The Low Carbon Chinatown Digital Cookbook is a digital companion piece to Low Carbon Chinatown, a project by Ling Tan.

Carbon Footprint Impact Of Food
食物的碳足迹影响

The data below shows the carbon footprint rankings of ingredients, food sources and cooking methods that are often used in popular Chinese dishes such as Chicken Rice, Sweet and Sour Pork and Wonton Dumpling Soup. Working with data scientist, Raphael Leung, the data were gathered to encourage participants involved in the Low Carbon Chinatown Workshops to think of inventive ways to reduce their meal’s carbon footprint. Click on the different buttons to explore the various carbon footprint information.

Carbon footprint data used here draws from several sources and is meant simply to provide a general understanding of relative impact.

Carbon Footprint Ranking | 碳足跡排名

All carbon footprint units are kgCO2eq per kg unless otherwise specified.

Protein | 肉类

1 portion of beef fillet steak | 牛肉 (90g) Highest | 最高

1 portion of lamb meat | 羊肉(90g)

1 portion of prawns, frozen | 冷冻虾(90g)

1 portion of salmon fillet, frozen | 冷冻鲑鱼 (140g)

1 portion of pork chops | 猪排 (90g)

1 portion of duck |鸭肉 (90g)

1 portion of chicken |鸡肉 (90g)

1 portion of tofu | 豆腐 (100g) Lowest | 最低

This approximate comparison uses carbon footprint per 1 portion of food ingredient. Generally speaking, the protein will be among the highest carbon footprint food items on the plate, by a large margin. Note that body part, type of processing, and cooking method may change the footprint – e.g. beef ribeye has a higher footprint than beef sirloin; pork bacon is higher than pork mince. Source: Portion sizes from Association of UK Dietitians aggregated by FT Carbon Food Labeling, carbon footprint per portion from the same source. Duck value from the Chinese Food LCA database/ Cai et al. 2022.

Vegetables | 蔬菜类

1 portion of tomatoes | 番茄 (80g) Highest | 最高

1 portion of bamboo shoots | 竹笋 (80g)

1 portion of mushrooms | 蘑菇(80g)

1 portion of carrots | 萝卜(80g)

1 portion of onions | 洋葱(80g)

1 portion of cabbage | 卷心菜 (80g)

1 portion of cauliflower | 菜花 (80g) Lowest | 最低

This approximate comparison uses carbon footprint per 1 kg of food ingredient, though one portion is rarely 1 kg. Generally speaking, the vegetable will be among the lowest footprint food items on the plate, though not as low as any starches. E.g. Steaming tomatoes on the hob, the highest footprint way of cooking them, is still more than ten times lower in total footprint per kg than slow cooking beef, the lowest footprint way of cooking beef. Source: Portion sizes estimated from FT Carbon Food Labeling, carbon footprint from pre-consumption values Frankowska et al. 2020; the Chinese Food LCA database/ Cai et al. 2022 for bamboo shoots value.

Starch | 淀粉类

1 portion of cooked white rice | 未煮过的白米饭 (200g) Highest | 最高

1 portion of boiled potato | 煮土豆 (120g)

1 portion of uncooked Brown rice | 未煮过的糙米 (75g)

1 portion of uncooked wheat flour | 面粉 (120g)

1 portion of uncooked Glutinous rice | 未煮过的糯米 (75g)

1 portion of uncooked Egg Noodles | 生鸡蛋面 (50g)

1 portion of steamed plain bun | 蒸馒头 (50g) Lowest | 最低

This approximate comparison uses carbon footprint per 1 kg of food ingredient, though one portion is rarely 1 kg. Generally speaking, the starch will be among the lowest carbon footprint food items on the plate. Note that the cooking method may change the footprint – e.g. stirring dried potato powder and hot water will increase footprint to be as high as polished rice. Source: the Chinese Food LCA database/ Cai et al. 2022 for cereals comparison (the academic term for rice, noodles, bread etc) comparison, we used steamed bread value for steamed plain bun, and polished rice for white rice; Frankowska et al. 2020 for cooked white rice (using electric pressure cooker for cooked) and potato values; and Xu et al. 2020 for potato vs rice comparison.

