India’s existing Calculator – known as the India Energy Security Scenarios (IESS) 2047 – is currently being updated to align more closely to India’s climate needs and ambitions. Owned by NITI Aayog, and delivered by the Indian Institute of Technology (IIT) Bombay, the updated Calculator will involve structural changes to shift the tool from a five-year to an annual model, complemented by a full refresh of available climate data. New carbon reduction technologies will also be included in the more user-friendly model. From a policy perspective, the projected reduction in greenhouse gas emissions outlined by the tool will help to re-align key policies and decisions and track the progress to achieve India’s Nationally Determined Contribution targets. The updated IESS tool will also be linked to the India Energy Dashboards, enabling ministries and state governments to rapidly access the most recent data needed to develop their respective climate policies. A further update to the IESS tool will incorporate current and planned government schemes, policies and targets to ensure robustness in long-term energy planning.


The aim of the Malaysia Climate Action Simulator (MCAS) is to support Malaysia’s low carbon transition across all sectors, including energy, industry, waste, agriculture, forestry and other land use, with the primary aim of decoupling emissions from these sectors to build a low carbon economy by 2050. The tool will bring together policy makers, industry leaders, experts and civil societies to discuss and engage on climate change and explore various pathways for Malaysia to develop into a low carbon nation. The MCAS will help to identify the physically and economically possible scenarios to reduce greenhouse gas emissions for the country by 2050. The best workable scenarios for Malaysia will feed into its five-year development plan.


The Philippines is currently finalising its Nationally Determined Contribution (NDC) to replace the Intended Nationally Determined Contribution (INDC) that was submitted to the United Nations Framework Convention on Climate Change (UNFCCC) in 2015. The 2050 Calculator tool will be helpful in developing its succeeding NDCs. With its own version of this transparent, interactive energy and emissions model, the Philippines Department of Energy aims to improve its long-term energy strategies, formulate consistent policies and identify appropriate sectoral programs and projects that will promote low carbon development starting from the planning process. It will be used as a tool to engage experts, policy makers, senior officials, politicians and the public on how greenhouse gas emissions could be reduced over time, and also on the benefits, costs and trade-offs of different scenarios/possible pathways. It will bring real scientific evidence into the debate around energy issues and, in turn, will inform decision making. The project will also improve the long-term modelling capability of the Philippines Department of Energy.
