WHO tightens guidelines for air quality

WHO has recently released the new Air Quality Guidelines. New scientific evidence has led to lowering of the air quality guideline level for annual nitrogen dioxide (NO₂) by 75% to 10μg/m³. Levels of fine particulate matter (PM_2.5) have been halved to 5 μg/m³ and levels for particulate matter (PM₁₀) have been adjusted to 15 μg/m³. For the first time WHO includes a peak season level for ozone, which is set to 60 μg/m³. More than 15 years of research have been conducted since the old guidelines. Scientific knowledge has improved with more precise methods in measurements, modelling and exposure assessment methods.

Call to protect the cloud forests

Where the Andes meet the Amazon, you will find one of the earth’s richest and most important biomes. Its role has been overlooked in our efforts to mitigate climate change.

Editorial: GHG emissions must be halved by 2030

In August 2021, the Intergovernmental Panel on Climate Change (IPCC) – the UN body for climate science – adopted the first report of the IPCC 6th Assessment Cycle.

Symbolic CO2 threshold crossed

Concentrations of CO₂ are now 50% higher than at the start of the industrial revolution.

Energy targets need to be bolder

The European Commission’s proposal “Fit for 55” includes new targets for renewable energy and energy efficiency. They have to go further to be in line with the 1.5°C goal.

Emission limits still breached

While most EU member states met their binding national emission limits in 2019, significant further action is needed to achieve the reduction commitments set for the period 2020–29 and for 2030 onwards.

Material recovery opportunities from the clean energy sector

The exponential increase in renewable energy sources is vital, and it is important to enable the vast circularity potential of these technologies.

Toxic threat from wood burning

The burning of wood and coal for domestic heating is a major source of air pollutant emissions, contributing to more than half of primary PM_2.5 emissions in the EU. A new study compares the emissions from various types of heating options.

Norway’s future without oil

A rapid shut down of Norwegian gas and oil extraction is necessary to be in line with the Paris agreement. The loss of GDP may only be 1% in 2050 compared to business as usual.

Norway’s oil and gas market grows – NGOs call for phase-out

The major factor driving the market is the increasing development of new oilfields in the country over the forecast period 2021–2025.

Paying farmers for carbon

Although costs for monitoring, reporting and verification are high for many result-based schemes, the European Commission favours a wider implementation.

The rise of floating solar photovoltaic farms

Solar power is now the cheapest source of electricity in history. To continue its expansion many have looked to the benefits of floating solar farms.

New EU farm policy supports business as usual

In the coming years the European Union will continue to fund intensive farming practices with only marginal tightening of environmental requirements.

Towards climate-friendly food production

We need to reduce emissions of greenhouse gases and nitrogen from what we eat. Nordic farmers and food producers show how it can be done in practice.

Five Years Lost: how finance is blowing the Paris carbon budget.

No future for nuclear power

Nuclear power has tried to reinvent itself for two decades with the so-called Fourth Generation and Small Modular reactors. Both have failed.
