The South Asia region is both a large contributor to climate change and also one of the regions most vulnerable to climate change. This paper provides an overview of the region’s vulnerabilities, national committments to mitigate emissions, and national policies to adapt to a changing climate.

“Nature-based solutions” (NbS) have been defined as “actions to protect, sustainably manage and restore natural or modified ecosystems that address societal challenges…”. The societal challenge to which NbS are most commonly applied at present is the mitigation of climate change.

This paper studies the effect of climate change mitigating policies on innovation in clean energy technologies. Results suggest that the tightening of environmental policies since the early 1990s have made a statistically and economically significant contribution to the increase in clean innovation.

This technical note describes a method for determining whether and to what extent Parties to the Paris Agreement have enhanced their nationally determined contributions (NDCs) with respect to greenhouse gas (GHG) mitigation.

CCS is one of many climate mitigating technologies that is mature, commercially available, and absolutely necessary to achieve global net-zero ambitions and a stable climate. The total installed CCS capacity must increase 100-fold by 2050 to limit global warming to below 2° Celsius.

The paper examines climate mitigation strategies to reach net-zero emissions by mid-century, focusing on smoothing macroeconomic costs in the short- to medium-term—the horizon relevant for policymakers.

Putting a price on carbon can be an indispensable part of a country’s strategy to reduce emissions in an efficient way. Furthermore, putting a price on carbon through international carbon markets can also offer significant cost benefits and enable flexibility in achieving emission reduction targets.

Science–policy interactions are exchanges among key stakeholders looking to reconcile value systems and interests to ultimately, influence decision-making processes through knowledge exchange and generation.

Many developing countries consider that international support is vital for achieving their climate targets and accelerating actions, pledged in the so-called Nationally Determined Contributions (NDCs), under the Paris Agreement.
