To tackle the climate crisis, global unity and collaboration are needed. This was in part the thinking behind the Paris Agreement. It set a clear, collective target negotiated at the 2015 United Nations Climate Change Conference and signed the following year: to keep the increase in global average temperatures to well below 2 degrees Celsius above pre-industrial levels.
In November 2021, COP26 will see many of the countries who first signed the Paris Agreement come together in Glasgow for the first ‘global stocktake’ of their environmental progress since its creation.

Already delayed for a year as a result of the pandemic, COVID-19 and its effects on emissions is likely to be a key talking point. So too will progress towards not just the Paris Agreement goals but those of individual countries. Known as ‘National Determined Contributions’ (NDCs), these sit under the umbrella of the Paris Agreement goals and set out individual targets for individual countries.
With many countries still reeling from the effects of COVID-19, the question is: which countries are actually on track to meet them?
The NDCs of each country represent its efforts and goals to reduce national emissions and adapt to the impacts of climate change. These incorporate various targets, from decarbonisation and forestry to coastal preservation and financial aims.
While all countries need to reduce emissions to meet the Paris Agreement targets, not all have an equally sized task. The principle of differentiated responsibility acknowledges that countries have varying levels of emissions, capabilities and economic conditions.
The Universal Ecological Fund outlined the emissions breakdown of the top four emitters, showing that combined, they account for 56% of global greenhouse gas emissions. China is the largest emitter, responsible for 26.8%, followed by the US which contributes 13.1%. The European Union and its 28 member states account for nine per cent, while India is responsible for seven per cent of all emissions.
These nations have ambitious emissions goals, but are they on track to meet them?
Traffic jams in the rush hour in Shanghai Downtown, contribute to high emissions in China.
By 2030, China pledged to reach peak carbon dioxide (CO2), increase its non-fossil fuel share of energy supply to 20% and reduce the carbon intensity – the ratio between emissions of CO2 to the output of the economy – by 60% to 65% below 2005 levels.
COVID-19 has increased the uncertainty of the course of China’s emissions. Some projections show that emissions are likely to grow in the short term, before peaking and levelling out sometime between 2021 and 2025. However, according to the Climate Action Tracker it is also possible that China’s emissions have already peaked – specifically in 2019. China is expected to meet its non-fossil energy supply and carbon intensity pledges.
The forecast for the second largest emitter, the US, has also been affected by the pandemic. Economic firm Rhodium Group has predicted that the US could see its emissions drop between 20% and 27% by 2025, meeting its target of reducing emissions by 26% to 28% below 2005 levels.
However, President Trump’s rolling back of Obama-era climate policies and regulations, his support of fossil fuels and withdrawal from the Paris Agreement (effective from as early as 4 November 2020), suggest any achievement may not be long-lasting.
The United States’ Coronavirus Aid, Relief, and Economic Security Act, known as the CARES Act, does not include any direct support to clean energy development – something that could also change in 2021.

The European Union and its member states, then including the UK, pledged to reduce emissions by at least 40% below 1990 levels by 2030 – a target the Climate Action Tracker estimates will be achieved. In fact, the EU is on track to cut emissions by 58% by 2030.
This progress is in part a result of a large package of measures adopted in 2018. These accelerated the emissions reductions, including national coal phase-out plans, increasing renewable energy and energy efficiency. The package also introduced legally binding annual emission limits for each member state within which they can set individual targets to meet the common goal.
The UK has not yet released an updated, independent NDC. However, it has announced a £350 million package designed to cut emissions in heavy industry and drive economic recovery from COVID-19. This includes £139 million earmarked to scale up hydrogen production, as well as carbon capture and storage (CCS) technology, such as bioenergy with carbon capture (BECCS) – essential technologies in achieving net zero emissions by 2050 and protecting industrial regions.
India, the fourth largest global emitter, is set to meet its pledge to reduce its emissions intensity by 33% to 35% below 2005 levels and increase the non-fossil share of power generation to 40% by 2030. What’s more, the Central Electricity Agency has reported that 64% of India’s power could come from non-fossil fuel sources by 2030.

