From the article:

>To meet the Paris Agreement goals, the world needs to reduce greenhouse gases by unprecedented levels over the next eight years.
Unconditional and conditional NDCs are estimated to reduce global emissions in 2030 by 5% and 10% respectively, compared with emissions based on policies currently in place. To get on a least-cost pathway to holding global warming to 1.5°C, emissions must fall by 45% over those envisaged under current policies by 2030. For the 2°C target, a 30% cut is needed.
Such massive cuts mean that we need a large-scale, rapid and systemic transformation. The report explores how to deliver part of this transformation in key sectors and systems.
