The SDG Reckoning Report - Can the world catch up?

The next few years will be absolutely pivotal to closing the annual SDG financing gap – estimated to be around US$2.5 trillion. The annual "M&G SDG plc Reckoning report", issued by our parent company M&G plc since 2020, recalled that the scale of financial flows addressing the SDGs is insufficient. It is evident that both the public and private sector must augment action and direct capital towards addressing global problems such as food insecurity, health inequalities, discrimination, pollution, global warming and habitat loss.

Please note, while we support the UN SDGs, we are not associated with the UN and our funds are not endorsed by them.


You have to focus on positive impact companies generating or directing their business towards big social, environmental challenges as a core part of what they do and the impact has to be measurable.
