicago, where the city’s glass skyscrapers and artificial light become a death trap. Scientists from the Field Museum in Chicago have been counting dead birds at just one building (McCormick Place) since 1978. By 2002, the numbers had totaled 29,842 birds from 140 species. Chicago clearly has to be a major focus for conservation efforts during migration periods, as should the other hazardous cities identified in the study.

Another useful lesson from the Cornell study is one of timing, and this can help birds in many geographic regions of the U.S. Particularly crucial is the ability to pinpoint specifically when the birds face the greatest risks in each region. Fine-tuning the weeks when help is most needed can have a substantial impact on saving birds.

Researchers discovered that while a migration may continue over a six-month period, it “occurs in sporadic waves,” with the vast majority of birds passing through dangerous locales on just a few nights. Half of all migratory birds each season passed a metro location on approximately 7 to 10 nights during their migrations. This means helping birds, even for a period as short as a week, can have a significant impact. Really though, we must do more.

How Can We Lower the Rate of Bird Collisions?

For low-rises and high-rises, minimizing artificial window light is highly beneficial. This can be done by turning out the lights at night, drawing curtains and blinds, using a small lamp on a table rather than bright ceiling lights and introducing lights with motion sensors in office buildings.

Additionally, participating in Lights Out projects during peak migration times saves many birds. For the average reader, this is as simple as turning the lights out after 11 pm during fall and spring migration months. For building owners, minimizing exterior lighting is also essential. Lights Out programs are being organized in many major cities and have saved thousands of birds. A two-year study by the Field Museum using McCormick Place in Chicago found that turning off the lights resulted in an 83 percent reduction in bird window-collision deaths.

Chicago Bird Collision Monitors rescues injured birds and counts fatalities each morning during migration. Notably, they rescued an injured peregrine falcon (on the endangered list) that was restored to health and released. “We know that before all buildings were participating consistently in Lights Out, there was a foggy night in 2002 when many birds were migrating where a single building was reported to kill over a thousand birds in one evening,” said Annette Prince, the program’s director. “Chicago Bird Collision Monitors worked with buildings to get better participation in Lights Out and by 2004, saw 100 percent participation in light reduction so that subsequently we have never had a single building kill so many birds at once.” 

The Cornell Lab of Ornithology has a live bird migration map, so one can view in real time when birds are migrating through one’s locale and be cognizant of light pollution during peak days. It is important to note that turning lights out whenever possible is also beneficial outside of migration periods, as scientists have shown that substantial numbers of collisions can and do occur outside of migration periods, even in winter.  

Bird-friendly architecture for new construction is essential, as is mandatory legislation. Additionally, adding bird-safe architecture to green building certification standards is recommended by scientists. The extent to which architectural changes can affect bird collision incidence is illustrated by the recent renovation of New York’s Javits Center – a building previously responsible for the most bird deaths per year in New York. To help mitigate the problem, architects replaced dark-mirrored glass with glass that had a subtle fritted pattern, and also added a green roof for nesting. The project was a remarkable success, reducing bird collisions by 95 percent.  Other architectural strategies are installation of UV-coated glass, translucent glass and indented windows with shutters. Legislation requiring implementation of these strategies is crucial to saving birds from collisions.

Chicago proposed bird-friendly building legislation at the beginning of the year.  The ordinance would limit the percentage of transparent or reflective glass that can be used in new and renovated construction exteriors. Specifically, it would require that from the ground to 36 feet up, at least 95 percent of the exterior cannot be covered in glass, or must use glass containing frosting, etching or screens.  Nonessential exterior lighting would also be required to automatically shut off after 11 pm. Chicago’s legislation was introduced by Alderman Brian Hopkins and is supported by Bird Friendly Chicago. It is expected that real estate developers will oppose the bill. Michael Cornicelli, executive vice president of the Building Owners and Managers Association of Chicago, communicated that the portion of the bill requiring adoption of bird-friendly architecture to renovations of existing buildings would be “a potential sticking point.” San Francisco and Toronto already have bird-friendly legislation in place to serve as a model.

On a national level, U.S. Rep. Mike Quigley, a Democrat who is also a Chicago resident, has reintroduced the Bird-Safe Buildings Act (H.R. 919), which he has tried four times to pass since 2010. Dr. Christine Sheppard, director of American Bird Conservancy’s Glass Collisions Program, notes, “The legislation would help address one of the greatest human-caused threats to birds. Although this legislation is limited to federal buildings, it’s a very good start that could lead to more widespread applications of bird-friendly designs and use of bird-smart glass solutions.” 

When enacted, these bills will reduce bird collision deaths, and in the next few months, we will see how they fare.  

In the meantime, researchers recommend that residents take a few of the following precautions to help minimize window collisions: angling windows to reduce reflection, keeping indoor vegetation away from windows, installing netting, ultraviolet-reflecting glass or decals spaced closely together.  And of course, simply turning out the lights helps. 

These same strategies can be used in any city around the world where migratory birds traverse.  Collectively, we can reduce the incidence of bird collisions and help the many already threatened species to have a better chance of survival.

In the coming months, look to the sky and around you. Stop awhile and you will hear birdsong, more in the morning but also during the day; wee warblers with deceptively loud melodies, cardinals singing their sweet song, and if you look carefully you might catch a glimpse of a puff of bright yellow, the source of that surprising volume. These and others are growing families and enriching our lives before they prepare for the thousands of miles long autumn journey to their winter homes.
