For thir­ty years, the world has con­vened at COP meet­ings to address cli­mate change. These year­ly gath­er­ings have shaped hopes, revealed dis­ap­point­ments, and chal­lenged our col­lec­tive hon­esty. But as I explain in Green for Life, true cli­mate lead­er­ship only hap­pens when we stop just act­ing and start being hon­est. That truth is this: if thir­ty years of nego­ti­a­tions haven’t solved the cri­sis, then the cri­sis isn’t about tech­ni­cal chal­lenges. It’s about glob­al will.

Cli­mate change has nev­er been an unsolv­able puz­zle. The sci­ence has spo­ken clear­ly for decades. Com­mu­ni­ties world­wide have endured the con­se­quences even longer. What has been lack­ing is sin­cer­i­ty. Because of this, we now face a cli­mate real­i­ty that affects every life: harsh­er droughts across Africa, inten­si­fy­ing cyclones in the Indi­an Ocean, heat waves push­ing cities to the edge, and floods sweep­ing through regions that once had pre­dictable sea­sons. We are grow­ing numb to catastrophe.

COP30 arrives at a moment the world can no longer post­pone. Its host city, Belém, stands at the entrance to the Ama­zon, a place that rep­re­sents both the planet’s lungs and its con­tra­dic­tions. We cel­e­brate forests in speech­es, yet we allow new oil fields to be licensed with­in their shad­ows. We praise indige­nous wis­dom yet extract resources beneath the feet of the very com­mu­ni­ties that pro­tect nature best. We dis­cuss cli­mate jus­tice, yet we offer vul­ner­a­ble nations loans instead of relief.

If COP30 is to have any impact, it must iden­ti­fy these contradictions.

The first truth is that wealthy nations have not ful­filled their com­mit­ments. The long-promised $100 bil­lion annu­al­ly remains unre­li­able, incon­sis­tent, or is deliv­ered as debt dis­guised as sup­port. Even the lat­est glob­al finance goal, announced with much cel­e­bra­tion, falls sig­nif­i­cant­ly short of what cred­i­ble analy­sis con­sid­ers enough. A world fac­ing a tril­lion-dol­lar cli­mate bill can­not rely on polit­i­cal symbolism.

The sec­ond truth is that fos­sil fuels still dom­i­nate glob­al pol­i­tics. Even after promis­es to move away from them, invest­ments in new oil and gas projects con­tin­ue world­wide. As long as fos­sil fuel expan­sion is seen as nor­mal, cli­mate goals will stay just words.

The third truth is that Africa also needs to address its inter­nal chal­lenges. When cli­mate resources are mis­han­dled or divert­ed, we under­mine our moral author­i­ty. Hav­ing integri­ty at home enhances our influ­ence abroad.

How­ev­er, despite these real­i­ties, Africa remains one of the world’s most promis­ing solu­tions for tack­ling cli­mate change. Our con­ti­nent holds most of the untapped arable land, has incred­i­ble renew­able ener­gy poten­tial, con­tains essen­tial min­er­als for clean tech­nolo­gies, and fea­tures nat­ur­al ecosys­tems that store large amounts of car­bon. The Con­go Basin, for exam­ple, helps sta­bi­lize glob­al cli­mate pat­terns far more than most real­ize. Beyond nature, our young pop­u­la­tion, full of ener­gy, cre­ativ­i­ty, and inno­va­tion, rep­re­sents the great­est oppor­tu­ni­ty for a clean and pros­per­ous future.

If the world is com­mit­ted to cli­mate progress, Africa must shift from the mar­gins to the forefront.

COP30 must there­fore revise expec­ta­tions in four key ways.

First, cli­mate finance must acknowl­edge sci­en­tif­ic urgency. Grants and high­ly con­ces­sion­al fund­ing should replace debt-heavy sys­tems that penal­ize vul­ner­a­ble nations for a prob­lem they did not create.

Sec­ond, Africa must be empow­ered to devel­op envi­ron­men­tal­ly friend­ly indus­tries by uti­liz­ing renew­able ener­gy, new tech­nolo­gies, and equi­table val­ue chains.

Third, the Loss and Dam­age Fund must final­ly turn from an idea into action, pro­vid­ing tan­gi­ble relief to fam­i­lies and nations already suf­fer­ing from the con­se­quences of glob­al inaction.

Fourth, glob­al forests, from the Ama­zon to the Con­go Basin, must be acknowl­edged as essen­tial cli­mate infra­struc­ture, deserv­ing sta­ble, long-term inter­na­tion­al support.

COP30 can’t be just anoth­er event full of fan­cy speech­es. The world has got­ten good at mak­ing dec­la­ra­tions, but it has­n’t mas­tered the courage to act on them. Yet, courage is what the moment calls for.

As I men­tioned in Green for Life, when Africa speaks with one voice, firm, clear, and prin­ci­pled, the world lis­tens. In Belém, we must speak bold­ly. Not as sup­pli­cants, but as stew­ards. Not as vic­tims, but as part­ners. Not as a con­ti­nent wait­ing for per­mis­sion, but as a con­ti­nent hold­ing a key to glob­al survival.

His­to­ry will judge COP30 not by its words but by its actions.

If Belém marks the moment when the world final­ly choos­es truth over per­for­mance, then COP30 will be remem­bered as a turn­ing point.

If it does­n’t, his­to­ry will remem­ber those who stayed silent at the edge of dis­as­ter. Think green, act green.
