To combat the climate crisis and secure a safe future below 1.5°C, the world needs to cut emissions of planet-warming greenhouse gasses by 50 per cent within the decade.
For many, ambitious targets such as this can induce a sense of dread and paralysis. But experts say there is a lot we can do as individuals to counter climate change.
Research shows that lifestyle changes could help the planet slash emissions by up to 70 per cent by 2050.
We sat down with Garrette Clark, an expert in sustainable living with the United Nations Environment Programme (UNEP), to learn more about what people and policymakers can do to make sustainable choices to help secure a healthier planet.
Why is it important for people to consider their individual impact on the planet?
Garrette Clark (GC): We’re facing a triple planetary crisis that threatens our survival, so our impact on the natural world is an obvious concern. An increasing number of people know this but tend to avoid acting on it as the problem can seem abstract, they don’t know what to do, and they have more immediate priorities.
How do our choices as consumers impact the planet?
GC: First, we need to understand that consumers are not only individuals. Great drivers of consumption are businesses and governments, who structure and influence the systems that meet our needs. So, it’s important that people make more informed decisions and ask governments and business to take action. UNEP recently launched Act Now: Speak Up, a campaign that showcases how citizens can compel governments and businesses to up their climate game.
What does a sustainable lifestyle look like in 2022?
GC: I think we hear the word sustainable everywhere these days. We think of sustainable living as the positive things we can do in our daily lives to live better. But given the climate, biodiversity and pollution emergencies, we need to be clear on what those actions are and ensure that everyone needs to be taking them.
If someone wants to live more sustainably, where can they start?
GC: UNEP has made this super easy with the Anatomy of Action, an online media tool which translates the science into action. It all comes down to five domains: food, mobility, stuff, money and fun. In each of those areas, the top three things people could do are highlighted. Now they can be different depending on where and how they live and resources available, but within these three priority actions, there are opportunities for people to take action.
People around the world are talking about what’s known as the 1.5°C lifestyle, a way of living that aims to keep alive the Paris Agreement goal of limiting global warming to 1.5ºC, considered a red line for the planet. Can you tell us more about that ethos?
GC: The 1.5°C lifestyles idea is tied to evidence and what we know about how individuals, governments and business consume. We know we have to change our consumption in the areas of food, mobility, housing and leisure, and we need to change quickly and drastically. 1.5°C living is a guide for change.
How do you convince someone to change the way they live?
GC: In general, people don’t think about how they impact the planet – positively or negatively – and will tend to act if something is easy, accessible, affordable and attractive. That’s why government and business, who are better placed to make systemic changes, are critical to making sustainable living the default option.
What will it take for sustainable living to become the norm?
GC: In addition to the affordability, accessibility and attractiveness of sustainable goods and services, there must be a broader integration of sustainable living into cultural norms so that people don’t think about it as being special but just as the way it goes. If sustainable living practices were featured more in the media stories we’re exposed to, they would become the standard.
What’s one example of that?
GC: If in TV series and movies we saw more vegetarian protagonists eating right-sized meals of tasty, plant-based dishes, swapping proteins would be normalized and desirable. Making sustainable living the new normal means looking at the forces that influence and shape our aspirations and behaviors and integrating sustainability into them.
Some people might wonder: Why should I make sacrifices if my neighbour isn’t?
GC. To counteract the others-don’t-act-why should-I? attitude, all the actors involved — businesses, governments and civil society —should be aligned on the impactful actions to be taken. The evidence is there. The challenge is to enhance understanding and weave together the multitude of actions in a concerted fashion to harness the power of people for change.
GHG emissions from pyrolysis are nine times higher than in mechanical recycling
New study published today by Zero Waste Europe (ZWE) finds that greenhouse gas emissions from pyrolysis of plastic packaging are nine times higher than that of mechanical recycling. The “Climate impact of pyrolysis of waste plastic packaging in comparison with reuse and mechanical recycling” study is based on the estimated future recycling content targets in plastic packaging.
BACKGROUND: In the context of the revision of the Packaging and Packaging Waste Directive (PPWD), the European Commission (EC) assigned the independent consultancy Eunomia to consider the possible introduction of recycled content targets for plastic packaging by 2030. Based on the estimated future recycling content targets in plastic packaging, Eunomia determined to recycle quantities that must come as outputs from chemical recycling or mechanical recycling. Chemical recycling, in this case, means thermo-chemical (i.e. pyrolysis) recycling.
With this study, commissioned by ZWE and Rethink Plastic alliance to Öko-Institut, we calculated the impact of Eunomia’s proposed scenario regarding greenhouse gas (GHG) emissions and carbon loss. The study compares seven scenarios to meet the projected recycled content target by 2030, and puts them into perspective with the Paris Agreement commitments to limit global warming to 1.5 degrees Celsius.
