is a free, interactive and open-source energy model of the entire world to 2050. It allows users to explore what it takes to tackle climate change. The Global Calculator was simultaneously launched in London and Beijing in January 2015 and continues to be a useful guide to explore global mitigation pathways and associated costs.

Why use it?

To explore what it takes to tackle climate change on a global level and to learn what mitigation options make a real difference and impact on lifestyles:

• Learn about energy, land, food and climate issues – how they are related and how they interact
• Understand how sectors will evolve at a global level to lower carbon by 2050 and see which markets could grow in the future
• Help inform internal strategies and campaigns
• Determine whether country plans are aligned with a global 2°C pathway
• Discover what technologies and actions we need in future.

How can I access it?

 - tutorials, videos and user guides‌ will be made available on this site.

A revamped India Energy Security Scenarios () tool was launched in July 2023. Housed by the Government of India’s Planning Commission, , and developed with the Indian Institute of Technology Bombay (), the updated IESS 2047 is the culmination of over two years of work and is the third update to the Calculator. IESS 2047 is expected to be used by government, private sector, academic, and NGO stakeholders.

The  is helping Kenya to meet its target of becoming a net-zero economy by 2050. Housed within the  and developed by , KCERT is supporting the development of long-term strategy for Kenya’s climate change mitigation measures. KCERT is a useful tool for providing data and guiding implementation as Kenya implements its Energy Act 2019 and develops other sectoral plans and strategies, such as long- and medium-term plans.

KCERT was designed to meet the requirements of the Constitution of Kenya 2010 in terms of public participation in policy development, facilitating engagement of government, industry, academia, and the general public on sustainable energy planning. The tool makes it simpler to easily access real data to support better decision-making. KCERT also assists in planning and organising existing climate change mitigation activities undertaken by the Ministry of Energy as well as other mitigation projects being undertaken in various sectors in Kenya. The tool presents Kenya with a unique opportunity to provide leadership in the East African region on climate change mitigation in the sustainable production and use of energy. 

Demonstrating the country’s commitment to decarbonisation, was developed and released by Strathmore University. The tool builds on the data housed in KCERT 2050, presented in an accessible and engaging format for use by the general public. Aimed at students and policymakers alike, My2050 Kenya makes it possible for all Kenyans to explore and share their vision for a low carbon economy.

The aim of the Malaysia Climate Action Simulator () 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 brings 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 helps to identify the physically and economically possible scenarios to reduce greenhouse gas emissions for the country by 2050.

The  aims is to identify energy secure pathways in the country for energy demand and supply between 2020 and 2060. The Calculator, developed by the Energy Commission of Nigeria (ECN) and the Federal Ministry of Environment, helps users (government, businesses, scholars, and individuals) to understand the wide range of possible energy pathways available to the country as it develops its energy sector. It provides quantities of energy demand, supply, emissions, and potential implications on issues such as import dependence, cost, and land requirements, and it offers a platform to facilitate policy debate about the possible future pathways for the Nigerian energy sector, while enabling prioritisation of potential policy interventions for deeper analysis

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.

The Thailand 2050 Calculator is helping the country consider the appropriate low emission pathways to achieve its nationally determined contribution (NDC) target by 2030, in particular, to implement its national long-term strategy for low carbon development towards 2050. Hosted within the , the Thailand 2050 Calculator is being used as an integrated tool to revise Thailand’s energy blueprint which consists of power development, energy efficiency, alternative energy development, gas, and oil plans. This will give EPPO and the Thai Government a clear picture of the impact of each activity or aspect, and ultimately propel a gradual transition to a low carbon economy in Thailand by 2050. In addition, the Calculator is expected to be used to raise public awareness of the greenhouse gas emission situation and climate change issues through the model’s launch events, and related teaching courses/modules to encourage research using the tool.

Vietnam's original 2050 Calculator model was built in 2014 and upgraded in 2015/2016 with the support from the UK Department of Energy and Climate Change (DECC) and the British Embassy in Hanoi.

The  has now been updated again to include recent data and to expand industry and supply sectors to provide a deeper level of understanding of how these sectors impact national greenhouse gas emissions.

The main aim of the upgrade is to support the  to implement Vietnam’s nationally determined contribution (NDC). Specific objectives are to assess the new NDC target, support MOIT to prepare and implement an action plan to implement NDC goals in the energy sector, and monitor and measure the implementation of greenhouse gas emission reduction in key energy sectors and sub-sectors.
