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.

Sustainable bioenergy could even out solar and wind variability and replace fossil fuels for industry, transport and buildings.

This report outlines a pathway for the world to achieve the Paris Agreement goals and halt the pace of climate change by transforming the global energy landscape.

G20 countries can work together to step up renewable energy development and drive an accelerated global energy transition.

本レポートでは2050 年までの気候変動に配慮した投資、エネルギー移行に必要な政策の枠組み、及び各地域が直面する課題に焦点を当てている。また、最終的に排出量をゼロにするための選択肢も探っています。

Doubling renewables in the global energy mix by 2030 is not only feasible, but cheaper than not doing so. This second edition of IRENA’s global roadmap provides an in-depth perspective on the energy transition in 40 economies, representing 80% of global energy use. It offers concrete technology options and outlines solutions to accelerate renewable energy growth.

This brief quantifies air pollution and climate change externalities related to fossil fuels, along with the extent these can be reduced with higher uptake of renewables.

This set of briefs, prepared by the International Renewable Energy Agency (IRENA), highlights challenges and opportunities as the world seeks climate-safe energy solutions.

Energy transition investments in the wake of COVID-19 can pave the way for equitable, inclusive and resilient economies.

REmap 2030 provides a plan to double the share of renewable energy in the world’s energy mix between 2010 and 2030. It determines the realistic potential for the world to scale up renewables in order to ensure a sustainable energy future.

Technological breakthroughs are needed to reduce carbon emissions in the energy sector. This working paper examines the basic conditions required to nurture innovation and produce new technologies for a low-carbon future.

This joint study looks at the potential for decarbonisation in the energy sector in G20 countries and around the world. Chapter 3, “Global Energy Transition Prospects and the Role of Renewables”, highlights findings from the International Renewable Energy Agency (IRENA).

REmap 2030 is a roadmap to double the share of renewable energy by 2030. It is the first global study to provide renewable energy options based on a bottom-up analysis of official national sources. The roadmap encompasses 26 countries representing three-quarters of current energy demand. In determining the potential to scale up renewables, the study not only focuses on technologies, but also on the availability of financing, political will, skills, and the role of planning.

Assets like power plants can become “stranded” by unanticipated or premature write-downs, devaluation or conversion to liabilities. This will happen to some degree in the transition to a low-carbon economy. However delaying action to address climate change would result in significantly more severe asset stranding, according to this analysis by the International Renewable Energy Agency (IRENA). This raises concerns for investors and companies, as well as policy makers and regulators. 

Renewable energy needs to be scaled up at least six times faster for the world to start meeting key decarbonisation and climate mitigation goals. Yet the envisaged energy transformation cannot happen by itself. This report identifies focus areas where policy and decision makers need to act.

This brief provides a high-level overview of priorities to accelerate technological and systemic innovation and highlights priorities for increased government action and international co-operation.  

This study presents options to fully unlock the world’s vast solar PV potential over the period until 2050. It builds on IRENA’s global roadmap to scale up renewables and meet climate goals.

This report guides policy makers to stay on the the 1.5°C path to 2050, explores the socio-economic impacts of the transition and suggests ways to speed progress towards universal access to clean energy.

While the shift to cleaner energy systems is evident across the Group of 20 (G20), it has specific features in each country. In every case, renewable energy plays a significant role.

This study presents options to speed up the deployment of wind power, both onshore and offshore, until 2050. It builds on IRENA’s global roadmap to scale up renewables and meet climate goals.

Increased use of renewable energy, combined with intensified electrification, could prove decisive for the world to meet key climate goals by 2050.

This report explores two broad future paths: Current Plans (meaning the course set by current and planned policies) and the path for a clean, climate-resilient Energy Transformation.

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.

In October 2015, the G20 adopted the “Toolkit of Voluntary Options for Renewable Energy Deployment”. This report summarises the results for the G20, identifies action areas for G20 policy makers and proposes the next steps of a “REmap G20 process”.
