Yes, carbon emissions fell during COVID-19. But it’s the shift away from coal that really matters

Much has been made of the COVID-19 lockdown cutting global carbon emissions. Energy use has fallen over recent months as the pandemic keeps millions of people confined to their homes, and businesses closed in many countries. Projections suggest global emissions could be around 5% lower in 2020 than last year. Flickr/David Clarke Frank Jotzo, Australian […]

Learning from the contentious history of carbon removal

Large-scale carbon dioxide removal (CDR), also referred to as “negative emissions”, is increasingly seen as a key component of climate change mitigation pathways that limit warming to 1.5C or 2C. By Dr Wim Carton  and Prof Jens Friis Lund Carbon Brief Its prominence in global pathways derived from technologically focused integrated assessment models has spurred a growing scientific […]

Columbia University’s new model for pricing carbon will help meet net-zero climate change goals

An article released today by researchers at Columbia University’s Center on Global Energy Policy in the journal Nature Climate Change introduces a new approach for pricing carbon — Near-term to Net Zero. As policymakers and advocates increasingly focus on net-zero emissions by midcentury, the Near-term to Net Zero approach is a method of setting carbon prices that could […]

Renewable Roundup: Making solar more sustainable (Through recycling and other means)

Sustainability means different things to different stakeholders. It can be mining and recycling of materials, and it can be the quite different question of a sustainable global economy that brings prosperity and other benefits to billions more people. It can be the question of profitability of investments in renewable energy, electric vehicles, sustainable agriculture, carbon-free […]

Renewable Roundup: How refrigeration figures in climate change action

Most of the attention on Global Warming quite rightly goes to renewable electricity and EVs. But we have to thank those who focus on the less glamorous parts of the problem. Refrigeration, including air conditioning, turns out to be another critical issue. By Mokurai Alternative Refrigerants — Drawdown Fluorinated gases are not the only refrigerants […]

Coronavirus set to cause largest ever annual fall in CO2 emissions

The global coronavirus pandemic continues to unfold at a staggering pace, decimating lives, livelihoods and the normal functioning of society, as well as interrupting energy demand and CO2 emissions. Previous Carbon Brief analysis showed that the crisis temporarily cut CO2 emissions in China by 25%, with emissions still below normal more than two months after the country entered lockdown.

Tackling a huge CO2 emitter: The cement industry

The cement industry is eager to shed the mantle of World’s Single Largest Industrial Carbon Emitter and it looks like it is ready to pass the torch to somebody else. A new industry-supported demonstration plant is taking shape in Europe, aimed at shaving out a large slice of carbon emissions from the cement-making pie. As […]
