Building on the SAMHE project, we have developed a web-based tool to estimate the costs and benefits (in terms of both energy use and classroom air quality) of installing HEPA filter units in individual school settings. We co-designed the tool with prospective users including schools, local authorities and the Department for Education. The CHEPA (Classroom HEPA) tool is now free and available to all.

Inkomstnivå, bostadsort och tillgång till alternativ till egen bil påverkar hur människor kommer att uppleva omställningen. Särskilt äldre och unga boende i områden med låg befolkningstäthet uttrycker oro när det gäller rättvisa och jämlikhet i övergången till fossilfria transporter.

Så mycket som 40 procent av Sveriges befolkning skulle kunna löpa en relativt hög risk att drabbas negativt av planerna på en övergång till ett fossilfritt samhälle om de inte får stöd av kompletterande åtgärder som hjälper till att säkerställa en rättvis omställning.

Styrmedel och strategier för att åstadkomma den fossilfria omställningen måste anpassas efter och ta hänsyn till olika gruppers förutsättningar att kunna hantera omställningen, mot bakgrund av socioekonomiska och geografiska faktorer, och skillnader i klimatavtryck.

Det finns lösningar som kan användas för att stödja dem som påverkas negativt av omställningen till ett fossilfritt transportsystem och har svårare att anpassa sig.

Income levels, place of residence, and access to alternatives to cars affect how people will experience the low-carbon transport transition. Older and young people living in low-density areas in particular have equity and fairness concerns about the transition.

As much as 40% of Sweden’s population could be at a relatively high risk of being adversely affected by transition plans if they do not receive supportive complementary measures to ensure a just transition.

Policy for transitions to a low-carbon society need to be tailored to different groups in society to better take into consideration differences in climate footprints and the ability of different groups to cope, according to socioeconomic and geographic factors.

Solutions are available today to support those that would be negatively affected by the transition and would have a harder time adjusting.
