The CTI 2050 Roadmap Tool project

This webtool is the outcome of a year-long effort of deep analytical work and active stakeholder engagement. It builds on the model developed as part of the Carbon Transparency Initiative (CTI) by the ClimateWorks Foundation and has been extended and upgraded for Europe with the support of the European Climate Foundation (ECF), in consultation with other experts in the field. This consultative process took place between September 2017 and September 2018, and was concluded over the summer of 2018 with the testing of the model by a range of experts who have developed their own low-carbon scenarios to explore and develop the policy options under consideration.

This project has developed and used a simulation model of European emissions and the mitigation options available now and in the future, analysing possible pathways to reach net-zero greenhouse gas (GHG) emissions. The emissions scope of the model encompasses all sectors of the economy (Power production, industry, buildings, transportation, and Agriculture, Forestry and Land-Use (AFOLU)), and all GHG emissions sources covered by national inventories, including international aviation, shipping, and Land Use, Land-Use Change and Forestry (LULUCF).

For each sector of the EU economy that emits GHGs, the GHG emissions drivers and means of reducing them – referred to as ‘levers’- are modelled. Rather than calculating optimal pathways, the model allows the user to choose the ambition level of each individual lever, from a reference level up to a maximum technical ambition, and thereby explore different scenarios or pathways by 2050.

One of the objectives of this work is to increase the analytical basis available to define the adequate political framework for the low-carbon transition, increasing model transparency, ease of use, the comparability of existing scenarios, and ultimately the access of policy makers to the most useful information for decision making. In this logic, we are making a version of the model directly based on the full simulation model accessible online. This allows for the pathways used in the analysis to be explored in much greater details, as well as to design and test additional pathways.

The conclusions from the project are based on three core scenarios and are detailed in the “Net-Zero by 2050: From Whether to How” report. Detailed presentations on sectoral assumptions can be found here.

Conditions for use of the CTI 2050 Roadmap Tool

The CTI 2050 Roadmap Tool is provided free of charge and neither Climact nor the European Climate Foundation seek any direct or indirect financial compensation for its use. Use of the Tool to generate a scenario does not imply endorsement of the scenario by either Climact or the European Climate Foundation. Scenarios produced using the tool may be published provided the following disclaimer is clearly displayed alongside the scenario:

“The creation of scenarios using the ClimateWorks/CTI 2050 Roadmap Tool, that has been developed by Climact sa/nv and the European Climate Foundation, does not imply endorsement of those scenarios by either Climact nor the ECF, nor endorsement of any conclusions based on those scenarios.”

Suggestions for improvements to improve the tool or its functionality may be addressed to vm@climact.com.
