Final answer:
Europe has combated transboundary pollution by enacting stricter regulations through the EU, limiting toxins in electronics and promoting proper recycling, and by participating in the Paris Agreement to support global efforts against climate change.
Step-by-step explanation:
One way that Europe has addressed the problem of transboundary pollution is by implementing stricter regulations through the European Union. These regulations are aimed at reducing pollutants, including the restriction of certain toxic substances in electronics and improving end-of-life recycling practices. Initiatives like these regulate the quantity of toxins that can be used and help manage their disposal, mitigating against further environmental damage. The European Union's actions serve as an example of regional cooperation to address pollution that affects multiple countries.
Furthermore, Europe is a party to the global framework for addressing climate change, notably the Paris Agreement, which aims to keep global temperature increases below critical thresholds. This agreement emphasizes international cooperation, including commitments by developed nations to support developing countries in their environmental efforts, recognizing the disparate effects of climate change across the globe.
