Despite encouraging progress in several areas, the natural world is suffering badly and getting worse. Eight transformative changes are, therefore, urgently needed to ensure human wellbeing and save the planet, the UN warns in a major report.
The report comes as the COVID-19 pandemic challenges people to rethink their relationship with nature, and to consider the profound consequences to their own wellbeing and survival that can result from continued biodiversity loss and the degradation of ecosystems.
The Global Biodiversity Outlook 5 (GBO-5), published by the UN Convention on Biological Diversity (CBD), offers an authoritative overview of the state of nature. It is a final report card on progress against the 20 global biodiversity targets agreed in 2010 with a 2020 deadline, and offers lessons learned and best practices for getting on track.
“This flagship report underlines that ‘humanity stands at a crossroads with regard to the legacy we wish to leave to future generations,’” said CBD Executive Secretary, Elizabeth Maruma Mrema.
“Many good things are happening around the world and these should be celebrated and encouraged. Nevertheless, the rate of biodiversity loss is unprecedented in human history and pressures are intensifying. Earth’s living systems as a whole are being compromised. And the more humanity exploits nature in unsustainable ways and undermines its contributions to people, the more we undermine our own well-being, security and prosperity.”
“As nature degrades,” Ms. Mrema continued, “new opportunities emerge for the spread to humans and animals of devastating diseases like this year’s coronavirus. The window of time available is short, but the pandemic has also demonstrated that transformative changes are possible when they must be made.”
“The decisions and level of action we take now will have profound consequences — for good or ill — for all species, including ours.”
With respect to the Aichi Biodiversity Targets, set in 2010, the analysis based on the 6th set of national reports to the CBD and the latest scientific findings shows that seven of 60 “elements” — success criteria — within the 20 targets have been achieved and 38 show progress. In the case of 13 elements, no progress was made, or a move away from the target was indicated, and for two elements the level of progress is unknown. The report concludes that, overall, of the 20 targets, six of them (9, 11, 16, 17, 19 and 20) were partially achieved by the 2020 deadline.
“Now, we must accelerate and scale-up collaboration for nature-positive outcomes – conserving, restoring and using biodiversity fairly and sustainably. If we do not, biodiversity will continue to buckle under the weight of land- and sea-use change, overexploitation, climate change, pollution and invasive alien species. This will further damage human health, economies and societies – with particularly detrimental effects on indigenous peoples and local communities” said Inger Andersen Executive Director, UNEP.
“We know what needs to be done, what works and how we can achieve good results. If we build on what has already been achieved, and place biodiversity at the heart of all our policies and decisions – including in COVID-19 recovery packages – we can ensure a better future for our societies and the planet” she added.
By partially met, GBO5 refers to targets where at least one distinct element has been met. For example, the elements of Target 11 regarding the proportions of lands and seas protected was met, but the elements related to the quality of protected areas were not. Similarly, for Target 19, biodiversity knowledge has improved but it has not been widely shared or applied. For Target 20, official development assistance doubled but resources did not increase from all sources.
The national reports to the CBD offer evidence that the types of transitions needed moving forward are beginning; that virtually all countries are taking steps to protect biodiversity.
GBO5 cites several exemplary national actions and programmes, in the absence of which conditions would certainly be worse (extinctions would be higher for example).
In addition, for example, deforestation rates continue to fall, eradication of invasive alien species from islands is increasing, awareness of biodiversity appears to be increasing.
“The actions that have been taken need to be significantly scaled up, move from being project driven and become more systemic and broadened,” says Ms. Mrema. “Also, the gaps in national ambition and action need to be filled. The information in part III of GBO-5 is about doing this and provides examples of the types of actions that needed going forward.”
