Commercial and domestic gas boilers are responsible for around 16% of London's NOx emissions (data from 2016). Energy efficiency measures can improve air quality and reduce your energy bills. Read about the things that you can change at home.

In historic terms, UK air quality is much better than it was back in the days when everyone had a coal fire leading to terrible smogs. In 1952, The Great Smog of London led to an estimated 12,000 people dying. Ultimately, the event led to the Clean Air Act of 1956. Even so, there was another smog reaching across much of the country during the big freeze winter of 1962. Looking at the graph we can see how pollution has declined.

Hi everyone, following on from Morgan, my name is Armelle and I am another member of CREW! I have just finished my studies in Geography with Economics and, outside of CREW, my interests lie in green finance, ESG investing and the global energy transition. I started with CREW at the end of 2019 and initially joined as an Energy Advisor, to be a part of the work CREW does to alleviate fuel poverty within our local community.

Hi, my name is Morgan da Silva and I am a member of CREW. My background stems from the desire to see everyone have access to electricity around the world. In some places, renewable energy can provide clean and accessible electricity where governments cannot afford to extend the grid. I began with a development project in Nicaragua that operated on this principle and installed pico solar systems in rural areas.

Nine energy suppliers have gone to the wall and more are likely to follow in the coming weeks and months, under pressure from spiralling gas prices. We have heard the reasons for these price rises: last year's cold winter, a lack of storage (especially in the UK), interconnector issues and the global recovery post pandemic.