Seasoning | 调味料

1 teaspoon (4.2g) of palm oil Highest | 最高

1 teaspoon (4.2g) of olive oil

1 teaspoon (4.2g) of sunflower oil

1 teaspoon (4.2g) of soy sauce

1 teaspoon (4.2g) of sugar Lowest | 最低

Sources are CarbonCloud for soy sauce in glass bottle, Poore et al. 2018 for oils, and Cai et al. 2022 for sugar.

Carbon footprint data used here draws from several sources and is meant simply to provide a general understanding of relative impact. | 這裡使用的碳足跡數據來自多個來源，只是為了提供對相對影響的一般理解。

On Farmed Vs Wild-caught Fish | 养殖与野生捕捞的鱼

• Farmed fish on average may be a little bit lower, but it's not conclusive whether a fish has a higher/lower footprint just purely if wild-caught vs farm-raised.

• The main cause of carbon footprint for fish farming is feed, whereas for wild caught it is fuel eg ships.

• Wild-caught is a really wide category, so the confidence bands are high-- so I imagine the lowest would be hook and line from a local fisherman, and highest would be a fishing tanker.

• Generally speaking, farmed salmon very likely has less footprint than chicken, whereas wild salmon may also have less footprint than chicken but this is less certain. Depends on what type of wild.

• Source is Fig 1 from Gephart 2021 (5.1 kgCo2eq/kg for farmed salmon and 6.9 for wild -- the beige band is chicken). Their method is simplified LCA.

Carbon footprint data takes into account operational costs to run a supermarket. Dedicated online retailers can store and deliver food more efficiently, reducing last mile emissions. However, going to your local store by foot or bike can have the same effect. Carbon footprint data used here draws from several sources and is meant simply to provide a general understanding of relative impact.| 碳足跡數據考慮了經營超市的運營成本。專門的在線零售商可以更有效地儲存和運送食物，減少最後一英里的排放。但是，步行或騎自行車去當地商店也有同樣的效果。這裡使用的碳足跡數據來自多個來源，只是為了提供對相對影響的一般理解。
On Food Source | 关于食物的来源

• Scientific consensus has been that food transport is not a major contributor to emissions, compared to what you eat eg Poore 2018 and Ritchie's data viz

• Some also argue "food miles" is not a helpful concept -- as it stresses distance, when mode of transport is more important. E.g Same distance by seas is lower footprint than same distance by road (source: Coley 2011)

• More recently, the food miles debate has surfaced again: there is a Nature food paper 2022 which is "a significant deviation from the former scientific mainstream opinion that transport is no major contributor to emissions from the food system"

• They measures food miles in a different way: looks at transport of "everything upstream, from fertilisers to pesticides to machinery" (twitter thread from Ritchie)

• main suggestion from that lead author: eat local/ seasonal ("localising food supply still leads to emissions reductions”, but adds: “For consumers, in addition to shifting towards a plant-based diet, eating local seasonal alternatives is ideal, especially among affluent countries.” source: carbonbrief)

• Food miles is a useful data point (frequently printed on labels), but what matters as much is the mode of transport. The same distance by air incurs the highest footprint, followed by sea, then road (HGVs) and finally local food has the lowest footprint. Eat local, eat seasonal if you can! Source is Coley 2011.

