The temporary reduction in carbon emissions caused by global COVID-19 lockdowns did not slow the relentless advance of climate change. Greenhouse gas concentrations are at record levels, and the planet is on path towards dangerous overheating, a multi-agency climate report published on Thursday warns.
According to the landmark United in Science 2021, there “is no sign of growing back greener”, as carbon dioxide emissions are rapidly accelerating, after a temporary blip in 2020 due to COVID, and nowhere close to the targets set by the Paris Agreement.
“We have reached a tipping point on the need for climate action. The disruption to our climate and our planet is already worse than we thought, and it is moving faster than predicted”, UN Secretary General António Guterres underscored in a video message. “This report shows just how far off course we are”, he added.
A world in danger
According to scientists, the rising global temperatures are already fueling devastating extreme weather events around the world, with escalating impacts on economies and societies. For example, billions of working hours have been lost due to excessive heat.
“We now have five times the number of recorded weather disasters than we had in 1970 and they are seven times more costly. Even the most developed countries have become vulnerable”, said the UN chief.
Mr. Guterres cited how Hurricane Ida recently cut power to over a million people in New Orleans, and New York City was paralysed by record-breaking rain that killed at least 50 people in the region.
“These events would have been impossible without human-caused climate change. Costly fires, floods and extreme weather events are increasing everywhere. These changes are just the beginning of worse to come”, he warned.
A bleak future
The report echoes some of the data and warnings from experts in the last year: the average global temperature for the past five years was among the highest on record, and there is an increasing likelihood that temperatures will temporarily breach the threshold of 1.5° Celsius above the pre-industrial era, in the next five years.
The picture painted by United in Science is bleak: even with ambitious action to slow greenhouse gas emissions, sea levels will continue to rise and threaten low-lying islands and coastal populations throughout the world.
“We really are out of time. We must act now to prevent further irreversible damage. COP26 this November must mark that turning point. By then we need all countries to commit to achieve net zero emissions by the middle of this century and to present clear, credible long-term strategies to get there”, urged the UN chief.
The 2021 United Nations Climate Change Conference, also known as COP26, is scheduled to be held in the city of Glasgow, Scotland between 31 October and 12 November 2021. The pivotal meeting is expected to set the course of climate action for the next decade.
“We must urgently secure a breakthrough on adaptation and resilience, so that vulnerable communities can manage these growing (climate) risks…I expect all these issues to be addressed and resolved at COP26. Our future is at stake”, Mr. Guterres emphasized.
“We are not yet on track towards the Paris 1.5 to 2 degrees’ limit, although positive things have started to happen and the political interest to mitigate climate change is clearly growing but to be successful in this effort, we have to start acting now. We cannot wait for decades to act, we have to start acting already in this decade”, added Prof. Petteri Taalas, World Meteorological Organization’s secretary general.
The report also cites the conclusions of the most recent IPCC report: the scale of recent changes across the climate system are unprecedented over many centuries to many thousands of years, and it is unequivocal that human influence has warmed the atmosphere, ocean and land.
Concentrations of the major greenhouse gases – carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2 O) continued to increase in 2020 and the first half of 2021.
According to WMO, reducing atmospheric methane (CH4) in the short term, could support the pledges of 193 Member States made in Paris. This measure does not reduce the need for strong, rapid and sustained reductions in CO2 and other greenhouse gases.
Meanwhile, the UN Environment Program (UNEP), warns that five years after the adoption of the Paris Agreement, the emissions gap (the difference between where emissions are heading and where science indicate they should be in 2030) is as large as ever.
Although the increasing number of countries committing to net-zero emission goals is encouraging, to remain feasible and credible, these goals urgently need to be reflected in near-term policy and in significantly more ambitious actions, the agency highlights.
“Last year, we estimated that there was 5.6 per cent drop in emissions and since the lifetime of carbon dioxide is so long, this one year anomaly in emissions doesn’t change the big picture. We saw some improvements in air quality, these short-lived gases, which are affecting air quality. We saw positive evolution there. But now we have returned more or less back to the 2019 emission levels”, further explained the WMO chief.
