COP27: Zelenskiy says climate policy impossible without peace

STORY: "There can be no effective climate policy without the peace," he said, highlighting the impact of Russia's invasion of Ukraine on global energy supplies, food prices and Ukraine's forests.

"This Russian war has brought about an energy crisis that has forced dozens of countries to resume coal-fired power generation in order to lower energy prices for their people ... to lower prices that are shockingly rising due to deliberate Russian actions," Zelenskiy said.

Ukraine is hosting an exhibition space this year for the first time at a U.N. climate conference in Sharm el-Sheikh, Egypt. But unlike the other booths at COP27 that are festooned in colourful logos, flags and greenery, Ukraine's stood out for its bleakness - covered in gravely grey to symbolise the war at home.
