Countries’ climate pledges built on flawed data, Post investigation finds
As tens of thousands of people are convening in Glasgow for what may be the largest-ever meeting of the United Nations Framework Convention on Climate Change (UNFCCC), also known as COP26, the numbers they are using to help guide the world’s effort to curb greenhouse gases represent a flawed road map.
That means the challenge is even larger than world leaders have acknowledged.
“In the end, everything becomes a bit of a fantasy,” said Philippe Ciais, a scientist with France’s Laboratory of Climate and Environmental Sciences who tracks emissions based on satellite data. “Because between the world of reporting and the real world of emissions, you start to have large discrepancies.”
The UNFCCC collects country reports and oversees the Paris agreement, which brought the world together to progressively reduce emissions in 2015. The U.N. agency attributed the gap that The Post identified to “the application of different reporting formats and inconsistency in the scope and timeliness of reporting (such as between developed and developing countries, or across developing countries).”
When asked if the United Nations plans on addressing the gap, spokesman Alexander Saier said in an email it is continuing its efforts to strengthen the reporting process: “However, we do acknowledge that more needs to be done, including finding ways to provide support to developing country Parties to improve their institutional and technical capacities.”
The gap comprises vast amounts of missing carbon dioxide and methane emissions as well as smaller volumes of powerful synthetic gases. It is the result of questionably drawn rules, incomplete reporting in some countries and apparently willful mistakes in others — and the fact that in some cases, humanity’s full impacts on the planet are not even required to be reported.
The Post’s analysis is based on a data set it built from emissions figures countries reported to the United Nations in a variety of formats. To overcome the problem of missing years of data, reporters used a statistical model to estimate the emissions each country would have reported in 2019, then compared that total to other scientific data sets measuring global greenhouse gases. . .
At the verge of the abyss
The emissions reports are so unwieldy that the United Nations does not have a complete database to track country emissions. Some 45 countries have not reported any new greenhouse gas numbers since 2009.
> A key problem is that the U.N. reporting guidelines don’t currently require any atmospheric or satellite measurements, known as a “top-down” approach. .
Without requiring satellite or atmospheric measurements, richer and poorer countries alike are likely to underreport for years to come. . ."
