Looking behind IPCC’s WG3 climate finance figures

April 15, 2014 |


Last Sunday, the Intergovernmental Panel on Climate Change (IPCC) released the final version of the Summary for Policymakers for its working group dedicated to the assessment of the options for mitigating climate change. This is the first time an IPCC assessment report features a chapter dedicated to investment and finance. We are thrilled to see that the results draw heavily on CPI Climate Finance pioneering work in the field.

To demystify the term ‘climate finance’ and better understand the magnitude and type of climate financing available, CPI has provided an overview of the climate finance landscape for the past three years. Three particular objectives have guided our work:

(1)  identifying the main dimensions of climate finance,
(2)  highlighting issues and gaps in the tracking of flows, and
(3)  pointing to remedies when needed.

The third edition of this study, the Global Landscape of Climate Finance 2013 is the most comprehensive look at climate investment to-date.

$356-363 bn. went to climate finance projects in 2012…

The Summary for Policymakers indicates that “published assessments of all current annual financial flows whose expected effect is to reduce net GHG emissions and/or to enhance resilience to climate change and climate variability show USD 343 to 385 billion per year globally.” These numbers are taken from the 2012 edition of the Global Landscape of Climate Finance and are relative to the year 2011. We updated these numbers in the 2013 edition and found that climate investment plateaued at an average $359 billion in 2012, far short of even the most conservative estimates of the investment need.

A Wish List for IPCC: “Policy-Ready” Climate Science

October 9, 2013 |


Last week’s release of the IPCC Working Group I’s contribution to the Fifth Assessment Report (AR5) prompted a moment of self-reflection for the climate community.

It reported incremental gains in the scientific community’s confidence in its findings, with a few important tweaks to past findings. For example, it is now extremely likely (rather than just very likely) that human influence has been the dominant cause of observed warming since the mid-20th century (see C2ES’s table of increasing certainty). The Working Group also significantly revised the upper bound of their sea level rise estimates (see Nature’s News Feature on this topic).

However, there is a feeling that we have reached a point of diminishing returns in our current lines of inquiry. As a recent Nature editorial pointed out, comprehensive assessments of climate science may no longer represent the best use of our resources; continued investment in the IPCC process as it stands may result in smaller policy-relevant returns over time. We should feel a great sense of achievement and satisfaction at having reached this point. However, we may also need to sit back in our chairs, grab some old-fashioned writing implements, and reframe our questions.