The report calls for a shift away from “business as usual” across a range of human activities. It outlines eight transitions that recognize the value of biodiversity, the need to restore the ecosystems on which all human activity depends, and the urgency of reducing the negative impacts of such activity:
- The land and forests transition: conserving intact ecosystems, restoring ecosystems, combatting and reversing degradation, and employing landscape level spatial planning to avoid, reduce and mitigate land-use change
- The sustainable agriculture transition: redesigning agricultural systems through agroecological and other innovative approaches to enhance productivity while minimizing negative impacts on biodiversity
- The sustainable food systems transition: enabling sustainable and healthy diets with a greater emphasis on a diversity of foods, mostly plant-based, and more moderate consumption of meat and fish, as well as dramatic cuts in the waste involved in food supply and consumption
- The sustainable fisheries and oceans transition: protecting and restoring marine and coastal ecosystems, rebuilding fisheries and managing aquaculture and other uses of the oceans to ensure sustainability, and to enhance food security and livelihoods
- The cities and infrastructure transition: deploying “green infrastructure” and making space for nature within built landscapes to improve the health and quality of life for citizens and to reduce the environmental footprint of cities and infrastructure
- The sustainable freshwater transition: an integrated approach guaranteeing the water flows required by nature and people, improving water quality, protecting critical habitats, controlling invasive species and safeguarding connectivity to allow the recovery of freshwater systems from mountains to coasts
- The sustainable climate action transition: employing nature-based solutions, alongside a rapid phase-out of fossil fuel use, to reduce the scale and impacts of climate change, while providing positive benefits for biodiversity and other sustainable development goals
- The biodiversity-inclusive One Health transition: managing ecosystems, including agricultural and urban ecosystems, as well as the use of wildlife, through an integrated approach, to promote healthy ecosystems and healthy people.
Cut methane emissions to avert global temperature rise
Methane emissions caused by human activity can be reduced by up to 45 per cent this decade, thus helping to keep global temperature rise to 1.5 degrees Celsius in line with the Paris Agreement on climate change, according to a UN-backed report published on Thursday.
The Global Methane Assessment outlines the benefits of mitigating methane, a key ingredient in smog, which include preventing some 260,000 premature deaths and 775,000 asthma-related hospital visits annually, as well as 25 million tonnes in crop losses.
The study is the work of the Climate and Clean Air Coalition (CCAC), a global partnership of governments and non-State partners, and the UN Environment Programme (UNEP).
“Cutting methane is the strongest lever we have to slow climate change over the next 25 years and complements necessary efforts to reduce carbon dioxide. The benefits to society, economies, and the environmental are numerous and far outweigh the cost”, said Inger Andersen, the UNEP Executive Director.
Methane is an extremely powerful greenhouse gas, responsible for around 30 per cent of warming since the pre-industrial era.
Most human-caused methane emissions come from three sectors: fossil fuels, such as oil and gas processing; landfills and waste; and agriculture, chiefly related to livestock.
Emissions ever increasing
The report underscores why international action is urgently needed as human-caused methane emissions are increasing faster than at any time since record keeping began in the 1980s.
Even with the COVID-19 pandemic causing an economic slowdown in 2020, which prevented another record year for carbon dioxide (CO2) emissions, data from the United States National Oceanic and Atmospheric Administration (NOAA) shows the amount of methane in the atmosphere reached record levels last year.
The good news
However, unlike CO2, which stays in the atmosphere for centuries, methane breaks down quickly and most is gone after a decade, meaning action can rapidly reduce the rate of global warming in the near-term.
Methane accounts for nearly one-fifth of global greenhouse gas emissions, according to Rick Duke, Senior Advisor to John Kerry, the US Special Presidential Envoy on Climate Change.
“The United States is committed to driving down methane emissions both at home and globally—through measures like research and development, standards to control fossil and landfill methane, and incentives to address agricultural methane”, he said.
Solutions readily available
The Assessment identifies readily available solutions that would reduce methane emissions by 30 per cent by 2030, mainly in the fossil fuel sector. Most, or around 60 per cent, are low cost and half have “negative costs”, meaning companies will make money from taking action.
So-called “mitigation potential” varies between countries and regions, according to the report. For example, whereas the largest potential in Europe and India is in the waste sector, in China it is from coal production and livestock, while in Africa it is from livestock followed by oil and gas.
“But targeted measures alone are not enough”, the partners warned. “Additional measures that do not specifically target methane, like a shift to renewable energy, residential and commercial energy efficiency, and a reduction in food loss and waste, can reduce methane emissions by a further 15 per cent by 2030.”
