Climate action cannot focus only on carbon dioxide. Governments and energy companies have major opportunities to reduce methane emissions, which provides the most impactful way to limit near-term climate change, the International Energy Agency said in a new report released today.
Methane is responsible for around 30% of the global rise in temperatures to date. Rapid steps to tackle methane emissions from oil, gas and coal operations would have immediate impacts because of the potent effect of methane on global warming and the large scope for cost-effective actions, according to the report, Curtailing methane emissions from fossil fuel operations: Pathways to a 75% cut by 2030.
Fossil fuel operations globally emitted close to 120 million tonnes of methane in 2020, nearly one-third of all methane emissions from human activity. Much of these emissions are simply leakage along the production and supply chain that operators fail to capture or avert. There are cost-effective ways to limit these emissions, especially in the oil and gas sector. The IEA estimates that more than 70% of current emissions from oil and gas operations are technically feasible to prevent and around 45% could typically be avoided at no net cost because the value of the captured gas is higher than the cost of the abatement measure. This share would be much higher at the moment, given the record highs in natural gas prices.
The report provides crucial insights and guidance for governments, regulators and the energy industry in the lead-up to the COP26 Climate Change Conference and beyond. Building on the estimates of emissions and options for addressing them in the IEA Methane Tracker and Regulatory Roadmap and Toolkit, the report identifies and quantifies a range of measures, including policy and regulatory actions, voluntary industry initiatives, and improvements in emissions measurement and reporting.
“At a time when we are constantly being reminded of the damaging effects of climate change, it is inexcusable that massive amounts of methane continue to be allowed to just seep into the air from fossil fuel operations,’’ said Fatih Birol, the IEA Executive Director. “These emissions are avoidable, the solutions are proven and even profitable in many cases. And the benefits in terms of avoided near-term warming are huge. I welcome the renewed impetus behind this issue with the Global Methane Pledge, announced by the European Union and the United States, and urge all countries and companies to step up their actions. ”
Quick action is needed because eventual declines in demand for fossil fuels alone will not achieve rapid enough reductions of methane emissions to forestall the worst effects of climate change. In the IEA’s Roadmap to Net Zero Emissions by 2050, methane emissions from fossil fuel operations fall by around 75% between 2020 and 2030. About one-third of this decline is a result of an overall reduction in fossil fuel consumption, but the larger share comes from measures and technologies aimed at reducing emissions in existing fields, pipelines and mines.
The new Global Methane Pledge calls for at least a 30% reduction in global methane emissions from human activity by 2030. If the world achieves the 75% cut in methane from fossil fuel operations as described in the new IEA report, this would lower total human-caused methane emissions by around 25%, and so would go a long way to achieving the aim of the Global Methane Pledge.
Multiple jurisdictions around the world have already employed well-established policy tools, including leak detection and repair requirements, technology standards and a ban on non-emergency flaring and venting. Some countries have included methane alongside other greenhouse gases in their national net zero pledges, while others have made more targeted announcements.
These governments could also leverage their buying power to incentivise other countries to step up their measures against emissions, given that more than 40% of the oil and gas produced in countries without strong methane commitments is exported for consumption in countries that do have such commitments.
Company initiatives play an important role in tackling emissions, especially when leading companies act to spread best practices across the industry. Growing transparency on the sources and magnitude of methane emissions is also set to play an important role, supported by promising developments in monitoring technologies, notably from satellites, and the establishment of a common framework for measuring and reporting emissions. To achieve rapid reductions in methane emissions, governments, companies and other stakeholders must all work to build a larger coalition of actors committed to this effort.
‘No time to lose’ curbing greenhouse gases
Last year, heat-trapping greenhouse gases reached a new record, surging above the planet’s 2011-2020 average, and has continued in 2021, according to a new report published on Monday by the UN weather agency.
The World Meteorological Organization (WMO) Greenhouse Gas Bulletin contains a “stark, scientific message” for climate change negotiations at the upcoming UN climate conference, known as COP26, in Glasgow, said Petteri Taalas, head of the UN agency.
“At the current rate of increase in greenhouse gas concentrations, we will see a temperature increase by the end of this century far in excess of the Paris Agreement targets of 1.5 to 2 degrees Celsius above pre-industrial levels”, he explained. “We are way off track.”
Concentration of carbon dioxide (CO2) in 2020 was 149 per cent above the pre-industrial level; methane, 262 per cent; and nitrous oxide, 123 per cent, compared to the point when human activitity began to be a destabilizing factor.
