Our COP26 mini-series focuses on key topics in the lead up to the UN's 2021 climate change conference. Many companies have pledged to reach net-zero greenhouse gas emissions by 2050 or earlier.

However, to achieve this will require the use of carbon offsets where they are unable to eliminate or reduce emissions in their own operations or supply chains. As the development of voluntary carbon markets, which is happening at a varying pace across the globe, becomes an important aspect in the "race to zero," our experts discuss what risks and opportunities this brings for the private sector.
