This weekend hundreds of thousands of people marched in cities across the world to show world leaders that serious action needs to be taken to combat climate change. This is required not only to preserve the environment, but also because of the impact of climate change on the most poor and marginalised people. A recent ODI report shows that over 700 million people are set to re-enter extreme poverty between 2030 and 2050 if business as usual continues. The figure below shows this will be caused due to drought, reduced agricultural productivity, increased food prices and malnutrition.
The report also shows that many of the actions required to combat climate change are actually ‘growth enhancing’. In other words, they are likely to boost GDP growth. For example, increasing energy efficiency is set to not only help combat climate change, but also reduce losses to the economy.
