For the first time since 1995, the beginning of the statistical time series, Portugal recorded three consecutive years in which economic growth matched with a reduction in greenhouse gas (GHG) emissions. This trend highlights a persistent decoupling between economic growth and emissions.

In 2023, Global Warming Potential (GWP) decreased 8.9% compared to the previous year, totalling 52.7 million tons of CO¿ equivalent—the lowest result in nearly three decades. This reduction occurred in a context of economic growth, with Gross Value Added (GVA) increasing 3.1% in volume.

The combination of the reduction in GWP emissions (-8.9%) and the increase in Gross Domestic Product (GDP) (+3.1%) led to an 11.7% drop in the carbon intensity of the national economy, reaching the lowest level recorded since 1995.
