Agrifood

Greenhouse gas emissions statistics can be misleading. At a recent SCI webinar on the Future of Agriculture, the Agrisciences Committee put its finger on some glaring gaps in the figures.

If all of the cows in the world came together to form a country, that nation state would be the second highest emitter of greenhouse gas emissions in the world.

McKinsey Sustainability’s statistic was certainly startling. However, Agrisciences Group Chair Jeraime Griffith mentioned other equally striking figures in his wrapup of the social media discussion generated at COP26.
In his talk as part of the Agrisciences Committee’s COP26 – What does it mean for the future of agriculture? webinar on 7 December, Griffith also noted that:

  1. farming accounts for more than 70% of the freshwater used worldwide, according to the Organisation for Economic Co-operation and Development (OECD)
  2. and 31% of human-caused greenhouse gas emissions come from agrifood systems, according to the Food and Agriculture Organisation.

On the face of it, these figures are sobering; yet, like many agriculture-related figures, they don’t tell the full story.

Insane in the methane

Kathryn Knight felt that agriculture received negative press at COP26 in relation to greenhouse gas emissions. ‘It doesn't seem to take into account carbon sequestration (capturing and storing atmospheric carbon dioxide),’ said the Research & Technology Manager of Crop Care at Croda. ‘Why isn’t that being brought into the equation when we’re talking about carbon and agriculture?’
Martin Collison expanded on this point. He emphasised the need to separate carbon emissions by system – such as extensively grazed livestock animals and those fed on grain – and to account for systems that sequester carbon in the soil. The co-founder of agricultural consultancy Collison & Associates also pointed out the problem with bundling all our greenhouse gases as one.

Two cows in field, one laying down

Greenhouse gas emissions are sometimes unhelpfully bundled together, instead of being separated by gas and agricultural system.

‘We count methane in the same way we emit carbon,’ he said. ‘When we emit carbon, it’s in the atmosphere for 1,000 years, but with methane it’s 12 years. The methane cycle is a lot, lot shorter.’

And the difficulties with the statistics don’t end there. For example, countries often announce impressive emission reductions without taking trade into account. This, of course, gives the figures a greener gloss.

‘To me, there's a need to be more up front with a lot of the data because agriculture and food are traded around the world,’ he added. ‘A lot of the emissions data ignore what we trade.

‘In the UK, we make big claims about how fast we’ve progressed with carbon emissions, but if you look at what we consume, the progress is much much slower. The things we produce less of, we import.’

Full of hot air?

Emissions trading also serves to blur the picture. For Jeraime Griffith it is an unsatisfactory solution. ‘In terms of carbon trading, we have cases where the higher emitters continue producing in the way they’ve always been producing,’ he said.

‘It doesn't bring in any restrictions on the amount of carbon they emit; it just shifts the problem somewhere else. I don't know how carbon trading benefits us getting to Net Zero. It just seems to be kicking the ball farther down the road.’

Is emissions trading part of the solution or part of the problem?

So, when you take into account 1. emissions trading, 2. the absence of food imports in data sets, 3. the bundling together of different greenhouse gases in emissions figures, and 4. the failure to take carbon sequestration into account, it’s clear that many of the statistics we receive are incomplete.

‘There’s lots of complexity behind the numbers and we tend to lump all of it together,’ Collison said. ‘There’s a need to go much much further.’

At COP26, Nikita Patel co-hosted the Next-Gen debate, where an inspiring group of young people discussed how chemistry is tackling climate change. The PhD student at Queen Mary University of London shares her experience.

While the United Nations Climate Change Conference (COP26) may be over, there is still plenty to be done in the fight against climate change. We’ve seen what can be achieved when we work together and no doubt science will play a key role.

On Thursday 4 November, I had the privilege of co-hosting the Countdown to Planet Zero Next-Gen debate organised by SCI to showcase the work being carried out by our young and innovative scientists to tackle climate change. It was a real pleasure to share the stage and hear from some great scientists, exploring the themes Fuels of the Future, Turning Waste into Gold and Engineering Nature. The event gave the audience the opportunity to question and challenge the panel members on their climate change solutions.

