Key takeaways
  • In order to counter the climate crisis, more than 139 countries have set a NZE (Zero Net Emissions) target to be reached by the year 2050.
  • The Race to Zero project is aimed at private and sub-national actors, who commit to halve global emissions by 2030.
  • The OECD has developed IPAC, a climate measurement and assessment tool to help countries get an overview of their situation.
  • IPAC has four tools: an indicator table; an annual tracking monitor; a scoring and guidance tool; and an interactive platform.
  • While countries are making progress in their climate actions, current commitments are not meeting the targets set: IPAC aims to support and guide countries in this process.

In line with the primary tar­get set for COP26 in Glas­gow in 20211, more and more coun­tries are com­mit­ting to achieve zero net emis­sions (NZE2) by the middle of this cen­tury and to strengthen their nation­ally determ­ined con­tri­bu­tions (NDCs3) by 2030. Today, more than 139 coun­tries and uni­ons, includ­ing China, the United States and the European Uni­on, cov­er­ing about 83% of glob­al emis­sions, have announced this NZE target.

Moving towards Zero Carbon

Sub-nation­al act­ors and the private sec­tor are also step­ping up their own com­mit­ments to reduce emis­sions, includ­ing through the Race to Zero campaign.

Launched at the UNSG Cli­mate Action Sum­mit 2019 by Chilean Pres­id­ent Sebastián Piñera, Race to Zero mobil­ises act­ors out­side nation­al gov­ern­ments to join the Cli­mate Ambi­tion Alli­ance and com­mit to halv­ing glob­al emis­sions by 2030. As of Septem­ber 2022, 11,309 non-state act­ors have com­mit­ted to the cam­paign, includ­ing 8,296 com­pan­ies, 593 fin­an­cial insti­tu­tions, 1,136 cit­ies, 52 states and regions, 1,125 edu­ca­tion­al insti­tu­tions, 64 health insti­tu­tions and 29 oth­er organisations.

But do we really have the tools to assess and meas­ure these com­mit­ments? Not really, and it is to fill this gap that the OECD has developed an innov­at­ive tool for meas­ur­ing and assess­ing nation­al com­mit­ments: the Inter­na­tion­al Pro­gramme for Cli­mate Action (IPAC).

IPAC, a framework for countries to follow

Ini­tially pro­posed by France and pub­licly sup­por­ted by Pres­id­ent Mac­ron on the occa­sion of the OECD’s 60th anniversary in Decem­ber 2020, IPAC was launched in May 2021 and is based on four components:

  • First, a dash­board of cli­mate-related indic­at­ors, meas­ur­able and agreed between coun­tries for use in monitoring.
  • Second, an annu­al cli­mate action mon­it­or, based on the pre­vi­ous dash­board, provides a sum­mary of coun­tries’ pro­gress towards their own cli­mate and sus­tain­able devel­op­ment goals. This mon­it­or provides examples of good prac­tice and res­ults in cli­mate mit­ig­a­tion and adaptation.
  • This is fol­lowed by a coun­try rat­ing tool based on envir­on­ment­al, social and geo­graph­ic­al indic­at­ors and con­tain­ing tar­geted policy advice to help design eco­nom­ic­ally viable mit­ig­a­tion and adapt­a­tion actions.
  • Finally, an inter­act­ive plat­form for dia­logue and mutu­al learn­ing between coun­tries with dis­cus­sion top­ics on innov­at­ive approaches and good practices.

The philo­sophy behind this approach is to avoid inef­fect­ive or coun­ter­pro­duct­ive policies, which is easi­er said than done giv­en the scale of the response required and the need to con­stantly adapt to chan­ging nation­al and glob­al cir­cum­stances. IPAC fun­da­ment­ally addresses the need for decision-makers to have access to com­pre­hens­ive cli­mate data and tools for mean­ing­ful mon­it­or­ing, bench­mark­ing, and policy analysis.

Using IPAC, gov­ern­ments are able to see where they are, where they are going and how they can improve.

The bene­fit of these four IPAC tools is that decision-makers can get both a gran­u­lar and com­pre­hens­ive over­view of all rel­ev­ant cli­mate-related data: emis­sions and their causes, risks and impacts, and responses and actions. In addi­tion, through its research and ana­lys­is of over 50 coun­tries, the IPAC team is able to har­ness and com­mu­nic­ate the breadth and depth of the data col­lec­ted, shar­ing best prac­tices and encour­aging stake­hold­ers to learn from each oth­er. There­fore, by using the tools and inform­a­tion col­lec­ted by IPAC, gov­ern­ments can see the big­ger pic­ture: where they are, where they are going and how they can improve.

