Years Active: 2009-2014


This project analysed the accelerated decarbonisation of the global E3 (energy-environment-economy) system from 2000 through to 2050, with a comprehensive investigation of the costs and benefits of the different decarbonisation options.

This involved the construction of the global TIAM-UCL model (built on the TIMES modelling platform, which is the successor to the MARKAL platform) with a dedicated UK region. Key research questions included the impact on the UK of global resource flows, international emissions trading, and global technology innovation.

Further Information

The TIAM-UCL global (16 region) energy systems model - with its dedicated UK region - is now fully calibrated and operational. Recent updates include biomass trading and modelling non-CO2 gases (CH4 and N2O).

The UK Department of Energy and Climate Change (DECC) use the model in assessing long-term carbon prices. TIAM-UCL has also been used to model global technology learning for hydrogen (H2) infrastructure under UKSHEC H2 project. UCL has also initiated an international collaboration of future development of TIAM, with modelling institutions in Germany, Italy, France and Finland.

A series of international conference presentations have been made on the new model and a range of journal papers on global CO2 emissions burden sharing, the role of demand change, and resource prices have been published.