Panel L-R: Dominic Smith, Natasha Boulding, Clare Rodseth, Jake Coole, Nikita Patel, Oliver Ring (Brett Parkinson joined virtually).

While I was feeling nervous about my hosting duties, I was very excited at the same time as I knew how important it was to educate the audience, whether they were members of the public or aspiring scientists, on how science is crucial in battling the climate emergency.

An important part of my role as a host was to ensure the incoming questions and comments were understood by all, given the mixed audience attending. This highlighted how essential good science communication is to prevent misunderstandings and the spread of misinformation.

It was brilliant to see how engaged the audience were from the flurry of questions that came in during the session, so much so that we didn’t manage to get through all of them! There were a wide variety of questions aimed at particular panellists but also towards the panel as a whole. It was thought-provoking to hear how scientists from different backgrounds offered their own perspectives on the same topic.

4 November was also Energy Day at COP26 and the atmosphere was buzzing! I learnt a lot from attending the Green Zone, not only from our panellists but from all the exhibitors present too. I appreciate the small, individual actions we can each take that will make a difference but also the need to work together to achieve the common goal of fighting climate change. It was clear to see how science and business go hand in hand to provide solutions to society and how interdisciplinary collaboration is key.

The result of our poll question: ‘Do you think that science is pivotal in providing climate change solutions?’ spoke for itself, with a resounding yes from 100% of the audience participants! This was a very positive outcome and showed that it is not all doom and gloom when it comes to discussing the climate crisis.

On a personal level, I'm going to continue implementing some simple changes like using public transport more, eating more vegan food and flying less and aim to keep the discussion going with my peers as the climate emergency is far from over.

‘This is a fragile win. We have kept 1.5 alive. That was our overarching objective when we set off on this journey two years ago, taking the role of the COP presidency-designate. But I would say the pulse of 1.5 is weak’ – Alok Sharma, President for COP26.

If scientists, politicians and activists were hoping that COP26, delayed by one year because of the pandemic, would yield concrete plans for progress on climate change, perhaps the overall conclusion might be ‘at least we haven’t gone backwards’.

The Glasgow Climate Pact, signed by 197 countries, required an extra day of negotiations. In his summing up, the UN Secretary General António Guterres said: ‘The approved texts are a compromise. They reflect the interests, the contradictions, and the state of political will in the world today.’

In his video statement Guterres said that the agreement ‘takes important steps but unfortunately the collective political will was not enough to overcome some deep contradictions. We must accelerate action to keep the 1.5 (degrees °C) goal alive…it’s time to go into emergency mode or our chance of reaching net-zero will indeed be zero.’

Guterres added that it was his conviction that it was time to phase out coal, end fossil fuel subsidies and build resilience in vulnerable communities. He also addressed the many young people and indigenous communities, saying: ‘I know you are disappointed. But the path to progress is not always a straight line…but I know we will get there. We are in the fight of our lives, and this fight must be won.’

The Glasgow Climate Pact calls on signatories to report their progress towards more climate ambition in time for COP27, which will be hosted by Egypt. Welcoming the agreement, Alok Sharma, COP26 President, said: ‘This is a fragile win. We have kept 1.5 alive. That was our overarching objective when we set off on this journey two years ago, taking the role of the COP presidency-designate. But I would say the pulse of 1.5 is weak.’

European Commission President Ursula von der Leyen said: ‘We have made progress on three of the objectives we set at the start of COP26. First, to get commitments to cut emissions to keep within reach the global warming limit of 1.5 degrees. Second, to reach the target of $100 billion per year of climate finance to developing and vulnerable countries. And third, to get agreement on the Paris rulebook. This gives us confidence that we can provide a safe and prosperous space for humanity on this planet.’

The NGO Greenpeace said in a statement: ‘While the COP26 deal doesn’t put the 1.5C goal completely out of reach, the governments and companies that obstructed bold action on climate change are knowingly endangering whole communities and cultures for their own short-term profits or political convenience. History won’t judge them kindly for this.’