Along with increasingly renewable generation, the implementation of India’s National Smart Grid Mission aims to modernise and improve the efficiency of the country’s energy system.
It is promising that the world’s four largest emitters have plans in place and are making progress towards their decarbonisation goals. However, tackling climate change requires action from around the entire globe. In addition to NDCs, many countries have committed to, or have submitted statements of intent, to achieve net zero carbon emissions in the coming years.

While the COVID-19 pandemic has disrupted short-term plans, many see it as an opportunity to rejuvenate economies with sustainability in mind. COP26, as well as the global climate summit planned for December of this year, will likely see many countries lay out decarbonisation goals that benefit both people’s lives and the planet.

Today our organisations have launched a new coalition with a shared vision: to build back better as part of a sustainable and resilient recovery from Covid-19, by developing pioneering projects that can remove carbon dioxide (CO2) and other pollutants from the atmosphere. Together, we represent hundreds of thousands of workers across some of the UK’s most critical industries, including aviation, energy and farming, each of which contribute billions of pounds each year to the economy.
A growing number of independent experts, including the Committee on Climate Change, Royal Society and Royal Academy of Engineering and the Electricity System Operator, have recognised the crucial role of ‘negative emissions’ or ‘greenhouse gas removal’ technologies in fighting the climate crisis. Whilst we should seek to decarbonise sectors such as aviation, heavy industry and agriculture as far as practically possible, due to technical or commercial barriers it is unlikely we will eliminate their greenhouse gas emissions completely. Negative emissions technologies are critical therefore to balancing out these residual emissions and ensuring we achieve Net Zero in a credible, cost effective and sustainable way.
As well as benefiting the environment, negative emissions technologies and projects can build back a cleaner, greener economy in the wake of Covid-19. The foundations for this are already being laid by our coalition’s members today.
For example:
With COP26 fast approaching, there is a real and compelling opportunity for the UK Government to demonstrate to the world it is taking a leadership position on negative emissions. Conversely if the UK does not act quickly, it could jeopardise the delivery of projects in the 2020s that can support innovation, learning by doing and the scale-up of negative emissions in the 2030s. It also risks Britain falling behind in the race to scale and commercialise these technologies, with a view to exporting them to other countries around the world to support their own decarbonisation efforts.
We would welcome the opportunity to meet with each of you to discuss these points in further detail.
Yours,

We’re familiar with using natural gas every day in heating homes, powering boilers and igniting stove tops. But this same natural gas – predominantly methane – is also one of the most important sources of electricity to the UK. In 2019 gas generation accounted for 39% of Great Britain’s electricity mix. But that could soon be changing.
Hydrogen, the super simple, super light element, can be a zero-carbon emissions source of fuel. While we’re used to seeing it in everyday in water (H2O), as a gas it has been tested as an alternative to methane in homes and as a fuel for vehicles.
Could it also replace natural gas in power stations and help keep the lights on?
Hydrogen fuel station
Natural gas has been the largest single source of electricity in Great Britain since around 2000 (aside from the period 2012-14 when coal made a resurgence due to high gas prices). The dominance of gas over coal is in part thanks to the abundant supply of it in the North Sea. Along with carbon pricing, domestic supply makes gas much cheaper than coal, and much cleaner, emitting as much as 60% less CO2 than the solid fossil fuel.
Added to this is the ability of gas power stations to start up, change their output and shut down very quickly to meet sudden shifts in electricity demand. This flexibility is helpful to support the growth of weather-dependant renewable sources of power such as wind or solar. The stability gas brings has helped the country decarbonise its power supply rapidly.
Hydrogen, on the other hand, can be an even cleaner fuel as it only releases water vapour and nitrous oxide when combusted in large gas turbines. This means it could offer a low- or zero-carbon, flexible alternative to natural gas that makes use of Great Britain’s existing gas infrastructure. But it’s not as simple as just switching fuels.
Some thermal power stations work by combusting a fuel, such as biomass or coal, in a boiler to generate intense heat that turns water into high-pressure steam which then spins a turbine. Gas turbines, however, are different.
Engineer works on a turbine at Drax Power Station
Instead of heating water into steam, a simple gas turbine blasts a mix of gas, plus air from the surrounding atmosphere, at high pressure into a combustion chamber, where a chemical reaction takes place – oxygen from the air continuously feeding a gas-powered flame. The high-pressure and hot gasses then spin a turbine. The reaction that takes place inside the combustion chamber is dependent on the chemical mix that enters it.
“Natural gas turbines have been tailored and optimised for their working conditions,” explains Richard Armstrong, Drax Lead Engineer.
“Hydrogen is a gas that burns in the same way as natural gas, but it burns at different temperatures, at different speeds and it requires different ratios of oxygen to get the most efficient combustion.”
Switching a power station from natural gas to hydrogen would take significant testing and refining to optimise every aspect of the process and ensure everything is safe. This would no doubt continue over years, subtly developing the engines over time to improve efficiency in a similar way to how natural gas combustion has evolved. But it’s certainly possible.
What may be trickier though is providing the supply of hydrogen necessary to power and balance the country’s electricity system.
Hydrogen is the most abundant element in the universe. But it’s very rare to find it on its own. Because it’s so atomically simple, it’s highly reactive and almost always found naturally bonded to other elements.
Water is the prime example: it’s made up of two hydrogen atoms and one oxygen atom, making it H2O. Hydrogen’s tendency to bond with everything means a pure stream of it, as would be needed in a power station, has to be produced rather than extracted from underground like natural gas.
Hydrogen as a gas at standard temperature and pressure is known by the symbol H2.
A power station would also need a lot more hydrogen than natural gas. By volume it would take three times as much hydrogen to produce the same amount of energy as would be needed with natural gas. However, because it is so light the hydrogen would still have a lower mass.
“A very large supply of hydrogen would be needed, which doesn’t exist in the UK at the moment,” says Rachel Grima, Research & Innovation Engineer at Drax. “So, at the same time as converting a power plant to hydrogen, you’d need to build a facility to produce it alongside it.”
One of the most established ways to produce hydrogen is through a process known as steam methane reforming. This applies high temperatures and pressure to natural gas to break down the methane (which makes up the majority of natural gas) into hydrogen and carbon dioxide (CO2).
The obvious problem with the process is it still emits CO2, meaning carbon capture and storage (CCS) systems are needed if it is to be carbon neutral.

