Homing in on methane emissions from the oil and gas industry

Published

on

The United Nations Environment Programme (UNEP) stands with those suffering from the COVID-19 pandemic. UNEP is responding in a number of ways, including by supproting global efforts to protect biodiversity, to put an end to the illegal trade in wildlife, to safeguard the handling of chemicals and waste and to promote economic recovery plans that take nature and the climate emergency into account. This article is one of several highlighting UNEP’s duty to help nations build back better after the pandemic to increase resilience to future crises.

With scientists saying the polar ice caps are melting six times faster than in the 1990s there is an urgent need to reduce greenhouse gas emissions as quickly as possible to prevent catastrophic sea-level rise.

Methane is a powerful short-lived climate pollutant emitted by oil and gas extraction, livestock, wetlands, and landfills.

According to The Climate and Clean Air Coalition, methane’s global warming potential is 84 times that of carbon dioxide (CO2) over a 20 year timeframe. Methane has a big impact on climate change in the near-term which means that targeting it is an important tool in fighting a warming planet.

Currently there is uncertainty about the quantity of methane emitted from offshore global oil and gas infrastructure.

The Climate and Clean Air Coalition supported research on methane emissions from oil and gas platforms in the Gulf of Mexico which was published on 9 March 2020 in Environmental Science and Technology.

One surprising conclusion is that the largest emitters were in shallower waters. 

Part of the  Oil and Gas Methane Science Studies, the study presents a novel method for measuring methane emissions that can be applied to offshore facilities across the globe.

There is a particular dearth of data when it comes to measurements of oil rigs in the ocean—in fact there are none in the Gulf of Mexico. In the United States, the majority of offshore oil and natural gas is drilled in the Gulf of Mexico where thousands of platforms are responsible for about 16 percent of the country’s crude oil production.

The study sheds light on two important characteristics of offshore emissions that should aid mitigation efforts: 1) the existence of a skewed distribution—a few sites account for a large proportion of total emissions, and 2) there are different emissions patterns between shallow and deep water facilities.

Each study targets different geographic regions, including urban areas in Europe, the North Sea, and parts of Australia, as well as different segments of the oil and gas supply chain. These studies will be done from aeroplanes, from boats, and on land.

So far, the Environmental Defense Fund, the European Commission, and the companies of the Oil and Gas Climate Initiative have committed US$7.2 million to this research. The Coalition, which calls 69 governments and many more civil society organizations members, together with the United Nations Environment Programme (UNEP), will then work with governments relevant to each study, linking policy and action to help address methane emissions.

The Coalition’s Oil and Gas Methane Partnership is also helping companies systematically manage their methane emissions from upstream oil and gas operations.

With better data, oil and gas companies can more effectively prioritize their work to reduce methane emissions and governments can more effectively target policies that aim to do the same. 

Where do the leaks occur?

Methane leaks occur at various stages of the supply chain, including when it is extracted, processed, and transported. Often, major leaks are due to faulty maintenance which can, in some cases, be relatively easily addressed if the source is identified—such as a loose screw or a valve. Preventing gas leakage during transmission and distribution could reduce emissions from coal mining and the oil and gas sector by over 65 percent

There is increasing evidence that previous estimates of methane emissions from the oil and gas industry have been underestimated. One study recently published in Nature shows that it could be as much as by 25-40 percent.

Research was published by a team of Dutch scientists last year on how accidents in the oil and gas sector can release large amounts of methane in short periods of time. In one natural gas well in Ohio in the United States in February 2018, a single blowout released enough methane to rival a significant percentage of the man-made emissions of several European countries over an entire year.

UNEA-5 ends with clear message: act now to tackle planetary crises

Published

on

The virtual Fifth Session of the UN Environment Assembly ended on Tuesday with a clear message: our fragile planet needs more and it needs it now. More action, more cooperation, more finance, more ambition and more sustained commitment to tackle environmental crises and rebuild societies ravaged by the global pandemic.

At this unprecedented virtual session153 countries registered and connected online along with civil society and other stakeholders, showing the commitment of stakeholders to tackle pressing issues of environmental degradation even during the COVID-19 crisis.

