Detailed carbon emissions data is a vital weaponinthefightagainstclimatechange.Anewstudyhas,forthefirsttime,enabled79ofthe world’s leading cities to understand how their impact on climate change extends beyond theirboundaries.

Thestudy,conductedbyArup,UniversityofLeeds,UniversityofNewSouthWalesandC40, calculated each city’s consumption-basedgreenhousegasemissions.TheCityConsumption-Based Emissions Inventories takeintoaccountemissionsfromtheproductsandservicescitiesconsume,suchasfoodorclothingmadeelsewhere.

Thisapproachrevealedthatconsumptionemissionsfromthe79citiesaresignificant,makingup7%ofglobalannualemissions.Infact,63ofthe79C40citieshavemoreemissionsfromconsumptionthanfromproduction–thetruescaleoftheirimpactis under-represented using more common reportingmethodologies.

While cutting carbon emissions can help limit global temperature rise, the built environment also needs to adapt to changes that are alreadyinevitable.InLondon,apioneeringdevelopment is demonstrating that sustainability and adaptability don’t mean compromising on thequalityofinternalenvironments–andcanactuallysavemoney.

Derwent London’s White Collar Factory is a 16-storeytowerwitha150mrooftoprunningtrackandterrace.It’samodelforanewtypeofofficebuildingofferingusersgreaterflexibility,morechoiceovertheirworkingenvironment,andcomfortable,productivespaces.

We spent 10 years shaping the concept, guided byfivekeyprinciples:highceilings,athermal-massstructure,asimplepassivefaçade,flexiblefloorplatesand‘smart’servicing.Theresult:abuildingthatbreaksfreefrommechanicalair conditioning and controls its environment passively.

At its heart, in-slab cooling uses the thermal massoftheconcretecoretoabsorbheatenergy–madepossiblebyafaçadetunedtoits orientation that passively limits solar gains

White Collar Factory uses 33% less energy than building regulations require and has a 25%smallercarbonfootprint.It’salsooneofonly seven projects to achieve both BREEAM Outstanding and LEED Platinum, and is rated EPC‘A’andWiredScorePlatinum.
