This preview outlines options to limit global temperature rise to 1.5°C and bring CO2 emissions closer to net zero by 2050. It offers insights on technology, investment and policies for a sustainable energy future.
G20 countries can work together to step up renewable energy development and drive an accelerated global energy transition.
Energy emissions from industry and transport could be cut to zero by 2060 with pro-active policies and investments. Renewables will be crucial.
This outlook highlights climate-safe investment options until 2050, policies for transition and specific regional challenges. It also explores options to eventually cut emissions to zero.
The brief, released at the global climate meeting COP25, underlines the opportunity to address the climate threat, decarbonise energy use and simultaneously achieve multiple Sustainable Development Goals.
The world needs USD 110 trillion worth of energy investments by 2050 for a climate-safe system. Currently planned fossil-fuel investments must be largely redirected into renewables, efficiency and other clean technologies.
Japan, holding the G20 presidency in 2019, asked the International Renewable Energy Agency (IRENA) for a report on the implications of the global energy transformation for climate and sustainability in a broad sense.
Increased use of renewable energy, combined with intensified electrification, could prove decisive for the world to meet key climate goals by 2050.
This working paper reviews approaches to sustainable intensification of pastureland that have had a neutral or positive effect on biodiversity of the affected areas and provides examples through case studies.
Active forest management has helped to boost bioenergy resources. Swedish experience offers valuable lessons for emerging markets.
