Global cleantech market size by country 2030

The global key clean energy technologies market size on the supply side could reach almost 790 billion U.S. dollars in 2030, if countries fully implement announced energy and climate pledges. This would be a significant increase from the previous estimate as of late 2022, which was just over 620 billion U.S. dollars. China would dominate the market, at some 500 billion U.S. dollars.

Supplementary notes

The Announced Pledges Scenario (APS) assumes that governments will meet, in full and on time, all the climate-related commitments they have announced, including longer-term net-zero emissions targets and Nationally Determined Contributions (NDCs), as well as commitments in related areas such as energy access. It does so irrespective of whether these commitments are underpinned by specific policies to secure their implementation. Pledges made in international for a and initiatives on the part of businesses and other non-governmental organizations are also taken into account wherever they add to the ambition of governments.

*As of late 2022 corresponds to the project pipeline assessed for ETP-2023, including project announcements through to the end of November 2022. “Domestic supply from announced projects". **As of end-Q1 2023” corresponds to projects announced through to the end of March 2023.

Key technologies include solar PV, wind, batteries, electrolyzers and heat pumps.

Market size is calculated based on the unit cost for each technology in the APS, excluding installation and construction costs. All market sizes and revenues are expressed in undiscounted 2021 U.S. dollars.