“It’s almost like capturing the CO2 from natural gas before its combusted, rather than post-combustion,” explains Grima. “One of the advantages of this is that the CO2 is at a much higher concentration, which makes it much easier to capture than in flue gas when it is diluted with a lot of nitrogen.”
Using natural gas in the process produces what’s known as ‘grey hydrogen’, adding carbon capture to make the process carbon neutral is known as ‘blue hydrogen’ – but there are ways to make it with renewable energy sources too.
Electrolysis is already an established technology, where an electrical current is used to break water down into hydrogen and oxygen. This ‘green hydrogen’ cuts out the CO2 emissions that come from using natural gas. However, like charging an electric vehicle, the process is only carbon-neutral if the electricity powering it comes from zero carbon sources, such as nuclear, wind and solar.
It’s also possible to produce hydrogen from biomass. By putting biomass under high temperatures and adding a limited amount of oxygen (to prevent the biomass combusting) the biomass can be gasified, meaning it is turned into a mix of hydrogen and CO2. By using a sustainable biomass supply chain where forests absorb the equivalent of the CO2 emitted but where some fossil fuels are used within the supply chain, the process becomes low carbon.

CCS can then be added to make it carbon negative overall, meaning more CO2 is captured and stored at forest level and in below-ground carbon storage than is emitted throughout its lifecycle. This form of ‘green hydrogen’ is known as bioenergy with carbon capture and storage (BECCS) hydrogen or negative emissions hydrogen.
There are plenty of options for making hydrogen, but doing it at the scale needed for power generation and ensuring it’s an affordable fuel is the real challenge. Then there is the issue of transporting and working with hydrogen.
“The difficulty is less in converting the UK’s gas power stations and turbines themselves. That’s a hurdle but most turbine manufacturers already in the process of developing solutions for this,” says Armstrong.
“The challenge is establishing a stable and consistent supply of hydrogen and the transmission network to get it to site.”
Today hydrogen is mainly transported by truck as either a gas or cooled down to minus-253 degrees Celsius, at which point it becomes a liquid (LH2). However, there is plenty of infrastructure already in place around the UK that could make transporting hydrogen significantly more efficient.
“The UK has a very advanced and comprehensive gas grid. A conversion to hydrogen would be more economic if you could repurpose the existing gas infrastructure,” says Hannah Steedman, Innovation Engineer at Drax.
“The most feasible way to feed a power station is through pipelines and a lot of work is underway to determine if the current natural gas network could be used for hydrogen.”
Hydrogen is different to natural gas in that it is a very small and highly reactive molecule, therefore it needs to be treated differently. For example, parts of the existing gas network are made of steel, a metal which hydrogen reacts with, causing what’s known as hydrogen embrittlement, which can lead to cracks and failures that could potentially allow gas to escape. There are also factors around safety and efficiency to consider.
Like natural gas, hydrogen is also odourless, meaning it would need to have an odourant added to it. Experimentation is underway to find out if mercaptan, the odourant added to natural gas to give it a sulphuric smell, is also compatible with hydrogen.
But for all the challenges that might come with switching to hydrogen, there are huge advantages.
The UK’s gas network – both power generation and domestic – must move away from fossil fuels if it is to stop emitting CO2 into the atmosphere, and for the country to reach net zero by 2050. While the process will not be as simple as switching gases, it creates an opportunity to upgrade the UK’s gas infrastructure – for power, in homes and even as a vehicle fuel.

