Climate Change Leadership in Sweden? 80000 Sweden s Territorial Carbon Emissions (ktco 2 ) 70000 60000 50000 40000 30000 20000 Sweden s Climate Law No CO2 budget or annual emissions reductions in current form Does not include international transport emissions Includes other GHGs 10000 0 Klimatlagen med 6%/år Carbon Law OECD med 15%/år Global Carbon Law med 7%/år Ref: Naturvårdsverket (SMED), ), Rockström et al. 2017, Anderson et al. 2017
A Carbon Law for OECD? CEMUS Analysis: 1) Does not rely on highly speculative Negative Emission Technoligies NETs. 2) Takes some account of equity a slightly delayed timeframe for poorer nations and emissions from cement & deforestation not just their resp. 10-15% annual emissions reductions ½ of emissions ~ every 5 years.
Negative Emissions Technologies (NETs) + NATURAL uptake ~20GtCO 2 /year.~1/2 of what we emit Assumed that NETs will suck up 10-20GtCO 2 /year i.e. equivalent of up to another biosphere!
In Short A Swedish Carbon budget in line with Paris (CEMUS Carbon Law OECD): Very challenging emissions reductions for this generation Sweden s Climate Law (in its current form): Not equitable and very large risks are left for future generations Which one would our children and grandchildren choose?

Järfälla Municipality Energy and Climate Strategy 2017 Järfälla kan visa vägen och möjliggöra för andra regioner eller kommuner i både Sverige och andra länder att tidigarelägga och påskynda en snabb omställning till en fossilfri och hållbar framtid. För detta krävs konkreta åtgärder inom kommunens egen verksamhet och inom kommunens gränser. Miljöplanen presenterar olika förslag till åtgärder. I den kommande energi- och klimatplanen bör Järfälla konkretisera vilka åtgärder som ska prioriteras för att minska utsläppen med 10-15 procent per år, så att kommunen kan bidra med sin del, så att två graders-målet kan nås. (from Järfälla municipal board minutes 2017-08-16)
Main Results With current CO 2 emissions Paris 2 C will be surpassed ~17 years Sweden and Järfälla need ~15% CO 2 reductions p.a. for a fair chance of 2 C and support poorer countries in their development towards fossil free societies. Järfälla and Sweden can and should - lead the rapid transition to a fossil free future. The report can be downloaded at: www.cemus.uu.se
Regions as catalysts for rapid decarbonisation? A growing amount of municipalities, countries and multistate organisations are calculating CO2-budgets. Can regional policies, frameworks and strategies catalyse more ambitious national counterparts? How to engage citizens, organisations and businesses in the transition and also take consumption-based emissions into account? Mechanisms to support poorer countries and regions to develop fossil free socities? The report can be downloaded at: www.cemus.uu.se