At COP27 in Sharm El Sheikh, OECD Sec­ret­ary-Gen­er­al Math­i­as Cor­mann presen­ted the tool as part of a roundtable dis­cus­sion at the French Pavil­ion on 7 Novem­ber 2022, with Agnès Pan­ni­er-Run­acher, France’s Min­is­ter for Energy Trans­ition; Espen Barth Eide, Min­is­ter of Cli­mate and Envir­on­ment in Nor­way; Max­imili­ano Proaño Ugalde, Under­sec­ret­ary of the Envir­on­ment in Chile and Johan Rock­ström, Co-Dir­ect­or of the Pots­dam Insti­tute for Cli­mate Impact Research.

What remains to be done in France?

These indic­at­ors play a key role in the second annu­al cli­mate report to be pub­lished in Novem­ber 2022: it high­lights coun­tries’ expos­ure to cli­mate-related risks, which are increas­ing in fre­quency and intens­ity. To suc­cess­fully mit­ig­ate and adapt to these risks, this year’s IPAC Mon­it­or advises gov­ern­ments to use all policy tools and mech­an­isms (non-mar­ket, mar­ket, etc.) at their dis­pos­al, as well as to increase the strin­gency of their measures.

In the case of France, IPAC shows for example that GHG emis­sion intens­it­ies per unit of GDP and per cap­ita are decreas­ing. This means that, over­all, France is decoup­ling emis­sions from both eco­nom­ic out­put and pop­u­la­tion growth.

On the oth­er hand, the per­cent­age of the pop­u­la­tion exposed to sum­mer days with tem­per­at­ures above 35°C is increas­ing. Accord­ing to the IPAC score­board, this indic­at­or helps to under­stand the pos­sible risks of extreme tem­per­at­ures for the pop­u­la­tion. We should keep in mind that France can­not be sat­is­fied with mit­ig­at­ing long-term chron­ic risks and must find solu­tions to deal with acute risks, such as heat­waves, to which it is increas­ingly vulnerable.

In terms of “actions and oppor­tun­it­ies”, we find that France is increas­ingly adopt­ing cli­mate policies, but is not yet adopt­ing the full range of avail­able policy options as meas­ured by the OECD, rep­res­en­ted by the dot­ted line (OECD, 2022). 

Fur­ther­more, it appears that France has cur­rently adop­ted the largest share of avail­able policies tar­get­ing all sec­tors, fol­lowed by those tar­get­ing the build­ing sec­tor. Giv­en that the French cli­mate strategy pri­or­it­ises energy effi­ciency in build­ings, it appears that policy mak­ing here is aligned with nation­al and muni­cip­al tar­gets. Nev­er­the­less, France has the oppor­tun­ity to adopt a broad­er set of policies, espe­cially those related to the elec­tri­city sec­tor, where it is lag­ging behind.

In tack­ling cli­mate change, every coun­try goes through the inev­it­able pro­cess of determ­in­ing the most effect­ive policies in a con­stantly chan­ging nation­al and inter­na­tion­al con­text. The urgency to find solu­tions con­tin­ues to grow, and while coun­tries have cer­tainly shown pro­gress in their actions and ambi­tions, cur­rent nation­al cli­mate com­mit­ments are still not suf­fi­cient to meet the goals of the Par­is Agree­ment. Moreover, while coun­tries need to “scale up” their com­mit­ments, many are strug­gling to meet their cur­rent tar­gets. This OECD ini­ti­at­ive there­fore provides much-needed sup­port and encour­ages stake­hold­ers not to shoot blind, but to rely on hol­ist­ic and data-driv­en tools.

Addi­tion­al data on emis­sions, impacts, risks, actions, and oppor­tun­it­ies are avail­able in the IPAC dashboard.

1The Par­is Agree­ment’s goal of lim­it­ing glob­al warm­ing to 1.5° means redu­cing emis­sions by 45% by 2030 and achiev­ing net zero emis­sions by 2050.
2“Net zero emis­sions” means that green­house gas emis­sions are reduced to as close to zero as pos­sible, with the remain­ing emis­sions in the atmo­sphere being reab­sorbed (e.g. by the oceans and forests).
3A “Nation­ally Determ­ined Con­tri­bu­tion” is a cli­mate plan to reduce emis­sions and adapt to the effects of cli­mate change. Each Party to the Par­is Agree­ment is required to estab­lish an NDC and update it every five years. The Glas­gow cli­mate pact of Novem­ber 2021 requires the tar­gets in the NDCs to be reviewed and strengthened in 2022, with increased ambi­tion, fur­ther emis­sion reduc­tions and broad­er adapt­a­tion meas­ures.
