What we learned this week

New Zealand has declared a climate emergency and that the government will try to get its own emissions to net zero by 2025. (It got less coverage, but Japan declared a climate emergency a couple of weeks ago too.) These are symbolic of course, but they are also a powerful statement of intent.

How adding seaweed to cattle feed can reduce emissions. The easiest way to reduce beef emissions is to reduce beef consumption of course, but this is useful too.

I learn from the Spokesmen Cycling Podcast that cargo bikes move 3.5 kph faster than vans in central London, making them a faster way to make local deliveries as well as a cleaner one.

“Rich countries have disproportionate influence when it comes to setting the rules of international trade and finance” writes Jason Hickel, highlighting the colonial influences in the IMF and World Bank.

Have you seen the front cover of The Economist this week? ‘Making coal history’ is the cover story.

I gave a talk last week on climate, race and privilege, for my friends at Christian Climate Action. With apologies for the quality of the Zoom recording, here it is. If people find this useful, I might try and record a better version.

What we learned this week

On Thursday evening I’m talking about my book Climate Change is Racist with Esther Stanford-Xosei, an event with XR Southwark and online. Details here if you’d like to join. For educators thinking about how climate change is taught, have a look at the recorded talks and other resources from the Climate Education Summit. Not new […]

Hydrogen and the future of heating

As Britain aims to reach zero carbon by 2050, there are a number of big priorities on the to-do list. The most high profile is to switch all electricity production away from fossil fuels. Another is to eliminate petrol and diesel from the transport system. Then there’s the third big ticket item: deliver low carbon […]

Guest post: 5 reasons to talk about adaptation

By Dr. Morgan Phillips – Co-Director, The Glacier Trust Many in the environmental and climate movement remain reluctant to talk about climate change adaptation. This is slowly changing, but if you are still sceptical, it pays to remember that the adaptation story is not, and does not have to be, in opposition to the mitigation […]

  1. Yes indeed on e-bikes point: it reminds me of this: https://www.eav.solutions
    I saw an independent write up(s) of these people; I think major logisics firms are seriously interested because they have major advantages for ‘last mile’ delivery, which is the area logicstics firms are finding hard to crack (both economics and sustainability I think). Our ‘pipe dream’ for Chipping Norton is to have a ‘community last mile delivery depot’ run as a COMMUNITY social enterprise, using bikes like these.
