This report reviews how governments can raise new funds and align existing finance with their climate commitments. It provide an overview of the landscape of instruments available to governments as they seek to finance their NDCs — from green bonds to regulatory interventions. It also looks at options for monitoring government success in shifting funds toward their commitments.

The report provides a comprehensive assessment of the global gap in climate action across the world’s highest-emitting systems, highlighting where recent progress made in reducing GHG emissions, scaling up carbon removal, and increasing climate finance must accelerate over the next decade to keep the Paris Agreement’s goal to limit warming to 1.5°C within reach.

This report takes stock of countries’ latest NDCs and examines how these commitments have evolved since the Paris Agreement entered into force, identifying overall trends and pinpointing the elements where further action is needed. It finds that countries are making incremental progress on strengthening their NDCs, but what we really need to achieve the goals of the Paris Agreement is urgent transformational change.

This report proposes a roadmap for zero emissions for Hong Kong's road transport sector, focusing on the bus, private car and freight vehicle segments.

The report estimates the socioeconomic impact of federal climate policies under three mitigation scenarios.
