Ireland looks to seaweed in quest to curb methane from cows

Source: Reuters

ATHENRY, Ireland, Nov 17 (Reuters) – Scientists are combing Ireland’s west coast for seaweed to feed to cattle and sheep after research showed it could stop them breathing out so much climate-warming methane.

The project, coordinated by a state agriculture body, is tapping into the country’s growing seaweed harvesting industry, which is seeking new markets as it revives centuries-old traditions.

But some are sceptical that the seaweed feed additives – or any quick technological fix – can sidestep the need to reverse a surge in Irish cattle numbers if the country is to reduce Europe’s largest per capita methane output by 2030.

Around 20 species of seaweed, most from Ireland’s windswept Atlantic coast, have been tested by researchers while dozens more have been collected by the project’s partners in Norway, Canada, Sweden, Germany and the United Kingdom.

Scientists in the United States and Australia have already demonstrated dramatic methane-reducing qualities from one seaweed type – Asparagopsis – when small quantities are added to feedstock.

But they have not yet managed to scale up production of the seaweed, which is not easy to grow in Northwest Europe.

The Irish project aims to find abundant native seaweeds to use instead, even though the researchers admit they are unlikely to match the reduction in emissions of over 80% shown with Asparagopsis.

“We have identified some brown seaweeds that are very positive and they’re producing results,” said Maria Hayes, Project Lead of the SeaSolutions project, whose team has achieved methane reductions of between 11% and 20% in early trials.

“The reductions aren’t going to be a silver bullet … but it can significantly reduce emissions,” said Hayes, who works for Teagasc, Ireland’s Agriculture and Food Development Authority.

Researchers are also working on how to integrate the feed additives into Ireland’s predominantly grass-based cattle farming system.

On a farm outside Hillsborough, southwest of Belfast, researchers use treats to coax cows to poke their heads into a solar-powered machine that measures the level of methane on their breath.

They will test them again using seaweed additives, said Sharon Huws, Professor of Animal Science and Microbiology at Queen’s University Belfast.

“The levels that are used to feed ruminants are very, very small so you don’t need to get a lot of it in order to get an impact,” she said.


The technology has caught the imagination of farming groups and politicians, who insist that stringent targets for cutting greenhouse gases like methane should not mean a reduction in the size of the Irish farming sector.

After growth of over 10% in the past 10 years, Ireland has 7.4 million cattle and is one of the largest exporters of beef and dairy in Europe.

Its per capita output of methane – which has a higher heat-trapping potential than CO2 – is by far the highest in the European Union, according to the Climate Watch database.

The colourless and odourless gas leaks from waste dumps, oil and gas infrastructure and the digestive systems of cattle and sheep.

At the COP26 U.N. Climate Change conference in Glasgow this month, Ireland signed up to a pledge to cut global output of methane by 30% by 2030 from 2020 levels.

But government ministers insist that will mostly be achieved through a 50% cut in non-agricultural methane, with a reduction of just 10% in agricultural methane by 2030.

They point to seaweed feed additives as a way to curb emissions without downsizing the herd – with a reduction in the average age of slaughter of beef cattle and genetics research as other possible solutions.

Chemicals company Royal DSM (DSMN.AS) says a rival food additive it produces can cut methane output by around 30%. The company said it had received regulatory approval in Brazil and Chile and is seeking approval in the European Union.

But not everyone is convinced the technology can meet the target.

“Scaling up these solutions takes time. We don’t have time,” said Sadhbh O’Neill, lecturer in climate policy and environmental politics at Dublin City University, a vocal critic of industry attempts to rely on technology rather than address the sustainability Ireland’s agriculture model.


The Irish researchers have tapped into a network of seaweed harvesters who are reviving a tradition mentioned in monastic writings as far back as the 5th century.

But they do not yet have a plan to scale up production if tests are successful.

Some harvesters, who serve organic food and cosmetic markets, doubt the feed additives will be sufficiently lucrative with plenty of opportunities elsewhere.

“It’s a huge market at the moment, seaweed is really thriving,” said Evan Talty, managing director at Wild Irish Seaweeds, who has revived harvesting techniques used by his grandfather and focuses on food and skin care products. The methane additive market is “not on our radar”, he said.

