Sus­tain­able Devel­op­ment Goals (SDGs)


PLAN B is a civ­il soci­ety ini­tia­tive in the process of being found­ed as an asso­ci­a­tion. Our goal is a cli­mate-neu­tral and social­ly just Berlin 2030, in line with the vision of a donut econ­o­my and imple­ment­ing the Paris Agree­ment at the munic­i­pal lev­el. We know how to achieve this goal: by mea­sur­ably reduc­ing our emis­sions and ener­gy costs, insu­lat­ing our homes cheap­ly and quick­ly, calm­ing traf­fic in our neigh­bor­hoods, putting ener­gy pro­duc­tion in cit­i­zen hands, mak­ing good region­al plant-based food afford­able, green­ing rooftops, pro­tect­ing and regen­er­at­ing water and urban nature, and using few­er resources because we use, exchange, share, and recy­cle them smarter.


We offer dif­fer­ent projects to help to reach our goal: Our first pilot is the Ger­man adap­ta­tion of the US-Amer­i­can Neigh­bor­hood Orga­niz­ing Pro­gram “Cool Blocks” as part of the Cool City Ini­tia­tive, which is cur­rent­ly under­way with the active par­tic­i­pa­tion of 8 teams orga­niz­ing 50 house­holds in Berlin. Oth­er than that we are pro­mot­ing bal­cony solar pan­els as an entry point towards cit­i­zen ener­gy pro­duc­tion and have con­cep­tu­al­ized and lob­bied for BERTA (work­ing title) — imple­men­ta­tion-ori­ent­ed trans­for­ma­tion alliances that are sup­port­ed by Berlin’s urban soci­ety, involv­ing all sen­ate admin­is­tra­tions and enabling an accel­er­a­tion of the upcom­ing trans­for­ma­tion mea­sures
