What is a food carbon footprint?
Food carbon footprint pertains to the total amount of greenhouse gas emissions generated throughout the entire life cycle of a specific food product. This includes every stage, from the cultivation of ingredients and the manufacturing process to transportation, distribution, and even the eventual disposal of food waste. Greenhouse gases, such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), are released at various points in this life cycle.
By calculating your food carbon footprint, you can gain a quantifiable understanding of the environmental impact of your dietary choices. BBC’s Calculator or the Plate Up for the Planet are some online tools that can help you quantify your food carbon footprint.
When using these tools, you can input specific details about your dietary habits, food choices, and consumption patterns. These details may include information about the types and amounts of food you regularly consume, as well as the sources of your food, whether they are plant-based or animal-derived. The calculators then generate estimates of the associated carbon footprint, offering insights into the environmental impact of your food choices. They may highlight the emissions associated with the production and transportation of certain foods, providing valuable comparisons between different types of food and helping you identify options with lower environmental impacts.
It’s important to note that while these calculators offer practical guidance and valuable insights, they provide rough estimates. The actual environmental impact can vary due to factors like regional differences in production methods, transportation efficiency, and waste management practices. Despite these variations, these tools serve as practical guides, allowing individuals to make more informed decisions about their dietary choices and encouraging a greater understanding of the potential effects associated with different foods.

How are clean air zones viewed around the world?
Cities all around the world are battling against high levels of pollution and particulates,? produced by a large variety of human activities; these span from vehicle and industry emissions to agriculture and home heating. Exposure to this pollution, particularly that of vehicles, has been found to cause many health problems such as respiratory diseases as well as increasing the risk of a stroke or lung cancer.
A popular solution to the detrimental effects of city congestion and pollution has been through government intervention, with the implementation of policies such as low-emission zones (LEZs) and congestion charging zones (CCZs). These are zones that restrict or charge for the use of certain vehicles within designated areas, typically older or more polluting cars.
Scientific research has shown that the use of these clean air zones can be advantageous with regard to reducing pollution-related health problems. They found that in cities where there are LEZs, there were some instances where this reduced the cases of cardiovascular diseases and hospital admissions.
These clean air zones have been used by governments all around the world, with each and every country using a variety of techniques and methods to reduce emissions. Data gathered from a group of ministries reveal that Europe has a significant number of these zones already in place in their cities. Have a look at what kind of low-emission zone restrictions there are in European cities. Here are some more in-depth examples of low-emission zones and how they work:
The Netherlands: In January 2015, the city of Rotterdam implemented a LEZ which applied a ban on freight vehicles (i.e. trucks that weigh 3.5 tons or more) in a certain designated area, with camera recognition systems operating 24/7. Non-compliant vehicles face a penalty of €95 (US$112) plus a €9 (US$11) administration fee.
China: In July 2018, the city of Shenzhen implemented a similar ban on freight vehicles in an area of 22 square kilometers to improve local air quality. As opposed to camera surveillance, the scheme is enforced by the police. Non-compliant drivers are subjected to a fine of CNY 300 (US$45) and receive 3 points toward China’s 12-point system. If 12 points are accumulated, the license of the driver is suspended temporarily.
However, LEZs and CCZs have not always been a popular option. Earlier this year, the state of New Jersey sued the Biden administration in an attempt to block a plan to impose a daily congestion toll in New York City of up to US$23. The claim from New Jersey in the lawsuit was that the state would bear the brunt of a strain on infrastructure from drivers rerouting through New Jersey, as well as tens of thousands of New Jersey commuters who drive being limited in the modes of transport they could use to commute.
This argument raises questions about economic issues and imbalances that may still need to be addressed when implementing LEZs. The inequality between some areas may mean that some will not have the necessary infrastructure, such as buses, trains, or tram lines to be able to adapt to reduced car use. For many, driving is the only option in their region.?
Therefore, should these zones be implemented on a national and ultimately global level, government support will be crucial to ensure vulnerable citizens most affected are supported.
