This report updates a working paper released last year, and details a global, transparent, and geographically allocated carbon dioxide (CO2) inventory for three years of commercial aviation. For the first time, we estimate absolute emissions and carbon intensity per passenger by both seating class and aircraft class.

This brief analyses four key sectors of the manufacturing industry: iron and steel, cement, ammonia and chemicals (primarily petrochemicals), which have the highest emissions intensity of production. The analysis reveals that the opportunities to decarbonise the manufacturing sector are aplenty.

Cities worked together to summarize the most relevant information and actionable findings related to the latest science on 1.5°C.

Carbon pricing is the most cost-effective policy to address the climate challenge. Following the Paris Agreement, a first acceleration in the implementation of carbon pricing schemes has been observed and can expect a further acceleration over the next few years, as countries ratchet up their climate goals under their Paris commitments.

Carbon capture, utilisation and storage will be an important part of the portfolio of technologies and measures needed to achieve climate and energy goals.

This policy brief presents insights that can be derived from the gap indicators in the ‘global stocktake’ dynamic web tool. Know that there is a global emissions gap, as current policies on the national level are insufficient to accomplish the objective of the Paris Agreement to keep temperature increase to well below 2 °C.

Hydrogen and fuel cell technologies have experienced cycles of high expectations followed by impractical realities. This time around, however, falling renewable energy and fuel cell prices, stringent climate change requirements and the discrete involvement of China are step changes.

This study uses a computable general equilibrium model to analyze various policy scenarios for a carbon tax on greenhouse gas emissions from petroleum fuels and kerosene in Ethiopia. The carbon tax starts at $5 per ton of carbon dioxide in 2018 and rises to $30 per ton in 2030.

This sets out the impact of current global policies, the changes in the global fleet and new global efficiency targets to accelerate the uptake of clean and efficient vehicles for vehicle efficiency.

A sustainable path to development has profound consequences for all economic activities and related policies. The mining industry, which provides input to almost every product and service in the world, is highly relevant to the goal of achieving sustainable development in mineral-rich countries and in the global economy.