While the final Pact has not reflected the hopes of many, it can be said that COP26 wasn’t short of a desire to see change. Perhaps the surprise package of the two-week event was the declaration between China and US which states that the countries ‘…recognise the seriousness and urgency of the climate crisis. They are committed to tackling it through their respective accelerated actions in the critical decade of the 2020s, as well as through cooperation in multilateral processes, including the UNFCCC process to avoid catastrophic impacts.’ The declaration from the two countries was widely welcomed.

Methane emissions and ocean protection

Other notable developments from COP26 included: The formal launch of the Global Methane Pledge led by the US and the European Union. The Pledge, which seeks to reduce overall methane emissions by 30% below 2020 levels by 2030, saw 100 countries, representing 70% of the global economy and nearly half the global methane emissions, sign up.

In agriculture, the Agriculture Innovation Mission for Climate (AIM4Climate) was launched. Initiated by the US and United Arab Emirates, with endorsement from the COP26 Presidency, the goal of the initiative is to increase and accelerate global innovative research and development on agriculture and food systems in support of climate action.

The initiative has the backing of 32 countries. In addition, ocean protection received a boost with the UK Government using the COP26 Ocean Action Day to announce a wave of investment including at least £20 million in commitments made at the Ocean Risk and Resilience Action Roundtable to drive the health and resilience of the oceans and climate vulnerable communities.

The Science and Innovation day at COP26 saw the launch of four initiatives, backed by global coalitions of nations, businesses and scientists. In what was said to be a global first, the Adaptation and Research Alliance was launched. The network of more than 90 organisations will collaborate to increase the resilience of vulnerable communities most impacted by climate change.

In further developments the UK, along with several countries including Canada and India, will collaborate to develop new markets for low carbon steel and concrete. The work is being carried out under the Industrial Deep Decarbonisation Initiative.

The need for innovation

Commenting on this, George Freeman, the UK Minister for Science, Research and Innovation, said: ‘Real change to combat climate change cannot happen without new scientific ideas, innovation and research, and it is clear no country or company acting in isolation can deliver the change that is needed at the pace that is needed.’

While the final COP26 Glasgow Climate Pact has disappointed many, there is no doubt that there is a will to make positive change, keep global temperatures in check and see humanity reap benefits.

Sustainability & Environment

A group of inspiring young scientists took centre stage at COP26 on 4 November to show how the next generation of chemists is finding tangible climate change solutions.

In a day dominated by what countries pledged to stop doing at COP26, such as pursuing coal power and financing fossil fuel projects overseas, it was refreshing to learn about low-carbon technologies and the young people driving their development. At the Next Gen forum, we heard from an array of young chemists, all associated with SCI, who are at the sharp edge of this change.

We heard from Brett Parkinson, Senior Engineer of Low Carbon Fuels and Energy Technologist at C-Zero, who is working on commercialising a way to decarbonise natural gas. The California-based company’s technology converts the natural gas into hydrogen and solid carbon to provide a clean energy source while sequestering the carbon; and the aim is to have this process up and running next year.

Natasha Boulding is building towards Net Zero a different way – with a greener concrete. The CEO and Co-founder of Sphera has developed a lightweight carbon negative additive using waste plastics that aren’t currently being recycled. She says the company’s blocks are the same strength and price as existing concrete blocks, but with 30% more thermal insulation. There is also the added benefit of reusing waste materials that would otherwise have gone to landfill or been incinerated.

Another solution discussed by Dominic Smith, Process Development Engineer at GSK, reduces energy consumption through green chemistry. He is trying to find greener ways to make medicines using enzymes. These enzymes, which can be found in plants and soil, replace chemical synthesis steps to cut energy consumption during processing and reduce hazardous waste.

Panel (left to right): Dominic Smith, Natasha Boulding, Clare Rodseth, Jake Coole, Nikita Patel, and Oliver Ring (Brett Parkinson spoke via video link).

It was apparent from the discussion that many solutions will be needed for us to reach our climate change targets. On the one hand, Jake Coole, Senior Chemist in Johnson Matthey’s Fuel Cells team, is working on membrane electrode assembly for hydrogen fuel cells to help us transition to hydrogen-powered buses and trucks.