It won’t happen overnight, but hydrogen is a proven energy fuel source. While it may take time to ramp up production to a scale which can meet demand, at a reasonable cost, transitioning to hydrogen is a chance to future-proof the gas systems that contributes so heavily to the UK’s stable power system.
In order to meet the long-term climate goals laid out in the Paris Agreement, there is a need to not only reduce the emission of harmful greenhouse gases into the air, but actively work to remove the excess carbon dioxide (CO2) currently in the atmosphere, and the CO2 that will continue to be emitted as economies work to decarbonise.
The process of greenhouse gas removal (GGR) or CO2 removal (CDR) from the atmosphere is possible through negative emissions, where more CO2 is taken out than is being put into the atmosphere. Negative emissions can be achieved through a range of nature-based solutions or through man-made technologies designed to remove CO2 at scale.
One millennia-old way of achieving negative emissions is forests. Trees absorb carbon when they grow, either converting this to energy and releasing oxygen, or storing it over their lifetime. This makes forests important tools in limiting and potentially reducing the amount of CO2 in the atmosphere. Planting new forests and regenerating forests has a positive effect on the health of the world as a result.
However, this can also go beyond forests on land. Vegetation underwater has the ability to absorb and store CO2, and seagrasses can in fact store up to twice as much carbon as forests on land – an approach to negative emissions called ‘blue carbon’.
Bhutan is the only carbon negative country in the world – its thick forests absorb three times the amount of CO2 the small country emits.
Many scientists and experts agree one of the most promising technologies to achieve negative emissions is bioenergy with carbon capture and storage (BECCS). This approach uses biomass – sourced from sustainably managed forests – to generate electricity. As the forests used to create biomass absorb CO2 while growing, the CO2 released when it is used as fuel is already accounted for, making the whole process low carbon.
By then capturing and storing any CO2 emitted (often in safe underground deposits), the process of electricity generation becomes carbon negative, as more carbon has been removed from the atmosphere than has been added.
Direct air carbon capture and storage (DACCS) is an alternative technological solution in which CO2 is captured directly from the air and then transported to be stored or used. While this could hold huge potential, the technology is currently in its infancy, and requires substantial investment to make it a more widespread practice.
The process of removing CO2 from the atmosphere is known as negative emissions, because more CO2 is being taken out of the atmosphere than added into it.
According to the Intergovernmental Panel on Climate Change, negative emissions technologies could be required to capture 20 billion tonnes of carbon annually to help prevent catastrophic changes in the climate between now and 2050.
Carbon capture and storage (CCS) is the process of trapping or collecting carbon emissions from a large-scale source – for example, a power station or factory – and then permanently storing them.
Carbon capture usage and storage (CCUS) is where captured carbon dioxide (CO2) may be used, rather than stored, in other industrial processes or even in the manufacture of consumer products.
Carbon can be captured either pre-combustion, where it is removed from fuels that emit carbon before the fuel is used, or post-combustion, where carbon is captured directly from the gases emitted once a fuel is burned.
Pre-combustion carbon capture involves solid fossil fuels being converted into a mixture of hydrogen and carbon dioxide under heat pressure. The separated CO2 is captured and transported to be stored or used.
Post-combustion carbon capture uses the addition of other materials (such as solvents) to separate the carbon from flue gases produced as a result of the fuel being burned. The isolated carbon is then transported (normally via pipeline) to be stored permanently – usually deep underground – or used for other purposes.
Carbon capture and storage traps and removes carbon dioxide from large sources and most of that CO2 is not released into the atmosphere.
