The Government recently rejected proposals for a 'meat tax' proposed as a way of cutting carbon emissions. This was great news, as it could have harmed British farmers and the climate. A plant-based diet can be more harmful than a mixed diet if fruit and veg are imported and not grown domestically.

This tax would encourage purchase of locally produced, seasonally available food. This will help support British farmers (who produce, on average, 2.5 times less CO2 than the global average) and reduce fossil fuels used to import food. Burning fossil fuels releases CO2 into the atmosphere, but the CO2 emitted raising meat and dairy animals can form part of a carbon cycle. The grasslands they live on are carbon sinks, such that some livestock farms are close to achieving carbon neutrality.
