Greenhouse gas emissions from Europe’s energy-intensive industries have dropped significantly over the past 20 years, yet the pace of progress is losing steam.

A new briefing from the European Environment Agency (EEA) warns that without more ambitious structural changes and full enforcement of existing EU rules, further gains could prove difficult.

The report examines how heavy industrial sectors have evolved in terms of greenhouse gas and air pollutant emissions. It also looks ahead, mapping out realistic pathways to accelerate decarbonisation while strengthening Europe’s industrial base.

A two-decade decline in emissions

Since the early 2000s, emissions from Europe’s most energy-hungry manufacturing sectors have fallen sharply.

Greenhouse gas emissions are down by roughly 42%. Air pollutants have also declined considerably, including nitrogen oxides (NOx), sulphur oxides (SOx), dioxins, and heavy metals such as nickel.

These reductions span industries that form the backbone of European manufacturing: iron and steel, cement and lime, aluminium, pulp and paper, glass and ceramics, and chemicals.

Together, these sectors account for more than a quarter of total EU industrial greenhouse gas emissions and over 60% of manufacturing energy consumption.

Importantly, the economic output of these industries, measured in gross value added (GVA), remained broadly steady during much of this period.

That suggests earlier emissions cuts were largely achieved through cleaner technologies, tighter standards, and improved efficiency rather than economic contraction.

Post-2020 shifts raise questions

However, the more dramatic emissions reductions seen after 2020 tell a more complex story. The EEA notes that these sharper declines coincided with a decline in industrial output.

This points to structural economic changes playing a larger role. Reduced production, energy price shocks, and weaker demand – especially in sectors like steel, which face global overcapacity – have all contributed.

In other words, part of the recent emissions drop may reflect slower industrial activity rather than lasting transformation.

That distinction matters. If emissions fall mainly because factories produce less, reductions may not hold once demand rebounds.

High energy costs add pressure

Europe’s energy crisis has intensified challenges for energy-intensive industries.

These sectors depend heavily on electricity and fuel, and European electricity prices remain significantly higher than those of major trading partners – often two to four times more expensive. That gap has weighed on competitiveness. Companies already navigating global competition, volatile demand, and pressure to decarbonise now face structurally higher operating costs.

For policymakers, the balancing act is clear: drive down emissions without driving industry away.

The hidden cost of pollution

Despite the progress made, pollution from energy-intensive industries still comes at a hefty price. The EEA estimates that the health and environmental damage linked to air pollution from these sectors costs society around €73bn annually.

These so-called external costs include respiratory and cardiovascular diseases, environmental degradation, and premature deaths. Cutting pollution further would not only reduce emissions but also deliver tangible public health benefits and ease pressure on healthcare systems.

Lower societal costs could also strengthen Europe’s long-term economic resilience.

What needs to happen next

The report argues that incremental improvements will not be enough. Achieving deeper emissions reductions will require full implementation of existing EU climate and environmental legislation, alongside more fundamental changes in how materials are produced.

This transformation sits within the broader context of the European Union Clean Industrial Deal, which aims to combine industrial competitiveness with climate neutrality.

Key pathways identified include electrifying industrial processes, switching to alternative feedstocks, increasing the use of secondary raw materials, and embedding circular economy principles.

These approaches can simultaneously reduce greenhouse gases, cut air pollution, and lower resource dependence.

However, the briefing cautions that not all solutions are universally beneficial. Some technologies may reduce carbon emissions while increasing other environmental pressures, or vice versa.

That means policies must be tailored sector by sector, taking into account trade-offs among climate, air quality, and resource-efficiency goals.

Smarter policy and investment decisions

An integrated perspective will be essential when designing funding mechanisms, updating permitting frameworks, and setting sustainability standards. Public procurement policies, for example, could play a stronger role in supporting low-emission products such as green steel.

For Europe’s energy-intensive industries, the message is clear. The past two decades show that emissions can be reduced without hollowing out economic value. But the easier gains have largely been made.

From here, real progress will depend on accelerating technological change, aligning policy tools, and ensuring that decarbonisation strengthens, rather than undermines, Europe’s industrial future.
