Investing for the long term: quantifying the economic costs of an accelerated energy transition in Oil & Companies News 25/04/2026 The economic effects of the energy transition are multifaceted, ranging from mitigation and adaptation costs, including clean energy investment, in the short term to the benefits of avoided climate damage down the line. In many economies, cost-of-living pressures and strained public finances are being increasingly conflated with decarbonisation costs. Consequently, the question of whether the energy transition will actually boost economic growth has become more critical for governments, companies and households. In a recent report, our economists explored what the energy transition is likely to mean for GDP growth out to 2100 at both global and national level under Wood Mackenzie’s ‘net zero’ and ‘country pledges’ Energy Transition Scenarios.

Short-term costs of decarbonisation vs long-term economic gains from climate action Understanding the full economic story of the energy transition requires taking a view to the end of the century. We find that, over the very long term, the economic benefits of avoided climate damages outweigh the costs of cutting carbon emissions in the immediate future. The global economy will take an initial hit from a more rapid energy transition. In 2050, under our country pledges scenario (a 2°C rise in global temperatures compared with pre-industrialisation levels), GDP shrinks 1.1% relative to our base case (a 2.5 °C rise in global temperatures), while under our net zero scenario (a 1.5°C pathway), it declines by 1.6%. By 2070, however, cumulative GDP growth turns net positive against our base case under both accelerated energy transition scenarios. By 2100, annual GDP is projected to be 32% higher under our net zero scenario and 21% higher under the country pledges scenario than in our base case. The global economy will grow at a compound annual growth rate (CAGR) of 2.2% between 2025 and 2100 under the net zero scenario and 2.1% under the country pledges scenario, compared with 1.9% in our base case. Why equitable energy transition policies are critical for economic growth and cost management It is crucial that short-term policy decisions balance the immediate cost pressures of decarbonisation with these long-term economic gains to avoid undermining transition progress. Governments need to weigh the energy security benefits of a faster energy transition against the economic costs of achieving it, and energy supply disruptions caused by the conflict in the Middle East should sharpen focus on this. Furthermore, financing should be optimised to ensure global equity and intergenerational fairness. The energy transition presents a significant growth opportunity for companies. The path to higher economic output relies on technological innovation and the deployment of low-carbon solutions. Between 2025 and 2050, US$117 trillion in energy-related investment is required to achieve net zero. Most of this investment will go towards electrification and renewables. Companies will look to governments to remove the regulatory barriers currently impeding the development and upscaling of these technologies to unlock this economic potential. The upfront transition costs may add to near-
