The report estimates premature mortality, years of life lost and asthma cases in the EU and UK attributable to indoor nitrogen dioxide from gas cooking. Using modelling of indoor exposures and concentration–response functions, it quantifies associated economic costs and highlights potential health gains from transitioning to cleaner cooking energy

The report outlines a universal basic services approach to UK transport, highlighting inequitable access, high emissions, and car dependence. It assesses current government reforms and recommends long-term, publicly oriented investment to expand affordable, integrated, low-carbon mobility, prioritising public transport and active travel within environmental limits.
