Over the previous years, a rising consensus has acknowledged the necessity to assemble a ‘system [wherein] each monetary choice takes local weather change into consideration‘. Whereas such a system continues to be removed from actuality, market contributors already produce and demand an growing quantity of climate-related data. Equally, many authorities all over the world are contemplating obligatory climate-related reporting. These developments increase myriad unanswered questions. We concentrate on the next in a current working paper:
- How have voluntary, climate-related disclosures of UK monetary establishments modified over time?
- Can prudential regulators affect present climate-reporting ranges simply by saying a future shift to obligatory reporting?
This publish summarises the primary insights from this paper.
A novel information set on disclosures of monetary companies within the UK
So as to reply the above questions, we construct a novel information set of voluntary, firm-level climate-related disclosures which are according to the suggestions of the Process Pressure on Local weather-Associated Monetary Disclosures (TCFD). These suggestions, revealed in 2017, are organised into 4 themes, beneath that are 11 extra granular suggestions on the knowledge to be disclosed.
Our method consists of 4 consecutive steps summarised in Determine 1.
Determine 1: Machine studying pipeline
First, we manually gather company stories of the largest banks, constructing societies and insurance coverage corporations between 2016 and 2020 within the UK. Second, we extract the knowledge from every web page of the stories, figuring out potential climate-related pages utilizing pure language processing (NLP) strategies. Third, we scale back the dimensions of our truncated pattern by figuring out pages which are actually climate-related utilizing a machine studying classifier and a supervised studying method. Lastly, we prepare 11 impartial classifiers to determine the knowledge disclosed on every company report’s climate-related web page that’s intently according to every of the person TCFD suggestions.
Our machine-learning method permits us to measure the extent of voluntary disclosures in a number of methods. We are able to merely depend the variety of company report pages that comprise disclosed data according to the 11 TCFD suggestions. We are able to additionally assemble binary variables indicating if a UK monetary agency discloses particular climate-related data in a given yr. Lastly, we are able to additionally compute the common variety of disclosed suggestions inside every TCFD particular theme (ie governance, technique, danger administration in addition to metrics and targets), or depend the whole variety of suggestions that companies offered data on.
Consequently, our novel information set permits us to acquire an in depth image of the voluntary, climate-related disclosures within the UK, and its evolution over time.
Evolution and determinants of climate-related disclosures within the UK
Wanting on the evolution of climate-related disclosures by UK banking and insurance coverage corporations in our information set, we are able to see an encouraging development. Not solely have these sectors all elevated the common variety of climate-related pages of their company stories since 2016, however they’ve additionally revealed extra pages offering better data according to the suggestions issued by the TCFD.
Determine 2: Local weather-related pages and TCFD suggestions
Curiously, whereas extra monetary establishments within the UK disclose data according to the TCFD suggestions annually, Determine 3 reveals that almost all of those disclosures are executed on the group degree, reasonably than at a subsidiary degree. This discovering will be helpful for regulators when contemplating coverage for consolidated degree of disclosures.
Determine 3: TCFD suggestions disclosed
Throughout each banking and insurance coverage sectors, local weather reporting according to TCFD suggestions has been fairly comparable, as will be seen in Determine 4. Whereas in 2016, solely about 30% of establishments in every sector disclosed climate-related data, by 2020 the shares of reporting establishments reached over 70% (on the group degree) throughout the 4 TCFD themes.
Determine 4: TCFD disclosure themes on the group degree
We contemplate how totally different traits of monetary establishments are associated to disclosure ranges. We observe that institutional dimension (measured through complete belongings) appears to matter essentially the most. Determine 5 reveals the big optimistic correlation between institutional dimension and the variety of TCFD suggestions disclosed.

Background on UK regulatory coverage bulletins
A basic sample we observe within the figures above is that there’s a important enhance in climate-related data revealed after 2018. There are a number of potential explanations for this. A primary set of potential causes relate to ‘world‘ elements, whereas a second set relate to UK ‘inner‘ elements.
