Why Plastic-Free Isn’t Always Better For the Environment

Why plastic-free isn’t always better for the environment, and how to navigate this minefield.

My post last week on plastic-free toilet paper sent a few of you into a spin, when I found out that in terms of carbon emissions, recycled toilet paper that’s made in the UK/EU and wrapped in plastic has a lower carbon footprint that plastic-free toilet paper shipped from China. That includes the popular brand Who Gives A Crap.

What’s more, a recent study showed that a paper bag has to be re-used four times before it’s more environmentally friendly (in terms of carbon emissions) than a plastic bag, and a reusable cotton bag a staggering 131 before it has a lower carbon footprint (and therefore, lower global warming potential) than a plastic bag.

What this means is that sustainability is a lot more nuanced than just saying plastic is bad; and paper, glass, cardboard, cotton and other natural materials are good.

Similarly, a basket of plastic-free fruit and vegetables that are shipped all the way from Egypt or South America are going to, mostly, have a higher carbon footprint than seasonal UK produce wrapped in plastic, that’s often there in the first place to prolong freshness and prevent food waste. The carbon footprint of packaging is only about 10% of the food we eat. It’s a tricky one to get your head around that less plastic doesn’t always equal better for the environment.

Whilst plastic reduction is a great entry point to sustainability, as plastic is a very visible reminder of our impact on the environment, there’s also a whole lot more at play, and the problem at hand too important to allow plastic to be the limits of our work to reduce our impact on the environment.

Whilst reducing plastic is important for our physical environment, we also need to look at other issues in parallel – such as, in the case of toilet paper or fresh produce, the impact of shipping goods from the other side of the globe, and our consumption patterns and those impacts on climate change.

Not sure what this should look like? The WWF’s Carbon Footprint calculator is a handy guide to show us where we can take the most impactful changes to reduce our individual global warming potential. Note that reducing plastic isn’t on there, but it often goes hand in hand with reducing our consumption of stuff.

The other bigger problem, is that by saying sustainability is all about plastic, then that immediately dismisses and disengages the large percentage of people who due to disability can’t prepare fresh vegetables; or can’t afford the often costlier plastic-free options; or who don’t have access to plastic-free options, such as bulk shops.

By saying that sustainability is all about being plastic-free, then sustainability becomes an unwelcome tool to segregate and divide society, and a big blinking neon beacon of privilege, at a time when we need everyone to work together.

What does this mean in terms of decision making when we need to buy things? How do we navigate this minefield that sometimes plastic is bad and sometimes it’s good?

A single blog post how on how to navigate life would be overwhelming. But I thought that taking one bit of it – the bit I get asked about the most often – food shopping – might be helpful. And there might be lessons we can learn from the food that we buy that we can apply to other aspects of life.

So let me share my approach to lower carbon food shopping in a wholly imperfect food system, and then the lessons from that, that can be applied to life in general:

My Approach to Lower Carbon Food

I’m limited in what produce we can buy because I live in a less well-off area, that has a 35% child poverty level. This means no zero-waste stores, and no Waitrose stores.

The fact that 35% of kids live in poverty upsets me 100% more than the fact that there are no zero-waste bulk shops near me. I’d rather everyone could eat, and didn’t have to rely on food banks, rather than there being a zero-waste shop in our area that only a privileged few could afford to shop at. Wringing my hands over a lack of zero-waste places to shop seems like a privilege too far, so I don’t.

For me to visit a zero-waste shop would necessitate a 24 mile round trip to my nearest zero-waste shop. The time, money and extra fuel involved to do so means I don’t, so this is my approach to low carbon food at the supermarket. I’m not perfect, our food systems aren’t perfect, and your food shopping processes might look different depending on what you have access to, and on your capacity, but let’s give this a go:

Fruit and Veg

I try to buy loose seasonal UK fruit and vegetables in the supermarket. If there are only UK seasonal produce wrapped in plastic then I’ll opt for that because the carbon footprint of the plastic packaging is often (but, for added complication, not always!) far less than that of unpackaged fruit and vegetables shipped from places like Chile.

If there are wonky fruits and vegetables available, then, regardless of where they have come from and how they are packaged, then these are a good buy because these are fruits and vegetables that would otherwise be discarded (i.e. binned) because they are not deemed “perfect” enough for consumers.

With fruit that comes in a bunch, e.g. bananas, I buy the single ones, rather than immediately reaching for the ones already in a bunch. It’s been found that shoppers are less likely to choose single bananas, and these often get left behind and binned. Bananas have a surprisingly low carbon footprint (told you it’s complicated!).

We often buy canned vegetables, such as mushrooms, as we found when we bought fresh mushrooms these often went off in the fridge as we didn’t use them all in time. Now when we make vegan chilli or stew we use a whole can of mushrooms with no food waste.

If you need to opt for pre-prepared vegetables wrapped in plastic because of circumstance then you do that and do not ever feel guilty. Those of us who can prepare fresh vegetables will do the heavy lifting on this one.

Packaged Food

Vegan food packaged in plastic has a significantly lower carbon footprint than meat that you can buy unpackaged from the butcher. Particularly beef and lamb. I try not to buy too much, but vegan soft “cheese” and vegan yoghurt often feature in my shopping trolley.

The reduced section is a great place to buy any food, even meat if you eat it, particularly at the end of a day, because a) it’s generally very cheap and b) if you don’t buy it then it’s probably going to go in the bin. Not composted. Just straight in the bin, where it will create methane, that has a global warming potential that’s around 28 times higher than that of CO2. Of course, it’s only a good buy if you are actually going to eat it. Either make sure you eat it that day or check the label to see if it’s freezable, and freeze and eat another day. If not, leave it for someone else who may appreciate it more.

