WHAT IS NET ZERO FOOD?
The food you are eating right now has been gone through a long process until reaching your plate. From the crop, the farm or even the sea all ingredients have been transported to the food manufacturing site, where they have been processed to become the final product suitable for eating. Once packed, they have been delivered to the store for customers like you to buy them.
This process comprises many different activities like harvesting, breeding, transporting and producing that have a negative impact on the environment. For example, road transport release carbon (CO2e) to the atmosphere and manufacturing plants require energy that may come from non-renewable sources that also emit CO2e and cause air pollution.
As you may know CO2e is one of the main pollutants of the environment and gas behind the greenhouse effect and climate change together with others like methane and nitrous. The sum of all these gas emissions produced by growing, rearing, farming, processing, transporting, storing, cooking and disposing of the food you eat is known as carbon footprint. And the total amount of carbon released to the atmosphere is called embedded CO2e. The further your food comes from and the longer the process to reach your kitchen, the larger your carbon footprint and the higher the embedded CO2e of your food.
Also not all emissions are the same and they are categorized into three groups named “scopes” depending on the origin and control companies have over them.
- Scope 1 – All Direct Emissions, related to fuel combustion and under control of the company
- Scope 2 – Indirect Emissions, linked to electricity purchased and also and under control of the company
- Scope 3 – All Other Indirect Emissions, associated with procurement, transportation and distribution that are not usually under the control of the company and the greatest share of the carbon footprint
The latest category, Scope 3, is by far the most difficult one to calculate. However all of them must be taken into account if we want to know the real total amount of embedded carbon of our plate.
There is no way to take back the gas that has been already emitted to the air so companies can only try to reduce their energy consumption and to offset the carbon they emit. One of the best methods to do this is by planting trees as they capture CO2e and use it to build their trunks, branches, roots, and leaves. By doing this, companies can try to “absorb” from the air the same amount of carbon they have released to manufacture their products.
We can consider as net zero all foods whose total carbon emissions have been calculated in order to sequester them back from the atmosphere and therefore, the impact of their manufacturing process on the environment has been “neutralized”.
WHY SHOULD WE CONSUME NET ZERO FOOD?
Switching the lights off when you leave the room and unplugging your electronic devices when they are not in use are some easy examples of actions you do in your daily life to consume less energy. Also using public transport or commuting by bike are simple ways to reduce your carbon footprint.
Eating net zero food is just other habit you can incorporate in your routine to take care of the environment. We turn on and off several lights every day and we also eat several times per day. If you think about it, we all eat at least three times per day and every day of the year during our entire life so you cannot imagine how many tons of food each human consumes in total and how big is our personal carbon footprint.
For example, eating just a serving of avocado once a day contributes approximately 72kg to greenhouse gas emissions per year. That is the same of driving 297km with a car, heating a home for 11 days or taking 252 showers lasting eight minutes.
You probably were not expecting such a high quantity and we can imagine how shock you must be right now. As you can see consuming net zero food has a much higher positive impact on the environment than you think and can really make a difference in the fight against climate change.

WHERE CAN I BUY NET ZERO FOOD?
Up until now there were no carbon neutral foods available in the market but this has recently changed. We are happy to announce that Alara has become the first manufacturer on Earth to produce net zero food after the launch of our new cereal line including their embedded CO2e on pack.
Our new net zero food cereals are available in four different flavours – Apple & Cinnamon Bircher, Crispy Fruit Muesli, Fruits & Seeds Muesli and Original Muesli – and each of them have also a different embedded CO2e depending on their ingredients.
Our Crispy Fruit Muesli goes first in the ranking as it has 105g per 100g followed by Original Muesli with 79g per 100g, Fruits & Seeds Muesli with 72g per 100g and Apple & Cinnamon Bircher with 62g per 100g.
You can easily check these numbers at the back of each pack:
As you can see these numbers significantly change between these four products. Apple & Cinnamon is the recipe with less carbon emissions while Crispy Fruit Muesli goes first but the reason behind this is easy to understand. Both of them have a similar amount of ingredients but for example, coconut chips in the latest are imported from far away and the main responsible of this difference. The journey of this ingredient to our premises is very long and therefore the amount of carbon needed to arrive here is also much higher in comparison with other ingredients. This is the main reason the total amount of embedded carbon for the same amount of muesli is so different.
Every little ingredient has an impact on the environment as every tiny action we make to fight against climate change does.
HOW DO WE MAKE SURE THESE FOUR PRODUCTS ARE NET ZERO FOOD?
We made a list of the 21 raw ingredients we use in these four new products and a team of tutors and students at Westminster University helped us to research the total embedded CO2e of each of them until leaving our premises.
We were already aware of the Scope 1 and 2 and they helped us to evaluate the Scope 3 so we were finally able to calculate the total amount of embedded carbon both direct and indirect.
We took these numbers and talked to Rainforest Saver, an organization dedicated to promote environmentally-friendly farming techniques amongst Sub-Saharan Africa and Central and South America farmers. Cutting and burning plants, also known as slash-and-burn agriculture, is a widely used method to clear the land to cultivate food, but it causes a huge damage to the environment. Rainforest Saver promotes an alternative farming technique consisting on planting a tree called Inga, which has been proved to maintain soil fertility and good harvests without destroying the forest.
We donate money to Rainforest Saver to promote the Inga alley cropping in those areas so they can help farmers to learn how to plant these trees. By doing this we do not only prevent the forest to be destroyed but also to compensate our carbon emissions as each Inga tree capture an average amount of CO2e during its life.
By comparing our embedded CO2e with the average quantity absorbed by each tree, we can offset all carbon emissions we have generated along the manufacturing process. This way we take back from the atmosphere, all gases we have released before to produce the cereals you have in front of you.
HOW DO OUR CEREALS COMPARE TO OTHER BREAKFAST?
You may believe there is not much of a difference but there is! For example the embedded carbon of a fried eggs and bacon breakfast is the same as leaving a bulb on for 17 hours and having avocado on toast equals to 6.5 hours. However making a porridge with Alara cereals emits as much carbon as switching off the lights of your house, zero.
HOW MUCH CO2e ARE WE OFFSETTING?
Below you can find our monthly report in which we gather the total embedded carbon of these four products according to our sales. We will keep it updated so get back at the end of every month to check how we are doing.
