The article specifically mentions competition from New Zealand lamb and talks about food miles. Food miles are not necessarily a good comparison for total carbon footprint. UK lamb production is very energy intensive. From the paper's abstract: This paper assesses, using the same methodology, whether this is the case by comparing NZ production shipped to the UK with a UK source. The study found that due to the different production systems even when shipping was accounted for NZ dairy products used half the energy of their UK counterpart and in the case of lamb a quarter of the energy. In the case of apples the NZ source was 10 per cent more energy efficient. In case of onions whilst NZ used slightly more energy in production the energy cost of shipping was less than the cost of storage in the UK making NZ onions more energy efficient overall. https://researcharchive.lincoln.ac.nz/bitstream/handle/10182/4317/food_miles.pdf https://researcharchive.lincoln.ac.nz/bitstream/handle/10182...