Participants were left in no doubt that 2021 marks a critical turning point if the world wants to secure a future where people and planet can thrive together.

UNEP’s Executive Director Inger Andersen described the cost of inaction in remarks to Tuesday’s Leadership Dialogue.

“Unless we take action, future generations stand to inherit a hothouse planet with more carbon in the atmosphere than in 800,000 years. Unless we take action, future generations will live in sinking cities. From Basra to Lagos. From Mumbai to Houston. Unless we take action, future generations will be lucky if they can spot a black rhino. And unless we take action, future generations will have to live with our toxic waste – which every year is enough to fill 125,000 Olympic size swimming pools,” she said.

Indian environmental activist Afroz Shah, who has been honoured by UNEP as a Champion of the Earth, told the delegates that the time for talking was over and that collaboration was needed to redress the planetary balance.

“The problem is our rights are weighing too heavy on the rights of the other species. This delicate balance will have to tilt in the favour of other species and that is the key,” he said.

During two days of online meetings and presentations, many Member States expressed profound concern at the triple planetary crises of climate change, nature loss and pollution, noting that the COVID-19 pandemic had exacerbated existing problems and threatened efforts to achieve the Sustainable Development Goals.

“We will face recurring risks of pandemics in the future if we maintain our current unsustainable patterns in our interactions with nature,” said Sveinung Rotevatn, President of UNEA-5. “I believe we have discovered during this time of crisis just how much our health and wellbeing depends upon nature and the solutions that nature provides.”

President Uhuru Kenyatta of Kenya, which hosts UNEP’s headquarters in Nairobi, also spoke of the need to act swiftly.

“It is increasingly evident that environmental crises are part of the journey ahead. Wildfires, hurricanes, high temperature records, unprecedented winter chills, plagues of locusts, floods and droughts, have become so commonplace that they do not always make the headlines,” he told the Assembly.

“These increasing adverse weather and climatic occurrences sound a warning bell that calls on us to attend to the three planetary crises that threaten our collective future: the climate crisis, the biodiversity and nature crisis, and the pollution and waste crisis.”

The situation is dire but there are reasons to hope. Member States expressed support for a green post-pandemic recovery that leaves no one behind and also protects and renews the fragile natural world, with many noting that the health of nature and human health are inextricably linked, with the nature crisis also tied to the climate and pollution crises.

The green recovery should put the world on a pathway towards a low carbon, resilient and inclusive post-pandemic world. It should invest in the transition to a circular economy to achieve sustainable consumption and production and make full use of the role that nature-based solutions can offer to address climate change, nature loss and pollution. 

Over two days, UNEA-5 saw a global effort on resource efficiency and the circular economy; a recognition of the importance of financing and emissions reductions; and an exploration of big data as a tool for changeAhead of the Assembly, science and business leaders also gathered virtually for the UN Science-Policy-Business Forum to discuss the role of business in addressing the triple planetary crises.

Member States committed to work together and also outlined actions already taken nationally, such as efforts to protect mangroves, peatlands and forests or to tackle pollution and waste, including single use plastics. Representatives from youth groups addressed delegates, demanding action and a voice at the table.

The Assembly endorsed a final statement warning that “more than ever that human health and wellbeing are dependent upon nature and the solutions it provides, and we are aware that we shall face recurring risks of future pandemics if we maintain our current unsustainable patterns in our interactions with nature.”

Despite the gravity of the challenges facing humanity and the planet, the meeting also heard messages of inspiration.

“We have gathered here as ambassadors of hope and architects of a new paradigm and our work together and in harmony with nature will ensure our ultimate victory,” Ghanaian musician and UNEP Regional Goodwill Ambassador Rocky Dawuni told delegates.

A roadmap to a better, more sustainable future was provided by UNEP’s Making Peace with Nature report, which was launched by the UN Secretary-General Antonio Guterres last week. It shows clearly that the earth’s environmental emergencies must be addressed together to achieve sustainability. This means tackling the red thread that binds these emergencies together – unsustainable consumption and production. The report suggests concrete actions for different sectors – from governments to civil society to businesses – to address the planetary crisis.