Once carbon is captured it can be stored permanently or used in a variety of different ways. For example, material including carbon nanofibres and bioplastics can be produced from captured carbon and used in products such as airplanes and bicycles, while several start-ups are developing methods of turning captured CO2 into animal feed.
Captured carbon can even assist in the large-scale production of hydrogen, which could be used as a carbon-neutral source of transport fuel or as an alternative to natural gas in power generation.
Carbon can be stored in geological reserves, commonly naturally occurring underground rock formations such as unused natural gas reservoirs, saline aquifers, or ‘unmineable’ coal beds. The process of storage is referred to as sequestration.
The underground storage process means that the carbon can integrate into the earth through mineral storage, where the gas chemically reacts with the minerals in the rock formations and forms new, solid minerals that ensure it is permanently and safely stored.
Carbon injected into a saline aquifer dissolves into the water and descends to the bottom of the aquifer in a process called dissolution storage.
According to the Global CCS Institute, over 25 million tonnes of carbon captured from the power and industrial sectors was successfully and permanently stored in 2019 across sites in the USA, Norway and Brazil.
CO2 is a greenhouse gas, which traps heat in our atmosphere, and therefore contributes to global warming. By capturing and storing carbon, it is being taken out of the atmosphere, which reduces greenhouse gas levels and helps mitigate the effects of climate change.
Decarbonisation is the term used for the process of removing or reducing the carbon dioxide (CO2) output of a country’s economy. This is usually done by decreasing the amount of CO2 emitted across the active industries within that economy.
Currently, a wide range of sectors – industrial, residential and transport – run largely on fossil fuels, which means that their energy comes from the combustion of fuels like coal, oil or gas.
The CO2 emitted from using these fuels acts as a greenhouse gas, trapping in heat and contributing to global warming. By using alternative sources of energy, industries can reduce the amount of CO2 emitted into the atmosphere and can help to slow the effects of climate change.
There are numerous greenhouse gases that contribute to global warming, however CO2 is the most prevalent. As of 2018, carbon levels are the highest they’ve been in 800,000 years.
The Paris Agreement was created to hold nations accountable in their efforts to decrease carbon emissions, with the central goal of ensuring that temperatures don’t rise 2 degrees Celsius above pre-industrial level.
With 195 current signatories, economies have begun to factor in the need for less investment in carbon, with the UK leading the G20 nations in decarbonising its economy in the 21st century.
There are numerous energy technologies that aim to reduce emissions from industries, as well as those that work towards reducing carbon emissions from the atmosphere.
Decarbonisation has had the most progress in electricity generation because of the growth of renewable sources of power, such as wind turbines, solar panels and coal-to-biomass upgrades, meaning that homes and businesses don’t have to rely on fossil fuels. Other innovations, such as using batteries and allowing homes to generate and share their own power, can also lead to higher rates of decarbonisation. As the electricity itself is made cleaner, it therefore assists electricity users themselves to become cleaner in the process.
Other approaches, such as reforestation or carbon capture and storage, help to pull existing carbon from the air, to neutralise carbon output, or in some cases, help to make electricity generation – and even entire nations – carbon negative.
Alternative power options means that homes and businesses don’t have to rely on traditional carbon fuels.
For decarbonisation to be more widely adopted as a method for combating climate change, there needs to be structural economical change, according to Deloitte Access Economics. Creating more room for decarbonisation through investing in alternative energies means that “there are a multitude of job-rich, shovel-ready, stimulus opportunities that also unlock long-term value”.

