Vulnerable developing countries lead world on climate ambition: UN report. Developing countries are leading the world in responding to climate change, according to a new report which calls for bold, urgent action to limit the impacts of global warming.

Argentina has shown many positive developments in the climate space since 2015, but Argentina’s climate commitment in 2030 is not consistent with holding warming below 2°C, let alone limiting it to 1.5°C as required to achieve the Paris Agreement.

This study assesses the fuel efficiency of U.S. airlines on domestic operations in 2017 and 2018. Revenue passenger miles (RPMs) increased 10% and departures increased by 4% from 2016 to 2018. Fuel efficiency in terms of RPMs per gallon of fuel consumed improved by 3%.

New report provides first-ever estimate of health care’s global climate footprint, calls for zero emissions.

China’s internet data center industry emitted an estimated 99 million tonnes of CO2 in 2018, new research from Greenpeace East Asia and the North China Electric Power University shows. Researchers found that increasing the sector’s renewable energy intake by 7% over the next five years would reduce carbon emissions by 16 million tonnes.

Reducing CO2 emissions from all new cars and accelerating the uptake of zero emission models is essential to prevent a climate emergency. This is not a silver bullet - local and national policies need to reduce car ownership and use and promote active travel and shared mobility, which are also important.

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

This study examines the drivers of both the previous decline in global energy-related CO2 emissions, and their subsequent growth in recent years (in the EU, US, India and China), and argues that this trend was in neither case a good indicator of climate policy effort or effectiveness.

To achieve the Paris Agreement goals and limit global temperature rise this century to 1.5°C, the global economy must be rapidly transformed. A carbon price is needed to incorporate climate change costs into economic decision-making to significantly reduce U.S. greenhouse gas emissions, particularly in the electricity sector.
