The Energy Commission of Nigeria (ECN), the Federal Ministry of Environment and the British Embassy Abuja have jointly launched an updated version of the Nigeria Energy Calculator 2050 (NECAL 2050), a bespoke energy and emissions model to assist Nigeria in achieving its climate goals.
The present version of the NECAL 2050 Calculator – a tool that allows users to trial different options for reducing emissions at a faster rate and to build a pathway that meets long-term emission targets to 2050 – is designed to help industries and the energy sector to set their greenhouse gas emission reduction targets, as well as to identify realistic solutions which support the implementation of Nigeria’s climate commitments, also known as Nationally Determined Contributions (NDCs).
The update – the first in Africa – was delivered under the UK Government’s international 2050 Calculator programme, which is funded by the UK’s International Climate Finance, and was led by global engineering, management and development consultancy Mott MacDonald, and a consortium which includes Imperial College, Climact and Ricardo.
Nigeria has submitted updated NDCs, which include new mandates for industries to reduce their greenhouse gas emissions. The new NECAL 2050 Calculator reflects the prevailing policies, ongoing efforts in energy supply and demand, and proposes reference scenarios on energy production and consumption and greenhouse gas emissions from 2015 to 2050. The new version includes updates to six sectors: Transport, buildings, industry, CO2 removal & gases, electricity and land, and bioenergy & waste.
British High Commissioner, Catriona Laing, said: “The launch of the Nigeria Energy Calculator 2050 further strengthens bilateral collaboration between the UK and Nigeria on the clean energy transition. Nigeria’s energy sector accounts for 60 percent of total greenhouse gas emissions and the sector is also key to the delivery of Nigeria’s many development priorities; it is therefore critical to understand the options that are available to reduce emissions while matching energy supply and demand.
I look forward to seeing the NECAL2050 tool supporting different sectors of government to design and deliver high-quality policies that enhance the conditions for strong governance, growth, job creation and poverty reduction.”
Dr Abdulwaheed Ahmed, Energy Policy Planning & Analysis, at ECN shared: “The Nigeria Energy Calculator 2050 is an interactive Energy Planning tool that enables high level policy makers to appreciate, at a glance, energy development pathways that are either climate-friendly or otherwise. The first Nigerian Calculator developed in 2015 was one of the tools used in the determination of Nigeria’s NDCs in its commitment to climate change mitigations under the Federal Ministry of Environment. The NECAL 2050 will support Nigeria’s reporting to the UNFCCC, the National Biennial Update Report, The National Inventory Report in addition to alignment with the NDCs and the Nigeria Energy Transitional Plan (ETP).”
Jessica Brislin-Higgs, senior climate and sustainability consultant for Mott MacDonald and programme country manager for Nigeria, noted: “Nigeria is a pioneer – it is the first African country to produce an updated Calculator model. We would like to acknowledge the expertise and diligence of the core technical team at the Energy Commission of Nigeria, with support from the Federal Ministry of Environment, who have worked tirelessly on this project. These efforts are highly appreciated and will go far towards changing the trajectory of sustainable development in Nigeria.”
The NECAL 2050 is an open-source, user-friendly model. Unlike other energy models, the tool can be used by governments, stakeholders, academia and the public alike, including schoolchildren, to inform debate about which policies will be most effective in tackling energy challenges and reducing emissions.

Paul Currie, Mott MacDonald’s energy leader for Asia Pacific, New Zealand and Australia, outlines four key shifts essential to achieving Australia’s clean energy goals.
Delivering decarbonisation fairer and faster was the theme of Carbon Crunch 2025 in London this autumn. Keynote speaker Nigel Topping, the new chair of the Climate Change Committee, along with other speakers at the event explored why fairer matters and how going faster is critical to competitiveness.
In 2023, Mott MacDonald’s report Zero Emissions English Airports: Target Further Analysis, produced for the Department for Transport, explored the commercial feasibility of decarbonising airport operations across England.
How Port of Dover is leading the way on the drive to net zero was presented at Carbon Crunch 2025 in London and the session explored why decarbonisation strategies must be translated into tangible activities.
Mott MacDonald’s energy sector leader for Asia, Philip Napier-Moore, explores the opportunities and challenges shaping ASEAN’s clean energy transition – and what must happen next.
Google’s ambitious climate strategy is one that focuses not only on reducing its own environmental impact but also on enabling others to meet their sustainability goals. Speaking at Carbon Crunch 2025 in London, Google director of sustainability for Europe, Middle East and Africa Adam Elman outlined how the tech giant views its role as extending beyond its own decarbonisation.
Government has set out a Clean Power 2030 plan to decarbonise the electricity sector. But there is more to reaching this target in a fast and fair way than just finance, technology and infrastructure, according to speakers at Carbon Crunch 2025 in London.
Australia’s water infrastructure, much of it built in the 1960s and 70s, is at a critical juncture. Built for a different climate and demographic reality, many systems are now operating beyond their intended design life.
Cities are emerging as critical players in delivering scalable decarbonisation solutions and their role was underlined by a keynote address from Labour Peer and former Bristol mayor Marvin Rees at Carbon Crunch 2025 in London.
Mott MacDonald’s recent webinar explored how NHS organisations can utilise the Climate Adaptation Framework to design, develop and implement best-practice plans.
The Bulan Solar PV and battery energy storage system (BESS) is a landmark cross-border renewable energy initiative, delivering clean electricity from Indonesia to Singapore. It’s set to become one of Southeast Asia’s most ambitious green energy ventures.
In a bold move to decarbonise its energy system, the Shire of Collie – long known as Western Australia’s “coal town” – is boosting its grid resilience and sparking regional growth with the Enpowered Collie solar and battery energy storage system (BESS).
The HyBont Green Hydrogen Project was one of the first onshore green hydrogen projects from the UK government’s Hydrogen Allocation Round One (HAR1) funding and is a potential model project for hydrogen production in the UK.
This is the story of how we partnered with South East Water to develop the decarbonisation roadmap, processes and internal capability that has put it ahead of future reporting obligations.
