Shifting public and private investment from “brown” to “green” is an essential part of climate change. The post-2020 climate agreement to be agreed at COP 21 in December 2015 has the potential to play a significant role in signalling the importance of such a shift. This paper explores...

Greenhouse gas (GHG) emissions baselines are reference emissions levels. This paper focuses on projected forward-looking baselines that can be used both to inform national climate policy and to set goals that are defined relative to a business-as-usual (BaU) scenario. As some developing...

A key element in the success of limiting mean global surface temperature rise to below 2°C will be transformation of the energy sector globally. In addition to implementing already-available options for more efficient use of energy and low-emissions energy supply, action is needed now to put in...

An enhanced transparency framework will be a central component of the post-2020 international climate policy regime under the Paris Agreement, underpinning the dynamic process of updating nationally determined contributions (NDCs) and providing input to the global stocktakes of progress towards...
