How to use the Independent
Science Based Taxonomy


Select the activity you are looking for using the search bar.

The criteria set in the EU Taxonomy have been assessed, classified and color-coded whereby

Red = unscientific criteria to avoid
Amber = mixed criteria needing improvements
Green = robust criteria

Where possible, in the case of Red and Amber criteria we suggest alternative science based criteria.


What are the substantial contribution criteria of the Taxonomy?

An economic activity can make a substantial contribution to one or more of the environmental objectives set out in the Taxonomy. This means that, based on the technical screening criteria, the economic activity either has a substantial positive impact or substantially reduces the negative impacts of the activity for the given environmental objective.


What ARE the DNSH
Criteria of the Taxonomy?

The “Do No Significant Harm” (DNSH) criteria refer to the principle that economic activities classified as environmentally sustainable should not cause significant harm to any of the environmental objectives outlined in the Taxonomy.



Activity 4.26 : Pre-commercial stages of advanced technologies to produce energy from nuclear processes with minimal waste from the fuel cycle

Activity 4.27 : Construction and safe operation of new nuclear power plants, for the generation of electricity or heat, including for hydrogen production, using best-available technologies

Activity 4.28 : Electricity generation from
nuclear energy in existing installations

Nuclear power: The EU Platform on Sustainable Finance has identified critical DNSH issues in the criteria published by the European Commission regarding activities 4.26, 4.27 and 4.28 on nuclear power. Activities 4.26, 4.27 and 4.28 cannot be considered taxonomy-aligned as they do not ensure no significant harm to all the taxonomy objectives. They are therefore considered environmentally unsustainable.



Gas-fired power: The EU Platform on Sustainable Finance has concluded that the criteria published by the European Commission regarding activities 4.29, 4.30 and 4.31 on gas-fired power/heat/cool/cogeneration do not constitute a substantial contribution to climate change mitigation and that in fact they propose a performance level that even under conservative assumptions, will continue to fail Do No Significant Harm to the climate change mitigation objective over the economic life of the activity. Activities 4.29, 4.30 and 4.31 are therefore considered as environmentally unsustainable.