The study found that:
- Pyrolysis GHG emissions are nine times higher than those in mechanical recycling – in all scenarios considered over 75% of greenhouse gas emissions are attributable to chemical recycling;
- Over half of the carbon content of plastic is lost in the pyrolysis process and has to be replaced by new plastic;
- Mechanical recycling must be prioritised over pyrolysis wherever possible – shifting 30% of the production attributed to chemical recycling by Eunomia to mechanical recycling would reduce GHG emissions by 31%;
- Combining shit to more mechanical recycling together with a reduction of 20% of packaging would result in a 45% reduction of GHG emissions compared to the “chemical recycling scenario”.
- Combining mechanical and chemical recycling to transform plastic waste into recyclate avoids the GHG emissions associated with the use of primary plastic.
ZWE’s Chemical Recycling and Plastic-to-Fuel Policy Officer, Lauriane Veillard says: “The revision of the PPWD should serve as a lever to make the packaging sector more circular and be in line with European climate commitments to limit Global Warming to 1.5 Degrees Celsius. There are other ways than pyrolysis for contact-sensitive materials. The climate impact of the managing pathways should be considered when setting targets. The revision is the opportunity to rethink the overall volume and the use we make of plastic packaging.“
With this in mind, ZWE urges the European Commission (EC) to consider the reports’ findings in the upcoming revision of the PPWD and to:
- Introduce legal safeguards to prioritise mechanical recycling over pyrolysis;
- Consider the climate impact of different recycling technologies when settings targets for recycled content;
- Incentivise measures such as design for recycling and innovations along the plastic packaging value chain to facilitate mechanical recycling.
Lauriane Veillard adds: “If we are serious about achieving net-zero emission economy, mechanical recycling must be preferred over pyrolysis. However, this cannot be achieved unless legal safeguards as part of the P&PWD revision are introduced to prioritise mechanical processes for recycling packaging waste complemented with ambitious prevention and reuse targets”.
UN spotlights transformational potential of family farming for world food supply
A Global Forum highlighting the UN’s Decade of Family Farming (UNDFF) got underway on Monday, aimed at identifying priority policies to boost support for family farmers and agricultural development worldwide.
FAO Director-General QU Dongyu, pointed out in his video address to the Global Forum’s opening that the world is moving backwards in its efforts to eliminate hunger and malnutrition.
He said the number of people facing hunger increased in 2021, and it risks rising further especially among the most vulnerable, of which almost 80 percent live in rural areas and are small-scale, family farmers.
Family farmers around the world are also subject to the new challenges to food systems everywhere, created by the climate crisis, as well as conflict. The war in Ukraine has added further pressure, to already fragile agrifood systems, UN agencies said.
Mr. QU said the forum provides a way, firstly, to discuss “the unique role of family farmers in transforming our agrifood systems; two, take stock of achievements and challenges in the implementation of the UN Decade; and three, strengthen collaboration to ensure global food security, enhance livelihoods and achieve the Sustainable Development Goals”.
“Family farmers need to be at the centre of efforts to transform agrifood systems if we are to make real progress towards ending hunger,” Mr. Qu said.
He added that “family farming is the main form of agriculture in both developed and developing countries and is responsible for producing 80 percent of the world’s food,” in terms of value.
He noted that often, these family farmers struggle to feed their own families.
Since its launch three years ago, the UN Decade of Family Farming has been promoting integrated policies and investments to support family farmers, and FAO has been assisting national implementation of international tools and guidelines to strengthen family farming, Mr. Qu told the virtual forum.
He also noted that FAO hosts the Family Farming Knowledge Platform to facilitate the exchange of experience, innovation and specialised knowledge.
In addition, the FAO Strategic Framework 2022-31 includes a priority area of work aimed at better supporting small-scale food producers and delivering concrete results.
Push for the future
The main objectives of the Global Forum are to provide a general overview of policy trends and the relevance of family farming to the global push towards reaching the Sustainable Development Goals; highlight the main outcomes of the first three years of implementation; and re-orient the UNDFF agenda through the practical lessons learned so far.
Participants include representatives from national governments, governmental agencies, UN agencies, family farmers and their organizations, civil society organizations, as well as NGOs; the private sector, the media and academia.
Microalgae promise abundant healthy food and feed in any environment
By Sofia Strodt
Feeding a growing world population that will reach 9.8 billion by 2050, according to United Nations forecasts, and the need to conserve natural resources for generations to come may seem conflicting at first.
But a solution, while not yet in sight, is certainly not out of reach. European scientists recently have developed an appetite for microalgae, also called phytoplankton, a sub-group of algae consisting of unicellular photosynthetic microorganisms.
Most people are familiar with the largest form of algae, kelp or seaweed. It can grow up to three metres long and, in some forms, is a well-known delicacy. The related species microalgae, which can be found in both seawater and freshwater, have gained attention in research due to their extraordinary properties.