At the same time, Clare Rodseth, an Environmental Sustainability Scientist at Unilever, has been using lifecycle assessments to reduce the environmental impact of some of the 400 Unilever brands people use all over the world every day. For example, this work has helped the company move away from petrochemical ingredients in its home care products. ‘Even small changes,’ she said, ‘have the potential to bring about large-scale change.’

Incremental change

However, for each of the technologies discussed, barriers remain. For Coole and co., having a readily available supply of hydrogen and charging infrastructure will be key. And for Dominic Smith and his colleagues, the use of enzymes in green chemistry is still in its infancy; and getting enzymes that are fast enough, stable enough, and produce the right yield is difficult. Nevertheless, he noted that manufacturers are now using enzymes to produce the drug amoxicillin, reducing the carbon footprint by about 25%

And some things will take time to change. Natasha Boulding noted that concrete is the second most used material in the world after drinking water, and we simply can’t create many green technologies, such as wind turbines, without concrete foundations.

She said the construction industry is quite traditional but also pointed to perceptible change, with the green concrete market growing and companies becoming increasingly aware of their carbon footprints.

Collaboration was seen as crucial in producing climate change solutions.

The reality is that global action on climate change is recent. As Brett Parkinson said: ‘the main reason we’re talking about it now is that there’s a driver to do it. Until the last decade, the world hadn’t cared about CO2 emissions. They just talked about caring about it.’

How pivotal is science in all of this?

So, what could be done to make climate action more effective? For Parkinson, effective policy is key. He argued that if the market isn’t led by policies that encourage low-carbon innovations, then it won’t work as needed. ‘It all starts with effective decarbonisation policy,’ he said. ‘Legacy industries are very resistant to change. If you don’t have strong and consistent policies… then they’re not going to adapt.’

Another key to our low-carbon evolution is collaboration, and the SCI provides a confluence point for those in industry and academia to work together to produce innovative, low-carbon products. As Clare Rodseth said: ‘Collaboration is really important – linking up people who can actually come together and address these problems.’

As the discussion came to a close, you had the impression that the debate could have gone on for much longer. ‘Hopefully, we’ve demonstrated that there is action, and it’s being driven by young people like our panellists today,’ summarised Oliver Ring, the event’s co-Chair, before asking for the result of the audience poll.

The question: How many of those watching believed that science is pivotal in providing climate change solutions? 

The answer: Just the 100%.

This Thursday at COP26, an inspiring panel of young scientists will discuss innovations that will help us mitigate climate change. So, what can we expect?

Millions of young people are frustrated by climate change inaction. Indeed, according to a University of Bath study, 60% of the next generation feel overwhelmed by climate anxiety. Often, the proposed solutions seem vague and intangible – well-intentioned ideas that drift away when the political winds shift.

And yet, when you see the ingenuity of young scientists, business people, and activists, it’s hard not to be excited. Undoubtedly, politics and our legal system will play a huge role in the drive to reach Net Zero, but arguably science will play the biggest role in transforming the way we live. Just think of the falling cost of generating solar power, improvements in battery chemistry for electric vehicles, the development of sustainable construction materials, and the rapid rollout of Covid-19 vaccines.

Tangible solutions

This Thursday at COP26, SCI will host the Next Gen youth forum event where the panellists discuss the climate change solutions they are working on right now and how they are being applied by industry. In the Countdown to Planet Zero roundtable, these scientists – drawn from within SCI’s innovation community – will explain their work to a global audience and the impact it will have on climate change.

They will discuss innovation in three key areas: topics of fuels of the future, turning waste into gold, and engineering nature.

The next generation has mobilised and is creating solutions to help avoid climate change disaster.

The panel will be chaired by two very capable young scientists. Oliver Ring is Senior Scientist at AstraZeneca’s large-scale synthesis team and Chair of SCI’s Young Chemists’ Panel, and passionate climate advocate Nikita Patel is a PhD student at Queen Mary University of London’s Centre of Translational Medicine and Therapeutics and STEM Ambassador for schools.

