Taking 32 European governments to court

Challenge – preventing human right violations through climate inaction

European Governments have not taken the climate action they have committed to when they signed the Paris Agreement. If they continue this way, it is very likely that we will face the outcomes of several climate catastrophes. This is a violation of our human rights.

To ensure governments respect their commitments, six young people from Portugal filed a case against 32 European governments to the European Court of Human Rights.

Solution – generating international support for litigation applicants

Greenhouse partnered with the young people and their lawyers to generate international support for the applicants. Our communications strategy included building clear messaging for each of the possible outcome of the cases, media engagement (setting up press conferences and interviews with the applicants and legal team), running their social media channels with compelling content to build momentum, and undertaking stakeholder engagement.

Results – securing news articles, managing press relations and highlighting story through social channels

We generated over 3,000 news articles including BBC News, BBC World Service, The Guardian, CNN, Deutsche Welle, NHK and more. We maintained a constant stream of communication through press conferences, media materials, prior briefings and managed a WhatsApp broadcast channel on the day of the hearing 130+ journalists to ensure the narrative was controlled. On social media, the hashtags we introduced, #Youth4ClimateJustice and #WeAreWatching, combined for a total of 754 posts over the three-week period.

Impact – helping create a new avenue for litigation through climate win

The court has found 2/3 of cases, including our case, inadmissible. However, they have ruled the KlimaSeniorinnen v Switzerland as a win for the applicants. No other case has been able to come so far before, therefore this was a win for all three cases. These cases have created a new avenue for climate litigation and has encouraged other cases to be submitted with national courts.
