Global Carbon Accounts in 2021

21 October 2021 - Climate Report - By : Marion FETET / Sébastien POSTIC, Phd

Explicit carbon pricing systems – a tax or a carbon market – continue to develop around the world. In the 2021 edition of its Global Carbon Accounts, I4CE presents the main trends and provides an overview of these public policies: the countries that have adopted them, the sectors covered, the price levels, the revenues generated and what is being done with them. Find all this information in graphics.

 

 

The 4 trends of 2021

  1. As of October 1st, 2021, 47 jurisdictions (countries, provinces, or cities) are operating a carbon pricing scheme (carbon tax and/or an Emissions Trading System (ETS)). Together, they account for around 60% of global gross domestic product (GDP). Over the past year, two G20 countries have implemented an explicit price on carbon: China and Germany.
  2. Carbon pricing schemes generated USD 56.8 billion (EUR 49 billion) over the FY 2020-2021; a significant increase compared with the previous fiscal year (USD 48 billion). 52% of this revenue stems from carbon taxes. The other 48% of revenue comes from ETS auctions. These carbon revenues are mostly directed to national general budgets or are earmarked for specific environmental or development projects.
  3. As of October 1st, 2021, explicit carbon prices range from less than USD 1 to USD 142 (EUR 117) per ton of CO2e. Yet, more than 46% of emissions regulated by carbon pricing are still covered by a price below USD 10 (EUR 8). To stay on the 2°C trajectory while sustaining economic growth, the High-Level Commission on carbon prices led by economists Stern and Stiglitz recommends reaching carbon prices comprised between USD 40 and USD 80 per ton of CO2e by 2020, and between USD 50 and USD 100 per ton of CO2e by 2030.
  4. Together, jurisdictions with a carbon mechanism (tax or ETS) emit 60% of global greenhouse gas (GHG). This does not mean that 60% of global emissions are effectively covered by a carbon price: some sectors or populations may be exempted (totally or partially) for various reasons.
    Furthermore, fossil fuel subsidies still represent at least USD 450 billion in 2020 (see page 4).

    Social and Climate Budget Tagging: Insights from Indonesia

    Attention is growing to the need to tackle climate and social issues jointly. Indeed, both climate change and climate policies affect social issues such as poverty, inequality, or access to healthcare. A well-known example is that of carbon pricing, a climate policy which can have regressive effects in some contexts. As another example, climate change induced heatwaves are disproportionately likely to impact poorer individuals who typically have more constrained access to healthcare, physical jobs in outdoor conditions, and through indirectly driving up food prices. To foster an effective and sustainable transition to low-carbon and resilient economies, policymakers need to ensure individuals do not lose more from climate policies than they already lose from the effects of climate change, but instead benefit from them.

    After Bonn and towards COP 29: the battle on finance and the role of financing plans for the transition

    Tense climate negotiations just ended in Bonn with limited progress on finance and the revised climate commitments under the Paris Agreement. During the opening ceremony of the sixtieth sessions of the subsidiary bodies (SB 60) of the United Nations Framework Convention on Climate Change (UNFCCC), Simon Stiell –Executive Secretary– highlighted the need to “make serious progress on finance, the great enabler of climate action” and to aim for bolder, broader and inclusive third generation Nationally Determined Contributions (NDCs 3.0) that “can serve as blueprints to propel economies and societies forward and drive more resilience”.

    Carbon pricing revenues: their role in financing the climate transition

    Last month, the Executive Secretary of the UNFCCC, Simon Stiell, stressed how important this and next year are for the achievement of the Paris Agreement and called for “a quantum leap in climate finance” ahead of the Spring Meetings of the World Bank Group and International Monetary Fund. Indeed, with emissions required to peak before 2025, our window of opportunity is rapidly closing to keep 1.5°C within reach. More and better finance is urgently needed. Carbon pricing policies and their revenues are part of the tools available that can help fill the climate finance gap.
