Greenhouse gas monitoring and verification

Climate and air quality

In the Paris Agreement, 195 countries agreed to work against dangerous climate change. But accurately measuring greenhouse gases is still in its infancy. We’re working on national and European emission inventories and a greenhouse gas verification system to lay the foundation for measures to combat climate change.

Greenhouse gases

The concentration of greenhouse gases in the atmosphere determines global warming. Atmospheric monitoring therefore lets us keep track of developments. The greenhouse gases we measure are carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). We’ve been measuring the first two in the Netherlands since 1992. It’s important for cities and individual sectors to measure their own progress. We now monitor emissions based mainly on statistics. But in many places, these are unreliable, incomplete, or insufficiently detailed.

Measuring emissions

To support climate policy, we’re working on ways of documenting greenhouse gas emissions. We do this by means of emission inventories and measurements. We convert measurement and satellite data from concentrations into emissions and their various sources. There are high expectations for measuring emissions with the help of satellites, and we’re focusing strongly on that work. But we also measure emissions directly on the ground. For example, we measure methane associated with oil and gas extraction at home and abroad.

Ruisdael Observatory

The Ruisdael Observatory is a nationwide observatory for atmospheric measurements. We work with partners there to measure, model, and understand atmospheric processes. This includes quantifying local greenhouse gas budgets. At Ruisdael we coordinate the measurements around Rotterdam. We also perform mobile measurements of methane sources, for example.

In August and September 2022, for example, we teamed up with the observatory to carry out a major measuring campaign in Rotterdam. We used a variety of measuring instruments, such as bicycles, mobile measuring vehicles, satellite instruments, and even aircraft, to map out urban emissions in the Rotterdam region.

European verification system

TNO is collaborating with international partners on a European greenhouse gas verification system. We’re doing this work in the VERIFY, CHE, CoCO2, and ICOS-cities projects. At present, we’re mainly identifying gaps in the emissions inventories, so that we can improve them. Ultimately, we’ll use greenhouse gas verification during the five-yearly global stocktake of the Paris Agreement. Here, we look at the progress made in achieving the climate targets. This will provide more clarity on actual emission reductions and whether additional action is needed.

Support in making policy choices

Over time, information from measurements and verification systems will show where progress is being made. In which sectors, for example. On that basis, additional measures will be taken in the most effective places. Our projects and knowledge thus contribute significantly to making policy choices. One example is our research report on methane emissions (only in Dutch) from gas extraction, with answers to a parliamentary question.

Climate change makes carbon sinks more vulnerable

15 September 2022

In a new publication by ICOS, new data confirms that natural carbon sinks such as the ocean and forests are not stable.

How CCU can shape the carbon transition

25 April 2022

Carbon capture and utilisation, or CCU, is a technology that involves capturing CO2 emitted from (industrial) processes and using it to make new products. It therefore doesn’t only reduce CO2 emissions, it creates new market potential. Government and industry alike see the necessity of understanding which CCU value chains are future-proof and economically, environmentally and politically viable. The Province of Zuid-Holland wanted to know what role CCU has in the future for the province.

TNO developed Waste treatment Tool for plastics in rivers

27 October 2021
Rivers are polluted with plastic waste. The Ocean Cleanup is determined to remove these plastics from rivers. For the environment and for value creation, the river plastics should be properly treated. However, waste treatment, infrastructure and costs for plastics are globally diverse and complex. TNO has developed the Waste Treatment Tool to determine best treatment options from river plastic waste.
