Can the 1.5 deg C warming target be met in a global transition to 100% renewable energy?

TL;DR

This study suggests that meeting the 1.5°C warming limit is feasible with immediate global transition to 100% renewable energy and negative emissions, based on current technologies and remaining carbon budgets.

Contribution

It demonstrates that a rapid, large-scale shift to renewable energy combined with negative emissions can still achieve the 1.5°C target using current technology.

Findings

Feasibility of meeting 1.5°C with current wind/solar tech

Importance of immediate, large-scale renewable deployment

Role of negative emissions in staying within carbon budget

Abstract

Assuming the state-of-the-science estimates for the remaining carbon budget of carbon dioxide emissions, our modeling study supports the conclusion that it is still possible to meet the 1.5 deg C warming target even with current wind/solar energy technologies, if the creation of a global 100% renewable energy transition of sufficient capacity begins very soon, coupled with aggressive negative carbon emissions.
