Fascinating chart from International Energy Agency this... see how control / power over energy supply chains could evolve as we shift from oil + gas. UK among those who could miss out unless govt steps up efforts to attract investment...

To reach Net Zero by 2050, the Climate Change Committee reckon Britain will need to remove 35 million tonnes of carbon emissions from the atmosphere. That's the equivalent of taking 17 million cars off the road. Here's what I don't like about the CCC's plan.đź§µ

We vastly overestimate the importance of this data, given A) these are mainly state-owned entities largely indistinguishable from the state itself. B) mainly scope 3 when it comes to fossil fuels. C) these states have legitimate 'atmospheric claims' under progressive proposals

I somehow missed this from The Economist last week. This might end up being the biggest socioeconomic stories of our time: the rise of the rentiers. In the UK, inheritance is twice as important as a determinant of your wealth than it was for our parent's generation.

NEW ANALYSIS: Current UK running costs of heat pumps on standard tariff reach cost parity with gas boilers with average efficiency (SCoP 2.9). BUT: Highly efficient heat pumps + smart tariffs can more than halve heating costs. docs.google.com/spreadsheets/d…

Policymakers want more analysis, and modelers crave policy-relevance, leading to ever-increasing use of modeling in policymaking. Climate policies are prone to modeling overuse. Our article explains how to use models judiciously in climate policymaking. rdcu.be/ecSMX

Did you know that social cost of carbon is not a single concept but four distinct concepts that most everyone conflates? This book by Paul Kelleher an absolute must read for any economist interested in climate change. global.oup.com/academic/produ… academic.oup.com/book/59438

Net zero by 2050 is challenging but achievable. It is supported by the scientific community and backed by the independent Climate Change Committee as being not just necessary but feasible and cost-effective. We are already seeing the impact of climate change. From extreme

2/5 Instead, most of the carbon ends up in organic non-living reservoirs, both natural reservoirs (dead vegetation, soil organic carbon, sediments in lakes and wetlands) and human-made reservoirs (sediments in dams, landfills, and wood products).

3/5 One implication of the results is that the C stored from the current terrestrial sink (that removes over a quarter of all CO2 emissions from human activities) is more stable than we thought because it is less directly exposed to disturbances (wildfires, droughts, heatwaves).

This was a hard piece to write. China offers a hint of climate hope to many. But press conference rhetoric aside, a China coasting on its energy status quo remains, both quantitatively and in political economy terms, global decarbonization's big obstacle. foreignpolicy.com/2025/03/20/chi…

desalination, vertical farming, and yes, even sustainable jet fuel are all technologies that literally exist *today*, the constraint is that they are extremely energy intensive, and the premise of the book is that we need to build an abundant supply of clean energy
