What The Ozone Layer Teaches Us About Climate Action

06 APR, 2021

when it comes to the Paris Agreement and climate action; namely that when individuals change their behaviour by consuming differently they can drive industries to change, as those industries are then caught between a ‘greening’ consumer demand and international and governmental policies focusing on climate action.

Back in the 1980s, everyone was talking about the hole in the ozone layer, so what happened, and what can the international agreement to ban CFCs teach us about the importance of multilateral cooperation when it comes to climate action?

What exactly is the ozone layer?

The ozone layer is the part of the Earth’s atmosphere that protects the planet from ultraviolet radiation. It’s found in the Stratosphere which is around 10-50km above the surface of the earth. Think of it as a layer of sunscreen that protects us from all manner of harmful rays. Without it, life on Earth would be extremely unpleasant.

So, I’m guessing a hole in it is not a good thing

Exactly right, in fact it’s a very bad thing.

So what caused it?

Vietnam brings cement sector into new climate submission to the UN

The southeast Asian nation has made slight improvements to its 2030 climate plan but still expects emissions to increase rapidly over the next decade

Vietnam’s greenhouse gas emissions are set to grow significantly by 2030, under an updated climate plan submitted to the UN.

The country’s large cement sector is factored into the plan for the first time, which experts welcomed. But they said the overall target was not substantially more ambitious than the previous version.

Under the new plan, Vietnam committed to cut its emissions growth by 9% or nearly 84 million tonnes of CO2 by 2030 compared with business as usual projections, using a 2014 baseline. Emissions are still expected to grow by 844 million tonnes of CO2 during that time.

With international finance and support, Vietnam said it could increase its emissions cuts to 27% compared with business as usual, which would still see emissions grow by about 677 million tonnes by 2030. Tiếp tục đọc “Vietnam brings cement sector into new climate submission to the UN”

Hoàn thành cập nhật Đóng góp do quốc gia tự quyết định (NDC): Nâng mức đóng góp của Việt Nam cho ứng phó với BĐKH toàn cầu


(TN&MT) – Ngày 24/7/2020, Thủ tướng Chính phủ đã phê duyệt Đóng góp do quốc gia tự quyết định (NDC) cập nhật của Việt Nam. Bằng nguồn lực trong nước, đến năm 2030 Việt Nam sẽ giảm 9% tổng lượng phát thải khí nhà kính so với Kịch bản phát triển thông thường (BAU) quốc gia, tương đương 83,9 triệu tấn CO2tđ.

Mức đóng góp 9% này có thể được tăng lên thành 27% so với BAU quốc gia (tương đương 250,8 triệu tấn CO2tđ) khi nhận được hỗ trợ quốc tế thông qua hợp tác song phương, đa phương và các cơ chế trong khuôn khổ Thỏa thuận Paris về biến đổi khí hậuNDC cập nhật của Việt Nam xác định các biện pháp giảm nhẹ phát thải khí nhà kính giai đoạn 2021-2030 và các nhiệm vụ chiến lược về thích ứng với biến đổi khí hậu, các giải pháp thích ứng nhằm giảm thiểu thiệt hại do các tác động liên quan đến những thay đổi của khí hậu gây ra trong tương lai được xác định cụ thể cho từng lĩnh vực.

Trump Was Right to Leave the Paris Agreement. Why He Shouldn’t Have Had to Withdraw in the First Place.

Supporters of the Paris Agreement have expressed considerable angst over President Donald Trump’s decision to leave the climate agreement last week.

Regardless of the merits of that decision—although for the record, Heritage Foundation analysts recommended that the U.S. withdraw—Trump should not have had to make that call.

The Paris Agreement had all the hallmarks of a treaty and should have been submitted by President Barack Obama to the Senate for advice and consent, as required under Article II of the U.S. Constitution.

Instead, Obama signed the Paris Agreement as an executive agreement. Tiếp tục đọc “Trump Was Right to Leave the Paris Agreement. Why He Shouldn’t Have Had to Withdraw in the First Place.”

China sees an opportunity to lead as Trump withdraws from Paris. But will it?

Chinese leaders are eager for more influence on the international stage and the US has created a void it could fill

As Donald Trump walked off the stage in the Rose Garden after announcing the US would withdraw from the Paris climate agreement, one could practically hear the champagne corks popping in Beijing.

Chinese leaders are eager for more influence on the international stage, and Trump’s move opened up another opportunity for China to fill a void left by the US. Tiếp tục đọc “China sees an opportunity to lead as Trump withdraws from Paris. But will it?”

Setting the Post-Paris Climate Agenda

CSIS – UN climate negotiations are sort of like the holiday season. In the lead up there is always huge amounts of anticipation, lots of planning and logistics, and the promise of something new, merry, and important. The event itself is chaotic with lots of complicated family dynamics and the ever-present threat of someone storming off in a huff. The day after often brings plenty of leftovers to be dealt with, presents to be stored, regifted, or returned, and a sense that it is time to move on to all the things that had been put off while dealing with the big preparations.

There is no denying that for the climate community the last twelve months have been one big crescendo to Paris, a carefully orchestrated set of activities and announcements designed to drive momentum and activity toward the big moment. By any stretch this has been a tremendously successful crescendo. The country pledges that have been rolling in since this past spring total over 180 in number and cover approximately 95 percent of global emissions. By the UN’s own estimates, these pledges, if pursued in earnest, could keep the world in the ballpark of limiting temperature rise to 2.7 degrees Celsius above pre-industrial levels. Over 400 cities, 1,000 plus companies, and countless members of civil society pledged separate and additional actions. The Pope and several other groups of religious leaders weighed in on the moral imperative to tackle climate change and the United States denied the Keystone XL pipeline project – a major North American symbol of the environmentalist struggle to catalyze action on climate change. Unlike five years ago in Copenhagen , there is a lot on the table this time even before the talks get underway. Tiếp tục đọc “Setting the Post-Paris Climate Agenda”

Powering the Internet with renewable energy

December 3, 2015

Googleblog – Today we’re announcing the largest, and most diverse, purchase of renewable energy ever made by a non-utility company. Google has already committed to purchase more renewable energy than any other company. Now, through a series of new wind and solar projects around the world, we’re one step closer to our commitment to triple our purchases of renewable energy by 2025 and our goal of powering 100% of our operations with clean energy. 842 MW of renewable energy around the world Today’s agreements will add an additional 842 megawatts of renewable energy capacity to power our data centers. Across three countries, we’re nearly doubling the amount of renewable energy we’ve purchased to date. We’re now up to 2 gigawatts—the equivalent to taking nearly 1 million cars off the road. These additional 842 megawatts represent a range of locations and technologies, from a wind farm in Sweden to a solar plant in Chile.

These long-term contracts range from 10-20 years and provide projects with the financial certainty and scale necessary to build these wind and solar facilities—thus bringing new renewable energy onto the grid in these regions. For our part, these contracts not only help minimize the environmental impact of our services—they also make good business sense by ensuring good prices. Our commitment to a sustainable energy future Since we opened our very first owned data center in 2006, we’ve been working to promote renewable and sustainable energy use in several ways:

  • First, we’re building the world’s most efficient computer infrastructure by designing our data centers to use as little energy as possible.
