지구온난화를 막고자 전 세계가 온실가스를 줄이는 데 합의한 역사적인 기후변화 협정이 12일(현지시간) 체결됐다.

유엔 기후변화협약 당사국총회(COP21) 195개 협약 당사국은 이날 파리 인근 르부르제 전시장에서 열린 총회 본회의에서 2020년 이후 새로운 기후변화 체제 수립을 위한 최종 합의문을 채택했다.

총회 의장인 로랑 파비위스 프랑스 외무장관은 "총회장 반응이 긍정적이다. 반대 목소리가 없다"면서 "파리 기후협정이 채택됐다"고 선언했다.

파비위스 장관이 협정 통과를 선언하면서 의사봉을 두드리자 각국 대표들은 큰 박수를 보내면서 자리에서 일어나 서로 껴안고 기뻐했다.

'파리 협정'은 선진국만 온실가스 감축 의무가 있었던 1997년 교토 의정서와 달리 195개 당사국 모두 지켜야 하는 첫 세계적 기후 합의로 18년만에 새로운 기후체제 출범을 알리는 협약이다.

협정 일부는 구속력이 있으나 일부는 당사국의 자발적인 참여에 달렸다. 온실 가스 감축 계획안을 제출하고 정기적으로 약속 이행 검토를 받는 것 등은 구속력이 있으나 당사국이 정한 감축 목표 자체는 구속력이 없다.

반기문 유엔 사무총장은 "역사가 오늘을 기억할 것이다"면서 "파리 협정은 사람과 지구에 기념비적인 승리다"라고 말했다.

버락 오바마 미국 대통령은 트위터에 "미국의 지도력 덕택에 세계 대부분 국가가 파리 협정에 서명했다"면서 "엄청난 성공이다"라고 협정 체결을 환영했다.

31페이지 분량의 파리 협정 최종 합의문을 보면 당사국들은 새 기후변화 체제의 장기 목표로 "지구 평균온도의 상승폭을 산업화 이전과 비교해 섭씨 2℃보다 '훨씬 작게' 제한하며 섭씨 1.5℃까지 제한하는데 노력한다"고 적혀 있다.

이는 지구 온난화로 인한 해수면 상승으로 어려움을 겪는 도서 국가나 기후변화 취약 국가들이 요구해 온 사항이다. 현재 지구 온도는 이미 산업화 이전보다 1℃가량 상승한 상태다.

온도 상승폭을 제한하기 위해 한국을 포함해 187개국은 이번 총회를 앞두고 2025년 또는 2030년까지 온실가스를 얼마나 줄일 것인지 감축목표(기여방안·INDC)를 유엔에 전달했다.

그러나 당사국이 제출한 INDC로는 온도를 섭씨 2.7℃로 제한하는데 그칠 것으로 추정됐다.

또 지구의 온실가스 총 배출량이 감축 추세로 돌아서는 시점을 최대한 앞당기고 감축세에 접어들면 그 속도를 높이기로 했다. 개발도상국은 선진국보다 이 과정이 더 오래 걸릴 것이라는 차이를 인정했다.

당사국들은 합의문에서 금세기 후반기에는 인간의 온실 가스 배출량과 지구가 이를 흡수하는 능력이 균형을 이루도록 촉구했다.

온실가스를 좀 더 오랜 기간 배출해온 선진국이 더 많은 책임을 지고 개도국의 기후변화 대처를 지원하는 내용도 합의문에 포함됐다.

선진국은 2020년부터 개도국의 기후변화 대처 사업에 매년 최소 1천억 달러(약 118조1천500억 원)를 지원하기로 했다.

이 협정은 구속력이 있으며 2023년부터 5년마다 당사국이 탄소 감축 약속을 지키는지 검토하기로 했다.

지난달 30일 개막한 이번 총회에서 195개국 대표들은 교토의정서를 대체할 새로운 합의문을 마련하고자 논의했다.

앞서 1997년 채택된 교토 의정서는 선진국에만 온실가스 감축 의무를 지웠지만 파리 협정은 선진국과 개도국 모두 책임을 분담하기로 하면서 전 세계가 기후 재앙을 막는데 동참하게 됐다.

이날 합의에 대해 일부 환경 운동가들은 지구를 보호하기 위해 충분하지 않다면서 파리 에펠탑 주변 등지에서 시위를 벌였다.

애초 이 총회는 전날인 11일 끝날 예정이었으나 협상 참가국 간 견해차 때문에 이날까지 회의 기간이 하루 연장됐다. (연합)

Historic pact to slow global warming is celebrated in Paris

Nearly 200 nations adopted the first global pact to fight climate change on Saturday, calling on the world to collectively cut and then eliminate greenhouse gas pollution but imposing no sanctions on countries that don’t.

The “Paris agreement” aims to keep global temperatures from rising another degree Celsius (1.8 Fahrenheit) between now and 2100, a key demand of poor countries ravaged by rising sea levels and other effects of climate change.

Loud applause erupted in the conference hall after French Foreign Minister Laurent Fabius gaveled the agreement. Some delegates wept, others embraced.

“It’s a victory for all of the planet and for future generations,” U.S. Secretary of State John Kerry said, adding that the pact will “prevent the worst most devastating consequences of climate change from ever happening.”

Brazilian Environment Minister Izabella Teixeira added: “Today, we’ve proven that it’s possible for every country to come together, hand in hand, to do its part to fight climate change.”

In the pact, the countries pledge to limit the amount of greenhouse gases emitted by human activity to the levels that trees, soil and oceans can absorb naturally, beginning at some point between 2050 and 2100.

