Collaborative research

Collaborative research constituted an important element of the Transitions to New Technologies (TNT) Program research portfolio in 2013, both within IIASA, with the Advanced Systems Analysis (ASA) and Energy (ENE) programs, and with outside partners, particularly in connection with the IPCC Fifth Assessment Report.



A major policy-relevant finding from TNT’s systemic approach to technology innovation is the need for policy integration, and its significant benefits, as shown from integrative work in a number of policy domains.   

An important paper resulting from TNT, ENE, and ASA collaborative research was published in the journal Climatic Change [1]. With its multicriteria optimization perspective, the paper develops an improved methodology to demonstrate the significant synergies and co-benefits from policy integration of minimizing air pollution impacts on human health and energy security, while addressing climate change concerns.

In 2013 TNT and ASA also jointly developed a research proposal which was accepted by the new IIASA Methodology Forum.  This new collaboration with ASA will draw on TNT’s previous agent-based modeling work by Tieju Ma, and is scheduled to begin in 2014.

Climate assessment reports

Activities in 2013 built toward completion of the IPCC Fifth Assessment Report (AR5) to which all senior Transitions to New Technologies (TNT) Program scientists are contributing. More

Technology-scaling methodology and modeling

In collaboration with the Energy (ENE) Program and the Potsdam Institute for Climate Impact research (PIK), Germany, the Transitions to New Technologies (TNT) Program applied its new technology scaling methodology to climate policy scenarios. More

New model developed to aid international climate cooperation

Transitions to New Technologies (TNT) Program developed a new regionally disaggregated model which will be a major policy basis for international climate cooperation. More