Drew Shindell, a Professor of Climate Science at Duke University in the USA, who chaired the assessment for the CCAC, said urgent steps must be taken to reduce methane emissions this decade.
“To achieve global climate goals, we must reduce methane emissions while also urgently reducing carbon dioxide emissions,” Dr Shindell said. “The good news is that most of the required actions bring not only climate benefits but also health and financial benefits, and all the technology needed is already available.”
Seven Key Principles for Implementing Net Zero
Meeting our shared goals for avoiding dangerous climate change requires a dramatic acceleration of progress towards clean growth and resilience. Over 120 countries have so far announced their intention to bring emissions to net zero by the middle of this century. As we look forward to COP26, this growing political consensus is a cause for optimism about the world’s ability to reach the goals of the Paris Agreement. A tremendous amount of work is now needed to turn ambitions into reality.
With that in mind, Canada, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Japan, the Netherlands, Poland, Portugal, the Slovak Republic, Spain, Sweden, Switzerland, the United Kingdom and the United States welcome the following Seven Key Principles for Implementing Net Zero, and we encourage the IEA Secretariat and Members to examine how the IEA, building on its key strengths, can best support the delivery of these principles, in close partnership with other relevant institutions:
Sustainable recoveries can provide a once-in-a-generation down payment toward net zero: As countries stimulate economies and build back after the Covid-19 pandemic, they also have an historic opportunity to jumpstart progress toward achieving net zero emissions. The IEA can further support governments to harness the transition to sustainable net zero energy systems as a driver of clean, sustainable growth and job creation.
Clear, ambitious and implementable net-zero-aligned roadmaps to 2030 and beyond are critical: Governments can increase international confidence in the transition by setting out national roadmaps for action over the next vital 10 years, which incorporate each country’s diverse circumstances and utilise a variety of low-carbon technologies and options to enhance steady implementation. The IEA can further support governments across the IEA family in the development of net-zero-aligned roadmaps to 2030 and beyond, and provide necessary guidance and assistance to facilitate implementation.
Transitions will go faster when learning is shared: A wide range of real-world implementation challenges are holding back transitions, including meeting the energy needs of underserved populations and improving safe and sustainable energy access for the poorest and most vulnerable groups. The IEA’s Clean Energy Transitions Programme is supporting governments across the IEA family to navigate the technical and economic transition risks and chart an actionable course towards a sustainable and inclusive energy system. Further enhancing mechanisms to share best practices, collaborate on technology, and provide targeted advice across the IEA family can help drive the pace of transition across the global energy system.
Net zero sectors and innovation are essential to achieve global net zero: Today’s early stage technologies will likely need to contribute almost half of the emissions reductions required to set the world on an ambitious path to net zero. The development and deployment at scale of a range of climate-neutral energy technologies, combined with energy efficiency, can enable rapid, sustainable and deep energy transitions across all major energy use sectors – many of which involve complex value chains that cross national boundaries. Stronger, consolidated public-private mechanisms for international coordination are needed to accelerate innovation and deployment within sectors. The IEA can further enhance and improve its analysis of innovation and sector decarbonisation, and promote joint strategies and approaches across the IEA family, including coordination with other relevant international fora.
Mobilising, tracking and benchmarking public and private investment can be the fuel to achieve net zero: There is an urgent need to shift gears on climate-neutral energy investment to put the world on track for net zero. By 2030, the amount of investment required in electricity (generation and grid/storage) needs to rise to more than $1.6 trillion per year to be on track for net zero emissions by 2050. Major international efforts are required to increase capital flows for climate neutral energy in emerging markets and developing economies. Public and private sector actors need to be brought together to create the necessary enabling environments to further catalyse sustainable and socially acceptable energy investment. The IEA can enhance its provision of analysis and practical guidance to both governments and the finance community, including through partnerships with other relevant organisations.
People-centred transitions are morally required and politically necessary: As countries seek to advance their shifts to clean energy technologies, the success of these efforts will rest on enabling citizens to benefit from transition opportunities and to navigate disruptions. This includes social, environmental and economic impacts on individuals and communities, as well as issues of affordability and fairness. A focus on training and skills development to equip all citizens to participate in the net zero economy is also critical. Governments should continue to share best practices and, where useful, explore and step up new ways of sharing best practices for designing climate-neutral energy policies that are people-centred and inclusive, including as part of the IEA’s Global Commission on People-Centred Clean Energy Transitions.
