NEW ANALYSIS: Global Carbon Markets Can More than Meet Civil Aviation Demand

MARCH 10, 2020 / Global airlines are committed to delivering “carbon neutral growth” in flights between countries, even if international air traffic doubles or triples, as some are projecting. That commitment kicks in next year, and a key vehicle for meeting it is the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA).

Created through the UN’s International Civil Aviation Organization (ICAO), CORSIA will only deliver carbon-neutral growth if it recognizes a universe of offsets that’s large enough to meet variable demand but small enough to incentivize new activities that reduce emissions. A new analysis by Ecosystem Marketplace finds that current proposals do just that. Click here to download.

State of the Voluntary Carbon Markets 2019

We invite you to download our latest report, “Financing Emissions Reductions for the Future – State of Voluntary Carbon Markets Report 2019. The report consists of three sections, Market Overview, which includes data from 2017 and 2018, Market Dynamics, which details trends observed in 2019 and Market Direction, which offers observations on market forces in 2020 and beyond. Previous reports and additional resources are available below.



Ecosystem Marketplace was initially created to improve transparency and price discovery in the voluntary space, as there is no centralized system for transacting voluntary carbon credits. Between 2006 and 2018, our team has annually distributed surveys to our network of project developers, investors, retailers, and brokers to collect confidential information about their voluntary carbon offset market transactions. The resulting reports, provided free of charge, provide all market participants – from small project developers to large corporate buyers to policymakers – a comprehensive view of market conditions.

We are pleased to present the State of the Voluntary Carbon Markets 2019, which includes data collected for calendar years 2017 and 2018. Also included are insights compiled through interviews with a diverse set of market participants covering trends through late 2019.

It’s worth underscoring that the figures and trends described in this report focus on transactions of carbon offsets for voluntary purposes. Although the lines between compliance and voluntary markets are blurring, with standards once established for voluntary transactions increasingly being considered for inclusion in compliance markets, all data herein relates to voluntary transactions. Simply put, if the credit is being used to satisfy a regulatory requirement, it is not considered voluntary and not covered in this report.

This report does, however, discuss the evolution of certain compliance markets, such as the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), and certain national and subnational markets, to the extent that they form the boundaries of and influence what is considered “voluntary.”

If you received the survey but did not submit your 2017 or 2018 data, or if you’re a project developer, retailer or broker and were not contacted in 2019, it’s not too late to further enrich our dataset.

Even as we move into 2020, we will continue to conduct analysis with historical data, so please let us know if you have requests or would like to discuss additional analysis you’d like to see.

The survey shouldn’t take more than 15-30 minutes to respond. Click here to access our 2019 survey.