Carbon footprint data used here draws from several sources and is meant simply to provide a general understanding of relative impact. This approximate comparison uses the carbon footprint contribution, per kg of cooked food, that cooking is responsible for, taking into account cooking time for the type of food. Generally, if the cooking appliance has an option between hob and electric – e.g. steamer, pressure cooker, deep fry – the hob version would incur higher footprint than electric. Source: Frankowska et al. 2020

On Gas Vs Electricity Hobs | 燃气灶与电灶

• Gas is slightly cheaper £17/yr, electric hob is £40/yr if you run it 5 hrs a week (source: Which? September 2022)

• but electric hobs are easier to clean, distribute more even heat, and gas is becoming more expensive

• gas is "cleaner than coal, but still bad for the environment", gas hobs may soon be banned from being installed in new UK homes like the Netherlands (source: BBC) smart meters and grid management can reduce running costs of electrical heating (source: ECA)

• gas is "cleaner than coal, but still bad for the environment", gas hobs may soon be banned from being installed in new UK homes like the Netherlands (source: BBC) smart meters and grid management can reduce running costs of electrical heating (source: ECA)

• estimated 49% of UK have a gas hob (source: survey 2020) 46% have an electric hob; whereas 85% have a microwave oven, 50% have a slow cooker, 37% have a electric eg Foreman grill

• right now, the biggest single energy source entering the Grid is still gas (source: National Grid, Sheffield uni energy dashboard).

• Renewables, which excl nuclear, generated 45.5% of electricity in June 2022 (source BEIS gov.uk), the highest record was 47.1% in 2020 Q1 when the UK experienced exceptionally high wind speeds

• the main big actions are around the oven: don't preheat for longer than needed, thaw/defrost food with microwave, only use oven if can be used efficiently (using up different shelves), if you're replacing the hob, go with electric. Also: use a pot lid, cook foods in pots that are full to capacity (sources: various 1,2,3,4)

• cooking is about 6.1% of household energy consumption (source: Eurostat); many actions that cut carbon footprint also save bills.

Low Carbon Chicken Rice By MiMi Aye
低碳鸡饭

Low Carbon Chicken Rice

"Chicken thighs are a good choice, because they are basically a by-product of the more popular chicken breast which means less waste (they’re also cheaper for the same reason). Thighs also cook more evenly and quickly than whole chickens. Some of the ingredients can be home grown, e.g ginger and spring onions"

Key Steps | 关键步骤

For the Chicken Trim any fat from the chicken, plus any skin attached to it and place in a wok or large frying pan. You will use this fat to cook the rice.
Rub the chicken all over with salt to polish the skin, leave for 5 minutes and then brush off and discard as much salt as possible.
Place the chicken in a large saucepan with the spring onions, ginger, sugar and chicken powder, if using.
Fill the pan with enough boiling water from the kettle to just cover the chicken (about 1 l) and place over a high heat. Heating water using a kettle is more efficient than heating it on a stove.
Cover the pan with a lid and bring it to the boil. Let the pan boil vigorously for 5 minutes and then turn off the stove.
Place a clean tea-towel over the lid to seal it tightly and allow the chicken to poach in the residual heat for 30 minutes.
Then remove the chicken and ‘shock’ it in the bowl of cold water for 10 minutes. This lets the chicken skin become glossy and tight.
Remove and discard the ginger and spring onion from the stock and set the pan to one side.
Drain the chicken from the water, remove the bones and then brush or rub the skin with the rapeseed oil. Set the chicken to one side.
For the Rice Render the fat from the trimmings by frying on a high heat for one minute then turn down to medium and fry for another 10 minutes. Remove (and eat) any crispy bits.
Fry the garlic and ginger for 1 minute in the rendered fat until fragrant and golden. Add the rice and salt and stir well to combine. Turn the heat up to high and fry for 4 minutes until the rice ‘pops’.
Transfer everything to your rice cooker. Top up to the ‘2 rice cooker cups’-level with chicken stock and press ‘cook’. A rice cooker is the most energy-efficient way to cook rice.
For the Chilli Garlic Sauce Blend everything together into a smooth paste using a pestle and mortar.
For the Ginger and Spring Onion Sauce Place the spring onions, ginger and salt in a heatproof bowl. Heat the oil in a small pan for 2 minutes until it smokes and then carefully pour onto the spring onion mixture. It should sizzle and cook using the residual heat of the oil.
To Serve Slice one chicken thigh per person and place on a plate with a portion of rice and some cucumbers. Serve with the two dipping sauces. You can also serve any leftover stock on the side as a soup.