The other panel members include Clare Rodseth, of Unilever’s Environmental Sustainability Science team, who brings lifecycle analysis to product innovation to make products more sustainable.

Jake Coole, Senior Chemist in Johnson Matthey’s Fuel Cells team, is involved in the scale-up of new processes and next generation manufacturing, and Dominic Smith, Process Development Engineer at GSK, who is interested in engineering biology to create sustainable manufacturing processes.

Also present will be Dr Brett Parkinson, Senior Engineer of Low Carbon Fuels and Energy Technologist at C-Zero – a California-based startup that works on the decarbonisation of natural gas. In 2019, Brett was awarded an SCI scholarship for his research.

The lineup also includes Dr Natasha Boulding, CEO and Co-founder of Sphera Limited, a speciality materials company that has created carbon negative concrete blocks made from aggregate including waste plastic. According to Natasha, whose company also won SCI’s Bright SCIdea challenge in 2019: “In terms of combating climate change, interdisciplinary collaboration is the key. No one discipline has the answer to solve our biggest challenges – but together diverse minds can.’

When you live in a cold country, you think of hot days as a blessing. Air conditioning units are for those in far-away places – humid countries where the baked earth smell rises to meet you when you step off the plane.

But cooling comes at a cost. According to the UN Environment Programme, it accounts for 7% of global greenhouse gas emissions. Some of us are visual learners; so, the sheer cost of cooling really hit me when I stared up at an apartment building in Hong Kong with hundreds of air conditioning units perched above the windows like birds.

And it isn’t just the Hong Kongers feeling the heat. The cooling industry as a whole is under pressure to cut its greenhouse gas emissions. The International Energy Agency expects emissions from cooling to double by 2030 due to heat waves, population growth, urbanisation, and the growing middle class. By 2050, it forecasts that space cooling will consume as much electricity as China and India do today.

Air conditioning units cling to a building

All of this was captured by the Cooling Suppliers: Who's Winning the Race to Net Zero report released by the Race to Zero campaign, the Kigali Cooling Efficiency Program (K-CEP), Carbon Trust and other partners in the UN Environment Programme-hosted Cool Coalition.

This report's authors found that only five of the 54 cooling companies they assessed have committed to net-zero targets. The document outlines three areas that must be addressed on the Cooling Climate Pathway: super-efficient appliances, ultra-low global warming refrigerants, and the widespread adoption of passive cooling measures such as clever home design and urban planning.

So, while builders adjust window sizes, introduce trees for shading, and choose materials (such as terracotta cooling systems) thoughtfully to temper the sun’s gaze, others are availing of different methods.

For example, the COP26 (the 2021 UN Climate Change Conference) Champions Team has just released its Net Zero Cooling Action Plan that includes a Cool Calculator tool to help companies and governments run simple calculations to see where they could decarbonise their cooling systems. Similarly, the UK's Environmental Investigation Agency (EIA) has launched a net-zero cooling product guide that showcases energy-efficient products run on natural refrigerants.

SCIblog 1 April 2021 - The Cool Coalition feels the heat - image of building green walls

Green walls are one of many passive cooling approaches used to reduce our reliance on mechanical systems.

However, it’s clear that the softly-softly approach won’t suffice. The EIA has called on governments to do more to encourage organisations to adopt sustainable cooling, to make concrete policy commitments, and speed-up the phase-out of climate-warming refrigerants such as hydrofluorocarbons.

“The development and expansion of net-zero cooling is a critical part of our Race to Zero emissions,” said Nigel Topping, UK High Level Champion for COP26. “In addition to technological breakthroughs and ambitious legislation, we also need sustainable consumer purchasing to help deliver wholesale systems change.”

We all love the technological panacea – innovations that will cure all the climate ills we have inflicted on the world. But the solution will also involve stodgy government regulations and changing consumer habits, and a reliance on the continued fall in renewable power generation.

For those in traditionally cooler climes, it’s no longer someone else’s problem. It was a balmy 22°C in London this week and we’re not even in April yet. So, it’s certainly time to turn up the heat on the cooling industry.
