Vivid cli­mate change poli­cies

Franklin County News - - OUT & ABOUT -

‘‘Such a re­duc­tion in emis­sions is chal­leng­ing, made more so when we con­sider that de­vel­op­ing coun­tries will ex­pect to be able to achieve the same stan­dard of liv­ing as we en­joy.’’

A re­liance on yet-to-be­de­vel­oped tech to solve our prob­lems is a risky strat­egy.

The third sce­nario re­lies on even more ex­ten­sive forestry plant­ings but avoids the tech­nol­ogy trap.

To me, these sce­nar­ios miss two low hang­ing fruit that are ac­tion­able today, inexpensive and low-risk.

One is to con­vert in­dus­tries us­ing fos­sil fu­els for process heat, to us­ing biomass-based heat plant.

The coun­try has sig­nif­i­cant woody biomass avail­able to start that tran­si­tion today and suf­fi­cient land avail­able for us to meet fu­ture de­mand.

The other is around us­ing biochar as a car­bon se­ques­tra­tion tech­nol­ogy.

The ease of ap­ply­ing this tech­nol­ogy was demon­strated at last week’s Charcoal Fire event in Pukekohe.

Re­mov­ing at­mo­spheric car­bon is a key solution of­fered in an­other vivid re­port last month.

A group of Euro­pean sci­en­tists’ pub­lished ‘‘A roadmap for rapid de­car­boniza­tion’’ in Sci­ence Mag­a­zine.

Their sim­ple, al­beit daunt­ing, road map also calls for a cut to global CO2 emis­sions - by half for each of the next three decades.

Such a re­duc­tion in emis­sions is chal­leng­ing, made more so when we con­sider that de­vel­op­ing coun­tries will ex­pect to be able to achieve the same stan­dard of liv­ing as we en­joy.

That re­quires in­creas­ing en­ergy de­mand, not re­duc­ing it.

Which means that de­vel­oped coun­tries will have to shoul­der all of the global emis­sions re­duc­tion tar­get.

So yes, our par­lia­men­tar­i­ans do have to de­liver a cli­mate pol­icy, but their task will not be easy.
