Inspired by the wonderful Overheard in the Newsroom Twitter feed that chronicles journalism’s lighter moments, Eco-Business started the @OHSustainability Twitter account in February to capture some of the funnier stories from the super-serious world of sustainability. 

Here are a few things that tickled us this year. 

1. The U.N. tries to make the SDGs go viral

In an unlikely partnership, Japanese comedian Kazuhito Kosaka, creator of Pen-Pineapple-Apple-Pen, arguably the most irritating, nonsensical viral video in the history of the internet, teamed up with the United Nations to create a Sustainable Development Goals-themed video.

Pen-Pineapple-Apple-Pen (PPAP) took on a new life as Public-Private-Action-for-Partnership in an equally bizarre version of the original. Quite how being in possession of a single apple and a single pineapple will eliminate poverty is unclear, but somehow this video amassed thousands of views. Mission accomplished.

2. The Man from Del Monte says he does too much for the environment

When it comes to sustainability communications, companies are usually careful to avoid chest-beating lest they risk being labelled a braggart, or worse. That doesn’t seem to worry fruit company Del Monte.

In a press release about its efforts to reuse waste water from a pineapple factory in the Philippines in January, the firm self-described as "environmental overachievers." Well, if the Man from Del Monte says so, sure.

3. Blame the farting mammals

Eco-Business gets its fair share of loony comments from climate change denialists on our stories. Here are a few that got us a bit hot under the collar this year.

In response to our article that predicted that the 2-degrees Celsius global warming horizon would be overshot, Dale Allen wrote:

"Cannot wait for the increase, I live in Canada and a 2-degree C increase would be welcome. It’s not like it has not been above that in the past, several thousand years ago before mankind thought they knew it all we had tropical rainforests in northern Canada. Guess we can blame that on the farting of large mammals."

For our roundup of the top 5 carbon and climate stories of 2016, Duane A. Fisher suggested that only the weak-minded fall for the climate change "hoax." Their comments are made all the more believable by their generous — but totally random — use of capital letters.

"Man Made Climate Changers continue the Hoax, Propaganda to Enslave the world under a Carbon Tax Scheme Ripp off! Only the weak minded are falling for this. Unfortunately a lot of the Brain-washed Morons are in leadership positions. The educated know that the Sun is the Culprit and not carbon."

In the comment thread of the same story, this gem from another American, Frank H., is the classic rallying cry of the denialist:

"Climate change is bullshit."

4. Pollution purple

Unveiled in July, the dress that measures air pollution is unlikely to be stocked in H&M any time soon, but was an imaginative way to freak us all out about bad air.

A fitting response to the denialist brigade came in April, when thousands gathered in the rain in Washington to protest against President Donald Trump’s apparent dislike of science and facts. We particularly enjoyed this protester’s poster.

5. The withdrawal method

Singapore-based speaking coach Stu Lloyd made an astute if grammatically garbled observation in May about an Eco-Business article that suggested that the world would be better off if Trump withdrew the U.S. from the Paris Agreement.

6. STDs and SDGs

Ever-outspoken Assaad Razzouk, chief executive of renewables firm Sindicatum and newly minted Eco-Business advisory board member, delivered a sobering but hilarious reality check to the sustainability community at the Eco-Business "Will businesses drive the SDGs?" event in Singapore in March when he suggested:

"99 percent of businesses think the SDGs are a type of sexually transmitted disease."