A warmer future
The report explains that the annual global average temperature is likely to be at least 1 °C warmer than pre-industrial levels (defined as the 1850–1900 average) in each of the coming five years and is very likely to be within the range of 0.9 °C to 1.8 °C.
There is also a 40% chance that the average temperature in one of the next five years, will be at least 1.5 °C warmer than pre-industrial levels. However, it is very unlikely that the 5-year average temperature for 2021–2025 will pass the 1.5 °C threshold.
High latitude regions, and the Sahel, are likely to be wetter in the next five years, the report also warns.
Sea level rise is inevitable
“We don’t know what’s going to happen to the Antarctic glacier, where we have the biggest mass of ice worldwide and in the worst case, we could see up to two meters of sea level rise by the end of this century if the melting of the Antarctic glacier happens in a speedier manner”, cautioned Prof. Taalas.
Global sea levels rose 20 cm from 1900 to 2018, and at an accelerated rate from 2006 to 2018.
Even if emissions are reduced to limit warming to well below 2 °C, the global average sea level would likely rise by 0.3–0.6 m by 2100 and could rise 0.3–3.1 m by 2300.
Adaptation to the rise will be essential, especially along low-lying coasts, small islands, deltas and coastal cities, explains WMO.
World’s health also at risk
The World Health Organization (WHO) warns that rising temperatures are linked to increased heat-related mortality and work impairment, with an excess of 103 billion potential work hours lost globally in 2019 compared with those lost in 2000.
Moreover, COVID-19 infections and climate hazards such as heatwaves, wildfires and poor air quality, combine to threaten human health worldwide, putting vulnerable populations at particular risk.
According to the UN health agency, the COVID-19 recovery efforts should be aligned with national climate change and air quality strategies to reduce risks from cascading climate hazards, and gain health co-benefits.
“We had this temperature anomaly in western Canada and the United States, where we were up to 15 degrees warmer temperatures than normally. And that led to a record breaking, forest fires and major health problems, especially amongst elderly people”, highlighted WMO Secretary General.
Ghana Begins Receiving Payments for Reducing Carbon Emissions in Forest Landscapes
Ghana has become the second country in Africa after Mozambique to receive payments from a World Bank trust fund for reducing emissions from deforestation and forest degradation, commonly known as REDD+. The World Bank’s Forest Carbon Partnership Facility (FCPF) paid Ghana $4,862,280 for reducing 972,456 tons of carbon emissions for the first monitoring period under the program (June to December 2019).
“This payment is the first of four under the country’s Emission Reductions Payment Agreement (ERPA) with the World Bank to demonstrate potential for leveraging results based payments for carbon credits,” said Pierre Laporte, World Bank Country Director for Ghana, Liberia, and Sierra Leone. “Subject to showing results from actions taken to reduce deforestation, Ghana is eligible to receive up to $50 million for 10 million tons of CO2 emissions reduced by the end of 2024.”
These actions are within a six-million-hectare stretch of the West Africa Guinean Forest, where biodiversity and forests are under pressure from cocoa farming and unsustainable harvesting, and small-scale mining. Ghana is one of 15 countries that have signed ERPAs with the World Bank.
“The many years of dialogue, consultations, and negotiations with local communities, traditional authorities, government agencies, private sector, CSOs, and NGOs have paid off,” said Samuel A. Jinapor, Minister for Lands and Natural Resources. “This emission reductions payment will further promote confidence in Ghana’s REDD+ process for action to reduce deforestation and forest degradation while empowering local community livelihoods. The road to global 1.5 degrees cannot be achieved without healthy standing forests, and Ghana is committed to making it possible.”
Ghana is the world’s second-largest cocoa producer. Cocoa drives the economy, but it is also one of the main causes of deforestation and forest degradation in the southeast and western regions of the country. Stakeholders are working to help some 140,000 Ghanaian farmers increase cocoa production using climate-smart agro-forestry approaches, rather than slash and burn land-clearing techniques that decimate forests. More sustainable cocoa farming helps avoid expansion of cocoa farms into forest lands and secures more predictable income streams for communities.
