Association for the

Catalytic Control of Emissions From

Stationary Sources to Air

Improving the air we breathe by using advanced technology to control emissions from power stations and industry

We work globally with regulators, NGOs and others to advocate the development, demonstration and deployment of

cost-effective emissions solutions.

Our goal is for the same level of awareness and implementation of catalytic controls for industry as there currently are for transport.

What We Do

Promoting the technical and economic viability of catalytic controls to reduce harmful discharges to the air from large fixed (stationary) industrial sources such as factories and power stations.

We are a non-profit trade group based in Brussels and administered by leaders in the field of emissions control: Clariant, Gore, Johnson Matthey, Umicore.

Stationary sources now account for 58% of global greenhouse gases... more

How Catalytic Converters Work


Catalytic after-treatment works in a similar way to catalytic converters in cars, but on an industrial scale.

Channeling gases emitted by industry through this process means pollutants can be neutralised by more than 95%. Thus rendering them virtually harmless when released into the atmosphere... more

Industries & Sectors We Work With


The main stationary sources of emissions  are:

- Energy Generation

- Waste Incineration &                  Biomass

- Mineral Processing

- Metals & Foundries

- Industrial Manufacturing

- Food & Drink Processing

- Wood Pulp and Paper

Each process gives off different poisonous emissions requiring the kind of treatments our partner companies install... more

Why is our work necessary?

polluting chimneys with smoke

While the problems of emissions from vehicles are widely known there are many other dangerous chemical emissions from large stationary sources including: Nitrogen Oxides, Carbon Monoxide, Methane, Ammonia, and Mercury. Industrial facilities - and the exhaust gases they release - are much less controlled by government mandates yet are just as harmful as those emitted by transportation. 

Their effect on the environment damages human health from polluted air and contributes to climate change. Non-CO2 emissions represent over 25% of total pollutants, predicted to rise to 27% by 20301 ... more
