On 31st January 2022, the Climate Disclosure Standards Board (CDSB) was consolidated into the IFRS Foundation to support the work of the newly established International Sustainability Standards Board (ISSB). While this site and its resources remain relevant for preparers looking to improve sustainability disclosure until such time as the ISSB issues its IFRS Sustainability Disclosure Standards on such topics, no further work or guidance will be produced or published by CDSB. For further information please visit the IFRS website.


Building the TCFD Knowledge Hub

Creating the TCFD Knowledge Hub has been one of my greatest achievements and, hopefully, a legacy that will continue long after I have left CDSB. The idea for the Hub came in 2017 from our Managing Director, who came back from an external meeting and announced to the team that we should create an online platform to support the implementation of the TCFD. We planned for a central repository to bring some order to the overwhelming amount of guidance, research and resources that were starting to be published in the wake of the TCFD recommendations.

CDSB’s hidden hero: Michael Zimonyi

Often when people talk about CDSB they talk about the leaders. For most of the organisation’s existence, CDSB has been a small Secretariat under 5 people. Lois Guthrie, CDSB’s Founding Director and I often said we ran the company on fairy dust, a little magic and a lot of coffee.

In this article Founding Director Lois Guthrie remembers some of CDSB's key moments

We can’t afford fragmented financial reporting

Hundreds of billions of dollars each year are spent on our fragmented financial reporting system. With CDSB’s announcement that it will sunset early next year and converge to form the International Sustainability Standards Board (ISSB), it is worth reflecting upon the foundational work CDSB and the sustainability reporting community have been involved in across the years, and how a great deal of it remains relevant to the future work of the ISSB.

6 characteristics of biodiversity assessment corporates need to know

Climate change is a human-induced phenomenon that has been etched in the 2015 Paris Agreement. Businesses are rolling out a barrage of actions to reduce emissions and conform to climate-risk disclosure regulations. With corporates grappling to meet their net-zero targets, new talk of nature-related risk disclosures, such as biodiversity, may seem overwhelming.

Water risks: why investors care about sustainability

Heatwaves and droughts are some of the effects of climate change that have become evident in recent years. The intensity and frequency of these occurrences has increased. But since these events are not new, it could be years before some people are motivated to address climate change. While the effects of climate change may therefore seem far removed, water-related risks are widespread. Water is arguably the medium through which we feel the effects of climate change most.

Value chain

How to prevent biodiversity loss through value chain tracking

Food production is the primary cause of global biodiversity loss (60-70%). At the same time, approximately one third of the food produced (1.3 billion tonnes) is wasted along the supply chain. Food waste increases pressure on agriculture and therefore drives biodiversity loss. Finding efficient ways to track value chains can reduce food waste.

3 water-related impacts to business you hadn’t thought of

Over 2 billion people live in countries with high water stress levels. Global water use has more than doubled in the last 40 years. Coupled with the effects of climate change, the strain intensifies.

Here are some of the good, bad and ugly moments of this London Climate Action Week webinar event.
