sabine mauderer : sustainable finance and the availability of good quality data welcome remarks by dr sabine mauderer, member of the executive board of the deutsche bundesbank, at the international conference on statistics for sustainable finance, jointly organised by the bank of france, deutsche bundesbank and the irving fisher committee on central bank statistics, paris, 14 september 2021. * * * 1 introduction good morning ladies and gentlemen, colleagues and friends, i am delighted to be here today. it gives me the opportunity to talk about two subjects close to my heart : sustainable finance and the availability of good quality data. many of us laughed when – almost ten years ago – the harvard business review proclaimed that ‘ data scientist ’ would be the sexiest job of the 21st century. but as we all know, statistics and data have been growing in importance all the time, propelled by fascinating technological changes. enhancements made possible by state - of - the - art statistics and data analytics have become critical factors for success – for businesses and public sector institutions. also for central banks. timely and consistent data are essential for our analyses of trends and shifting patterns in financial markets and the economy at large. i am not exaggerating when i say that the availability of rich and up - to - date data is key to good policymaking. in a similar vein, the market for sustainable finance has grown in leaps and bounds, and the topic is now shifting into the mainstream. who would have thought, just a few years ago, that central banks would include climate change considerations in their monetary policy strategies? many central banks, including the eurosystem, are addressing climate - related risks on their balance sheets and in their roles as supervisors. it will therefore come as no surprise to you that the eurosystem is bundling its efforts to make more climate - related data available for research and analyses, besides developing new collections of statistical data. 2 specific examples as part of my work in the network for greening the financial system, the ngfs, we are pushing hard to improve the global data situation. we recently published a “ dashboard on scaling up green finance ”. this contains a set of 21 indicators, which allows the various stakeholders to track and evaluate progress in greening the financial system. if you are interested in green finance in germany, the bundesbank ’ s own dashboard for green finance indicators can be a treasure trove, and it is easy to find on our website1. 1 / 3 bis central bankers '

speeches nevertheless, the need to strengthen the climate information architecture remains acute. the ngfs ’ s progress report on bridging data gaps, which came out this may, offers an excellent stocktake of the current data situation and identifies ways to bridge prevalent data gaps2. 3 challenges and opportunities so what are the challenges – or rather, the opportunities – in data collection and processing? good quality datasets are essential for any decision maker. governments need them to decide on the future path of carbon taxes or to benchmark carbonemission reductions. investors need detailed information on the climate footprint of companies, to weigh their investment decisions. nevertheless, many data collections remain fragmented, characterised by modest quality, insufficient coverage and low granularity. scattered data sources and cumbersome access further complicate the situation. at the same time, it can make sense to draw on multiple data sources. looking at various data pools helps to reveal measurement uncertainties and differences in the coverage of third - party data providers. therefore, it is essential to improve the coverage and consistency of data collections. or to put it boldly : we need to build a sustainable finance data universe. this, however, as governeur francois villeroy de galhau rightly observes, will only be achievable through better and more consistent disclosure and reporting. thanks to digitalisation, we have deeper and faster technologies at our disposal. the same technologies that led to the emergence of a fintech sector after the 2008 financial crisis can make it possible to gather and process sustainability - related information. but it is not enough to establish a data universe. to unlock its potential, stakeholders need easy access. in that respect, the green finance dashboards i mentioned just now can serve as door openers to existing data sources. also, the oecd is a pioneer in making good quality sustainability data easily accessible to everyone. it maintains a range of granular datasets on environment, biodiversity, green growth, climate and ecological items – freely available on the oecd ’ s website. ladies and gentlemen, the need to build a truly international hub is more pressing than ever. that is why i would like to draw your attention to a great initiative by our ngfs colleagues. 2 / 3 bis central bankers'speeches they are working on a repository of data sources and data needs that they aim to broaden and deepen over time – following the vision of a sustainable finance data universe. 4 conference programme looking at the various tasks
