Guinea establishes relative targets for reducing greenhouse gas emissions in 2030 compared to the reference trend scenario. The trend scenario (known as &quot;Business-as-usual&quot;) is built on the basis of the following assumptions, from the reference year 2020, continuing to grow emissions by 6% per year over the period 2020-2030. It was decided to base the reference situation for this 2021 NDC on data and projections from the 3rd IGES and NERF, making it possible to build more robust ambition scenarios. This new data available makes it possible to consolidate and strengthen the commitments made in 2015.
