Despite vastly different populations and governing systems, the Eastern European nation of Romania and Asian behemoth China share something in common: Both have had a history of extensive industrial pollution. And, more recently, both countries have managed to grow their economies while substantially reducing carbon emissions.
According to new data from 2025, China’s “carbon intensity” (emissions divided by gross domestic product) has fallen by 12% over the past five years. However, the country remains the world’s biggest carbon emitter, with a nearly 33% share – and its emissions reduction rate lags far behind that of the West.
Romania, on the other hand, “has decoupled economic growth from pollution faster than anywhere else in Europe, and perhaps even the world,” The Guardian reported this week. Between 1990 and 2023, its carbon intensity fell by 88%, and current emissions are 0.2% of the world total. That’s a far cry from being one of Europe’s most polluted countries when it emerged from communist rule in 1989, and before Romania went on to build democratic institutions and transparent governance processes.
“Control of corruption, political stability, and regulatory quality reduced [Romania’s] pollution in the long-run,” concluded an extensive research study of the transformative years from 1996 to 2019. A second study from 2007 onward – when Romania joined the European Union, hewing to higher environmental standards – found that growing access to and use of renewable energy sources and technologies further reduced emissions.
In this respect, Romania’s trajectory mirrors that of other Western democracies – where private sector investment and market forces are balanced by government oversight and measures to protect citizen safety and environmental quality. Between 2000 and 2023, per capita GDP in the United States rose by 35%, while per capita carbon dioxide emissions declined by 29%. Over the same period, Germany, the United Kingdom, and France all recorded per capita GDP increases of around 20% and emissions declines of 30% to 40%.
Governing systems that enable innovation and investment have contributed to these gains, supporting what a Wall Street Journal article described as a shift from “climate catastrophism” to “a less strident but more sustainable climate realism, focused on innovation and the commercialization of low-carbon technologies.”
Many countries continue to invest in fossil fuels, even as they seek to improve efficiency, explore new technologies, and reduce negative environmental impacts. The data trends confirm that these aims are not mutually exclusive. A balanced approach can yield both economic and environmental dividends – for individual nations and the world.