UNEP will drive the radical change to an era of action. Delegates to UNEA-5 approved its Medium-Term Strategy 2022-25, programme of work and budget, enabling it to work harder for an end to unsustainable consumption and production.

“The strategy is about transforming how UNEP operates and engages with Member States, UN agencies, the private sector, civil society and youth groups, so we can go harder, faster, stronger,” said UNEP‘s Andersen. “This strategy is about providing science and know-how to governments. The strategy is also about collective, whole-of-society action – moving us outside ministries of environment to drive action.”

UNEA-5 also marked the start of a period of reflection and celebration to mark the creation of UNEP 50 years ago.

The second part of UNEA-5 is scheduled to take place in February 2022 with hopes that delegates will be able to meet in person with a richer and fuller agenda.

Between now and then, the world needs to see enhanced ambitions on cutting greenhouse gases, a strong post-2020 framework for protecting our precious biodiversity and a commitment to managing chemicals and tackling plastic pollution.

This Assembly marked the start of a year of critical meetings on all these issues, with Member States gathering later this year, notably at UN Biodiversity Conference in Kunming, China, where nations will address species and ecosystem loss, and then at the UN Climate Conference, known as COP26, in Glasgow when countries are expected to come forward with more ambitious commitments on cutting greenhouse gas emissions.

As the UN Secretary-General said in his speech to UNEA-5: “To a large degree, the viability of humanity on this planet depends on your efforts. With leadership, determination and commitment to future generations, I am convinced we can provide a healthy planet for all humanity to not just survive, but to thrive.”

At the end of the Assembly, UNEP’s Inger Andersen said UNEA 5.1 was extremely successful.

“The science is clear. We have to change our ways and we have to be sure that 2021 is that turning point,” she said. “UNEA 5.1, in spite of the pandemic and meeting virtually, managed to be the first step of that journey.”

Georgia’s Blue Economy Can Be a Vehicle for Accelerating Climate Change Adaptation

Published

on

Greening the Coast and Blueing the Sea for a Resilient Georgiaa virtual event on climate change and marine pollution – was held today with the cooperation of the World Bank, the Organization of the Black Sea Economic Cooperation (BSEC) andthe Government of Georgia.

The event was focused on the findings and recommendations of two recent World Bank reports: Impacts of Climate Change on Georgia’s Coastal Zone: Vulnerability Assessment and Adaptation Options and The Cost of Coastal Zone Degradation in Georgia: A Tool for the Coastal Zone Adaptation and the Nationally Determined Contributions.

The reports identify key climate risks and vulnerabilities and the costs of environmental degradation of the coastal zone due to pollution, flooding, coastal erosion, and agricultural soil and forest degradation. Climate adaptation through resilient use of water resources and bringing back tourism to coastal areas after the COVID-19 pandemic are among the recommended priority coastal adaptation interventions.

“Georgia is committed to making its coastal and marine spaces and tourism more resilient, and our Black Sea less polluted,” said Nino Tandilashvili, Deputy Minister of Environmental Protection and Agriculture of Georgia.

With the World Bank’s global knowledge and support, Georgia is well positioned to enter a new frontier with its climate pledges under the 2015 Paris Agreement. In addition to climate adaptation measures in its coastal zone, transition to a more sustainable Blue Economy can become a public policy goal that can support Georgia’s EU integration agenda and its national development objectives, while preventing environmental degradation and ecological imbalances in the use of coastal and marine resources.

“While the reports seek to raise the level of urgency needed to reduce the impact of climate change on the coastal zone and the escalating cost of inaction, it is not too late for action to ensure that the coastline of the Black Sea of Georgia adapts to climate change. Overall, the blue economy is vital for the social-economic development of Georgia and other countries across the region,” said Sebastian Molineus, World Bank Regional Director for the South Caucasus.

Today’s event also initiated consultations on Blueing the Black Sea, a World Bank and BSEC supported new regional initiative to tackle marine pollution and catalyze Blue Economy investments in the Black Sea region. Recognizing the critical importance that environmental rehabilitation of the Black Sea has for the entire region, the World Bank supports Georgia, as well as other countries of the region, in their collaboration for effective pollution prevention, reduction, and control in the Black Sea.

