Many countries have implemented national climate policies to accomplish pledged Nationally Determined Contributions and to contribute to the temperature objectives of the Paris Agreement on climate change. In 2023, the global stocktake will assess the combined effort of...
This paper in the Spring 2020 ifo DICE Report on carbon pricing discusses lessons that other regions could learn from European Union’s effort to implement carbon pricing through EU Emission Trading System (EU ETS).
Effective climate policy requires information from various scientific disciplines. Here, we construct a metamodel from climate and integrated assessment models that assesses the emissions budget, costs and uncertainty sources of achieving temperature targets. By calibrating...
The Sustainable Development Goals (SDGs) address food and nutrition security with goal number two. Food and nutrition security is a complicated issue, and understanding its future requires insights into (i) food availability, (ii) food access, (iii) food utilisation, and (iv)...
New synthesis shows what a wasted decade means for the climate pact made in Paris. New research shows that nations must now do much more and much faster to limit global warming to well below 2 °C, let alone 1.5 °C, as agreed in Paris.
This study investigates the progress of current mitigation actions undertaken by major emitting economies worldwide. It provides an in-depth analysis of the projected impact of currently implemented policies and compares this to the targets set by the countries in their...
The aim of this article is to provide an overview of greenhouse gas emission reduction potentials for 2030 based on the assessment of detailed sectoral studies. The overview updates a previous assessment that dates back more than ten years. We find a total emission reduction...
To guide policymaking, decision makers require a good understanding of the long-term drivers of food security and their interactions. Scenario analysis is widely considered as the appropriate tool to assess ‘wicked problems’, such as ensuring global food security, that are...
This report presents an analysis of published emission projections of Integrated Assessment Models (IAMs) and other, sectoral, models. At the moment, international aviation and shipping are underrepresented in most integrated assessment models. Improving the representation of...
De mondiale uitstoot van broeikasgassen is het afgelopen decennium gemiddeld met 1,5% per jaar gestegen, met alleen een wat lagere groei van 2014 tot 2016. In 2018 is de groei van de wereldwijde uitstoot van broeikasgassen hervat met 2,0% per jaar en steeg tot 51,8 gigaton...