Net zero energy systems also need to be sustainable, secure, affordable and resilient: Maintaining energy security through transitions is critical. Governments, companies and other key actors need to both anticipate and manage existing and new energy security challenges, including ensuring uninterrupted flow of energy, even as variable power sources increase. This will require ensuring a diverse, sustainable and socially acceptable clean energy and technology mix; making best use of existing infrastructure; and addressing emerging challenges such as climate resilience, cyber risks and the availability and security of critical minerals. Governments should work together to analyse where new mechanisms can contribute to further strengthening the security and resilience of the global energy system alongside a swift net zero transition, which can be underpinned by the IEA’s provision of analytic expertise, best practice and efficient security mechanisms.
Being united by the high level of their ambitions, countries at all stages of development will need to determine their own unique path to implementing net zero according to the diversity of national circumstances and wide range of technologies.
Collaborative Partnership on Forests calls for halt to deforestation
A group of 15 international organizations working on forestry today issued a joint statement highlighting the need to halt the destruction of the world’s forests.
The Collaborative Partnership on Forests (CPF) comprises UN agencies including the UN Environment Programme, the Food and Agriculture Organization of the United Nations (FAO), the UN Development Programme, the World Bank Group, and the four Rio Conventions.
In the joint statement released on the sidelines of the 16th Session of the UN Forum on Forests at UN Headquarters, the CPF outlined the impacts of deforestation as well as the opportunities and actions required to reverse it.
“Forests are a source of sustainable livelihoods, prosperity, and resilience, and it is incumbent upon all of us in the forest sector to work together to halt deforestation and increase the world’s forest area,” said Mette Løyche Wilkie, Chair of the Collaborative Partnership on Forests and Director, Forestry Division, FAO. “Today we affirm our collective commitment to support the call of UN Secretary-General António Guterres to turn the tide on deforestation.”
Deforestation and forest degradation continue at alarming rates, and are increasing in Africa. Since 1990, an estimated 420 million hectares of forest has been lost through deforestation globally, and 10 million hectares continues to be lost each year.
Deforestation and other land-use activities meanwhile account for 11 percent of global greenhouse gas emissions.
“To deliver on the Paris Agreement we must utilize the full potential of forests,” said Susan Gardner, Director, Ecosystems Division at UN Environment Programme..
The CPF statement outlines how the COVID-19 pandemic has placed additional pressure on forest resources and may result in a significant increase in deforestation. Healthy forests are essential to building back better and are also key in decreasing the risk of future zoonotic diseases, according to the statement.
The CPF sets out the challenges and the opportunities involved in halting deforestation, noting that it needs action beyond the forest sector – including by transforming agriculture and food systems to address the main driver of deforestation: the conversion of forests to agricultural land.
“2021 can be the year to make peace with nature if we increase ambition and identify opportunities for quantum shifts in scale of funding and result,” said Gardner.
“Feeding a growing world population and halting or even reversing deforestation are not mutually exclusive,” said Wilkie. “We can achieve both through a range of actions, including more balanced land-use planning, restoring the productivity of degraded agricultural lands, stepping up public and private sector commitments to zero deforestation, and reducing food loss and waste.”
While important public and private commitments to deforestation have been made, the CPF explains that implementation is lagging and needs to be accelerated if the goals are to be met. Progress on legal timber production and trade and strong forest governance are equally critical.
Ending deforestation is essential to confront the “quadruple planetary emergency”, of a climate crisis, a nature crisis, an inequality crisis and a global health crisis, according to the CPF statement.
The statement aims to build momentum for forests ahead of the upcoming launch of the United Nations Decade on Ecosystem Restoration on World Environment Day (5 June) and the UN Climate Conference (COP 26) in Glasgow later this year.
The CPF’s mission is to promote sustainable management of all types of forests and to strengthen long-term political commitment to this end. The Partnership is the driving force for the international forest agenda, providing technical and policy guidance and driving a coherent effort to meet global forest goals.
