Global Energy Transitions Stocktake
Tracking progress toward the Paris Agreement

This year marks the finalisation of the first Global Stocktake of the Paris Agreement, which assesses the world’s collective progress against its climate goals. In support of that important effort, the IEA is bringing together all of its latest data on clean energy transitions in one place, making it freely accessible to citizens, governments, and industry. This page, which will be consistently updated in the lead up to COP28, includes a calendar of all major releases throughout the year, making it easy to follow the latest updates and find links to IEA’s reports and in-depth analysis.

Global tracking indicators
Global CO2 emissions from energy combustion and industrial processes, 1900-2022
OpenCO2 Emissions in 2022: Growth in emissions lower than feared
In a year marked by energy price shocks, rising inflation, and disruptions to traditional fuel trade flows, global growth in emissions was lower than feared, despite gas-to-coal switching in many countries. Increased deployment of clean energy technologies such as renewables, electric vehicles, and heat pumps helped prevent an additional 550 Mt in CO2 emissions.
Global methane emissions from the energy sector, 2000-2022
OpenMethane emissions remained stubbornly high in 2022
Increase in heat pumps sales in selected regions and globally, 2021 compared to 2020
OpenIn 2021 heat pump sales grew by nearly 15%
Global electric car stock, 2010-2021
OpenSales of electric cars doubled in 2021
Total renewable capacity additions, 2002-2022
OpenAnnual renewable capacity additions broke a new record in 2021
Higher fossil fuel prices have also improved the competitiveness of solar PV and wind generation. The world is set to add as much renewable power in the next 5 years as it did in the previous 20 years, overtaking coal to become the largest source of global electricity by early 2025. Global capacity additions will be driven by Europe, China, the US and India, which are all speeding up policies and introducing regulatory and market reforms to combat the energy crisis.
Global public energy RD&D budget, 2015-2021
OpenGovernment spending on energy RD&D could reach USD 40 billion in 2022
Government spending for clean energy investment support and short-term consumer energy affordability measures, July 2021 - November 2022
OpenGovernments have allocated USD 1.2 trillion to clean energy since the pandemic
In addition, policymakers have spent a further USD 630 billion in efforts to protect households and businesses from rising energy bills since autumn 2021. Only about 35% of these short-term affordability measures were targeted towards the most needy households or to businesses most exposed to the effects of high energy prices. Without better targeting, new affordability measures will further contribute to rising levels of government debt.
Global energy investment, 2017-2022
OpenGlobal clean energy spending is ramping up
Key indicators related to energy investment, 2021
OpenOnly 20% of clean energy investment occurs in emerging and developing economies
The clean energy economy is gaining ground, but greater efforts are needed
Global CO2 emissions changes by technology maturity category in the Net Zero Scenario, 2050 compared to 2030
OpenHalf the emission reductions needed to reach net zero come from technologies not yet on the market
Energy-related and process CO2 emissions by scenario, 2010-2050
OpenMeeting all net zero pledges on time and in full would result in 1.7 °C of temperature rise in 2100
However, neither would be enough to keep the temperature rise to “well below 2 °C" nor reflect efforts “to limit the temperature increase to 1.5°C above pre-industrial levels.” In the Net Zero Emissions by 2050 (NZE) scenario, CO2 emissions drop to zero in 2050 with temperature rise peaking below 1.6 °C around 2040, before falling to around 1.4 °C in 2100.
International collaboration needs to accelerate on key sectors
Number of people without access to electricity in sub-Saharan Africa and the world, 2012-2022
OpenFor the first time in decades, the number of people without access to electricity is set to increase in 2022
According to the latest IEA estimates, the number of people around the world who live without electricity is set to rise by nearly 20 million in 2022, reaching nearly 775 million, the first global increase since the IEA began tracking the numbers 20 years ago. The rise is mostly in sub-Saharan Africa, where the number of people without access is nearly back to its 2013 peak, erasing years of improvements.
Energy employment in fossil fuel and clean energy sectors, 2019-2022
OpenClean energy employs over 50% of total energy workers
Global electrolyser capacity by size, 2018-2021
OpenThe pipeline of low-emission hydrogen projects is growing
Country-level tracking indicators
Moving to sustainable energy systems is a global challenge that involves a multitude of decisions taken at national and local levels. Not every country starts from the same position, and not every country can or will seek the same solutions. That will depend on the structure of its economy, its legacy energy mix, and factors such as climate and geography.