Key Steps | 关键步骤

In a large bowl, mix all the marinade ingredients together and set aside.
Mix together all the ingredients for the sweet and sour sauce. Set aside.
Have 3 shallow bowls ready, one for the beaten egg, one for cornflour and one to place the coated cauliflower. Dip a cauliflower floret in the beaten egg, then dredge it with cornflour and tap off any excess flour, then place it in the third bowl and repeat with all the florets.
Bring an electric deep fat fryer to about 170°C (325°F/gas 3). Deep-fry the coated cauliflower for exactly 4 minutes until they turn golden then set to cool on a rack or paper towels. For a crispier affair, double fry, the second time for 2 minutes at 170°C (325°F/gas 3).
In a wok, over a high heat, add the cooking oil. Once it has melted, add the onions to char on the edges and then the garlic. Once the garlic starts to turn golden, throw in the red pepper, courgette and mangetout.
Quickly stir-fry and toss for about 2 minutes then add the pineapple chunks, cook for a further 2 minutes. Mix together then add the sweet and sour sauce. Toss and cook together until it becomes juicy, thick, saucy and glossy. Turn off the heat and add fold in the florets.
Garnish with spring onion. Serve immediately with steamed rice.

Low Carbon Wonton Dumpling Soup

"Instead of usual pork and prawn, we use a vegan filling of tofu, leek and carrot. Tofu’s a super versatile ingredient and takes on flavour like a sponge. Leek, when stir fried first, gives us savoury depth and aroma. Carrot gives us the sweetness and colour you would normally get from prawns. We also use UK made wonton wrappers rather than imported wrappers."

Key Steps | 关键步骤

Place firm tofu under a heavy dish for about 15 minutes, to help remove excess water.
Meanwhile, on an electric stove over medium high heat, fry the leek in sunflower oil until softened, about 5 minutes. Add 1 tablespoon of soy sauce and cook for another 2 minutes until most of the soy sauce has disappeared and been absorbed by the leek. The leek should reduce in volume and also become a bit sticky - helping you bring the filling together.
Drain the tofu and finely chop. Combine tofu with all the rest of the filling ingredients, stirring till well combined.
Dip your finger in water and wet the edge of a wonton wrapper. Place a tablespoon of filling in the middle. Fold the wrapper in half into a rectangle, pressing to seal the edges. Wet one corner then place the other corner on top, press to seal.
In a saucepan, bring the stock to a boil. Season with soy sauce, white paper and sesame oil.
In a separate saucepan, bring plenty of water to the boil, then lower the heat to a medium high. Gently put in the wontons in a single layer (you may need to cook them in batches). Move them around with a spoon to avoid sticking.
The wontons are done when they rise from the bottom and float on the surface, about 3 minutes.
Remove the wontons with a slotted spoon into bowls. Pour over the stock and garnish with the chopped spring onions.

LOW CARBON SALT & PEPPER 'PRAWN' By Leeds Community Members
低碳椒盐虾

Four short cooking-documentary films were developed as part of a Low Carbon Chinatown residency carried out in Leeds (UK) in 2023. The films follow 4 Leeds residents, a 79-year-old immigrant from Hong Kong, a 41-year-old immigrant from China, a 25-year-old university student from China, and a 18-year-old high school student from Hong Kong into their own home environments, where they each cook their own version of a low carbon Salt and Pepper ‘Prawns’ dish in their own kitchen, and talk about their experience living in the UK and their relationship to climate change. The films invite the audience to examine how different age, background, heritage, and life experience affects the way people cook food at home and in tackling the climate crisis.
