RIVM looked into ways being developed to reuse raw materials used in solar panels. The four ways described by RIVM in this report are more sustainable than how solar panels are currently recycled.

People who live in areas with poor air quality are more likely to become infected with SARS-CoV-2. Moreover, the symptoms of COVID-19 are more severe, leading to more hospitalisations and deaths. This is the outcome of a study conducted by RIVM, Utrecht University, Wageningen University & Research and the Netherlands Municipal Public Health Services and Medical Assistance in Accidents and Disasters.

The Dutch diet can be healthier and more environmentally sustainable without costing consumers more money. This holds for all socio-economic groups in the Netherlands. This concludes Reina Vellinga (RIVM) in her doctoral thesis. Even with minor adjustments, our diet becomes much healthier and with less impact on the environment.

The overall air quality in 2022 was slightly worse than in 2021. Weather conditions such as temperature and drought played an important role in this difference. This is according to the large-scale concentration maps published by RIVM each year.

In 2023, RIVM will take systematic measurements of ultrafine particles in the outside air for the first time. This is necessary because little is known at present about ultrafine particles and their potential health effects. Ultrafine particles must be measured with different equipment than that usually used for particulate matter.

In 2022, the European Commission introduced a proposal for stricter air quality standards. With existing policy measures, the air quality in most of the Netherlands will meet these requirements by 2030.

RIVM expects the air quality to be poor or very poor for a brief period over Easter, particularly in areas where Easter fires are lit. This is because the burning of wood leads to high local concentrations of particulate matter in the air. These high concentrations may cause health problems. People affected by these problems are advised to avoid strenuous physical activity.

Textiles are produced using chemicals. Although many hazardous chemicals may no longer be used in textile production, they may still be present in donations of old clothing. RIVM has conducted a study into the safety of recycled textiles.

In 2021, greenhouse gas emissions were 1.8% higher than the year before. This marked the first time emissions had gone up since 2016. In 2020, emissions declined by 8.8%. The 2021 increase is largely attributable to CO2 and to the cold winter.

In 2021, the Netherlands once again met the European limit values for nitrogen dioxide emitted at ground-level by road traffic. This was also the case for particulate matter along the roads, with the exception of a small stretch of road near Velsen.