Ghana’s Cocoa Board is participating in the REDD+ process, as are some of the most important cocoa and chocolate companies in the world, including World Cocoa Foundation members like Mondelēz International, Olam, Touton, and others. Their combined actions are not only helping bring change to the cocoa sector, but they are also helping Ghana meet its national emissions reductions commitments under the Paris Agreement. This level of collaboration is also reflected in the benefit sharing plan underpinning Ghana’s’ ERPA with the World Bank. Prepared through extensive consultations with local stakeholders and civil society organizations throughout the country, the plan ensures all participating stakeholders are fairly recognized and rewarded for their role in reducing emissions.
Soil and freshwater come under the spotlight in plastics-pollution fight
BY GARETH WILLMER
On a recent stroll to his local supermarket in the southern German town of Bayreuth, Christian Laforsch decided to count how much plastic trash he passed.
‘It was 52 pieces on only a normal walk,’ said Professor Laforsch, an ecologist at the University of Bayreuth. ‘The problem starts indoors before moving outside. If you open your door and look out onto the street, you will see plastics.’
Over time, plastic waste is weathered and breaks down into minute fragments – with those measuring less than 5 millimetres in diameter defined as microplastics. Much about their threat to the environment and human health remains unknown.
The lack of knowledge is particularly pronounced when it comes to soils and freshwater, with research to date tending to focus on microplastics in oceans. Yet terrestrial microplastics pollution may be four to 23 times higher than it is in seas.
‘We started as researchers in the marine system, then we went on to the freshwater system and terrestrial ecosystems,’ said Laforsch.
Interest in microplastics pollution in soils has grown over the past few years.
For example, a quick search on Science Direct for papers in 2018 on the subject brings up just over 150 results compared with around 450 for oceans. But for 2022, the figures are 2 300 to 2 400 for both soils and oceans.
‘People who work in environmental sciences found that microplastics are everywhere,’ said Dr Nasrollah Sepehrnia, a soil physicist at the University of Aberdeen in the UK.
However, investigating their effects in ecosystems such as soils is challenging.
‘Monitoring and tracing such materials is complex, and their fate in soil is not clear,’ said Sepehrnia. ‘But very likely they find a way to go into our food chain – and may impact our climate and the environment.’
Progress on the research front could help pinpoint ways to reduce microplastics and any effect they have on human health. With the EU recently proposing to limit the use of microplastics in industry and the United Nations calling last month for countries to work towards eliminating plastics pollution, research could also help determine the most important areas for further regulatory action.
The EU-funded TRAMPAS project that Sepehrnia works on is investigating microplastics pollution in soils. The focus is on the biological, chemical and physical impacts, including the potential effects on pathogens.
The surface or pores of microplastics can create artificial habitats for disease-causing organisms and protect them against harsh external environments, according to Sepehrnia.
‘Microplastics in soil could be a good harbour or shelter for other contaminants, potentially increasing the life of pathogens,’ he said.
The project will use a new approach to monitor the movement of bacteria, harnessing synthesised DNA to track how organisms are transported through the soil on microplastics and where they end up.
Studying microplastic particles measuring 1.5, 3 and 5 mm, Sepehrnia’s team noticed that the smaller the particle, the longer the contaminants such as bacteria appear to stay in soil.
‘When we have such information, it helps trace the contaminants’ fate,’ he said. ‘We can then use it to define management practices and regulations.’
Microplastics in soil may even play a role in global warming.
Plastics release greenhouse gases as they break down in soil. In addition, bacteria that hitch a lift on microplastics might contribute to increasing the amount of carbon dioxide released.
On top of this, work by TRAMPAS indicates that changes in the surface of degraded microplastics can make soils hydrophobic and, as a result, harder for water to permeate.
After microplastics move through the soil or arrive from other sources such as sewage treatment plants and runoff from streets, they often end up in streams and rivers before flowing into the sea.
