All the models showed that deploying measures such as a carbon tax raises the cost of food production. Policies such as a global carbon tax or emissions trading system, applied to all sectors of the economy, would result in up to 170 million people going hungry, according to Austrian research institute the International Institute for Applied Systems Analysis (IIASA). In research published in Nature Climate Change, the IIASA found the agriculture sector, which is one of the biggest contributors to climate change, needs to adopt smarter ways of working, rather than blanket policies. The study also shows that if countries were able to reduce their greenhouse gas emissions, they could feed more people.
