A quarter of the greenhouse-gas emissions that cause climate change come from food. In Food and Climate Changewithout the hot air, Sarah Bridle details the carbon footprint of the food we eat, from breakfast to lunch, from snacks to supper. She breaks down the environmental impact of each food, so we can see where the emissions are highest and where we can make sustainable food choices.
With this knowledge, we can make changes to our diet – e.g. eating more locally grown produce and introducing meat free days. This will reduce the greenhouse gas emissions so damaging to our planet and probably be healthier for us, too.
Food and Climate Changewithout the hot air considers:
How to reduce the greenhouse gas emissions that come from food – currently 25%.
What effect the food we eat has on the environment of our planet.
How climate change will affect the food we will eat in the future.
How consumers can play their part in reducing food-based carbon emissions.
Bridle looks at popular breakfast, lunch, snack and dinner options, such as tea and coffee, eggs, cheese and chicken sandwiches, salad, pizza, baked potatoes, chocolate, nuts, soft drinks, alcoholic beverages, steak and fries, fish suppers, Spaghetti Bolognese and more.
She calculates the greenhouse gas emissions of those meals, breaking down the different ingredients and cooking methods, which makes it easy to compare different options within the same meal. This takes into account all the gases that contribute to global warming: carbon dioxide, methane and nitrous oxide (gCO2e). Bridle also dives into the important topic of food waste and gives valuable tips to avoid leftovers.
Inspired by the author's former mentor David MacKay (Sustainable Energy without the hot air), Food and Climate Change is a rigorously researched discussion of how food and climate change are intimately connected. In this ground-breaking and accessible work, Prof Sarah Bridle focuses on the facts so that they speak for themselves. The book is highly illustrated in full colour throughout, making it an attractive read, as well as an inspiring one.
It shows how anyone can reduce the climate impact of their food. It also suggests how the food system must change, with:
Incentives for farmers to switch to more efficient, climate-friendly technologies.
Food labelling to show a product’s ‘food miles’ and how it has been produced.
Research into non-traditional production methods.
How to waste less food and use all the water, energy and nutrients used in its production more wisely and sustainably.

Did you know a latte is ten times worse for the climate than a cup of black coffee? Or that each calorie of beef requires 20 calories of feed? ‘Food and Climate Change Without the Hot Air’ provides a levelheaded, clear, and detailed picture of food emissions - a basic literacy we should all have in a time of accelerating climate consequence.
- Peter Kalmus, NASA climate scientist and author of 'Being the Change: Live Well and Spark a Climate Revolution'
This is a wonderful, fact-filled but readable book, full of clear explanations of the emissions associated with everything we eat, identifying what is important and what is negligible. I shall never look at spaghetti bolognese in the same way again.
- Prof Sir David Spiegelhalter, Winton Professor of the Public Understanding of Risk at Faculty of Mathematics, University of Cambridge
I’m rather glad, perhaps, that I hadn’t read Sarah Bridle’s book before dinner. It allows readers no refuge from the inescapable climatic consequences of their dietary desires because it quantifies them in such orderly and precise terms. It’s a marvel of synthesised research, clear explanation, and friendly wit.
- Prof Philip Tabor, Former Director of the Bartlett School of Architecture, University College London
Sarah Bridle leads the reader through the climate impacts of our food, meal by meal. She uses the most up-to-date science and brings it to life in a personal, engaging and non-judgemental way.
- Prof Pete Smith, Director of the Scottish Climate Change Centre of Expertise
Sarah Bridle has turned a page in our understanding of the impacts of our everyday eating habits with this ground-breaking, well-researched and accessible book. It will enable conscious decisions by individuals and industry concerned over the sustainability of our planet.