The EU-funded LimnoPlast project led by Laforsch is focusing on microplastics in freshwater bodies. The team is investigating the sources, impact, removal options and possible policy responses of this invisible invader.
So far, LimnoPlast has discovered that some biodegradable plastics are potentially as harmful as traditional plastics. As a result, analysing the whole mix of constituents in finished plastic products is important, according to Laforsch.
A challenge is that microplastics are a diverse set of contaminants of varying polymer types, sizes and shapes rather than a single material – so it’s important to investigate these differences. Knowing more about them will help to inform manufacturing practices and EU regulation of the most harmful microplastics.
‘It might be that only some of those properties are responsible for the effects we see,’ said Laforsch. ‘If we know which properties do most harm, we can be more focused on these when it comes to the design of new polymers.’
LimnoPlast is testing a removal method that uses an electric field to isolate microplastic particles in wastewater.
The researchers are also developing new biodegradable polymers made from orange peels.
‘It’s hard to say when we will be successful in having a new material, but at the moment things look promising,’ Laforsch said.
Beyond hoping to lay the ground for an improved European legal framework for microplastics, LimnoPlast is training a new generation of interdisciplinary scientists in the field who have an understanding of the wider societal context of microplastics.
The project brings together experts with backgrounds in environmental, technical and social sciences from 14 research institutions and organisations across Europe – including Denmark, France, Germany, Slovenia and the UK.
‘You cannot tackle an environmental issue only by looking the natural-science part,’ said Laforsch. ‘You have to include social sciences and all the legal aspects.’
Expanding on that idea, he highlighted a need to think in a joined-up way across ecosystems too.
‘We should stop talking about it being a problem of the marine or the freshwater or the terrestrial system because it’s all interconnected,’ Laforsch said.

Decarbonization of Industrial Clusters Initiative Gains Global Momentum
Nine leading industrial clusters in China, Indonesia, Japan, Spain, and the United States have joined the World Economic Forum initiative, Transitioning Industrial Clusters towards Net Zero, to help industries reduce emissions.
Launched in 2021 and supported by Accenture and EPRI, the initiative focuses on reducing heavy industry asset emissions in regional industrial zones, while supporting job creation and increasing economic competitiveness.
Industrial clusters account for 15%-20% of global CO2 emissions, making them an attractive target for emission reductions. Industries in the same general location benefit not only from sharing risk, infrastructure and natural resources but also from a united approach to tackle decarbonization along with workforce transformation and environmental justice.
Industrial clusters are areas where companies, representing either a single or multiple industries, provide opportunities for scale, sharing of risk/resources, aggregation and optimization of demand.
The latest members of the initiative:
· Andalusian Green Hydrogen Valley, with projects in Palos de la Frontera (Huelva) and San Roque (Cádiz), Spain, aims to implement the largest green hydrogen project in Andalusia that offers a solid electricity grid, abundant low-cost renewable production, high industrial consumption and good connections by road, rail, air and maritime transport
· Canary Islands Industrial Cluster, Spain, aims to become a hub for sustainable aviation and clean shipping by using the islands’ significant solar and wind energy generation
· Greater St Louis and Illinois Regional Clean Hydrogen Hub Industrial Cluster, USA, a diverse group of industry, business and community groups and academic institutions collaborating to decarbonize the regional industrial sector and foster production and end-uses of hydrogen
· Indo-Pacific Net-zero Battery-Materials Consortium (INBC) in Indonesia, a cooperation to secure low-carbon battery materials from Indonesia to gigafactories in the UK and to launch the leading net-zero industrial park in Sulawesi
· Jababeka Net-Zero Industrial Cluster in Cikarang, Indonesia, includes various industries and the first publicly listed industrial cluster will focus on rooftop solar panels, biomass co-firing as a renewable substitute, organic waste management, circular manufacturing, electric mobility and hydrogen solutions
· Kawasaki Carbon Neutral Industrial Complex, Japan, with petroleum and chemicals at its core, as well as, steel and electric power industries, is pursuing hydrogen deployment, carbon recycling and the use of regional energy optimization
· National Capital Hydrogen Center, USA, helps to accelerate the clean energy transition of the Washington D.C., Maryland and Virginia region while supporting the regional and national imperative to deliver hydrogen solutions for US clean energy future
· Ordos-Envision Net Zero Industrial Park, China, integrates supply chains in Inner Mongolia for battery manufacturing and energy storage, electric vehicle, photovoltaic and green hydrogen equipment, features a high rate (>80%) of renewable penetration, a net-zero digital certification system and supports carbon neutrality for industries within the region
· Sanjiang New Area Industrial Park, China, aspires to achieve carbon neutrality across the local battery value chain by means of green electricity, intelligent energy management, sewage treatment and green transport, while leveraging the innovative experiences in zero-carbon factory and lighthouse factory of CATL’s Sichuan plant
The new members join eight other initiative signatory clusters: Brightlands Circular Space, H2Houston Hub, Ohio Clean Hydrogen Hub Alliance, Port of Antwerp-Bruges, Zero Carbon Humber, Hynet North West, Kwinana Industries Council, and the Basque Net-Zero Industrial Supercluster.