Others are more hopeful.

“Everyone keeps an eye on it,” said Jenny O’Halloran of Bláth na Mara, a small-scale hand harvester on Inis Mór island off Ireland’s west coast.

“Maybe the future of that is actually farming seaweed, which I think has to be part of the conversation when it comes to the future of seaweed in Ireland,” she said.

Green growth: The unstoppable rise of climate technology investment

Source: Finance Derivative

With the investment community focusing more and more on renewable technologies, investor interest is at an all-time high. Ian Thomas, managing director, Turquoise, reviews the current investment landscape and highlights the opportunities for investors keen to capitalise on this growing trend.

Green, or climate, finance is a label for providers of finance who are supporting investments seeking positive environmental impact. The label covers investments in green infrastructure, venture capital investment in clean technologies and renewable energy. Green finance has grown by leaps and bounds in recent years, supporting public wellbeing and social equity while reducing environmental risks and improving ecological integrity.

Worldwide, energy investment is forecast to increase by 8% in 2022 to $2.4 trillion, according to a new report by the International Energy Agency, with the expected rise coming mostly from clean energy – $1.4 trillion in total. To put this rocketing figure into some perspective, clean energy investment only rose by 2% annually in the five years following the signing of the Paris Agreement in 2015. Energy transition investment has some way to go, however – between 2022 and 2025, to get on track for global net zero, it must rise by three times the current amount to average $2,063 billion. [1]

Turquoise has been active for almost 20 years as a venture capital investor and adviser to companies in the climate technology space that are raising capital and/or selling their business to a strategic acquirer. Reviewing current industry investment news, as well as drawing on examples from the portfolio of Low Carbon Innovation Fund 2 (LCIF2), managed by Turquoise, I have commented below the latest on the renewable energy trends most piquing investor interest.

Solar PV

Renewable power is leading the charge when it comes to investment, with wind energy and solar PV emerging as the cheapest option for new power generation across many countries, and now accounting for more than 80% of total power sector investment. Solar power is responsible for half of new investment in renewable power, with spending divided roughly equally between utility scale projects and distributed solar PV systems.

This huge increase in solar spending, which continues in spite of supply chain issues affecting raw material delivery, has been driven by Asia, largely China (BloombergNEF, 2022). Meanwhile, Europe is re-doubling its efforts to achieve an energy transition away from Russian gas and other fossil fuels, building on investment that was already rising steadily prior to the outbreak of war in Ukraine. Germany, the UK, France and Spain all exceeded $10 billion on low-carbon spending in 2021.[2]


Last year was a record year for offshore wind deployment with more than 20GW commissioned, accounting for approximately $40 billion in investment. The first half of 2022 saw $32 billion invested in offshore wind, 52% more than in the same period in 2021 (BloombergNEF, 2022). Taking into account also onshore wind, in 2021 investment was spearheaded by China, followed by the US and Brazil.[3]

In the UK, suggested targets include plans to host 50GW of offshore wind capacity, as well as 10GW of green and blue hydrogen production, by 2030. Investors will naturally be encouraged by proposals to simplify the planning process across the board for renewable projects.[4] France and Germany have also increased their offshore wind targets, signalling further support for investment.

Decarbonising housing: the business opportunity

The need to decarbonise residential housing, made all the more urgent by current energy prices, also offers substantial scope for investment. The gas price spike is naturally increasing interest in technology such as electric heat pumps, which had already enjoyed 15% growth in 2021 albeit from a very low base.

Recently, Turquoise announced an investment by Low Carbon Innovation Fund 2 (LCIF2) in Switchd, which operates MakeMyHouseGreen, a data-driven platform that allows homeowners to source and install domestic renewable energy generation, including solar panels and battery storage with other energy saving products in the pipeline. The investment will enable Switchd to roll out the MakeMyHouseGreen platform to a much larger number of customers. The latest episode of the Talks with Turquoise podcast series saw us interview Switchd co-founder Llewellyn Kinch about the UK energy market and national transition to decarbonisation, covering the rise of residential renewable energy and energy efficiency.

