Scotland’s net zero ambitions are often discussed in terms of wind farms, electric cars and heat pumps, however one of the biggest problems is far more basic: food.
The uncomfortable reality is that Scotland is extremely unlikely to meet its legally binding climate targets without major changes to how food is produced, bought and wasted. The numbers simply do not add up otherwise.
The Scottish Government’s own Net Zero Nation campaign states that Scottish households throw away around 600,000 tonnes of food every year.[1] Food waste is responsible for emissions from farming, fertiliser production, transport, refrigeration, packaging, retail, cooking and landfill methane. The Scottish Government has also stated that food waste accounts for a significant proportion of Scotland’s carbon footprint.[2]
A 2024 review into Scotland’s food waste reduction plan concluded that reductions are not happening at the speed or scale required to meet existing targets. The same review also admitted that no country has demonstrated how to consistently reduce food waste on a sufficient scale.[6] That is a significant admission because it strongly suggests current policies are nowhere near enough to deliver the scale of behavioural change required.
Scotland has already abandoned one major climate target. In 2024, the Scottish Government dropped its legally binding target to cut emissions by 75% by 2030 after warnings from the UK Climate Change Committee that the country was off track.[4] This was widely reported by national media and climate bodies.[7] More recently, further analysis has warned Scotland could still miss its 2045 net zero target unless there are substantial increases in agricultural reform, peatland restoration and carbon removal technology.
Agriculture remains one of Scotland’s largest sources of emissions, producing around 7.5 million tonnes of greenhouse gases annually.[3] More than half of agricultural emissions come from methane produced by cattle digestion and livestock farming. Official Scottish Government data shows that agricultural emissions have fallen by only around 13% since 1990, while Scotland’s overall emissions have fallen by approximately 51% during the same period.[3] This highlights one of the core problems with the current net zero strategy: electricity generation has decarbonised relatively quickly through renewable energy, but agriculture has not.
The UK Climate Change Committee and Scottish Parliament committees have repeatedly warned that delivery is falling behind ambition and that climate targets are becoming increasingly difficult to achieve without major behavioural and structural changes.[5]
Scotland is also struggling with wider waste and recycling targets. The Scottish Government previously aimed to achieve a 70% recycling rate by 2025, yet household recycling rates remain significantly below that target. Landfill bans have been delayed multiple times, while concerns remain about insufficient waste infrastructure capacity and continued dependence on transporting waste elsewhere for processing.
The central issue is behavioural change. Scotland can build more renewable energy infrastructure and electrify transport, but net zero also requires significant reductions in food waste, changes in diet, lower overall consumption, reduced packaging waste and substantial reform of farming practices. Scotland’s own Net Zero Nation campaign openly acknowledges that food production and food waste are major contributors to climate change.[8]
Without those changes, achieving net zero is wishful thinking on a grand scale.
This is why many analysts increasingly view Scotland’s targets as aspirational rather than realistic under current policies. The contradiction at the centre of Scottish climate policy is that while Scotland presents itself internationally as a climate leader, many of the practical foundations required to achieve net zero are either behind schedule, politically difficult or currently failing to deliver the required level of change.
Last year UK was attributed as being responsible for 0.6% of globally emissions, and of the UK emissions Scotland is only responsible for 9%.
9% of the 0.6%.
9% of 0.6% is: 0.09×0.6%=0.054%
Yes!! Climate globally is definitely changing, however, unless we sort out food buying and waste there is no chance of achieving the targets. Especially given it’s emissions are global issue.
Even if we achieved the Scottish targets it would be swallowed up by bigger countries not doing anything and adding to the issue.
Scotland may originally have embarked on the path to Net Zero with genuine intentions and clear environmental ambitions. Yet over the years, the banner of Net Zero has increasingly been used to justify the widespread expansion of energy infrastructure across not only our beautiful Scottish Highland, but communities throughout the UK.
For many people, the driving force no longer appears to be environmental responsibility, but financial gain.
India said in 2024 it had plans to open 45 coal mines. Not sure how that has progressed but, point is we will be paying for everything the world isn’t doing as we continue with this quest for Net Zero!
As for those MPs and MSPs banging on about us being respected global leaders that other countries will follow….
They must be all on glue!!
