Countries Need More New RE Power To Achieve Global Climate Targets: Study

A new analysis from Climate Analytics claimed that the world would need more new wind and solar power installations to limit global warming to 1.5°C. Climate Analytics is a global science and policy institute. The analysis said that the globe would need to add renewables up to five times faster by 2030 at a rate of 1.5 TW a year to achieve the target.  

It said global wind and solar capacity needed to increase to around 10 TW by the end of this decade, up from 2 TW in 2022. It is achievable if the recent acceleration in capacity additions is maintained. 

 “Everyone from the EU to the COP Presidency is calling for a global renewables target, but this must be based on the safest route to net zero. We’ve shown that if the world accelerates new wind and solar fivefold to at least 1.5 TW a year by 2030 while cutting fossil use by 40%, we won’t have to rely on potentially unsustainable amounts of carbon dioxide removal in the future,” says Claire Fyson, Head of Policy at Climate Analytics.

The study distills key milestones the international community needs to meet by 2030 to keep warming below 1.5°C, including rapidly scaling up renewables this decade to 70% of the global power mix, cutting greenhouse gas emissions by 8% a year to halve global emissions by 2030, and a 34% cut to global methane emissions over this critical decade for climate action. Methane emissions in the energy sector would need to fall even faster, by 66%. 

“Our method takes only the latest global pathways with the most up-to-date information on technologies and costs. We know wind and solar can scale quickly and undercut fossil fuels in price. Our analysis shows they can do much of the heavy lifting so urgently needed this decade, so let’s fast-track their rollout,” says Dr. Neil Grant, Energy, and Climate Analyst at Climate Analytics. 

Not all pathways in the IPCC AR6 database are fully compatible with the Paris Agreement. The study’s method focused on the latest 1.5-aligned pathways that integrate sustainability constraints, filtering out older analyses and those that rely too heavily on risky assumptions. As a result, the study found just 0.1% of global power would come from CCS by 2030.