International elements behind this enhance in local weather reporting may come up each from unusually giant and devastating pure disasters (eg, the intense wildfires in Australia in 2019), and/or from strain by worldwide local weather teams (eg FridaysForFuture and Extinction Revolt).
Nonetheless, this enhance in local weather disclosures may be pushed by UK inner regulatory modifications mentioned and introduced between 2018 and 2020. Over this era, within the UK, the Prudential Regulation Authority (PRA) issued a set of bulletins and publications to encourage the administration of climate-related monetary dangers (Desk 1).
Desk 1: Local weather-related coverage publication by the PRA
For instance, in 2018 the PRA revealed a session paper (CP23/18) proposing that monetary establishments below its supervision develop and keep an applicable method to disclosing climate-related monetary dangers. In 2019, a supervisory assertion (SS3/19) talked about the TCFD framework for example for monetary establishments to contemplate when growing their method to local weather reporting. And in July 2020, the PRA issued a so-called ‘Pricey CEO letter‘ with the express function of managing expectations by saying a concrete timeline for monetary companies to include local weather reporting according to TCFD suggestions. Concretely, this letter made clear that ‘companies ought to have totally embedded their approaches to managing climate-related monetary dangers by the top of 2021’.
The position of coverage bulletins for local weather disclosures
We look at whether or not any of the aforementioned coverage publications affected monetary establishments’ climate-related disclosures. Our empirical technique permits us to analyse how establishments affected by the coverage bulletins change their climate-related disclosures relative to these in a roundabout way affected by the bulletins.
Particularly, we make use of a difference-in-differences method within the spirit of Bolton and Kacperczyk (2021). We assemble the therapy group because the subset of monetary establishments whose degree of disclosure was beneath the common degree of disclosure when the TCFD suggestions have been revealed in 2017. The instinct behind this method is as follows: establishments already disclosing ample local weather data by 2017 – ie our management group – wouldn’t have been affected by these coverage bulletins, as a result of that they had already determined to reveal previous to any of the coverage publications.
Our regression specification permits us to manage for the world elements talked about earlier than, as we embrace establishment and sector-time fastened results. Moreover, we additional management for different doable traits, akin to institutional dimension (complete belongings), profitability (ROE), and leverage. In different phrases, our empirical setting permits us to determine the contribution of the inner UK coverage bulletins on UK monetary establishments’ climate-related disclosures.
We discover proof of a statistically important impact on handled establishments’ choices to reveal climate-related data throughout all 4 TCFD advice themes, however solely after the 2020 Pricey CEO letter. Particularly, we discover that these establishments that beforehand disclosed much less catch up by way of their disclosures after the Pricey CEO letter (as will be seen in Determine 6 the place the three vertical strains signify publication dates of the three coverage communications we contemplate).

B. Pages with TCFD suggestions
These outcomes are sturdy to a battery of exams, reported intimately in our working paper, together with utilizing a unique regression method, group specs, and inclusion of possession as an extra management.
On this weblog publish, we’ve got studied the degrees of climate-related disclosures within the UK monetary sector and their evolution over time. We use NLP and machine-learning strategies to generate a novel information set that collates the reporting data instantly from company stories.
We discover an growing development in local weather disclosures throughout all TCFD themes, and throughout each banking and insurance coverage sectors. We additionally discover proof of a big impact of coverage bulletins on establishments’ choices to reveal climate-related data.
Our findings present some attention-grabbing insights for policymakers who’re contemplating obligatory climate-related disclosure. Our outcomes counsel that previous to regulatory interventions, solely a fraction of companies disclosed climate-related data according to TCFD, and these have been largely bigger establishments. This hole in voluntary disclosures creates a case for regulatory intervention to encourage smaller establishments to reveal too. Certainly, our outcomes counsel that regulators setting clear timelines for obligatory disclosures will help speed up the development, which ends up in convergence throughout establishments.