These microscopic organisms can be used for animal feed, particularly in aquaculture, and various foods including pasta, vegan sausages, energy bars, bakery products and vegetable creams.
Most commercial microalgae cultivation centres on the production of dried biomass such as chlorella or spirulina powder as a food providing considerable health benefits. Some microalgae strains not only accumulate up to 65–70% of protein but also are sustainable sources of omega-3 fatty acids – a substance that is conventionally derived mainly from fish and fish oil.
Additional bioactive compounds, such as vitamins B12, K or D, mean microalgae contain significant health properties, potentially reducing the risk of cancer and cardiovascular illness.
‘Microalgae can be cultivated in many different locations, under very different conditions,’ said Massimo Castellari, who is involved in the Horizon-funded ProFuture project aimed at scaling up microalgae production. ‘We can grow it in Iceland and in a desert climate.’
The technologies for the intensive cultivation of microalgae have been in development since the 1950s.
Today, microalgae are cultivated in open- or closed-system photobioreactors, which are vessels designed to control biomass production. The closed-system version, while more expensive to build, offers more control over experimental parameters and less risk of contamination.
The substance is by no means just a trendy food supplement. For example, in Chad, a landlocked, low-income country, the consumption of spirulina harvested from Lake Chad has significantly improved people’s nutritional status because spirulina is an excellent source of proteins and micronutrients.
On top of its nutritional value, microalgae offer climate benefits by sequestering carbon dioxide as well as economic advantages by using farming areas more efficiently and – through the use of non-arable land – expanding the possibility of biomass production.
With a total of less than 57 000 tonnes cultivated in 2019, according to the UN Food and Agriculture Organization (FAO), production of microalgae is still very much in its early stages. By comparison, primary-crop output was 9.4 billion tonnes in 2019.
Russia’s continuing war in Ukraine has highlighted just how vulnerable global food supply can be. Halts to Ukrainian grain exports and increases in energy prices have helped push food inflation around the world to record highs, with developing countries being hit disproportionately hard. In May this year, costs for food had risen by 42% compared with 2014-2016, the UN reported.
Last year, as many as 828 million people were affected by hunger – an increase of roughly 46 million compared with 2020 and a surge of 150 million since the outbreak of the COVID-19 pandemic.
The FAO projects that some 670 million people will still face hunger by the end of the decade.
While the benefits of cultivating organic microalgae for food and feed are substantial, market growth will require overcoming obstacles including a lack of automated production in the industry, according to Castellari, who works at the Institute of Agrifood Research and Technology in Barcelona, Spain.
‘The automatisation is still not completely implemented,’ he said. ‘There are small producers in Europe – many steps still involve manual labour. So they are still working on optimising the process.’
The challenges go well beyond cultivation. With microalgae, biomass has to be processed, cleaned and dried before a usable powder can be obtained. The next step is to scale up production to drive down costs.
In addition, there are regulatory challenges. Only a few species of microalgae are currently authorised in the European Union.
‘In Europe it’s still in a preliminary stage of development,’ said Castellari. ‘There are thousands of species of microalgae, but for food consumption or feed there are only seven species authorised.’
To gain knowledge about the possibilities to use other species, Castellari and his team are also investigating these other kinds of microalgae.
Due to these challenges, the portfolio of products containing microalgae remains limited today. But, if these hurdles can be overcome, the overall prospects for the microalgae industry are promising. Besides being a source of food and feed, the plant can be used for biofuels, cosmetics, fertiliser and health supplements.
Astaxanthin, a blood-red pigment extracted from algae, already has notable uses. A powerful antioxidant, astaxanthin can be found in seafood and is commonly used to colour shrimp. It is also sold in the form of pills as a food supplement.
Astaxanthin is thought to have potentially a positive impact on brain function, athletic performance and ageing skin, among other things.
Matteo Ballottari, associate professor of biotechnology at the University of Verona in Italy, helped start the European Research Council’s Horizon-funded project AstaOmega simultaneously to produce astaxanthin and omega-3 fatty acids in microalgae for aquaculture and human nutrition.
Quality and quantity
Most omega-3 supplements are derived from fish oils. This, however, raises sustainability concerns such as damage to marine ecosystems as a result of overfishing.
‘There is more demand for eating high-quality foods, along with an awareness for incorporating omega-3 rich ingredients in our diets,’ Ballottari said. Responding to this trend while feeding a growing world population is ‘a big challenge,’ he said.
Meanwhile, on the astaxanthin front, the AstaOmega researchers have made progress. They have been able to obtain a new strain that can produce astaxanthin on its own, without needing to be “stressed”. This means the researchers don’t have to change production parameters such as light intensity, temperature or nitrates concentration. Also, extracting the substance has become easier, resulting in lower costs.
Scientists agree that microalgae have the potential to change the ways in which we eat for the better.
‘Microalgae can help us to increase the protein production within Europe to reduce our dependence on other countries,’ said Castellari of the ProFuture project.
