J&E members handle cases and participate in legislative processes in their countries, also providing legal analyses and consulting their national government.  J&E lawyers use innovative legal methods and tools to convince decision-makers into initiating positive change.

J&E members analyze the implementation of EU law, illustrate on-the-ground practice via case studies and design policy recommendations.  J&E defends the rights of communities and nature in court and take legal action against the offending governments.

In partnership with other NGOs, J&E campaigns for a change in law and enforcement and works to improve its campaigning activities and engage people via media tools.