And although the coronavirus-driven economic slowdown sparked a temporary decline in new emissions, it has had no discernible impact on the atmospheric levels of greenhouse gases or their growth rates.
As emissions continue, so too will rising global temperatures, the report maintained.
Moreover, given the long life of CO2, the current temperature level will persist for decades, even if emissions are rapidly reduced to net zero.
From intense heat and rainfall to sea-level rise and ocean acidification, rising temperatures will be accompanied by more weather extremes – all with far-reaching socioeconomic impacts.
“The last time the Earth experienced a comparable concentration of CO2 was three to five million years ago, when the temperature was 2-3°C warmer and sea level was 10-20 meters higher than now”, stated the WMO chief. “But there weren’t 7.8 billion people then”, he reminded.
Roughly half of today’s human-emitted CO2 remains in the atmosphere and the other half is absorbed by oceans and land ecosystems, the Bulletin flagged.
At the same time, the capacity of land ecosystems and oceans to absorb emissions may become a less effective buffer against temperature increases in the future.
Meanwhile, many countries are currently setting carbon neutral targets amidst the hope that COP26 will see a dramatic increase in commitments.
“We need to transform our commitment into action that will have an impact of the gases that drive climate change. We need to revisit our industrial, energy and transport systems and whole way of life”, said the WMO official.
“The needed changes are economically affordable and technically possible“, he assured. “There is no time to lose”.
CO2 is the single most important greenhouse gas and has “major negative repercussions for our daily lives and well-being, for the state of our planet and for the future of our children and grandchildren”, argued the WMO chief.
Carbon sinks are vital regulators of climate change because they remove one-quarter of the CO2 that humans release into the atmosphere.
Nitrous Oxide is both a powerful greenhouse gas and ozone depleting chemical that is emitted into the atmosphere from both natural and anthropogenic sources, including oceans, soils, biomass burning, fertilizer use and various industrial processes.
Multiple co-benefits of reducing methane, whose gas remains in the atmosphere for about a decade, could support the Paris Agreement and help to reach many Sustainable Development Goals (SDGs), said the Bulletin.
Landmark decision gives legal teeth to protect environmental defenders
A 46-strong group of countries across the wider European region has agreed to establish a new legally binding mechanism that would protect environmental defenders, the UN Economic Commission for Europe (UNECE) said on Friday.
“I remain deeply concerned by the targeting of environmental activists”, said Secretary-General Antonio Guterres, welcoming the rapid response mechanism as “an important contribution to help advance my Call to Action for Human Rights”.
The agreement will delegate setting up the new mechanism to the United Nations, or another international body.
As the first ever internationally-agreed tool to safeguard environmental defenders, it marks an important step in upholding the universal right to a clean, healthy and sustainable environment – as recognized by the Human Rights Council earlier this month.
“Twenty years ago, the Aarhus Convention entered into force, bridging the gap between human and environmental rights.
Today, as the devastating effects of climate change continue to ravage the world, the Convention’s core purpose – of allowing people to protect their wellbeing and that of future generations – has never been more critical”, spelled out the UN chief.
A protective eye
The agreement to establish the mechanism was adopted on Thursday by the Meeting of the Parties to the Convention on Access to Information, Public Participation in Decision-Making and Access to Justice in Environmental Matters, known as the Aarhus Convention.
“This landmark decision is a clear signal to environmental defenders that they will not be left unprotected”, said UNECE chief Olga Algayerova.
“It demonstrates a new level of commitment to upholding the public’s rights under the Aarhus Convention, as well as Parties’ willingness to respond effectively to grave and real-time challenges seen in the Convention’s implementation on the ground”.
Whether it is groups protesting the construction of a dangerous dam or individuals speaking out against harmful agricultural practices in their local community, these activists are vital to environmental preservation across the globe, said the UNECE.
The Aarhus Convention ensures that those exercising their rights in conformity with the provisions of the Convention shall not be penalized, persecuted or harassed in any way for their involvement.
As such, the mechanism will establish a Special Rapporteur – or independent rights expert – who will quickly respond to alleged violations and take measures to protect those experiencing or under imminent threat of penalization, persecution, or harassment for seeking to exercise their rights under the Convention.
As time is of the essence to buttress the safety of environmental defenders, any member of the public, secretariat or Party to the Aarhus Convention, will be able to submit a confidential complaint to the Special Rapporteur, even before other legal remedies have been exhausted.
Although it is crucial for environmental defenders to confidently exercise their rights, cases have been reported in which instead, they face being fired, heavy fines, criminalization, detention, violence, and even death.
