"It is critical to emphasise that existing forest should never be cut down to plant new trees." - Dr Bonnie Waring.

🌳 What do you value more, existing forests or new forests?
🌳 How much carbon is in a tree?
🌳 How much potential is there to plant new trees on earth?
🌳 Is planting trees the answer to climate change?

Q&A: Is planting trees the answer to climate change? | Imperial News | Imperial College London Grantham Institute’s new lecturer Dr Bonnie Waring answers your questions about reforestation.

Properly insulating UK homes and replacing fossil fuel boilers with heat pumps can help to alleviate fuel poverty, meet the UK’s longer-term net zero climate target, and support a just transition - but question marks still hang over the Government's plans, say Dr Aidan Rhodes and Dr Richard Hanna in a blog for Energy Futures Lab.

"It is in line with predictions of global warming going back decades now. What happens in the Arctic doesn't stay in the Arctic...The Arctic is warming at least twice as fast as the rest of the world. That means change is definitely on the way."

Professor Martin Siegert speaks to BBC News about the record-breaking heat in Siberia, and the wildfires it's causing.

A new Nature Energy study, by Imperial College London academics and colleagues, assesses the relative effectiveness of several carbon dioxide (CO2) mitigation routes by calculating the cost of mitigating CO2 emissions.

The key findings:

✅ Efficiency measures, such as improving building lighting, offer the most “energy-effective mitigation” and have a relatively large mitigation potential.

✅ Switching to renewable energy technologies are substantially more energy effective than carbon embedding or carbon removal approaches.

✅ Many yet-to-be deployed mitigation options have a relatively high energy cost compared with that of readily-available options.

Read the paper in full here:

Assessing the feasibility of carbon dioxide mitigation options in terms of energy usage Carbon emission reduction measures have widely differing energy consumptions that have not been systematically compared. Babacan et al. estimate comparable energy use per unit emission reduction of various emission reduction measures, from efficiency improvements to renewable electricity generation....

What do warmer summers mean for refrigeration in supermarkets? How can supermarkets continue to keep food fresh & reduce their carbon footprint?

This report, by Imperial College London and Sainsbury's, outlines how well-managed fridges can keep food cooler, be greener and cut costs.

"A warmer climate will mean refrigeration systems work harder and use more energy, however thorough monitoring and proactive maintenance regimes are a step in the right direction to solve these problems," said co-author Dr Salvador Acha.

Huge congratulations Shellworks, who took home to top prize of £30,000 in Imperial Enterprise Lab's largest entrepreneurial competition. Shellworks, who have been supported by our Cleantech Accelerator Programme, turn waste crustacean shells into biodegradable, compostable products, providing a plastic packaging alternative.

And a big round of applause for Treeconomy, who scooped the People's Prize! Treeconomy, who were supported by our 2019 ClimateLaunchpad competition, provide a one-stop-shop for landowners to earn money by planting trees and combating climate change.

Researchers at Imperial's Dyson School of Design Engineering have demonstrated how machine learning could help design lithium-ion batteries and fuel cells with better performance.

“Our team’s findings will help researchers from the energy community to design and manufacture optimised electrodes for improved cell performance. It’s an exciting time for both the energy storage and machine learning communities, so we’re delighted to be exploring the interface of these two disciplines," said Dr Sam Cooper.

"A coronavirus recovery plan that priorities climate action can reinvigorate the economy and create a resilient society – and local authorities are best placed to deliver this."

In our latest blog, Dr Neil Jennings explains why the government must accelerate a green recovery at the local level, and why the Grantham Institute supports 'A blueprint for accelerating climate action and a green recovery at the local level'.