“Transboundary pollution challenges require regional solutions,” noted Steven Schonberger, World Bank Sustainable Development Regional Director. “However, the regional goals have to translate into national investments that promote economic growth. Any country tackling pollution alone cannot guarantee a desirable quality of the sea water in a closed ecosystem such as the Black Sea. Considering this common ecosystem, collaboration at the regional level is essential.”

The Blueing the Black Sea consultations contribute to strengthened national and regional dialogue to address marine pollution and provide Georgia with a valuable opportunity to integrate the Black Sea into the country’s strategies for climate adaptation and mitigation.

Public-private partnerships could play key role in combatting deforestation

Published

on

As environmental leaders and change makers meet virtually for the Fifth Session of the United Nations Environment Assembly (UNEA)  in February 2021, the issue of deforestation has been central to their discussions.

“There can be no conversation on climate change without including forests and deforestation,” said Gabriel Labbate, a forestry expert with the United Nations Programme on Reducing Emissions from Deforestation and Forest Degradation (UN-REDD).   “It is fundamental in the fight against the environmental emergency that faces us.”

Forests and woodlands are important stores of planet-warming carbon dioxide, soaking up 30 per cent of emissions from industry and fossil fuels. Their role in capturing and storing carbon is critical to mitigating the risks that climate change poses to the world’s food systems.

But every year, the world loses 7 million hectares of forests, an area the size of Portugal. Globally, primary forest area has fallen by over 80 million hectares since 1990, found the hallmark State of the World’s Forests report, produced by the United Nations Environment Programme (UNEP) and the Food and Agriculture Organisation (FAO). Today, forest fires, pests, diseases, invasive species, drought and extreme weather events put at least another 100 million hectares at risk.

At the UN Environment Assembly, experts discussed the Green Gigaton Challenge, an ambitious public-private partnership backed by the United Nations Environment Programme (UNEP). It aims to catalyse funds for initiatives to combat deforestation, with the target of reducing 1 gigaton (or 1 billion metric tonnes) of emissions by 2025.

The challenge channels public and private sector finance into efforts led by national and subnational governments to halt deforestation, while helping companies support their internal emissions reductions with the purchase of carbon credits. It advocates using nature-based solutions, such as replanting and restoring tropical forests, to reduce emissions. As well as cutting emissions, forests increase biodiversity and regulate water, offering a rounded environmental solution.

“Reducing emissions by 1 gigaton is the same as taking 80 per cent of all cars off the roads in the United States. It has a huge impact and the potential to deliver lasting environmental change. As countries look to rebuild their economies in the wake of COVID-19, 2021 can be the year we make a quantum shift in scale, funding and results,” said Niklas Hagelberg, Coordinator of UNEP’s climate change programme.

At the Green Gigaton Challenge event, participants – who included Ministers of the Environment from various countries – discussed how private sector funding can jump-start forest-based solutions to climate change. Key to this is getting large corporations to understand how reforesting can help them meet their emissions reduction targets in a cost-effective way.

“We see private sector commitment growing and this is crucial in reducing emissions,” said Tim Christophersen, a UNEP ecosystems expert. “2021 provides a unique opportunity to make forests a real pillar of climate mitigation efforts. We will need to send clear and consistent policy signals to ensure this emerging market will be useful and can grow.”

The Green Gigaton Challenge is measurable, and financing can be results-based, meaning funds are released as targets are met. This results in more resources allocated as it gives donors, both private and public, peace of mind that they are getting what they pay for.

Initiatives like this are a step towards reducing global warming. The past decade was the hottest in human history and experts say the planet is on pace for in excess of 3°C of warming, a figure that could have catastrophic consequences.

UNEP is at the forefront of efforts to meet the targets of the Paris Agreement, namely keeping the global temperature rise to well below 2°C, and preferably to 1.5°C, compared to pre-industrial levels.

To this end, UNEP has developed a Six-Sector Solution to cutting emissions. The solution provides a roadmap to how emissions can be reduced across sectors in order to meet the annual 29-32 gigaton reduction needed to limit temperature rise. The six sectors identified are agriculture and food; forests and land use; buildings and cities; transport; energy; and cities.