Moreover, incidents of harassment and violence against environmental defenders are far from uncommon.
A report to the Human Rights Council by Mary Lawlor, Special Rapporteur on the situation of human rights defenders, found that one-in-two human rights defenders who were killed in 2019 had been working with communities around issues of land, environment, impacts of business activities, poverty and rights of indigenous peoples, Afrodescendants and other minorities.
Since January 2017, among the Parties to the Aarhus Convention, incidents of persecution, penalization and harassment of environmental defenders have been reported in 16 countries.
In contrast to current existing initiatives, which mainly rely on applying political pressure through the media, the Aarhus Convention’s rapid response mechanism will be built on a binding legal framework, giving it much greater powers to act.
Plastic pollution on course to double by 2030
Plastic pollution in oceans and other bodies of water continues to grow sharply and could more than double by 2030, according to an assessment released on Thursday by the UN Environment Programme (UNEP).
The report highlights dire consequences for health, the economy, biodiversity and the climate. It also says a drastic reduction in unnecessary, avoidable and problematic plastic, is crucial to addressing the global pollution crisis overall.
To help reduce plastic waste at the needed scale, it proposes an accelerated transition from fossil fuels to renewable energies, the removal of subsidies and a shift towards more circular approaches towards reduction.
Titled From Pollution to Solution: a global assessment of marine litter and plastic pollution, the report shows that there is a growing threat, across all ecosystems, from source to sea.
Solutions to hand
But it also shows that there is the know-how to reverse the mounting crisis, provided the political will is there, and urgent action is taken.
The document is being released 10 days ahead of the start of the crucial UN Climate Conference, COP26, stressing that plastics are a climate problem as well.
For example, in 2015, greenhouse gas emissions from plastics were 1.7 gigatonnes of CO2 equivalent; by 2050, they’re projected to increase to approximately 6.5 gigatonnes. That number represents 15 per cent of the whole global carbon budget – the amount of greenhouse gas that can be emitted, while still keeping warming within the Paris Agreement goals.
Recycling not enough
Addressing solutions to the problem, the authors pour cold water on the chances of recycling our way out of the plastic pollution crisis.
They also warn against damaging alternatives, such as bio-based or biodegradable plastics, which currently pose a threat similar to conventional plastics.
The report looks at critical market failures, such as the low price of virgin fossil fuel feedstocks (any renewable biological material that can be used directly as a fuel) compared to recycled materials, disjointed efforts in informal and formal plastic waste management, and the lack of consensus on global solutions.
Instead, the assessment calls for the immediate reduction in plastic production and consumption, and encourages a transformation across the whole value chain.
It also asks for investments in far more robust and effective monitoring systems to identify the sources, scale and fate of plastic. Ultimately, a shift to circular approaches and more alternatives are necessary.
Making the case for change
For the Executive Director of UNEP, Inger Andersen, this assessment “provides the strongest scientific argument to date for the urgency to act, and for collective action to protect and restore our oceans, from source to sea.”
She said that a major concern is what happens with breakdown products, such as microplastics and chemical additives, which are known to be toxic and hazardous to human and wildlife health and ecosystems.
“The speed at which ocean plastic pollution is capturing public attention is encouraging. It is vital that we use this momentum to focus on the opportunities for a clean, healthy and resilient ocean”, Ms. Andersen argued.
Currently, plastic accounts for 85 per cent of all marine litter.
By 2040, it will nearly triple, adding 23-37 million metric tons of waste into the ocean per year. This means about 50kg of plastic per meter of coastline.
Because of this, all marine life, from plankton and shellfish; to birds, turtles and mammals; faces the grave risk of toxification, behavioral disorder, starvation and suffocation.
The human body is similarly vulnerable. Plastics are ingested through seafood, drinks and even common salt. They also penetrate the skin and are inhaled when suspended in the air.
In water sources, this type of pollution can cause hormonal changes, developmental disorders, reproductive abnormalities and even cancer.
According to the report, there are also significant consequences for the global economy.
Globally, when accounting for impacts on tourism, fisheries and aquaculture, together with the price of projects such as clean-ups, the costs were estimated to be six to 19 billion dollars per year, during 2018.
By 2040, there could be a $100 billion annual financial risk for businesses if governments require them to cover waste management costs. It can also lead to a rise in illegal domestic and international waste disposal.
The report will inform discussions at the UN Environment Assembly in 2022, where countries will come together to decide a way forward for more global cooperation.
