The Paris Agreement acknowledged climate change as an urgent threat to the planet and human society. To fulfil the aim of
limiting global warming, public and private investments and especially long-term investments are supposed to shift towards
sustainable practices. Given the high investments required to pursue a sustainable financial system, it will be essential to
involve the financial sector, as well as its participants and authorities. This thesis discussed the role the European Central
Bank (ECB) could play in a transition towards a sustainable financial system. First, the framework conditions and the need
for a sustainable financial system were explained, in particular the recent developments like for instance the introduction of
the EU Taxonomy regulation, a classification system for sustainable activities which aims to provide clarity and limit the risk
of green washing. After that, it was outlined how climate-related risks can spread to the financial system and why central
banks are concerned of them. Three links for the relation between climate change and the financial system were identified –
physical risks, transition risks and liability risks. In particular, the impact of climate change on price stability, financial stability
and the portfolio management of central banks were examined. The objectives and the strategy of the ECB were described,
to establish a base for the subsequent analysis of their instruments. Furthermore, the European Green Deal, an answer of the
European Union to the challenges caused by climate change was presented.
