Focus on covid and emissions + need for strong decarbonisation in economic recoveries; growing list of countries committing to net-zero.
Our chapter focuses on lifestyle change: the need for this, where and how. A thread⊠1/

Our chapter focuses on lifestyle change: the need for this, where and how. A thread⊠1/
First, the basics: lifestyle change is necessary for GHG emissions reduction.
Approx two-thirds emissions linked to household activities. Tech and energy supply alone is not enough without our involvement in move towards low-carbon society. 2/

Lifestyle change means changing the systemic conditions that shape how we live; this is very much not all down to individuals!
But those conditions wonât change without public support, activism, effort. We need to be active participants in change, not just âconsumersâ. 3/

How we live needs to change. But not all lifestyles are equal.
Co-authors @tim_e_gore and @diana_nbd show how horrendous is the disparity within and between countries. Total global emissions of top 1% people are TWICE that of lowest-emitting 50%. 4/

In order to get to emissions in line with 1.5 °C, need to reduce per capita emissions to ~2 to 2.5 CO2 by 2030.
The poorest 50% of people globally could increase by factor of ~3 and still meet this; the richest 1% need to reduce current emissions by a factor of 30

Vast differences b/w peoplesâ emissions shown through total/aviation carbon footprints â again @diana_nbd analysis.
In the EU, top 1% ppl's emissions from flying ~23tonnes, middle 40% ~0.1tonnes annually. Not globally â in Europe! (Circles to scale, my Fig not @UNEP) 6/

Lifestyle change is needed across different sectors: food, transport, residential. Co-authors @diana_nbd @nicolejvdb show options to avoid (do less of it), shift (change how you do it) and improve (do same thing but better) can contribute. 7/
Lifestyle change for emissions reduction has other benefits: cleaner air, healthier diets, job creation â as also demonstrated by recent @LancetCountdown report 8/ https://twitter.com/LancetCountdown/status/1334287003005882369
There are practical examples around the world showing how we can lead more sustainable lives: some push, some pull.
Lifestyle change can be driven by policy, economics and infrastructure; by cultural shifts and civil society; at behavioural and inter-personal level. 9/

The @UNEP lifestyle chapter separately summarises approaches to achieve low-carbon mobility, diets, homes â we draw on cases where this is happening, and draw attention to ways this *could* happen. 10/
As co-author @ilonamotto has shown, social conventions can change quickly via tipping points: a major reason for ppl to participate in societal transformation for climate change. Thanks @steviedubyu for insights here too. 11/
Lifestyle change for emissions reduction means changing social practices; as co-author @ClaireHoolohan points out this means changing the patterns of daily life, physical set-ups that enable or constrain how we live, and the meanings we attach to our ways of life. 12/
Much of how we live on a day-to-day basis is grounded in habit and routine; co-author @lwhitmarsh explains we are most susceptible to influence during âmoments of changeâ, whether at personal level or in context of larger-scale disruption. 13/
Low-carbon societies are poorly aligned with current economic/political systems & collide w/ vested interests in many places, as co-author @lewisakenji points out.
Achieving low-carbon lifestyles will require deep-rooted changes to how our societies are structured 14/

Co-author Kate Power of @KRFoundation draws attention to ways reducing gender and income inequality and improving wellbeing, can also reduce emissions; revaluing care work and shorter working week could play a part in this. 15/
Communication and engagement about lifestyle change is essential, as co-author @AJCorner points out. We need to find ways to do this that emphasize the dynamic and complex relationship between systems and behaviour. 16/ https://climateoutreach.org/bridging-gap-role-of-low-carbon-lifestyles/
To conclude, the participation of people and groups across civil society, as well as government and industry, is needed to ensure lifestyle change happens in a way that preserves peopleâs well-being while achieving substantial and rapid cuts in GHG emissions. 17/
Itâs been excellent & thought-provoking to work with brilliant co-lead-authors @susiewang & Radhika Khosla of Oxford @OxfordCooling to bring together our @UNEP chapter on lifestyle change, in collaboration with the nine amazing co-authors mentioned

In 1 tweet our @UNEP chapter concludes
-Lifestyle change needed for climate action, but
-Not everyoneâs footprint is equal
-Change needed at all scales: system to individual
-Change is achievable, itâs happening, but
-It wonât be easy and
-We need to be active participants
