Germany’s proposed 2030 national target not yet 1.5˚C-compatible

To be in line with the 1.5°C limit of the Paris Agreement, Germany’s new 2030 domestic reduction target should aim for national emission reductions of at least 69% below 1990 levels. To fully contribute its fair share Germany would have to significantly increase its international climate finance. The programme to …

China’s greenhouse gas emissions exceeded the Developed World for the first time in 2019

Each year Rhodium Group provides the most up-to-date global and country-level greenhouse gas (GHG) emissions estimates through the ClimateDeck (a partnership with Breakthrough Energy). In addition to the preliminary US and China GHG estimates for 2020, Rhodium provides annual estimates of economy-wide emissions—including all six Kyoto gases—for over 190 countries …

Climate summit momentum: Paris commitments improved warming estimate to 2.4°C

In this briefing, the Climate Action Tracker (CAT) estimates global warming by 2100 to be at an all-time low of 2.4°C. Due to recent climate action announcements at President Biden’s Leaders Summit on Climate, together with those announced since September 2020, have improved the CAT’s global warming estimate by 0.2°C. …

National 1.5°C compatible emissions pathways and consistent power sector benchmarks: Indonesia, Viet Nam, Philippines, India and Japan

This report presents domestic emissions pathways required to keep to the Paris Agreement’s 1.5°C limit for five countries: Viet Nam, Philippines, India, Indonesia and Japan and assesses if current 2030 climate targets are in line with these pathways. Pathways are derived from the pathways assessed in the IPCC Special Report …

A pathway to carbon neutral agriculture in Denmark

This report discusses how Denmark - a country whose major agricultural organizations have committed to become carbon neutral by 2050 - can achieve carbon neutral agriculture. The report’s lessons can inform not only Denmark’s agricultural future, but also that of other advanced agricultural economies.

Air quality and climate policy integration in India; frameworks to deliver co-benefits

In 2019 alone, India experienced an estimated 1.2 million air pollution-related premature deaths. At the same time, India’s growing economy is driving CO2 emissions, which increased by more than 55% in the last decade, and are expected to rise by 50% to 2040. Today’s energy choices matter for future development, …

Exploring the impact of shared mobility services on CO2

Policy action to avoid the impending societal costs of climate change is particularly warranted in transport sector, which is responsible for 30% of greenhouse gas emissions in OECD countries. To design appropriate interventions in this sector, policy makers should account for the recent emergence of shared mobility services in urban …

Towards common GHG inventory reporting tables for Biennial Transparency Reports: Experiences with tools for generating and using reporting tables under the UNFCCC

Under the Enhanced Transparency Framework (ETF) of the Paris Agreement, Parties will be required to report information on national GHG inventories using a set of Common Reporting Tables (CRTs). The CRTs can provide an important source of data at the international and national levels. While a final set of tables …

Global energy review 2021: Assessing the effects of economic recoveries on global energy demand and CO2 emissions in 2021

Global energy-related carbon dioxide emissions are estimated to increase by 1.5 billion tonnes in 2021 - the biggest annual rise in emissions since 2010, according to the International Energy Agency (IEA). This increase to be driven by a strong rebound in demand for coal in electricity generation will reverse the …

The role of LNG in the transition toward low- and zero-carbon shipping

Liquefied natural gas (LNG) used as a bunker fuel has the potential to offer important reductions in atmospheric pollution—that is, air pollutants and greenhouse gas (GHG) emissions - from ships. Compared to traditional oil-derived bunker fuels such as heavy fuel oil (HFO), LNG clearly emits significantly lower quantities of sulfur …
