Thomas Day analyses carbon market mechanisms, corporate climate commitments and national level climate policy at NewClimate Institute. Thomas has more than 10 years of experience in the climate policy field.  Thomas’ recent work on corporate net-zero targets and carbon neutrality claims – including his co-authorship of the Corporate Climate Responsibility Monitor – has demonstrated the need for greater guidance and scrutiny in corporate climate planning and offsetting claims. Thomas’ extensive research on Kyoto-era market mechanisms contributed towards a significant global knowledge gap on the current situation of mitigation activities under global carbon markets. This research has been influential for informing the debate on the potential risks and safeguards associated with different options for the use of offsetting credits post-2020, with particular relevance for the analysis of voluntary carbon markets and corporate net-zero targets. At the national climate policy planning level, Thomas provides direct advisory support to governments with regards to their climate change planning processes and the development of climate change mitigation policy. In this capacity, Thomas' work with the governments of Mongolia, Kenya and Georgia has included support for the development of national climate action plans, Nationally Determined Contributions (NDCs) and long-term decarbonisation pathways, as well as consultation on the different options for interaction with Article 6 mechanisms.