Adapting to the low-carbon economy

Meanwhile, investors should not forget opportunities on the other side of the energy market. Renewables are undoubtedly exciting investors, but there are also opportunities for fossil fuel companies to adapt their business models to the low-carbon economy. Turquoise advised GT Energy, a portfolio company from our first fund that develops deep geothermal heat projects, on its sale to IGas Energy, a leading UK onshore oil & gas producer. Under IGas ownership, GT Energy will progress its flagship 14MW project to supply zero-carbon heat to the city of Stoke-on-Trent through a council-owned district heating network.

A broad investment landscape

Forecasts show that renewables will increase to 60% of power generation in Europe by 2030, and 40% in the US and China by the same date.[5] As demand rises for climate technology, the investment opportunities in green finance are far broader than they ever have been. Undoubtedly, as the energy crisis continues, investor interest will continue to soar to even greater heights.

The Businesses Making Mobility Change for Cleaner Air

By Tomas Edwards, Head of Marketing, Daloop 

Last month, the UK marked its 6th annual Clean Air Day, the UK’s largest campaign on air pollution. Since its founding in 2017, the campaign has been educating the public on the dangers of air pollution, which causes up to 36,000 UK deaths per year. Perhaps most importantly, though, Clean Air Day 2022 encouraged the UK public to consider the decisions that impact their own toxic emissions and make large or small, meaningful changes for the health of their communities.  

Of all the viable changes available to us, of which there are many, embracing more sustainable mobility alternatives is perhaps one of the most impactful. From daily commutes and summer getaways to e-commerce delivery and the transportation of goods, conventional transport carries huge consequences for our own, and others’, quality of life. 

Understanding your impact 

For those galvanised by Clean Air Day 2022, understanding the impact of your daily decisions is fundamental to reducing emissions.  

One of the resources on Global Action Plan’s website is the simple yet effective clean air calculator. Asking a series of questions about a user’s commute, residential property and online shopping habits, the calculator offers a weekly pollution percentage, when compared to the national average.   

Resources like this aren’t about placing blame, but rather, much like the calculator questions reveal, they highlight the ways in which the different choices we make can have substantial positive impacts on our planet and the health of our community.  

But of course, individuals making emission-reducing changes aren’t looking to do so alone. Those consumers who are taking steps to improve air quality in their own lives want to see the organisations and businesses that they buy from do the same.  

The businesses driving change 

Much like Global Action Plan’s clean air calculator aims to motivate individuals, ensuring businesses understand their impact is an essential first step in the move towards sustainable mobility. If you work with a fleet of corporate vehicles, why not try this fleet emissions calculator to understand the positive change you could deliver by investing in zero-emissions vehicles? 

Business fleets, whether delivery vans, HGVs, or employee vehicles, travel millions of miles a year and pump inordinate amounts of tailpipe emissions into the air around us. Road transport alone accounts for around a quarter of the UK’s carbon emissions, and electric vehicles, or EVs, are largely seen as an essential part of decarbonising transport.  

However, tailpipe emissions also have a big impact on the health of those closer to home, and Clean Air Day rightly calls on us to consider the other harmful pollutants generated by our day-to-day lifestyles. Nitrogen Oxides are produced when fuel is combusted in the presence of air, alongside other hydrocarbons, and tiny particles like brake dust can be fatal to those with existing lung and heart problems.  

For children living with air pollution, the toxic particles have been shown to stunt growth and brain development and cause long-term lung damage and asthma. A study in 2021 found that 27% of UK schools are in areas above the World Health Organisation’s air pollution limits, and this affects around 3.4 million schoolchildren. Therefore, the problem is on our doorstep. 

How can electric fleets help? 

Transitioning to electric vehicles (EVs) reduces many kinds of air pollution. Without tailpipe emissions, these vehicles not only contribute to decarbonisation efforts, but they also run without emitting NOx, a particularly aggressive pollutant that damages airways and internal organs. Combustion cars also generate brake dust, a toxic air pollutant that makes up 20% of traffic-related particles. By replacing the conventional disc braking design of combustion vehicles with regenerative electric braking, EVs eliminate brake dust alongside all other tailpipe emissions. 

