Apr 19, 2021 · April 19, 2021. Energy.gov. How We’re Moving to Net-Zero by 2050. There’s no greater challenge facing our nation and our planet than the climate crisis—and the writing on the wall is that in order to avoid its worst effects, we need to do everything we can to achieve President Biden’s goal of net-zero carbon emissions by 2050.
Mar 31, 2021 · A net zero climate-resilient future – science, technology and the solutions for change. This Statement has been created by the Science Academies of the Group of Seven (G7) nations. It represents the Academies’ view on the need for the G7 countries to anticipate the risks associated with climate change, face the transition that this requires ...
May 18, 2021 · The number of countries announcing pledges to achieve net zero emissions over the coming decades continues to grow. But the pledges by governments to date – even if fully achieved – fall well short of what is required to bring global energy-related carbon dioxide emissions to net zero by 2050 and give the world an even chance of limiting the global temperature rise to 1.5 °C.

May 21, 2021 · The U.N. climate science panel has said that man-made carbon dioxide emissions need to fall by about 45% by 2030, from 2010 levels, and reach "net zero" by mid-century to give the world a good chance of limiting warming to 1.5C and avoiding the worst impacts of climate change. Under the 2015 Paris Agreement, nearly 200 countries said they would ...

Creating models that simulate the Earth’s climate system has been one of the great scientific achievements of the last half-century. Achieving the step-change in resolution and computing capacity to fully understand global impacts of climate change at kilometre-scale will require international collaboration to harness the power of exascale computin...
Much is now understood about the Earth’s carbon cycle – how the land and ocean act as sinks to absorb more than half of the carbon dioxide emitted by human activity. However, deeper understanding is needed, – particularly of whether the sinks will continue to sequester carbon dioxide at historical levels as they are themselves afected by climate ...
Lithium-ion batteries (LIBs) have been a scientific success story, now deployed in millions of vehicles worldwide. Advanced LIBs followed by a new generation of battery technologies could deliver faster charging and longer ranges, lower costs and decarbonise the electricity grid and power heavy transport.
As well as heat, hydrogen has a wide range of potential low-carbon roles in transport, power and storage that require demonstration. With the right investment and infrastructure, hydrogen could be scaled up to decarbonise sectors less suited to electrification, such as heat for industry, while ammonia, derived from hydrogen, is a leading option for...
While land use change and farming generates emissions, land-based projects that prevent degradation of forests, grasslands, peatlands and other ecosystems can contribute to net zero and generate benefits for local communities. The global food system accounts for around one-third of all GHG emissions, a footprint that can be reduced by more sustai...
Policy and economics play a major role in the deployment of the net zero tools provided by science and technology. Analysis informed in association with the British Academy shows how ‘Building back better’ from COVID-19 can ‘kick’ or ‘shift’ economies towards long-term incentives for emissions reduction, that can also support jobs, wellbeing, and ...

May 16, 2023 · Climate and Economic Resilience in a Changing World. Climate policy making today demands balancing the need for immediate, accelerated climate action with essential responses to punctual crises such as the COVID-19 pandemic and Russia’s war of aggression in Ukraine. Meeting this challenge requires a new approach centred on systemic resilience ...
Climate change is a real and rapidly increasing danger to people and the planet. The world is already experiencing the impacts of a dangerous rise in global temperatures, with significant effects on ecosystems, socio-economic systems, and human welfare. Science tells us we must act now and continue to act into the future to deliver net zero ...
