Dear Francesca
From our point of view, accompanying clients in the construction of their ESG and climate alignment strategy, the best option is to compare several data providers as much as possible. In fact we see that a single provider can rarely ensure ideal data quality or coverage on all the thematics connected to the construction of a TCFD report.
For a thematic such as Climate Alignment, it is possible to use open source solutions such as Carbon Disclosure Project (CDP), Science Based Targets, PACTA, ACT,... Or data providers like Carbon 4 Finance, Trucost, ISS ESG Arabesque s-ray,...
Combining providers and public sources can have multiple advantages including the reduction of additional costs. Moreover public sources usually have great transparency on their methodology, enabling you to better understand the metrics you might be using. The main pain point of those sources is the coverage, hence the advice to complete with private providers.
If you want to have more precise feedback I can give you more examples/ feedbacks of support that we provide to European financial actors on the good use of ESG data for their reporting requirements (TCFD, Article 29 ECL in France, Climate policy etc..) with both a technical and expertise angle. And specifically when it comes to aggregating data from several sources, with our SaaS platform ESG Connect (https://www.weefin.co/feature-page) we try to be as flexible as possible to ensure maximum final data quality.
