Review of Maritime Transport 2023: towards a green and just transition

UNCTAD’s Review of Maritime Transport 2023 calls for a “just and equitable transition” to a decarbonized shipping industry. The sector, whose greenhouse gas emissions have risen 20% over the last decade, operates an ageing fleet that runs almost exclusively on fossil fuels. As global leaders prepare for the next UN …

Net zero roadmap: a global pathway to keep the 1.5 °C goal in reach - 2023 update

Global warming could still be kept under 1.5°C due to rapid growth in clean energy technologies over the last decade, but the path is narrowing and stronger action needs to be taken swiftly, the International Energy Agency (IEA) has said in this report. In May 2021, the IEA published its …

Paris-consistent climate change mitigation scenarios: a framework for emissions pathway classification in line with global mitigation objectives

Since the adoption of the Paris Agreement, governments and economic actors have increasingly been setting greenhouse gas emissions reduction or net-zero targets. Amidst risks of delayed action and greenwashing, there is need to understand whether climate-related targets and transition plans are consistent with the Paris Agreement. Climate change mitigation scenarios …

Carbon and the fate of the Amazon

This publication shows that carbon prices exceeding US$ 20 per ton of CO2 captured by the natural regeneration of deforested areas in the Amazon would be truly transformative for the region’s landscape. Offsets for captured carbon would ensure forest integrity, inducing extensive forest restoration and the capture of 16 Gt …

Decarbonizing urban transport for development

he path to low-carbon urban transport looks fundamentally different in developed and developing countries. Most cities in developing countries have not yet developed their land use and transportation infrastructure around cars, leaving a window of opportunity to chart a new path to low-carbon, efficient and inclusive urban transport. While developed …

Vision 2050: update on the global zero-emission vehicle transition in 2023

This paper updates a 2022 ICCT study on the vehicle carbon dioxide (CO2) emissions impact of an accelerated global transition to zero-emission vehicles (ZEVs). It updates historical data through 2021 and 2022; accounts for policy developments in Zero Emission Vehicles Transition Council (ZEVTC) markets from August 2021 (the cut-off for …

Enabling frameworks for offshore wind scale up: innovations in permitting

This brief from IRENA's Collaborative Framework on Ocean Energy and Offshore Renewables presents actionable solutions to address permitting bottlenecks and accelerate related processes for scaling up offshore wind deployment. Offshore wind represents a key solution in meeting global climate goals, and an increasing number of countries are turning to this …

Steel decarbonisation in India

A clear definition of green steel is crucial for steelmakers to start investing in the right technologies, this new joint report by the Institute for Energy Economics and Financial Analysis (IEEFA) and JMK Research & Analytics finds. The report also provides various policy recommendations for the government to lay a …

Analysis of cost-effective reduction pathways for major emitting countries to achieve the Paris Agreement climate goal

This report presents cost-effective greenhouse gas emission reduction pathways for major emitting economies to keep global warming below 1.5 °C or well below 2 °C, as projected from least-cost scenarios of integrated assessment models in the IPCC AR6 scenario database. Achievement of the global climate goal of the Paris Agreement …

CO2 emissions from global shipping: a new experimental database

The shipping industry is essential for international trade, but it is also an important source of CO2 emissions. To make progress towards climate targets, countries need to monitor CO2 emissions from vessels owned by their ship operator companies. However, most shipping activity takes place outside national borders, making it more …