As a working parents, we don’t always have time or energy to cook every meal from scratch. In the frozen section, a lot of vegetarian and vegan produce comes in cardboard boxes. I like to keep boxes of Quorn vegan fishless fingers to hand, for example, for those evenings.

At the moment I am buying staples such as pasta and rice in plastic because of a lack of other options. I try to buy the biggest bags I can to reduce plastic in that way. Sometimes I find Barilla pasta that comes in a cardboard box, but otherwise, I don’t sweat it.

Other Food & Shopping Tips

Taking my own bags and produce bags* and remembering to use them is super important – remember it takes 131 uses before a cotton bag has less global warming potential than a plastic bag,

Meal planning is king – having an idea of what you are going to cook is a good idea so you only buy what you need.

Repurposing leftovers – having them for lunch the next day or dinner the next evening, or freezing for later, is key to avoiding waste, and saving money. If food waste were a country, scarily it would be the third largest behind the US and China in terms of global warming potential.

With that in mind, getting creative with food-waste is a good idea (including this!) and composting anything unused and leftover, if possible,

We bought a cheap slow cooker* a couple of years ago – this makes cooking from scratch a whole lot easier on the days when we are both at work. We can pop it on in the morning, if we’re not running around like headless chickens trying to get everyone out of the door and to the right place on time, and return home in the evening to a home-cooked meal that’s low on packaging. If there are leftovers then that’s lunch for the next day, or a meal for the freezer.

I’m not always the best at this, but following on from this, taking lunch to work means I can make something vegan (vegan takeaway options can be hard to find in the town where I work), and save on packaging.

I’m sure there are a hundred thousand other tips on low carbon foot and eating. It’s easily a subject for an entire book, but this is my general philosophy towards food.

Key Lessons

How this discussion on food fits in to the wider issue of environmentalism is that I hope it shows how a bit of pragmatism is needed, and this pragmatism can be applied to all aspects of life:

  • Consuming only what we need is probably the biggest thing we can do, in all aspects of life, to be more sustainable.
  • Thinking about where an item has been made and shipped from and the emissions involved is an important consideration. This can be complex – I found this book* incredibly helpful.
  • Plastic-free doesn’t always mean better – it’s a great place to start but our environmental activism can and should extend beyond just a focus on plastic.
  • This doesn’t give us carte blanche to go mad on plastic – reducing plastic where we practically can is still important because of it’s impacts on the physical environment and marine life.
  • Reusing what we have and reducing waste, particularly food waste, is incredibly important and should not be underestimated.
  • Just because something doesn’t look perfect doesn’t mean it’s not valuable.
  • Remember that not everyone has equal access/opportunities/abilities so everyone’s actions will look different.

It’s certainly all food for thought but I hope that these tips will guide you through any purchasing decisions.

Maybe you have any other tips you would add? Maybe you have some you disagree with? Maybe I’ve fried your brain? Either way, let’s chat!

Ten Things

Hello! Having a good weekend? I’ve had a busy one at work – evening and weekends this week – so I’m just going to jump straight in if you don’t mind me:

This week’s links:

1. New Zealand has just abandoned economic growth or other growth indicators as a political priority, in favour of well-being. Billions of pounds will be spent on mental health services, child poverty, homelessness and domestic violence.

This is absolutely huge news. In the UK we are pursuing economic growth at all cost – economic growth is used as a justification for everything, from additional runways to increased road building. Meanwhile the Government are pushing wellbeing further and further down the agenda. Neither of these aspects are in any way sustainable, and we could learn a huge amount from New Zealand’s lead on this.

2. What do the plastics and climate crises have in common? The same someone profiting from the status quo.

Whether it be the fossil fuel industry or the broader petrochemical industry, the corporations profiting from the problem have been reluctant to envision a future where they could profit, instead, from the solutions to the problem.

While governments, various private-sector actors and private citizens have joined forces in an effort to find alternatives to single-use, plastics manufacturers have been largely AWOL. In fact, they’re increasing production“.

3. That status quo is clearly hurting poorer communities. This week it has been reported that Malaysia is to return 3,000 tonnes of contaminated plastic waste to the countries that sent it there, including the UK, after being deluged with so much waste that their recycling systems have been overwhelmed. Rubbish has often been dumped or discarded, only to end up as marine litter.

The environment minister, Yeo Bee Yin, said that “garbage is traded under the pretext of recycling [and] Malaysians are forced to suffer poor air quality due to open burning of plastics which leads to health hazard, polluted rivers, illegal landfills and a host of other related problems.”

4. Every protest shifts the world’s balance. An eloquent reminder on why our actions matter.

People taking such stands have changed the world over and over, toppled regimes, won rights, terrified tyrants, stopped pipelines and deforestation and dams. They go far further back… to the great revolutions of France and then of Haiti against France and back before that to peasant uprisings and indigenous resistance in Africa and the Americas to colonisation and enslavement and to countless acts of resistance on all scales that were never recorded“.

5. Britain has now gone two weeks without coal.

6. Mexico has a new environment minister, and I like the cut of his jib.

“Human beings are not responsible for global warming, as superficial environmentalism and uncritical science would like to tell us… The responsible are a parasitic and predatory minority, and that minority has a name: neoliberalism.”

7. After last week’s radical plan to save the planet by working less, here’s a further case for working fewer hours: each bank holiday saves at least 100,000 tonnes of carbon emissions.

8. Supporting this campaign from Which? on Freedom to Pay, which highlights the many people and industries that are affected by a society moving away from cash payments. 

9. The Indian school that accepts plastic waste instead of school fees.

10. Finally, new podcast alert – Big Closets, Small Planet is a new podcast series that seeks to explore what it will take to transform the fashion industry so that it contributes positively to the lives of people and the health of the planet.

Have a great Sunday!