On the eve of the new F1 season, the motor sport faces an existential dilemma. While the Covid-19 pandemic has inflicted huge uncertainty throughout 2020, environmental concerns continue to question its long-term viability.
The Australian Grand Prix in Melbourne has long been the curtain-raiser to eight months of gas-guzzling, decibel-deafening action on racetracks across the globe, contributing to a carbon footprint of 256,551 tonnes. Due to the season being delayed, the first race will now take place in Austria. But the focus on Australia has been sharpened by the New Year bushfires – visible evidence, say some scientists and environmentalists, of the climate crisis. This adds fuel to the fiery debate on Formula One’s perceived failure to take its environmental responsibilities seriously.
Koala bear on eucalyptus branch escaping from Australian bushfires in 2019 and 2020.
Significantly, it is not the cars doing 70 laps that generate most of F1’s emissions but the thousands of air miles covered by drivers, their teams, the media and spectators in getting to each race weekend:
Activity | % of carbon footprint |
---|---|
🚚 Logistics (road, air and sea freight) | 45% |
🛩 Personnel travel | 27.7% |
🏭 Factories and facilities | 19.3% |
🎤 Events | 7.3% |
🏎 Total F1 car emissions including all race and test mileage | 0.7% |
But is a genuine shift in attitudes about to descend on the circuits of Monaco, Silverstone and Interlagos? Firstly, a raft of countries have announced plans to phase out petrol and diesel-powered engines between 2030 and 2050. This could force the hand of motorsport bosses who have long been accused of talking a good game but failing to act.
The sport recently announced a pledge to become carbon neutral by 2030 and in pursuit of this goal, it is looking to introduce two-stroke engines that run on synthetic fuel by the mid-2020s while current F1 hybrid engines will be replaced by a new specification of power unit from 2025 or 2026.
Max Verstappen, Formula One driver
Currently, under Article 19.4.4 of the FIA’s 2019 technical regulation for F1 a minimum of 5.75% of the fuel must comprise bio‐components. The sport wants to reach 100%, aiming for 10% in 2021 and a gradual subsequent increase.
Such developments could potentially seize upon the opportunities offered by companies pioneering the use of carbon capture, use and storage (CCUS), such as Drax.
One of several ideas discussed to make the sport more sustainable has been capturing carbon that is then mixed with hydrogen from water to form liquid fuel. Such technology is in development and Drax is researching how carbon dioxide (CO2) can be used to produce fuels. Its innovation engineers recently met with Velocys, the fuels technology company, which plans to produce carbon negative fuels in the Humber.
While greener fuels are the most obvious way forward, there have been calls for alternative forms of energy to be used to power F1 cars. A hydrogen solution could be developed quickly but it would significantly increase the bulkiness and weight of cars. But what about electric?
Formula One race car
“Electric power is attractive, but it’s currently still quite difficult to scale that up,” Pat Symonds, Chief Technical Officer at Formula One, said in an interview. “With any of the technologies on the horizon at the moment an electric truck or an electric aircraft is not a particularly feasible product. So, there is still a case for having liquid hydrocarbon fuels in trucks and in aircraft. However, what we cannot do is carry on digging those out of the ground, we’re going to have to somehow synthesise them and that’s what we want Formula 1 to explore and hopefully to lead.”
Another driver of change looming larger in Formula One’s rear-view mirror is Formula E. While this fledgling sport’s claim to quieter cars may not appeal to the most hardened of petrol-head F1 fans, its credible narrative of boosting sustainability in each of the 12 cities that host its races is always a potential attraction to new generations of increasingly climate conscious young fans.
Take Formula E’s opening race in Riyadh, Saudi Arabia, the country’s most polluted city. The sport is a beneficiary of the kingdom’s aim to reduce its reliance oil and in the last six years, the Middle Eastern country has invested over $350 billion in renewable energy projects (mainly solar and wind).

As with all electric cars, there are challenges. Excess heat produced by electric motors is offset by reducing the performance of the car when it is too hot. A series of cooling systems using radiators and fluid in closed loops regulate temperatures to a satisfactory level.
Appealing to fans is critical for the sport’s prosperity. Sustainability credentials are a key strand but Formula E is going beyond that and looking to optimise raceday experience through features such as FanBoost. This is an online voting system where the three drivers voted as fans’ favourites get a five second power boost of 100kj which can provide serious assistance when a car overtakes.
Maybe this is just one innovation that F1 could learn from its much younger counterpart? Perhaps there is also a case for taking the best of what both have to offer – the cities, the cars and the technology – and merging into a single championship. Whatever lies ahead in the future, Formula One is aware of the need to change. It must do if it is to survive.
