An IPCC special report on the impacts of global warming of 1.5 °C above pre-industrial levels and related global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty.

GHG Protocol

Greenhouse Gas Protocol provides standards, guidance, tools and training for business and government to measure and manage climate-warming emissions.


The Science Based Targets initiative drives ambitious climate action in the private sector by enabling organizations to set science-based emissions reduction targets.

International Platform for Insetting

The International Platform for Insetting (IPI) is a collaborative membership organisation for businesses implementing insetting projects that achieve positive impacts for the environment and communities along their value chains.


The CDM allows emission-reduction projects in developing countries to earn certified emission reduction (CER) credits, each equivalent to one tonne of CO2. These CERs can be traded and sold, and used by industrialized countries to a meet a part of their emission reduction targets under the Kyoto Protocol.


ISO (International Organization for Standardization) is an independent, non-governmental international organization with a membership of 167 national standards bodies.

Integrity Council for the Voluntary Carbon Market

The Integrity Council for the Voluntary Carbon Market (Integrity Council) is an independent governance body for the voluntary carbon market. Their purpose is to ensure the voluntary carbon market accelerates a just transition to 1.5ºC. 

They do this by setting and enforcing definitive global threshold standards, drawing on the best science and expertise available, so high-quality carbon credits channel finance towards genuine and additional greenhouse gas reductions and removals that go above and beyond what can otherwise be achieved, and contribute to climate resilient development.
