Global Carbon Account 2018

17 April 2018 - Climate Brief - By : Sébastien POSTIC, Phd / Clément METIVIER

I4CE‘s Global Carbon Account 2018 presents key trends regarding the implementation of explicit carbon pricing policies throughout the world in 2018.

 

 

5 key trends in 2018

  1. (Too) Few jurisdictions have implemented an explicit carbon price : as of April 1, 2018, 46 countries and 26 provinces or cities have adopted carbon pricing policies ;
  2. The adoption of carbon pricing policies is accelerating : in 2017, 3 ETS and 3 carbon taxes have been implemented, and more than 25 carbon pricing instruments have been announced for the years to come ;
  3. Carbon revenues represent an increasingly important financing tool for both the environment and the economy : I4CE estimates that carbon pricing initiatives generated USD 32 billion (EUR 26 billion) in revenues in 2017, up from USD 22 billion in 2016 ;
  4. Carbon prices are perceived as too low for the economic sphere : the explicit price of a CO2 ton in 2018 varies generally between less than USD 1 (EUR 1) and USD 139 (EUR 114) depending on the jurisdiction ;
  5. Explicit carbon prices in 2018 are not aligned with the 2°C trajectory.

A timeline, a world map, a detailed table and a graph provide comprehensive information on the jurisdictions that have implemented or plan to implement explicit carbon pricing policies, the type of instrument chosen, the sectors and fuels covered, the pricing levels, and the use of revenues.

    From targets to action: the climate finance agenda needs a new impetus in Belèm

    Ten years after the adoption of the Paris Agreement, what progress has been made to make financial flows consistent with a pathway towards low greenhouse gas emissions and climate-resilient development (the ambition set out in Article 2.1(c) of the Agreement)? And what is needed going forward? Although we still lack a comprehensive assessment of progress, this article draws on existing analysis of what can help align financial flows and examines the efforts made by governments and the financial sector to this end. It highlights a development in the debate towards a country-driven approach and a focus on real investment needs. It explores ways to overcome existing barriers to action despite a challenging global context. The article advocates that Article 2.1(c) should be viewed not as a stand-alone provision, but as something that requires full implementation of all the provisions of the Paris Agreement. It also calls for a shift from a target-focused to an action-focused finance agenda and discusses how the COP30 in Belém can contribute to this.

    What’s next for climate finance? From Seville to Belém

    With the dust settling from COP29’s hard-fought negotiations on the New Collective Quantified Goal (NCQG), attention is shifting to how the climate finance goal will be met. The challenge is how to scale up financing for increasingly connected priorities in a challenging landscape of debt stress and cuts in official development assistance.

    Bridging the gap: high-level climate & development finance commitments and the reality on the ground

    The 4th International Conference on Financing for Development (FFD4) in Seville represents a milestone for delivering on development (including climate action) goals, a decade after the adoption of the Sustainable Development Goals and the Paris Agreement. The “Seville Commitment” was adopted on June 30th, albeit in the absence of the United States – demonstrating that widespread support remains for a comprehensive package to finance development. However, the outcome also embodies the growing chasm between high-level commitments and the reality of financing for development and climate action on the ground. Recent research by I4CE attempts to bridge this gap on two crucial issues.
