The world is not on track to reduce greenhouse emissions to net zero and minimize the effects of climate change. Policies can reduce emissions. However, evidence on their effect and relationship with other emissions drivers is incomplete. To identify which policies can catalyse emissions reductions – and under which circumstances – remains a challenge. This knowledge can help accelerate mitigation efforts. I proposed to use data mining to explore the relationship between the adoption of climate change mitigation policies and emissions trends. This will generate evidence on policies’ historical impact and provide insights into their future role.
