This study assesses the environmental integrity risks of international carbon markets under Article 6 of the Paris Agreement and discusses possible international rules to address them. A considerable risk is that several countries have mitigation targets that correspond to higher levels of emissions than business-as-usual (BAU) projections.

This report details a study on whether countries should use certified emission reductions – or CERs – to achieve post-2020 targets under the Paris Agreement. The Clean Development Mechanism is the world’s largest greenhouse gas crediting mechanism and will continue to issue CERs until 2020.

Carbon markets are considered a key policy tool to achieve cost-effective climate mitigation1, 2. Project-based carbon market mechanisms allow private sector entities to earn tradable emissions reduction credits from mitigation projects. The environmental integrity of project-based mechanisms has been subject to controversial debate and extensive research1, 3, 4, 5, 6, 7, 8, 9, in particular for projects abating industrial waste gases with a high global warming potential (GWP).

This study systematically evaluates the environmental integrity of Joint Implementation (JI) in the first commitment period of the Kyoto Protocol. Analysis indicates that about three-quarters of JI offsets are unlikely to represent additional emissions reductions.

This working paper explores the question of target “time frame” and its implications for the generation and use of tradable emissions units.

At COP 17 in Durban, the Parties called for new market mechanisms, and more broadly, “various approaches, including markets” to “achieve a net decrease and/or avoidance of greenhouse gas emissions”.

For a long time, the Clean Development Mechanism (CDM) has been criticized for its cumbersome procedures and risks of weak environmental integrity.

This paper evaluates projects under the Clean Development Mechanism (CDM) that abate N2O emissions from adipic acid production. The research shows that carbon markets enabled N2O emissions abatement levels that had not previously been achieved.

The Clean Development Mechanism (CDM) under the Kyoto Protocol allows the crediting of emission reductions from greenhouse gas (GHG) abatement projects in developing countries. Designated Operational Entities (DOEs) are accredited third party entities

This report assesses the contribution of the CDM to meeting its environmental and sustainable development objectives and provides recommendations for improving the