In practical terms, achieving that goal means the world would have to stop emitting greenhouse gases _ most of which come from the burning of oil, coal and gas for energy _ altogether in the next half-century, scientists said. That’s because the less we pollute, the less pollution nature absorbs.

Achieving such a reduction in emissions would involve a complete transformation of how people get energy, and many activists worry that despite the pledges, countries are not ready to make such profound, costly changes.

The deal now needs to be ratified by individual governments _ at least 55 countries representing at least 55 percent of global emissions _ before taking effect. It is the first pact to ask all countries to join the fight against global warming, representing a sea change in U.N. talks that previously required only wealthy nations to reduce their emissions.

“History will remember this day,” U.N. Secretary General Ban Ki-moon said. “The Paris agreement on climate change is a monumental success for the planet and its people.”

Speaking from Washington, President Barack Obama said the climate agreement offers “the best chance to save the one planet we have.”

The deal commits countries to keeping the rise in global temperatures by the year 2100 compared with pre-industrial times “well below” 2 degrees Celsius (3.6 degrees Fahrenheit), and says they will “endeavor to limit” them even more, to 1.5 degrees Celsius. The world has already warmed by about 1 degree Celsius since pre-industrial times.

Ben Strauss, a sea level researcher at Climate Central, said limiting warming to 1.5 degrees instead of 2 degrees could potentially cut in half the projected 280 million people whose houses will eventually be submerged by rising seas.

More than 180 countries have ready presented plans to limit greenhouse gas emissions_ a breakthrough in itself after years of stalemate. But those pledges are not enough to achieve the goals in the accord, meaning countries will need to cut much more to meet the goal.

“We’ve agreed to what we ought to be doing, but no one yet has agreed to go do it,” said Dennis Clare, a negotiator for the Federated States of Micronesia. “It’s a whole lot of pomp, given the circumstances.”

The agreement sets a goal of getting global greenhouse gas emissions to start falling “as soon as possible”; they have been generally rising since the industrial revolution.

It says wealthy nations should continue to provide financial support for poor nations to cope with climate change and encourages other countries to pitch in on a voluntary basis. That reflects Western attempts to expand the donor base to include advanced developing countries such as China.

In a victory for small island nations, the agreement includes a section highlighting the losses they expect to incur from climate-related disasters that it’s too late to adapt to. However, a footnote specifies that it “does not involve or provide any basis for any liability or compensation” _ a key U.S. demand because it would let the Obama administration sign on to the deal without going through the Republican-led Senate.

The adoption of the agreement was held up for nearly two hours as the United States pressed successfully to change the wording on emissions targets from saying developed countries “shall” commit to reducing emissions to they “should.” Experts said that means the deal probably won’t need U.S. congressional approval.

Nicaragua said it would not support the pact. Its envoy, Paul Oquist, said the agreement does not go far enough to cut global warming and help the poor countries affected by it.

Nicaragua is one of eight participating countries that haven’t submitted emissions targets, after Venezuelan envoy Claudia Salerno said her country _ which had been holding out _ liked the agreement and had submitted its pledge.

Thousands of protesters demonstrated across Paris, saying the accord is too weak to save the planet. People held hands beneath the Eiffel Tower and stretched a two-kilometer-long (1.2-mile-long) banner from the Arc de Triomphe to the business district La Defense.

Kumi Naidoo of Greenpeace said the accord is a good start but isn’t enough.

“Today the human race has joined in a common cause, but it’s what happens after this conference that really matters,” he said. “This deal alone won’t dig us out the hole we’re in, but it makes the sides less steep.”

The accord does represent a breakthrough in climate negotiations. The U.N. has been working for more than two decades to persuade governments to work together to reduce the man-made emissions that scientists say are warming the planet.

The previous emissions treaty, the 1997 Kyoto Protocol, included only rich countries and the U.S. never signed on. The last climate summit, in Copenhagen in 2009, ended in failure when countries couldn’t agree on a binding emissions pact.

The talks were initially scheduled to end Friday but ran over as Western powers, tiny Pacific island nations and everyone in between haggled over wording.

The main dispute centered over how to anchor the climate targets in a binding international pact, with China and other major developing countries insisting on different rules for rich and poor nations. The agreement struck a middle ground, removing a strict firewall between rich and poor nations and saying that expectations on countries to take climate action should grow as their capabilities evolve. It does not require them to do so.

Some scientists who had criticized earlier drafts as unrealistic praised the final pact for including language that essentially means the world will have to all but stop polluting with greenhouse gases by 2070 to reach the 2-degree goal, or by 2050 to reach the 1.5-degree goal.

That’s because when emissions fall, nature compensates by absorbing less carbon dioxide _ and can even release old pollution once there’s less of it in the air, said Princeton University’s Michael Oppenheimer. Forests, oceans and soil currently absorb about half the world’s man-made carbon dioxide emissions.

“It means that in the end, you have to phase out carbon dioxide,” said John Schellnhuber, director of the Potsdam Institute for Climate Impact Research in Germany.

In addition to the cuts in emissions, the goal could be reached in part by increasing how much carbon dioxide is sucked out of the air by planting forests or with futuristic technology, Oppenheimer said, but added such technology would be expensive.

French President Francois Hollande welcomed the world to a “low carbon age,” saying France is ready to cut emissions even further and increase aid to poor countries that are affected. He challenged all nations to do more.

“The 12th of December, 2015, will remain a great date for the planet,” Hollande declared. “In Paris, there have been many revolutions over the centuries. Today it is the most beautiful and the most peaceful revolution that has just been accomplished _ a revolution for climate change.” (AP)
