Options Winter 2021: In an attempt to reduce its carbon footprint, Japan has put ambitious strategies in place to reduce energy demand. IIASA researcher Shinichiro Fujimori and his colleagues used modeling to explore potential energy system changes and their cost implications.

Options Winter 2021: Human activity is the main cause of climate change. It is also people who endure the worst of its impacts. It is a matter of utmost urgency that people are part of the solution.

Options Winter 2021: Scenarios are essential for exploring climate change. These stories of future Earth help to reveal how we might prevent global tragedy.

Policy Brief #31, October 2021. A harmonized scenario framework can help to align national climate policies with global goals.

Policy Brief #30, October 2021. Overshooting global temperature goals is risky. New research from the ENGAGE project shows the long-term economic benefits of scenarios that avoid overshoot and points out the investments needed to make it happen.

Options Magazine, Summer 2021: Actions to curb global warming can have an added benefit-cutting air pollution and saving millions of lives. This bonus however only takes us part of the way to truly clean air. We need ambitious policies focused on pollution - and urgently.

Options Summer 2021: IIASA researchers and colleagues from several other institutions worked together under the auspices of the Green Climate Fund to help developing countries better understand issues around climate mitigation and adaptation, and build local capacity for targeted action to support vulnerable populations.

Impact Sheet #19, January 2021. IIASA research has guided the global policymaking community in their efforts to limit global temperature increase to this ambitious goal. When the world’s attention was focussed toward the 2°C target, the institute’s sophisticated analysis mapped credible pathways towards the 1.5°C goal

Options Winter 2020: Systems science is ideally positioned to address global impacts and harness opportunities brought about by the COVID-19 pandemic. IIASA is actively involved in addressing emerging issues and supporting policymakers on the road to a more sustainable post-COVID world.

Options Summer 2020: Our world is in the midst of an economic transformation as labor upheavals and climate change wreak havoc on present sustainability models. Could a focus on women’s empowerment help find a way out?

Options Summer 2020: Researchers from IIASA and Israel have customized the IIASA MESSAGE and GLOBIOM models to Israel’s unique context, to provide Israeli policymakers with useful options and analyses as they plan for the future.

Policy Brief #24, July 2019. Investment in low-carbon energy is making a difference. IIASA research now provides decision makers with valuable data on the capital required to ramp up renewables, boost energy efficiency, redirect energy portfolios, and fill investment gaps.

Policy Brief #23, June 2019. IIASA research has found explanations for variations in estimates of global greenhouse gas emissions by 2030. According to the researchers, actions set out in countries’ nationally determined contributions are described ambiguously, introducing uncertainty into the stocktaking process. This poses a danger that action plans will not be strengthened sufficiently to avoid dangerous levels of climate change.

Policy Brief #22, June 2019. A study of seventeen climate and energy policies offers design guidelines for more effective policymaking and implementation.

Policy Brief #21, December 2018. IIASA research shows substantial benefits of climate mitigation and achieving the 1.5°C target, as well as where action is most urgently required to reduce the vulnerability of the world’s poorest to unavoidable climate impacts.

Policy Brief #14, November 2016. Two temperatures feature prominently in the Paris Climate Agreement: 1.5°C and 2°C. New studies from IIASA reveal substantially different climate impacts under these two targets and provide a clearer understanding of the challenges and benefits of aiming low on global warming goals.

Impact Sheet #12, January 2015. IIASA plays a leading role in shaping the annual Emission Gap Reports, launched by the UN Environment Programme (UNEP) in 2010. These reports assess whether emissions pledges from countries during the international climate negotiations are on track to limit temperature increase to 2ºC or less this century. The reports appear each year to inform governments and the international policy community about the possible gap that needs to be closed in order or the world to follow a globally sustainable pathway toward wider objectives, such as the green economy.

Impact Sheet #6, November 2014. In 2007 the Intergovernmental Panel on Climate Change (IPCC) asked the scientific community to develop new scenarios for the Fifth Assessment Report. IIASA scientists contributed to developing two new sets of scenarios: the Representative Concentration Pathways (RCPs)—four pathways for emissions, concentrations, and radiative forcing; and the Shared Socioeconomic Pathways (SSPs)—five possible paths human societies could follow over the next century. The RCP and SSP databases are hosted by IIASA.

Impact Sheet #7, November 2014. MESSAGE is a IIASA modeling framework for medium- to long-term energy system planning, energy policy analysis, and scenario development. It provides a flexible framework for the comprehensive assessment of major energy challenges. It has been applied extensively to developing scenarios for large global research programs, such as the latest three assessment reports of the Intergovernmental Panel on Climate Change (IPCC) and the 2012 Global Energy Assessment.

Impact Sheet #8, November 2014. The Global Energy Assessment (GEA), coordinated by IIASA, provides the scientific basis for the 2012 global initiative, Sustainable Energy for All (SEforALL), launched by former UN Secretary-General Ban Ki-moon. In addition, IIASA/GEA scientists developed analytical tools and policy options for the Global Environment Facility (GEF), the largest public funder of projects to improve the global environment. GEA authors, many from IIASA, also provided substantive input to the 2014 Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report.