Combined, the new clusters add significant decarbonization potential, bringing the CO2 emissions of all the initiative’s members to 451 million metric tonnes emitted per year, comparable to the annual emissions of Turkey. The 17 members also contribute economically by employing more than 2.7 million people and represent an annual GDP contribution of $218 billion.
“Kawasaki, which is located between Tokyo and Yokohama, is one of the largest industrial cities in Japan where we are working with companies to form a base for importing CO2-free hydrogen from overseas and create an area that will drive carbon neutrality in Japan,” said Norihiko Fukuda, Mayor of Kawasaki City. “I’m confident these efforts will be strongly accelerated by deepening collaboration with other clusters through the initiative.”
Industrial clusters are powerful drivers of innovation at scale and knowledge sharing. The expanded initiative community includes new greenfield operations, particularly a number of hydrogen clusters that are future-energy export hubs aimed at developing international green energy corridors.
“Green hydrogen is the best low-carbon alternative for hard-to-abate sectors including industry and heavy transport,” said Maarten Wetselaar, CEO of Cepsa. “We see more and more customers keen to commit to green hydrogen consumption and southern Spain offers one of the best price points in Europe to produce it. Cepsa’s two projects in our Andalusian Green Hydrogen Valley, the largest green hydrogen hub in Europe, will help create a commercial construct to meet this demand, decarbonize local industry and begin to provide the scale Spain needs to become a net exporter of clean energy.”
“Indo-Pacific Net-zero Battery-materials Consortium (INBC) will accelerate developments of battery gigafactories across the world. As we play our part in the end-to-end global EV supply chain – started with Indonesia and the UK – we will position INBC as the go-to alternative for ESG-processed nickel and battery materials. Collaboration is the key to a successful net-zero sustainability transition and hence we are very excited to be joining the Transitioning Industrial Clusters towards Net-zero initiative,” said Anindya Bakrie, Consortium Lead Representative of INBC and CEO of Bakrie & Brothers.
Building on these developments, the initiative has published its first report, Transitioning Industrial Clusters towards Net Zero, and will host a number of public-private roundtables and regional workshops in 2023. These events will strengthen public-private collaboration and pursue further policy analysis beyond the recently published white paper, Transitioning Industrial Clusters towards Net Zero: National Policy Enablement for Industrial Decarbonization.
“The nine new industrial cluster members add momentum to our programme and diversify the locations and types of industries seeking to accelerate their decarbonization, making our initiative truly global and comprehensive,” said Roberto Bocca, Head of the Platform for Energy, Materials and Infrastructure, World Economic Forum. “The programme now covers several heavy industries sectors in nine countries across four continents. We encourage other industrial estates and hubs to join us in helping reduce CO2 emissions faster by creating international public-private and cross-industry partnerships which enable implementation of low-carbon technologies.”
