Bill Kingdom says the battle against Covid provides lessons in how to cut consumption to ease global warming. Plus letters from Sue Dalley, David Hughes and Dave Hunter

In Adam Tooze’s article (By pushing for more oil production, the US is killing its climate pledges, 13 August), he surmised that economic activity and fossil fuel consumption are hardwired together. It may be more that economic activity and energy consumption are hardwired together – and thus the need to move to renewables or low-carbon energy sources. That must be part of the strategy, along with as yet unavailable technical solutions such as carbon capture.

However, we seem to tiptoe around the consumption part of any strategy. Lower consumption results in lower carbon emissions. The government has managed to exert strong influence over personal actions during the Covid pandemic using a myriad of three-word slogans. We need a similar push linked to consumption and climate change.