By transitioning to electric fleets, businesses have the power to improve air quality for their own employees and the wider population, and to even encourage positive change across whole industries. Initiatives like the Clean Van Commitment draw attention to the importance of fleet electrification, challenging signatories to embrace zero tailpipe emission vans by 2028.  

Although air pollution may not be something everyone contributes to equally, it is something that everyone can play a role in reducing. As some of the largest contributors to road transport emissions, businesses and organisations alike should be aware of the power that their mobility choices have over the health and air quality of the areas they operate in.  

Days like Clean Air Day are an opportunity to reflect on these choices and to take pride in the changes, however large or small, we make every day. For organisations with large fleets, these changes can carry huge net-positives, ensuring the health and morale of workers and nearby residents, the faith of consumers, and contributing to the national movement to boost air quality.

How fintech is key to empowering climate action

Source: Finance Derivative

Attributed to: Rory Spurway, CEO & Founder of CarbonPay

As human activity continues to have a significant impact on the climate in unprecedented ways; particularly through disconcerting levels of CO2 emissions that contribute to global warming, there is an urgent need  for sustainability to be an integral part of the way industries operate. Research has found that 6 in 10 consumers think UK-based businesses need to do more to combat climate change and cut emissions. To meet the target of reducing 100% of emissions by 2050, innovation and accessibility are essential.  This global crisis paves the way for fintech, a major driving source of innovation, to create new ways of decarbonisation and climate action.

Because of this positionality, the  growing fintech sector has a significant role to play when it comes to mitigating the worst of climate change. For instance, new technologies such as data analytics, artificial intelligence, and creative innovations within the payments sector have disrupted how businesses can make a positive impact on the environment. One of the most significant ways that the fintech industry can make strides towards reducing emissions comes from partnerships with other businesses. The largest firms, such as Visa and MasterCard, are already known for their environmental sustainability efforts and work with fintech companies to develop the right sustainability aids, such as carbon reduction tools. Fintech can also be used as a catalyst to enforce positive climate action from a B2B standpoint, which is particularly key in a time where many of the biggest companies globally are currently failing to meet their sustainability targets.

How can sustainable fintech tackle greenwashing?

A way companies demonstrate commitment to sustainability and climate action is through green pledges and activities, such as tree planting initiatives. While these are  well-meaning, they can’t be the only avenue taken to combat climate change. Relying solely on one-dimensional initiatives runs the risk of losing environmental efficacy and sometimes are unfortunately used for companies to present a sustainable front without following through — more commonly known as greenwashing. The fintech sector has the power to help companies combat greenwashing concerns, through changing the behaviours and mindset of C-suite executives, prioritising decarbonisation and  by providing tools for tracking emissions. Backed by technology led solutions, the fintech sector actually has a lot of power and capabilities when it comes to changing the face of sustainable action.

Changing the mindset at the C-Suite

One of the major reasons sustainability is still not properly prioritised is that not enough CEOs think like CSOs. CEOs tend to focus more on business and financial operations rather than on CSR, leaving that to CSOs (if the organisation has one). But what does this mean for climate action and sustainability? By adopting a CSO mindset and thinking about climate issues in the same way that CSOs do, CEOs and other C-Suites can make sustainability a key priority for the company rather than separating the two operations. In the same way that everyone has a part to play in ensuring the  wellbeing of our environment, it’s the joint responsibility of the C-Suites to ensure the company is doing its part as well.

Tracking emissions – the first necessary step to decarbonisation

The concept of digital payments is not new, but its development has transformed the way people live, and pay for things daily. Our spending behaviours are largely reliant on technology and have also had a significant impact on the environment, and this is very much tied to carbon emissions. Because of this, it’s essential we adopt tools that enable people to mitigate the negative impacts that their spending habits are having on the environment . One way in which fintech is leading this is by providing the tools to track carbon emissions, and subsequently creating a simple way to offset these emissions. Companies are able to directly and transparently view the impact of their purchases, and with the help of specialised fintech companies, these emissions can be offset. Enabling businesses and their employees to take these easy and small steps to take responsibility for their carbon footprint ensures that sustainability remains accessible and constant , even at a B2B level.
